I detta exjobb har en testplattform skapats för att kunna testa, utvärdera och jämföra olika pumpstyrningar i torr miljö. Testplattformen består av en simulerad pumpstation till vilken befintliga pumpstyrningar av valfri modell kan kopplas, det vill säga ett Hardware-In-the-Loop-system. De främsta fördelarna med en sådan plattform är flexibilitet, snabb feedback samt möjligheten att återskapa exakt samma förutsättningar för olika pumpstyrningar.Testplattformen har implementerats i LabVIEW på en PC som kommunicerar med pumpstyrningshårdvara via ett I/O-kort för analoga och digitala signaler.Det simulerade systemet konfigureras genom val av bland annat pumpar, pumpsump, inflöde och rörsystem. Utifrån de inmatade värdena och styrsignaler från pumpstyrningen simuleras sedan bland annat systemets flöden, energier och temperaturer. Nivån i sumpen, och övriga insignaler till pumpstyrningen, återkopplas från simuleringen.

The usage possibilities of mobile platforms and smart phones are increasing rapidly as they provide support for better processors, sensors and communications capabilities. This has for many companies resulted in an increased interest to explore the possibilities of mobile platforms and how they can be integrated in various business areas. As the usage of mobile platforms in industrial applications is a new area, it is difficult for companies to estimate their potential, and what contributions the different platforms can give.This master thesis investigates the possibilities and limitations for the consultant firm Combitech when integrating mobile platforms and handheld devices in industrial applications. This is accomplished through a comparison between the platforms and by considering the possible areas of use for the mobile platforms based on experiences from companies and research in the area.For a company with the intent to deliver services that use mobile platforms, it is important to be able to combine expertise and resources to effectively attract customers. The mobile platforms will, if applied right, give great possibilities in industrial applications as a cost-effective alternative for both hardware and software solutions for businesses, which provides an opportunity to sell services to both established and new clients.

Today electronics becomes more and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a big gap between the degrees of automization for the two parts and makes the analog parts the bottleneck in electronics develop. Research is ongoing at Electronics systems group at Linköping University target the increase of design automization for analog circuits. An optimizationbased approach for device sizing is developed and for this a good optimization method is needed which can find good solutions and meet the specification parameters.

Blogpics ? young girls views on photography online Young people create new forms of social interaction on the internet, and in Sweden, especially young girls, have become very active bloggers. Girls write, publish pictures and build networks with, mostly, other girls.  This new phenonomen has been described in Swedish media partly as a problem, where adults are worried that the information the young girls publish about themselves is too personal, and can be used for the wrong purposes. It has also been suggested that the content of young girls blogs has little value, beeing mostly narcissitic, superficial and obsessed with fashion and shopping. The purpose of this paper has been to investigate how young girls reflect upon their photographic communication on the internet.  The idea has been to ask the girls themselves about their own experiences, to get a more complete picture of them as internet users, to investigate their communication strategies and solutions when it comes to net integrity  and to talk about how they create gender and identity online..

Streaming is a big field in todays digitalized society. The streaming market is huge, both in regards to the customer base, but also in regards to different providers and their stakes within this market. But how does the different providers go about in order to provide their users with added value? What does the user prioritize? The purpose of this study is to examine which additional functions can be considered important when designing a streaming service, which in turn will create an added value for the user. The study is based on a qualitative study of 6 individuals with semi-structured interviews and we will present an in-depth analysis regarding four fields of interest to us in regards to streaming services; second devices, recommendation systems, keywords and social connectivity.

The purpose of this Master?s thesis is to examine the information needs of reporters at a Swedish daily newspaper, and see if they are met by the information resources provided by the newspaper. It examines if there are resources which are not used and why. The examination is based on Henczel?s model for information auditing.

