Clustered Columnstore Indexes (CCI) and In-Memory Online Transaction Processing (OLTP) are two new techniques that were introduced with Microsoft?s new database management system SQL Server 2014.The thesis analyzes these two techniques, describes the theory behind them and also the background information that needs to be known to understand more of the new techniques. Performance tests of the new techniques have been performed to see how much faster response time we can get and less storage we need to use where the result is represented by performance diagrams and a compression diagram. This thesis is a cooperative work with a company called Trimma and the result is used as support to decide if these new techniques could be of advantage for the company.The test consists of five test queries with different purposes. The result is illustrated by diagrams that show the result and another diagram that shows how much the data gets compressed with the different techniques.

Idag är turismen en av världens största näringar och den förväntas växa ytterligare framöver. Turismen bidrar på många sätt till den ekonomiska utvecklingen världen över men effekterna av tillväxten kan även få förödande konsekvenser för miljön. En ökad miljömedvetenhet inom turismbranschen har på senare tid resulterat i olika miljöledningssystem och miljömärkningar. En miljömärkning är Svanen som bildades som ett svar på den ökade miljömedvetenheten i samhället. År 1988 beslöt sig det Nordiska Ministerrådet att utreda möjligheterna att införa en frivillig nordisk miljömärkning.

BakgrundUnder de senare åren har ett flertal länder drabbats av bolagsskandaler som bidragit till en snabb utveckling inom corporate governance. För att förhindra liknande skandaler har mer eller mindre frivilliga regler för bolagsstyrning införts, så kallade koder. Bolagsskandaler har även inträffat i Sverige och 1 juli år 2005 infördes svensk kod för bolagsstyrning. Koden skall bidra till förbättrad styrning av bolag, stärka konkurrenskraften och främja förtroendet på kapitalmarknaden.SyfteUppsatsens syfte är att beskriva och analysera om roll- och ansvarsfördelningen har förändrats mellan bolagsorganen efter införandet av svensk kod för bolagsstyrning.GenomförandeDenna studie bygger på kvalitativ metod och tio intervjuer har genomförts. Intervjuer har skett med representanter från ägare, styrelse, bolagsledning, revisor samt respondenter med god kunskap inom bolagsstyrning.ResultatStudien visar att svensk kod för bolagsstyrning inte har haft någon större effekt på roll- och ansvarsfördelningen.

Debatten om Corporate Social Responsibility (CSR) är aktuell. Att ta socialt ansvar handlar om frivilliga åtaganden för företag, eftersom det går utöver de tekniska och lagliga krav som ställs. Syftet med denna uppsats är att utreda hur CSR tillämpas i de två svenska klädföretagen Hennes & Mauritz (H&M) och Dem Collective. Vi undersöker om och hur företagen upplever kunders krav på socialt ansvarstagande samt om och hur företagen försöker påverka sina leverantörers CSR-arbete. En kvalitativ studie i form av intervjuer har utförts för att få en djupare förståelse för hur de båda företagen bedriver CSR-arbete.

Male piglets have been castrated for centuries to avoid contamination of their meat with boar taint, a strongly unpleasant odour that makes the meat inedible. Today boar taint can be prohib-ited by vaccination against gonadotropin releasing hormone (GnRH) using Improvac®. The aim of this study was to evaluate the efficiency of vaccination on growth performance and behaviour of vaccinated male pigs compared to surgically castrated male pigs. The effect of two feeding regimes, restricted (SLU-norm) and semi ad libitum, was also included in the study. At birth, pigs (n=206) were randomly allocated to the two treatment groups; surgically castrated and vaccination.

The thesis analyzes two different approaches towards responsive web design, Mobile-first and Desktop-first. Responsive web design is a concept for websites whose design is customised based on the screen size. The analysis is performed by collecting views on the methods and also analyzing the usage of mobile and desktop internet to create a prototype of a responsive website where both methods are beeing used.The main difference between the methods is the foundation, where one is designed for mobile and the other for desktop. The thesis indicates that Mobilef-irst gives a better result for the mobile, which unlike the computer has poor performance, smaller screen and poor internet connection, therefore an advantage for the device that needs more focus to maintain a fast response. Desktop-first does not take this opportunity, but focus instead on the computer where the performance is better, which leads to a unnoticeable difference in response time.

