Examensarbetet använder generaliserade linjära modeller för att identifiera och analysera enhetsspecifika egenskaper som påverkar risken för operativa förluster. Företag exponeras sällan mot operativa förluster vilket gör att det finns lite information om dessa förluster. De generaliserade linjära modellerna använder statistiska metoder som gör det möjligt att analysera all tillgänglig interndata trots att den är begränsad. Dessutom möjliggör metoden att analysera frekvensen av förlusterna samt magnituden av förlusterna var för sig. Det är fördelaktigt att göra två separata analyser, oberoende av varandra, för att identifiera vilka enhetsspecifika egenskaper som påverkar förlustfrekvensen respektive förlustmagnituden.

This thesis is written at WSP management and investigates the practice of pre-project planning and feasibility studies at Swedish construction companies, through the study of the ongoing feasibility study of the mall Sturegallerian in Stockholm, and through interviews with experienced project managers in the construction industry. There is currently a big span in the way Swedish construction companies plan the pre-project phase and the aim of this thesis is to present a more generic and standardized way that helps minimize project risks and maximize efficiency and profit. The result is a generic model which can be used in pre-project planning. The model describes the phases in the preproject planning process and the activities that span these phases. Is also describes the categories of professions that need to participate in the preproject planning group and which activities that each profession executes. The other result is a list of factors that need to be considered for a well performed pre-project phase, as found during the interviews. Among others the thesis stresses the importance of involving the client as a key participant in the process.

The world today is experiencing an AI summer, urging us to engage with its technologies on a daily basis. Recently, researchers have begun to voice concerns about the potential risks if we do not address the inherent biases in these systems. After all, AI is merely code based on mathematics produced by humans. This essay focuses on Stable Diffusion and Midjourney to examine biases in fashion representation and how fashion is visualized and reproduced concerning race, social class, and culture. A series of prompts were intentionally written in simple terms such as ?rich,? ?poor,? and ?race.? The results revealed troubling biases, as these programs consistently depicted poor individuals as people of color and portrayed wealthy, elegantly dressed individuals as exclusively white..

Syftet med denna uppsats är att undersöka hur inkomstspridningen och inkomströrligheten i Sverige utvecklades i början av 2000-talet. Särskilt fokus läggs på att följa utvecklingen för den del av befolkningen som har lägst inkomster.Resultaten visar att både realinkomster och inkomstspridning har ökat i Sverige under det tidiga 2000-talet, även djupet av fattigdom mätt som avstånd till fattigdomsgränsen har ökat. Med hjälp av logistisk regression med oddskvoter undersöks vilka individer som hade störst chans att lämna fattigdom 2005. Dessa individer var framförallt unga, svenskfödda, de som blivit sambo mellan åren, de med arbete eller som fått arbete och de vars barn lämnat hushållet. De som löpte högst risk att hamna i permanent fattigdom var utlandsfödda, ensamstående, arbetslösa och de som fått fler barn i hushållet..

Micronic Laser Systems AB produces and develops machines for the photo mask production market. One of their products is the Omega machine which exposes photo masks using 5 laser beams simultaneously. It is important that the distance between the each laser beam, the x-separation, is the same. The x-separation is today measured by exposing a photo mask with a certain pattern and thereafter measured with a metrology system. This takes to much time and it is desired to find a faster method to measure the x-separation without loosing precision.The task for this master thesis is to improve an existing measurement method which uses a calibration mask.

This thesis discusses the 2007 elections in Kenya, and its aftermath. The aim is to examine whether or not ethnicity played a major role in the outbreak of violence that followed the referendum. As well as different theories and discussions on ethnicity, I will also try to explain the course of events by using theories of increased civil violence during a democratic transition, and the fact that weak political institutions can cause violence. My conclusion is that ethnicity has played a part in the violence, but is too simple to blame the events following the election on just that. A number of different factors all contributed to the outbreak, but all to a different extent.

This thesis investigates how inventory management is practiced at a Swedish sawmill company, how practice differs from theory in this field and how the company could make more use of this theory. To do this we have performed a study on relevant literature and compared our findings with a field study on Moelven Valåsen AB. Our analysis shows that a large gap between theory and practice exists. We identify several reasons to this, including some sector specific problems when calculating cost rate for timber inventories. Suggestions on solutions to these problems and an example of how a cost rate can be estimated with relatively simple means are presented.

In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.

Master thesis in Business Administration, Swedish Business School at ÖrebroUniversity, spring semester 2012Authors: Anders Oskarsson & Christian UhlanderTitle: I?m going to make you rich! -With a little help from PiotroskiResearch objective: This paper examines whether a simple account-based analysis strategy,F_SCORE, can improve returns earned by an investor. The results show that F_SCORE generated a69,7 % annual return between 2001-2010 at the Swedish market, which was better than the furtherdeveloped model A_SCORE. Overall, the evidence suggests that the market does not incorporatehistorical information into prices in a timely manner.Methodology: The foundation for this thesis is based on a quantitative approach and empiricalmaterial is gathered from Thomson Reuters Datastream for the Swedish market..

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

Theories about exposure and risk-taking in an everyday environment show a connection between parental strategies, parent-child relationship and exposure on the Internet. In the present study, the Internet is presented as an everyday activity. Negative exposure is seen as an outcome of risk-taking. The purpose of the study was to examine in what way parental strategies together with the parent-child relationship were related to the teenagers? negative experiences on the Internet, which consisted of three categories: 1) Exposure to pornographic sites, 2) Exposure to upsetting and violent material, 3) Digital bullying.

Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.

This thesis examines how knowledge management professionals use trust as a component in the creation of knowledge management systems, and what methods they use for building trust.Adopting a grounded theory approach, interviews with 8 knowledge management professionals active in different industries served as the base for an analysis that identified trust to be the single most important common factor in the data. The concept of trust used by the informants was identified as relating to the knowledge management system itself, rather than other users, employees or groups in an organisation.Building trust, the KM-professionals mainly focused on three methods: simple solutions, system superiority, and implementation security. Using these methods, the KM-professionals seek to ensure system trust by creating opportunities for users to obtain positive experiences of using the system, and thereby generate a foundation for a trust-based relationship between the user and the system..

A wastewater treatment plant has the task to refine the wastewater from substances that should not be released into the environment. The decomposition process can, in a simple way, be described as follows: micro-organisms breathe oxygen and eat unwanted substances. The environment in which the micro-organism lives is known as sludge and the correct amount of oxygen available in the sludge is important for the decomposition to be effective. The oxygenation of the sludge alone stands for about 30% of the plant?s energy consumption.

Sara Lidman?s second novel Hjortronlandet (1955) unfolds in the north of Sweden in the early 20th century. It describes the progress of modernity and the conflicting interests of an old local culture and a new more ?civilised? one. The two cultures are constituted by different value systems and in the novel they are represented by two neighbour communities.
