    10 Years of research on debugging concurrent and multicore software: a systematic mapping study2017In: Software quality journal, ISSN 0963-9314, E-ISSN 1573-1367, Vol. 25, no 1, p. 49-82Article in journal (Refereed)
    Abstract [en]

    Debugging – the process of identifying, localizing and fixing bugs – is a key activity in software development. Due to issues such as non-determinism and difficulties of reproducing failures, debugging concurrent software is significantly more challenging than debugging sequential software. A number of methods, models and tools for debugging concurrent and multicore software have been proposed, but the body of work partially lacks a common terminology and a more recent view of the problems to solve. This suggests the need for a classification, and an up-to-date comprehensive overview of the area. 

    This paper presents the results of a systematic mapping study in the field of debugging of concurrent and multicore software in the last decade (2005– 2014). The study is guided by two objectives: (1) to summarize the recent publication trends and (2) to clarify current research gaps in the field.

    Through a multi-stage selection process, we identified 145 relevant papers. Based on these, we summarize the publication trend in the field by showing distribution of publications with respect to year , publication venues , representation of academia and industry , and active research institutes . We also identify research gaps in the field based on attributes such as types of concurrency bugs, types of debugging processes , types of research  and research contributions.

    The main observations from the study are that during the years 2005–2014: (1) there is no focal conference or venue to publish papers in this area, hence a large variety of conferences and journal venues (90) are used to publish relevant papers in this area; (2) in terms of publication contribution, academia was more active in this area than industry; (3) most publications in the field address the data race bug; (4) bug identification is the most common stage of debugging addressed by articles in the period; (5) there are six types of research approaches found, with solution proposals being the most common one; and (6) the published papers essentially focus on four different types of contributions, with ”methods” being the type most common one.

    We can further conclude that there is still quite a number of aspects that are not sufficiently covered in the field, most notably including (1) exploring correction  and fixing bugs  in terms of debugging process; (2) order violation, suspension  and starvation  in terms of concurrency bugs; (3) validation and evaluation research  in the matter of research type; (4) metric  in terms of research contribution. It is clear that the concurrent, parallel and multicore software community needs broader studies in debugging.This systematic mapping study can help direct such efforts.

    10th Anniversary Focus: From mainstream 'environmental economics' to 'sustainability economics': On the need for new thinking2008In: Journal of Environmental Monitoring, ISSN 1464-0325, E-ISSN 1464-0333, Vol. 10, no 12, p. 1467-1475Article, review/survey (Refereed)
    Abstract [en]

    Traditional ideas about science as being separate and separable from ideology have to be reconsidered. Each interpretation of sustainable development is not only scientific but at the same time ideological. For this reason our ideas about good science should also be related to normal imperatives of democracy. Mainstream neoclassical economics is specific in scientific and ideological terms. This paradigm is useful for some purposes and has played  role as a mental map in guiding us towards economic growth and other ideas about progress in society and the economy. Sustainable development, however, represents an ideological turn in our ideas about progress and it is no longer clear that neoclassical theory will be enough. Alternative perspectives in economics are being developed as part of a pluralistic strategy and the monopoly position of neoclassical economists at university departments of economics is thereby challenged. A 'political economic person' is suggested as alternative (complement) to Economic Man assumptions and a 'political economic organization' to be compared with the neoclassical profit-maximizing firm. Alternative ways of understanding markets and international trade, efficiency, decision-making, monitoring and assessment are also needed. It is argued that such an alternative mental map is useful for actors who take the challenge of sustainable development seriously.

    1+1=3 En studie om hur illustration kan användas inom matematik för barn2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis is a collaboration with Framtidens läromedel, which is a research and product development project at Mälardalen University. Studies show that the mathematics skills of Swedish students are declining. The project aims to create a teaching material based on research that can help change the trend.

     

    The project is developing several different parts. A book for students, a teacher's guide and a PowerPoint to use in the classroom. My task is to design the PowerPoint which aim to include interesting illustrations.

     

    Research shows that students understand the content of a text better if they can look at a descriptive image. The “image” can be a movie, a picture in a book or a sketch drawn by the teacher on the board to help the students to understand.

     

    The conclusion of this study is that a design should be attractive and that an image should be easy to read and to understand. This makes the recipients interested to the message being conveyed.

     

    Studies show that in mathematics and mainly geometry, children relate geometric shapes to familiar objects. I have considered this in the creation of a descriptive image showing geometric shapes placed in an everyday context.

    15 Years of CBSE Symposium: Impact onthe Research Community2012In: CBSE '12 Proceedings of the 15th ACM SIGSOFT symposium on Component Based Software Engineering, 2012, p. 61-70Conference paper (Refereed)
    Abstract [en]

    In 2012, the International Symposium on Component-based Software Engineering (CBSE) is being organized for the 15th time. This is a great opportunity to take a step back and reflect on the impact of the symposium over these 15 years. Several interesting questions immediately come to mind: What were the main topics of interest in the community? What is the maturity of the field? What is the research CBSE Symposia impact? Who are the mots involved researches and researchers centers? In order to answer these questions we have performed a systematic review of 318 papers published under CBSE. In this paper we provide answers about the impact of the event, list and categorize the most frequent topics, and give some statistical data about the event during this period.

