    LIGHT AS A TOOL TO STRUCTURE URBAN PLANNING: A Socially-Oriented Approach2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    How can light positively influence and encourage pedestrians’ engagement and interaction with the urban environments at night? In this Master Thesis, I questioned how to develop nighttime urban planning from a socially-oriented approach. In order to answer this question, I studied different evidence such as two publications, three lighting designers’ and a lighting studio’ approach; three case studies analyses, two of them located in Colombia (Cartagena and Medellín) and one in Sweden (Stockholm);and my own qualitative observation and quantitative measurements studied between April and May at Norrmalmstorg and Biblioteksgatan in Stockholm, Sweden. From that review, I propose a Guideline consisted of three sections: (1) Main dimensions, (2) lighting attributes, and (3) lighting systems in urban planning. In general, this guideline is a framework to develop the analytical tools for various design stages in nighttime urban planning.

    Designing Thermal Management Systems For Lithium-Ion Battery Modules Using COMSOL2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    In this thesis, a section of a lithium ion battery module, including five cells and an indirect liquid cooling system, was modelled in COMSOL Multiphysics 5.3a. The purpose of this study was to investigate the thermal properties of such a model, including heat generation per cell and temperature distribution. Additionally, the irreversible and reversible heat generation, the cell voltage and the internal resistance were investigated. The study also includes the relation between heat generation and C-­‐rates, and an evaluation of COMSOL Multiphysics 5.3a as a software. It was found that having liquid cooling is beneficial for the thermal management, as the coolant flow helps to transfer away the heat generated within the battery. The results also show that it is important to not go below a set cell voltage at which the cell is considered fully discharged. If a control mechanism to stop the battery is not implemented, the generated heat, and consequently the temperature, increase drastically. COMSOL Multiphysics 5.3a was considered a suitable software for the modelling. For future research it is of interest to expand the model to a full scale module to fully investigate the temperature distribution where more cells are being cooled by the same coolant loop.

    Gender Based Perception of Safety: An exploratory among Stockholm residents2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A city is considered to be safe when people can move freely, without being concerned about

    being subjected to any crime. CPTED is a way to work with crime prevention in the society.

    Although safety and security are two distinct concepts, they can interact with each other in the

    work towards a more sustainable society.

    This bachelor essay explores how the perception of safety, regarding common anxiety, is

    distributed between men and women in Stockholm City. Furthermore, the perception of safety

    within the female group is examined in terms of age. This has been conducted in the form of a

    quantitative analysis, based on data from Stockholm’s safety survey in 2014. The results

    showed that the perceived safety, in a general sense, is very low among the Stockholm

    residents. In all but one of the cases, the proportion of women who claimed to be unsafe was

    bigger than the proportion of men. Most women, who felt unsafe in the neighborhood or

    transit environment, were between the ages of 25 and 44 years. The results were analyzed in a

    more qualitative form, by an assessment of its reasonableness and feedback with relevant

    theory that has been presented. This led to the conclusion that there are differences in people’s

    perceived safety, which can be explained by its individual characteristics like gender and age.

    Abstract [en]

    This thesis project investigates a method of reconstruction.

    As a case study I have choosen to reconstruct Dramaten (The National Stage of Spoken Drama), an Art Noveau palace from the early 20th century, located in central Stockholm. The building still exists today and this is not a proposal to eraze it, the building merely serves as a platform to test the method on, but in this project the building is considered as lost.

    Since reconstructing the original form of the building would not result in a resurrection of the dead building nor is possible today, the aim is instead to reconstruct the building by recreating the collective memory of the building. To reconstruct the building as it once was perceived by its vistors and the city.

    Täthetens dimensioner: En analys av vad som menas med en tät stad2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Dagens stadsplanering handlar mycket om förtätning av städer. Täta städer kan idag ses som ett slags ideal och det finns flera strategier och dokument för hur man kan förtäta en stad. Det här arbetet handlar om vad som menas med en tät stad och utreder hur en stads täthet kan mätas. Detta görs dels genom en litteraturstudie, dels genom en fallstudie. Litteraturstudien utreder olika teorier och metoder kring begreppet tät stad och hur denna kan mätas utifrån tre dimensioner; fysisk täthet, flödestäthet samt upplevd täthet. Fallstudien studerar tätheten i tre stadsdelar i Stockholms innerstad utifrån dessa teorier och metoder. Rapporten visar att det finns flera olika sätt att se på och mäta en stads täthet, vilket indikerar att en tät stad inte har en klar definition.

    Hur ungdomar uppfattar och använder staden: En studie av stadens offentliga rum med Nynäshamns kommun som exempel2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In relation to the planning and current development that is taking place today in our societies, places are created and transformed in the form of public spaces that our societies include. In the process that comes with this planning, there are certain voices that are not heard. Certain dialogues, where the aim is to reach out to the people more actively and not only invite them to dialogue, can be a tool for seeking out these voices and improving the aspect of democracy that the dialogues in planning intend to strengthen. Teenagers are one of the groups that often are excluded when planning for the society. The adult population, which is the group planning for society, has different experiences and perspectives of the public spaces than teenagers have, of which the inclusion of this group in planning is of great importance. This study aims at highlighting how teenagers in the municipality of Nynäshamns perceive and use public spaces in the municipality, in order to contribute with relevant information in future planning as well as knowledge about teenagers needs and perspectives in public spaces in relation to planning. The municipality of Nynäshamn has similar urban development strategies that many of Sweden's municipalities have, of which the study delimited this site. To gain an understanding of this subject, the research has mostly used the study of Mats Lieberg (1992) in which he defined public spaces in relation to how they are used by teenagers, if the sites are used for the purpose of interaction or privacy. Björn Anderson's (2002) argument about how teenagers divide themselves into groups depending on belonging, Jeni Hardens (2000) statement that it is the people within a place that often is the reason for the experience of being unsafe, and Danielle van der Burgts (2015) arguments about how teenagers actively use information from media, parents and friends to weight whether the sites consist of risks or not have been included. The reason for this is to highlight complementary aspects that can affect teenager’s experiences of places and their use. The study has been conducted through dialogues in the form of focus groups, including two groups of teenagers. During these, the teenagers have identified places in the city from a positive and negative point of view, which then have been the focus of the discussions. On a selected number of these marked sites, observations have been conducted and an interview has been held with an urban planner within the municipality, this to obtain further information about the sites and the uses of these. The conclusions are that teenagers use the city's public places for their need of both interaction and privacy, to a various extent. The sites are perceived based on its characteristic features, the people who stays there, and the antagonism that exist between different groups of teenagers, which affect the use of the places. The important knowledge that the study generates in relation to planning for teenagers is the realization that the possibilities for creating spaces of different kinds that work according to their needs, need to be broadened. These possibilities can be broadened by means of complementary methods, as the needs can be difficult to express and convey in various conversations.

