This report is part of a Bachelor?s degree corresponding to 15 creditsat the Royal Institute of Technology, Stockholm. The work hasbeen carried out by Max Wikander, author of the report, supervisedby Lanie Gutierrez-Farewik and Erik Dijkstra.Gait analysis includes measurement, characterization and assessmentof human movement and is used to assess kinematic or otherabnormalities during gait. Center of rotation and the axis of rotationof a joint are fundamental parameters in motion analysis. However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.

This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.

Predicting corporate failure is an increasingly important topic in the world of economics today. This paper, with the help of the credit ranking company Syna AB, aims to investigate a few different statistic strategies to do just that. This task is accomplished by using a data material of 250 000 Swedish companies divided into two subsamples. The first sample is used to develop the model and the second as a validation sample. The model developing sample holds 160 000 companies divided into five different subgroups based on size and age.

The aim of this master thesis is to investigate the design of the reference service and its development that Internet has caused in college/university libraries when it comes to the service provided to the user. I want to examine the quality of this development from the view of the librarians, and also investigate their attitude and how they deal with this development.The following questions were asked:? How has Internet changed the reference service at college/university libraries?? How do the librarians look upon the possible change of quality in the reference service when the Internet is involved?? What attitude do the librarians hold toward this development where Internet is used in the reference service and how do they deal with it?The method used was qualitative interviews. A total of six librarians from Blekinge tekniska högskola, Halmstad högskola, Lunds universitet and Växjö universitet have been interviewed.The theories and models used were ?media richness?, a quality framework including ?quality aspects of a service?, and social psychology and its ?reasons for a positive/negative attitude on an organisations change?.The result shows that Internet has brought more sources of information and additional ways to contact the library.

Nowadays the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study is a time study with some quality follow ups on a strip-road operated thinning model, a stand-operated thinning model with one intermediate passage between the strip-roads and a stand-operated thinning model with two intermediate passages between the strip-roads. The machines in the study were a small harvester (Forestline MPM C90) and a medium sized forwarder (Timberjack 1110). The study was made in Litsnäset outside the city of Östersund in Sweden and was made during the autumn 2007. In a lodgepole pine stand six study units (0,6 ha) were thinned with the three different models, two study units per model.

The use and attention given to the certification system ?Miljöbyggnad? has increasedin recent years. The system is completely Swedish and was initiated in 2005 by theBygga-Bo-Dialogen. Miljöbyggnad aims to create a healthy indoor environment, reduceenergy consumption and discourage the use of hazardous chemical substances. Thegrades that can be obtained are Classified, Brons, Silver and finally Gold.The work has been to examine three different models and conclude how the designof the models affect the grades in the certification system Miljöbyggnad.

AbstractSAAB has for a long time used user controlled pilot models in ARES. ARES is a simulation tool used in the desktop environment for simulations and calculations of the JAS 39 Gripen fighter and other aircraft. ARES stands for ?Aircraft Rigid body Engineering Simulation?. To work with these pilot models has been both time-consuming and inefficient.

The aim of this work is to demonstrate how the net present value (NPV) at the time of the first thinning depends on the spacing after pre-commercial thinning, and show how net value from first thinning in same stand is influenced. This study is performed with models based on non-distant dependent growth models for single trees. Two different growth models have been used, one for cleaning (pre-commercial thinning) and one for thinning. The first one yields stem density distributed over diameter classes. In the second one, (the thinning model), it is possible to choose when thinning should be done, the thinning method, thinning grade and numbers of thinning.

This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.

To start a company on the Internet is something that has appealed a lot of people during the last couple of years. Some of the companies have succeeded in their struggle but a lot of companies have failed to live out their ambition. This paper deals with the concept of e-commerce and aims to study whether or not the companies that has succeeded has made use of business models and what other factors that is important that you wont find in any written theory.The paper also aims to study the concept of business models and what a business model consists of. To be able to do this research we have interviewed three different companies that are all active in e-commerce and have survived for at least three years. Two of the companies are classical web shops that sell products to their customers and the last one is a site with articles about hardware and IT business in general.

Background: Of those who start companies, only about 30 % are women. Women's companies also often have both fewer employees and lower turnover. Several efforts are therefore being made to try to influence and encourage more women to start businesses and to get them to expand. Two of these ventures are special network for women and about women entrepreneurs as role models, something that also the theories believe is very important for a more egalitarian business. While entrepreneurship is encouraged for growth in the community, it also has a male character, something that needs to be considered.Purpose: As both the EU and the Swedish government through measures such as Tillväxtverket, is investing large sums to promote networking and role models, we intended to analyze the importance of networking and role models for entrepreneurial women.

ABB FACTS designs equipment and plants for series and phasecompensation.This thesis has been performed at ABB FACTS on the Mechanical Design (DM) department inVästerås, Sweden. The purpose of the thesis was to develop and design calculations andsimulation tools for ABB FACTS?s standard series capacitor platforms.

Eco-design is all about improving products environmental performances throughout the products lifecycle by including the environmental aspect into the product development process. There are a large number of different tools that can be used for this, but there are several factors that can affect which one will be the best to use. Some tools for eco-design takes comprehensive studies and can only be performed by experts, while some tools can be used more time- and cost efficient and with basic knowledge. The choice of tool should be based on the company?s situation.This report describes the research of how the design and furniture company Blå Station could include a tool for eco-design in their product development process.

In our essay we examine the different introduction models that are practiced in preschool. The central question is if the different models have any importance (or consequences) for the children?s connection in preschool. In the two different cases we will present, one based upon preparatory training that was applied during the 1990s and another that is currently used today.The purpose with this essay was to get a deeper understanding for the child?s attachment to preschool and for how we, as educators should act during the preparatory training to create a secure foundation for the child.
