This master thesis deals with steel girders subjected to patch loading caused by concentrated moments. There exist no good methods to calculate by hand the ultimate resistance for this load case. In ?tunnplåtshandboken?, (Handbook for sheet metal, which is published by SSAB), one calculation method is presented. It?s however fairly difficult to use, because of many calculation steps and many graphs.

Chunks and Tasks is a programming model based on the C ++ programming language. This programming model is used for electronic structure calculations, among other things.The purpose of this project is to improve the CHT-MPI software library for Chunks and tasks, so that calculations of matrix-matrix multiplications are performed more efficiently than they do with the existing software library. The software library is based on the work stealing method, which is a method the software library for Chunks and Tasks uses for the distribution of the calculation work. The considered way to improve the software library is by modifying the work stealing method in a way that makes the distribution of calculation work happen in a more efficient way , which will lead to calculations performed faster than before.Two different modifications of the work stealing method were tested and it led to two new methods, Method 1 and Method 2, which distributed the calculation work differently. Method 1 did not give results that were compatible with the theory, since the calculation time with this method was much longer than the previous method.

In a comparing survey this thesis investigatesclassification systems for dams in Sweden, Norway,Finland, Switzerland, Canada and USA. Theinvestigation is aiming at an understanding of howpotential consequences of a dam failure are takeninto account when classifying dams. Furthermore,the significance of the classification, regarding therequirements on the dam owner and surveillanceauthorities concerning dam safety is considered andreviewed. The thesis is pointing out similarities anddifferences in the line of dam safety.The survey of dam safety is firstly based upon legalrequirements in the different countries andsecondly on guidelines regarding dam safety. Damowners generally are ultimately responsible for thesafety of their dam, and often have their ownroutines regarding how this safety is to be achieved.In this thesis, however, the legal requirements aremainly focused upon.The investigation has resulted in an outlining ofeight areas, where the classification systems in thevarious countries have been compared.

Quality Control is a term often used within production and is referring to managing processes so they produce capable products. Within Quality Control, process capability index is a common measure to oversee processes. Safety Region Plots were introduced to do this graphically. In Albing & Vännman (2010) the concept of Safety Region Plots is expanded to incorporate an elliptical shape. The method of Elliptical Safety Region Plots assumes a normally distributed data.

Forest as an investment alternative has become more and more popular over the last few years. Between the years 2004 and 2007 increased the price level on forest land with 70 percent in Jämtland. In this thesis a comparison has been conducted between forest in Jämtland and an investment in the stock market. The risk in the two investment alternatives has been included in the comparison. The thesis includes two different studies between the two alternatives.

Energy costs are high nowadays and that is the reason why the energy consumption needs to become as small as possible in most of the companies. To accomplish the small energy usage one needs to map the energy flows, study them and monitor them. One method that can be used for this is energy balance calculation. The method gives an opportunity to separate different energy flows and see where each flow is heading. There is also another method which is more advanced than energy balance calculation.

The purpose with this work is to investigate the cost to produce piglet in a case study company. The starting point is going to be the agriwise (www.agriwise.org) calculation which I am going to change and adapt to the case study company. To day the pig market is bad but we have probably reached the bottom. The market has started to rise. It is no business to produce piglets today.

AbstractThe Swedish school is the biggest place of work in the country. Statistics about the Swedish school shows that both students and teachers work in an environment who has elements of violations, threats and violence, and study environments where many students do not feel they have a study environment during class. The purpose with this study has been to investigate if teachers and principals is given the right conditions in their respective educations to pursue their professional profession to achieve the objectives of the goals with the systematic safety and work environment of the school's safety concerns. The study has been designed as an investigation about respective educations syllabus and has been examined by the presence about systematic safety and knowledge about work environment law in respective courses. The examination about respective educations syllabus has been done by a qualitative content analysis.

The aim of this paper is to examine the psychosocial work environment and safety culture in minor Swedish airports. The purpose is also to investigate the relationships between these two. The paper deals with theories regarding psychosocial work environment, organizational culture and safety as well as safety culture and safety climate. The participants are air traffic controllers working in minor airports in Sweden. The psychosocial work environment was measured with Copenhagen psychosocial questionnaire (COPSOQ) and the safety culture with the safety culture assessment questionnaire (SCAQ).

The implementation of IFRS 2 led to significant changes in the accounting practices for corporations regarding stock related compensation. The new regulations required firms to account for the stock based compensation as an expense in the financial statements, rather than merely disclosing the information in the notes section to the statements. Following prior research on the area; specifically studies made in the U.S., where researchers find that companies change their use of stock based compensation due to the increased accounted expenses, this study hypothesizes that the same pattern may be found among companies listed on the Swedish stock market. The results of this study show that the use of option incentives has decreased during the studied period 2001-2008 and that the decrease in part can be derived from IFRS 2 and in part from other factors. The results are useful to future research, as they provide an overview of the effects that IFRS 2 had on companies, and various factors that influence the behavior of corporations, as well as in a larger perspective be a factor to take into account for future modifications of the IFRS..

The purpose of the present study has been to investigate the attitudes of personell involved in the preschoolorganisation in a Swedish commune regarding injury risks for children in pre-school. Sixrespondents were interviewed in a qualitative interview study.Two different pre-school units were investigated, and it was found that they had surprisingly largedifferences in how they were working with children safety. However, in summary it can be said that therespondents perceived that child safety should encompass a safe and secure environment, however withthe important caveat that accidents can never be completely excluded, due to the natural anddevelopmentally important play of children.The investigated commune and pre-school units improved children safety mainly by using yearlyplanning meetings (Sw. "barnskyddsrond") where the physical environment in the school wasinvestigated together with external specialists. However, there are important differences in how the unitsworked within this framework, some units actively encouraging and others discouraging children andparent participation in the work..

Business unit Cylinder at ASSA AB in Eskilstuna are having problem with frictions in their production process. Changes are occurring and older products along with machineries are phased out and transferred to low-cost countries. This opens up possibilities to at a larger extend customize physical flows after production flows. The authors where given the task to analyze the production and find problem areas to improve and to give suggestion on how Business unit Cylinder can work to optimize their production flow.The aim of the thesis work is to come up with suggestions on how to reduce the lead time in production and how the tied up capital can be reduced. In more detail the task included to find problem areas that are counteracting an effective flow, give solutions on new flows for the production of the cylinder core, give suggestions for new stock points for the production and how the production shall be managed and controlled.During the last twelve months ASSA AB has sold over 700 different types of cylinder cores, and the product range is very wide.

This report is about the shear force design of reinforced concrete according to Europe?s common dimension rules, Eurocode. The purpose is to describe the calculation procedure and the background to the formulas and expressions that occurs. Furthermore results from different calculation methods (hand calculations and computer calculations) will be compared to see how they differ.The goal with this is to go through the parts of Eurocode dealing with shear force and that this will lead to a clear review of these. You should also be able to see how results and the calculation procedure differ between different calculation methods.

This study is based on an ongoing debate regarding the Stockholm Stock Exchange, which centers around the possible abolition of quarterly reports. The purpose of this paper is to contribute to this debate by examining how the relationship between financial reports and stock price correlates. The study's methodological approach is based on the Capital Market Research frame-work in which an ERC model and an extended model are used to measure the relationship. Three hypotheses were formed to categorize the direction of the study, these categorizations treats the differences in impact between quarterly and annual reports on stock price, as well as differences in impact as a casual effect of company size and seasonal sensitivity. The results of the study show that quarterly reports have a stronger impact on the share price than annual reports.