    Boendesegregation i Stockholm: Hyresmarknadens bidragande till segregationen i staden2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Kandidatarbetets syfte är att försöka finna samband mellan den minskandehyresmarknaden och den ökade segregationen i Stockholm Stad. Andelen hyresrätterav bostadsbestånden i Stockholm Stads stadsdelsnämnder har undersökts samt olikasocioekonomiska klasser som existerar i dessa områden. Utvecklingen av antalethyresrätter mellan 1990 och 2014 har jämförs med utvecklingen i medelinkomst ochindivider med utländskbakgrund mellan 2000 och 2015 samt ohälsotalen i områdenamellan 2000 till 2014.Resultat visar att minskat hyresrättbestånd kan ha bidragit till ökad segregationenmellan stadsdelsnämnderna. Områden med stor andel hyresrättsminskning har haftkraftig ökning i medelinkomst, en liten ökning individer med utländskbakgrund samten stor minskning i ohälsotal. Samtidigt har de områden som haft minst minskninghyresrätter haft lägst medelinkomstutveckling, haft större ökning utlandsfödda ochmindre minskande ohälsotal. Författaren vill tydligt trycka på att resultatet inteimplicerar i att hyresrätter är dåligt för samhället utan istället att Stockholm blir mersegregerat efter hyresrättbeståndet som existerar i olika områden, samt att ett störrebehov av hyresrättsbebyggelse i attraktiva områden är av vikt för att minskaoattraktiva områdens sociala instabilitet.En regressionsanalys utförs för att undersöka sambandet mellan andelen hyresrättersom existerade i Stockholm 2014 och segregation.

    Närhet och tillgänglighet till fotbollsplaner i Nacka kommun: En studie genom nätverksanalyser och space syntax2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The study aims in examining closeness and accessibility of football pitches in the municipality of Nacka, in Stockholm Sweden, with the basis of network analysis and space syntax. The relations between accessibility and health are a key standpoints and related theories and previous studies in the matter has been discussed.

    The study focusses on existing football pitches in the municipality and how close and accessible these are for youths in the age of 7 to 20 years. The pedestrian and bicycling networks as well as public transportation road networks are there for examined. As a result, the study has provided suggestions for future locations of new football pitches. These locations have been analyzed from closeness and accessibility aspects as well as the capacity of the football pitches. The results have similarities to previous researches by the municipality, but does also show that some municipal areas are of greater need than previous investigations have shown. 

    Finally, two aspects must be noted. Firstly, in this study, "ball pitches" (football pitches which are not bookable for organized sport) have been excluded from the analyzes. These are highly relevant for “spontaneous sport activities” as well as daily exercise for young people. This notion becomes relevant though the municipality are discussing to make these non-bookable pitches possible to schedule for organized football. Secondly, this type of analysis can be done for a variety of different functions in the city and not necessarily just football pitches.

    Women Daily Living Room: Feminist Urban Planning toward Gender-Equality in Public Spaces; Case Study of Sätra, Stockholm, Sweden2018Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    ABSTRACT

    In 2014, Sweden became the world's first self-defined feminist nation and a place where gender equality has a strong ideal within the country's national identity. However, the issue of gender equity remains unaddressed in some area across Sweden. Sätra district in Stockholm located between Bredäng and Skärholmen is one of those examples that women usually suffer from inequality. By considering social equality as a fundamental principle of good urbanism, the need for feminist urbanism feels necessary in this context today. Through the lens of feminist urban planning, mainly focused on women in Sätra and tried to reflect women's voices in every urbanization policies. The study is going to examine the role of gender in public space, its socio-spatial implications and create feminist participatory strategies to empower women. In this research, Mothers considered the effective groups of women as their educational role in their family and their central role in the community awareness raising is undeniable. In this way, strengthening mothers role in urban settings can have a powerful multiplier effect on urban development. So that's what has been considered in the whole process of decision-making. This would make an inclusive and women-friendly public space for girls and women where is safe and secure and responsive to the needs of all kinds of people. So that's what has been considered in the whole process of decision-making.

    Light as a Tool for Generating Identity: Lighting proposal for part of Islamic Cairo, Egypt2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Each city has a unique image and special things to offer to citizens and visitors. It is

    this unique image that differentiate between the different cities. The uniqueness of

    the image of the city is derived from the urban identity of the city and its public

    spaces. The purpose of this thesis is to define what are the factors that contribute in

    defining space identity which were found to be the physical stationary structure, the

    users and their interaction with the space which result in creating memories and

    experience and the history of the space.

    Based on this definition a connection is made to define how can urban lighting

    contribute in fulfilling those factors This connection is made through the study of

    urban lighting techniques, the different approaches of lighting masterplan for three

    cities and users perception of the space aiming to reach a final goal of a conceptual

    lighting proposal for Al-Moez Ldin Allah street which is part of Islamic Cairo in Egypt.

