    Profiling and accelerating commodity NFV service chains with SCC2017Inngår i: Journal of Systems and Software, ISSN 0164-1212, E-ISSN 1873-1228, Vol. 127, nr C, s. 12-27Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Recent approaches to network functions virtualization (NFV) have shown that commodity network stacks and drivers struggle to keep up with increasing hardware speed. Despite this, popular cloud networking services still rely on commodity operating systems (OSs) and device drivers.

     

    Taking into account the hardware underlying of commodity servers, we built an NFV profiler that tracks the movement of packets across the system’s memory hierarchy by collecting key hardware and OS-level performance counters.

     

    Leveraging the profiler’s data, our Service Chain Coordinator’s (SCC) runtime accelerates user-space NFV service chains, based on commodity drivers. To do so, SCC combines multiplexing of system calls with scheduling strategies, taking time, priority, and processing load into account.

     

    By granting longer time quanta to chained network functions (NFs), combined with I/O multiplexing, SCC reduces unnecessary scheduling and I/O overheads, resulting in three-fold latency reduction due to cache and main memory utilization improvements. More importantly, SCC reduces the latency variance of NFV service chains by up to 40x compared to standard FastClick chains by making the average case for an NFV chain to perform as well as the best case. These improvements are possible because of our profiler’s accuracy.

    The design of flexible and efficient future mobile communication systems is a major challenge. The Walkstation Project involves researchers from different areas in order to find a solution via a global system approach. An important task is the investigation of new digital, highly integrated radio interfaces with low cost, small size and low power consumption based on direct sequence CDMA. The simplicity of the design of both the analog and digital parts will allow low power operation and small area in an eventual BiCMOS implementation.

    Wireless LAN Access Points Uplink and Downlink Delays: Packet Service-Time Comparison2002Inngår i: Proceedings of 16th Nordic Teletraffic Seminar, 2002, 2002, s. 253-264Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Wireless LAN access points are very important connecting nodes transferring traffic between two media in opposite directions. Hence the performance of the wireless LAN access point should be looked upon from two different reference points: uplink (from WLAN to Ethernet) and Downlink (from Ethernet to WLAN). This paper builds on our previous modeling of the wireless access point as a single server, FIFO, queuing system to analyze the service times in both directions. The previous analysis showed that the average service time is a function of payload. Measurements have revealed that the uplink service time is much smaller than the downlink service time for the same payload. In this paper, we investigate the absolute value of the difference between the uplink and downlink service-times. We refer to the absolute value of the difference in time between uplink and downlink as the UDC, or the"Uplink-Downlink Contrast". Results show that as the packet size increases, the UDC either decreases or increases monotonically depending on the brand of the access point. For a decreasing UDC, the absolute value of the difference between the uplink and downlinkservice-times decreases, hence the UDC is convergent. Similarly, the UDC is divergent if it increases with increasing packet size. These results can be used to select a WLAN accesspoint given the size of packets transmitted by an application or multiple applications over a Local Area Network.

    MobiCom poster: wireless LAN access points as queuing systems: performance analysis and service time2003Inngår i: ACM SIGMOBILE Mobile Computing and Communications Review, ISSN 1559-1662, Vol. 7, nr 1, s. 28-30Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Since the approval of the IEEE 802.11b by the IEEE in 1999, the demand for WLAN equipment and networks has been growing quickly. We present a queuing model of wireless LAN (WLAN) access points (APs) for IEEE 802.11b. We use experimentation to obtain the characteristic parameters of our analytic model. The model can be used to compare the performance of different WLAN APs as well as the QoS of different applications in the presence of an AP. We focus on the delay introduced by an AP. The major observations are that the delay to serve a packet going from the WLAN medium to the wired medium (on the uplink) is less than the delay to serve a packet, with identical payload, but travelling from the wired medium to the WLAN medium (on the downlink). A key result is an analytic solution showing that the average service time of a packet is a strictly increasing function of payload.

    Wireless LAN Access Points as a Queuing System2002Inngår i: Proceedings of The Communications and Computer Networks 2002 Conference (CCN 2002), 2002, s. 463-468Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper presents a research study of wireless LAN access points for IEEE 802.11b, where we seek to model the access point as a queuing system. The model can be used to compare performance metrics of different wireless LAN access points and to investigate the QoS of specific applications in the presence of a wireless LAN access point. In this paper, we focus on two parameters: the delay introduced by a wireless LAN access point and the average service time required to serve a packet passing through an access point. A major result is an analytic solution for the average service time of a packet in relationship to payload.

