    Undersökning av direktuppspelning som pedagogiskt verktyg inom MOOC2018Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Storskaliga öppna nätbaserade kurser, MOOCar, med självstyrd studietakt skapar en

    lärandesituation där kursdeltagaren står i centrum och aktivt kan påverka sin egen

    studieprocess. Ett problem som kursdeltagare upplever är att de får begränsat stöd

    och hjälp av lärare eller andra kursdeltagare. Möjligheten till social interaktion är avgörande

    för främjandet av lärandeprocessen i nätbaserade utbildningar visar tidigare

    forskning. Studien ämnar därför att utforska om direktuppspelning (livestreaming)

    kan användas som ett pedagogiskt verktyg för att främja den sociala interaktionen

    mellan kursdeltagare samt mellan kursdeltagare och lärare i MOOCar med självstyrd

    studietakt.

    Utifrån en systematisk litteraturstudie utformades ett moment med direktuppspelning

    via Twitch som testades i praktiken i en MOOC som gavs av Kungliga Tekniska

    högskolan (KTH). Vi utvärderade sedan momentet genom en enkät till kursdeltagarna

    och intervju med läraren. En intervju genomfördes också med ytterligare en

    lärare på KTH som tidigare genomfört ett antal kursmoment där direktuppspelning

    använts.

    MOOCar karakteriseras av att de skall vara tillgängliga för alla, därav valdes användarvänlig

    och kostnadsfri plattform och programvara. På grund av att en direktuppspelning

    inom MOOCar ska kunna stödja ett stort deltagarantal gavs kursdeltagarna

    enbart möjlighet att kommunicera via chatt medan läraren kunde kommunicera via

    såväl chatt som ljud och video. Studien visade att såväl kursdeltagare som lärarna

    upplevde direktuppspelning som ett givande komplement till de kommunikationsmöjligheter

    som redan ges i MOOCar med självstyrd studietakt men att läraren bär

    ett stort ansvar i att möjliggöra de sociala interaktionerna som direktuppspelning

    ger möjlighet till. Direktuppspelning visades även ge en personlig kontakt som kan

    hjälpa minimera känslan av att vara isolerad. Baserat på studien utformades en manual

    för att underlätta implementeringen för lärare i framtida kurser.

    Blockchain and Entrepreneurial Value Creation in the Textile Industry2018Independent thesis Advanced level (degree of Master (Two Years)), 10 poäng / 15 hpOppgave
    Abstract [en]

    This thesis examines a process of innovation within a Swedish early-stage start-up company in the textile industry. The thesis describes and analyzes the case company’s intentions to create entrepreneurial value by reconfiguring its supply chain as one of its resources. Theories of dynamic capabilities, entrepreneurial value creation and supply chain management are applied for analysis of the case company’s process of investigating how Blockchain technology can be applied to the company’s supply chain to create and enhance value for the company, its customers and suppliers. Topics of digitalization, Blockchain technology, supply chain management, entrepreneurial value creation and dynamic capabilities are covered as part of the discourse.

    The work in this thesis is qualitative and explorative and based on the study of one case company and its quest for creating entrepreneurial value by reconfiguring its supply chain. The study explores several potential ways for how entrepreneurial value can be created through process of innovation, e.g., by the application of Blockchain to a company’s supply chain.

    Although Blockchain has potential to create entrepreneurial value for the case company, it is not possible to predict if the benefits outweigh the costs, if the project is feasible in practice, if it is suitable for one company to undertake the project on its own or if collaboration and alliances are the way forward.

