In this work, I describe the factors that affect the bucking of pine logs on the basis of the machine operator. The aim is to find an explanation why the bucking differs so greatly between requested length results and the actual length results in pine bucking. The used methods in this study were data from simulated pine outcomes, data from earlier length outcomes and analysis of the harvesters' PRI files. This is to identify the problem. To explain the background to the problems a qualitative research interview was used.

I rapporten undersöks vilka möjligheter användarberoende vyer av XML-data kan ge i webbmiljö. Undersökningen omfattar dels att ta reda på vad en användare vill ha möjlighet att kunna visa eller påverka i en dynamisk vy, och dels vilka av dessa egenskaper som kan uppnås med hjälp av stilmallar i XSL. Med dynamiska vyer skall det gå lättare att förändra och skapa rapporter som passar den enskilde användarens behov, det vill säga en mer lättläst och överskådlig version. Vad som framkommer av rapporten är vilka egenskaper som en användare vill ha i en dynamisk vy. Ett antal existensbevis i form av exempel visar också vilka av dessa som går att lösa.

Företaget Nethouse har haft uppdraget att kravställa, utveckla och implementera ett verksamhetssystem åt Sveriges  Skorstensfejaremästares Riksförbund (SSR). Medlemsföretagen i SSR bedriver sotarverksamhet på uppdrag av Sveriges kommuner och är beroende av insamlad data kopplad till deras verksamhet. I det nyutvecklade systemet, som går under namnet Ritz, samlas informationen i en central databas och är tillgänglig för flertalet intressenter med hjälp av ny teknik och modernare lösningar. Systemet är helt webbaserat och körs som en molntjänst, tillgängligt via antingen en webbsida eller som mobilapplikation. Åtkomsten av data baseras på företagsnivå på ?stämplad? data i databasen och för att reglera åtkomsten för företagsanvändare till respektive företags data används rollbaserad åtkomstkontroll.Detta examensarbete har syftat till att utveckla en prototyp till en beslutsstödslösning för dynamisk åtkomst till de datamängder som lagras inom Ritz.

A study of communication content, frequency and problems was performed at the Swedish Air Force Air Combat Simulation Centre, FLSC. The purpose was to investigate the connection between team communication and performance variables, to study communication problems during air combat and to employ and develop the PILOT method of communication problem analysis. Ten fighter pilots and four fighter controllers engaged in simulated air combat beyond visual range in teams on two sides, Blue and Red, with four pilots and one fighter controller each. Eight such training runs lasting 15 to 25 minutes were analyzed with regard to the Blue team?s communication during launch situations, i.e.

This study aims to evaluate the waste management in Norrbottens municipalities in key areas such as possibilities to reach the two national waste goals, information to the public, the effect of legislation, future of waste management and differences in geographic- and demographic areas. The Waste Framework Directive (WFD) issued by the EU and incorporated into Swedish law plays a major part in waste management by defining a hierarchy in five steps how waste should be treated. Interviews conducted with each of the fourteen municipalities aimed to find out what step in the hierarchy they are at and what effect the implementation of EU-legislature into Swedish law has had. Based on the interviews a diverse range of answers was found in relation to the questions asked, generally the more populated municipalities saw a more positive future of waste management, mainly because more developed infrastructure to handle waste is already in place. However the smaller the municipality is the harder it is to allocate resources for waste management and problems arise in the form of expensive transports of waste.

Dagmar är en av de mest förödande stormarna, som med sina 4-5 miljoner kubikmeter vindfälld skog präglat skogssverige det senaste årtiondet. Skogsbolaget SCA förlorade stora mängder skog den 26 december 2011 till följd av stormen. Två av trädslagen på SCA:s marker är tall och contortatall, med olika förutsättningar vad gäller förmåga att motstå stormvindar. Tillhandahållna data kom från SCA:s inventering före Dagmar, under åren 2007-2011, respektive efter stormen, i februari-mars 2012. Inventerat data har sammanställts, bearbetats och analyserats i Microsoft Office Excel, MiniTab 16 och ArcMap 10.1.

