    Through an imperialistic gaze?: Journalism, ideology and the notion of democracy2015In: Differences, Inequalities and Sociological Imagination: Abstract Book, Prague: Institute of Sociology of the Czech Academy of Sciences , 2015, p. 929-930Conference paper (Other academic)
    Abstract [en]

    Despite that the notion of democracy has a central place in the Western self-image, and also in media studies, research that focuses on how democracy is ideologically loaded in journalistic content is still in its infancy. In recent times, democracy has been used with great enthusiasm by Western political leaders, while the meaning of democracy perhaps is more fuzzy than ever. In times of economic and political crisis, and of a weak Left in most European countries, it is important to examine how journalism constructs notions of democracy, and how such notions reflect specific political positions and interests. This study, which is theoretically rooted in ideology critique, and methodologically inspired by critical discourse analysis, examines how news journalism in the coverage of Venezuela and the Ukraine conflict constructs notions of democracy. The study is specially interested in exploring and discussing the ideological interconnections between imperialism and geopolitical interests, and the journalistic construction of democracy.

    Through Eurocentric logics: The construction of difference in foreign news discourse on Venezuela2016In: Journal of Language and Politics, ISSN 1569-2159, E-ISSN 1569-9862, Vol. 15, no 1, p. 94-115Article in journal (Refereed)
    Abstract [en]

    This study aims to explore the construction of difference in foreign news discourse on culturally similar but politically different non-Western subjects. Applying critical discourse analysis (CDA) together with a critique of Eurocentrism, the study examines difference in newspaper constructions of government supporters and oppositional groups in Venezuela. Discursive differences are evident in the strategies used for constructing the two groups with regard to political rationality and violence. Government supporters are associated with social justice, Venezuela’s poor, dogmatic behavior, and the use of political violence. The opposition, in contrast, is constructed as following a Western democratic rationale that stresses anti-authoritarianism. This group is primarily associated with victims of violence. While the opposition is conveyed as being compatible with Eurocentric values and practices, government supporters to great extent deviate from these norms. Such constructions serve to legitimize politico-ideological undercurrents of Eurocentrism, as the defense of liberalism.

    Weeds in the Hegemony: Understanding Journalism on the Renegotiation of Cannabis2018Conference paper (Refereed)
    Abstract [en]

    We are witnessing the renegotiation of cannabis substances in many parts of the world. After being classified as narcotics and subjected to a worldwide ban for several decades, cannabis has now been legalized in Uruguay and in several US states, and decriminalized in some other countries. This paper aims to study how the ongoing renegotiation of cannabis, which involves the legalization of the substance in different parts of the world, is constructed in Swedish print news journalism. This is done with the purpose of understanding how news journalism in a context of a traditionally strong drug prohibition (de)legitimizes different positions and perspectives in the ongoing renegotiation of cannabis, and to what extent journalism in such a context offers challenges to the reigning prohibitionist hegemony. Although cannabis and the media has been researched extensively, very few studies have been conducted by media and communication or journalism scholars, and contributions have been placed mainly in areas as for example drug policy, drug use and misuse, and public health. The current study, in contrast, wishes to contribute to the critical study of drug journalism. The paper draws on critical theory, understanding the ongoing renegotiation of cannabis as bringing disequilibrium to the hegemonic view of cannabis as dangerous drug that needs to be banned. Journalism is perceived as playing a key role in this context, since journalism is an arena where different discourses on cannabis struggle for prominence. Journalism can in this sense serve the strengthening of counter-hegemonic discourses on cannabis or the reinforcement of the prohibitionist hegemony. The study uses critical discourse analysis as a method to study 49 print newspaper items. The results show that the studied media invites opposed discourses regarding the health risks and the medical benefits of cannabis to be part of the news pages, which creates a somewhat pluralistic view on cannabis. The study also finds that the construction of cannabis legalization as a means to combat organized crime is given significant framing power. These results suggest that the ongoing renegotiation of cannabis in different parts of the world invites Swedish journalism to broaden the debate on the substance and to provide certain legitimacy to positive discourses on cannabis that are otherwise considered deviant in the Swedish drug debate. This serves as an example of how changes in distant political contexts affect the ways in which journalism ascribes legitimacy to specific discourses on drugs.

    Digitalisering och social exklusion: Om medborgares användning av och attityder till Arbetsförmedlingens digitala tjänster2008Book (Other academic)
    Abstract [en]

    This research report focuses on the users of e-government in a social science perspective. Our aim is to study how different social groups, registered at the Swedish Public Employment Service, relate to the internet, the agency and the services offered on its website (www.ams.se).

