Rotationsdämpare med integrerad fjäder

This final thesis is carried out at BAE Systems Hägglunds in Örnsköldsvik. The mission was to construct and integrate a new semi-active damping unit in the terrain vehicle BvS10. Questions that came up during the process, among others, was how to mount the damping unit to the vehicle in a flexible way without exposing it to unnecessary wears.A generation of the concept is made in 3D using CATIA V5 of a possible solution to the problem. The idea is to weld the unit to the skid girder which is one of the main constructions of the track system. In this way the damping unit will come closer to the track system, which will partly protect it from impacts from below and minimize current problems with breaking forces in the torsion shafts.The complete construction was then analyzed, first by theoretical calculations and then with the FEM-tools in CATIA V5.

Environment simulation of track-based systems

Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.

Att lämna skyttegravarna - Underrättelsetjänstens roll för track two diplomacy och konflikten på Nordirland

Denna uppsats är en fallstudie av upplösningen på konflikten på Nordirland. Den söker med hjälp att teoribildningarna kring ?track two diplomacy? och underrättelsetjänst utröna vilken roll ?track two diplomacy? spelade för fredsprocessen på Nordirland, och om underrättelsetjänst krävs för denna form av diplomati i polariserade konflikter ska kunna verka.Konflikten på Nordirland var en mycket polariserad och långdragen. I fredsprocessen har track two diplomacy varit förekommande, och i konflikten var underrättelsetjänsten en utmärkande faktor, detta gör Nordirland till en god fallstudie.Studien visar att utan track two diplomacy hade inte fredsprocessen givit så goda resultat som det reella. Samt att underrättelsetjänsten genom MI6 officeraren Michael Oatley haft en viktig roll för denna diplomati, genom att skapa och utnyttja kontakter med IRA vilket ledde arbetet till konkreta diplomatiska resultat.

Samspelseffekter vid kapacitetsförbättringar. : Exempel från Dalabanan.

The trend in the transport sector is moving towards eco-friendly, fast and convenient transportation,this results in higher demands on railway transports. To meet the demand and quality requirements,the Swedish railway network will have to expand. The cheapest way is to expand little by little butwhat impact do these small steps actually have on the capacity?This thesis examines the interactions of different improvement for the capacity on a single-trackrailway. Through simulations in the software tool RailSys this report studies what effect block signals,extra meeting stations and rebuilding existing two track passing loops to three track loops have onthe capacity.

Tingsryds Travbana

Our bachelor thesis is a visualisation made in 3D-graphics of how the horserace track in Tingsryd perhaps will look like in the future, complete with a miletrack, steeplechase, and other horserace courses. Today, the race track is only in it?s building phase. The inner field-group in Tingsryd needed presentation material to show their eventual sponsors, so they contacted us at Media Technology, and we instantly decided to give their idea a try..

Navigering, koordinering och översikt

The advantage and the possibility of keeping track of a number of vehicles to make work practice more effective and smooth is today a favorable choice for Visual Units Logistics customers. We?ve been evaluating the software and trying to take it one step further and letting not only the individual user, but maybe, the company as a whole benefit from its advantages. This has been done by using methods like letting ourselves get to know the software, user case studies, workplace studies, interviews and future workshops. This resulted in a prototype introducing a new function designed with all collected data in mind trying to make the software, Visual Units Logistics, even more effective for the every day work practice of the user.

Utveckling och tillämpning av det muskelstyrda datorspelet EMG Track Game.

Electromyography (EMG) is a technique that measures muscle activity, whichmeans detecting the electrical signals that travel through the muscle in connectionwith muscle contraction. This project deals with how EMG can be used tocontrol a computer game.The project is centered around the game 'EMG Track Game' which has beenconstructed as part of this work. 'EMG Track Game' is controlled by twoelectrodes fastened on the player. These are attached to two selected musclesand control the motion in one direction each, one up and the other one down.The game is constructed in the purpose of being used in several elds of application.Among these are as entertainment, training equipment and a tool inresearch related to EMG and muscles.To highlight a possible application a study concerning muscle control has beenconducted. It answers the question of whether players score better with theirdominant arm in comparison with their non-dominant one.

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.

Gruppmålföljning av markobjekt

This Masters Thesis considers tracking of ground targets. Since ground targets often are difficult to detect with sensors a track is easily lost in ground target tracking. The main question in this thesis is whether information on close targets and observations of them can be used to make the tracking more reliable. An algorithm using Kalman filters and JPDA-association to create a group track for vehicles travelling together has been implemented in Matlab. Using the state of the centre of the group the state of a vehicle in the group can be updated.

Social E-handel?: - Hur närvaro av andra besökare påverkar utvärderingen av en webbsida

Internet - and the website - has developed into an essential key for the relationship between enterprises and its customers. Today, a website might be the first or only impression a customer gets of a company. With this in mind we have focused our study on customer evaluations on websites. Social presence and its impact on people have so far mostly been given attention in the research of behavior in physical environments. However, in the electronic marketplace this has so far been overlooked, which is why our aim is to study how the presence of visitors impacts other visitors on the same website.

Tillämpning av GIS-analyser i MKB

The reason for performing an Environmental Impact Assessment (EIA) is to incorporate environmental concern in different kinds of plans and projects. The purpose of such an assessment is to identify and describe direct, indirect and cumulative environmental impacts.Geographical Information System (GIS) is a tool that can be used to combine spatial extension of both sensitive areas and different environmental impacts in a quick and easy way. Because of that, descriptions of environmental impacts and motivation of different standpoints on a specific issue can be more correct and easier to make if GIS is used as a tool.Hence, GIS can contribute to improve the quality of Environmental Impact Assessments. If the benefits of using GIS are to out weight the costs, geographical information of satisfactory detail, actuality and accuracy need to be available at reasonable prices.In this paper, case studies are carried out for three different geographical analyses to investigate the use of GIS as a tool in EIA. From these case studies, more general conclusions about the benefits and limitations of using GIS for Environmental Impact Assessments are also drawn.
