Modellbygge av mekaniksystem och riktmotorer i stridsvagn 122

This master thesis is one part of a project, called ?StabSim?, with the purpose to develop a simulation model for the align and stabilisation system in Main battle tank 122. The origin of this project is that it should be possible to make control analysis without risking any hardware. Besides that it will be easy to change components in order to investigate the behaviour of the system. The report includes modelling of tower and weapon mechanics and also the modelling of the synchronous motors, which control these.

Modellbygge och regulatordesign av tröghetsmomentsimulator tillreferenssystem för stridsvagn 122

This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a Main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..

Vikingatida sjöslag

Analys av nivåproblematik i dränagetank på Ringhals 1

The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.

En ny metod för att designa rakettankar

I denna rapport beskrivs ett ny idé för rakettankar. Beräkningar och simuleringar görs för att avgöra om idén håller. Idén går ut på att sätta en tank i en tank, för att på så vis möjliggöra en arbetfördelning mellan den inre och den yttre tanken. Den inre designas för att tåla låga temperaturer och bränslets vikt, medan denyttre designas för att innesluta allt under ett högt tryck, utan att väga speciellt mycket. Beräkningarna visar att idén är speciellt bra för tankar avsedda att innesluta flytande väte.

Tankinsats för dieselbilar : Från idé till prototyp

This thesis describes the development of a tank insert for diesel cars, from idea to a prototype. The idea is to design an insert which makes it impossible to refuel petrol in a diesel car. The insert shall be installed in the existing tank opening on diesel cars. The tank insert is designed for the Swedish company SverigeGrepen AB located in Vänge, just outside Uppsala. Their main product is a pitchfork that is ergonomically designed and durable.A pre-study were performed in which information relating to fuel caps, tank openings, petrol- and diesel nozzles were collected.

Karolinsk Stridstaktik : artilleriets och pikens roll 1700-1712 samt bataljonens stridsformering

From a new perspective, this paper will examine the artillery and the pike role in the period 1700-1712 and the battalion´s battle formation in the Caroline combat tactics. Carolinian battle tactics were practiced during the period 1700-1721. The results from my study will be compared to existing research opinion regarding the selected subject areas, if the result confirms the thesis or question the existing research opinion. The source material used consists of eyewitness accounts from the period consisting of diaries, memoir, biography, general muster rolls and historical literature covering the subject. The analysis shows that the Caroline artillery took part in 12 battles during the period of 1700-1712.

Modellbaserad ekoföljning i vätskefyllda tankar

This thesis discusses model based tracking of radar echoes in tanks with liquid content. The errors in the measurements are not always random in these cases, and the interference that occurs when nearby echoes moves in relation to each other makes tracking difficult. The tracking problem can be broken down to four parts; track initiation, track destruction, association of the measured echoes to the tracks and to update the tracks with the associated echoes. The radar measurement is primarily made on the surface. However, additional echoes from the tank floor or other structures and double bounces are normally present.

En studie av slaget vid Verdun och de taktiska grundprinciperna : Är Doktrin för markoperationer applicerbar på utnötningskrig?

This essay is about the tactical basic principles as they are mentioned in the Swedish Doctrine for land based operations (2005) and the German side during the battle of Verdun 1916. The purpose of this essay is to clarify whether the used doctrine is appropriate to use on future attrition battles.        This is done by a case study of the German side during the battle ofVerdun. In this case study indicators of the basic principles are then identified and analysed with the starting point at the two questions that the essay is based around. The essay starts with an introduction where above is attended, in the second part the basic principles, the background to the battle and the battle itself is described. Finally the tactical basic principles are analysed and discussed based on the questions that the essay is based on.In the analysis and the discussion the conclusion is drawn that the tactical basic principles were present on the German side during the battle of Verdun and that they are of a general character and may be applied on both attrition warfare of 1916 and modern battles of attrition..

Nivådiagnos med sensorfusion : Utveckling av koncept för nivåmätning i lutande tankar 

Today?s system to measure the volume in a tank consists of a vertically placed sensor. When a vehicle is tilted the level of the fluid might change and if the volume is calculated based only on the information from the sensor it could result in a incorrect value.This thesis exams a new method to calculate the volume in tanks by using sensor fusion to crosscheck the i formation from the level sensors when the vehicle is tilted. The information is then used to see if it is possible to identify the grade of tilt by the change of fluid level. If the grade of tilt can be measured then the volume can be calculated in a more accurate way.

They shoot each other? : Våldet i en adaptationsstudie av Hungerspelen och Battle Royale

This thesis presents a qualitative, comparative study of the violence in the adaptations of Hunger Games (Tony Ross, 2012) and Battle Royale (Kinji Fukusaku, 2000). By analyzing the function of violence in a single scene in each of the movies, and comparing it to the literary original, the study aims to explore if there are any differences in the representation of the violence in the two media. The study also briefly discusses whether the violence has any function in bringing the story forward in both the literary sources and in the films and what the motivation for the violence is. "The study also includes a brief analysis of the narratives in relation to the monomyth established by Jospeh Campbell. Specifically, I discuss the similarities between Hunger Games and Battle Royale, which are two stories that have been created in two different cultural traditions, and whether or not we can say that the stories derive from this monomyth." The result concludes that the monomyth can be found in both stories, but that the scenes which is analyzed has to be put into the context and furhter story of the film to be of any relvance to the theory.

The battle of the forms

När två parter sänt varandra sina respektive standardavtal, utan att någon av parterna protesterat mot innehållet och det i efterhand visar sig att dessa standardavtal strider mot varandra, uppstår konflikten the battle of the forms. Det är denna situation som vårt arbete behandlar. Vårt syfte har varit att med hjälp av olika utländska lösningsmodeller visa hur konflikten kan lösas eftersom det i Sverige varken finns lagstiftning eller klar och tydlig rättspraxis att använda sig av. En inblick i hur konflikten behandlas i England och USA har gett oss mer material att jobba med. Vi har använt oss av en deskriptiv metod.