    The field of e-government research is dominated by studies that centre attention on the supply side (videlicet research investigating the entrance of IT in organizations and the implications that new technology have to these), while usercentred research (demand side) is still scarce. Our study, focusing on how citizens relate to the internet in general and e-government in particular, therefore helps to bridge a knowledge gap within the field.

    Our survey is based on a questionnaire sent to 2 000 randomly selected persons, all registered at the Swedish Public Employment Service. Of these, 762 job seekers responded, which gives us a frequency rate of 40 percent. The questions asked were related to the job seekers’ usage of and attitudes towards the internet in general and the agency’s webpage in particular, but also to their attitudes to the Swedish Public Employment Service.

    The main results show that social factors, particularly education, play a major role for the job seekers’ ability to use the web based services offered by the agency. People with a lower educational level are less inclined to use the agency’s website, and at the same time they experience the site as more complicated to use. We also found a strong link between the relations to the internet (access, usage, experience and attitudes) and the relations to the agency’s website. Those with advantaged internet relations – mostly well educated people, white collars and people living in bigger cities – also use the agency’s website more diligently and tend to have more positive attitudes towards it (and vice versa). Thus, its necessary to talk in terms of digitally well equipped and less well equipped groups.

    The unequal relations to the internet in general and the agency’s website in particular not only indicate that e-government is more suitable for the digitally well equipped, but that it in fact exclude those with less digital resources. This new kind of exclusion has great implications for the job seekers’ possibilities to enter the labour market, and to act their role as citizens. If e government also means a reformation of the citizen role – in the sense of increased individual responsibility towards the government - not bridging the digital divide will carry even more exclusion to those that’s already excluded.

    Abstract [sv]

    I föreliggande rapport studeras vilka sociala värden som elitidrotten och kulturen genererar för invånarna i landsortspräglade län som Blekinge, Halland, Kalmar och Kronoberg. Studien syftar till att lämna ett bidrag till den samhällsvetenskapliga idrottsforskningen, och ge ökad kunskap om idrottens och kulturens betydelse för den regionala utvecklingen.

    Studiens material vilar på en postenkät skickad till 1500 slumpmässigt utvalda personer i respektive län. Det sammanlagda antalet besvarade enkäter uppgick till 3181 stycken, vilket ger en nettosvarsfrekvens på 54 procent.

    Rapporten visar bland annat att både idrott och kultur värderas relativt högt och konsumeras i relativt stor utsträckning. Beträffande idrott konsumeras främst breddidrottsliga evenemang, och vad gäller kultur besöks bibliotek och biografer oftare än exempelvis teatrar.

    Studien visar också att de kultur- respektive idrottsintresserade skiljer sig åt vad gäller demografi, men även vad gäller livsstil. De idrottsintresserade har en mer folklig och lantlig prägel, medan de kulturintresserade är att betrakta som en välutbildad kosmopolitisk grupp. Med tanke på de sistnämndas ökade rörlighet är satsningar på kultur ej att förringa. Denna typ av satsningar kan få denna resursstarka grupp att dels stanna kvar i landsorten, dels flytta in till densamma.

    Abstract [en]

    In the area of governmental information for and services to citizens digitalization has certainly become a buzzword. Framed within the discourses on e-government or e-governance – or differ­ent mixtures of the two – various analyses have tried to point out, or even anticipate possible consequences of the appropriation of digital technologies, mainly the internet, in governmental services.

    On the one hand, these analyses have pointed out a great deal of opportunities connected to the incorporation of the internet into governmental information and services. Policy makers have been quick to point to the increased accessibility as a great opportunity for the citizens; in Sweden this vision of accessibility has even been referred to as ‘24:7-governmental agencies’. Academics, among others, have also suggested that the digitalization of information and services opens up new possibilities for citizen control of governments.

    On the other hand, a number of problems have also been identified. For instance, the digitalization of public registers holding personal information has been interpreted as a threat to the citizens’ integrity: Will digitalization bring a new surveillance society? The most frequently debated prob­lem, however, at least within research, has been the fear of digital divides. Will the internet create digital cleavages between different groups of citizens?

    So far, however, neither the hopeful nor the dystopian analyses have made enough efforts to critically evaluate their claims. Such evaluations can start from different points of departure, and in this paper the starting point is the citizens as users of governmental information and services through the internet: What patterns of inclusion and exclusion emerge as a governmental agency digitalizes its information and services by making them increasingly internet based?

    The paper presents statistical data from a survey of 762 unemployed citizens using the Swedish Public Employment Service, a governmental agency that has come to rely specifically heavy on internet based information and service. The initial analysis of data reveals interesting differences between social groups in terms of both perception and use of the internet – in general – and the resources offered by SPES in particular. For instance, the users’ various degrees of education is a strong, determining factor when it comes to use of internet SPES’ services.

