Slutfasstyrning av missil med explicit prediktionsreglering

Arbetet har utförts på Saab Bofors Dynamics AB i Linköping och dess syfte är att undersöka möjligheten att applicera teorin för prediktionsreglering, Model Predictive Control (MPC), på guidance systemet i en missil av typen Medium Range Air-to-Air Missiles (MRAAM). Även implementering via Explicit MPC har undersökts. I tidigare studier har det visat sig att den moderna slutfasstyrningsalgoritmen Linear Quadratic Augmented Proportional Navigation (LQAPN), som återkopplar missilens acceleration och rotation, uppvisar en bättre prestanda än de mer klassiska styrlagarna. Det främsta intresset med denna studie är därför att undersöka hur tillvida en styrlag baserad på MPC kan mäata sig med dessa resultat. Fördelen med att använda MPC är framförallt att man kan ta hänsyn till styrsignalbegränsningar på ett direkt och intuitivt sätt.

Colombianer på bioduken : Representationen av tre Hollywoodproducerade actionfilmer

The purpose of the thesis was to analyse three action films; Collateral Damage from 2002; Clear and Present Danger from 1994; and Scarface from 1983, in order to see how Colombians are represented in these movies.The action genre comprises of different stereotypes where the hero and the villain are represented in conjunction to each other. The analysis is about the way the films content and form are used to uphold the representation of Colombians, but also the villain and the hero more generally.Critical Discourse Analysis was used, as main method, and the concepts of denotation and connotation guided the analysis. The main conclusion is that the three movies reproduced an already established collective stereotype of Latin Americans, stereotype that includes both Colombia and Colombians..

"Warden och den irreguljära konflikten" : Har Wardens teorier spelat ut sin roll?

Johan A. Warden tog fram sin modell om motståndaren som ett system för att genom denna hitta dess svagheter. Modellen visade sig vara mycket användbar inom mellanstatliga konflikter och var mycket effektiv vid planerandet och genomförandet av USA:s offensiv mot Irak under inledningen av Gulfkriget. Men kopplat mot irreguljära konflikter har Wardens modell stött på mycket kritik då den anses spelat ut sin roll och därför inte längre kan anses applicerbar vid planerandet av luftoperationer inom denna typ av krigföring. Denna uppsats skall se om det är precisionsvapen och användandet av dessa som räddar kvar Warden inom planeringen av luftoperationer inom irreguljär krigföring..

Vad får det lov att vara: en bok eller ett tv-spel? En studie om folkbibliotekens inköp av medier.

The purpose of this Master`s thesis is to examine if the pur-chase of media in public libraries reflects the library's role in society. Two questions have been posed: ? What view of public library's role in society is reflected in the purchase of media? ? What principles guide the selection of media in public li-braries in Sweden? In order to investigate these questions, we used a question-naire that we sent out to a sample of 120 public libraries in Sweden. The analysis is based on a theory of three ap-proaches to the role of the library developed by Douglas Raber. The three approaches are the conservative approach, the populist approach and the social approach.

It brings higher costs, a more stressful work climate and holds back the company from becoming more efficient.Field studies will be conducted on the changeover, which will be observed and filmed.

Att göra tillit : Hur tillit skapas i interaktionen mellan människor

The purpose of this essay is to examine the origin of generalized trust. We compare existing theories on trust to determine what approach is more fruitful in explaining the prevalence, or absence, of trust. Our conviction is that trust should be viewed as an interaction, rather than a disposition or a rational choice. The sample is based on the countries of the OECD. In total, five different hypotheses are tested: i) that generalized trust is created by equal distribution of income, ii) that generalized trust is created through monitoring of the state, iii) that generalized trust is created through rule by law; iv) that generalized trust is created when the welfare apparatus is guided by principles of universalism; or iv) that generalized trust is created when the state integrates trust networks.

Inventering av processvattenbalans : fastställande av fjärrvärmedistributionens läckage inom Vattenfall Värme Uppsala AB

Heat is distributed to the district heating customers through pipes with water as a heat carrier. The district heating system is complex. To decide what is leakages from the district heating net versus what is the water consumption of the plant, is difficult. Therefore, the purpose of this master thesis is to establish a model where the district heating net?s leakages but also the water consumption of the plant can be followed daily. The project is performed at Vattenfall´s district heating power plant in Uppsala. Information is gathered through discussions, drawings of the plant and guided tours of the plant.

Sexuell perversion eller moralisk progresion? : En idéhistorisk studie i hur 1960-talets sexualpolitiska debatt manifesterade de sexuella avvikarnas beskaffenheter, och hur dessa perspektiv sedan avspeglade sig i SOU 1976:9.

The main purpose with this essay is to evaluate how the characters of the sexually deviated was discussed during the sexual political debate in the 1960s, and if those apprehensions were reflected in SOU 1976:9 concerning sexual abuse. Furthermore, my prime intention will be to compare the reconstructed historical context, alias the sexual political debate, with the analyzed document, with the purpose to explicate why the anticipated political action weren?t sanctioned and implemented by the parliament. The analysis is carried out through a methodology that retrieves its primal premises from Quentin Skinners theories regarding the history of ideas. My most essential conclusions would be that there in fact existed an equivalence regarding the ideological framework between the radical axioms that was conceived during the sexual political debate and the stipulations that was formulated in the document.

Allt som är fast förflyktigas : Föreställningar om arbete och sambandet mellan arbete, tillväxt och välfärd i senmodernitetens Sverige

The focus of this thesis is the conception of work and the relation between work, economic growth and welfare in today?s Sweden in the editorial of Dagens Nyheter (DN), which is the main morning paper in Sweden.As the theoretical foundation of this thesis is social constructionism and the method being used is critical discourse analysis, the language is considered as an important source for the construction of value and meaning of work. In that context it is important to investigate how DN, by certain ways of representing reality, preserves a certain view of the human being, the society and the economy. Which ideological ideas underlie the conception of work that emerges in DN? What social consequences will these ideas have?The thesis discusses the ?truths? that the editorialists mediate concerning for example the view of the human being as guided by rational choice and the view of economic growth as the main goal for social life.One of the conclusions is that DN considers work as a means for economic growth as economic growth is regarded fundamental for the survival of the welfare state..

Styrkortstillämpning i två kommunala förvaltningar : hur en lokal kommunal kontext påverkar och påverkas av en styrmodell

A variety of studies have been conducted on the use of the balanced scorecard in the public sector. Fewer studies, however, is made at a lower, more local level within municipal departments. The aim is to describe the scorecard application by two different departments, while scorecard adjustment over time and actors and their rules are addressed in this context. This has led us to the following problem: How can scorecard application be described in two different departments in a municipal context? In the theoretical framework we presented fundamental theories of balanced scorecard in different contexts, a scorecards translation process and the rules that guide and limit the actors in the organization.

Konstf?rst?relse/F?rst?relsekonster: En unders?kning av konstruktiv ikonoklasm som konstn?rlig process

Building on the concept of constructive iconoclasm as a creational force of iconicity, this thesis examines how the contemporary iconoclastic discourse is related to artistic process. Studies have shown that the performative act of destroying art that is an historical phenomenon is highly present within the contemporary art discourse today. Due to the many dimensions of contemporary art, the ways in which iconoclastic deeds appear may differ from the historical narrative. While iconoclasm and iconicity are being reciprocal processes that can only exist in relation to each other and their context, there are signs that the destructive act itself is being recontextualized by contemporary artists. Guided by the framework of Norman Fairclough?s critical discourse analysis, the thesis examines the processes of conceptual and constructive art destruction by analyzing the discourses of two case studies situated in the contemporary art market.
