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..

This is a thesis presents a differential gear which is found in a tracked vehicle called BvS10. The tracked vehicle is manufactured by BAE Systems Hägglunds AB in Örnsköldsvik, Sweden. The differential gear has a bolted house. The differential meets the requirement specifications, but the problem is that the bolts are sheared off because of the extreme torque that the differential is exposed to resist.Previous report on the differential show pictures of bolts which have been sheared off at the threads. This report is also includes three lists that explain seven different proposals which some are approved and some are not, and the report also presents the force, tensile, and shear stress.In a bolted connection there is both axial tension stress and radial shear stress, which can lead to wear out and broken bolts.

Education in Swedish sport is mainly based on traditional learning that requires a lot of time and effort, which could be a barrier for trainers since they report a lack of time as a consequence of their commitment as a leader. The Swedish sports movement has noticed some trends that could be seen as influential on the future directions of sport. One of these trends is a changing way of communication where people today communicate to a greater extent with the use of digital technology. The Swedish sports movement has to relate to this and follow the evolution. The use of e-learning has increased in higher education and organizations over the past decades.

2007, Swedish television, ?Uppdrag granskning,? aired their story about ?Louise? from Vetlanda. A drug dependent father had gotten custody of his daughter and sexually abused her from the age of 10 to 15. The local social services got several notifications about Louise suffering of negligence, and did investigate the family several times without taking any actions to protect her. At one time, father and daughter were living in his trailer placed in a gravel pit, and the police worried about her and called social services, because it was below cero degrees outside.

This paper was part of the ongoing cooperation between the Swedish Civil Aviation Authority and the Department of Psychology at Lund University. The purpose of this study was to develop a self-report measure regarding human factors, for the air traffic controllers to fill out before they start their working shift. This in order to aid the team leaders in their judgment regarding the air traffic controller's ability to perform at the right safety level. The self-report measure would also serve as an aid for the air traffic controllers who have a responsibility regarding their own performance. If successful this self-report measure would make it easier for the air traffic controllers to be alert regarding certain factors that can have a large impact on their performance.

Denna studie undersöker och beskriver den psykiska hälsan hos en grupp barn och ungdomar placerade i familjehem i en större stad i södra Sverige. 42 barn och ungdomar i åldrarna 11 till 20 år valdes ut från en kohort bestående av 52 som vid något tillfälle under 2005 befann sig placerade i familjehem. Till barnen administrerades Youth Self Report (YSR), till en av familjehemsföräldrarna Child Behavior Checklist (CBCL) och till barnens lärare Teacher´s Report Form (TRF). Data från barnens socialakter samlades också in. Totala problemskalorna för CBCL och TRF visade att andelen barn på klinisk nivå uppgick till 23 % medan motsvarande siffra för YSR var 9 %.

This report describes how we, with support from SYSteam Datakonsult AB Värnamobuilds a dynamic website for a fictional company. The purpose of this work is to tietogether our studies with the businesses in the region, and expand our knowledge.Together with Peter Bäckrud from SYSteam we worked out the goals to achieve thispurpose. The goals are to create a polished intranet to a company with the webpagepublishing tool EPIserverThis report begins with describing the goals and visions that were set up. Then follows athorough theoretical background that describes the areas we have touched, to give thereader an idea about the work. The report then moves into the creation phase that talksabout the problem that occurred during development.The creation phase is split up into two parts where the first part gives a good descriptionabout how we designed a usability friendly website that would fulfill the goals we had setup.

This report describes the development of an application in collaboration with Designingenjörerna AB. The company has worked for a long time with a community platform and they required an application where users can create their own unique profile representations, called Avatar Creator. An Avatar Creator is computer based application, which makes it possible to create a virtual character. The problem area behind this is that, large websites require a lot of administrative work when people upload profile pictures on different community pages. They can contain abusive material or pictures of other people rather than those who created the profile.The questions in this report are, how can an Avatar Creator help user to get a unique profile of himself? What are the advantages and disadvantages of an Avatar Creator? How to create a user-friendly application?To understand how an Avatar Creator works and get ideas to create an application, exiting Avatar Creators were reviewed on the Web.Collaborative work with Designingenjörerna AB was done to pin down the requirements for the Avatar creator application.

Purpose: The purpose of this study is to explain which factors that affects Swedish listed companies choice of placement for the corporate governance report when the regulation gives different options.Methodology: The chosen research philosophy is positive, research strategy is deductive and methodology is quantitative.Theoretical Perspectives: As support for the dependent (placement) and independent factors agency theory, positive accounting theory, accounting choice, legitimacy-, stakeholder-, and institutional theory are used.                  Empirical foundation:The sample consists of 249 companies. The empirical data consists of the companies Annual reports and Corporate Governance reports for financial year 2011 or when split financial year, 2010/2011. Limitations: A limitation of the study is that it is based on observations from only one year why it is not certain that the results should have been the same if a comparison between several years had been done.Conclusions: The factors size and growth explain the placement of the Corporate Governance Report in Swedish listed companies..

HMS Industrial Networks AB is in need of changing a communications solution that iscurrently based on an ASIC. This will be achieved by moving the communications solution toa FPGA with the help of the programming language VHDL. By doing this, it is possible toreduce the need for specific circuits, get a more flexible platform and thus get a cheapersolution.This report describes a solution for how to move a network protocol from an ASIC to anFPGA. The report shows that the network slave device is working under the guidelines forthis project. This means that it is quite realistic to implement a fieldbus protocol on an FPGA,using VHDL and to maintain the same functionality as the earlier communications solution..

The purpose of this Masters thesis is to investigate the reasons for public libraries to have story-time today and also the reasons for story-time at the public library historically in Sweden. Why is the phenomenon of story-time still existing at public libraries today? The study is based on a questionnaire that was sent to childrens librarians in the Västra Götaland region. The material collected in this questionnaire was put together and resulted in six different categories showing the libraries purposes and thoughts of their story-time activities. The categories were: cultural heritage/tradition, joy of reading, language and imagination, library visits, storytelling and mutual experience.

This paper deals with the problems that can occur during the move of an entire collection.