    Al-Moez street is considered a landmark and a touristic space in Cairo because it is

    rich with heritage landmarks and amazing medieval architecture. The street is not

    only considered a touristic space, but it is also used by locals and a lot of Egyptians

    already are emotionally attached to the space.

    Finally, a discussion part is following that aim to reflect on the steps taken to

    approach the goal of this thesis and evaluate the lighting proposal based on the

    vision of this thesis, and it shows that keeping users as the first priority in the design

    process will result in the most efficient lighting proposal.

    Next year will United Nations Children Convention with a high probability become established as a law in Sweden. Article three and twelve states that the best of the child will be first priority in all actions regarding the   child. What decides is the best for the child have to be accessed in each case and regards will be taken according to the child's own will and   experiences. In my project I have chosen to act out of this scenario and ask myself the question how I as an architect can produce an architectural proposition with regards from the children's own perspective.

    REVERENCE and COMFORT

    The project is an endeavor to create a building that evokes reverence for knowledge and at the same time is perceived as safe and pleasant.The hope is that the building, owing to its monumental façade, will embody respect and confidence in knowledge. This is especially important in a time when this reverence to a large extent seems to be lacking in society.At the same time, a safe residence is a fundamental prerequisite for creating a study environment that offers peace and quiet and the opportunity to focus. One way to achieve this safety is to create homely and comfortable residences.The main focus has been on creating a healthy and inspiring working environment. Great focus has also been placed on creating an ecologically sustainable building.

    SITE and PLACEMENT

    The building is facing Hammarby Lugnet to the southwest and thereby shields of the noise from the highway to the northeast. At a distance it is perceived as monumental, as if it has claimed the turbulent area, and it radiates calm and inspires confidence.

    SEQUENCE and MATERIALS

    In order to submit a feeling of safety, it is required that the rooms are perceived as animated. They must convey the feeling that someone has put work into creating a building that is unique, a building which it is impossible to mass-produce. This applies to both sequences and details.A strict general plan enables more complex spacial structures. The residences are located to the north and west, while the public areas are located, facing south and east. To facilitate finding one´s way in the building, the bearing inner walls of rammed earth are color coded, by mixing pigments into the earth. Rammed earth elements also dominate the buildings external expression and anchor it to the ground.The closer you get to the building and the the farther into it you move, the safer you will experience it. This is due to changes of materials and scale, but also to the spatial sequences and how the rooms change volumetrically.The way to the recidences and classrooms – the safest parts of the school – either goes through the great entrance hall or one of the stairwells. The materials change as the rooms get smaller and smaller; the smaller the room the less visible rammed earth and the more visible wood.

    Measuring the attractiveness of a city block2018Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    Nowadays the competition between cities is something very common, especially between cities of different countries. But this competition it can be observed even between cities of the same country or between districts of the same city. Based on this phenomenon municipalities try to change and become more sustainable (socially and environmentally), implement more green spaces in their urban core, create vibrant local environments and launch campaigns in order to create liveable districts, improve their local economy and survive this growing competition. In other words, cities want to become more attractive.In Sweden cities are also part of this global trend and since they are growing economically they try to create an urban environment that is desirable for its citizens. In Stockholm’s Översiktsplan there are different main goals, such as “The growing city (växande stad)” which is analyzed as “An attractive big city” or “Good public spaces (God offentlig miljö)” which is analyzed as “Mixed use urban space”, “Inviting public space”, “Living local centers” leading to the question how do these correlate and how do they affect each other.The reason of this research is to understand what is an attractive area in a city and find out a way to measure attractiveness by using spatial or non-spatial factors who play a major role on how a city is perceived. It is known based on existing research and literature, that many different factors are involved for a place to be considered as attractive, such as the distance from the means of transport, the distance to public amenities, house affordability, vibrant lifestyle, the distance from market places, social equality, the distance from the city center, the proximity to nature and many others, but there is no index that uses all these factors and calculates an attractiveness score.So this research aims in the creation of an attractiveness index, by formulating a lot of different indicators (social, geographic, economic, etc) based on the Översiktsplan goals and the calculation of attractiveness of different areas in Stockholm. The areas are SoFo District in Södermalm, Skarpnäck suburb in the south and Tensta suburb in the north. The main goal of this research is to improve the urban quality in Stockholm by identifying problematic areas, in order to increase the awareness about urban quality and the way to accomplish this research is the use of Multi-Criteria Evaluation in collaboration with Geographic Information Systems.Based on all the above the research question in this thesis will be: How city’s block attractiveness is measured with the use of Multi-Criteria Evaluation and the implementation of Geographic Information Systems?

    Domain dynamics in stoichiometric lithium tantalate revealed by wet etching and on-line second harmonic generation2017In: Journal of Applied Physics, ISSN 0021-8979, E-ISSN 1089-7550, Vol. 121, article id 184103Article in journal (Refereed)
    Abstract [en]

    The effect of chemical etching on the stability of domains in periodically poled stoichiometric lithium tantalate is studied by on-line second harmonic generation and microscopy. It is found that wet etching directly after poling leads to domain-wall movement, resulting in back-switching or domain merging. Head-to-head domains tend to backswitch, while tail-to-tail domains merge. For samples where the domain structure stabilized for longer time, no domain motion is observed when etched.

    Daylight Control System For Windows: How can sun shading for individual offices be designed to prevent glare at the same time preserve daylight and a view out2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Daylight is an important factor to offices, but it is not utilized to its full extent today when it comes to the occupant’s comfort and well-being. A big problem with daylight is the glare that wants to be eliminated from these environments. Even if there are a vast variety of products and solutions to prevent the glare, other qualities as daylight and a view out are eliminated or reduced too. As both daylight and a view out provide significant psychological advantages for occupants in office environment, a study of existing daylight control systems and humans comfort preferences was investigated. The investigation was developed and led to a strong concept, an artefact. With the capability to preserve both daylight and a view out, even when glare is prevented. SmartFilm was found as a technique with best control over the material, when it comes to flexibility of choose from transparent to opaque. But this technique is today used more as a privacy system. With the study based on visual comfort preferences, the form and the function behind the material is interpreted differently to allow it to be a daylight control system. Studies shows that the most important characteristic of a view is its horizontal stratification and how it, by dividing the view into three layers: the sky, the city/landscape and the ground, provides with the functions we need for well-being and productivity (see chapter 2). The SmartFilms is therefore integrated in three layers on a window, allowing the user to adjust each sections opacity through a special designed device connected to the SmartFilms. By controlling each section separately, the whole window does not need to be fully covered. The daylight control system will in this way, theoretically, prevent the experienced glare, at the same time provide with daylight and a view out.