    The paper starts from a conceptual elaboration of various notions of e-government and e-gov­ernance. Thereafter, the survey data is described and elaborated on before moving into a discus­sion of the wider significance of the findings: What does data suggest in terms of patterns of in­clusion in and exclusion from a society in which governmental agencies, to an increasing extent, use the internet for their information and services?

    Results for PCDD/PCDF and dl-PCBs in the first round of UNEPs biennial global interlaboratory assessment on persistent organic pollutants2013In: TrAC. Trends in analytical chemistry, ISSN 0165-9936, E-ISSN 1879-3142, Vol. 46, p. 98-109Article in journal (Refereed)
    Abstract [en]

    The first worldwide interlaboratory assesment on persistent organic pollutants (POPs) under the Stockholm Convention was organized in the Asian/Pacific, Latin American and African regions during 2009-11.

    A relatively large number of laboratories reported data for the PCDDs/PCDFs and dioxin-like PCBs, especially in the Asian region. Within the Asian region, several participants used high-resolution GC/high-resolution MS systems optimized for dioxin analysis. The availibility of High-resolution mass spectrometer instrumentation is limited in the Latin America and African regions, although recently several new laboratories for dioxins have started in the Latin American region.

    Analysis of transports with pharmaceuticals on Arlanda airport2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Rapporten syftar till att kartlägga och analysera dagens transportflöde av läkemedel på fraktområdet Cargo City på Arlanda. Cargo Center och APH Logistics är två fraktagenter som har sin verksamhet på Cargo City. Observera att Cargo City och Cargo Center inte har samma innebörd. Cargo Center och APH Logistics erbjuder genom nära samarbete transport och hantering av temperaturkänsligt gods, som till exempel läkemedel. Läkemedel är värdefullt gods som kräver särskild skötsel vid transport, hantering och förvaring. Det ställer stränga krav på samtliga aktörer i försörjningskedjan. Genom studiebesök och intervjuer har författarna kartlagt det befintliga flödet av läkemedel. SACT, ett åkeri och dotterbolag till Cargo Center, utför transporten av godset till Cargo City med nerkylda lastbilar. APH Logistics omlastningsterminal på Cargo City är temperaturkontrollerad, vilket innebär att läkemedelsgodset förvaras och lastats i flygcontainrar där. Det färdiglastade godset forslas sedan vidare till Cargo Centers terminal. Där sker vikt- och volymkontroll av godset, det registreras i olika datasystem och slutligen märks det med etiketter, så som flygfraktsedeln. Mycket av godset som hanteras på Arlanda körs med lastbil till andra flygplatser och destinationer runt om i Europa istället för att flygfraktas direkt från flygplatsen. Dessutom hanteras och förvaras inte allt läkemedelsgods under temperaturkontrollerade former. En totalkostnadsanalys har gjorts för att jämföra olika transportflödesscenarion. Dessutom har författarna identifierat den kundservice Cargo Center och APH Logistics bör erbjuda kunden. Den bygger på kvalitativa resonemang. Resultatet av rapporten är författarnas rekommendation till företagen av hur de bör gå tillväga i framtiden. Den ger både kortsiktiga och långsiktiga tips.

    Principalansvaret för vårdnadshavare: Föräldrars skadeståndsansvar för skada vållad av barn2016Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [sv]

    Personer under 15 år kan inte straffrättsligt bli ansvariga för brott de begått i enlighet med 1 kap 6§ BrB. Däremot kan en civilrättslig process gällande skadeståndsrättsligt anspråk bli aktuell i princip oberoende av skadevållarens ålder. Huvudregeln är alltså att barn kan bli skadeståndsskyldiga på samma sätt som en vuxen om de anses ha vållat skada. De större utmärkande skillnaderna mellan att hålla ett barn jämfört med en vuxen skadeståndsskyldig är att det görs en så kallad skälighetsbedömning när det gäller barn och även vid bedömning av barns culpa tar man mindre hänsyn till de subjektiva kriterierna. I denna uppsats utreds vårdnadshavarens ansvar enligt 3 kap. 5§ skadeståndslagen som infördes år 2010. Denna reglering innebär att föräldrar kan blir skadeståndsansvariga för skador som deras barn orsakar genom brott samt genom tillsynsansvaret som regleras i 6 kap. 2§ föräldrabalken. Denna paragraf reglerar att vårdnadshavaren skall ge barnet den tillsyn och uppsikt det behöver medhänsyn till ålder, utveckling och övriga omständigheter för att hindra skadevållande handlingar. Skillnaden mellan dessa respektive lagregler gällande att vårdnadshavaren skall anses vara skadeståndsansvarig är att den förra förutsätter att barnet begått ett brott och förutsätter heller ej culpa medan den senare inte gör det.

