The purpose of this master thesis was to study the water system for mechanically cleaned water at Skärblacka mill, in order to find and evaluate possibilities of using energy more efficiently. The thesis also includes an evaluation of the software tool ?Pumpanalys?Skärblacka mill produces pulp and paper. The large amount of water required is cleaned mechanically through filters and called mechanically cleaned water (MR0). The MR0 water is pumped out to the factory by four crude water pumps.

This report describes a final thesis done during the spring of 2008 as part of the bachelor degree in computer engineering degree at the School of Engineering in Jönköping.The client is working in the consulting business and is involved in, amongst others, work regarding information security. Within this field they perform so called Threat, Risk and Vulnerability assessments. Today these assessments are done by a predefined method, but many details are controlled by the person documenting the project. A wish was made that the implementation was standardized, it should also ease the task of estimating the need for time and money. The solution for this seems to be a software tool.

När de traditionella skrivbordsapplikationerna görs om till webbapplikationer, ställer det krav på JavaScript som används mer och mer för att få fram ett responsivt gränssnitt på webben. För att underlätta utvecklingen av JavaScriptapplikationer har ett antal funktionsbibliotek skapats. I vår studie undersöker vi därför vilket av de två populäraste JavaScriptbiblioteken idag, jQuery och Prototype, som presterar bäst i dagens mest använda webbläsare. Dessa tester har utförts i ett testramverk som vi själva utvecklat för att vara webbläsaroberoende och inte kräva något av de bibliotek vi testar. Testerna är uppdelade i fyra testfall som körs 20 gånger för att ge ett mer tillförlitligt resultat. Vi har testat hur varje bibliotek hanterar traversering och manipulation av DOM-trädet, sätter och hämtar stilar och attribut på element i DOM-trädet och hanterar event på element i DOM-trädet. Testerna visade att biblioteket Prototype presterade bättre på alla utom ett testfall i majoriteten av våra utvalda webbläsare; det enda testfallet där jQuery presterade bättre än Prototype var där DOM-trädet skulle manipuleras.

This Bachelor Thesis in the area of Computer Science and Work Science describes the process of design and development of an IT-tool between the municipality of Ron-neby and TietoEnator a development and consultancy firm, the Gothenburg office. The thesis focuses mainly on the cooperation between the consultant designer and the local municipal. Through cooperation, the organisation is incorporated into the tool and the tool is incorporated into the organisation. Concepts that are central in this thesis are design, cooperation and tailoring. A question raised is, if distance work and extensive cooperation might be a good way of working in the process of design and development, when the organisation is being incorporated into the tool.

Ambitionen och målet med mitt projekt var att visualisera delar av en berättelse med hjälp av den senaste datortekniken. Detta tog sin form av en 3d-animation. Målet var inte att producera en färdig kortfilm utan att arbeta med utvalda delar. Projektet var indelat i tre block; en planerings- och researchfas, en produktionsfas och en reflektionsfas. Stora delar av magisterarbetet har bestått av att producera innehåll som sedan ska analyseras. Med arbetet vill jag att folk ska få mer förståelse för 3d-tekniken som ett flexibelt och intressant konstverktyg.

The purpose of this thesis is to investigate what functions the public library has for parents of small children. If and how they make use of the library and what their opinion is about it. The research questions are: Which functions does the public library have for parents of small children? How do parents of small children use the library and what opinion do they have about it? Which factors have an impact on the parents of small children and how do they influence their use of and opinion about the public library and the functions of the library? The theoretical approach is based on Henrik Jochumsen and Casper Hvenegaard Rasmussen?s model of the social room and the lifestyles and Marianne Andersson and Dorte Skot-Hansen?s model of the public library?s functions. To answer our research questions we have made seven qualitative interviews with parents of small children.

This master thesis has been carried out at Scania R&D at the department for Powertrain Control System Development during the winter of 2010/2011. In the thesis the writer examine and evaluate the existing method for collecting information from the tests carried out during the development of the Powertrain Control Systems software. It also contains suggestions for how a new method that enhance the validation elements could look like.The master thesis uses Vicentes theories of the ecological approach and theories of how knowledge sharing of tacit and technical information works within an organization and between the organization and its customers. First a workplace analysis at Scania R&D is carried out to see how Powertrain Control Systems work and how they test their software. Second a control task analysis, where the aims decided on after the interviews, is compared to the existing method.