    18,21, Piruett: En kvalitativ studie där pedagogers och elevers uppfattningar om dansmatteundervisning synliggörs2014Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien är att undersöka och synliggöra faktorer som kan påverka  dansmatteundervisnings relevans för elevers lärande i matematikämnet, detta i grundskolans tidigare år. Två kvalitativa insamlingsmetoder, i form av semistrukturerade intervjuer och observationer, har använts i undersökningen. Resultatet antyder att dansmatteundervisning kan vara relevant i och med att arbetssättet innebär en förståelseinriktad undervisning, där ett reflekterande arbetssätt med gemensamma samtal om matematiskt innehåll genomsyrar undervisningen. Att kommunikationen ökar, genom att både verbal och kinestetisk kommunikation samspelar i dansmatteundervisning, kan också bidra till att arbetssättet kan vara relevant. Pedagogens möjlighet till direkt återkoppling till elever anses som en styrka i dansmatteundervisning. De mest kritiska och avgörande faktorerna som kan påverka eller begränsa dansmatteundervisnings relevans antyder resultaten vara pedagogens ämnesspecifika kompetens, genomförande av samplanering mellan involverade pedagoger, samt tidsplaneringen med mängden avsatt tid för genomförandet av dansmatteundervisning. Dessa faktorer kan påverka eller begränsa dansmatteundervisnings relevans för elevers lärande. Slutsatser som gjorts i studien är att dansmatteundervisning är relevant för elevers lärande i matematikämnet ur aspekter som elevers möjlighet till djupinlärning, ökad kommunikation i undervisningen, ökad konceptuell undervisning, förståelseinriktad undervisning samt att elever upplever variationen som motivationshöjande. Dansmatteundervisning kan både vara inkluderande och exkluderande för elever, vilket påverkar dansmatteundervisningens relevans.

    1970-talets läseböcker i svenska för lågstadiet - speglingar  av samhället?2011Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta examensarbete undersöker genom analys innehållet i ett urval av samtida läseböcker i svenska för lågstadiet. Studiens syfte är att undersöka om, och i så fall på vilket sätt de förändringar som skedde i det svenska samhället under 1970-talet förmedlades. Det övergripande styrdokumentet för grundskolan under denna period var Läroplan för grundskolan (Lgr69). Studien innehåller även forskningsbakgrund kring läseböcker från 1970-talet samt en tillbakablick över den svenska läsebokens historia.

    Genom text- och bildanalyser av läseböcker som använts i svenskundervisning under 1970-talet visar studien att det finns övergripande likheter i deras innehåll. Dock finns det skillnader mellan böckerna vad gäller struktur, disposition och val av illustrationer. Samtliga läseböcker i studien innehåller en blandning av traditionella teman för läsinlärning, blandat med texter som speglar ett samhälle med för tiden nya värderingar och strukturer.

    Abstract [en]

    In traditional design of computer based systems some effort, say 1, is spent on the early modeling phases, and some very high effort, say 50, is spent on the later implementation and testing phases. It is the conjecture of this paper that the total effort can be substantially reduced if an increased effort, say 2, is spent on the early modeling phases. Such a shift in focus of efforts will also greatly improve the overall effects (both quality and cost-wise) of the systems dev eloped, there by leading to a better (denoted by "≻") design process. In this paper, w e specifically consider the design of safety-critical distributed real-time systems. © 2000 Springer-Verlag Berlin Heidelberg.

    200 hamburgare = minus 34 kilo: En kritisk diskursanalys av den kroppsliga hälsans konstruktion i svensk skriven nyhetsmedia2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här studien är en kritisk diskursanalys av ämnet kroppslig hälsa i skriftlig media. Syftet med studien är att undersöka hur fenomenet kroppslig hälsa framställs i skriftlig media genom språket och dess användning. Analysmodellen vi använt oss av är formulerad av Norman Fairclough och det datamaterial vi använt oss av är av empirisk karaktär och insamlat från svensk skriven media i form av både rikstäckande press och lokalpress. I studien finns även ett avsnitt där vi presenterar tidigare forskning inom ämnet hälsa och diskursanalys. Forskningen presenteras genom fem teman: biopolitik, livsstil, individens ansvar, klass och könsskillnad utifrån ett hälsoperspektiv samt experthjälp. Den teori vi utgått ifrån för studien är främst den för den kritiska diskursanalysen, vi har även använt oss av Foucaults biopolitik vilken främst ges uttryck i diskussionsdelen.  Resultatet för studien presenteras i två delar utifrån Fairclouchs analysmodell; text samt diskursiv praktik. Resultatet redogör vi för med en rad olika teman vi formulerat utifrån den analys som gjorts. De teman som vi formulerat är: hotspråk, den stratifierade hälsan, anvisningar & imperativ, superlativ, vetenskapligt språk och den reella exemplifieringen (del ett). De huvudsakliga diskurser vi funnit i materialet är: den ohälsosamma diskursen, den hälsosamma diskursen, den vetenskapliga diskursen samt den utbildande diskursen (del två).

    Abstract [en]

    A method that permits the determination of moisture content in biofuel in a fast and representative way is under development. Vie method uses radio frequency waves within the range of 310 MHz to 800 MHz and measures the reflection coefficient in samples with volume of about 0.1 m(3). The influence of sample temperature in the measurements is shown in this study. Two biofuel types were used, with moisture content varying between 31% and 63% and temperature varying between 1 degrees C and 63 degrees C. The data was evaluated with multivariate data analysis. Results show that it is not possible to identify the sample temperature as a principal component in a principal component analysis and partial least squares regression shows no correlation between temperature and the radio frequency data. For the frequency interval and the temperature range studied, it was not possible to detect any influence of sample temperature on moisture content prediction with the radio frequency method.