    Distributed Context Data Management2005Inngår i: CEUR Workshop Proceedings, 2005Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We argue that general context data distribution can be achieved by establishing a network of context managers. The context managers have a uniform core which is surrounded by the appropriate functionality to make it deployable in applications, user and organizational infrastructure, and on top of sensors. When access to the context manager is mediated and policed, we say that it is a context service, a publicly recognisable, addressable and tangible entity. Clients that wish to consult the context manager for updated context information, must turn to the service interface where they may face rejection for reasons of security, personal integrity or workload.

    Do Small-Mass Neutrinos Participate in Gauge Transformations?2016Inngår i: Advances in High Energy Physics, ISSN 1687-7357, E-ISSN 1687-7365, s. 1-7, artikkel-id 1847620Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Neutrino oscillation experiments presently suggest that neutrinos have a small but finite mass. If neutrinos have mass, there should be a Lorentz frame in which they can be brought to rest. This paper discusses how Wigner’s little groups can be used to distinguish between massive and massless particles. We derive a representation of the SL(2,c) group which separates out the two sets of spinors: one set is gauge dependent and the other set is gauge invariant and represents polarized neutrinos. We show that a similar calculation can be done for the Dirac equation. In the large-momentum/zero-mass limit, the Dirac spinors can be separated into large and small components. The large components are gauge invariant, while the small components are not. These small components represent spin-1/2 non-zero-mass particles. If we renormalize the large components, these gauge invariant spinors represent the polarization of neutrinos. Massive neutrinos cannot be invariant under gauge transformations.

    Evaluation of polynomial image deformation for matching of 3D-abdominal MR-images using anatomical landmarks and for atlas construction1998Inngår i: 1998 IEEE Nuclear Science Symposium Conference Record. 1998, Toronto, Ont., Canada: IEEE , 1998, s. 2050-2052Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The aim of this study is to compare and evaluate the potential usability of linear and non-linear (polynomial) 3D-warping for constructing an atlas by matching abdominal MR-images from a number of different individuals using manually picked anatomical landmarks. The significance of this study lies in the fact that it illustrates the potential to use polynomial matching at a local or organ level. This is a necessary requirement for constructing an atlas and for fine intra-patient image matching and fusion. Finally 3D-image warping using anatomical landmark for inter-patient intra-modality image co-registration and fusion was found to be a very powerful and robust method. Additionally it can be used for intra-patient inter-modality image matching.

    Evaluation of polynomial image deformation using anatomical landmarks for matching of 3D-abdominal MR-images and for atlas construction1999Inngår i: IEEE TRANSACTIONS ON NUCLEAR SCIENCE, ISSN 0018-9499, Vol. 46, nr 4, s. 1110-1113Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    While a variety of different deformation algorithms have been implemented for matching of skull, few attempts in matching areas in abdomen have been reported. In this study the authors evaluate the usability of first and second order polynomial 3D-warping for this purpose. They match abdominal MR-images from different individuals using manually picked anatomical landmarks. Generation of transformation coefficients was done through a linear regression technique that employs a least square fit using the reference landmarks. The landmarks were picked in a predefined order, well spread over the entire data set, by a radiologist. The image resampling was done using linear interpolation and the evaluation was performed visually as well as by calculating the cross correlation and the normalized least squared error between the original image and the transformed image. The authors' preliminary results reveal that the second order polynomial transformation using landmarks is a robust and efficient method. It is also superior to the second order one, for image deformation in the abdominal region and it may be used in atlas generation as well as in multimodality image co-registration and fusion.

    Abstract [en]

    Today, mobility of portable computers and workstations is not transparent to users. They adjust to reduced services as long as they have no connection to a supporting infrastructure. The goal of the Walkstation project is to realize a user transparent mobile IP router (MINT) for wireless links (infrared and radio) operating at 1-10 Mbit/sec. For the study of user behavior and system characteristics a campus wide testbed (ERIC) with 50-100 stations is planned to demonstrate the new solutions found in the Walkstation II project.