The aim of this master thesis is to examine the identity of librarians. We have done this by conducting a text analysis where we have analysed texts produced by DIK, the major union of librarians, and by Library and Information Science departments in Sweden. The material we have analysed is texts produced in the aim of introducing and marketing the librarian occupation and education. The aim of this study is to find out how the identity of the librarian is expressed in this material. We have conducted the text analysis by adopting the critical discourse analyst Norman Fairclough´s theories.

I denna rapport undersöktes S&P 500 Energy Index genom multipel regressionsanalys. Modellerframställdes genom regression och baserades på data hämtad från börsen. Modellerna angavs iprocentuell ändring respektive absolut ändring. Validitet för varje enskild kovariat testades och en risknivå avgjorde om en kovariat skulle inkluderas i modellen eller inte. Detta ledde till två modeller med bättre kurvanpassning till den givna mängd data över det valda energiindex.

Webbaserade informationssystem är idag en vanlig metod för företag att effektivisera sin verksamhet. Genom att använda sig av webbapplikationer så som web-services, kan resurser och data enkelt delas inom företaget på lokal och även global nivå över internet, genom att dessa resurser och data hämtas via web-servicen från centrala databaser. Examensarbetet utfördes hos Syntronic Software Innovations (SSI) i Gävle och det är utifrån deras specifikationer och krav som systemet har utvecklats. Denna uppsats redogör för hur ett sådant webbsystem kan utvecklas, samt vilka tekniker och verktyg som finns tillgängliga idag lämpar sig bäst för ändamålet. För att kunna svara på dessa frågor kommer forskningsmetoden design science att användas.

In February 2002 the European commission put forward a proposal for a new directive on The patentability of computer-implemented inventions, but which during my work on this essay has not been decided on yet. The directive has divided the decision-makers in the union, the commission and parliament, into two different positions regarding by which range computer-implemented inventions should be patentable. The parliament has amended the commissions proposal in a substantial way and the legal process has caused a heated debate both within the unions administration and among various interest groups both in favour of and against a patent on computer-implemented inventions. The loudest protests have come from a group that feels threatened by a possible software patent: Open Source. In this study I examine both the arguments by the decision-makers and by the lobbying for and against the proposal.

Platelet transfusions can be necessary during treatment of patients with thrombocytopenia or impaired platelet function. Platelet function in platelet concentrates (PC) deteriorate with storage time. Studying swirling is often used to control the quality of PC?s before transfusion but the method has some disadvantages. Therefore other methods can be useful, for example impedance aggregometry (IA, Multiplate® Analyzer) to measure platelet function.     In this study the change in platelet function over time was examined in buffy coat and apheresis platelets with IA where aggregation had been induced with adenosine diphosphate (ADP) and collagen.

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

Three methods of sensitivity and unceartainty analysis have been applied to the operative stormwater- and recipient model StormTac. The study area is the watershed of lake Flaten in the municipality Salem. StormTac?s submodels for stormwater, pollutant transport and the recipient are cosidired. In the sensitivity assessment, the model parametres and inputs were varied one at a time by a constant percentage according to the ?one at a time? (OAAT) method and the response of the outputs were calculated.

National and international studies, such as PISA and TIMSS, which are part of the national evaluation system, are carried out continuosly. Skolverket, in collaboration with researchers, are responsible for the implementation, evaluation, and analysis of the studies. National results show an increasing percentage of pupils who do not reach the goals in mathematics. The last completed international studies PISA 2009 and TIMSS 2007 show an impaired trend of knowledge, in international comparison. Moreover, studies also show that the differences between schools and also within the same school in Sweden have increased.

Testing and analysis of measurement data is a major part of the workday for development engineers within the section Fluid and Emission Treatment to assure the quality of products developed by Scania CV. The ineluctable variation and therefore uncertainty of results can be quantified and discussed with the use of statistical methods.The overall objective of this study is to examine how the competence of development engineers can be improved within the area of statistics. This has been done by relating the concept of competence with the use of statistical methods to analyse experimental data and by investigating which factors that influence the competence of the engineers. Observations of the daily operations, interviews and a focus group with development engineers and a workshop with management personnel, has been used as research methods in this study.The results show that the desired competence, from the perspective of the individual, consists of knowledge, motivation and support. It is important that none of these parts are neglected when the competence of engineers is to be strengthened.
