Simulation driven design : An iterative approach for mechanical engineerswith focus on mesh, quality and convergence

This thesis of 15 hp has been implemented at Halmstad University, incollaboration with Saab Dynamics in Linköping. Saab Dynamics is a companyoperating in the defence industry where competition is tough. This necessitatesnew ways to increase efficiency in the company, which is the basis for this thesis.Saab Dynamics wants to introduce simulation driven design. Since SaabDynamics engineers have little experience of simulation, required a usermethodology with clear guidelines. Due to lack of time, they chose to assign thetask to students, which resulted in this thesis.The aim of the thesis is to develop a methodology in mechanical design, wherethe designer uses the FE analysis early in the design process to develop thestructures' mechanical properties.

Metod för att bestämma drifttid

The usage time is an important part of the specification for products powered bybatteries. The usage time is affected by a number of different elements; technical,environmental and how the product is being used. The method to determine theusage time is intended to define how measurements and calculations are to berealized along with influencing factors to keep in mind. With support from thismethod the intention is to gain control on how well the established usage time canbe expected to cohere with the real value and what affects the value.The study is done specifically for hearing protectors with battery powered built inelectronically functions. The functions can be level dependent function forambient hearing, 2-way radio communication, Bluetooth or FM-radio.The first chapter of the report describes the literature study performed in theproject.

Dockor, bilar och rutschkanor : Leksakers genusbetydelse i bilderböcker

This essay will focus on the significance of gender in toys´ portrayed in children books for the age 3-5years. The aim for the essay, partly, is to highlight how gender stereotypes can come forth and affect children through the way toys are illustrated within children?s books. The essay will address books from two different time periods, the first period being the 40-50- 60's and the other being the 00´s. The questions to be addressed in this essay is; what type of toys? children play with in the books used in the analysis, and if a change can be detected between the different time periods in terms of gender awareness in what type of toys are presented in the books.The main method used in this essay is an iconological image analysis in which the first step is mapping, other methods used is analysis and interpretation.

Handelshinder som policy. Exportkontrollens effektivitet och påverkan på Sveriges handel med krigsmateriel 1984-2010 kopplat till policyutveckling.

The purpose of this thesis is to analyze the regulatory power, efficiency and impact of export control on Swedish arms export from the 1980s onwards, linked to the delegation of authority of permit license to the Inspectorate of Strategic Products in 1997. An increase in the administrative sector, based on a collective decision making process and established criteria and guidelines, aimed to strengthen the control of arms export to non-democratic and problematic states. In short, the aim of the study is to investigate and analyze whether there was a decrease in the arms export to problematic states or not. On one hand, it is reasonable to assume that the introduction of the new regulation entailed a more strict arms export policy. However, previous research has showed that regulations are sometimes not effective since incentives to breach these may be present.The study begins by examining the Swedish case and situation in terms of arms manufacturing and export, as well as the delegation of authority and legislation applied to the field over time.

Blödningsbenägenhet hos bengalkatter :

During the years 2005-2007 several cases of abnormal bleeding were seen after surgery in Bengal cats on veterinary clinics and animal hospitals in Sweden. In this study we have examined if the observed bleedings are due to an inherited defect of the coagulation cascade. Ten Bengal cats were tested for activated partial thromboplastin time (P-APT-time) and one-stage protrombin time (P-PK), and nine of these cats were tested for fibrinogen quantity (P-fibrinogen). Four of the tested cats had shown signs of an abnormal bleeding after surgery, and five of the cats were genetically related to these cats. One cat had a small bleeding wound at the internal base of the right auricle.

Quantification of sleep in dairy cows in three different stages of lactation

The aim of this project was to quantify the total sleep time in modern dairy cows during24-hour periods and to investigate whether the total amount of sleep as well as timespent in different sleep stages varies between the dry period, early- and peak lactation.The distribution of sleep time between night and day was also examined. Furthermore,correlations between sleep and lying time, fluctuations in body temperature and heartbeat were included in the aim. Eight dairy cows of the Swedish Red breed were used inthis study, which was carried out between June and September 2010. In order toquantify sleep non-invasive electrophysiological recordings were performed.Simultaneously with collecting sleep data, body position and body temperature werealso recorded. No heart rate data was obtained due to difficulties of maintainingelectrodes for heart beat measurements attached to the skin.

Deltidsarbetandes företrädesrätt till högre sysselsättningsgrad

During the 20th century Sweden faced an increased proportion of workers registered as part-time unemployed, especially in the care sector. However, due to many valuable efforts, aimed at solving the problem of part time unemployment and political decisions, the number of people who are part-time unemployed has declined since the late 20th century. We have investigated part-time workers preferential right to extending their working hours. According to Section 25 a of the Employment Protection Act, part-time employees who have submitted an interest in increasing their working hours has a preferential right to increased working hours, with the assumptions that full-time employment with the employer will meet a labor need that the employee has sufficient qualifications for.Qualitative interviews have given us information about how Karlstad Community and a private care company deal with part-time unemployment and their workers preferential right to extending their working hours. We have found that people who work for Karlstad Community have an opportunity to choose their number of workings hours, thanks to a political decision made in Karlstad Community, aimed at solving the part time unemployment in the care sector.