    ADHD: En kvalitativ studie om vuxna med ADHD2011Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    ADHD är den snabbast växande diagnosen på senare tid och har länge setts som en problematik främst förekommande bland barn. Den befintliga forskningen gällande ADHD är därför mer anpassad till yngre individer och syftet med denna studie är därför att undersöka vuxnas upplevelse och hur de förhåller sig till diagnosen samt omgivningens reaktioner gentemot ADHD utifrån respondentens perspektiv. För att kunna ta reda på detta intervjuades fem individer med ADHD och en kvalitativ forskningsansats valdes som metod för intervjuerna. Vidare valdes meningskoncentrering som analysmetod för intervjuerna då den kortar ner och koncentrerar utvalda citat som användes i analysen. För att tolka och analysera respondenternas upplevelser kring ADHD användes valda teorier som verktyg; stigma, rollteori samt jagpsykologi. Detta för att få en bredare förståelse för respondenternas upplevelser samt förklaringar utifrån teorierna. Slutsatsen berörde diskussioner gällande hur intervjurespondenterna lever med ADHD idag, hela utvecklingsprocessen som diagnosen gav upphov till samt omgivningens syn på ADHD som något avvikande. Utvecklingsprocessen som respondenterna genomlevde innan de accepterade diagnosen som en del av sin identitet gav upphov till en modell som tydligare förklarar de faser respondenterna upplevde. Detta från att diagnosen sattes tills de anammat diagnosen och även använde sig av den i positiva ändamål, exempelvis att arbeta med andra som har ADHD.

    Spectral Conditions for Stability and Stabilization of Positive Equilibria for a Class of Nonlinear Cooperative Systems2018In: IEEE Transactions on Automatic Control, ISSN 0018-9286, E-ISSN 1558-2523, Vol. 63, no 2, p. 402-417Article in journal (Refereed)
    Abstract [en]

    Nonlinear cooperative systems associated to vector fields that are concave or subhomogeneous describe well interconnected dynamics that are of key interest for communication, biological, economical, and neural network applications. For this class of positive systems, we provide conditions that guarantee existence, uniqueness and stability of strictly positive equilibria. These conditions can be formulated directly in terms of the spectral radius of the Jacobian of the system. If control inputs are available, then it is shown how to use state feedback to stabilize an equilibrium point in the interior of the positive orthant.

    Worldwide trends in body-mass index, underweight, overweight, and obesity from 1975 to 2016: a pooled analysis of 2416 population-based measurement studies in 128·9 million children, adolescents, and adults.2017In: The Lancet, ISSN 0140-6736, E-ISSN 1474-547X, Vol. 390, no 10113, p. 2627-2642Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults.

    METHODS: We pooled 2416 population-based studies with measurements of height and weight on 128·9 million participants aged 5 years and older, including 31·5 million aged 5-19 years. We used a Bayesian hierarchical model to estimate trends from 1975 to 2016 in 200 countries for mean BMI and for prevalence of BMI in the following categories for children and adolescents aged 5-19 years: more than 2 SD below the median of the WHO growth reference for children and adolescents (referred to as moderate and severe underweight hereafter), 2 SD to more than 1 SD below the median (mild underweight), 1 SD below the median to 1 SD above the median (healthy weight), more than 1 SD to 2 SD above the median (overweight but not obese), and more than 2 SD above the median (obesity).

