In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.

AbstractOur world is facing new challenges depending on the climate changes. The UN panel of climate changes has determined that the human race is responsible for the changes, but also that we have the opportunity to reduce the effects. This demands that the information reaches out to the public which means that the school system carries major responsibility to this type of questions. This also means that the teachers have to be observant, and give the questions the attention which is needed. The purpose of this essay is to see if this awareness exists today among active teachers and teacher students and if the perspective differs among them, but also their opinions is in agreement with the course plan in the subject.

Language impairment affects the ability to communicate. Children with languageimpairment have difficulties in using language in interaction to various degrees, and the contributions of the conversational partner are of great importance. The use of languagein interaction can be analysed by means of conversation analysis. The purpose of thepresent study was to study interaction of a group of pre-school children with language impairment with four different conversational partners. These were a peer with languag eimpairment, a peer with typical language development, a pre-school teacher and a parent.

The purpose of this paper is to test a procedure that would be useful for a certain, more final purpose. Assume that you want to know if the differences in the result of a certain effort in health care have any connection with differences between the life situations of the patients. This would be easier to investigate if the life situations of the patients had connection to the easily available variable Health Care Cost (in Swedish VK). In that case the searching for connections between VK of patient groups and the result of health care efforts would be sufficient to gain knowledge of possible connection between health care efforts and life situations. Thus that is the final purpose.

The aim of this study has been to examine six books about Oscar Wilde?s homosexuality during the years 1906 ? 2003. I have been analyzing their descriptions about his sexual orientation and compared them to each other to see the changes through time. In order to see some clear changes the main focus was to choose time differences between the books. It was clear that the earlier writers had negative opinions and thoughts about his sexual deviation the way they described it.

This thesis examines the possible beneficial effects of a temporary cooperation between a national brand and a private brand. The main hypothesis suggests that if a national brand wants to make a category extension to a remote product category, it should be able to decrease its risk by affiliating itself with a private brand. The national brand should through such a brand alliance be able to borrow some of the flexible characteristics that a private brand possesses to increase its associations with the new category. The survey consisted of 800 questionnaires with different cooperations between a private brand (ICA) and two national brands (Tropicana and Bravo). These were handed out to students in the universities of Stockholm.

The decisions for investment are forward-looking and the base of a long-term strategy. The research within investment have focused on diverse formulas which are used in financial assessment, which also should be complemented with qualitative evaluation. Consequently, the focus should not only be on the execution of the formulas. Less time have been spent on research concerning what actually initiates the investment proposals and affects the decision-making. This will be highlighted in this essay.

Pyometra, chronic purulent metritis in metoestrus, is a common disease in intact bitches. About 25% of all bitches in Sweden have contracted the disease before ten years of age. Clinical signs of the disease are varied, and the course may be either slow or acute. The diagnosis is most commonly made by radiographical or ultrasonographical examination of the abdomen in combination with blood biochemical and hematological analyses. The safest and most efficient treatment of pyometra is surgical ovariohysterectomy.There is room for improvement of both diagnostic tools and possible prognostic indicators for pyometra.Mast cells are large leucocytes, with granule that contain inflammatory mediators.

This thesis describes the developmentof a device called "Oil Separator"which is used for washing vehicles andparticularly car washing. The devicedeveloped for Mr. Car Bilvård AB inUppsala, the company's work involvespassenger transport and courierservices. The company needs anexternal device that meets theenvironmental standards to wash theirown cars in the premises without theneed to modify or reconstruct on thepremises ground as the premises is ona leased contract.Work began with a preliminary study onthe literatures that describes boththe function and structure ofdesigning the device. A few interviewswith other car wash companies had beenimplemented, and some measurements.After collection of the necessaryinformation the specifications ofcustomer requirement was presented .With these requirements a fewconcepts was generated and weighedusing the Pugh matrix for conceptsselection for further development.The final concept was furtherdeveloped and a design has beenpresented.

The aim of this thesis is to compare two different classification schemes with each other and see what the differences and similarities are when classifying literature concerning film and television. One of the schemes is of general kind, Klassifikationssystem för svenska bibliotek (SAB) and the other is a special system, FIAF Classification scheme for literature on film and television. The focus of the examination is on comparing the structure, contents and division of firstly the main classes and secondly on comparing the notation and the auxiliary tables in the schemes. The theoretical framework of the comparison is based upon theory of classification but the conclusions drawn are though mostly of a more subjective character. In addition to the comparison itself interviews have been made with four libraries, two with experiences of SAB and two with experiences of FIAF.

This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.

Abstract Abstract The aim of this essay was to investigate the level of the organizational state of readiness for receiving students with learning disabilities in classes specialized in working with students recently arrived in Sweden, called förberedelseklasser, which could be translated as preparational classes. I tried to do so by answering two questions: *What routines do principals believe that the particular School has for dealing with cases in which a student in a preparational class is suspected to have some form of learning disability? *What perception do teachers have in regards to whether or not the system at their School is well prepared for discovering and aiding students in preparational classes suspected to have learning disabilities? The first question was directed to principals currently working in schools where a large part of the students are bilingual, and many of those recently arrived in Sweden. The second question was aimed at teachers that work in preparational classes. By interviewing two principals and three teachers I came to the conclusion that the teachers believe that their students are often misplaced in preparational classes when in deed they should be placed in a special educations group. My essay also shows that both principals and teachers are dissatisfied with the amount of time the process of discovering, investigating and diagnosing a student with learning disabilities takes.

Ett rörelsehinder inskränker inte bara det funktionshindrade barnets fysiska möjligheter utan kan verka handikappande även på social nivå. Dans är ett ämne i skolan där man interagerar och får möjlighet att samarbeta och utvecklas socialt. Frågeställningen som denna uppsats undersöker lyder: Vilken betydelse kan dans i skolan ha för rörelsehindrade elevers mentala utveckling?Frågan besvaras dels av berörd litteratur, dels av intervjurespondenter.Det framgår att dans, som fokuserar på den funktionella kroppen, har förmåga att få de rörelsehindrade ungdomarna att se vad de har möjlighet att åstadkomma i stället för att lägga fokus på funktionsnedsättningen. Det framkommer också att de kan dansa med icke-rörelsehindrade elever och ta del av den sociala gemenskapen samt att inlärningsförmågan och kunskapsnivån höjs.

This paper deals with prehistoric charred organic material, interpreted as bread, found in graves and in the underlying settlement at Kalvshälla, Järfälla parish in Uppland. The aim was to categorize the organic material morphologically and with the help of Fourier transformed Infrared spectroscopy (FT-IR) to see whether it was bread or not. Material from 13 graves (dated to Late Roman Iron Age until Viking Age) and 3 finds from the settlement have been analysed. Differences were noted both in shape, porosity and structure. Some of the material has been interpreted as cereal based foodstuff instead of bread due to morphological discrepancies.