    Abstract [en]

    The importance of using formal methods and techniques for verification of requirements in the automotive industry has been greatly emphasized with the introduction of the new ISO26262 standard for road vehicles functional safety. The lack of support for formal modeling of requirements still represents an obstacle for the adoption of the formal methods in industry. This paper presents a case study that has been conducted in order to evaluate the difficulties inherent to the process of transforming the system requirements from their traditional written form into semi-formal notation. The case study focuses on a set of non-structured functional requirements for the Electrical and Electronic (E/E) systems inside heavy road vehicles, written in natural language, and reassesses the applicability of the extended Specification Pattern System (SPS) represented in a restricted English grammar. Correlating this experience with former studies, we observe that, as previously claimed, the concept of patterns is likely to be generally applicable for the automotive domain. Additionally, we have identified some potential difficulties in the transformation process, which were not reported by the previous studies and will be used as a basis for further research.

    32 av 51 elever tror att de kommer att lära sig ett till språk i framtiden: Varför inte redan nu?2007Independent thesis Basic level (professional degree), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Syftet med mitt arbete var att ta reda på av vilka anledningar elever i årskurs 9 har valt att inte läsa ett modernt språk utöver engelska samt vad som hade kunnat få dem att läsa ett ytterligare språk. Skillnader utifrån språkval och genus uppmärksammas. För att få svar på mina forskningsfrågor valde jag att utföra en kvantitativ surveyundersökning i enkätform. Av de elever som deltog i undersökningen var det fler som tyckte att språk var intressant, viktigt och roligt än som tyckte motsatsen. Majoriteten ansåg att språk var svårt. Eleverna ville ha mer undervisningstid i språket, mer ordkunskap och fler hörförståelseövningar samt muntliga och praktiska övningar. De ville ha mindre grammatik och färre hemuppgifter. Nästan 63% av eleverna svarade att de tror att de kommer att lära sig ett språk till i framtiden. Med rätt förutsättningar skulle möjligheterna att få elever i grundskolan att avsluta någon kurs i moderna språk utöver engelska i grundskolan kunna öka.

    360 Degree Mixed Reality Environment to Evaluate Interaction Design for Industrial Vehicles Including Head-Up and Head-Down Displays2018In: Lecture Notes in Computer Science , Volume 10910, 2018, p. 377-391Conference paper (Refereed)
    Abstract [en]

    Designing and testing new information and safety features for industrial vehicles do not need to involve the realization of high-fidelity and expensive simulators. We propose a low-cost mixed reality environment which allows for rapid development and rearrangement of a virtual and physical setup of a simulator for industrial vehicles. Our mixed reality simulator allows for safe testing of controls, information, and safety features to support drivers of industrial vehicles. In this paper, we test the implications of showing extra digital information to excavator drivers through a virtual environment, an external head-up display as well as a head-down display. Through user tests we have seen first indications that projected information through our mixed reality system and content on a head-up display is perceived as more helpful and intuitive than using head-down displays, when controlling our industrial vehicle simulator. Moreover, we have seen that the fear of overseeing an obstacle or other important information is lower when using a head-up display, in comparison to other tested visualization options. © Springer International Publishing AG, part of Springer Nature 2018.

    3-D Nautical Charts and Safe Navigation2006Doctoral thesis, monograph (Other scientific)
    Abstract [en]

    In spite of all electronic navigation devices on a modern ship bridge, navigators still lose their orientation. Reasons for this might be excessive cognitive workload caused by too many instruments to read and compile, navigation information that is displayed in a cognitively demanding way, short decision times due to high speed or fatigue due to minimum manning and long work hours.

    This work addresses the problem of map information displayed in a less than optimal way. Three new concepts are presented: the bridge perspective, the NoGO area polygons and a dual lane seaway network. Map reading can be difficult due to the problem of mental rotations. By allowing a 3-D nautical chart to be viewed from an egocentric bridge perspective, the need for mental rotations can be removed. The cognitively demanding calculations necessary to find out if there is enough water under the keel can be made by the chart system and the result displayed as of free water and NoGo areas. On land car driving is facilitated by a road-network and a sign system. This notion can be further developed on sea and make navigation easier and safer.

    These concepts were then tested in a laboratory experiment, in interviews and in a prototyping project. The results were very promising. The experiment in a laboratory maze showed that map reading from an egocentric perspective was more efficient than using traditional paper and electronic maps. Interviews and expert evaluation of prototypes also showed great interest from practitioners in the field.

    3-D Nautical Charts as Decision Support for Land Based Piloting2008In: Proceedings of the 1st International Ship-Port-Interface Conference (ISPIC 2008): The Human Element at the Ship/Port Interface, Kiel: Buchwrft-verlag.de , 2008, p. 191-198Conference paper (Refereed)
    Abstract [en]

    In the event that remote pilotage is introduced in a wider extent, this paper suggests using nautical charts displayed in a 3-D egocentric perspective to improve situation awareness for both for the land based pilot and the bridge crew of the pilotless ship. The system will allow the port to send pre-planned routes with times and courses to individual ships, and present them in an ergonomic and intuitive way. The efficiency of the 3-D egocentric view has been shown in previous research.