    A study on task lighting in shared residential kitchens highlighting the relation between multiple users, illuminance and task performances.2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Shared spaces have proven to be the most sustainable solution in the midst of growing demand to implement sustainable lifestyles and at present, co-living is the most trending housing option. In these coliving spaces, the common shared spaces are very important among which kitchen is the most critical one as most of the tasks are carried out there. The main objective of this study is to find if a relationship exists between task lighting, illuminance and multiple users in shared residential kitchens. Limited research in this area has been the primary motivation for this study. Furthermore, during the course of the study, the importance of flexibility in the task lighting for shared residential kitchens was investigated.

     

    Realizing the objectives, the study aims at answering the following main investigation questions:

    • Is task lighting in a shared kitchen designed with the number of users in mind and does it consider the different ways in which they perform different tasks at the same time?
    • Should the lighting design standards be reconsidered for shared residential kitchens?
    • Would flexibility in the lighting devices be beneficial for shared kitchens ?

    The main investigation questions are answered with the help of the following sub-investigation questions which mainly highlights the relation between the multiple users, illuminance and task performances.

    • Do multiple users affect the various performances carried out in a shared kitchen?
    • Are there any shadows cast by the multiple users in a shared kitchen? Do they affect the illuminance levels in the task areas and thereby affect the visual and task performances?

     

    Case studies of two different shared residential kitchens were carried out. The methodology of the case study involved two stages, complete site analysis and an experiment.

    The experimental set up is adapted from McGuiness, Boyce and Harker‘s investigation study “The effects of illuminance on task performance in domestic kitchens” and was modified to suit this  study. The experiment was conducted in two different scenarios. Quantitative and qualitative analysis was carried out during the study.

    The end results of the experiment proved that there is a strong influence of multiple users on the task performances without having any major impacts on the lighting conditions. This indicated that new lighting standards have to be framed for shared residential kitchens in the aspects of ergonomics and flexibility. The importance of flexibility in shared spaces and in shared residential kitchens was realised was considered just beneficial in terms of mood, comfortability and practicality.

    To learn about the associative school environment, have I studied Hans Scharoun’s architecture that emphasizes the social environment of the school and the associations between individuals and society. Learning is achieved through the gradual increase of social integration, where class rooms gradually become more integrated in a broader context, the higher the grade the students attend. The school is often likened to the city.

    Therefore, I have designed the school so that the younger grades have easier to run and play and have more concentrated teaching in the periphery of the school building. The older move in a larger part of the school's premises, between floors and more independently in the public, central parts of the school.

    At the same time, I have worked tectonically and focused on brick walling. Different types of walls have directed the design of the building. The size of a 250x120x62 brick has determined the shape of a supporting wall or a non, an outer wall or if it stands inside. Above all, the wall does not need to be space-separating, but can be seated and played on.

    Abstract [en]

    Connected public lighting for more sustainable and liveable cities is highly demanding research in lighting design field through human centred design approach. While following this understanding, this thesis aims to answer the question “How a networked public lighting can be created in order to enhance the needs of the pedestrians in Fredhällspark?”. To investigate this study, a background research was studied in the relevant topics of urban lighting, followed by the study of human safety regarding to this topic and lastly the possible new lighting technologies. The main study is involved in a pedestrian path at Fredhällspark in Stockholm, Sweden, in two months duration in the spring time of 2018 by conducting user surveys and taking the lighting measurements. Based on the results the study showed, a lighting design proposal is developed with a site-specific approach in order to make it up-to date and sustainable for future urban environments while complying with the requirements of the users.

    Principles of Designing an Experiential Lighting Showroom: Finding the Balance between Demonstrating the Experiential and the Technical-Aesthetical Qualities of Luminaires2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    An analysis of existing showrooms showed that absence of atmosphere makes it hard for clients to imagine effects in a context, and that lack of guidance by the light makes the experience of the showroom overwhelming or static. Also, clients often prioritize luminaires' design over light effect, even in architectural lighting where design should be negligible. This thesis investigates whether it is possible by prioritizing light effect, to optimize the showroom experience and to direct clients' focus on the light, while minimizing the influence of design on the impression and eventually choice of luminaire. In order to achieve these goals, three main concepts are suggested – guiding light, contrasting atmospheres and sequence of presenting light effects first and luminaires afterwards. These enable good communication about light which is essential for clients to focus on the atmosphere created by the light, rather than price and design. Experiments were conducted in the basement of a Croatian company's office, where the exhibits were not the luminaires, but their light. Visitors' priorities before and after going through the installation changed significantly, which might mean that the light effect made an impact and influenced examinees to base their choice of luminaire more on light effect, than design. It is concluded that the used concepts contributed to putting more focus on the light itself. Instead of focusing solely on light experience or product, a balance between the two was achieved by prioritizing and showing the light effect first, and only afterwards joining it with the product, thus offering visitors a more complete experience of the luminaire.