    FINDINGS: Regional change in age-standardised mean BMI in girls from 1975 to 2016 ranged from virtually no change (-0·01 kg/m2 per decade; 95% credible interval -0·42 to 0·39, posterior probability [PP] of the observed decrease being a true decrease=0·5098) in eastern Europe to an increase of 1·00 kg/m2 per decade (0·69-1·35, PP>0·9999) in central Latin America and an increase of 0·95 kg/m2 per decade (0·64-1·25, PP>0·9999) in Polynesia and Micronesia. The range for boys was from a non-significant increase of 0·09 kg/m2 per decade (-0·33 to 0·49, PP=0·6926) in eastern Europe to an increase of 0·77 kg/m2 per decade (0·50-1·06, PP>0·9999) in Polynesia and Micronesia. Trends in mean BMI have recently flattened in northwestern Europe and the high-income English-speaking and Asia-Pacific regions for both sexes, southwestern Europe for boys, and central and Andean Latin America for girls. By contrast, the rise in BMI has accelerated in east and south Asia for both sexes, and southeast Asia for boys. Global age-standardised prevalence of obesity increased from 0·7% (0·4-1·2) in 1975 to 5·6% (4·8-6·5) in 2016 in girls, and from 0·9% (0·5-1·3) in 1975 to 7·8% (6·7-9·1) in 2016 in boys; the prevalence of moderate and severe underweight decreased from 9·2% (6·0-12·9) in 1975 to 8·4% (6·8-10·1) in 2016 in girls and from 14·8% (10·4-19·5) in 1975 to 12·4% (10·3-14·5) in 2016 in boys. Prevalence of moderate and severe underweight was highest in India, at 22·7% (16·7-29·6) among girls and 30·7% (23·5-38·0) among boys. Prevalence of obesity was more than 30% in girls in Nauru, the Cook Islands, and Palau; and boys in the Cook Islands, Nauru, Palau, Niue, and American Samoa in 2016. Prevalence of obesity was about 20% or more in several countries in Polynesia and Micronesia, the Middle East and north Africa, the Caribbean, and the USA. In 2016, 75 (44-117) million girls and 117 (70-178) million boys worldwide were moderately or severely underweight. In the same year, 50 (24-89) million girls and 74 (39-125) million boys worldwide were obese.

    INTERPRETATION: The rising trends in children's and adolescents' BMI have plateaued in many high-income countries, albeit at high levels, but have accelerated in parts of Asia, with trends no longer correlated with those of adults.

    Desafíos en la gestión de residuos sólidos para las ciudades de países en desarrollo [Solid waste management challenges for cities in developing countries]2015In: Tecnología en Marcha, ISSN 0379-3982, Vol. 28, no 2, p. 141-168Article in journal (Refereed)
    Abstract [en]

    Solid waste management is a challenge for the cities' authorities in developing countries mainly due to the increasing generation of waste, the burden posed on the municipal budget as a result of the high costs associated to its management, the lack of understanding over a diversity of factors that affect the different stages of waste management and linkages necessary to enable the entire handling system functioning. An analysis of literature on the work done and reported mainly in publications from 2005 to 2011, related to waste management in developing countries, showed that few articles give quantitative information. The analysis was conducted in two of the major scientific journals, Waste Management Journal and Waste Management and Research. The objective of this research was to determine the stakeholders' action/behavior that have a role in the waste management process and to analyze influential factors on the system, in more than thirty urban areas in 22 developing countries in 4 continents. A combination of methods was used in this study in order to assess the stakeholders and the factors influencing the performance of waste management in the cities. Data was collected from scientific literature, existing data bases, observations made during visits to urban areas, structured interviews with relevant professionals, exercises provided to participants in workshops and a questionnaire applied to stakeholders. Descriptive and inferential statistic methods were used to draw conclusions. The outcomes of the research are a comprehensive list of stakeholders that are relevant in the waste management systems and a set of factors that reveal the most important causes for the systems' failure. The information provided is very useful when planning, changing or implementing waste management systems in cities.

    Technology Reshaping Relationships:: The case of FöreningsSparbanken2001Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The financial system is currently undergoing structural changes all over the world. Thanks to the advances of technology, banks are also changing the way they interact with their customers. From a face-to-face to a faceless contact, via cash machines and the Internet, banks are urging to create effective communication channels that maintain close relationships with their customers. To better illustrate this situation, this study was based on the case of FöreningsSparbaken, a Swedish retail bank, which has a traditional structure and is also undergoing structural changes. With the implementation of new technologies, the bank's customers are experimenting some dissatisfaction concerning the new services provided. Little personal contact, reduction in service options and payment of Internet service fees are the major negative aspects that customers are facing with the bank's changes. These issues are addressed and discussed in this research on the basis of marketing approach.

    Annotating public fungal ITS sequences from the built environment according to the MIxS-Built Environment standard - a report from a May 23-24, 2016 workshop (Gothenburg, Sweden)2016In: MycoKeys, ISSN 1314-4057, E-ISSN 1314-4049, no 16, p. 1-15Article in journal (Refereed)
    Abstract [en]