    3D Surround Sound Application for Game Environments2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report covers the creation and implementation of a 3D audio application using FMOD Ex API. The report will also cover a walkthrough of the basic principles of 3D and surround audio, examples of other uses of 3D audio, a comparison between available technologies today, both software and hardware and finally the result of the implementation of the 3D sound environment software, both server and client. The application was created to explore the use of 3D audio in immersive environments. There was no application like this available when this project was conducted. An inductive approach along with a form of rapid application development and scenario creation was used to achieve the results presented in this report. The implementation resulted in a working client and server software which is able to create a 3D sound environment. Based on a user evaluation the software proved to be quite successful. With the help of the implementation the user, or operator, can now create a sound environment for another user, or a listener. The environment is created and designed by the operator using the client side of the implementation and later played through the server side which is connected to a 4.1 speaker system. The operator can steer and add sounds from the client to an active environment and the listener can experience the change in real time. This project was conducted as a bachelor thesis in computer science at Mälardalens University in Västerås, Sweden.

    3D-sjökort och säker navigering2007Conference paper (Other (popular science, discussion, etc.))
    Abstract [en]

    Informationsdesignsforskaren Thomas Porathe presenterade i våras i en avhandling en ny metod att presentera sjökortsinformation på fartygsbryggan. Genom att visa kartan ur ett ”bryggperspektiv” uppnås en kognitiv avlastning som förenklar navigeringen, särskilt i höga hastigheter när informationstrycket är högt och beslutstiden kort.

    Problemet är att många människor har svårt att läsa kartor. Nästa alla har någon gång tvingats vända kartan ”upp och ner” i något gathörn för att bli klar över om det är till vänster eller höger färden skall gå. På sjön är den en dygd att hålla sjökortet orienterat i nord upp. Radarskärmar och elektroniska sjökort används också vanligen i denna orientering. När fartyget är på sydgående rör det sig alltså uppifrån och ner på sjökortet och en fyr som i verkligheten befinner sig till på styrbordssidan (till höger) om fartyget, återfinns till vänster på sjökortet. För att jämföra sjökortet med verkligheten tvingas navigatören till att mentalt rotera kartbilden 180 grader. Man har experimentellt kunnat visa att detta tar tid och det är svårt och kan bli fel. Vi människor har också olika lätt för mentala rotationer. Den så kallade ”spatiala förmågan” varierar och avtar dessutom med åldern. Ett sätt att förenklar navigeringen i själva ”körsituationen” är att presentera sjökortet ur ett bryggperspektiv där man ser samma vy på skärmen som genom vindrutan dagtid, men med sjökortsinformationen överlagrad på vattenytan.

    Ytterligare kognitiv avlastning kan uppnås genom att låta systemet räkna fram farbara och icke farbara vatten för rådande vattenstånd, det egna fartygets djupgående, sjöhävning och squat. Kanske också en fullt utbyggd infrastruktur av sjövägar med skilda körbanor och vägkorsningar virtuellt synliga i sjökortet som landsvägar på land kan göra det lättare att förutse mötande fartygs manövrer och underlätta beslutfattande i närsituationer.

    4. Att välja undervisningsinnehåll2014In: Lärande i handling / [ed] Britt Jakobson, Iann Lundegård & Per-Olof Wickman, Studentlitteratur, 2014, p. 47-58Chapter in book (Other academic)
    Abstract [sv]

    Ämnesinnehåll, arbetssätt och arbetsformer samverkar på ett övergripande sätt och bildar tillsammans det som i detta kapitel benämns undervisningssinnehåll. Jag inleder kapitlet med att argumentera för behovet att uppmärksamma att lärare arbetar inom undervisningstraditioner, vilka gör att de kommunicerar olika undervisningsinnehåll till eleverna. Därefter följer en kort redovisning om de mest utmärkande dragen hos traditionerna samt hur forskningen synliggjort dem. Till sist presenteras ett reflektionsverktyg för lärare/lärarlag som kan användas som stöd för att urskilja undervisningstraditioner i den egna verksamheten och därigenom på ett mer reflekterat sätt kunna förändra undervisningsinnehållet.

    500 gram kött och en flygbiljett, tack: En studie kring individens konsumtion av kött och flygresor2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Swedish government makes yearly monitoring of environmental goals and recent reports show that individuals have a great impact on the greenhouse effect due to their consumption of air travel and meat. On account of these climate changes this study intends to investigate and understand the consumer behavior of these individuals. Therefore qualitative interviews where used to map differences and similarities between individuals in different generations. The study shows that the main cause that affects the individual's consumer behavior is through the individual’s upbringing but also for other reasons. There are visible similarities and differences between different generations, which was an expected outcome. Furthermore they express a high degree of awareness about climate change and also a willingness to change their actions. Their willingness is however limited and they are not fully ready to leave their old consumer patterns. The reasons described are fear of limited freedom. Measures that aim to limit climate change are in some cases in conflict with individual’s traditions and their childhood memories.