    Using as a springboard the forthcoming development of Nacka into an urban cityscape, I aim to investigate the challenges and possibilities of designing and integrating a public building in this new context. My thesis project is a proposal for a new Aquatics Arena in central Nacka. The questions I have worked with all begin with the task of designing for the programme in accordance with the future environment, and producing value beyond the building itself. I have worked with a topographical concept. The main spaces are lowered into the ground and the sloping roofs have windows to allow desired daylight conditions. Besides the essential function an arena the programme is extended with spaces for a gym and health practitioners. The Aquatics Arena is accompanied by direct connections to a public space and elevators leading to a new subway station. The idea is to achieve a symbiosis between the three public entities and making the arena a civics centre in the growing city.

    The project has aimed to preserve the qualities that the project site Henriksdalshamnen has to offer, such as the views,  the nearby water and its urban character. The challenges have been the elongated site and the noises from Värmdövägen. As for the builidng, the vision has been to create an ”aha-experience for everyone” which means that everyone learns in different ways and therefore the a school has to offer different kinds of learning methods.

    Sjöängen Elementary School has a shape that protects the playground and Henriksdalshamnen from the noise from Värmdövägen. Instead the school opens up for Henriksdalshamnen. It is located in the northeast part of the site to maximize its function as noise protection and also to make the building visible from as many views as possible.

    The ability to move flawlessly in the building has been important in this project. Therefore the movement has been placed in the front of the building and combined with other functions such as the library, the cafeteria and cloakrooms. Closed functions such as offices, classrooms and the kitchen have been placed in the back of the building.  In the classroom, the school day begins around the carpet. The teacher does not have a lectern but sits in the center of the classroom by the table of meetings. Every pupil has his own seat by a group table and the classroom also offer seats for individual work. There are also group rooms available close to the classrooms. If a pupil is in need of extra help, the library has rooms for special teaching. 

    The school is located in Hammarby Sjöstad, a district of Stockholm that has focused on sustainability since its beginning. To build a school in solid wood felt like a matter of course for this site. The building has a flooring of cross-laminated timber and the walls are a combination of  cross-laminated timber and cross-laminated beams.

    The use of spatial and temporal analysis in the maintenance of road mortality mitigation measures for wildlife in Ireland2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Urbanisation and a growing global population have caused our road networks to expand rapidly in the past decades. The consequences of transport infrastructure for wildlife include traffic mortality, habitat loss and habitat degradation and the negative impact of a road extends far beyond the road itself. In Ireland, there are mitigation measures for wildlife mortality in place on all major roads. Mitigation measures can help reduce wildlife-vehicle collisions and increase habitat connectivity but need to be properly monitored and maintained following implementation. This study was carried out in collaboration with the Environmental Policy & Compliance department at Transport Infrastructure Ireland (TII), a state agency in Ireland responsible for national road and public transport infrastructure. It applied various spatial and temporal analyses methods in order to ascertain how best to prioritise critical road sections and times for maintenance. The significance of the study is that recent site visits carried out in Ireland found that 66% of mitigation measures were of inadequate standard. The methods were applied to roadkill data taken over an eight year period on the M3 motorway in county Meath, Ireland. This case study was chosen as mitigation measures, such as underpasses and mammal underpasses, have been in operation since its’ opening in 2010. It was found that temporal analysis could provide an insight into whether roadkill was increasing or decreasing annually as well as what months were most recommendable to carry out maintenance. The spatial analysis began with using Ripley’s K-statistics to first determine whether or not clustering of roadkill was occurring along the study area. Four different methods of locating hotspots along a road network were then applied and compared; Malo’s method, 2D Hotspot Analysis using Siriema Road Mortality software, kernel density estimation using SANET and finally KDE+. The findings showed that, despite mitigation measures being in place, hotspots were still occurring indicating road sections experiencing higher numbers of roadkill than expected in a random situation. These sections could then be prioritised for maintenance. It was found that the KDE+ software in conjunction with the use of a roadkill data app was the most recommendable approach. It was also noted that that the app should be expanded to other road classes and rail. It is recommended that this be made a standard protocol, comparable on a national level, for the prioritisation of mitigation measures for maintenance. Finally, it was recommended that more public awareness about wildlife-vehicle collisions and mitigation measures be raised. In the future, the app could also be connected to GPS systems to warn drivers of critical road sections. If these methods and recommendations are applied to the Irish road network, a reduction in roadkill should be observed.

    Studies on Rechargeable Fe-air electrodes in Alkaline electrolyte2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Energy storage system is an important component in the energy system based on variable renewable energy sources into the grid. Energy storage system could contribute to decarbonization, energy security, offset the demand and supply of the electricity sector, especially for the electric grid. These can be either mechanical, electrochemical, chemical, electromagnetic or thermal devices. The most important functional characteristics of an energy storage system are capital cost, roundtrip efficiency, energy and power rating, response times and cycle life. Electrochemical energy storage systems (EES) have the following edge over the other systems: fast response time, relatively short duration of storage, size, high efficiency, a decentralized installation which is closer to generation or consumption site.

    The focus of this thesis is on the development of cost-effective iron anode materials and electrocatalytic air electrodes for Fe-air batteries that potentially could become as an energy storage system. Iron-based systems are attractive due to their safety, cheapness, non-toxicity and ubiquitous availability of materials. However, both the anode and cathode parts have numerous drawbacks that need to be addressed. The anode exhibits poor charge efficiency, rate capability and low capacity utilization while the cathode has sluggish kinetics, poor activity, structural stability and the numbers of active non-noble metal catalysts are limited.

    This work utilized Cu and Sn-doped iron nanomaterials and different additives (Bi2S3, CNT, LiOH) to enhance the performance of the iron electrode. The performance of the electrodes were evaluated using the charge/discharge cycling, rate capability, cyclic voltammetry (CV), galvanostatic and potentiodynamic polarization measurements, in operando charging measurements combined with mass spectrometry. The fresh and cycled electrodes and powders were characterized by ex-situ XRD, BET, SEM, TEM , XPS and Raman spectroscopy. The most striking results are the prevention of nanoparticle agglomeration, increased charging efficiency (80-91%), effect of Cu and Sn dopants on specific capacity (367-603 mAh g-1) and improved performance of the electrodes at high charge current densities.

