There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

Our project is divided into two parts, one production and written report. The main focus was the production part, were we used PHP to create simple solution for handling SMS and MMS with direct communication with the mobile operator server. We communicate with sockets and can handle CIMD2 and MM7 protocol. To get our components easy to use we have created two classes to handle SMS and MMS. To demonstrate our technical platform we created a website were you can create an account.

Electrolux Laundry Systems is the world leader in manufacturing professional laundry equipment.The machines are used in the hotel sector, elderly care, in multifamily houses, laundry bars, and incommercial and institutional laundries.If there is oil or grease left in the clothes after washing may the heat from the dryer cause a chemicalreaction. This reaction may, under certain circumstances cause a fire inside the drum. Competitors toElectrolux has developed its own systems that extinguishes fire inside a tumble dryer and customershave expressed desire to purchase a fire-extinguishing system. Therefore, the project team receivedthe task by Electrolux to develop a fire-extinguishing system that extinguishes a fire in a tumbledryer.The purpose of the project has been to develop a system that both detects and responds to fire in anindustrial tumble dryer to meet the competitors and to satisfy customers' requirements.The goal was to develop a fire-extinguishing system for Electrolux Laundry Systems and develop afully functioning prototype.The project began with information searches on a variety of methods to both detect and extinguish afire. Subsequently, a number of different methods were used to develop a final solution and make aprototype.The result of the project is a fire-extinguishing system that extinguishes a fire inside a dryer.

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.

Citizens? freedom of choice has been a subject of debate in Sweden for over 30 years. This study focuses on decision making processes among patients within the Swedish healthcare system. The main conclusions are that in contrast to how patients? freedom of choice is described within governmental bills and governmental inquires and reports, patients are not following the steps included in the rational model of decision making.

Sedan sensommaren 2008 har en global finansiell kris drabbat världen. Det blev turbulens på den finansiella kapitalmarknaden vilket även har drabbat de Svenska bankerna. Syftet med denna uppsats är följaktligen att beskriva hur de svenska bankerna har agerat för att hantera den finansiella krisen. Undersökningen innefattar tre av de största bankerna i Sverige, Handelsbanken, Nordea och Swedbank. Teorier inom krishantering ligger till grund för den modell i fyra steg (Krisförberedelse, Krisidentifiering, Krisåtgärder och Lärdomar) som sedan jämförs med hur bankerna har agerat.

This report describes a system for verification of fingerprints against a previous created template. It describes how and why a fingerprint image must be processed before it can be used to either identify or verify a person. The method is based on special features of a fingerprint, called minutiae points. The whole process from image to matching is described, every step in the process with image enhancement, binarization, thinning and how to find the minutiae points. Also what false minutiae points are, how they arise, why they deteriorate the result, and how to handle them, is discussed.

In contemporary global environmental governance stakeholding, as a means for defining legitimate participants in democratic decision-making, has become of great importance. In this essay I deploy the concept of ?the stakeholder perspective? to denote arguments that all stakeholders ? defined as carriers of particular interests ? should be able to participate in political decision-making affecting their interests. The purpose of the essay is to analyze the stakeholder perspective's potential to change environmental politics. Departing from the philosophy of Heidegger, I develop a theoretical approach that separate the concept of the political from that of politics.

De svenska städerna har genomgått en omvandling gällande synen på kollektivtrafik. För hundra år sedan var spårvägen det vanligaste kollektiva färdsättet. Sedan dess har städerna genomgått stora förändringar men det intressanta är att allt fler städer väljer att gå tillbaka till spårvägstrafik. Detta fenomen ville jag undersöka lite närmare och resultatet är dettta kandidatarbete med Malmö som föremål för fallstudien.

Vanligtvis har de flesta vuxna svenskar na?gon typ av relation till en bank. De svenska storbankerna erbjuder alla likartade tja?nster och produkter. Ett av bankernas stora konkurrensmedel a?r ra?ntorna, dock a?r det inte stora skillnader mellan ra?nteniva?erna.

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

The conflict over Western Sahara is primarily a conflict over sovereignty, with Morocco on one side claiming territorial rights, and the Polisario Front on the other side claiming popular sovereignty. The conflict has till this day not been resolved and is in a dire need of a solution. In order to determine which solution is the most appropriate, an understanding of all the complex aspects of the conflict is required. In this context, the study aims to examine the conflict in a globalized setting by analyzing how the American news agency AP News portrays the conflict. The US media conglomerate was specifically chosen due to its dominance over international information flows.

 Uppsatsen är av teoretisk karaktär och utforskar tekniker och teorier kring ämnet statisk spelbalans. Som praktiskt exempel används spelet Testament. Texten och balanseringsarbetet med Testament är en produkt av Erik Sjöstrands examensarbete under vårterminen 2009 vid Högskolan i Skövde.Texten presenterar vad statisk spelbalans är och dess syfte. Återkommande termer är att alla val som finns i ett spel ska vara betydelsefulla och att man ska sträva efter att alla som spelar spelet har samma förutsättningar.Tekniker som presenterar och anpassas till spelet Testament är: kunskap om balans och obalans, spelbalans beroende av spelarnas skicklighet, symmetri och asymmetri, transitiva och intransitiva system, modulär design, fail-safes, global balans, samt prototyper och speltestning.Slutsatsen är att det inte går att säga huruvida Testament är balanserat eller inte, att det går att anpassa tekniker för att balansera flerspelarspel till att balansera enspelarspel, att statisk spelbalans bör genomföras under alla faser av spelutvecklingsprocessen, och att de som balanserar spel måste ha god förståelse för de spelsystem de balanserar..

Employees of the criminal correctional system have a duty to notify social services if they suspect that children are exposed to maltreatment, according to Chapter 14, § 1 SoL. Despite the obligation to report, studies show that this is not done at all times. The purpose of this paper is to describe and analyze how the criminal correctional system in Kalmar looks at notification if they suspect that children are exposed to maltreatment. To examine this, we used qualitative research method based on semi-structuring interviews; these were carried out with six employees, working in the criminal correctional system. The answers that emerged during the interviews have been analyzed using Yeheskel Hasenfeld theory of human services organizations, and trough previous research.