    Fusing of immunoscintigraphy SPECT with CT or MRI for improved multimodality image interpretation1992Inngår i: Engineering in Medicine and Biology Society, 1992 14th Annual International Conference of the IEEE, IEEE , 1992, Vol. 5, s. 1805-1806Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Correlation of PET or SPECT functional with CT or MRI anatomic transaxial images often enhances the information available on these studies. Careful registra­tion of images from two types of studies may be used to identify a structure containing to a PET or SPECT abnormality or to evaluate the functional or metabolic characteristics of an abnormal or normal structure. CTSPECT or PET image registration has been applied to brain imaging for metabolic and cerebral perfusion studies [1–3], more recently, to Ga-67 imaging of the chest [4], as well as to CT-SPECT correlation in cancer patients undergoing immunoscintigraphy [5–7]. We have applied an image registration technique to correlate CT or MRI of the abdomen and chest with SPECT images obtained after the administration of tumor-directed radiolabeled monoclonal antibodies. Correlation of PET or SPECT functional with CT or MRI anatomic transaxial images often enhances the information available on these studies. Careful registration of images from two types of studies may be used to identify a structure containing to a PET or SPECT abnormality or to evaluate the functional or metabolic characteristics of an attempt to improve our interpretation of these imaging studies.

    CT-SPECT fusion to correlate radiolabeled monoclonal antibody uptake with abdominal CT findings1989Inngår i: Radiology, ISSN 0033-8419, E-ISSN 1527-1315, Vol. 172, nr 3, s. 861-865Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    To enhance the information provided by computed tomography {(CT)} and single photon emission computed tomography {(SPECT)} performed with radiolabeled, anti-carcinoembryonic antigen monoclonal antibody {(MoAb)}, the authors performed fusion of these types of images from eight subjects with suspected colorectal adenocarcinoma. Section thickness and pixel size of the two studies were matched, coordinates of corresponding points from each study were identified, and {CT} sections were translated, rotated, and reprojected to match the corresponding {SPECT} scans. The {CT-SPECT} fusion enabled identification of anatomic sites of tumor-specific {MoAb} accumulation in four cases, showed non-specific {MoAb} accumulation in two, and helped confirm information only suggested by the two studies separately in one.

    Unmasking true signal/tumor information from ProstaScint scans2004Inngår i: MEDICAL IMAGING 2004: IMAGE PROCESSING, PTS 1-3 / [ed] Fitzpatrick, JM; Sonka, M, SPIE - International Society for Optical Engineering, 2004, Vol. 5370, s. 1980-1990Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Purpose: Improve tumor localization in In-111 ProstaScint SPECT scans through improved reconstruction and identification/removal of non-specific blood pool volumes using simultaneously acquired Tc-99m tagged red blood cell (RBC) SPECT scans. Methods: We chose 30 patients with a history of prostate cancer who had undergone CT/MR and simultaneous Tc-99m RBC/In-111 ProstaScint SPECT scans due to rising PSA. To estimate the impact of reconstruction methods on anatomic definition and artifacts, SPECT volume data sets were reconstructed using ordered set-expectation maximization (OS-EM) with varying numbers of iterations and subsets, and these were compared against each other and against standard filtered back projection (FBP) reconstruction. Non-blood pool bladder activity in the Tc-99m scans was suppressed prior to subtraction from the In-111 scans by using an averaging algorithm within an ellipsoid volume encompassing the bladder. Outside the ellipsoid volume, Tc-99m voxel values were subtracted from the corresponding In-111 voxels after normalization of the data sets based on peak activity within the descending aorta. Results: OS-EM reconstruction using 3 iterations and 45 subsets showed improved representation of anatomy compared with FBP. Bladder suppression reduced artifacts in the prostate bed. The subtraction method reduced the blood pool signal, confirmed visually by superimposition with matched CT/MR scans. Conclusions: OS-EM reconstruction together with bladder suppression and subtraction of the blood pool may help improve the specificity of ProstaScint SPECT interpretation and increase its utility in radiation therapy treatment planning.

    Dynamic PET visualization of bone remodeling using NaF-182015Rapport (Annet vitenskapelig)
    Abstract [en]

    Positron emission tomography (PET) studies acquired in list mode offer the opportunity to provide a cine loop showing the dynamics of 18F- PET uptake, giving a visualization of regional bone remodeling. The focus of this report is a group of patients treated with Taylor spatial frames (TSF). The studies were acquired for a period of 45 minutes and saved in list mode. The list was decoded and subsequently segmented into time intervals of one minute each. For each time interval a sinogram was generated from which volumes of one minute each were reconstructed. Slices projected from these volumes could then be displayed as a dynamic loop superimposed on the corresponding computed tomography (CT) slice in order to visualize the 18F- uptake insitu. It was indicated that this technique has the potential of becoming an additional technique to that of using static volumes and SUV values only.