    In the subsequent air electrode part, non-precious metal La-doped CaMnOx, nano Co3O4 and NiFeOX electrocatalysts were synthesized using co-precipitation and hydrothermal methods. Both the single and mixed catalysts were used as bi-functional catalysts for oxygen reduction and evolution reactions (ORER). The catalysts were characterized by XRD, SEM, TEM, BET, Raman and XPS. The electrocatalytic activity and stability were assessed in alkaline solutions on gas diffusion electrodes and glassy carbon electrode by linear sweep voltammetry (LSV), CV and rotating disk electrode (RDE). Furthermore, the mixed catalyst and NiFeOX showed excellent bifunctional performance such as high activity and stability achieved by the hybridization of the two catalysts and the effect of catalyst loading on the electrocatalytic performance. These findings can help to develop a cost-effective material for Fe-air batteries.

    Undervisning om hållbar utveckling: Utveckling, implementering och utvärdering av ett lärarstöd2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Sustainable development has a prominent role in the curriculum for Swedish primary school and the ambition is that sustainable development will permeate the school’s work. Though it has been showed that teachers think that implementation of sustainable development is difficult to execute in practice. Perceived obstacles are, for instance, lack of time, knowledge within the area and inspiring examples and that sustainable development is fragmentedly presented in the curriculum. This leads to the fact that sustainable development is in practice either dealt with as small, separate units which in turns leads to the fact that students do not see the context, or with transdisciplinary teaching in specific themes that demands much time that teachers have difficulties to find time to teach all other matter in the curriculum.

    In this study a set-up of two teaching tutorials have been developed and evaluated in order to give a basis for a new teaching support, “Rädda vattnet – Rädda världen” (Swedish, “Save the water – Save the world”). The support can contribute to give the students a more holistic understanding of sustainable development, that is to say a more interdisciplinary understanding, if the teaching support is further developed. The two teaching tutorials were developed within the water-, chemistry- and technology related areas “plastics in the oceans” and “acidification”. They were then evaluated with help of a focus group interview consisting of teachers for grade 4-6 who had tested the teaching tutorials with their students.

    Four aspects that the teachers thought were significant for the applicability were identified, namely that the teaching support:

    • Make the students think it is fun

    • Is teaching content that are authentic and/or exists in the curriculum

    • Is simple for the teacher to use

    • Take time consumed and other frame factors into consideration (for example size of the student group).

    Abstract [en]

    DHL Parcel has an old model for notification to their customers. The purpose of the assignment was therefore to investigate how new or alternative methods can be used in a new model. The new model should be reliable and profitable.

    Research and interviews were conducted to get an understanding of the present situation and to find ideas for a new model. Notifications by mail is the largest cost in the current model. Research and meetings with LINK Mobility showed that “Facebook Messenger” is the most developed method to use as a new notification method.

    The new model presented in the results suggested that the mail being sent on day 7 should instead be sent on day 3. This by reading the list of deliveries of SMS and only send mail to customers not reached by SMS‐notification. The new model is calculated to reduce the yearly cost by 3 million SEK and high level of reliability.

    At the end of the report, reflections on the work are presented. Recommendations to DHL for continued work on implementation plans and other necessary steps before an implementation of the new model are presented.

    This study has been conducted due to the need of a boost of the Swedish school's mathematics education. The aim has been to be able to show an idea of how high school mathematics education can be customized as a result of an extended and more targeted use of sample solutions. This has been done by introducing an alternative teaching method into two classes at a secondary school in Stockholm. The students has then performed mathematical tests with and/or without the alternative teaching method. In addition to mathematical tests, interviews and surveys have been conducted. The results of the study indicate that students' performance increase when teaching with sample solutions. Furthermore, the study points out that those who are most successful in raising their mathematical results often are the students who usually perform the weakest in regular education. The study also shows that students with different academic background appreciate to work with sample solutions, and can find their own way in how to use them. To summarize, this work indicates that sample solutions can be used as an element in mathematics education, for example, when introducing new procedures or theories in order to easier and less time-consuming provide students with the support they need and require.

    Classical Formation Patterns and Flanking Strategies as a Result of Utility Maximization2019In: IEEE Control Systems Letters, ISSN 2475-1456, Vol. 3, no 2, p. 422-427Article in journal (Refereed)
    Abstract [en]

    In this paper, we show how classical tactical forma- tion patterns and flanking strategies, such as the line formation and the enveloping maneuver, can be seen as the result of maximizing a natural formation utility.

    The problem of automatic formation keeping is extremely well studied within the areas of control and robotics, but the reasons for choosing a particular formation shape and position is much less so.

    By analyzing a situation with two adversarial teams of agents facing each other, we show that natural assumptions regarding the target selection of the agents and decreasing weapon efficiency over distance, can be used to optimize a measure of utility over agent positions. This optimization in turn results in formations and positions that are very similar to the ones being used in practice. We present both analytical results for simple examples as well as numerical results for more complex situations.

