Kontrollmodul
This report describes the scientific work of designing and manufacturing an intelligent controller module prototype for automobile trailer connections. The functions of the module are both to drive the lamps and detect failures. The module also contains functions to handle other functions of the trailer. To learn about controller modules the group does extensive feasibility study.The group receives three already existing modules, the functions of the three modules are studied and tested in the lab, this is done too get a overview of the construction. The method used I called reversed engineering, a way of constructing by analyzing constructions already done.When the modules are analyzed, the functions of the prototype are tested and designed without copying the analyzed modules.
AUTOMATISK PAN/TILT-KONTROLLER FÖR ANTENNINRIKTNING
This report describes the design and construction of a prototype that automatically aims a microwave link towards a target. The link, that is located on a mobile aerial mast, is used by Saab Training Systems as a part of an infrastructure network. The report also discusses the development of a GUI that communicates with the control unit by Bluetooth.The control unit, called Pan/Tilt-controller, controls the position of the link by stepping motors. One motor controls the azimuth angle and the other one controls the elevation angle.By a GUI the operator enters the coordinates on its own position and the targets position. Hereafter a bearing is calculated and it will be sent up to the control unit.The control unit will sense its own direction by a magnetic sensor that works as an electronic compass.
Förändrad syn på svensk militär alliansfrihet? : En studie om svensk neutralitetspolitik mellan 1990-2008
Abstract: The purpose of this study is to examine how the Swedish policy of neutrality has changed between the years 1990-2008. The research method used for this essay has been comparative case study, which strives to answer four research questions. Two of these questions are: Which specific occurrences have been fundamental in changing the Swedish policy of neutrality? How have the Swedish policy of neutrality and the policy of non-alignment changed between the years 1990-2008? The theoretical frame work of this study consists of Europeanization as a comprehensive theoretical perspective. In order to explain the Swedish act regarding the policy of neutrality, Logic of Consequences and Logic of appropriateness are used.
En kvalitativ studie om svenska städers förväntningar och agerande i nätverket Eurotowns
Some researchers claim that we are witnessing the advancement of becoming a network society, and in spite of the different problems associated with the network form of organization, many cities still choose to engage in different types of networks. On account of that the aim of the study is to examine which expectations Swedish member cities of the network Eurotowns might have, and if their actions in the initial period of engagement in Eurotowns mainly could be explained by ?Logic of Consequentiality? or ?Logic of Appropriateness?.A qualitative research method was used and a major part of the empirical material consists of the information given by the interviewees.Regarding the expectations Swedish member cities have on Eurotowns, the result showed that five main areas could be identified mutual resource exchange, activities, breadth, security and meeting place. The results also showed that the actions of Swedish member cities may vary between ?Logic of Consequentiality?, ?Logic of Appropriateness? or a combination of the both logics.Furthermore the study also provides empirical evidence supporting the previously theoretical criticism expressed regarding the central assumption that the strategic actions of an actor can be regarded as a direct consequence of the mutual resource dependency..
Medialisera mera. En medielogisk thriller ? Kvantitativ innehållsanalys av partiledarutfrågningarna i P1/Ekot och P3/Valfestivalen år 2014
This study aims to map out the degree of mediatization present in the communication between Swedishpublic service journalists and politicians in the 2014 election campaign. In doing so we chose to look at thepresence of media logic in their communication with each other. Specifically, we have used the pre-electioninterviews with the party leaders from Sweden?s two biggest parties. Furthermore, we have chosen to focuson Sveriges Radio, the Swedish public service radio company.Sveriges Radio concists of four different radio channels, of which we have chosen to focus on the channelsP1 and P3, the first having a somewhat more ?serious? profile, focused on producing quality news and otherjournalistic products, while P3 is leaning towards a younger audience and describes its own work as ?soft,humorous and important radio?, mixed with music and other forms of entertainment.

Utveckling av programvara till ett inbyggt styrsystem
This thesis considers the development of the software for an, newly developed, embedded real-time control system, based on a Periferal Interface Controller (PIC). The control system is developed to be used for several different applications. In this thesis work, software for two different applications are developed. The first task is a time controlled system, while the other task is implementation of aPI-/PID-controller. A user interface is also developed and implemented.The time controlled system is an automatic horse feeder, which is used for feeding horses at certain predefined points in time.
Vem är controllern? : En kvalitativ studie om controllern i rollen som styrorienterad och traditionell ekonomichef
Sammanfattning Det finns många definitioner av vad yrket controller innebär, vilket visar att yrkestiteln är svårdefinierad. Syftet med studien är att beskriva controllerns arbetsroll i medelstora tillverkande privata företag och om controllerns roll fokuserar mer mot styrorienterade uppgifter eller mer mot traditionella ekonomiuppgifter. Vi utformade därför följande frågeställning: Är dagens controller i tillverkande företag mer styrorienterad eller mer en traditionell ekonomichef? Vi valde att genomföra en kvalitativ studie eftersom det möjliggör en djupare förståelse och sedan använde vi oss av en deduktiv ansats där vi gick från teori till empiri. I vår teoretiska referensram har vi beskrivit olika egenskaper, färdigheter, roller och arbetssätt som ingår i controllerns yrke.