    Fundamental-mode fiber-to-fiber coupling at high-power2009Inngår i: Solid State Lasers XVIII: Technology and Devices, SPIE - International Society for Optical Engineering, 2009, s. 71930F-Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Fiber-to-fiber coupling between two different fibers is a state of the art technology. Products are available on the market where multimode fibers can be coupled with very low power loss, at very high powers (multi-kilowatt). We have, however, always been forced to accept a certain loss in beam quality, manifesting as an increase in the Beam Parameter Product (BPP). In fundamental-mode fiber-to-fiber coupling no beam quality is lost. We instead expect to have a certain power loss in the coupling. This paper addresses the problems in free-space fundamental-mode fiber-to-fiber coupling, including theoretical estimations of expected power loss, estimated demands on the stability of the optics as well as measured values on a fundamental mode fiber-to-fiber coupler. The theoretical calculations of the sensitivity of the coupling efficiency due to radial misalignment and defocus (longitudinal displacement) have been confirmed experimentally. Experimental results at 100 W laser power include 88% coupling efficiency using a large mode area fiber with mode-field diameter (MFD) of 18 μm and 75 % coupling efficiency using a single-mode fiber with MFD of 6.4 μm.

    DRM – Intrusion or Solution?2005Inngår i: Innovation and the knowledge economy / [ed] Cunningham, P., Cunningham, M., Amsterdam: IOS Press, 2005, s. 925-933Konferansepaper (Fagfellevurdert)
    Abstract [en]

    DRM could be the solution to the content industry’s P2P dilemma, but content owners’ desire to monitor and control the consumer’s use of content can be perceived as an intrusion of privacy. High control makes consumers less active and low control invites them to experiment and to gain experience. Digital music files can easily be spread. Therefore legal services prefer keeping control over the music. This study reveals that consumers are one step ahead of the content industry, finding ways to circumvent protection and laws, and that the music industry is awaiting the "right" DRM business model. Online Music sellers basically rely on B2C DRM business models, but attempts have been made with C2C models, using consumers as distributors, and ISP models, where ISPs pay to collecting societies for all file trans-fers of copyrighted material in their networks. Future models include licensing mod-els, micro models, and no copyright at all.

    Experimental Techniques for Aeroacoustics in Low Mach Number Confined Flows: Keynote Paper2011Inngår i: Proceedings of the International Conference on Mechanical Engineering 2011(ICME2011) 18-20 December 2011, Dhaka, Bangladesh, ICME , 2011Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Measurement of plane wave acoustic transmission properties, so called two-port data, of flow duct components is important in many applications such as in the development of mufflers for IC-engines. Measurement of two-port data is difficult when the flow velocity in the measurement duct is high because of the flow noise contamination of the measured pressure signals. The wall mounted pressure transducers normally used will pick up unwanted flow noise mainly in the form of turbulent pressure fluctuations. The problem is then obtaining a signal-to- noise ratio high enough for quality measurements. Techniques to improve acoustic two-port determination have been developed in this paper, including test rig design, signal processing techniques and over-determination.

    Towards a framework for design and evaluation of mixed initiative systems: Considering movement as a modality2009Inngår i: IHRCMICA-2009 Improving Human-Robot Communication with Mixed-Initiative and Context-Awareness: Proceedings of the Workshop on Improving Human-Robot Communication with Mixed-Initiative and Context-Awareness co-located with Ro-Man 2009, 2009Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We propose a framework for design and evaluation of mixed initiative robotic systems, focusing mostly on the robot initiative in the case of a robotic shopping trolley. Throughout, we consider the implications of the movement modality in the robot initiative and the communication that follows it. We illustrate our considerations with our experience in designing and evaluating mixed-initiative human-robot communication with a mock-up robot and subsequently an actual robot platform.

    Declarative interaction towards evolutionary user interface prototyping2018Inngår i: 16th IFIP TC13 International Conference on Human-Computer Interaction, INTERACT 2017, Springer, 2018, Vol. 10774, s. 83-90Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper examines the potential of describing interactive systems in a declarative manner with concepts familiar to both developers and designers. Such declarative interaction descriptions will enable evolutionary prototyping processes. This new type of design and development processes that can emerge with declarative interaction is described along with benefits for human-centred system design. A few challenges are raised for future research in this area.

