Strömmande video i trådlösa mesh nätverk : Streaming video in wireless mesh networks
This document?s content is the final report of the master´s dissertation Magnus Hällström did during springtime of year 2013. The dissertation?s subject is 802.11s wireless mesh networks with streaming video as a focus point. During the dissertation a wireless mesh network was set up with different attached cameras for streaming video. A sun panel solution was also tested with the goal of creating a package with a self-configuring network node streaming video, powered by nothing but solar energy. .

Användare från båda håll ? Utökat informationsstöd inom design av registreringsprocesser
During spring 2001 we have been involved with our bachelor thesis at Doberman
Digital Agency, an Internet related webdesign company. We have focused our work
on the registration process via digital medias such as the Internet. During our
workprocess we have been conducting a number of studies and analyses of
workrelated materials. Ethnographical methods such as structured interviews and
participant observations were primarily used in our work. We also widely used
brainstorming in our designprocess.
Sensorsystem till hinderhanterande robot
The projects goal is to construct and program a robot that is controlled from a computer but also have an obstacle handling function that allows the robot to navigate around the object by itself.The robot is a simple construction and the number of components and functions is kept at a minimum. A tricycle construction was chosen because it?s the simplest. Communication between the robot and the computer also kept as simple as possible..
Stereotyper i den virtuella världen. Hur visuella intryck påverkar deltagares uppfattningar av virtuella agenter
The purpose of this study is to examine how participants perceive virtual agents shown on a computer display. In particular, it is explored to what extent participants transfer gender and attraction stereotypes that are commonly applied in the physical world to virtual agents. Previous related studies have often explored only text or voice interfaces, without any visually appearing agents, and here indeed found evidence for a transfer of gender stereotypes. Our hypothesis was that the addition of a visual agent interface would reinforce this effect. The results support our hypothesis that participants transfer human gender and attraction stereotypes onto virtual agents, as well as that these processes are affected by the visual representations of the agents..
Stökiga pojkar och rara flickor!
The aim of this qualitative study was to examine bereaved individuals? experiences of support from their social networks and participation in support groups. The theoretical framework is based on theories about social support and parts of the attachment theory. Data were collected from four interviews and analysed by the study?s theoretical framework.
Agil projektmetodik - En studie av den agila metodiken och Scrums inverkan på IT-projekt
Denna undersökning syftar till att undersöka och utvärdera den agila
projektmetodiken med
inriktning på Scrum. Vattenfallsmetoden berörs även med avsikt att tjäna som
kontrast till agil
projektmetodik och Scrum. Att arbeta utefter en specifik projektmetod eller
anamma ett agilt
förhållningssätt kan bidra till att rätt produkt utvecklas och att undvika att
projektet misslyckas.
Undersökningen baseras på tre grundpelare; litteraturstudie, intervjuer och
undersökning av
befintliga studier. Dessa ligger till grund för de resultat som presenteras och
diskuteras i uppsatsen
med avsikt att kartlägga förekommande fenomen i projekt bedrivna efter en agil
metod. I uppsatsen
redogörs för och diskuteras resultatet av bedrivna intervjuer med personer i
IT-branschen samt
resultatet av befintliga studier utförda på bland annat Microsoft och Adobe
Systems.

"Halfpipe Active Channel"- developing a secure communications protocol
With the advent of powerful multimedia capable mobile phones, the market for mobile services is flourishing. Zenterio AB's Halfpipe Active Desktop is a complete distributed mobile service platform a with a powerful server and platform-independent client. The communication between the client and server takes place over a GPRS-capable mobile network. The purpose of this thesis is to develop a secure communications protocol for use between the Halfpipe Active Desktop client and server. This is done by determining requirements, analyzing candidate protocols and then by designing the final protocol.
Säkerheten i trådlösa nätverk
The number of wireless networks has increased rapidly among both home users and companies in just a few years. That has brought a lot of good things with it, for example the possibility to connect wireless equipment to the network or Internet from an arbitrary position within range of the accesspoint. But since the transmissions take place through the air some new security risks appear. It?s difficult to restrict the signals to a specific space and thereby a lot easier for unauthorized to eavesdrop or disturb the signals compared to a traditional wired network.
Prestanda och precision pa? en enkortsdator i ett system med realtidskrav
The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.
?Läser science fiction utan att skämmas?: Om kvinnors läsning av science fiction
The purpose of this Master?s thesis is to investigate the female reader of science fiction literature, a genre by tradition dominated by men. Through qualitative interviews with seven female science fiction readers, the relation between the reading and the readers? lives, as well as their concepts of the science fiction genre and the community of science fiction readers, was examined. The main theoretical framework used for the analysis was Yvonne Hirdman?s gender theory, Judith Butler?s concept of identity and Louise M.

Från NV till NO
This paper deals with how science teachers in the Swedish secondary school choose the content in the education they give to the pupils. What are the reasons for their choices and what do they think of the purpose of science in secondary school? Through interviewing science teachers the investigation shows that there are three different views of how to choose content in the science education: one focuses on the processes of science itself, one integrates the socio-cultural aspects and one emphasizes the interests of the pupils.