Syftet med studien var att med en experimentell design undersöka ifall individens tro på sin förmåga, d.v.s. self-efficacy påverkar utfallet av idrotts prestationer. Detta undersöktes genom att manipulera self-efficacy i en bänkpressövning och därefter mäta eventuella prestationsförändringar under tre sessioner. 21 deltagare (10 kvinnor, 11 män, M = 23, SD = 2.95) med lite eller ingen tidigare erfarenhet av styrketräning deltog. Deltagare delades slumpmässigt in i tre grupper: (LG) lättare vikt än deltagarna trodde, (TG) tyngre vikt än deltagarna trodde och (KG) kontrollgrupp, vikten överensstämde med deltagarnas uppfattning.

The high debt levels experienced in European Countries have lead to academic interest in the deficit bias -the tendency for governments to run budget deficits and accumulate debt. In part one of this thesis a surveyof the economic literature on the origins and solutions to the deficit bias are conducted. The proposedinstitutional solution to the deficit bias in the form of Fiscal Policy Councils (FPC) are outlined and existingEuropean FPCs presented. Based on the works of Calmfors and Wren-Lewis (2011) the EuropeanCommission (EC) is defined as an FPC. Based on this survey, two hypothesis are formulated: (1) theforecasts of future macro-economic events and fiscal performance will differ between the national FPCs andthe national government.

To become a successful athlete requires several different components in which one of themost significant is the ability to develop their own physical strenght. What weight exercises has the best transfer effects for skating?Participants in the study were 20 male senior hockey players from Div. II in the Västra Gö- talands Regionen in which all participants had at least 10 years of hockey experience.Test subjects had to perform a five-minute individual warm up followed by an opportunity to familiarize with the upcoming exercise. The first on-ice test was a 35 meters sprint test and the second test was an S-cornering agility test.

For systems with multicore processors contention for shared resources is a problem that occurs when several memory-intensive processes are executed in parallel within the same memory domain. This contention has a direct influence on the performance of the system and is a complex problem that has been recognized for a long time. An attractive and actively studied way to minimize this problem is by using a process scheduler adapted to allocate processor cores in a way such that contention for shared resources is minimized.With the introduction of multicore NUMA-systems (Non-Uniform Memory Access) the situation has become even more complex. In these systems the access time for processor cores to different memory domains vary depending on factors such as distance and load. Thus, the process scheduler also has to consider where the memory of each process is placed to minimize the distance and balance the load on each memory domain.This report presents a user-level process scheduler for a NUMA-system based on the multicore processor Tilera TILEPro64.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

Forskning hävdar att endast ett fåtal av styrelseledamöterna förstår vilka beslut som är värdeskapande för företaget. En av orsakerna är oförmågan att rekrytera rätt personer och flera röster har höjts för att en diversifierad rekrytering till bolagsstyrelser är en möjlig lösning på problemet. Diversifieringen kan ske utifrån olika demografiska faktorer som på en aggregerad nivå ska medföra att processen från beslut till genomförande blir effektiv. Vi finner stöd för en ökad diversifiering hos styrelsen i en rad teorier som alla är en del av tankegodset inom bolagsstyrning.Syftet är att konstruera och applicera en teoretisk modell för en lönsam styrelsesammansättning utifrån existerande forskning. Studien begränsar sig till svenska bolag på OMXS30 under tidsperioden 2003 -- 2014.Med stöd av vår modell visar vår analys att styrelsens storlek uppvisar en positiv korrelation med företagets förmåga att generera avkastning på eget kapital.

This master thesis has been written in collaboration with Science Park Jönköping and is based on a problem related to corporate innovation. Science Park Jönköping believes that there is an untapped potential in existing industry in the form of ideas that are never commercialized. These theories are also supported in the research in which other authors have perceived that the ideas and inventions which do not belong to the core business risk ending up in drawers. If more of these ideas could be spin-offs or other forms of enterprise instead of staying in the drawers it would lead to growth, both for companies and for the society in large.The purpose of the thesis work is to, based on the case Science Park Jönköping, analyze how science parks and incubators can support the commercialization of ideas that derive from industry, who otherwise had been left lying. The work began with a mapping of the Science Park Jönköping operations and the skills they possess, and then other initiatives that aim to commercialize more ideas from companies were examined.

To render outdoor scenes with lots of vegetation in real time is a big challenge. This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to mathematically generate and render vegetation in real time, with implementation in the scene graph Gizmo3D. The most important quality of the method is its ability to render scenes with many unique specimens with very low aliasing.
