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.

By analysing Still the water (2014), Radiance (2017) and True Mothers (2020) by Naomi Kawase this essay will look at her work to see how she portrays the experience of being a woman in relation to her community. Looking into her way of using the camera by applying the theory of haptic visuality allows the spectator to identify themselves in a bodily relationship with the image. By using the camera to closely frame objects of importance for the characters, Kawase leads the spectator to understand the world of the film and enables a more profound understanding of their experience. For the community to be of importance for the women it must be founded in the feeling of security and a confirmation of their feelings. Once secure, the women can express themselves and by that, feminist politics..

When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.

The aim of the thesis is to identify and investigate central themes in two video artworks, Poliisi and Pink Ball, by Swedish artist Annika Larsson. Moreover it is an investigation of the configurations of violence, and an enquiring whether these works have a social-minded intention.Elements in scenery, framing and narration are analysed with the term ?crystalline regime? (régim cristallin), described by French philosopher Gilles Deleuze, which defines the artificial as opposed to the purely representational. Processes within the narrations of the two works are analysed as rituals, which leads to an investigation of an internal sign-system and to the question whether the rituals in these works have a function. Theory by French philosopher Georges Bataille is used to analyse the ritual with no external purpose, which aims at an intense experience of life.

I animation för film kan regissören ändra kameravinkel för att en karaktärs känslor ska förmedlas på ett tydligt. i ett spel har ofta spelaren kontroll över kamerans position men kan i vissa fall inte ändra kameravinkeln. I det här arbetet undersöks om en spelkaraktärs rörelser måste överdrivas mer i ett spel som använder Free Roaming Camera än i ett spel som använder First Person Perspective. En karaktär i ett tänkt spel animerades med olika grad av överdrift för att förmedla ilska. Animationerna visades sedan för ett antal informanter som fick bedöma hur trovärdiga de upplevde animationerna samt ange vilket sinnestillstånd de upplevde att karaktären hade.

Today many different types of lock systems are used all over the world. Passwords, finger prints and magnetic strips are a few examples. When the key is a three dimensional object, lika a physical metal key, the security depends, in a high degree, on that you can?t copy the object without access to it. One approach to copying the object is photographing the object, and from these photographs create a copy.

The main purpose of this thesis has been to find a way to evaluate the soil parameters for the Total sounding method (TS), such as the inner friction angles and settlement modules. This study only includes an analysis of soil profiles from the Stockholm region. The chosen location for the study is a proposed residential area east of Igelstaviken in Södertälje. Presently, the subject plot is located in a residential area and is also adjacent to a school area.Total sounding is originally a Norwegian soil testing method. The differences between the sounding methods (weight-, ram-, CPT-sounding) are for instance how the sound is driven into the ground and what kind of parameters that are registered.

AbstractTitle: Watching eyes ? for better or worse (Vakande ögon ? på gott eller ont?)Number of pages: 34 (41 including enclosures)Author: Josefine NybergTutor: Göran SvenssonCourse: Media and Communication Studies CPeriod: Autumn term 2007University: Division of Media and Communication, Department of Information Science, Uppsala University.Purpose/Aim: The aim of this essay is partly to make a study about how people understand camera supervise, and partly discuss what their opinions are concering the subject.Key Questions: Which or what is the mainpurpose of camerasurveillance? What does the public think about the subject? When can there be an insult against the integrity while using the cameras? What is private and what is public? What is the posibilities and threats in the future?Material/Method: A qualitative method has been used. Four interviewes, one personale interview with a policeofficer from Uppsala and three focusgroupinterviwes with people from Stockholm, have been done. Then the results from the interviewes have been compared with earlier theories and reaserches. By reading publicdocuments, press releases and reports from the government, I have gather information for the essay.Main results: Even if the public are aware of the cameras and knows that they allmoust allways are whatched by the electronic eye, they don´t seem to care that much about the constant surveillance.

This report describes a study, description and testing of parts to an application adapted to the operating system Android. The application is supposed to measure the distance to a car ahead. Apart from distance measurements the ability of the application to calculate its own speed with the help of GPS is tested. From these two parameters, speed, distance and some constants the theoretical stopping distance of the car will be calculated in order to warn the driver if the car is too close to the car ahead in relation to its own speed and stopping distance.Tests were conducted on the different applications that were programmed and the result showed that the camera technique in the mobile phone itself limits the maximum distance of the distance measurement application. The max distance the tests in this thesis revealed was approximately 5 meters.

This degree project has been carried out in cooperation with Gedevelop in Helsingborg.Gedevelop has developed a camera that can calculate the weight of a liquid glass mass.Because of the density and viscosity changes in the glass, the weight information issometimes incorrect given. Glass industry is today addressing the problem by an operatorperforming a manual weighing of a few bottles which, in turn, calibrates the camera system.The project aimed to develop an automated system to control the weighing of glass bottles forglass industries. This system must be so flexible that it can be easily mounted on plants withdifferent production equipment around the world.The project includes design and construction of equipment that meets the requirementsformulated together with Gedevelop. Work has been done both in Halmstad and Helsingborgand has included both calculations and review of the theory to understand the forces thatinfluence the design of different construction parts. A prototype was produced that meets theoperating requirements for the design and can be used in testing features.

The aim of the thesis was to provide further understanding on how Swedish consumers use the Internet as an information source in their purchase decision process. The subject was investigated from different perspectives: gender, product type and information type. The authors used a quantitative approach, and a survey (n=120) was conducted. It was concluded that men and women are equally influenced by traditional word-of-mouth, but more men than women search for product information online and they are more likely to let their purchase decision to be influenced by it. Women tend more to trust commercial sources.

Social control in different forms has existed in all known societies. This control has taken different shapes and expressions. In older smaller communities there was a collective control among the citizens. In modern societies the state is trying to control the lives of the citizens. These control mechanisms can be seen as both freedom-reducing and freedom inducing depending on which concept of freedom one upholds.

Many invasive species propose a big threat against the native fauna in the area that they colonise. Today the raccoon dog (Nyctereutes procyonoides) is speeding from Finland over the border in to northern Sweden. A project to stop the spread and eliminate the individuals that already have established was initiated in the autumn of 2008. To investigate areas that might be interesting for raccoon dogs and to confirm sightings, cameras with auto triggering mechanisms are used. To get the raccoon dog in front of the camera some kind of lure is used. In this study three kinds of different lures was tested against each other?s.
