Missilstyrning med Model Predictive Control

This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.

Vem bryr sig? : Ett kommunikativt perspektiv på fusionen mellan Växjö Universitet och Högskolan i Kalmar

This essay takes the three models from Allison and Zelikow book Essence of decision and applies them on the Swedish defense system. After the cold war the Swedish defense system had to undergo changes to be a more modern defense and be able to defend Sweden against threats. To also be able to cooperate with other countries in peacekeeping operations the Swedish defense had to be reorganized. The solution was to change direction from a defense system that was organized for invasion to instead be a movable defense ready for any challenge in Sweden or abroad. This reorganization will be analyzed according to the three different models..

Optimering av slutfasstyrning

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.

Fred och säkerhet? : En studie om det Svenska Försvaret utifrån tre perspektiv, Bonsdorff, Andrén och Clausewitz

Following an increase in hostile foreign activity. The discussion regarding Sweden?s defense force´s ability to perform its task has come to a new heading. With the end of the cold war as a major revolution in matters of international security, a major overhaul has taken place to transform the static total defense plan of the nation to a less rigid operational system.Following an analysis of the budgets total amount from the governments of 2002 until 2015 it is clear that while the amount of resources has never directly been lowered, it has shrunk in relation to the countries total GDP. The possible futures for the defense of Sweden bring three possibilities forward in correlation three unique perspectives on military and political policy.Out of the three possibilities the focus on military strength as a political resource seems to be garnering the most support with the latest incursions made my foreign submersibles and the ever growing presence of 5th generation of warfare.

Försvaret i skolan : En studie om total- och civilförsvarundervisning i skolan under 70-talets kallakrigsår.

The purpose of this essay is to illustrate the preparation of total and civil defense education in schools in the 1970s to gain insight into how the school looked and pondered the complicated world that existed outside the school's doors. By using the concepts of welfare state, welfare and civil defense culture, I have studied relevant materials to get answers to questions treating the total and civil education in schools after Lgr69, the way the state sees the subject and if it is possible to detect a civil defense culture in schools and if so, how it will be expressed.     The results show that the state emphasized education as incredibly important because knowledge of how to act in a crisis or war could be extremely crucial for the individuals and their survival. The education was so important that it got a role as a main factor in Lgr69. But even if the education was important the teachers had huge problems with the schedule and many teachers couldn´t educate all facts because they didn´t have enough time.

Anledningar till staters anskaffande och behållande av kärnvapen och faktorer som påverkar staters kärnvapenpolitik

The purpose of this thesis is to explain why states obtain nuclear weapons and the role variousactors and interests play in the making of states´ nuclear policies. The main questions are asfollows: (1) What big theories exist concerning states obtaining nuclear weapon and nucleararmament in International Relations and what relevance do they have of the post cold-war period?,(2) What is the meaning of the perspective of the Military-Industrial Complex (MIC)?, and (3)Arethere empirical studies which supports the existence of a MIC in the United States?The focus lies on actors and driving forces that are internal to states and it is also important toinvestigate if the theories have relevance for the post 9/11-era. The study uses the method ofqualitative literature-study with some quantitative segments. It is claimed that states might beinterested in justifying their behaviour in a morally appealing way and that real reasons may behidden.

Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

Was the parliament united in the two decisions and if they were not, why? 3.

Militär alliansfrihet eller inte? : En argumentationsanalys av Moderaterna respektive Socialdemokraternas syn på ett svenskt medlemskap i försvarsalliansen Nato

The purpose with this study is to investigate how the two biggest political parties, the Social Democrats and the Moderate/Conservative Party, looks at a membership in the defense alliance North Atlantic Treaty Organization. The question have the illegal annexation of Crimea affected how the parties look at a membership in Nato will be answered and analyzed. How they discuss, how they believe that a membership can affect the Swedish foreign policy will be examined in this paper. Nato is a topic that during the last century?s have divided the Swedish population into two groups: one that advocates a membership and one that fight?s against a Swedish membership in the alliance. The debate about Nato has, since the illegal annexation of the Crimea, changed and are now more relevant than ever to discuss.

Försvarsstrategier och strategisk trovärdighet vid fientliga övertagningsförsök - En fallstudie av Scania och Skandia

Background: Mergers and acquisitions have evolved from initially almost exclusively having been an American phenomenon, to becoming a common occurrence throughout the world. Companies though, are not defenseless against hostile bids, but must take many factors into account when selecting defense measures. Purpose: This paper aims to enhance the understanding of acquisitions through hostile bids on the companies studied. More specifically, this study aims to create a deeper understanding in how Scania and Skandia have chosen their defense measures, or could have chosen, before and during their hostile bidding processes with specific concern for their strategic credibility. Method: This paper is based on two companies listed on the Stockholm Stock Exchange exposed to hostile takeover attempts in a similar time period.

MISSILE : Utvecklingsmodell och strategier för framgångsrika publika webbtjänster

Att utveckla en publik webbtjänst kan tyckas lätt, men att få denna till en framgångsrik och lönsam applikation är en annan sak. Konkurrensen är idag stenhård och en bra applikation är långt ifrån det enda man behöver för att lyckas.Studiens syfte var att kartlägga och öka förståelsen kring publik webbtjänstutveckling, ett område som tidigare inte fått så stor uppmärksamhet i den akademiska världen. Studien bygger på ett empiriskt material insamlat genom intervjuer med några av Sveriges främsta IT-entreprenörer inom området. Studien inkluderade även ett praktiskt moment där utveckling av inbjudningssajten InviClub.se genomförts för att praktiskt testa teorierna.Vår studie visade på att traditionella systemutvecklingsmetoder är svåra att tillämpa på detta område. En faktor som visade sig vara av yttersta vikt för lyckade projekt var snabbhet, något som de traditionella modellerna RUP och Vattenfallsmodellen inte prioriterar.

Kubakrisen : En tidningsstudie om svenska morgontidningars rapportering kring krisen

AbstractKubakrisen; En tidningsstudie om svenska morgontidningars rapportering kring krisen The Cuban Missile Crisis; A media study of Swedish morning papers reporting about the crisis The purpose of the survey is to illustrate how four Swedish newspapers, Svenska Dagbladet, Göteborgs Handels- och Sjöfartstidning, Dagen and Ny Dag reports about the Cuban missile crisis based on the questions. The survey highlights what distinguishes the morning papers and by how they take the position of the ship blockade against Cuba that United States issued and what position they take on who to blame in the conflict, but also how leaders Khrushchev, Kennedy and Castro portrayed. The study is based on the basis of a newspaper study and theory of priming serves as an instrument for the collection of materials. The survey results show in the first issue of how the papers stand to US ship blockade, which SvD endorses, while GHT and Ny Dag condemns it and Dagen stand in the middle without any real position. Previous studies treated SvD stance during the Cold War, shows that during the Vietnam War in 1965 SvD was very critical of the USA and their involvement. In this study, regarding the Cuban missile crisis, SvD are most clearly pro-US while Ny Dag accuse and highlights strong criticism of the United States. As for Chrusjtjov, Kennedy and Castro, the survey shows that three out of four newspapers writes about a surprised Chrusjtjov, who had gone too far and a Kennedy who are determined and implacable.
