Denna högskoleavhandling beskriver konstruktionen av ett system vars funktion är att PID-reglera ett linjärställdon kopplad till venturi. Syftet har varit att få fram en reglering på venturin så att förutsättningarna förblir desamma vid mätning av olika temperaturer och lufttryck i en testrigg. Denna testrigg används för att utveckla produkten Varivent som används för att uppfylla högre miljökrav på förbränningsmotorer.I arbetet beskriver jag de olika krav som funnits för att bygga det nya systemet, dessa var ingångar, utgångar, mikroprocessor, reglering,kommunikation samt övriga krav. Jag diskuterar de svårigheter och möjligheter som är förknippade med kraven och tar även upp de komponenter jag använt samt deras egenskaper. Det svåraste momentet har varit PID-regulatorn som både varit en viktig och en svårlöslig del i konstruktionen av systemet.

The information technology development that has occurred over the past decade has broughtmajor changes into people?s lives. We have gotten used to being constantly connected to theInternet and always having access to information through mobile technology. This has led tochanges in education and more and more courses have become available through Internet. Theseweb-based educations are nowadays very common in schools and in the business world as theyprovide increased flexibility for the user.Habiliteringen Lundbystrand has seen the potential in this kind of education and believes this isan opportunity for them to rationalize their work by replacing parts of their education for parentswith a web-based education.

During the last ten years, PIRLS and PISA have evaluated the reading levels of children and youth around the world, sometimes with grim results. The Swedish evaluation show a constant decline in reading comprehension, and Sweden, which from the start produced one of the best results in the world, have plummeted to the bottom of the ranks. The librarians of the public library have extensive experience of working with different projects engaging children and youth in reading, and so they have a major part to play in this matter. Consequently, the aim of this study is to examine and describe the different perceptions the public librarians have of these projects. Four research questions were formulated, each focusing on the perceptions regarding different aspects of the reading promotion projects.

A good flow of information in organizations is one of the key aspects of how we define a well-functioning organization. The information flow could be internal as well as external between actors within as well as outside of the organization. In a logistics organization this flow of information is equally important as in any other kind of organization. In this paper we have explored information flows in logistics organizations by applying, boundary spanning and the mobile-stationary divide perspective. In boundary spanning the main goal is to erase or relocate some of the boundaries within an organization, in our case to make the flow of information internally as well as externally better.

There has been an increase in the importance and amount of information concerning publicly traded stocks in recent years. When analyzing and valuing stocks finding new ways of collecting information has therefore increased in importance. This thesis aims to explore how meetings with management can impact the stock valuation done by the security analysts. Furthermore the case study examines what kind of information analysts can receive by interpreting management at these meetings. This case study of ten Swedish security analysts show that the analyst?s stock valuation is directly or indirectly affected by the meetings.

The large number of surrendered and feral cats is a big animal welfare problem all over the world. Populations of feral cats arise through a large number of unwanted cats which can lead to surrender of these, through cats allowed to roam free outside which can lead to the owner losing these and through the reproduction that occurs amongst these surrendered or lost cats. One aim of this study is to give an account of this problem. It is however difficult to draw general conclusions about these populations of cats since studies all over the world has been carried out on different types of populations, during different conditions and different periods of time. The welfare of many of these cats is presumably low because they are exposed to risks as disease, starvation, climate, traffic, other animals and humans.

This essay aims to show how Clarice Lispector uses a double narrative to wright beyond the rules of representation that are given for all literature. All writing is determined by the social hierarchies that exist in a society, and thus the essay shows how Lispector uses a specific literary strategy in order to give voice to a character that would otherwise be invisible. Using the philosophy of Michel Foucault and Gilles Deleuze as a means of contextualization, the essay further discusses the social and political impact of Lispectors novel.Through a thematic close reading of the novel The Hour of the Star the essay aims to deepen the understanding of the unique characterization in the novel and its implications. The first chapter is devoted to an analysis of the first person narrative in the novel and its development into a extra diegetic narrative. The second chapter aims to go further into the narrative with an analysis of the dichotomy between body and thought and its interplay with the two main characters in the novel.

