This thesis is the result of the class Examensarbete, 15 credits of the mechanical engineering program at Halmstad University. The class represents the final part of the program with the aim to attain a Bachelor of Science. It´s a project made during the spring 2014 in collaboration with Alutrade AB and ScanBox Thermo Products AB.The assignment is to develop a new transportation trolley for ScanBox. The aim is to complement their range with a product that opens up to new markets. That set new demands for materials and also manufacturing- and assembly methods.

Randomness is a complex area of computer science, where only pseudo random numbers are possible to generate algorithmically.This report presents established algorithms for random number generation by conducting a basic study of relevant literature, while testing distribution and speed of the algorithms contained within the C++11 Random library. The results are compared to the algorithm XORShift and a modified version of it. The study shows that the modified algorithm passes all tests in Small Crush, andthat the run time is shorter than for those in the Random library. The conclusion is that it is possible to, with simple means, modify an algorithm to outperform the algorithms of the C++11 Random library..

The current paper compares the relations between different measures of activity and some common neuropsychological tests. One-hundred and fifty five healthy elderly, aged 55 - 85, living in Sweden were included. Gender-specific patterns were found for both activities and correlations between activities and cognitive measures. The main findings suggest that activities are associated with cognitive speed in men, whereas, for women, active and passive activities correlate, positively and negatively accordingly, with education. In comparison, complex models of activity outperform simpler ones and theory-driven measures just barely outperform intuitive models..

Syftet med studien var att undersöka vad som påverkar valet av fritidsaktiviteter hos personer som haft stroke och på vilket sätt fritidsaktiviteterna har förändrats. För att uppnå syftet valdes kvalitativa intervjuer som metod. Intervjuerna var semistrukturerade och utgick från en egengjord intervjuguide. Resultatet visade att utmaningen, gemenskapen, fysisk träning, självständighet, balans i vardagen, livssynen och rehabiliteringsteamet var faktorer som påverkade deltagarnas utförande av fritidsaktiviteter. Att anpassa fritidsaktiviteten eller att få personligt stöd var vanligare än att anpassa den fysiska miljön..

In this paper the rate of convergence, speed of execution and symplectic properties of the time-integrators Leap-Frog (LF2), fourth order Runge-Kutta(RK4) and Crank-Nicholson (CN2) have been studied. This was done by solving the one-dimensional model for a particle in a box (Dirichlet-conditions). The results show that RK4 is the fastest in achieving higher tolerances, while CN2 is the fastest in achieving lower tolerances. Fourth order corrections of LF (LF4)and CN (CN4) were also studied, though these showed no improvements overLF2 and CN2. All methods were shown to exhibit symplectic behavior..

One of the distinguishing features of successful societies is the ability to adapt to change, bothsocial but also natural changes like climate change. Climate change is a complex, dynamic,non-linear process with a great deal of uncertainty concerning the time perspective, risks andconsequences. A combination of factors like climate change, geographical vulnerability, adensely populated and highly built up coast line along with factors like deficient handling ofsurface runoff and a large usage of ground water leads to an increasingly vulnerable society. Italso puts a greater pressure on the society to have preventive measures in place.The number of actors working with preparing society to the expected impacts of climatechange and variability is increasing. However more than half of Sweden?s municipalities donot consider changing climatic conditions when planning, and many times even allow theconstruction of new living areas in known climatically vulnerable areas.

Husums plant has a selection of different pulp pumps at bleaching plant 4 and 5. The displacement- (HC-pump, Sund Defibrator PTD-60) and centrifugalpumps (MC-pump, MCA 42-200, MCP 30/20) are of interest in this report. The centrifugal pumps are controlled by throttle valves, which result in an energy loss. Chemical mixers are used to mix ClO2 into the pulp before proceeding into a holding tower where the bleaching process occurs.The energy demand of the different positions has been measured or calculated to be used in comparisons against new equipment. Quotations were requested and delivered from Valmet and Sulzer.

During the spring of 2013 we developed a visual identity for Jönköping Bandy, a bandy association in Jönköping, which was founded in 1947.Jönköping Bandy?s main problem was the low interest for the association by the local people. The association also had problems with the economy, which made it hard for them to merchandise themselves.In Jönköping, there were a lot of sport associations, and therefore, it was difficult to find sponsors. One way to help the association, was to create a good visual identity for them. A visual identity that would reflect on the proper values of the association.The intention was: ?Through graphical design, we want to convey Jönköping Bandy to a larger amount of people, and get increased knowledge in graphical idiom.? and was torn apart into these three questions:What core values does Jönköping Bandy have, and how can we convey them through the visual identity?Which visual materials does Jönköping Bandy need?How do other teams in Allsvenskan Södra merchandise themselves through their websites?The work began with a study of relevant theoretical literature, with focus on graphical design.

Det här arbetet är en utvärdering om huruvida det finns problem som kan få en prestandavinst då man använder en Field-Programmable Gate Array (FPGA) som hjälpprocessor till en mikroprocessor i jämförelse men att enbart använda en mikro-processor. För att avgöra detta implementerades algoritmen gaussfiltrering dels på en mikroprocessor med språket C och dels för en FPGA med hårdvarubeskrivningsspråket Very-High-Speed Integrated Circuits Hardware Description Language (VHDL). Simuleringar gjordes för dessa två implementationer och resultatet visade att det var möjligt att få en prestandaökning på 25 gånger för denna speciella algoritm..

This study is a study of the assessment and grading of Swedish students with physical disabilities in physical education. The purpose of the study has been to look into how teachers assess and grade students with physical disabilities, and if there are any difficulties or problems in this assessment and grading. Focus has been on students in year three to six because this is where the assessments and grading take place. It?s a qualitative study, where eight teachers have been interviewed using a semi-structured interview model.

The purpose of this study is to compare social media's role in the proactive crisis communication planning in two administrations, two companies and two non-profit organizations. A qualitative comparative study method has been used and people familiar with social media and crisis communications work from each business has been interviewed. The interviews have been transcribed and analyzed to discover the opinions and reasoning about how businesses work with proactive crisis communication and the role they give social media. The interviews were analyzed based on selected theories and previous research in strategic crisis communications, where issues management and crisis communication plans have a significant role. Also research on the pros and cons of social media and crisis communications channels have been used.

Det finns inte många kvinnliga huvudpersoner inom sf?spel. Undersökningens resultat är tänkt att ge en inblick i vilka egenskaper som föredras vid val av en kvinnlig karaktär för ett sf?spel. Utifrån en genrestudie av science fiction skapades tre egenskapsgrupper: könsneutral, sexualiserad och aktiv.

Handling, loading, transport time and unloading in connection to transport of farm animals affect animal welfare. Induced effects include both psychological and physiological stress responses in animals. The physiological parameters may be measured through blood analysis while behavioural changes often manifest themselves through increased vocalisation, escape attempts and apathy. Physiological parameters are additional parameters of importance when measuring animal stress responses. The handlers behavior during transport has been shown to have major impact on animal welfare and the quality of meat. Animal friendly handling and driving of animals create a more manageable work environment for the handlers. To further increase animal welfare in connection to transport, stables should be built with well adapted drift passage and ramps on the transport vehicle.