    As the list mode data was decoded it also offered a method to evaluate the potential decrease in injected activity by eliminating every Nth event from the list before reconstructing the 45 minute volume. This was done and the indication was that the injected activity and hence the effective dose to the patient can be decreased. However, in this work, this was not proven clinically.

    The open source STIR software was used to reconstruct volumes from sinograms to enable an unlimited access to reconstructing volumes without disturbing the daily routine at the clinic. The data was acquired on a clinical Siemens Medical Solutions Biograph 64 TruePoint TrueV, PET/CT scanner situated at the Nuclear Medicine Department at the Karolinska University Hospital in Solna. This scanner was not supported by the STIR software, hence the data collected by the Siemens PET/CT scanner was translated so that 3D reconstructions could be computed using the STIR tools. The reconstructions made in STIR resulted in volumes of sufficient visual quality, but not as good as those reconstructed by the scanner itself. Further optimization in STIR was left for future work.

    According to the physicians who treat these patients, dynamic visualization was of sufficient interest to continue to develop and optimize this method. The cine loops that were presented to the physicians were made from JPEG slices produced from the one minute volumes and put together as GIF files. It was also possible to vary the reconstruction time (from uniformly one minute) as well as the presentation rate in the cine loop, but this was left for future work. Ultimately, the cine loop will be implemented in the locally developed software tool.

    A LISP Compiler for the DADO Parallel Computer.1985Rapport (Annet vitenskapelig)
    Abstract [en]

    This describes a LISP implementation for the Intel MCS-51 family of microprocessors, the processor used by the DADO parallel computer. This LISP IS the implementation language for the high-level parallel LISP (PPSL). It is based upon the Portable Standard Lisp (PSL) of the University of Utah. By writing PPSL in PSL we have achieved a significant degree of portability.

    A mobile-floating agent scheme for wireless distributed computing1995Inngår i: IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, PIMRC, IEEE , 1995, s. 100-104Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper presents a novel mobile floating (MF) agent scheme for supporting global distributed mobile computing. The principal contribution of this paper is to innovatively apply virtual memory concepts to mobile systems by deploying MF-agents to decouple the service and resource from the underlying network and move around following or proceeding their mobile users. The MF-agents maintain data structures associated with a mobile user. By combining the mobile-floating agent functionality with a predictive mobility management algorithm, services and user data may be pre-connected and pre-assigned at the locations or cells to which the user is moving. Thus, the user can immediately receive services of maintain their data structures with virtually the same efficiency as at the previous location.

    A class of mobile motion prediction algorithms for wireless mobile computing and communications1996Inngår i: Mobile Networks and Applications, ISSN 1383-469X, Vol. 1, nr 2, s. 113-121Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper describes a class of novel mobile motion prediction algorithms for supporting global mobile data accessing. Traditionally, mobility and routing management includes functions to passively keep track of the location of the users/terminals and to maintain connections to the terminals belonging to the system. To maintain uninterrupted high-quality service for distributed applications, it is important that a mobile system be more intelligent and can anticipate the change of the location of its user. We propose an aggressive mobility and routing management scheme, called predictive mobility management. A class of mobile motion prediction algorithms predicts the future location of a mobile user according to the user's movement history, i.e., previous movement patterns. By combining this scheme with mobility agent functions, the service and user routing data are actually pre-connected and pre-assigned at the locations to which the user is moving. Thus, the user can immediately receive service or data with virtually the same efficiency as at the previous location, i.e., without encountering a large "data structure handover" delay before service or data is available.

