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.

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.

Förälder på olika villkor : En studie av kriminalvårdensarbete med frihetsberövade föräldrar

It is a qualitative study and two interviews have been done with employees from a prison for women and one interview from a prison for men. Two interviews have been done with two former incarcerated parents, one mother and one father. One interview has also been done with an organization which gives children with incarcerated parents support and an opportunity to meet other children in the same situation.

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.

Robotsystem 15:s påverkan på den svenska ytstridstaktiken

Sveriges ytstridskrafter hade länge en förmåga att hävda sig mot fiendens stridskrafter ute till havs på 1950- och 60-talen. Nedrustningsprogrammet av försvaret på 1960-talet innebar att teknikutvecklingen bromsade upp och flottans större fartyg kryssare, fregatter och jagare skulle bytas ut till en lätt flotta med små snabba enheter. Detta resulterade i att flottans taktik anpassades till ett tillbakadraget uppträdande längs med kustbandet och inom skärgården. Svenska officerare bevittnade på när Sovjetunionen rustade upp och utvecklade nya vapen och fartyg med robotar av högsta kvalité i Östersjöområdet. Detta hot medförde att officerarna i flottan ville satsa på ett långräckviddigt vapen för att bli mer jämbördig mot fiendens styrka ute till havs.Resultatet blev en svenskutvecklad sjömålsrobot, Robotsystem 15 (RBS 15), som infördes i marinen i början av 1980-talet.

Behovet av pansarvärnsrobotsystemsystem i Försvarsmakten : en förmågestudie

Föreliggande arbete tar sin utgångspunkt i Försvarsmaktens befintliga förmåga att verka med pansarvärnsrobotar. Med syfte att undersöka om det eventuellt finns ett tomrum att fylla för pansarbrytande robotsystem och att jämföra befintligt system mot föregående och ge förslag på önskvärda förmågor. Ur historik, äldre studier, teknisk data från föregående system och intervjuer dras slutsatser som ligger till grund för värderingar av det existerande behovet. Resultatet visar att pansarvärnsrobot 57 har god möjlighet till att lösa given uppgift om systemet tillförs i större omfattning inom skytteförbanden. Miljön styr taktiken, taktiken styr nyttan vilket i sin tur genererar effekt med systemet.

ADOPTIVBARN OCH FÖRÄLDRASKAP I FOKUS -

The aim with my work was to gain a deeper understanding of some adult adopted children?s experiences and reflections about which role parent ship plays for the adopted child?s development of identity. Following questions have been in focus: What does a working parent ship imply, seen from the perspective of adopted child? In which way can the development of identity for the adopted child be supported by a functional parent ship? Semi-structured interviews were carried out with the two following themes: Support and confirmation. The sample consisted of five foreign-adopted between the age of 18 and 37 years.

Gravar i stenskepp : Osteologisk analys av brända och obrända ben från skeppssättningar på Gotland

In this study bone material from six stone ship settings and a total of seven deposits of bones from two sites on the island of Gotland have been analyzed. Four ship settings from the burial site at Gålrum in Alskog parish and two from Tängelgårda in Lärbro parish. The ships contained both cremated remains and inhumations.  Human remains were identified in five of the analyzed ship settings and a minimum of six individuals was identified in total.  Animals were found in three of the ship settings, where one of them contained only the burned remains of a dog. Two of the ships contained inhumations, one in Gålrum and one in Tängelgårda.

?Det var en tyst kamp? : En ekokritisk analys om utvandring och fo?ra?nderliga system i Vilhelm Mobergs Utvandrarna

The purpose of this essay is to do an ecocritical reading of Vilhelm Moberg?s The Emi-grants from 1949. By asking and answering the three following questions; How does a system present itself, What are the different reasons for emigration; Why does differentsystem fit some well and some not.By using two articles from Green Planets - Ecology and Science Fiction to illus-trate two different views; Different parts value in an ekosystem and The Ship as an ecosystem. I have also created, based on the literary text four different terms concern-ing the dynamic system; Stable, Static, Unstable and Collapsing systems. I have found that all system goes through changes, some drastic, that changes the way the parts of the systems fit with in it.

Tecken : En retorisk-semiologisk analys av antirökreklam

This essay studies how advertisements in various anti-smoking campaigns can influence and persuade by using anti-logos as counter-arguments to the tobacco industry's logos. In contrast to tobacco advertising arguments such as freedom (logos), pleasure (pathos) and trademark (ethos) the anti-smoking campaigns create anti-logos arguments with various connotations such as repulsive pictures and sexual implications to influence groups of people not to start smoking or to quit smoking.Advertisement of tobacco does not exist nowadays due to legal restrictions in the western world; however several decades of myths created in the consumer consciousness still exist. Thus one can speak of a tobacco advertising ideology that exists and the various anti-smoking campaigns trying to change that ideology.The purpose of anti-smoking campaigns is to conduct a kategoria of myth that tobacco advertisement has created over the years. Anti smoking organizations do this by creating a new ideology to affect consumer?s attitude toward smoking and the tobacco myth with an anti-myth.

Prediktering av fartygsbränsleförbrukning i varierandesjötillstånd

  During the 2000s, the ship owners have become more and more concerned thattheir ships save fuel. Several projects have been undertaken to exploit the resourcesavailable on board today?s vessels to reduce fuel consumption. As a stepin this the Swedish Meteorological and Hydrological Institute (SMHI) today offera Weather Routing service to ships. By planning your route more effectivelymuch fuel can be saved.This thesis has been about developing a fuel prediction program (FPP) forhow much fuel a ship consumes in different sea conditions.

Kommunikation och Prestation : Aspekter på förhållandet mellan teamkommunikations innehåll, frekvens och problem, och teamresultat, studerat i en militär flygsimulator för grupper

A study of communication content, frequency and problems was performed at the Swedish Air Force Air Combat Simulation Centre, FLSC. The purpose was to investigate the connection between team communication and performance variables, to study communication problems during air combat and to employ and develop the PILOT method of communication problem analysis. Ten fighter pilots and four fighter controllers engaged in simulated air combat beyond visual range in teams on two sides, Blue and Red, with four pilots and one fighter controller each. Eight such training runs lasting 15 to 25 minutes were analyzed with regard to the Blue team?s communication during launch situations, i.e.

Riktlinjer för studier av icke-existerande komplexa sociotekniska system : Erfarenheter från en studie av införandet av ombordbaserad helikopter på korvett av Visbyklass

This report consists of a discussion about suitable methods for studying complex sociotechnical systems that are still being developed. There are large economical advantages with studying new systems before they are completely developed since problems can be discovered early and thereby avoided. It is, however, difficult to study developing systems, there are methodological limitations. These limitations are discussed and recommendations for studying non-existing complex sociotechnical systems are presented.The report is based on experiences from a study of the introduction of a shipboard helicopter on the corvettes that the Swedish Armed Forces are developing. A shipboard helicopter implies high requirements on the hosting ship.