    Monte Carlo Simulation to Evaluate Factors Affecting Imaging Performances of Compact Scintillation Gamma Camara2016Inngår i: 2016 IEEE NUCLEAR SCIENCE SYMPOSIUM, MEDICAL IMAGING CONFERENCE AND ROOM-TEMPERATURE SEMICONDUCTOR DETECTOR WORKSHOP (NSS/MIC/RTSD), IEEE , 2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In recent years, a new generation of compact gamma cameras, based on monolithic scintillation crystals, has become increasingly widespread. The main advantages of small FoV gamma cameras with respect to the standard ones are high portability, low cost and low weight, allowing several clinical applications, from scintimammography to intraoperative tumor localization. In gamma cameras based on continuous scintillation crystals, intrinsic Spatial Resolution (SR) is mainly affected by two factors: scintillation light collection efficiency and overall crystal thickness. The first affects the counting statistics, the latter impacts on the light distribution width. To fully investigate the potentiality of these devices we took advantage of Monte Carlo simulations as a valuable tool to physically characterize the imaging systems and to establish a priori reference values. GEANT4 toolkit allows to completely describe the phenomenon of light emission and propagation through the media, providing control to all second-order factors existing in real systems. Results show clearly that SR is dependent on the number of photoelectrons produced and on the light spread. Furthermore, the role of refractive index has been unambiguously identified as an important factor affecting light collection and consequently SR.

    Life tracking och träningsmotivationvia smartphone2013Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Loggning av vardagliga moment såsom träning är något som brukar kallas för

    lifetracking.

    Sedan 1980-talet har övervikt bland 16-29 åringar dubblerats i

    Sverige, på grund av sämre matvanor och minskad fysisk aktivitet. Samtidigt har

    många i den här åldersgruppen tillgång till smartphones, samt stor teknikvana.

    Smartphones ger möjlighet till

    lifetracking, vilket kan utnyttjas för att motverka

    ohälsan med hjälp av motivationshöjande träningsapplikationer.

    Syftet med undersökningen var att undersöka motivationsnivåer hos redan aktiva

    motionärer. Vi har kopplat egenskaper hos fyra olika

    lifetracking-hjälpmedel för

    att avgöra vilka egenskaper som är mest effektiva för att påverka

    träningsmotivationen positivt. Tjugo personer använde hjälpmedlen under en

    treveckorsperiod, och deras användningsmönster noterades och analyserades.

    Resultatet visar att loggning är ett effektivt sätt för att öka motivationen.

    Användarnas åsikter och förändringar i motivation har sedan legat till grunden för

    en träningsapplikations-prototyp.

    Quantum metrology at the limit with extremal Majorana constellations2017Inngår i: Operator Theory: Advances and Applications, ISSN 1004-4469, E-ISSN 2334-2536, Vol. 4, nr 11, s. 1429-1432Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Quantum metrology allows for a tremendous boost in the accuracy of measurement of diverse physical parameters. The estimation of a rotation constitutes a remarkable example of this quantum-enhanced precision. The recently introduced Kings of Quantumness are especially germane for this task when the rotation axis is unknown, as they have a sensitivity independent of that axis and they achieve a Heisenberg-limit scaling. Here, we report the experimental realization of these states by generating up to 21-dimensional orbital angular momentum states of single photons, and confirm their high metrological abilities.

    A Head-Mounted Display to Support Remote Operators of Shared Automated Vehicles2017Independent thesis Advanced level (degree of Master (Two Years)), 80 poäng / 120 hpOppgave
    Abstract [en]

    Automated driving systems will be severely challenged under the unpredictable conditions of mixed traffic. Consequently, some form of human support remains essential in the foreseeable future. This challenge is particularly true for Shared Automated Vehicles, as these vehicles will likely not include any human driver onboard. When a Shared Automated Vehicle encounters a situation it cannot handle, a remote human operator will be needed to intervene. The remote operator can help the passengers to continue their journey by resuming vehicle operations. This thesis has investigated whether using a Head-MountedDisplay in comparison to a computer display improves Situation Knowledge for remote operators of Shared Automated Vehicles. This research adopted a user-centered design approach to develop a Head-Mounted Display and computer display prototype. In one of the first studies on a Shared Automated Vehicle remote control interface, this thesis considered implicit measurements of Situation Knowledge and did not focus on performance indicators. In a userstudy, twelve participants were given the task to determine the reason why theShared Automated Vehicle had stopped based on pre-recorded driving scenarios.Strong qualitative evidence indicates that a Head-Mounted Display canprovide remote operators with improved Situation Knowledge in comparisonto computer displays. To deepen the understanding of the performance andSituation Knowledge for remote operators of Shared Automated Vehicles undervarious conditions further research is necessary. Future studies can extendknowledge by assessing different scenarios and tasks in a live remote controlsituation, and develop and evaluate additional interface elements.

