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..

The workplace is perhaps the most developed arena for prevention of diseases and injuries among employees. In addition, according to the Swedish Work Environment Act, the employer is responsible to address physical and psychosocial risk factors. Moreover, many employers use health promotion, primarily related to individuals and their ambition to maintain or improve health, for example through dietary means and exercise. The aim of this study is to investigate health inspirers in municipal activities and their perceived support and motivation in work related to health promotion at the workplace. A qualitative method was chosen where six health inspirers within Ludvika kommun were interviewed.

E-commerce is becoming more common in Sweden and many Swedes buy clothing and sporting goods online. Online fashion retailers offer a visually pleasing range of products, which places greater emphasis on the aesthetic design of the online retailer. This paper examines how the perceived credibility of an online fashion retailer is influenced by the aesthetic design through a first impression. This study was conducted through ten interviews where the informants observed, assessed, and then discussed the online fashion retailers that were used in this study. Results show that recognition of an aesthetic design and a perception of usability and professionalism affects the perceived credibility in a positive way.

AbstractWe´re surrounded by music in many different ways. Sometimes we choose the music ourselves and sometimes it?s just there. The purpose of my thesis is to illustrate the students apprehension and understanding of the teaching of music in school. Moreover, my own interest in this subject and its influence during my school years motivated me in researching my thesis.

Three main questions give the fundamental structure for this master thesis: 1) In what way is the notion of law being perceived in the following theologians respectively; David P. Scaer, Dietrich Bonhoeffer and Wolfhart Pannenberg? 2) In what way is the notion of law being perceived in the encyclical Veritatis Splendor? 3) Which similarities and divergences can be found in the respective expositions of the notion of law?For the purpose of comparison, I have employed four questions of analysis. These are: A) What is ?the law?? B) Is the law being effected, or is it working, in the world and if so - in what ways and for what purposes is it meant to serve? C) Does human beings have any capacities to understand and/or live in accordance to the law? D) Does the Gospel, perceived as the earthly life, actions, death and resurrection of Jesus Christ, effect any alteration with respect to the purpose, range, function or interpretation of the law?In order to better understand Roman-Catholic concepts of law, the treatise on law of Thomas Aquinas Summa Theologica is briefly presented.

The aim of this literature review was to investigate whether the modern dairy cow has the time she needs to lie down and to sleep and what deprivation of these behaviors could lead to. Current research seems to agree on the fact that sleep is essential but there is no uniform explanation of the function of sleep, even though there are many theories. It is known that sleep has an important impact on the immune system and that sleep is increased in case of an infection. Sleep deprivation causes many negative effects including reduced function off the immune defense, increased metabolic activity, malnutrition and increased heart rate. It has also been found that deprivation of sleep could cause increased mortality.

While the call for regulations against greenhouse gas emissions are louder then ever before, demand for oil is also at an all time high. Oil companies face the dilemma of making sound business without being perceived as environmental villains. In this essay I will examine how BP, one of the largest companies in the world, broke rank with the industry and devoted itself to being an environmental friendly oil company. The actions and motives of this change will be evaluated through up-to-date theories about company motivation to environmental adaptation. We see that BP:s transformation can be well explained through Simone Pulvers theory about the socially embedded company.

Popular culture is a phenomenon of growing importance in the society today. Children and teenagers are increasingly using popular culture in their everyday life to reflect and answer questions about their identities and the meaning of life. Swedish primary and upper secondary schools are expected to prepare their students for adulthood and to provide them with tools to explain understand and problematize contemporary society. From this perspective it is relevant to question whether the schools achieve this and whether the instruction given there represents the contemporary society. For the purpose of knowing more about how popular culture is perceived and dealt with in the Swedish education system, this study examines how eight textbooks in Religious Education (RE) and the national curriculum for upper secondary school discuss and treat popular culture.  The study focuses on when and in what ways the textbooks mention popular culture and if the curriculum provides any supportive base for including popular culture in religious education.

The aim of this thesis is to investigate the content in Swedish library weblogs. We want to examine what the posts contain, especially on the subject knowledge organization. Which themes do the weblogs have in common? How the weblog authors categorize their posts and how the readers use the comment function, are other questions we seek answers to in the thesis. We have performed content analysis where we created the code units during the process.

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

This essay is reading the Swedish author Stig Larssons debut Autisterna [The Autists] (1979) in the light of Gérard Genettes narratology and the time philosophy of Gilles Deleuze. The focus of the essay is time and how it is seemingly dissolved. The essay maps out a chronology of the non-chronological novel and from there discusses the breaking up of the empirical time. The essay uses Deleuze to explore the time-image of the novel to see how it is built up in the text for example by literary anyspace-whatevers. Hence the title, Anytime-whatever.

Efficiency has become an important objective for many providers of welfare services. Among Swedish schools, both private and public, increased administrative demands seemingly influence operations, and affect teachers negatively through perceived stress. Simultaneously, Swedish students scored an all-time low in the latest PISA survey, and are now performing below the OECD-average in science, mathematics and reading. A central administrative task in the Swedish elementary school is the parent-teacher conference, which is an important activity in supporting the development of the student's knowledge and social skills. Lean is a well-established operations framework, which has proven successful in order to improve process efficiency.

The basis for this study was my own conception of a weakening of recreational activities in the Swedish secondary school. The aim of the study was to look into five school leaders? ideas of recreational activities. The school leaders? who participated came from various municipalities in two different counties, southern Värmland and northern Västra Götaland (former Skaraborg).