Vetenskap och makt. En analys av två vetenskapliga paradigms skilda maktlogiker.
This essay analyse the relationships between scientific paradigms and different logics of power in the field of psychiatry, primarily in the fields of attention disorders of children and schizophrenia. In these two fields of psychiatric research and treatment, there exist two scientific paradigms, a biological/neuropsychiatric and a socialpsychological, working from different standpoints regarding questions of ontology, epistemology and theories of value. Drawing from Thomas Kuhns paradigmatic theory of science, and Michel Foucaults concept of power, this essay proposes that different paradigmatic standpoints gives rise to different logics of power. Relying on the concept of power/knowledge and different paradigmatic standpoints, the essay states that the biological/neuropsychiatric paradigm produces a biological individualising logic of power that fixes the individual to his/hers biological condition. This in contrast to the socialpsychological paradigm, which on the basis of its paradigmatic standpoints produces a social-group related logic of power.
Kombinerad DSP- och FPGA-lösning för en bildbehandlingsapplikation
This Master's Thesis describes the design of a new system where a digital signal processor has been added to an existing imaging system consisting of field programmable gate arrays. The new system will offer a higher degree of flexibility by considerably shortening the design time and make it possible to implement more complex algorithms than the existing ones. The choice of system architecture and a test implementation are discussed. The test implementation consists of a program for the digital signal processor and VHDL code for one of the field programmable gate arrays. The code for the digital signal processor was designed for testing on an evaluation board from Texas Instruments.
Wittgenstein och skepticismen
In his book Wittgenstein on Rules and Private Language (1982) Saul Kripke claims that Wittgenstein argues for a certain form of scepticism in his book Philosophical Investigations (1953), namely a new form of philosophical scepticism, a result of Wittgenstein´s idea of language as language games. Nihilism, scepticism of meaning or of concept, constitutive scepticism are other commentators´ different names of the same phenomenon. The philosophy of Wittgenstein accounts for how our words, including the words of mathematics, have no meaning and there are no a priori justified objective facts as to what I mean about a word. We follow the rules blindly and without justification. We are unable to find any facts against this proposal.
Ekonomistyrning, på liv eller död? : En kvalitativ studie om controllers användning av styrmedel inom sjukvården.
Bakgrund: Sjukvården beskrivs som oerhört komplex och genom bland annat utveckling av ny och dyr teknik, som i sin tur genererar bättre vård, gör det svårt för sjukhus att hålla sin budget. En controller har en fundamental roll i en organisations ekonomistyrning och ska med hjälp av diverse styrmedel styra och kontrollera så att verksamheten drivs mot ekonomiska mål.Syfte: Syftet med uppsatsen var att beskriva och analysera hur en controller inom sjukvården använder ekonomiska styrmedel för att nå ekonomisk måluppfyllelse samt skapa en förståelse för hur en controller hanterar balansgången mellan ekonomisk måluppfyllelse och vårdkvalité.Metod: Uppsatsen är formad med en kvalitativ forskningsdesign. En flerfallstudie har använts som forskningsstrategi där den empiriska datan är insamlad genom ostrukturerade intervjuer med anställda vid två sjukhus i Småland, länssjukhuset i Kalmar och centrallasarettet i Växjö. Det teoretiska avsnittet är byggt med data som insamlats från litteratur och vetenskapliga artiklar som varit tillgängliga via Linnéuniversitetets bibliotekskatalog.Slutsats: De resultat som framkommer av studien påvisar att en controllerns användning av styrmedel tenderar att fokusera på ekonomisk måluppfyllelse. Genom användning i större utsträckning av de styrmedel som är under utveckling finns möjligheter för controllern att även påverka vårdkvalité..
Hållbarhetsidéns resa : En fallstudie om hur hållbarhetsidén översätts inom ett pappersbruk
This study focuses on how the idea of sustainability is dealt with by companies, how the idea changes when moving through a company structure and how the different individuals interpret the idea. To date, many different studies have been written on the subject of sustainability, but few share the perspective addressed in this particular study. This case study was formed at a paper mill in the central part of Sweden. Semi-structured interviews with employees working on different hierarchical levels, within the same company, were chosen in order to get an insight into how the idea of sustainability is implemented throughout an entire company. The interviews have been transcribed to help identify contrasting patterns.This study has shown that the idea of sustainability, and its context within society, differs from how the idea is perceived in the organization.