    Toward an asymptotic behaviour of the ABC dynamo2015Inngår i: Europhysics letters, ISSN 0295-5075, E-ISSN 1286-4854, Vol. 110, nr 1, artikkel-id 14003Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The ABC flow was originally introduced by Arnol'd to investigate Lagrangian chaos. It soon became the prototype example to illustrate magnetic-field amplification via fast dynamo action, i.e. dynamo action exhibiting magnetic-field amplification on a typical timescale independent of the electrical resistivity of the medium. Even though this flow is the most classical example for this important class of dynamos (with application to large-scale astrophysical objects), it was recently pointed out (Bouya Ismaël and Dormy Emmanuel, Phys. Fluids, 25 (2013) 037103) that the fast dynamo nature of this flow was unclear, as the growth rate still depended on the magnetic Reynolds number at the largest values available so far . Using state-of-the-art high-performance computing, we present high-resolution simulations (up to 40963) and extend the value of Rm up to 5·105. Interestingly, even at these huge values, the growth rate of the leading eigenmode still depends on the controlling parameter and an asymptotic regime is not reached yet. We show that the maximum growth rate is a decreasing function of for the largest values of we could achieve (as anticipated in the above-mentioned paper). Slowly damped oscillations might indicate either a new mode crossing or that the system is approaching the limit of an essential spectrum.

    The personality venture capitalists look for in an entrepreneur: An artificial intelligence approach to personality analysis2018Independent thesis Advanced level (degree of Master (One Year)), 20 poäng / 30 hpOppgave
    Abstract [en]

    To date, the usual analysis of an entrepreneur personality is primarily a gut feeling of theventure capitalist and is hard to codify. This paper aims to explore in a qualitative way what itis about the characteristics and the personality of the entrepreneur that influences theinvestment made by the venture capitalists. These findings will then be used to discuss if anartificial intelligence application can be used to analyze the personality of entrepreneurs.The primary source of information for this paper is interviews with venture capitalists. Theauthors searched for similarities within the available literature on entrepreneurial personalitiesand found that the majority of the personality traits mentioned by the venture capitalist can befound in the literature.The research findings suggest that all venture capitalist value an entrepreneur that has passionfor what she is doing and has the ability to get the job done. Additionally, most of the venturecapitalist interviewed value an entrepreneur that is coachable, flexible, visionary, and is ableto communicate that vision well.Finally, based on the results, the authors proposed a framework for how an artificialintelligence system can be structured to assess personalities of entrepreneurs.