    A Mobility-Aware Dynamic Database Caching Scheme for Wireless Mobile Computing and Communications1996Inngår i: Databases and Mobile Computing / [ed] Daniel Barbara, Ravi Jain, and Narayanan Krishnakuma, Kluwer , 1996, s. 69-86Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [en]

    This paper describes a mobility-aware dynamic database caching scheme for wireless mobile computing and communications. A mobile-floating agent scheme is proposed, in which caching techniques are cognizant of the mobile nature of mobile users and the location-sensitive nature of mobile systems. The mobile-floating agent maintains a second class cache in the fixed network and employs Barbara’s “invalidation reports broadcasting” cache consistency strategies to maintain a dynamic cache consistent with the first class cache in the mobile client. The “invalidation reports broadcasting” scheme is combined with knowledge of the mobility behavior of each individual mobile user and broadcasts of invalidation reports only occur within the user’s mobility area. The evaluation results show that, for a large system (200 cells), this scheme can reduce the system cost by more than 87%, for even highly mobile users, compared with a fully replicated database system.

Traditionally, mobility management includes functions to passively keep track of the location of the users/terminals and to maintain connections to the terminals belonging to the system. To make intelligent mobile-aware applications, it is important that a mobile terminal/system be more intelligent and can anticipate the change of the location of its user. We propose an aggressive mobility management scheme, called predictive mobility management. A mobile motion prediction algorithm predicts the “future” location of a mobile user according to the user's movement history, i.e., previous movement patterns. By combining the predictive mobility management algorithm with a mobility agent scheme, the service and user data structure can be actually pre-connected and pre-assigned at the locations to which the user is moving. Thus, the user can immediately receive service or data with virtually the same efficiency as at the previous location. Simulations show that the prediction efficiency of the proposed algorithm is about 95%.

    Efficient mobility management support for wireless data services1995Inngår i: IEEE 45th Vehicular Technology Conference (VTC), IEEE , 1995, s. 902-906Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The paper describes a mobile data network architecture with a novel predictive mobility management algorithm to support global mobile data accessing. The concept of a mobile distributed system platform with mobile-floating agents is proposed to support service and resource mobility, that is, to distribute network services and resources closer to mobile users. Furthermore, by combining the predictive mobility management algorithm with mobile-floating agent functions, the services and user data are generally pre-connected and pre-assigned at the locations to which the user is moving. Thus, the user can immediately receive services and/or data with essentially the same efficiency as at the prior location.

    Abstract [en]

    This paper examines the feasibility and performance benefits of the introduction of the mobile-floating agent scheme in a mobile system. The principal contribution of this paper is to innovatively apply virtual memory concepts to mobile systems by deploying mobile-floating agents who de-couple services and resources from the underlying network and allow them to move around following their mobile users. The concept of mobile-floating agent with the notion of service mobility, service pre-assignment and resource pre-arrangement is evaluated. Detailed analysis and evaluation of these scheme in terms of latency reduction and increased system overhead versus mobility density with three different assignment algorithms are given. The performance results clearly indicate the feasibility and the performance gain of the proposed mobile-floating agent scheme.

    Can Spatiotemporal Fluoride (18F-ˆ’) Uptake be Used to Assess Bone Formation in the Tibia?: A Longitudinal Study Using PET/CT2017Inngår i: Clinical Orthopaedics and Related Research, ISSN 0009-921X, E-ISSN 1528-1132, Vol. 475, nr 5, s. 1486-1498Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    When a bone is broken for any reason, it is important for the orthopaedic surgeon to know how bone healing is progressing. There has been resurgence in the use of the fluoride (18F-ˆ’) ion to evaluate various bone conditions. This has been made possible by availability of positron emission tomography (PET)/CT hybrid scanners together with cyclotrons. Absorbed on the bone surface from blood flow, 18F-ˆ’ attaches to the osteoblasts in cancellous bone and acts as a pharmacokinetic agent, which reflects the local physiologic activity of bone. This is important because it shows bone formation indicating that the bone is healing or no bone formation indicating no healing. As 18F-ˆ’ is extracted from blood in proportion to blood flow and bone formation, it thus enables determination of bone healing progress.