    Recent molecular studies have identified substantial fungal diversity in indoor environments. Fungi and fungal particles have been linked to a range of potentially unwanted effects in the built environment, including asthma, decay of building materials, and food spoilage. The study of the built mycobiome is hampered by a number of constraints, one of which is the poor state of the metadata annotation of fungal DNA sequences from the built environment in public databases. In order to enable precise interrogation of such data - for example, "retrieve all fungal sequences recovered from bathrooms" - a workshop was organized at the University of Gothenburg (May 23-24, 2016) to annotate public fungal barcode (ITS) sequences according to the MIxS-Built Environment annotation standard (http:// gensc.org/ mixs/). The 36 participants assembled a total of 45,488 data points from the published literature, including the addition of 8,430 instances of countries of collection from a total of 83 countries, 5,801 instances of building types, and 3,876 instances of surface-air contaminants. The results were implemented in the UNITE database for molecular identification of fungi (http://unite.ut.ee) and were shared with other online resources. Data obtained from human/animal pathogenic fungi will furthermore be verified on culture based metadata for subsequent inclusion in the ISHAM-ITS database (http:// its. mycologylab.org).

    QoE-Aware Beamforming Design for Massive MIMO Heterogeneous Networks2018In: IEEE Transactions on Vehicular Technology, ISSN 0018-9545, E-ISSN 1939-9359, Vol. 67, no 9, p. 8315-8323Article in journal (Refereed)
    Abstract [en]

    One of the main goals of the future wireless networks is improving the users quality of experience (QoE). In this paper, we consider the problem of the QoE-based resource allocation in the downlink of a massive multiple-input multiple-output heterogeneous network. The network consists of a macrocell with a number of small cells embedded in it. The small cells base stations (BSs) are equipped with a few antennas, while the macro BS is equipped with a massive number of antennas. We consider the two services Video and Web Browsing and design the beamforming vectors at the BSs. The objective is to maximize the aggregated mean opinion score (MOS) of the users under constraints on the BSs powers and the required quality of service of the users. We also consider extra constraints on the QoE of users to more strongly enforce the QoE in the beamforming design. To reduce the complexity of the optimization problem, we suggest suboptimal and computationally efficient solutions. Our results illustrate that increasing the number of antennas at the BSs and also increasing the number of small cells antennas in the network leads to a higher user satisfaction.

    Optimization of Audio Processing algorithms (Reverb) on ARMv6 family of processors2008Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Audio processing algorithms are increasingly used in cell phones and today’s customers are placing more demands on cell phones. Feature phones, once the advent of mobile phone technology, nowadays do more than just providing the user with MP3 play back or advanced audio effects. These features have become an integral part of medium as well as low-end phones. On the other hand, there is also an endeavor to include as improved quality as possible into products to compete in market and satisfy users’ needs. Tackling the above requirements has been partly satisfied by the advance in hardware design and manufacturing technology. However, as new hardware emerges into market the need for competence to write efficient software and exploit the new features thoroughly and effectively arises. Even though compilers are also keeping up with the new tide space for hand optimized code still exist. Wrapped in the above goal, an effort was made in this thesis to partly cover the competence requirement at Multimedia Section (part of Ericsson Mobile Platforms) to develope optimized code for new processors. Forging persistently ahead with new products, EMP has always incorporated the latest technology into its products among which ARMv6 family of processors has the main central processing role in a number of upcoming products. To fully exploit latest features provided by ARMv6, it was required to probe its new instruction set among which new media processing instructions are of outmost importance. In order to execute DSP-intensive algorithms (e.g. Audio Processing algorithms) efficiently, the implementation should be done in low-level code applying available instruction set. Meanwhile, ARMv6 comes with a number of new features in comparison with its predecessors. SIMD (Single Instruction Multiple Data) and VFP (Vector Floating Point) are the most prominent media processing improvements in ARMv6. Aligned with thesis goals and guidelines, Reverb algorithm which is among one of the most complicated audio features on a hand-held devices was probed. Consequently, its kernel parts were identified and implementation was done both in fixed-point and floating-point using the available resources on hardware. Besides execution time and amount of code memory for each part were measured and provided in tables and charts for comparison purposes. Conclusions were finally drawn based on developed code’s efficiency over ARM compiler’s as well as existing code already developed and tailored to ARMv5 processors. The main criteria for optimization was the execution time. Moreover, quantization effect due to limited precision fixed-point arithmetic was formulated and its effect on quality was elaborated. The outcomes, clearly indicate that hand optimization of kernel parts are superior to Compiler optimized alternative both from the point of code memory as well as execution time. The results also confirmed the presumption that hand optimized code using new instruction set can improve efficiency by an average 25%-50% depending on the algorithm structure and its interaction with other parts of audio effect. Despite its many draw backs, fixed-point implementation remains yet to be the dominant implementation for majority of DSP algorithms on low-power devices.

