With the advance in computer and network technologies, multimedia systems and Internet applications are becoming more popular. As broadband network is prevailing, more clients are able to watch streaming videos or to play multimedia data over the Internet in real-time. Consequently, there is an increasing demand in the Internet for streaming video systems. As the run-time environment of such applications tends to be dynamic, it is imperative to handle transient overloads effectively. The goal of this work is to develop an algorithm that would provide a robust and controlled behavior of the video system so that important data is delivered on time to the video clients.

The purpose of this paper is to compare two different portfolio strategies consisting of insider transactions and stock recommendations and examine whether they posses any information advantage.  The portfolios are balanced once every three-, six- and twelve- months in the period of 2007-2009. Our results show a pattern for these investment strategies. The portfolio consisting of insider transactions generates a positive return in equity in a negative market environment and the opposite reaction in a positive environment. The result for the portfolio consisting of stock recommendations show a positive return of equity in positive environment and the opposite effect in negative environment. The pattern that has been observed can be classified as an anomaly.

Arbetsmiljöverket har under 2008 och 2009 gjort inspektioner hos Hudiksvalls kommun. Arbetsmiljöverket konstaterade i samband med dessa inspektioner att chefer och arbetsledare saknade kunskaper om arbetsmiljölagen och dess föreskrifter. En utbildningsplan inom kommunen var lagd under 2009 för att rätta till dessa brister. Hudiksvalls kommun har en önskan att veta om utbildningen i det systematiska arbetsmiljöarbetet gav förbättrade kunskaper inom området. För att ta reda på om utbildningen gav förbättrade kunskaper har en undersökning gjorts mellan två grupper, varav den ena inte har gått arbetsmiljöutbildningen.

AbstractThe Swedish society has always been monolingual, but has for the past decades transformed into a multicultural and multilingual society. The aim of this study is to investigate if and in that case how preschool teachers work with language development in bilingual and multicultural preschools. The concept of linguistic and cultural diversity includes several different components, not least the social interactions that are of great importance to every individual's development, learning and participation in the world. By understanding the importance of language, language development and the role of mother tongue in second language acquisition, we look into various researches done concerning the effects of the preschool teachers? opinions, methods used to language developmental primarily for children who are multilingual and how the physical environment is shaped to promote language in multicultural and multilingual preschools.The method used in this study is semi-structured interviews with preschool teacher working in multicultural or bilingual preschool settings.

The purpose of this study is to gain knowledge and a broader understanding for how pre-school teachers describe the importance of planned play environments including in what manner children are given influence. By qualitative interviews with five pre-school teachers from four different units I was able to gather data that shows how the planning process concerning a specific play environment had worked and why it looked as it did. The results show among other things that the pre-school teachers viewed the play environment as a vital part of the daily operation and pointed out that it was of vital importance that it came from the children?s interests. Depending on how the play environment had been organized and what its purpose was it offered different amounts of affordances..

To challenge the competition within the construction business there are requirements ineffectiveness and use of operating computer based programs and work-methods. Thecomputer based programs are continuously improved and can at some point be the start of anew work-method. The work-method of tomorrow can be Building Information Modeling(BIM).This Master of Science Thesis gives an understanding in what BIM is and what therequirements for Sweco Theorells are in a future BIM-use as a consulting-firm. Theunderstanding is presented through a study of theory within the subject. The way of thinkingand acting among different disciplines and individuals within the building process isexplained through an interview study.The term BIM is regularly used.

I have written an experiential essay about my role as a preschool director and the important work decisions that I face. What is best for the child? That is something that I think is important to take into consideration.In the narrative, I describe how an induction occurs at my preschool. We use an "old" tried and true method which spans two to three weeks, which I believe is best for children under the age of two. They need to first connect withone educator who they are comfortable with before they are secure enough to play and explore the environment of the preschool.In recent years, another method has emerged which is shorter and which has quickly became popular in many preschools.

It is said that libraries are the cornerstones of democracy.What is then the democratic mandate, and how is itperceived by the library staff? That's what I examine in thismaster's thesis. I?ve made 14 phone interviews with librarystaff, from assistants to managers, and examined what theirdaily work routine looks like and what they think belongs tothe democratic mandate. I found that all agree that there is ademocratic mandate, but it is not clearly stated in anydocument.I found seven areas that my respondents saw as part of themandate; availability, diversity, children and young people,equality, public education, free of law and cultural history.These are not sharply defined, but can often move into oneanother.

Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig.

I dagens samhälle kan vi se en allt starkare trend i riktning mot internationalisering och globalisering. Genom att det har blivit lättare att förflytta sig över nationsgränserna har detta öppnat dörrar för såväl privatpersoner som företag. I och med detta har många företag och organisationer fått anpassa sig till, lära sig att förstå och hantera kulturell mångfald. I globala företag är det inte ovanligt att man som manager eller ledare arbetar tillsammans med eller leder anställda med annan nationell kulturell bakgrund än sin egen. Detta kan ibland leda till missförstånd och merjobb, men bidrar även till dynamik och inspiration på arbetsplatsen.Vi genomförde en kvalitativ undersökning som grundade sig på tre djupgående intervjuer med managers på olika nivåer på ett multinationellt callcenter i Wien.

The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.

During the nineties, ecological handling of urban storm water became very popular in Sweden. Together with Chalmers University of Technology and two Swedish communities, DHI Water and Environment has been doing research of storm water ponds and constructed wetlands. This thesis work is a part of that research project. The work has been applied at the Bäckaslöv storm water treatment plant in Växjö, Sweden. The plant consists of one storm water pond and a downstream constructed wetland.

Today?s society has become more and more digitalized and we have access to more information than ever before. This has had a major impact on organizations and their work processes. For example have intranets become a common technical groupware to communicate and get relevant information from inside the organization. A common problem related to this is an over-reliance on the technology, where there's not taking into account that some informal and communicative means are difficult to occur through digital resources.The aim of this study is to examine the use of an intranet in a municipality, which consists of many different employees with various work situations.

Arbetets struktur kan påverka individens hälsa i både positiv och negativ bemärkelse. Syftet med denna studie var att undersöka den psykosociala arbetsmiljön på Ängdala Skolor. En kvantitativ metod har använts där 50 ut av 55 anställda som under våren 2009 arbetade på Ängdala Skolor har besvarat en validerad enkät. Resultatet analyserades utifrån Karaseks och Theorells krav-kontroll- stöd modell som teoretisk referensram tillsammans med teorier kring socialt stöd och stress på arbetsplatsen. Då populationen var liten har resultatet även till viss del jämförts med en tidigare studie inom samma område, utförd av Region Skåne.

In Sweden, exercise takes a great part in people?s lives. Health and a good conditioned body go hand in hand. Many Swedes exercise in groups, with aerobics or a similar form of workout at a training facility. A regular workout lasts for about an hour and is accompanied by music.