    72 hours to innovation as creative democracy2008Conference paper (Refereed)
    Abstract [en]

    Opening up innovation processes requires the development of forceful and efficient practices and methods that is able to mobilize and pool the creative capacities of a broader range of people. This paper will focus on a collaborative innovation design – the Innovation Plant - that in its concentrated form is a 72 hours innovation race. The purpose of the paper is to conceptualize and interpret the “72 hours to innovation” methodology from the point of view of “creative democracy”, the mobilisation of the creative capacity of all. As a form of crowd sourcing, the methodology develops concentrated creativity in order to radically accelerate innovation.

    A 10-year follow-up of tailored behavioural treatment and exercise-based physiotherapy for persistent musculoskeletal pain2017In: Clinical Rehabilitation, ISSN 0269-2155, E-ISSN 1477-0873, Vol. 31, no 2, p. 186-196Article in journal (Refereed)
    Abstract [en]

    Objective: To study the long-term outcomes of two interventions targeting patients with sub-acute and persistent pain in a primary care physiotherapy setting. Design: A 10-year follow-up of a two-armed randomised controlled trial, initially including 97 participants. Interventions: Tailored behavioural medicine treatment, applied in a physiotherapy context (experimental condition), and exercise-based physiotherapy (control condition). Main measures: Pain-related disability was the primary outcome. The maximum pain intensity, pain control, fear of movement, sickness-related absence (register data) and perceived benefit and confidence in coping with future pain problems were the secondary outcomes. Results: Forty-three (44%) participants responded to the follow-up survey, 20 in the tailored behavioural medicine treatment group and 23 in the exercise-based physiotherapy group. The groups did not differ in terms of the change in the scores for the primary outcome (p=0.17) of pain-related disability between the experimental group (median: 2.5, Q1-Q3: -2.5-14.25), and the control group (median: 0, Q1-Q3: -5-6). Further, there were also no significant differences found for the secondary outcomes except for sickness-related absence, where the exercise-based physiotherapy group had more days of sickness-related absence three months before treatment (p= 0.02), and at the 10-year follow-up (p=0.03). Discussion: The beneficial effects favouring tailored behavioural medicine treatment that observed post-treatment and at the two-year follow-up were not maintained 10 years after treatment.

    A 2-layer component-based architecture for heterogeneous CPU-GPU embedded systems2016In: Advances in Intelligent Systems and Computing, Volume 448, 2016, p. 629-639Conference paper (Refereed)
    Abstract [en]

    Traditional embedded systems are evolving into heterogeneous systems in order to address new and more demanding software requirements. Modern embedded systems are constructed by combining different computation units, such as traditional CPUs with Graphics Processing Units (GPUs). Adding GPUs to conventional CPU-based embedded systems enhances the computation power but also increases the complexity in developing software applications. A method that can help to tackle and address the software complexity issue of heterogeneous systems is component-based development. The allocation of the software application onto the appropriate computation node is greatly influenced by the system information load. The allocation process is increased in difficulty when we use, instead of common CPU-based systems, complex CPU-GPU systems. This paper presents a 2-layer component-based architecture for heterogeneous embedded systems, which has the purpose to ease the software-to-hardware allocation process. The solution abstracts the CPU-GPU detailed component-based design into single software components in order to decrease the amount of information delivered to the allocator. The last part of the paper describes the activities of the allocation process while using our proposed solution, when applied on a real system demonstrator.

    Abstract [en]

    A 3-D Nautical GIS is suggested in this paper. The system is aimed at nautical navigation and simplifies navigation by adding three major features to existing chart systems: The egocentric view, by allowing the geographical data to be viewed from an bridge perspective the problem of mental rotations is removed; the seaways, displaying traffic separated fairways and individual track lines and the NoGo area polygons displaying warning areas for waters too shallow for the individual ship in the current tidal situation.

    A 5-to 8-year randomized study on the treatment of cervical radiculopathy: anterior cervical decompression and fusion plus physiotherapy versus physiotherapy alone2017In: JOURNAL OF NEUROSURGERY-SPINE, ISSN 1547-5654, Vol. 26, no 1, p. 19-27Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE The aim of this study was to evaluate the 5- to 8-year outcome of anterior cervical decompression and fusion (ACDF) combined with a structured physiotherapy program as compared with that following the same physiotherapy program alone in patients with cervical radiculopathy. No previous prospective randomized studies with a follow-up of more than 2 years have compared outcomes of surgical versus nonsurgical intervention for cervical radiculopathy. METHODS Fifty-nine patients were randomized to ACDF surgery with postoperative physiotherapy (30 patients) or to structured physiotherapy alone (29 patients). The physiotherapy program included general and specific exercises as well as pain coping strategies. Outcome measures included neck disability (Neck Disability Index [NDI]), neck and arm pain intensity (visual analog scale [VAS]), health state (EQ-5D questionnaire), and a patient global assessment. Patients were followed up for 5-8 years. RESULTS After 5-8 years, the NDI was reduced by a mean score% of 21 (95% CI 14-28) in the surgical group and 11% (95% CI 4%-18%) in the nonsurgical group (p = 0.03). Neck pain was reduced by a mean score of 39 mm (95% CI 26-53 mm) compared with 19 mm (95% CI 7-30 mm; p = 0.01), and arm pain was reduced by a mean score of 33 mm (95% CI 18-49 mm) compared with 19 mm (95% CI 7-32 mm; p = 0.1), respectively. The EQ-5D had a mean respective increase of 0.29 (95% CI 0.13-0.45) compared with 0.14 (95% CI 0.01-0.27; p = 0.12). Ninety-three percent of patients in the surgical group rated their symptoms as "better" or "much better" compared with 62% in the nonsurgical group (p = 0.005). Both treatment groups experienced significant improvement over baseline for all outcome measures. CONCLUSIONS In this prospective randomized study of 5- to 8-year outcomes of surgical versus nonsurgical treatment in patients with cervical radiculopathy, ACDF combined with physiotherapy reduced neck disability and neck pain more effectively than physiotherapy alone. Self-rating by patients as regards treatment outcome was also superior in the surgery group. No significant differences were seen between the 2 patient groups as regards arm pain and health outcome.

