Energismart modulhus med takintegrerade solceller
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.
Kunskap, motivation och stöd : En studie om kompetensutveckling inom statistisk analys av experimentella stöd
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.

JÀmlik strokevÄrd : En analys av skillnader mellan patientgrupper avseende vÄrd pÄ strokeenhet, Ären 1995-2009
The main objective of this study is to divide a number of colorectal cancer cases into subgroups based on their molecular features using cluster analysis. The data used is supplied by a research group at Pathology, the Department of Medical Biosciences, UmeÄ University, and consists, after some preparation, of 455 observations which is a larger data set than many similar studies. The molecular variables that the clustering is based on are CIMP (CpG Island Methylator Phenotype), MSI (Micro Satellite Instability), BRAF- and KRAS-mutations. These are categorical variables and consequently the clustering method used is PAM (Partitioning Around Medoids) which is particularly useful with data on diverse variable level. The final analysis results in four subgroups that are represented by different combinations of attributes on the aforementioned variables.
BIM vid installationsprojektering
Planet rendering plays an important role in universe visualization and geographic visualization. The recent tools and methods allow better data acquisition, usually with very high resolution. However in computer graphics, there is always the limitation on the resolution of geometry and texture due to numerical imprecision. Not many applications can handle high resolution data effectively.This thesis introduces, Implicit Surface Scene, a level of detail scene management inspired by dynamic coordinate system and SCALEGRAPH? which change over time depending on the current camera position relative to the planet surface.
Striving for innovation; working in CFT - a case study of Audi
The purpose of this thesis is to study and determine how working in cross functional teams can generate value in an effort to facilitate innovation. An inductive scientific perspective is chosen as the research approach. A single case is investigated with the theoretical framework based on Resource Based View, Intellectual Capital, Innovation theory and theories concerning Cross Functional Teams. The empirical material has been collected through primary data; surveys, interviews and secondary data; literature, websites and further complementary data. The practice of using Cross Functional Teams will enhance organizational learning, knowledge transfer, increase communication and innovation, which in turn will increase the speed and performance of the new product development process.
Asymmetriska rÀnteeffekter : en empirisk studie av styrrÀnteförÀndringar
Det senaste halvÄret har Sveriges styrrÀnta sÀnkts kraftigt för att stimulera den avstannande ekonomiska aktiviteten. Enligt makroekonomisk teori ska en ökning respektive sÀnkning av rÀntan pÄverka konsumtionen likvÀrdigt, i respektive riktning. Men fungerar verkligheten som den ekonomiska teorin pÄstÄr? Tidigare studier pÄ utlÀndsk data har kunnat pÄvisa ett asymmetriskt rÀntesamband medan forskning pÄ svensk data saknas. Med hjÀlp av en felkorrigeringsmodell, skattad med Engle-Grangegrs tvÄstegsmetod, testas detta.
FÄglar i urbana miljöer : kvaliteten pÄ urbana habitat och om bestÄndstÀthet Àr ett bra mÄtt pÄ habitatkvalitet
The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.
Avrundar företag sina resultat - En studie av Cosmetic Earnings Management i Sverige
The aim of this thesis is to examine the occurrence of Cosmetic Earnings Management (CEM) among Swedish companies. CEM refers to the small upward rounding of reported net income to reach cognitive reference points. Important cognitive reference points are multiples of ten (N*10^x) of reported net income and rounding towards these has been documented in other markets around the world over the last 20 years. The occurrence of CEM on the Swedish market is studied using digital analysis, frequency testing and Benford's law. Firstly, reported net income of publicly traded companies between 1996 and 2010 is examined.
Genetic variation in dairy cattle claw health traits recorded by claw trimmers
Claw health has been recorded by claw trimmers at trimming in Sweden since 1996, but data was then captured at each AI association. From 2003 data was captured by central scanning and entered directly to the national cow data base at the Swedish Dairy Association (SDA). This reporting was introduced because SDA wanted to be able to use these records to improve dairy cow claw health by breeding. It is desirable with cows that have healthy claws, because poor claw health can contribute to impaired production and fertility.
The claw health report begins with some information about herd, claw trimmer, date et cetera and continues with the part where the claw health is recorded. Here the ID of each cow is filled in and on the same row the conditions for dermatitis, heel horn erosion, sole haemorrhage and sole ulcer are recorded as no lesion (blank), slight lesion (/) or severe lesion (X).

Patienters livssituation och vÄrdkostnad
The purpose of this paper is to test a procedure that would be useful for a certain, more final purpose. Assume that you want to know if the differences in the result of a certain effort in health care have any connection with differences between the life situations of the patients. This would be easier to investigate if the life situations of the patients had connection to the easily available variable Health Care Cost (in Swedish VK). In that case the searching for connections between VK of patient groups and the result of health care efforts would be sufficient to gain knowledge of possible connection between health care efforts and life situations. Thus that is the final purpose.