    Investors and valuers: Similarities and differences from a behavioural perspective2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis is an explorative analysis of the commercial real estate actors. The behavioral theory has revealed many flaws in the neo classical assumptions. This includes models of rationality and prescribed behaviors. Research suggests both appraisers and investor act in ways that can be seen as irrational. Appraisers amongst other things anchor to figures that are not part of the valuation theory and investor invest on bases that are not fundamentally sound. Both also exhibit biases, such as confirmation bias and loss aversion. If valuation does not reflect the way market participants behave then they fail to give us a correct market value. We use interviews to try and understand how appraisers try to reflect the market and to understand how investors and other market actors value properties by comparing their use of the DCF-method. Our results suggest that there are many technical differences between how methods are used by different actors and that appraisers have a too close connection with the market actors.

    The study of urban form in Sweden2009In: Urban Morphology, ISSN 1027-4278 , Vol. 13, no 2, p. 121-127Article in journal (Refereed)
    Abstract [en]

    Early research on urban form in Sweden was undertaken before the First World War. After the Second World War research was influenced by the major criticisms levelled at comprehensive urban renewal and suburban mass housing. These criticisms were particularly on the ground that values embodied in the traditional built environment were being ignored. Increased interest in the study of historical urban fabrics was associated with the development of methodologies reliant on the concepts of typology and morphology. These development were dependent on the activities of individual researchers until the very recent development of wider co-ordinating research organizations.

    Motivationsfaktorer för förändring av våldsbeteende: Tre män berättar om sin motivationsprocess före, under och i slutet av behandlingen2010Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie var att genom intervjuer beskriva olika betingelser som motiverar män att söka hjälp för sitt våldsutövande i nära relationer samt beskriva olika betingelser som är avgörande för om man fullföljer den planerade behandlingen eller inte. Den tredje frågeställning var om de här beskrivningarna kunde ge idéer om vilka behandlingsinslag som bidrar till att män fullföljer behandlingen som syftar till att man slutar använda våld. Tre män intervjuades tre gånger under sin behandling, det vill säga i början, i mitten och i slutet av behandlingen. Intervjuerna genomfördes under sammanlagt sex månader. Intervjuerna följde en intervjuguide och var halvstrukturerade.

    Gemensamt för alla tre män som är avgörande för att de söker hjälp och fullföljer sin behandling är när de upplevde att deras våldshandlingar fick allvarliga konsekvenser både för sig själva och för sin omgivning.

    En annan avgörande motiverande faktor för dessa män var att de upplevde att gruppledarna för behandlingsgruppen gav utrymme för allas berättelser. Männen uttrycker att de får ett utrymme för att själva reflektera över den situation som de befinner sig i utan en alltför styrande, kontrollerande attityd från gruppledarna. Detta förhållningssätt från gruppledarna verkar stärka männens motivation till att fortsätta behandlingen och därmed göra förändringen möjligt.

     Mötet med de andra deltagarna är en central motivationsfaktor för att genomföra behandlingen. Känslan att man inte är ensam, att man delar med sig av sina egna erfarenheter, att man känner igen sig, att se värre konsekvenser för andra deltagare är viktiga faktorer i förändringsarbetet.

    Motivationen verkar vara motorn eller drivkraften i själva förändringsarbetet. Denna undersökning pekar i riktning att motivationen verkligen är en dynamisk och föränderlig process som påverkas av många olika komponenter, inte minst i relation till andra människor.

    Dynamic simulation of solar water heating system using supercritical CO2 as mediating fluid under sub-zero temperature conditions2019In: Applied Thermal Engineering, ISSN 1359-4311, E-ISSN 1873-5606, Vol. 161, article id 114152Article in journal (Refereed)
    Abstract [en]

    CO2 is becoming increasingly important as a mediating fluid, and simulation studies are indispensable for corresponding developments. In this study, a simulation-based performance investigation of a solar water heating system using CO2 as a mediating fluid under sub-zero temperature condition is performed using the TRNSYS® software. The maximum performance is achieved at a solar savings fraction of 0.83 during July. The as lowest solar savingss fraction of 0.41 is obtained during December. The annual heat production of the proposed system under Fargo climate is estimated to be about 2545 kWh. An evacuated glass tube solar collector is designed, fabricated and tested for various climate conditions. Moreover, a detailed comparison of the system's performance at sub/supercritical and supercritical pressures shows that the annual heat transfer efficiency of the modeled system is 10% higher at supercritical pressure than at sub/supercritical pressures. This result can be attributd to the strong convection flow of CO2 caused by density inhomogeneities, especially in the near critical region. This condition resuls in high heat transfer rates.