    NATURE MOVEMENT - School in Mälarhöjden

    Nature movement was created by a lump of clay. It all began with study visits to schools and various literature on the subject (eg De Jong and Bjurströms case study, Skolmiljö och välbefinnande – utformning och upplevelse) and thoughts about my own schooling. With these sources of inspiration, the school slowly began to take shape in my thoughts and in the clay pump on my desk. The houses are placed in harmony with nature in a long irregular loop along the plot of land, creating a enchanting form with the wild nature on the school's three hills in the center. The house length means that there is a natural progression from year to year. The schooling begins with a start in pre-school autumn in the loop and continues to move closer to the Stora huset. Fifth grade and upwards is placed in the Stora huset with fifth grade on the second floor and sixth grade on the floor above it.    In the goal of creating a school, which is a high priority for knowledge, I have specifically thought of designing both good classrooms and breakpoints. What I have emphasized is that the acquisition of knowledge, a kind of inhalation, has to be endured with breaks and exhale, as students get power and can let the thought be free again. Some students gain power by sitting and philosophizing, other students through physical activity. I do not want to underestimate the momentum. Both moments are important! The day is thus made up of contrasts.    A "residence" in my school project Naturform i rörelse consists of two classrooms with each group room and a shared generously designed break in the middle. Inhalation (learning) takes place in classrooms and exhalation (rest / play) in the restroom and at the schoolyard. The idea is that you should not mix the energies and use wrong rooms for the wrong purpose, I mean. Where activity has its place. The clarity of the layout makes it easier for the students (just as research shows that mobile activity in bed worsens sleep).    Due to the fact that each item has its place, I have designed classrooms and restrooms along the way.    For the classroom, I have let all walls have 90-degree angles and retain the raw, unpainted concrete, this to create as quiet a learning environment as possible. All classrooms, even in the Large House, have three windows from either the right or left side of the classroom. In the smaller classes, pre-school class up to 4, the ceiling of the room has a slope, from 2.5 meters to 5 meters. The sharp slope gives a clear direction to the room. The attention of the students is directed to you where the ceiling height is highest, and the teacher is placed (high ceilings for knowledge). Each classroom has concrete floors to allow games and carelessness, and is also equipped with a washbasin with running water and a large workbench for the aesthetics.    The break room is in contrast to the classroom in both function and design. It is a large osymmetrical space because the walls are not 90-degree. The roof also has a slope, but in this room the walls lean towards the center of the room. Where the ceiling is at its peak, it opens to the sky in a large lantern that illuminates the room. The walls in the restroom are laserized in different dull color shades in layers of thin layer layers that give a deep surface.    The schoolyard is designed to promote outdoor play. It is designed in contrast to a square hard-crafted surface with the supplied "playground kit" installed.    Nature has an obvious and central place at times the houses. For the best possible leakage, I have created two more litters in the schoolyard by the undisclosed earth from the basement. It spreads wild nature with snowy bushes, tall pines with thick tribes and large pebbles. Why install a pastel climbing position when children love to climb trees? Why buy a prefabricated rocking position when it's enough with a rock made of a thick rope and a rough plank? In the school yard there are also two basketball baskets and a tricycle store that the children can ride around the school yard.    The kind of play that takes place at the schoolyard is adapted to a high degree of what the place offers, I mean. A more natural and organic schoolyard attracts imagination, play and movement!

    A sustainability assessment for public buses: A multi-criteria approach2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Many city planners, regional authorities and transport providers are tasked with the challenging job of selecting which type of public buses are suited to their location and priorities. The challenges of which are multidimensional in nature due to different policies to adhere to as well as economic, environmental and technical tradeoffs between options. The aim of this report was to provide decision support in the choice of powertrains and energy sources for buses in public transport systems. The methodology used was a multi-criteria analysis.

    The assessed transportation options include buses running on diesel, biogas, fatty acid methyl esters (FAME), hydro-treated vegetable oils (HVO), bioethanol as well as battery electric vehicles (BEVs) assessed separately as opportunity and overnight charging. Suitable bus solutions were broken into six key areas to be considered when selecting fleets. These involved economic, technical, reliability, infrastructure, environmental and social issues. The economic considerations highlighted: the cost of ownership and the market share of vehicles. Vehicle performance considerations included: the range/refuel time of a vehicle. Considerations involved in delivery reliability were: national energy security, whether there was a short-term backup fuel as well as current and future policy support. Another consideration regarding infrastructure was: the required level of change required. Regarding environment and energy, considerations of merit involved: well-to-wheel greenhouse gas reductions, air pollution in relation vehicle regulations, noise levels, nutrient recyclability as well as associated resource impacts. The social considerations were determined as: public opinion and job creation.

    From the compiled results assessing each criterion the grading matrix suggested it was biogas buses followed closely by HVO buses that scored the best. Weighted results were also conducted, emphasizing the most important criteria according to surveyed stakeholders which resulted in HVO and Biogas again performing the best.

    Inclusion of local actors in Sustainable Development Projects: Evaluation of co-management in Sustainable development projects based in the Bolivian Amazonia2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Abstract 

    One of the challenges for projects that work on sustainable development is to measure and analyse the level of local participation. Local participation is considered a key aspect in order to implement long term processes that can contribute to conservation of ecosystems and also improve the living conditions of local actors. 

    The aim of this thesis is to assess two case studies ongoing in the Bolivian Amazon according to co-management principles. This aim raises the following core objectives: -Review literature on co-management for sustainable development projects. -Develop a qualitative framework to assess the perceptions and performance of projects. -Assess two existing projects according to the established framework. 

    This thesis analyses the work that a non-governmental organization (NGO) does in two different communities in the Bolivian Amazonia in projects related to sustainable development and conservation. One is an indigenous group called Tacana located in the department of La Paz; the other is considered a multy-ethnic population that is formally established in a region called Santa Rosa del Abuna in the department of Pando. Even though these two groups show cultural and organizational differences both work on the harvesting of non-timber forest recourses. The recollection of the products that come from the forest represents the main economical income for these populations. 

    To evaluate the projects, visits to the communities where done in order to make interviews, participant observation and to see the relations between the different actors involved in the projects. Several interviews were also done with the members of the NGO in their offices in La Paz and Cobija. 

    To prepare this evaluation process, different theories have been used in order to create specific criteria to evaluate the level of success of co-participation processes into the projects. Co-management and Co-generation of knowledge have been seen as interesting tools that can be used to develop a framework that can evaluate the local participation in different projects. To develop this, six criteria have been used to analyse the local participation on the projects and how this participation can be improved in the long-term perspective. 

    This evaluation can help to increase the local and active participation into the projects but also can help the members of external organizations (in this case the NGO) to understand the relevance that local participation and local knowledge can have for the projects. The idea is that this kind of evaluation can be used by different actors/organizations in order to find possible weaknesses during the implementation of projects related to sustainable development.