Since the beginning of the 1990s, Swedish society has gone through a great change. Firstly with the personal computer and then with the internet moving in to everyday life, a new arena for interaction with society evolved. Work, education, doing bank errands and reading or discussing the news, just to name a few, now all take place in the virtual world online. Not to mention social media sites such as twitter, instagram or facebook, the last of which has over half of the Swedish population represented as members.   Companies, corporations, interest groups, political parties and politicians must be aware of the massive impact that a post spread through social media can have.    This thesis will, with the text analyzing tool, argumentation analysis, and on the theoretical platform of political communications theory, analyze three of the most viral Swedish political posts spread over 120 000 times each, to see if there are any combined qualities that point to the fact that there is a formula for getting a post to become a viral success on social media.    The main result showed that of the three posts analyzed, all were built up around a factual thesis, argued for with foremost example arguments, not only appealing to the logical branch of argumentation but also to the ethical, and that they tended to be of high relevance and sustainability. The conclusion must therefore be that these are all qualities that tend to be of relevance for making a political post on social media into a viral success..

The purpose of this paper is to see how politicians use Internet communication in their daily work and how they use it to interact with citizens of Vasteras city. To reach my conclusions I used both theoretical methods such as literature studies and qualitative interviews with the towns 11 trustees. Accoarding to this study the politicians saw not only a lot of potentials and advantages in Internet communication but also many difficulties and obstacles. In this case the cons far exceeded the pros. One of the main reason is the bad experiences which caused by rasist attacks/threats made to politicians and also the difficulties in handling of sensitiv documents which was seen as a stress factor.

The aim of this master thesis is to examine the identity of librarians. We have done this by conducting a text analysis where we have analysed texts produced by DIK, the major union of librarians, and by Library and Information Science departments in Sweden. The material we have analysed is texts produced in the aim of introducing and marketing the librarian occupation and education. The aim of this study is to find out how the identity of the librarian is expressed in this material. We have conducted the text analysis by adopting the critical discourse analyst Norman Fairclough´s theories.

Syfte med denna fallstudie är att undersöka hur användarnas medverkan vid anpassningar av gränssnitt för ett processtyrsystem påverkar användbarheten av denna. Eftersom det är gränssnittet som användarna interagerar med är det viktigt att användarna involveras i anpassningen vid införandet så att hänsyn tas till deras behov och önskemål. I min fallstudie valde jag att undersöka processen för användarmedverkan vid anpassningen av ett grässnitt för ett standardstyrsystem ur användarnas perspektiv. Undersökningen är baserad på ett stort företag med ett nytt system för styrning och övervakning av tillverkningsprocessen, som nyligen implementerades dels på en befintlig produktionsenhet och dels på två nybyggda produktionsenheter. Olika kategorier av användare(operatörer)har kunnat identifierats: de som har erfarenhet av användning av ett sådant system och aktivt medverkat vid utformning av användargränssnitt, de som har erfarenhet men inte medverkat aktivt och de som inte har särskilt mycket erfarenhet av system användandet överhuvudtaget.

Uppsatsen behandlar hur två organisationer samarbetar och koordinerar deras kooperativa arbete med hjälp av en artefakt. De två organisationerna är Marinmuseum och Turistbyrån där deras kooperativa arbete handlar om att skapa guidade turer tillsammans. Vi har jobbat mot målgruppernas målsättningar, behov och krav för att hitta det ultimata stödet för deras verksamhet. Syftet är att förmedla förståelse för hur organisationerna idag använder artefakten i deras gemensamma arbete, baserat på intervjuer och observationer. Huvudfrågorna i vår studie har varit: Hur kan vi som utvecklare kan stödja de två olika organisationernas samarbetsmöjligheter och förbättra koordinationen i det fall då de använder denna artefakt, deras pappersbaserade bokningslista som primär informationsplats? Hur kan denna artefakt ersättas utan att tappa dess koordinations och interaktions förmågor samt flexibilitet? Studien har visat att den pappersbaserade artefakten, deras bokningslista, innefattar många positiva egenskaper som vid digitalisering måste tas hänsyn till.

A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.

System specialists and technicians will use the prototype. The Simulator should give the user a technical demonstration on how components work in a door system. The proto- type consists of motor, switch, relay and sensor.

This report describes a master thesis performed at SICS (Swedish Institute of Computer Science) and KTH (The Royal Institute of Technology) in Stockholm.Ajax stands for "Asynchronous JavaScript and XML" and it's not a programming language, but a suite of technologies used to develop web applications with more interactivity than the traditional web pages.Ajax applications can be adapted for mobile and constrained devices. This has been called Mobile Ajax. While the technique is the same, Mobile Ajax generally is considered to be a special case of Ajax, because it deals with problems specific to the mobile market.The purpose of this thesis has been to examine which possibilities and disadvantages has the Mobile Ajax from developers and users perspective. In addition we compare Mobile Ajax with Java Micro Edition (Java ME) and Flash Lite.This has been done through literature studies and development of a databased chat client (MAIM -Mobile Ajax Instant Messenger). The application sends and receives direct messages in real time between differently mobile devices.
