Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.

Sweden is a country that has made some progress in developing energy efficient solutions. The problem in Sweden is that many houses and apartment buildings are old and have inefficient ventilation- and heating systems. This energy is lost when systems are inefficient, which then results in huge economic costs. Luckily, more and more people are becoming aware of this, which means that Sweden is on track to become even better within energy efficiency.Energy use for the housing- and service sector amounts to 166 TWh of total use at 616 TWh. Without distribution and conversion losses, these figures show that the housing- and service sector accounts for almost 40 % of the country's total energy consumption.

Marknaden för mobila system har utvecklats enormt snabbt de senaste åren. Idag är det ett område med en allt större omsättning och det har vuxit fram som en helt ny gren inom Software Engineering. Utvecklare av mobila applikationer står ständigt inför en utmaning när det gäller att välja vilket mobilt system man ska satsa på när man utvecklar applikationer. Valet av system kan vara helt avgörande för om man hittar rätt målgrupp av konsumenter och därmed kan generera tillräckligt med omsättning för att driva lönsam utveckling av applikationer. Det räcker inte att enbart kolla på vilket system som har mest användare eller vilket system som genererar mest omsättning, utan man bör noggrant överväga de förhållande som gäller för just den applikation som ska utvecklas.

BackgroundAnorexia nervosa is a growing problem in society and it is most common among women. It is a complex disease that affects both the mental and the physical health. The disease expresses itself differently from person to person, therefore, treatment should be individualized. Nurses need to gain insight into how patients feel about the treatment in order to understand their experience. Previous studies use statistical research to evaluate treatment.

To reconstruct a building is a long-term investment for farmers and it is important that people with different qualifications are involved at an early stage for making the system adapted to the animals as well the animal keeper. Therefore, ethologists who can contribute with their expertise are needed to design the system and get it to function well for the animals.A Swedish farmer who planned to rebuild her stall for tied dairy cattle to a loose-housing system for recruitment heifers for milk production asked me as an ethologist to find a system which can be fit to her existing tie-stall barn for 30 dairy cows, considering the animal needs in terms of movement, social interactions and play behaviors, and to theoretically compare the system with other systems with respect to the behaviors mentioned.The theoretical comparison between different systems was made through a scientific literature review.In agreement with the animal keeper I set out to fit a system with feeding cubicles, a system with cubicles and a system with deep straw bedding to the barn. After measurements were taken and preliminary drawings were outlined it was found that only the feeding cubicle system was possible to fit to the barn.The space provided will limit the animals to perform some playing behaviors. To decrease aggressive interactions between animals even thought a limiting area it is possible to provide partitions between resources animals compete around to prevent that more than one animal can get success to the resource at a particular place at one time. To increase the animal movement in the system the water trays were moved to the outer wall instead of kept in contact with the stalls.Although this report provides guidelines for rebuilding, other competences regarding building construction and a pre-test of the suggested building solution according to Swedish legislation are needed before the rebuilding can start.The results are directed mainly to the owner of the barn, but the literature review can be used by other cattle farmers and might bring increased understanding of the possible effects of different building solution on the animals..

Projektet omfattade en jämförelsestudie avseende stomsystem. Studien undersökte ramverk och fackverk/balk/pelar-system och genomfördes självständigt med stöttning av Ramböll AB´s kontor i Falun. Syftet var främst att undersöka vilka skillnader det finns mellan tvåledsramar och fackverk/balk/pelar-system för lätta hallbyggnader och försöka få klarhet i varför fackverk/balk/pelar-system är det dominerande systemet i Sverige eftersom övriga Europa har tagit en annan utveckling och domineras av tvåledsramar. Studien undersöker skillnaderna mellan systemen i en hallbyggnad med förutbestämda mått i stål.Inledningsvis gjordes en litteraturstudie för att få en bredare bakgrund av systemen och en bättre förståelse om förutsättningarna för varje system. Efter litteraturstudien kunde sedan ett typhus och beräkningsunderlag för jämförelsestudien tas fram.

The aim of this bachelor thesis is to examine the current situation as regarding the political equality in Iran. The method of this reaserch is based on a single-case studie wich grounds in secondary sources. The analysis of this paper is based on fields that concern political equality which in this study will focus on the right to vote, candidacies in the parliament election 2004 and the presidential election 2005. A democracy theory by Jack Lively is used to analyze the political equality in Iran´s political system.The Iranian regim is strongly criticized by the goverments in the Western world and NGO´s for the situation of the democracy and the human rights in the country. Despite the criticism, Iran still continues in the same political direction, although the democracy has gained a stronger role in the political sphere.

I denna studie undersöktes designöverväganden för ett VR-system som ska stödja en arkitektonisk designprocess. Dagens användning av VR-system inom arkitektur är inte särskilt utbredd men anses vara ett stort framtida användningsområde för VR-teknik. Större delen av den forsk-ning som bedrivs inom VR-området fokuserar på tekniken i sig. VR-system skapade i demonstrationssyfte används till att undersöka fenomen som avståndsbedömning och navigeringsförmåga i virtuella världar. Denna forskning är viktig, men är inte tillräcklig för att ge vägledning i hur man bör designa ett VR-system som ska stödja en arkitektonisk process.

Arlanda airport is Sweden?s largest airport. The demand for comfort cooling of the airport?s buildings is high and is mainly provided by district cooling. District cooling is based on the same principle as district heating.

In past decades information technology has changed the conditions of organizations, not at least within the industry. Advanced IT systems have become a fact in order to cope with rapid changes in the market and to effectively manage an organization?s knowledge. When organizations became more flexible and customized expectations from customers and stakeholders also become higher. These expectations and guidelines are documented in a company?s management system, which can be designed differently depending on what standards the company chooses to implement.

This essay investigates the feminist philosophy of Rosi Braidotti with particular focus on the alternative feminine feminist nomadic subject that she creates. I also introduce Braidotti?s theoretical inspiration from Gilles Deleuze and Luce Irigaray. I argue that Braidotti creates an alternative figuration for feminism through synthesizeing Deleuze?s concept of ?becoming? with Irigaray?s sexual difference-theory.

The mission was to create a prototype of a menu system for the companySystem Andersson AB. The instructions were that it has to be as interesting andmodern now as in 20 years. We had to look at technology from the cutting edgeof development to make our prototype survive in the future. WindowsPresentation Foundation (WPF) was the technique we focused on. There areonly a few applications that take advantage of WPF today, but it is predictedthat WPF will be the next generation method for developing applications to theWindows platform.To make our menu visually appealing, easy to use and at the same timefunctional, we followed the clear path and guidelines that are available ininteraction design.

This paper gives an introduction to the theory of minimal surfaces. It is in- tended for undergraduate students with some basic knowledge of differential geometry and complex analysis.After defining the concept of minimal surface and giving a brief histo- rical survey, we look at some well-known minimal surfaces and a few of their characteristic properties. The connection between minimal surfaces and harmonic functions is discussed and the Weierstrass-Enneper represen- tation formulas are introduced. We also present Bjo?rling?s problem and give some examples. .