    Plasma fatty acid profile and the link to target protein expression of relevance for cardiovascular disease: a population-based study of 70-year old men and women: This master thesis project was performed at Uppsala University Department of Public Health and Caring Sciences, Clinical Nutrition and Metabolism2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Dietary fatty acids (FAs) have been extensively studied in terms of preventing cardiovascular disease (CVD) through a healthy diet. Certain FA patterns in plasma lipids have been related to increased risk to develop CVD whereas others seems to be preventative (e.g. high linoleic acid [LA], and low palmitoleic acid [16:1n-7]).However, the mechanism behind how FAs are involved in CVD remains unclear. It is believed to involve inflammation and cholesterol metabolism, conditions in which both FAs and a large variety of cardiovascular(CV) proteins are involved. The aim of this project was to investigate whether there are any linkage between plasma fatty acid patterns related to CVD and CV proteins. A cross-sectional analysis was performed in two independent population-based cohorts. The Prospective Investigation of the Vasculature in Uppsala Seniors(PIVUS) cohort was used as a discovery sample and The Prospective investigation of Obesity, Energy andMetabolism (POEM) cohort in Uppsala was used as a replicate sample. A factor analysis of FAs measured in plasma was conducted in respective cohort to identify fatty acid patterns related to CVD. Linear regressionmodels between FA patterns and 84 CV proteins measured in respective cohort (samples) were performed.The 81 proteins being found in both samples were meta-analyzed. Traditional CVD risk factors (sex, BMI,diabetes, systolic blood pressure, LDL and HDL-cholesterol and smoking) were adjusted for. Two factors(Low-LA-factor, Fatty-fish-Lipid-factor) (eigenvalue>1) built up by the same patterns of FAs in both samples and constituted of FAs previously related to CVD were disclosed. The Low-LA-factor was constituted of highloadings of palmitoleic acid (16:1n-7) and oleic acid (18:1n-9) and low loadings of linoleic acid (LA) (18:2n-6),previously recognized as a CVD risk pattern. The Fatty-fish-lipid-factor was constituted of high loading’s ofeicosapentaenoic acid (EPA) (20:5n-3) and docosahexaenoic acid (DHA) (22:6-n-3), previously recognized as cardio preventative FA pattern. In the linear regression meta-analysis, the Low-LA-factor was significantly positively related to 3 plasma proteins. The Fatty-fish-lipid-factor was significantly related negatively with 16plasma proteins and positively with one plasma protein. The majority of these CV proteins have previously been related to CVD but not connected with plasma fatty acid composition. Thus, these novel results confirmthat there are relationships between dietary FA patterns and proteins involved in CVD that potentially partially mediates the association between certain FA patterns and CVD risk. With further research oncausality between FAs and these proteins as well as potential mechanisms, these links may be used as a basisfor future and more tailored dietary strategies to prevent CVD in high-risk individuals.

    Abstract [en]

    A recently developed application of Director Musices (DM) is presented. The DM is a rule-based software tool for automatic music performance developed at the Speech Music and Hearing Dept. at the Royal Institute of Technology, Stockholm. It is written in Common Lisp and is available both for Windows and Macintosh. It is demonstrated that particular combinations of rules defined in the DM can be used for synthesizing performances that differ in emotional quality. Different performances of two pieces of music were synthesized so as to elicit listeners’ associations to six different emotions (fear, anger, happiness, sadness, tenderness, and solemnity). Performance rules and their parameters were selected so as to match previous findings about emotional aspects of music performance. Variations of the performance variables IOI (Inter-Onset Interval), OOI (Offset-Onset Interval) and L (Sound Level) are presented for each rule-setup. In a forced-choice listening test 20 listeners were asked to classify the performances with respect to emotions. The results showed that the listeners, with very few exceptions, recognized the intended emotions correctly. This shows that a proper selection of rules and rule parameters in DM can indeed produce a wide variety of meaningful, emotional performances, even extending the scope of the original rule definition

    The Radio Baton as configurable musical instrument and controller2003Inngår i: Proceedings of SMAC 2003, Stockholm Music Acoustics Conference, 2003, Vol. 2, s. 689-691Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The Max Mathews’ Radio Baton (RB) has usually been applied as an orchestra conducting system, as interactive music composition controller using typical percussionist gestures, and as a controller for sound synthesis models. In the framework of the Sounding Object EU founded project, the RB has found new applications scenarios. Three applications were based on this controller. This was achieved by changing the gesture controls. Instead of the de- fault batons, a new radio transmitter based on a thimble that fits the fingertips was developed. This new transmitter allows musicians’ interaction based on hand gestures and it can also fit different devices. The RB and the thimble-based transmitter are used for the control of apd model implementing DJ scratching techniques. This new configuration of the RB allows DJs a direct control of sampled sounds maintaining hand gestures similar to those used on vinyl. In another application the sound model of a bodhran was controlled with a traditional playing approach. In this case the RB can be controlled with a traditional bodhran double beater with one thimble radio transmitter fitted at each end. This allows detection of the beater position on the RB surface, the surface corresponding to the membrane of the bodhran in the sound model. In a third application the thimble controller was used to move a virtual ball rolling along the elastic surface of a box placed over the receiving antennae of the RB.