    A 7 year long measurement period investigating the correlation of corrosion, deposit and fuel in a biomass fired circulated fluidized bed boiler2011In: Applied Energy, ISSN 0306-2619, E-ISSN 1872-9118, Vol. 88, no 1, p. 99-110Article in journal (Refereed)
    Abstract [en]

    The present investigation involves a unique, 7 year (2001-2007) long study of corrosion and deposits on superheater tubes in a biomass fired circulated fluidized bed boiler. These measurements are correlated against the different fuels used over this period. In the earlier years, the boiler was run with a mixture of different biomass fuels and peat. In later years, recycled wood was introduced into the fuel mix. The deposit growth rate approximately doubled when the recycled wood content of the fuel was increased to 10-20%. Small amounts of chlorine and zinc were found both in the recycled wood and in the deposit layer. These elements together with alkali metals from the biomass, have the potential to form sticky compounds that increase the deposit growth rate. The corrosion rate of the superheater tubes varied over the study period. A number of possible explanations for this phenomenon are discussed.

    A* Algorithm for Graphics Processors2010In: THIRD SWEDISH WORKSHOP ON MULTI-CORE COMPUTING - MCC'10, Chalmers University of Technology, Sweden, 2010Conference paper (Refereed)
    Abstract [en]

    Today's computer games have thousands of agents moving at the same time in areas inhabited by a large number of obstacles. In such an environment it is important to be able to calculate multiple shortest paths concurrently in an efficient manner. The highly parallel nature of the graphics processor suits this scenario perfectly. We have implemented a graphics processor based version of the A* path finding algorithm together with three algorithmic improvements that allow it to work faster and on bigger maps. The first makes use of pre-calculated paths for commonly used paths. The second use multiple threads that work concurrently on the same path. The third improvement makes use of a scheme that hierarchically breaks down large search spaces. In the latter the algorithm first calculates the path on a high level abstraction of the map, lowering the amount of nodes that needs to be visited. This algorithmic technique makes it possible to calculate more paths concurrently on large map settings compared to what was possible using the standard A* algorithm. Experimental results comparing the efficiency of the algorithmic techniques on a NVIDIA GeForce GTX 260 with 24 multi-processors are also presented in the paper.

    A Balance of Social Inclusion and Risks: Staff Perceptions of Information and Communication technology in the Daily Life of Young Adults with Mild to Moderate Intellectual Disability in a Social Care ContextIn: Journal of Policy and Practice in Intellectual Disabilities, ISSN 1741-1122, E-ISSN 1741-1130Article in journal (Refereed)
    Abstract [en]

    Background: Information and communication technology (ICT) has increased in importance and facilitates participation in several life areas throughout society. However, young adults with mild to moderate intellectual disability make less use ICT than the general population. Disability services staff play a central role in supporting and enabling service users in daily life, and their perceptions of ICT are important to their role in service provision.

    Aim: To describe staff perceptions of the role of ICT and how it affects daily life in young adults with mild to moderate intellectual disability living in residential homes.

    Method: Focus group interviews and individual interviews were conducted with staff working in residential homes in which young adults with mild to moderate intellectual disability live. All materials were transcribed verbatim and analysed using latent content analysis.

    Findings: Staff perceived ICT and, more specifically, the Internet as being supportive of both daily life and social relationships of these young adults, but they also viewed ICT as posing social risks. Perceptions of and support for ICT were related to staff perceptions about what is appropriate and manageable in relation to an individual resident’s functioning level. Staff members also considered the views of parents about appropriate content when providing support.

    Discussion: Staff in residential homes for young adults with mild to moderate intellectual disability use their implicit moral judgement about the use of ICT by residents. Their enablement of and support for ICT are not primarily based on the service user’s wishes or interests. This finding implies a risk that the organization of a conflict-free service provision is a higher priority than service users’ participation in social life.

    A balance of strategic management and entrepreneurship practices—The renewal journey of the Swedish Public Employment Service2018In: Financial Accountability and Management, ISSN 0267-4424, E-ISSN 1468-0408, Vol. 34, no 4, p. 354-366Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is to study the first phase—from 2014 to 2016—of the Swedish Public Employment Service's renewal journey by examining how the agency worked to achieve its new strategy through processes of strategic management and entrepreneurship. We did this through the theoretical lens of strategic entrepreneurship (SE). The results showed that the agency's renewal processes are simultaneously entrepreneurial and strategic. The agency is historically well known for its detailed management and control, which creates several tensions with entrepreneurship. We contributed to previous literature by focusing on the organizational aspects of these tensions and the SE practices of balancing entrepreneurship with strategic management.