The purpose of the study is to contribute to the field of social access in children's free play in the pre-school class, by looking at how children are included and excluded and how power structures arises in the free time. In order to capture the events that occur among the children, observations were chosen as research method.The results show that the children wanted to play with each other, and that the most common way to facilitate play was to ask "Can I join?". There were also other strategies being practiced regularly. It was also common to exclude other children from playing, and this was especially when the children wanted to protect their ongoing game, or that someone was not allowed to join because he or she ruined it for the others.

The main purpose of a Flight Data Recorder (FDR) is to facilitate the investigation of incidents. In order to interpret the data that has been recorded in the FDR the data has to be visualized in some way. This can be done with software on a computer or with hardware that is specific for the model of aircraft that the data originates from.The aim of this project is to visualize data for six parameters from the FDR of Saab 2000 in an avionics rig. The avionics rig resembles the cockpit of Saab 2000 and the displays in it are identical to the ones found in the plane. All six parameters are shown on the same display.Due to safety regulation vital systems in aircraft are doubled, with one system on the left side and one on the right.

Syftet med denna studie har varit att granska den forskning som fanns beskriven i vetenskapliga artiklar omkring de problem som uppstår och de upplevelser som kvinnan får vid insättning av spiral. I en litteraturstudie valdes sju artiklar ut och deras vetenskaplighet studerades. Alla sju artiklarna var baserade på kvantitativa studier. Resultatet visade att smärta tillsammans med spiralinsättning var mycket vanligt. Den kategori av kvinnor som upplevde mest smärta var de kvinnor som inte hade fött barn på det naturliga sättet.

Projects of all kinds generate documentation that needs to be organized and stored for future use. Well adapted tools, together with a unified modus operandi need to be available for both the project members and those having a more organizing role if an organization is to be effective.A study of the tools available to project members at Svenska Kraftnät have been performed along with an analysis of the guidelines for the tools' usage. The study has focused on the needs of the project members, not the organization as a whole, thus providing a bottom-up approach to the problem instead of the more organizational top-down approach. Interviews of around 20 project members, whose roles include project leaders, technical experts and documentation supervisors, have been conducted to get an idea of the practical problems that exists.All systems, except for a local network storage device, were found to at least meet Svenska Kraftnät's current demands. The usage guidelines, however, covers only the general process that a project should follow and lacks detailed information on a per system level in several areas.

The Promised land ? A letter analysis of America letters from 1850-1870 This essay is about the Swedish emigration to America. This essay will focus on the period 1840-1870, where the main focus will be the american civil war, and what the immigrants wrote back to their relatives in Sweden. This study will also focus on the integration of Swedish immigrants.My main question are what did the swedes write back to Sweden during the war? And how did it differ from the period before and after the war?But also can a war assimilate a immigrant faster than it would be done without the war?The conclusion that has been made is that the war did help the swedish immigrants to integrate much faster than usually.

Microwave is a time- efficient device for heating and reheating of foods. Despite the fact that its effects on foods have been evaluated during a long period of time, without any more negative effects shown compared to conventional cooking, one third of the Swedish population believes (in 2010) it accounts for a higher loss of nutrition. This literature review aim to compile studies regarding how food is affected by cooking in microwave, with respect to cooking losses, nutrition, secondary metabolites as well as sensory and textural aspects and compare it with conventional cooking. The compilation shows that different combination of effect (W), time and amount of water during microwave cooking have different effects on foods. The contents of proteins, vitamin B and carbohydrates are generally higher after microwave cooking, while anti-nutritional substances are affected much less during conventional cooking. This also depends on if it is of animal or non-animal origin. However, for the majority of nutrition values the differences are quite small.

Computer Forensics investigations have become more and more common while investigating IT-related issues. From experience, hard disks, USB thumb, memory sticks contains information that might be useful. Computer Forensics is regulary conducted by Police, Customs, Tax investigators but also within private companies and organisations. However, there are areas within the storage device that are not part of the organisied structure that a file system gives. The reason for that might be that the information has been erased by intention, a virus destroyed the file system and so on.
