This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.

Organisations constantly live under the potential threat of events and accidents that seriously could harm the organisation. Forsmarks Kraftgrupp AB, the company that this master thesis focus on, is in no aspect excepted from this threat. Through an early identification of near misses and the taking of corrective action in use, Forsmarks Kraftgrupp AB has managed to reduce the likelihood and the consequence of events and accidents. The purpose of this master thesis is to evalutate Forsmarks Kraftgrupp AB?s operation experience process on the basis of IAEA?s and WANO?s requirements within the field of operation experience and to develop a usable system applicably within the field of operation experience.The thesis is divided into two parallel tracks, where one is the evaluation of the operation experience process and the other the design of a usable system, applicably within the field of operation experience.

Introduction: The auditor's going-concern warnings express the quality assurance of information and if these are wrongly based, the stakeholders become deluded. Previous research has shown that auditors do not have any major difficulties in identifying companies that are financially distressed to the extent that they risk receiving a going-concern warning. International studies on the determinants of going-concern warnings have instead focused primarily on the auditor's decision regarding companies that are already in bad shape financially. Auditor grounds for issuing a going concern warning may be linked to factors related to the client, the auditor, the audit firm, the relationship between the client and the auditor and the environment. Purpose: The purpose of this study is to find out what specific factors that affect the auditor issuing going concern warnings for financially distressed companies.

The high and seemingly increasing degree of consumer avoidance and disliking of television advertising breaks should raise many questions for commercially financed television networks as it can be argued that benefits sought by both viewers [seeking a fulfilling viewing experience] and advertisers [seeking advertising effectiveness] are eroded by this effect. This thesis studies effects on advertising effectiveness [RecallBRAND; AttitudeBRAND; AttitudeAD] as well as on the viewing experience [SatisfactionPROGRAM/CHANNEL; Attitude PROGRAM/CHANNEL; IntentionPROGRAM/CHANNEL] given a reduced degree of advertising clutter. By conducting an experiment two breaks are compared, one having the standard primetime nonprogram time units (5 min and 30 sec *3?16minutes/hour) and the other the standard nonprogram content cut in half (2.45 min *3 ?8min /hour).Results show that the reduced breaks award advertisers with higher commercial effectiveness. Measures of RecallBRAND demonstrates no differences between the standard and the reduced break, implying a significantly increased likelihood to be recalled and an equivalently lowered risk to be forgotten in the reduced break.

Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.

A large part of the interactions between horse and rider during horseback riding takes place through the reins and the bit and devices for measuring the tension on the reins, rein tension meters, has fairly recently been developed. To safeguard the welfare of the ridden horse riders need to be aware of the rein tension they apply and actively work to decrease it. Furthermore, there is a need to develop the study of rein tension through new techniques and refined analysis procedures. A good-quality rein tension meter should be small in size, sensitive, durable and as accurate for light rein tension as for strong forces. Rein tension meters used in research on horse and rider interaction commonly depend on strain gauge technique for generating rein tension data.

This study was performed to investigate the bacteriological quality of French cheeses made from raw milk. Fifty cheeses of this type were purchased from Swedish retail premises. The methods described by the Nordic Committee on Food Analysis (NMKL) were used to determine the number of Enterobacteriaceae, presumptive Escherichia coli, coagulase positive staphylococci and Listeria monocytogenes. In 32 cheeses (64%) the number of bacteria mentioned above exceeded the determined maximum value. Thirty samples (60%) showed high counts of Enterobacteriaceae.

This report is the product of the course AF101X, a bachelors degree in Samhällsbyggnad atKTH. The task of the course is to design a small house at a given location and also implement adeepening study. The house in this report is located in Kiruna in the north of Sweden, where theclimate is much colder than in the rest of the country.The deepening study of this report is to evaluates how realistic passive housing north of thePolar Circle is based on those facts. The house will to some extent be designed to fit the passivehousing standard.

This thesis approaches the problem of estimating the arm angles of an industrial robot with flexibilities in joints and links. Due to cost-cutting efforts in the industrial robots industry, weaker components and more cost-effective structures have been introduced which in turn has led to problems with flexibilities, nonlinearities and friction. In order to handle these challenging dynamic problems and achieve high accuracy this study introduces state observers to estimate the tool position.The observers use measurements of the motor angles and an accelerometer and the different evaluated observers are based on an Extended Kalman Filter and a deterministic variant. They have been evaluated in experiments on an industrial robot with two degrees of freedom. The experimental verification shows that the state estimates can be highly accurate for medium frequency motions, ranging from 3-30Hz.

This essay sets out to compare political participation in two e-petition systems: The Malmö initiative in Malmö, Sweden, and Better Reykjavik in Reykjavik, Iceland. The main question of the essay concerns the aggregative and deliberative qualities of the Malmö initiative and Better Reykjavik, as well as the relationship between aggregation and deliberation. This main question is divided into four subqueries that lead the empirical analysis. These are: (1) Which similarities and differences in terms of design are there between the Malmö initiative and Better Reykjavik? (2) To what extent have these systems mobilized an aggregative political participation? (3) What similarities and differences are there concerning aspects of deliberation? and (4) What is the correlation between aggregation and deliberation like in the two e-petition systems?The method in use is a comparative cross-sectional study with a 'most similar research design'.

We acknowledge the lack of empirical studies of the performance of analyst target prices in the Swedish stock market by examining the profitability of target prices for stocks publicly traded on the Stockholm Stock Exchange. We use consensus target prices issued between 2006-2010 and create two different strategies to observe the abnormal returns generated during this period. Going long in the top decile stocks with the best target prices and going short in the bottom decile stocks with the worst target prices generates a statistically significant abnormal buy-and-hold return of 8.9%. An active strategy with daily portfolio rebalancing and a timely response to target price changes generates a less significant monthly alpha of 1.4% against CAPM. The results show to be robust against the size effect discovered by Fama and French.
