To be able to Measure high-surge voltages and transients with short rise times youneed measuring instruments with a high sampling frequency and large Bandwidth.These surges and transients occur primarily at lightning but can also occur at forexample at connecting errors at an electrical switch-gear. This report describes thework with finding two solutions for measuring and log data from these surges andtransients. One temporary solution where a Measurement program has beendeveloped. A second solution where different company solutions have been analyzedto decide which fits best. For these Measurement solutions two solutions for bringingdown the voltage has been used.

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to Measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

Each year, Heterobasidion spp. is a major cause of economic losses to forestry in the northernhemisphere, including Sweden. New results indicate that pre?commercial thinnings could be at riskfor Heterobasidion spp. infections.

Corporate Social Responsibility (CSR) is about facing responsibilities towards a company?s employees, customers, stakeholders, suppliers and the environment. As customers and consumers came to seek companies that were dealing with CSR a rapid wave of ?forced? implementations of social responsibility began. Fair Travel Tanzania, which has CSR as the foundation of the company, says that they are transparent about what they do and how they give back to the locals, could it be a problem with this? And how do they actually give back to the locals? Is it possible to Measure the impact of CSR activities within the company? And if so, how?.

Plagionotus detritus is a threatend longhorn beetle that only exists at one site in Sweden. It is saproxylic and depending on recently dead coarse oak wood for its larval development. Trees at Djurgården, Stockholm that have been colonized by Plagionotus detritus has been studied to find out the habitat preferences of the species and to see what affects the density of beetles in a tree. The bark of some trees and wood from the breeding project at Nordens Ark has also been studied to find out what affects the species reproductive success. The reproductive success was Measured in two ways, the larval mortality and the size of the hatching holes.

Horses respond individually to challenges, and the possibility to use these reactions to evaluate equine temperament with an objective instrument would have several advantages. Horse welfare could be improved by making it possible to find individuals best suited for a specific use, and understanding of the development of abnormal behaviours, such as stereotypies, could be increased. Management routines and training could be adjusted tosuit each individual horse and it could facilitate the selection of individuals appropriate for breeding. There are also economic implications, as horse buyers consider temperament important and after evaluating temperament, money can be spent solely on specific horses with all the right qualities. During the last decade, many attempts have been made to Measure different aspects of temperament in horses, and the first aim of this project was to look at these studies and see which methods were used and which temperamental characteristics they Measured.

Driving simulators are a very important part of the research that is done at VTI. Enhancing the realism and creating a better driving experience in the simulators are very important and an ongoing work process for the engineers and researchers who work with the simulators. This project has been done as a part of this developing process and the purpose is to enhance the realism of the rear-view mirrors.Simulating realistic rear-view mirrors has been demanded, not only from the researchers at VTI, but also from car and truck manufacturers. To achieve a realistic mirror view a method to Measure and parameterize real mirrors has been developed. The code for the existing graphics system has also been redone to be able to handle the new types of mirrors introduced..

The political landscape is constantly changing and influenced by outside forces. The strong connection to the traditional media has evolved to include a new important part, social media. A good way for the politics to utilize social media is through their youth associations, whose main purpose is to engage young people and spark their interest in politics. Due to the increasing influence of social media, the politicians, parties and various actors have to adapt to its demands, to be able to gain visibility on these platforms. One way to adapt is to become more entertainment driven, because these platforms are a safespace where people find time to relax and have a good time. With a growing emphasis on simplified, engaging and more fun political massages, political communication has changed its form. This phenomenon is referred to as ?politainment? and encapsulates the merging of politics and entertainment. The purpose of this study is to examine and Measure the frequency of politainment in Swedish political youth associations political communications.

This master thesis deals with problems in the arc length control in Pulsed MIG/MAG Welding. The main problem is that it is not possible to Measure the arc length. In the present solution the voltage over both the electrode and the arc represents the arc length. To improve the arc length control a model of the electrode melting has been built. One output from the model is the voltage over the electrode and with this voltage together with the Measured voltage it is possible to calculate the voltage over just the arc.

There are two objectives of this study.The first one was to study the new instrument Deltack fromPrufbau, and with the new knowledge, study the interaction between blanket and paper.Deltack is a new instrument to Measure the ink splitting force. Blankets from an earlier study doneby GATF have been montered on 12 different Deltack print forms and those have together with Deltackbeen the base for this project.This study together with information from GATF?s study shows that some of the blankets have ahigher capability to adsorb ink. Those blankets generate a sharper shape on the force curve, they havea lower dot gain, but they print not as good solid..

Små och medelstora organisationer finner sig ofta vara aktörer på en mycket konkurrensutsatt marknad där det är avgörande att uppnå ständiga förbättringar för att förbli konkurrenskraftig. Six Sigma (även känt som Sex Sigma) är en mycket populär metod för processförbättring, med hög framgångsgrad, hos stora organisationer. Denna uppsats och examensarbete försöker utvärdera huruvida små och medelstora organisationer kan anamma Six Sigma. I strävan att utvärdera detta utfördes ett Six Sigma processförbättringsprojekt vid Ecolean AB i Helsingborg, Sverige. Fynden i denna studie antyder att Six Sigma kan anammas av små och medelstora organisationer.

This study examines if the prediction of cardiovascular disease in hypertensive patients can be improved upon when renal function and microalbuminuria are added to the classical risk factors The predictive capability of a model is Measured by discrimination, calibration, reclassification and Harrell's C.The results are ambigious. In most cases, microalbuminuria should be included in the model, but the results regarding the other Measures of renal function are varied. Therefore, the selection of risk factors to include in the model depends on which Measure of prediction one prioritizes..

A comparative thesis to study precious metals impact on a portfolio, during a long period of time, from the fourth quarter of 1986 to the third quarter of 2012. Five different portfolios are compared; three of the portfolios containing one of the following precious metals, gold, silver and platinum, the fourth portfolio contain all precious metals and shares, and the fifth portfolio containing only shares which is represented of OMXS30. This is done to determine the portfolio that generates the most return in relation to the least risk with the help of historical prices. Sharpe ratio is used to Measure the profitability of precious metals by measuring the yield relative to the total risk. The study also Measures precious metals correlation with shares..

The aim with this study is to see how social workers apprehend the law, support and service for persons with certain functional impairments (LSS) and the application. We interviewed six social workers in six different municipalities to get a distribution between small and big municipalities. In the study we have used a qualitative method with half structured interview questions, since we wanted to get a comprehension for the social workers apprehensions. We have used a communication theory and a role theory in the study. The result showed that the social workers consider that the LSS is important, but that there are a few difficulties in the application.
