OSE och Linux : En studie om prestanda
There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..
Jobba till 75 år?! : Trygghet och egoism i den svenska välfärden med pensionssytemet som exempel
The purpose of this study was to try to understand the Swedish population regarding the perceptions of the Swedish welfare system, based on the reactions that occurred after Sweden's Prime Minister Fredrik Reinfeldt's statement about raising the retirement age. Our results demonstrate that the reactions on changes in the pension system in fact rooted in a safety factor and not the change in the pension system itself, through which the Swedish welfare system acts as a safety net for the population. Further the results shows that these safety factors create a form of egoism. With an interaction between empiricism and theory, where the starting point of the material was of an inductive approach, the material abstracted into different levels from which the result emerged. The focus of this study lies in the understanding of how human beings act according to one's need for security in major changes, which may be of importance to a comprehensive understanding of changes in social structures..

This report details the development of an application for personal safety for the Android operating system. Android is a relatively new platform, primarily used on mobile phones.The purpose of the developed application is to give the user the possibility to easily and quickly alert a number of contacts by phone in case of emergencies, and to show the user?s location on a map. This is not only used during emergencies, but for other purposes as well ? for example to monitor a jogging round.The project was carried out in co-operation with the company D-Safety, the developer of the "SoftAlarm" ? the product on which the developed application is based..
Application of Design for Safer Urban Roads and Junctions: Selected Countermeasures
Road design with focus to safety has been extensively developed in last decades in Nordic and some other EU countries with the main aim to achieve a decrease in a number of accidents and fatalities on the roads. These countries gained many valuable experiences, but they had to sacrifice great effort, expenses, and time to reach the present art-of-state. The purpose of the Master?s Thesis is to review some design approaches with focus to safety and discuss the general way that they may be applied. The Master?s Thesis studies safety in three levels: (i) general - design standards, national safety policies and road hierarchy; (ii) local authority and road administrator; and (iii) three specific safety countermeasures - junctions, pedestrian crossings and traffic calming.
Upprättande av mall för fuktsäkerhetsbeskrivning : Genom granskning av projekt ur fuktsäkerhetssynpunkt
During the 1990?s a large number of building projects were revealed where lack of moistsafety precautions during the construction process had led to extensive moisture damage. Alsoresent implemented studies have shown that the problems with moisture damages have ratherincreased than decreased during the past few years. Moist is considered to be one of the mainfactors to cause unhealth due to deficiencies in the indoor-environment and does also causeunnecessary expenses and a reduction of the confidence in the construction industry.In this Bachelor of Science thesis three projects have been reviewed to examine how moistsafetyhas been observed during the construction process. Main focus has been to identify thebuilding components that are the most exposed to moist, and to examine how they have beentaken into account during the period of design and construction.
Electrolux och patenten. En studie av Electrolux patentstrategiska agerande 1950-1970.
Application Lifecycle Management (ALM) is a genre of computerized systems which allows system development corporations to efficiently and more easily manage, maintain and handle the applications lifecycle. These ALM systems have a wide variety of tools which can be integrated to enable and support collaborative work, while they act at the core of the organisation. Todays ALM systems support flexible system development methods throughout the entire development process. This paper focuses on a case-study of a Swedish business- and technology corporation and their use of two ALM systems with an aim to unravel the differences between these systems and their functionality to serve as a basis for decision making regarding their utilization of best practice with their ALM-Systems. Meanwhile we studied their approach to ALM systems to see if they were using them according to the initial idea of ALM systems.
Trygghet och säkerhet i offentlig stadsmiljö :
To thoroughly think with safety and security in mind is an important issue in planning of public city spaces. Spaces intended to be available to all inhabitants of a city should have a welcoming appearance. Unfortu-nately, this is not the situation in many pedestrian walkways, parks and such spaces, possibly due to lack in safety and security.
This master thesis intend to examine questions at this issue ? what makes you feel safe and what causes insecurity in public city spaces. The safety aspect treats the human psychological and sociological ways of perceiving her milieu and other humans in it, and how the physical shape of her surroundings can affect the sense of safety.
Hästhållningen i Sverige 2009 : intervjuer med 52 hästhållare i 5 kommuner
The purpose of this degree project is to investigate how horse keepers reasons about horse keeping and how the horse keeping looks like today. It is interesting to compare modern horse keeping with ancien recommendations and how the horses were kept then to understand how much in the horse keeping today that is based on traditions instead of research and science. The degree project was based on data from interviews of 52 horse keepers in five different municipalities. All interviews have been based from the same questionaire about how there horses are kept today, what they think about different housing systems, how they think horses will be housed in the future and what problems they think are the biggest in horse keeping today. The results shows that single boxes indoors are the most frequently used housing system today.
Kosttillskott för hundar med artros
The aim of this study was to examine which research had been done on dietary supplements for dogs suffering from osteoarthrosis. The main questions the author wanted answers to were ?Is there evidence in the research that dietary supplements for dogs with osteoarthritis have effect in such a way that quality of life is increased in these animals??, ?are there any contraindications regarding dietary supplements?, ?who is responsible for the control of safety on dietary supplements for dogs in Sweden? and ?what kind of advice would I give to dogowners about dietary supplements?. To be able to answer these questions the author conducted a literature study of the recent research on dietary supplements for OA in dogs. The results showed that despite the lack of research in this field, some promising research has been done on multiple different supplements.
Intensivvårdsventilation i tryckkammare
At this point seamen have a lot of tasks of administrative character, beyond the traditional tasks aboard a ship. Due to the new conventions that are formed by IMO, more requirements are added which often lead to time consuming administrative tasks and documentation that should be spent on activities which are contributing to the ships safety. The issue has been observed by IMO that has through BIMCO done a study with the aim to identify and reduce administrative burdens at sea.The primary aim of this study is to find out if safety officers aboard Swedish ferries consider that SOLAS Chapter III, 8.3 och 19.5 regulations are administrative burdens, restricted to muster lists and documentation of training aboard the ship.The secondary questions to the study are if it is possible to remove, combine or change the documents and how much time can be saved by doing this. The question about timesaving could not be answered, because the values were scattered and could not be used for further investigation. The observed values were accumulated by a survey and the result indicated that safety officers did not experience the two regulations as administrative burdens.

Several cities have implemented various projects to improve traffic safety in city centers.During 1970s and 1980s the city centers changed as the suburbs grew and large shopping centers were located outside the center. At the same time, several projects were initiated with construction of pedestrian streets and restriction of traffic in the center. In year 1994,shared-used areas were introduced in Sweden and these areas are often used in center environments.In Sweden, municipalities are responsible for integrating security in public places and in comprehensive plans and detailed development plans. The National Board of Housing,Building and Planning is the authority for administrating planning issues and develop general guidance about planning. Traffic is one of their key issues, although today there are no concrete guidelines from the National Board of Housing, Building and Planningfor the design of traffic safety in city centers.Traffic safety in city centers affects many people because the city center is a public place.It is therefore important that there are current guidelines available that are helpful for changes and improvements in traffic safety in the city center.The purpose of this report is to formulate guidelines for planning city centers from a traffic safety perspective.
