Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.

This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.

The essay initially intends to find adequate models to describe and forecast monthly data for the Swedish Consumer Price Index sub group Clothes and Shoes 1986-2005. The time series observations during 2006 are considered ?out of sample period? which is used to evaluate the forecasts. The purpose is to perform time series decomposition and to investigate and analyzethe seasonal pattern. The Box-Jenkins approach is used to find adequate ARIMA models.

The main purpose of this study is to investigate the productivity effects of multiple tree handling in thinnings. Other important elements have been to investigate in which extent multi-tree handling is used in stands with different stem volumes and the impact of collecting partially delimbed fuelwood assortments has on harvesting performance. The study is based on data from thinnings in Sydved and contractors' operating activities. Collection and compilation of operating schedules, number of stems and surveyed volumes from several contractors and a large number of executed orders underlying the results. Multiple tree handling is used to a much greater extent at lower average stem volumes. Prediction models for productivity of the multiple-tree handling harvesters in the study differ from the productivity models for single-tree handling. In the model developed in this study productivity is not as dependent of stem volume as reference models.

The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.

In the end of the 80´s the area of system development moved into a new era. As a consequence many new methods and development models emerged which in many cases resulted in problems when choosing system development models and methods. As a result of these problems the today standardized modeling language UML (Unified Modeling Language) was created. UML is tailored to support many different types of projects. This is possible because of UML?s capacity to be adjusted and adapted to a specific company environment.The purpose of this bachelor thesis is to investigate how and why companies use UML and what experiences and opinions those who use UML have of using UML in practice.

Background: The interest in shares has increased over the years, despite several stock market crashes. One reason for this is the emergence of stock trading online,which makes it easier for individuals to trade in shares. However, there has been much criticism towards financial analyst with the lack of fundamental basis to support their recommendations.Objective: The purpose of this study is to examine the share valuation models swedish financial analysts today applies and consider appropriate. A comparison will also be carried out in previous studies, to see if the application of the modelsand their suitability has changed.Method: The study used a qualitative approach with deductive approach. Semistructured interviews were conducted and the basis for the study's primary data.The theories and previous studies obtained through secondary data.Results: Our results demonstrate that no single model applied, is appropriate.

Businesses role in society is changing. Corporations are expected to take responsibility, not only for their traditional business conduct, but also for social and political issues. A rise in globalization and international trade has led to an increased interest in the concept of CSR. Accordingly, stakeholders are expecting multinational companies to be accountable for existing issues in developing countries. New business models are needed to meet increased expectations of responsibility and shared value creation. Based on an understanding of the need for new business models a multinational corporation is studied in a local context, where a radically new way of doing business is developed.

Due to increasing international competition and new technology IT-consultants has been forced to oversee their business models lately. The main purpose of this study is to investigate the process and consequences of a shift in business model for a consultant by using a methodology based on action research. The empirical foundation consists of a field study with observations, notes, interviews and business related documents. The case describes a consultant?s process of shifting business model from profits based on man-hours to selling a standardized system.

Prostitution has for a long time been an understudied field in economics. Due in part to a lack of quantitative and empirical material, itself largely a result of the illegality or semi-illegality of the activity in most countries, the factors that explain the prevalence of, and pricing in, prostitution have remained largely undiscussed. In the last 20 year, this have begun to change: new theories ? notably by Edlund & Korn (2002), Rao et al (2003) and Della Giusta et al (2009) ? have been formulated and the rise of internet based escort sites have made large scale quantitative studies possible. This thesis examines if, and in what way, court documents can help expand the understanding of the economics of prostitution in Sweden.

When nursing human patients during hospitalization, the nurse is the one responsible. The nursing is controlled by different models of nursing and careplans, shaped by every patient?s individual needs. This is to guarantee the quality of the care. The veterinary nurse is not ultimately responsible for patient care.

Transfer pricing innebär i grund och botten att den vinst som företagsgrupper får ska fördelas på ett korrekt sätt mellan deländer där gruppen har aktörer.Armlängdsprincipen är den internationellt accepterade tillvägagångssättet att fastställa priser när närstående företag handlar medvarandra. Principen innebär att företagen ska handla med varandra precis som om de vore oberoende företag, påarmlängdsavstånd.Immateriella tillgångar har en rad egenskaper som gör dem speciellt svårvärderade ur armlängdsperspektiv. Marknadsvärdetbehöver inte vara samma som värdet för ägaren. I regel finns det heller inga transaktioner som innefattar immateriella tillgångarvilket gör det svårt att få en lämplig armlängdsvärdering med hjälp av de tre traditionella metoderna.De två vinstbaserade metoderna (Profit Split Method och Transactional Net Margin Method) är de mest lämpliga för atttillgodose armlängdsprincipen. Profit Split Method:s kanske största fördel är att man för att använda metoden inte behöver hajämförbara transaktioner till hands.

This reports goal is the give BSR AB more information that's useful towards their customers in marketing of their products.It involves tests of different air filters designed for cars and 3D-modelling of Opti-Flow systems. The three models thats being tested is SAAB (93SS), VAG (1.8T) and Volvo (S60). To every brand there are three different models. A orginal- , sport- and an open cone air filter (Opti-Flow).The results indicate that the open Opti-Flow filter has better performance compared to the other cased filters. The sport filters for SAAB and Volvo has better performance then the original filter.

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.