    A behavioral medicine intervention for community-dwelling older adults with chronic musculoskeletal pain: Protocol for a randomized controlled trial2017In: Journal of Pain Research, ISSN 1178-7090, E-ISSN 1178-7090, Vol. 10, p. 845-853Article in journal (Refereed)
    Abstract [en]

    Background: Chronic musculoskeletal pain is a major health problem among older adults, particularly those who live alone and/or those who are dependent on formal care. Chronic pain is associated with mobility problems, falls, fear of falling, catastrophizing thoughts, and a lower quality of life. Research shows that physical therapy interventions based on behavioral medicine approaches are beneficial for middle-aged adults with chronic pain. However, there appears to be no previous randomized controlled trials (RCTs) based on this theoretical framework that have examined the effect on older adults with chronic musculoskeletal pain who live alone at home and are dependent on formal care to manage their everyday lives. The aim of the planned study is to evaluate the effect of an individually tailored integrated physical therapy intervention based on a behavioral medicine approach compared with the effect of standard care. Methods/design: The planned study is an RCT that will include one intervention and one control group involving a total of 150 adults aged ≥75 years with chronic musculoskeletal pain who live alone at home and are dependent on formal care to manage their everyday lives. The intervention will involve a 12-week home-based individually tailored intervention that will be designed to enhance the participants’ ability to perform everyday activities by improving physical function and reducing pain-related disability and beliefs. The control group will be given standard care, including general advice about physical activity. The participants will be assessed at baseline and at 3 and 6 months after baseline. The primary outcome will be pain-related disability and physical performance. Discussion: The intervention, if effective, will have the potential to be the basis of the first evidence-based guidelines for physical therapists who work with older adults with chronic musculoskeletal pain.

    A behavioral medicine intervention for older women living alone with chronic pain - a feasibility study2014In: Clinical Interventions in Aging, ISSN 1176-9092, E-ISSN 1178-1998, Vol. 9, p. 1383-1397Article in journal (Refereed)
    Abstract [en]

    Background: To be an older woman, live alone, have chronic pain, and be dependent on support are all factors that may have an impact on daily life. One way to promote ability in everyday activities in people with pain-related conditions is to use individualized, integrated behavioral medicine in physical therapy interventions. How this kind of intervention works for older women living alone at home, with chronic pain, and dependent on formal care to manage their everyday lives has not been studied. The aim was to explore the feasibility of a study and to evaluate an individually tailored integrated behavioral medicine in physical therapy intervention for the target group of women. Materials and methods: The study was a 12-week randomized trial with two-group design. Primary effect outcomes were pain-related disability and morale. Secondary effect outcomes focused on pain-related beliefs, self-efficacy for exercise, concerns of falling, physical activity, and physical performance. Results: In total, 23 women agreed to participate in the study and 16 women completed the intervention. The results showed that the behavioral medicine in physical therapy intervention was feasible. No effects were seen on the primary effect outcomes. The experimental intervention seemed to improve the level of physical activity and self-efficacy for exercise. Some of the participants in both groups perceived that they could manage their everyday life in a better way after participation in the study. Conclusion: Results from this study are encouraging, but the study procedure and interventions have to be refined and tested in a larger feasibility study to be able to evaluate the effects of these kinds of interventions on pain-related disability, pain-related beliefs, self-efficacy in everyday activities, and morale in the target group. Further research is also needed to refine and evaluate effects from individualized reminder routines, support to collect self-report data, safety procedures for balance training, and training of personnel to enhance self-efficacy.

    A Below-Average Effect with Respect to American Political Stereotypes on Warmth and Competence2015In: Political Psychology, ISSN 0162-895X, E-ISSN 1467-9221, Vol. 36, no 3, p. 341-350Article in journal (Refereed)
    Abstract [en]

    The "above-average effect" is the phenomenon that people tend to judge themselves above average on desirable traits. Based on social identity theory, we propose that a "below-average effect" may arise when individuals rate themselves and the average ingroup member on traits stereotypically associated with the ingroup. In two studies, Republican and Democrat participants rated themselves and the average political ingroup member on possession of desirable traits related to warmth and competence. Current political stereotypes in America associate the former dimension with Democrats and the latter with Republicans. Consistent with our hypothesis, the above-average effect was moderated by political group and dimension in interaction. In particular, Democrats rated themselves below the average Democrat on warmth and Republicans rated themselves below the average Republican on competence.

    A biophysically anchored production function2010In: Environment, Development and Sustainability, ISSN 1387-585X, E-ISSN 1573-2975, Vol. 12, no 4, p. 573-596Article in journal (Refereed)
    Abstract [en]

    The first part presents a conceptual model of the economic system in its ecological and social context. It is developed via an integration of basic concepts in physical resource theory, animal and human physiology, economic theory and systems ecology. The capacity of the model to support analysis of such complex systems where life is a key system characteristic is high. The conceptual model shows the dependency of the human economy on support by non-renewable and renewable resources from Nature (i. e. ecological source restrictions), as well as the capacity of ecosystems to assimilate wastes (ecological sink restrictions). The analysis focuses general principles; thus, the high level of abstraction results in an apparent simplicity. In the second part, we integrate traditional economic production functions and the conceptual model, which results in the formulation of a biophysically anchored production function (BAPF). The BAPF by itself, and through the system of ecological economic accounts that can be derived from it, represent a toolbox that supports the operationalisation of a sustainable development from micro to macro level. It is coherent with Impredicative Loop Analysis, existing management systems within agricultural sciences, OECD's principles for sustainable development and the approach of Millennium Ecosystem Assessment. Compared to analytical approaches used in the formulation of sustainability policies in the private and public sphere, based on conceptual models ignoring the complexity when life (bios) is a defining system characteristic, its relevance for the operationalisation of sustainable development approaches infinity. The third part presents results from statistical analysis of relations between gross domestic product and energy supply and some emissions, respectively, for different nations and time periods, delivering values on levels and trends for parameters in the BAPF as well as a first test of the relevance of the BAPF proposed. The paper is ended by a theoretical analysis of the costs of provoking an economic system working under ecological source and sink restrictions to follow exponential growth: The need to decouple economic growth from natural resource use and emissions is highlighted. Otherwise, the erosion of the ecological foundation of the economy with regard to source as well as sink aspects will be a function of exponential growth

