Styrsystem : För en forskningsutrustning
The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.Design and manufacturing of the equipment was handled internally at LIU.The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them.
Unesco, Malraux och ombildningens museum : Estetik och kosmopolitik i efterkrigstid
An inquiry into the post-war European aesthetic and political landscape should take the international organization Unesco?s colour reproductions and travelling exhibitions of paintings into consideration. In these, the organization implements André Malraux? idea of the ?imaginary museum? as a framework for a future cosmopolitical, aesthetic (and utopian) community. During the late 1940?s, the Swedish government also discusses the need for raising an ?aesthetic awareness? amongst their citizens as a consequence to a poor knowledge in the fine arts.
Mätutrustning för kosmisk strålning
The purpose with this examination is to build a measureequipment to AerotechTelub AB (AT), who will registrate fault in SRAM-memory in contact with cosmic radiation. The equipment will be created around developcard from Memec Design with FPGA from Xilinx. The logic in the FPGA will be implemented with the hardwaredescribed language VHDL. The SRAM-memory that will be tested is build in CMOS-teknologi. The memorycells will be loaded with a predecided bitpattern.
Vad är en framgångsrik kampanj? : En studie av branschens syn på PR- och reklamkampanjers effekter
This qualitative study examines how emergency people are framed in Swedish evening-, and local newspapers during the forest fire in Va?stmanland, Sweden 2014. The study also includes if there is any difference between the framing due to the location of the newspaper. The study is based on qualitative text analysis. The theoretical basis is representation, framing theory, media image, media logic and a few conceptions from crisis communication theory.

Optimering av testning av säkerhetskritiska funktioner
Inom industrin används olika testmetoder för att uppnå hög kvalitet i mjukvarukontrollerade system. Kvalitetskraven är särskilt höga för säkerhetskritiska system t.ex. styr- och reglersystem i fordon. I det här examensarbetet används två analysmetoder (Fault Mode and Effects Analysis och Fault Tree Analysis) för att ta fram ett nytt säkerhetstest för ett broms- och växlingssystem som Scania tillverkar. Det studeras även hur formella metoder kan användas för att ytterligare öka kvalitet ochh tillförlitlighet.

Att skriva en poplåt : vägen från en enkel idé till färdig låt
Detta projekt har handlat om att komponera elektronisk popmusik med hjälp av digitalaverktyg. Jag ville undersöka hur användandet av digitala verktyg påverkar enskompositionsprocess. Målet var att skriva två låtar innehållande både text och musik.Metoden jag använt är att jag först improviserat fram melodifragment som jag sedan spelat ini inspelningsprogrammet Logic Pro. I programmet har jag sedan spelat in flera spår för attbygga upp harmonier och rytmik kring melodierna. Arbetet har resulterat i en färdig låt sominnehåller både text och musik och en låt som endast innehåller musik..

?Kvinnan föder grensle över en grav? : En studie av det groteska i Samuel Becketts I väntan på Godot
This essay examines the grotesque in Samuel Becketts wellknown play Waiting for Godot. The play is primarily seen as an icon of absurdism, and it is such not appropriate to examine the play as if it belongs to the litterary genre of grotesque. The primary purpose of absurdism is to reveal the pointless- and emptiness of existence. In order to illustrate these points absurdism will often make use of the common characteristics of the grotesque. With this in mind I present, within this essay, an eximination of whether Samuel Becket makes use of these characteristics to assist his portayal of emptiness in Waiting for Godot.A prior understanding of absurdism is required and i have as such primarly used Martin Esslins famous studies.The studies of the grotesque are mainly represented by two theorists.
Textens spegel till Narcissus´minne : Ett betraktande av den egna skrivprocessen
In this essay I analyse three of my own texts included in an unpublished collection entitled till Narcissus' minne. Genres are discussed and a detailed study of how the writing process has progressed is done. The essay does not follow any specific literary or scholarly method of analysis, but to some extent the sphere of interpretation is explored. By associative interpretation the special logic of dreaming, the activity of the unconsciousness and the expansive accessibility of the memories, which characterize the texts, is traced. These structural features open a link to the way of psychoanalytical interpretation, but the essay does not strive for a complete account.
Logikbaserade dokumentåtervinningsmodeller
The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.
Ultraljudsmätare för bubbelfälla
This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.