    Using PET/CT Bone Scan Dynamic Data to Evaluate Tibia Remodeling When a Taylor Spatial Frame Is Used: Short and Longer Term Differences2015Inngår i: BioMed Research International, ISSN 2314-6133, E-ISSN 2314-6141, Vol. 2015, s. 1-11, artikkel-id 574705Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Eighteen consecutive patients, treated with a Taylor Spatial Frame for complex tibia conditions, gave their informed consentto undergo Na18F− PET/CT bone scans. We present a Patlak-like analysis utilizing an approximated blood time-activity curveeliminating the need for blood aliquots. Additionally, standardized uptake values (SUV) derived from dynamic acquisitions werecompared to this Patlak-like approach. Spherical volumes of interest (VOIs) were drawn to include broken bone, other (normal)bone, and muscle. The SUV𝑚(𝑡) (𝑚 = max, mean) and a series of slopes were computed as (SUV𝑚(𝑡𝑖) − SUV𝑚(𝑡𝑗))/(𝑡𝑖 − 𝑡𝑗), forpairs of time values 𝑡𝑖 and 𝑡𝑗. A Patlak-like analysis was performed for the same time values by computing ((VOI𝑝(𝑡𝑖)/VOI𝑒(𝑡𝑖)) −(VOI𝑝(𝑡𝑗)/VOI𝑒(𝑡𝑗)))/(𝑡𝑖−𝑡𝑗), where p = broken bone, other bone, andmuscle and e = expected activity in aVOI. Paired comparisonsbetween Patlak-like and SUV𝑚 slopes showed good agreement by both linear regression and correlation coefficient analysis(𝑟 = 84%, 𝑟𝑠 = 78%-SUVmax, 𝑟 = 92%, and 𝑟𝑠 = 91%-SUVmean), suggesting static scans could substitute for dynamic studies.Patlak-like slope differences of 0.1 min−1 or greater between examinations and SUVmax differences of ∼5 usually indicated goodremodeling progress, while negative Patlak-like slope differences of −0.06 min−1 usually indicated poor remodeling progress in thiscohort.

    Can Na18F PET/CT Be Used to Study Bone Remodeling in the Tibia When Patients Are Being Treated with a Taylor Spatial Frame?2014Inngår i: Scientific World Journal, ISSN 1537-744X, E-ISSN 1537-744X, Vol. 2014, s. 1-9Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Monitoring and quantifying bone remodeling are of interest, for example, in correction osteotomies, delayed fracture healing pseudarthrosis, bone lengthening, and other instances. Seven patients who had operations to attach an Ilizarov-derived Taylor Spatial Frame to the tibia gave informed consent. Each patient was examined by (NaF)-F-18 PET/CT twice, at approximately six weeks and three months after the operation. A validated software tool was used for the following processing steps. The first and second CT volumes were aligned in 3D and the respective PET volumes were aligned accordingly. In the first PET volume spherical volumes of interest (VOIs) were delineated for the crural fracture and normal bone and transferred to the second PET volume for SUVmax evaluation. This method potentially provides clinical insight into questions such as, when has the bone remodeling progressed well enough to safely remove the TSF? and when is intervention required, in a timelier manner than current methods? For example, in two patients who completed treatment, the SUVmax between the first and second PET/CT examination decreased by 42% and 13%, respectively. Further studies in a larger patient population are needed to verify these preliminary results by correlating regional (NaF)-F-18 PET measurements to clinical and radiological findings.

    Preliminary Results of Studying Bone Growth Using NaF-18 in Patients with aTaylor Spatial Frame (TSF)2013Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We were able to see the difference in bone activity ofdifferent parts of the leg over the course of a patient’s therapy. In one patient, we detected at 52 days that the fibula had an SUVmax of 66 while the tibia had an SUVmax of 14, indicating that the fibula was healing much faster than the tibia. The surgeon had to intervene, re-breaking and distracting the fibula. At 94days after the initial surgery, both bones had a more comparable activity (with an SUVmax of 37 and 24 respectively). This study has lead to the use of PET/CT imaging to assess the early clinical state of the bone remodelling process.

    A Graphical Workstation and Programming Environment for Data-Driven Computation1983Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    This dissertation reports on the development of a prototype programming environment for a graphical programming language to support a data-driven style of computation. Emphasis is on the need for tools to assist in the development of nontrivial graphical programs. Within the scope of programming languages there has been a lot of criticism that the current languages force an unnatural form for solutions, which is difficult to read, and even harder to verify, debug, maintain, and modify. One of the major "culprits" for all of these problems is felt to be side effects; thus there have been several proposals to create functional languages. One class of functional solutions which has received an increasing amount of interest is the area of data flow languages. In order to evaluate these alternate programming methodologies nontrivial programs need to be developed using such a methodology. This work grew out of an interest in providing a programming environment to support the development of very large programs in GPL and to find out what aspects of a programming environment would be substantially different for a graphical language which employs a data-driven computational model.