    A Black-Box Approach to Latency and Throughput Analysis2017In: Proceedings - 2017 IEEE International Conference on Software Quality, Reliability and Security Companion, QRS-C 2017, 2017, p. 603-604, article id 8004393Conference paper (Refereed)
    Abstract [en]

    To enable fast and reliable delivery of mobile text messages (SMS), special bidirectional protocols are often used. Measuring the achieved throughput and involved latency is however non-trivial, due to the complexity of these protocols. Modifying an existing system would incur too much of a risk, so instead a new tool was created to analyse the log files containing information about this traffic in a black-box fashion. When the produced raw data was converted into graphs, they gave new insights into the behaviour of both the protocols and the remote systems involved.

    A Bluetooth Radio Energy Consumption Model for Low Duty-Cycle Applications2012In: IEEE Transactions on Instrumentation and Measurement, ISSN 0018-9456, E-ISSN 1557-9662, Vol. 61, no 3, p. 609-617Article in journal (Refereed)
    Abstract [en]

    This paper presents a realistic model of the radio energy consumption for Bluetooth-equipped sensor nodes used in a low-duty-cycle network. The model is based on empirical energy consumption measurements of Bluetooth modules. This model will give users the possibility to optimize their radio communication with respect to energy consumption while sustaining the data rate. This paper shows that transmission power cannot always be directly related to energy consumption. Measurements indicate that, when the transmission power ranges from $-$5 to $+$10 dBm, the difference in consumed energy can be detected for each transmission peak in the sniff peak. However, the change is negligible for the overall energy consumption. The nonlinear behavior of the idle state for both master and slave when increasing the interval and number of attempts is presented. The energy consumption for a master node is in direct relation to the number of slaves and will increase by approximately 50% of the consumption of one slave per additional slave, regardless of the radio setting.

    “A body in transformation”: - An Empirical phenomenological study about fear-avoidance beliefs towards physical activity among persons experiencing moderate to severe rheumatic pain2018In: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, p. 1-9Article in journal (Refereed)
    Abstract [en]

    Aims. To gain a better understanding of fear-avoidance beliefs towards physical activity and body awareness in people experiencing moderate to severe rheumatic pain.  Background. Rheumatoid arthritis and psoriatic arthritis are long-term conditions with pain as the prominent symptom. Health-promoting physical activity is recommended, and can have an analgesic effect. High self-rated pain has previously been reported to be associated with increased fear-avoidance behaviour in relation to physical activity. Body awareness, which includes attentional focus and awareness of internal body sensations, could be valuable in the nursing care of long-term diseases.   Design. Empirical phenomenological.  Methods. An empirical phenomenological psychological method was applied. Interviews were undertaken in 2016 with 11 informants (eight females and three males, age range 44–71 years) who were diagnosed with rheumatoid arthritis (n = 7) or psoriatic arthritis (n = 4), with a disease duration ranging from 3–35 years. The mean visual analogue scale score in the study sample was 60 mm.   Results. Three typologies were identified: “My relatively fragile physical status”, “I am an active creator” and “Part of something bigger than myself.” Conclusions. The current findings indicated that pain anticipation and fear-avoidance beliefs towards physical activity sometimes affected the behaviour of individuals with long-term rheumatic pain syndromes. People experiencing moderate to high rheumatic pain tended to focus on their fragile physical and emotional state. By adopting a more favourable attitude towards the self, the body could be restored to a state of calm and balance.  Relevance to clinical practice. The current findings are relevant for healthcare professionals engaged in health-promotion clinical practice.

    A BRAIN-ACTUATED ROBOT CONTROLLER FOR INTUITIVE AND RELIABLE MANOEUVRING2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    During this master-thesis a robot controller designed for low-throughput and noisy EEG-data of a Brain Computer Interface (BCI) is implemented. The hypothesis of this master-thesis state that it is possible to design a modular and platform independent BCI-based controller for a mobile robot, which regulates the autonomy of the robot as a function of the user’s will to control. The BCI design is thoroughly described, including both the design choices regarding used brain activity signals and the pre- and post-processing of EEG data. The robot controller is experimentally tested by completing a set of missions in a simulated environment. Both quantitative and qualitative data is derived from the experimental test setup and used to evaluate the controller performance with different levels of induced noise. Additional to the robot control performance result, an offline validation of the BCI performance is depicted. Strength and weaknesses of the system design is presented based on the acquired result, and suggested solutions to improve the over-all performance is given. The produced result show that using the developed controller is a feasible approach for reliable and intuitive manoeuvring of a telepresence robot.