Under vårt sista år var vi intresserade av att ta reda på de problem som vi kan stöta på i våra yrkesroller som fartygsingenjörer. Arbetet tar upp de tekniska problem som uppstår p.g.a. de allt strängare kraven på minskade svavelutsläpp från fartyg. De tekniska problemen härstammar från de olika bränslekvaliteternas vitt skilda egenskaper. Som svar på dessa problem har det utvecklats tekniska lösningar varav två stycken har tagits upp i detta arbete.För att ta reda på vilka tekniska problem som kan uppstå tog vi del av den berörda utrustningens tillverkares erfarenheter enligt empirisk modell.

In nature settings people often experience positive emotions. Litterature and theories about the positive effect of nature on humans are largely based upon visual impressions and aesthetic preference. The purpose of the present study is to examine how visually impaired individuals that lack visual impressions experience nature. The background is about what it means to be visually impaired and what it is like to be visually impaired in a nature setting, followed by a presentation of the five human senses and about stimulation of senses in healing gardens. That is followed by theories about the health promoting effect of nature, about why nature and therapeutic gardens make people feel good. After that theories about experiences and relations with settings are presented.

Kroppsmissnöje är mer utbrett hos kvinnor än hos män visar tidigare studier (Feingold & Mazzella, 1998) men även män börjar bli kroppsmissnöjda (Cash, Morrow, Hrabosky & Perry, 2004). Detta undersöktes tillsammans med självkänsla och kroppsjämförelse hos män och kvinnor och även de som har partner eller är singlar i ljuset av Social Comparison Theory och Cognitive Dissonance Theory. 133 personer testades med Body-Esteem scale, Figure Drawing Rating Scale, Self-esteem Scale och Universalistic Social Comparison Scale. Resultatet indikerar att båda könen är relativt nöjda men kvinnorna är något mindre nöjda med utseendet med sin kropp. Studien visar även att kvinnors idealbild är en smalare kropp medan männens idealbild är en muskulösare kropp.

This essay deals with the individual collecting of four individuals with different backgrounds and lives. The essay investigates what, how and why people collect. It provides a stepping-stone in moving closer to understanding one, in human nature, deeply rooted phenomenon - collecting.The essay is based on a list of questions made by the Nordic Museum in Stockholm. It also includes in-depth examinations of four person?s passion of collecting, in which four individuals were interviewed: a pig collector, a collector of Mickey Mouse items, a multi-collector of objects from other cultures and one collector of items related to the artist Madonna.

The purpose of this study is to identify a successful way of expanding a business on a global market, focusing on innovation products. An analysis was also made to see how internationalization theories are useful in businesses with innovation products. Four companies have been interviewed where two of them have innovation products (Proline AB and Q-Med AB) and the others are widely successful in exporting to a global market (Safegate Group and Weda Poolcleaners AB). Furthermore four interviews have been made with support organizations that have great experience in helping companies in this area (Svenska Uppfinnareföreningen, Almi Företagspartner AB, Exportrådet and The Swedish-American Chambers of Commerce).One of the results that can be identified is the diverse view and will to expand the business. The inventor often has a born global strategy in mind whereas the helping organizations rather expand step by step and only to one country at a time.

Den organiserade handeln av öl från Tyskland till Sverige är ett stort problem. Dels genom försäljning till ungdomar, privatpersoner, krogar och arbetsplatser dels genom förlorade skatteintäkter. Det går inte lägre att kontrollera konsumtionen av öl genom Systembolagets monopol. Detta problem kommer i framtiden att öka på grund av de ökade införselkvoter som träder i kraft år 2004. Det är svårt att komma åt problemet då införseln av öl är laglig, men inte försäljningen.

The purpose of this study was to investigate whether social counselling via chat conversations could meet the criteria for a professional conversation, and how the six social workers who were interviewed felt that it had affected the profession and the clients who are seeking their help.Communication, professionality, power, roles and regions are the key topics of this study. A hermeneutic approach has not only influenced the interviews but also the content analysis that was used to encode the results.The interviews revealed that the chat conversations was a successful tool but not entirely without difficulties. The initial contact making between the client and the social worker favours the client, since she/he remains anonymous and that was the main advantage of the method. The biggest concern however was that in the anonymity it is not possible to report cases that the social worker are obligated to. The changing of forum does not necessarily affect the professionality but due to the faceless chat conversation an entire dimension of communication disappears because the loss of body language.