    Abstract [en]

    Synchronisation of paddle stroke is an important aspect within the sports of paddling with multiple paddles in one boat to maximise the velocity. Hans Rosdahl from The Swedish School of Sport and Health Sciences, GIH, therefore provided a task to develop a mobile phone application that offers feedback to the paddlers using the application if their paddle stroke is synchronised with the paddler in front. A pre-study has been carried out to investigate possible sensor alternatives that are available, and an application has been developed for the mobile operative system Android. The application connects to an IMU, Inertial Measurement Unit, sensor that measures inertia to determine the orientation of the sensor node. The application receives sensor data from the IMU from the user paddler’s and the front paddler’s sensor nodes and each sensor determines when a paddle stroke has occurred using its orientation. The data showing a stroke is used to calculate the time difference between these strokes to evaluate if the user is synchronised with the front paddler or not. After this evaluation, the user receives a visual response of their synchronisation level on their screen.

    RTOS med 1.5K RAM?2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Internet of Things (IoT) is becoming more common in today's society. More and more everyday devices are connected to the wireless network. This requires costeffective computing power, which means that it can be beneficial to investigate the microcontroller and how they would cope with this task. These can be seen as smaller compact computers which despite their size offer a lot of performance. This study aims to inform if any existing operating system can work together with the microcontroller PIC18F452 and how many processes that can run in parallel given the MCU's limited memory. A survey and an experiment were conducted to answer these questions.

    Different choice of methods was investigated and discussed to determine which method would generate the best results. A survey and an experiment were conducted to answer these questions. The experiments required a special development environment to be installed and the generic FreeRTOS distribution was ported to both the correct processor and the experimental card. The porting succeeded and experiments showed that the research question could be answered with a yes. You can run a real-time operating system on an MCU with only 1,5 kB RAM memory.

    During the work, the project also found that Amazon built its IoT on FreeRTOS. However, they had invested in a more powerful MCU. The effort would thus emphasize it as a more future-proof approach.

    10 billion people will inhabit this planet by 2050. In order to feed such a large number of people research shows that food production will need to increase by 70%.This project explores what a foodcentric city planning can look like, where agriculture is not only integrated into the built environment, but rather the main generator of urban form. A block typology specifically tailored to create optimal growing conditions is rolled out as a high density agricultural grid across Bromma airport, and addresses issues of combining large scale structures with small scale human life.

    Optimisation before growth: New property formations for a resource-efficient use of the existing building stock2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The building industry accounts for around one third of the total energy use and GHG emissions in Sweden. Despite the implementation of energy efficiency measures focusing on new buildings, embodied impacts from material extraction, manufacturing, construction and maintenance have grown in significant proportions.

    While cities like Stockholm are currently experiencing a strong demographic growth and a high pressure on the supply of new spaces and facilities for new residents, national environmental goals aim to reduce energy use and GHG emissions in the coming decades. For instance, the new Climate Act in Sweden expects the country to become carbon neutral by 2045 and the European Commission urges the decarbonisation of national building stocks by 2050.

    The dual pressure of growth and environmental targets urges the exploration of alternatives for the supply and use of space. In fact, some sources indicate that many spaces remain unused during several hours a day/week and estimations show that most of the buildings that will be in use in 2050 have already been built today.

    This study explores the potential for a resource-efficient use of space in the existing building stock in Stockholm, leading to a positive impact on the reduction of energy consumption and GHG emissions. The inquiry is conducted with a mixed methods approach in three sequential steps: the identification of relevant stakeholders, instruments and initiatives; the analysis of use of space in a sample of commercial spaces at the street level; and the formulation of strategies allowing an increase in their temporal and spatial capacity.

    The study suggests that one way to optimise the use of space in existing buildings is to create new property rights. Specifically, it illustrates how merging commercial spaces on the street level through the constitution of 3D properties can increase the capacity to accommodate activities in space and time. Together with digitalisation and the development of new services based on sharing solutions, this opens up new possibilities for decreasing new construction and to absorb new demands for heated floor area.

    Architecture, Home & Daylight, -The openings affection on the quality of a space2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis investigates how the opening in the envelope of a typical Swedish commercial residential project could be treated differently from today. Instead of using the openings only to create a unique facade or to reach a certain daylight factor I try to find out how the openings could be treated in a manner affecting the perception of the interior space. Conscious use of qualities related to the opening, such as daylight and view has been used as a design tool. This project is not to be seen as a traditional design project but as an investigation about daylight and openings in commercial residential architecture in Sweden today. Also the project is looking into the industry’s relation to the subject of daylight.

    Sun Tunnel2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis project aims to repurpose an abandoned railway tunnel in Eriksdalslunden, Stockholm into an experimental activity/farming center for the purpose of teaching people of all ages different farming methods. The learning center implements exciting farming techniques such as aquaponics, where plants get their nutrients from live fish.  This center also teaches about the new technologies that make it possible to grow plants beneath the earth´s surface. These technologies harness the benefits of the sun into a concentrated form and then leads it deep underground. Repurposing unused underground spaces such as this can help develop our cities in a more efficient way.

    Linking Squares-Study based on KTH Campus2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    KTH Campus is open to the city but when we walk around we feel it is very isolated. Most people gather in the south square or in the triangle park in the middle. These two gathering points are separated from each other. Drottning Kristinas Väg acts as a quick path for cars. Along this road there are many empty outdoor spaces but most of them are not used by people. It is such a waste. Then how to make better use of the existing parks or squares and how to use parks or squares as linkage of public spaces are what I want to explore.

    Palmträdgården2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    I've created a winter garden and restaurant as a part of Stockholm's most central, loved and well-attended park, Kungsträdgården. The goal with this project has been to design a public space that adds a functional as well as an aesthetic value to Stockholm, its inhabitants and visitors.
