Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

The purpose of this study was to investigate the relation between SOC, attitudes towards grades, and perceived stress levels among adolescents, and whether there was any difference in this relation between gender. The first research hypothesis was: "there is a gender difference to the degree of SOC, attitude to grades, and perceived stress level". The second was that "SOC and attitude to grades, predict stress in adolescents". To answer these hypotheses, a questionnaire survey was carried out among upper secondary students, 95 boys and 89 girls. The result of the analysis showed a significant difference between the gender.

The goal of this project was to implement and compare Invere Discrete Cosine Transform using three methods i.e. by bit parallel, digit serial and bit serial. This application describes a one dimensional Discrete Cosine Transform by bit prallel method and has been implemented by 0.35 ìm technology. When implementing a design, there are several considerations like word length etc. were taken into account.

As computerized communication and the Internet have evolved, the possibility to express and affirm one?s identity in new ways has also been created. Facebook, which has taken a leading role among the social fora on the Internet and succeeded worldwide, is my choice of study due to the number of people that actively choose to present themselves on it. The purpose of this thesis is to study the identity construction on Facebook through the activities a member partakes in, as well as how the presentation of oneself is written and if it is a result of a self-reflective process of the individual.The rationale for the qualitative study has been personal interviews in order to get an insight into how the individuals use and present themselves on Facebook and - in the interaction with others ? how they construct their own identity. My hypothesis has been that we, in the interaction with others, have a great possibility to create and understand our own identities. The study results show that identity formation is a constant process and that it is indeed a self-reflective project.

In 1992, the European Union began institutionalizing the cooperation against terrorism within the EU structure. Since then, this cooperation has gone through a number of changes. From a historical institutionalistic point of departure we explain these changes by identifying sources of institutional resilience and institutional change. Based on these results, we were able to pose hypotheses of when and what category of change was most likely to take place.The results show that the cooperation against terrorism within the EU was most likely to remain stable because of strong sources of institutional resilience. If change would occur through an increase in the sources of institutional change, it was most likely to be of a less extensive category.

The purpose of this essay was to examine and shed light on bullying as a groupprocess, a social phenomenon taking place in a school setting, to increase the understanding of the phenomenon. A theoretical overview of the litterature on bullying was made to investigate bullying and to give the reader a view of the researchfield. A total of 77 articles was studied. With the intention of studying bullying from a groupsychology perspective a metaanalysis was performed discussing groupphenomenon such as rolebehavior, responsibility, cohesiveness and norms in comparison to bullying episodes.Stemming from this analysis the question whether bullying can be view as a response to groupthink emerged. This question also constituted the secondary aim of this thesis.

An automatic control system for calibration of pressure indicators has been constructed. This control system can be used as a complement to the calibration system located at AerotechTelub, division MainPartner, in Linköping. The calibration system used today contains some not wanted pressure changes, which is compensated by hand today. The new system presented in this report automates the calibrating process and simplifies the calibration. Suitable hardware as motor, controls card and so on have been found and software in the form of Visual Basic program has been developed.

The calf extrator?s function has been studied, through measuring traction and how this varies in different situations, in comparison with corresponding manual traction situations. This was done against the background that excessive force at assisted calvings at dystocia can mean life threatening damages on the calf such as grave acidosis, vertebral fractures, femur fractures and rib fractures. The calf extractor has earlier been measured to pull with greater force than the established maximum force of ?two strong men?.

The goal with this project, was to explore the producing of a musicvideo with a synergistic focus in a practical way. Beside the practical work with the recording and editing of music and video, I wanted to explore the sound engineers role in such a project? To my help I had the video producer Hannes Knutsson from the small film- collective Lefvande Bilder and the singer, guitarist and songwriter Conny Flink. The result of my work is a musicvideo published on the internet website YouTube and the report of the making of it along with my work around the question above is published in this report. The name of the recorded and filmed song, written and performed by Conny Flink is ?My Way?. .

Our study illustrates health communication in order to find out how widespread the knowledge is about osteoporosis and how to reach out with health information to the public. Our essay was conducted through quantitative surveys, which included 402 respondents. This in order to highlight the prevailing uncertainty about the public disorder osteoporosis, which is common in Sweden. We wish to examine trough which channels our respondents choose to collect their health information. The thesis framework includes theories such as McGuire?s ProcessingTheory, Agenda setting, Two-step hypothesis and Diffusion of innovation. Through these theories, we analyzed our empirical data that emerged. The results showed that our respondents had very low knowledge of osteoporosis, although theyshowed interest for health information. The results also showed that respondents were consistent intheir actions regarding which channels they came to turn to. They prefered their health informationfrom news papers and family, friends and work colleagues. When asked where they got their information from, the respondents answered mostly from family, friends and work colleagues, followed closely by newspapers. This shows that respondents are more receptive to informationfrom the channels of their own choice. The results also showed that the propensity to change behavior increases with the age of the respondents..

The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.

Impression of reality deals with the subject of wearing a mask. It is an exploration of the idea that we are all playing different roles, on a stage in front of an audience. The aim was to work conceptually with text, photo and video as a way of exploring a subject. The goal was to create and edit the material so it would be interesting for the visitor at the graduation exhibition. The content was created through experiments based on questions such as the following examples; What is a mask? How can content control form? What is originality? The process resulted in a publication and a video installation with the ambition of highlighting the idea of the world as a theatrical construction.

In my project I have collaborated with Linda Larson, who is the creator behind the fashion brand Elveel. The goal was to produce an identity and a graphic profile for Elveel. The aim was that the graphic profile would act as an extension of the clothes aesthetics. I wanted to explore if I by different folding and cutting techniques, in tags and packaging, could reflect the details of the clothes expression. But also how different design elements can reflect the story behind the clothes.

In this research our goal is to conclude the aspects of interactivity which can prove to be important during the creation of a website. The focus in this essay is websites functioning as travelingguides, because we live in a time of traveling, experiance and learning. How can an analyzing method of websites be shaped? What can an analyze of interactivity on current travelingguides provide for recommendations by the creation of interactive travelingguides? The analyzingmethod is based on three shapingmethods and a poll that was answered by both national and international people. The analyze gave us quite clear results, if you follow the basics of Use Case, Personas, Usability and design, the website will have a bigger chanse of attracting people than if it doesn't..

This report is intended to give an insight in the Network Performance Assessment Modeland the parameters that is needed in the making of a fictitious grid that represents anoptimal grid. A main goal is to investigate how the construction of a real grid iscompared to the fictitious.One of the key parameters is how redundancy is treated in the model and to find theoptimal amount of redundancy versus the costs. Further is the dimensioning of the grid ofinterest. The fictitious grid is based on energy whereas the real grid often is based onsubscribed power and these two principles are compared and analyzed.The difference in the outcome of the model result due to variations in input data of themodel is also discussed in the report..