    Thermal diffusivity of sintered stainless steel-alumina composites2006In: Metallurgical and materials transactions. B, process metallurgy and materials processing science, ISSN 1073-5615, E-ISSN 1543-1916, Vol. 37, no 4, p. 513-518Article in journal (Refereed)
    Abstract [en]

    Thermal diffusivity measurements were carried out as a function of temperature on sintered AISI 304 stainless steel-alumina composites having various compositions (0.001, 0.01, 0, 1, 1, 2, 3, 5, 7, 8, and 10 wt pct Al2O3). The measurements were carried out between room temperature and 1473 K. The thermal diffusivity and the thermal conductivity were found to increase with temperature in all the composite specimens. The thermal diffusivity was found to decrease with increasing weight fraction of alumina. This tendency can clearly be seen at temperatures above 755 K. The experimental results are in good agreement with the simple rule of mixture, the Eucken equation, and the Ohm's law model developed by Hayashi et al. at weight fractions of alumina below 5 wt pct. Beyond this composition, the thermal diffusivity/conductivity shows a large discrepancy from the models. This could probably be attributed to the accumulation of alumina particles during cooled pressing and sintering.

    Property measurements towards understanding process phenomena2005Licentiate thesis, comprehensive summary (Other scientific)
    Abstract [en]

    The main objective of this industrially important work was to gain an increasing understanding of the properties of materials such as CMSX-4 nickel base super alloy, mould powder used in continuous casting of steel and coke used in blast furnace, with special reference to the thermal diffusivities. The measurements were carried out in a wide temperature range, solid, liquid, glassy and crystalline states.

    For CMSX-4 alloy, the thermal conductivities were calculated from the experimental thermal diffusivities. Both the diffusivities and conductivities were found to increase with increasing temperature. Microscopic analysis showed the presence of intermetallic phases such as NiTi and NiTi2 below 1253 K. In this region, the mean free path of the phonons is likely to be limited by scattering against lattice defects. Between 1253 K and solidus temperature, these phases dissolved in the alloy adding to the impurities in the matrix, which, in turn, caused a decrease in the thermal diffusivity. This effect was confirmed by annealing the samples at 1573 K. The thermal diffusivities of the annealed samples measured at 1277, 1403 and 1531 K were found to be lower than the thermal diffusivities of non-annealed samples and the values did not show any noticeable change with time. It could be related to the attainment of equilibrium with the completion of the dissolution of γ and γ´ phases during the annealing process.

    Liquid CMSX-4 does not show any change of thermal diffusivity with temperature. It may be attributed to the decreasing the mean free path being shorter than characteristic distance between two neighbouring atoms.

    On the other hand thermal diffusivities of mould powder having glassy and crystalline states decrease with increasing temperature at lower temperature and are constant at higher temperature except for one glassy sample.

    Analogously, the thermal diffusivity measurements of mould powder did not show any significant change with temperature in liquid state. It is likely to be due to the silicate network being largely broken down.

    The thermal diffusivity is increased with increasing crystallisation degree of mould powder, which is expected from theoretical considerations.

    The coke sample, taken from deeper level of the blast furnace, is found to have larger thermal diffusivity. This could be correlated to the average crystallite size along the structural c-axis, Lc, which is indicative of the higher degree of graphitisation. This was also confirmed by XRD measurements of the different coke samples. The degree of graphitisation was found to increase with increasing temperature. Further, XRD measurements of coke samples taken from different levels in the shaft of the blast furnace show that the graphitisation of coke was instantaneous between room temperature and 1473 K.

    Towards Low-Power Reconfigurable Photonic ICs Based on MEMS Technology2018Conference paper (Other academic)
    Abstract [en]

    With the progress and industrialization of photonic integrated circuits (PIC) in the past few decades, there is a strong urge towards design and prototyping in a fast, low-cost and reliable manner. In electronics, this demand is met through field programmable gate arrays (FPGA). In the Horizon 2020 MORPHIC (MEMS-based zerO-power Reconfigurable Photonic ICs) project, we are developing a reconfigurable PIC platform to address this demand in the field of photonics and to facilitate the path from idea towards realization for PIC designers and manufacturers.

    Bipartite entanglement measure based on covariance2007In: Physical Review A. Atomic, Molecular, and Optical Physics, ISSN 1050-2947, E-ISSN 1094-1622, Vol. 75, no 6Article in journal (Refereed)
    Abstract [en]

    We propose an entanglement measure for two quNits based on the covariances of a set of generators of the su(N) algebra. In particular, we represent this measure in terms of the mutually unbiased projectors for N prime. For pure states this measure quantifies entanglement, we obtain an explicit expression which relates it to the concurrence hierarchy, specifically the I-concurrence and the three-concurrence. For mixed states we propose a separability criterion.
