Prototyputveckling av digitalt styrsystem för torkskåp
Nimo Verken AB is the leading producer in the Scandinavia of drying cabinets. The construction has, with small changes, been the same since the 70s with a thermostat and a timer as controlling system. There was a wish to develop a modern cabinet which showed remaining time on a display and with energy saving functions.In this report we go through how it is possible to implement a digital controlling system, where remaining time is shown on a display and where it is possible to choose a preset ?program?.The report first presents the fundamental theory for a PIC, where we describe the different registers, how interrupts are handled, the internal clock function and how data is sent to control the different parts of the construction.Next the report presents and describes the new hardware that is needed, such as the encoder, the temperature sensor and the display.After the theory we describe how the program in the PIC may be drafted. Last in the report we have the result of the tests of the temperature variations and the accuracy of the time..
Energieffektivisering av färskvattensystemet på Skärblacka pappersbruk
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.
HDR och Tone mapping i automatiserade tullsystem
This report is about how HDR (HighDynamicRange) can be created and used in combination with Tone mapping. This work has been carried out together with Kapsch TrafficCom AB in Jönköping.The objective of this project is to:Evaluate and investigate the effects given to pictures by HDR and tone mapping.Evaluate if the technology may lead to improvements in Kapsch?s systems.To construct a program which is able to handle some form of tone mapping or HDR-algorithm.These questions will be answered in this report:What kind of effects has HDR and tone mapping-algorithms on pictures?Can the HDR-technology give better data in Kapsch?s systems?The research method used in this report is called action research. This means the authors has investigated the technology by reading different documentations and by testing different algorithms to see what kind of result they give. The report describes some of the tests made to see if the technology is appropriate in Kapsch?s system.There is two smaller reports made by the authors which documenting some of the work.The first report describes the work with different settings for a camera to create pictures with HDR-quality.
Könsmärkning och statusrelevans i folkbiblioteksvärlden
The main purpose of this Masters thesis is to examine gender division in public libraries by reviewing literature and interviewing eight public librarians and two chief librarians. The reason why we decided to investigate this topic is the lack of research concerning sex-segregation in library and information science. By choosing this subject we intend to deepen the understanding of the significance of gender both within the public library and of the occupation in general. Some researchers claim that the low status of librarianship is a result of the large proportion of women in the profession. We want to find out how our informants view the relation between professional status and female domination.
Skolan som institution : En processtudie av skolpolitikens skeenden
This thesis has aimed to study steering process and institutionalization in the context of educational policy work. This has been conducted by using empirical material from the political decision-making process that preceded the implementation of a new national program on how principals should be educated and certified. By using an aggregated theoretical point of view containing new institutionalism and traditional Swedish curriculum theory, the process was analyzed from different perspectives. The results depict a process that contained several actors who tried to shape the principal education program differently. From the theoretical perspectives, the decision-making process could be understood as an act of both self-interest as well as trust in their own beliefs and cultural values.
Emfio : Enhetliga mallar för IT-forensiska operationer
Polisens it-forensiska avdelning har bl.a. i uppgift att säkra bevis från datorer som tillhör personer misstänkta för brott. Det polisen gör är att använda en mängd olika program som producerar loggar med webbhistorik, e-post och meddelanden från en mängd program som används vid chatt. Det den här rapporten kommer fokusera på är framtagningen av en applikation som kan ta in alla dessa typer av loggar och rensa bort onödig information. Den återstående informationen struktureras om för att kunna generera en rapport med enhetligt utseende.
System 348 - Rekombinator : Analys av reglerproblematik vid O2
In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.
Pedagogisk utformning av ANT-programmet ?Steg-för-Steg?
Abstrakt
Syfte: Syftet med denna studie är att öka förståelsen för ANT-programmet
Steg-för-Stegs pedagogiska upplägg. Genom att:
? Analysera programmets pedagogiska utformning
? Studera några ledares syn på det pedagogiska upplägget.
Metod: Denna uppsats är grundad i en hermeneutisk ansats eftersom intresset
var att studera innebörden och dess betydelse och därigenom finna förståelse.
Texttolkning av programmets kursmaterial har använts för att kunna se vilken
pedagogisk utformning programmet har och intervjuer har använts för att få
kunskaper i tre ledares syn på programmets upplägg.
Resultat: Sammanfattningsvis visar resultatet att det finns två pedagogiska
utformningar på Steg-för-Steg program.
Matematik - för skolan eller livet? : En studie om hur Matematik A anpassas till olika gymnasieprogram
Matematikundervisningen på gymnasiet ska ge eleverna kunskaper för vardagsliv och en grund för kommande arbetsliv. Lärare på en gymnasieskola har intervjuats om hur de anpassar Matematik A till olika program och vilken respons de upplever från eleverna på dessa anpassningar. Denna studie med kvalitativ ansats har utifrån intervjuerna gett en kartläggning av hur lärare anpassar undervisningen av Matematik A för olika program, både medvetet och omedvetet. Utifrån kartläggningen gjordes också en fördjupad analys för att hitta troliga bakomliggande faktorer till anpassningarna. Resultatet visar att lärarna anpassar matematiken till olika program på flera sätt och nivåer. Vissa anpassningar gör lärarna medvetet, som att vinkla uppgifter, aktiviteter och genomgångar till grupper och programmål eller på individnivå med stöd, extra material och utmaningar.

En utvärdering av två pearl growing-metoder i ISI Web of Science
The purpose of this thesis is to evaluate two pearl growing methods in ISI Web of Science. The methods tested are Find Related Records FRR, an automatic service that uses bibliographic coupling, and Author Keywords AK, where searches are performed using the two first keywords from this field. Both search methods were used on twenty initial documents and the first twenty hits were evaluated for relevance using a binary scale 0,1. The relevance criteria were based on specific information needs connected to every initial document. The measures used to evaluate the effectiveness of the search methods were Precision at DCV=10, P10, and Uninterpolated Average Precision AP.
Blinkbeteendebaserad trötthetsdetektering : metodutveckling och validering
Electrooculogram (EOG) data was used to develop, adjust and validate a method for drowsiness detection in drivers. The drowsiness detection was based on changes in blink behaviour and classification was made on a four graded scale. The purpose was to detect early signs of drowsiness in order to warn a driver. MATLAB was used for implementation. For adjustment and validatation, two different reference measures were used; driver reported ratings of drowsiness and an electroencephalogram (EEG) based scoring scale.
