Hantering av QoS i Distribuerade MPEG-videosystem
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.
CSR i plast- och kemibranschen
Corporate Social Responsibility (CSR) is a topic that is becoming increasingly important in today's society. CSR is a concept whereby companies voluntarily integrate social and Environmental concerns both in their business but also in interaction with their stakeholders. The society of today sets high expectations for how companies take their social responsibilities, especially in industries where the risks to individuals and the Environment are high. In this study, we tried to answer the following questions; what kind of responsibility do companies in the plastics and chemicals industry claim to take and why might this be due? What differences exist between the investigated companies in the industry and what may these differences be rooted in? The purpose of this study was to obtain an understanding of the interest in working on sustainability in the plastics and chemicals industry.
Att köra eller inte köra : En studie av miljömedvetna bilisters dissonansreducerande- och identitetsupprätthållande strategier
Att köra eller inte köra is a qualitative study aiming to show how Environmentally conscious people who utilizes cars deal with their dissonant behavior, but at the sametime maintain an identity as Environmentally conscious. The study is based on the fact that a third of those who drive cars in the municipality of Växjö would like to decrease their use of cars while at the same time having the infrastructural conditions to utilize other means of transportation. The study investigates inner obstacles in the form of habits and lifestyle, but also the different strategies the motorists use to reduce their cognitive dissonance and maintain a green identity. The indicators show that the reason the majority of the motorists continue to utilize cars is part due to inner obstacles (it's adeeply rooted habit, but also a big part of their lifestyles), part due to that the individuals have defenses for their use of their cars, defenses designed to have a dissonance reducing effect. The indicators also show that the motorists value their family higher than the Environment, and in this way they can legitimize many of their car uses.
En känsla av ljud : den subtila och platsanpassade ljudinstallationen som en del av uterummet

Den tredje vägens ufologi : En studie av vetenskapligt gränsdragningsarbete inom Riksorganisationen UFO-Sverige
The following essay or thesis is a study over scientific endeavors in the fringe. It is a study of Riksorganisationen UFO-Sverige, whose proponents aim to make the UFO phenomenon (or phenomena) a subject of scientific scrutiny. To achieve this, the ufologists first have to redefine common concepts of ufology as pseudo science or religion, mainly by challenging definitions given by scientific sceptics on the one hand, and proponents of conspiracy theories or the new age Environment on the other. Thus UFO-Sverige seeks to construct an alternative scientific identity in contrast to adversaries on both sides, each unwilling to give the UFO phenomenon any further examination. Following the work of Tomas Gieryn's sociological grip on questions of epistemology, especially concerning the social boundaries of science from other cultural categories through what has been labelled as epistemic boundary work, during which proponents of a particular field aim to achieve epistemic authority and thus the legitimate right to define what is and what is not science, I seek to analyze how questions of science and legitimacy are actualized in an intellectual Environment or culture not broadly accepted as scientific.
Upplevelsen av hot och våld : En kvalitativ studie med personal som arbetar på barn och ungdomspsykiatrisk akutmottagning
The aim of the study was to examine individual staff experience and management of threats and violence in the acute psychiatric department for children and teenagers in Uppsala. Previous research shows that the experience of threats and/or violence is individual, and that it is difficult to distinguish between these concepts. Research shows that it is particularly vulnerable to work in psychiatry when mental illness is a cause when threats and violence occurs. Threats and violence can result in different consequences for the individual. The study is based on qualitative interviews and the material was collected in the autumn of 2012 at Akademiska sjukhuset.
Matematik : Hur motivera elevens lärande i köksmatematik?
In Adult Education-Restaurant students often have a negative attitude towards the subject of math. Often mathematics is associated with what experiences the students had of this subject in elementary school - experiences that many times reduce the motivation for the same that is so frequent in the catering industry, in different contexts. Mathematics more or less unconsciously permeates restaurant profession at large, and as a chef you must realize the importance of mathematics in your daily work in the kitchen. The purpose of the work is to develop the mathematics lesson weight and volume by planning and designing more stimulating lessons accommodated in the kitchen - combining calculation problems with the work in a real kitchen Environment. The aim is to help increase the students? motivation for and understanding of the importance of mathematics in the kitchen work. An action-oriented research method was used where students in a survey were asked to answer questions about their previous experiences with mathematics and how they themselves thought that motivating lessons on mathematics in cooking should be designed. The survey revealed that the majority of the students thought that the mathematics lessons weight and volume preferably should take place in the kitchen.

Förbättring av U-värde i träkonstruktion för fönster med Aerogel
When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor Environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor Environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..
Geokemin inom osorterade cirklar : Analys av tungmetallers distribution inom jordprofiler tagna från Abiskoområdet, nordvästra Sverige
The Arctic region appears as a pristine remote Environment, yet there is increasing evidence that it is greatly impacted by pollution such as lead (Pb) and mercury (Hg). In this Environment deposition of Hg has increased threefold since the last industrial revolution. In this study five cryosolic soil profiles within non-sorted circles (NSC) in the Abisko region, northwest of Sweden, has been analyzed to improve our understanding regarding how pollutants are distributed within such type of soil. The soil samples have been analyzed with the use of X-ray fluorescence analysis (XRF), for the measurements of the total concentrations of e.g. lead (Pb) and zirconium (Zr).
ISO 14063 : drivkrafter och mervärden för miljökommunikation
The enterprises of today are beginning to realize that Environmental issues are a important part of their activity. Companies and organizations are expected to a greater extent communicate their Environmental work to the world surrounding them in a trustworthy and structured way. Lack of information or information that is incorrect may bring farreaching consequences. Communication is mentioned in several of the ISO 14001-standards. But what is missing is a guideline how companies should act to create and be sure of the quality of the data that can be used in the Environmental communication.
Omvärldsanalys i olika typer av organisationer. En jämförande studie av omvärldsanalysen i en kommun och ett företag.
This master thesis deals with the differences in the design of the Environmental scanning between different kinds of organisations, as well as the demands and regulations etc. in the respective Environments that influence the Environmental scanning. The content of the Environmental scanning and the organisation of the function are outside the scope of this study. Two organisations that do not have an organised function but are scanning their Environment were chosen for the investigation. A model for conducting the Environmental scanning developed by Frankelius is used to analyse the practice of Environmental scanning.
Lärsituationens komplexitet för elever som upplever svårigheter i matematik : Rutiga Familjen i en ny lärmiljö
The Squares Family is a game developed as a learning aid in mathematics. With its graphical representation of the decimal system, the four basic arithmetic operations and positive and negative numbers together with a learning agent as pedagogical approach, the game?s primary purpose is to motivate students in their learning of mathematics. Although the game is strictly based on mathematical rules it attempts to encourage students to play and work with math without experiencing it as mathematics as this is initially not obvious. The game being internationally tested on normal performing students, this project introduced the game to six Swedish students who experience low motivation for and/or difficulties in mathematics.
