This report describes the design and construction of a prototype that automatically aims a microwave link towards a target. The link, that is located on a mobile aerial mast, is used by Saab Training Systems as a part of an infrastructure network. The report also discusses the development of a GUI that communicates with the control unit by Bluetooth.The control unit, called Pan/Tilt-controller, controls the position of the link by stepping motors. One motor controls the azimuth angle and the other one controls the elevation angle.By a GUI the operator enters the coordinates on its own position and the targets position. Hereafter a bearing is calculated and it will be sent up to the control unit.The control unit will sense its own direction by a magnetic sensor that works as an electronic compass.

This master thesis includes a description of how a number of sensors are put together in a sensor platform. It also gives a description of how localization and mapping has been performed with data collected from the sensor platform. Localization is a prerequisite for most of the tasks that can be requested from an autonomous mobile robot. In many situations the GPS signal is not available and hence an additional localization system is required. One approach is to apply localization based on landmarks extracted from the robots surrounding.

The aim of this paper is to examine how mid-level executive officers within Swedish Police respond to subordinates autonomous behaviour, mainly according to Lipsky´s theory on street-level bureaucracy. Questions focused on are:1. Which personnel related obstacles, are preventing the executive officers?2. How do executive officers counter obstacles?3.

The higher status homestead called Kullen is located on top of a small hill just outside of Hova in V?stra G?taland. The house stands on a plateau surrounded by a stonewall. Aerial photos from the 1960?s shows what looks like a big parklike garden behind the house, with a gravel walk cutting through on the length of the garden up to the house.

This master thesis is a study of anaerobic thread lockers and is done in cooperation withÖhlins Racing AB, which is a Swedish manufacturer of vehicle suspensions.The suspension in vehicles is constantly exposed to high vibration levels and a suspensionunit has several screw- and cylindrical joints. As an extra safety precaution so that thecomponents in the suspension doesn?t fall apart when using the vehicle, an anaerobicthreadlocker is added in these joints. The handling of these threadlockers is not totallyharmless and could lead to allergic reactions, and therefore there are Swedish laws to limit theuse of these. However, new types of anaerobic threadlockers have recently been launched onthe marked that are not considered under this law.

Traditionally, mining has been performed mechanically with implementation ofyesterdays (and older) data. Several mining companies have started to useautonomous technology and robotics in the production areas although the harshmining environments make it unsuitable for today's electronic equipment. Despite allthe obstacles along the way of digitization, there seems to be no end in sight as thisdevelopment continues. This thesis focuses on what the mining industry is aiming forand why the mining companies are interested in these technologies. The actors of themining industry can be found to have a vision for the future mine, a production with ahigher degree of digitization and resemblances to a factory.

In time with HolmenSkog district Egenskog Norrköping´s decreasing mountain of cleaning, the office started to look around for new alternative cleaning strategies to lower the costs connected with cleaning. One option was to make the inventory strategy more effective and after a phonecall with the head of the district, Jonnie Friberg, the planning started to try inventory in pictures taken from a helicopter. The pictures was at last taken from a digtal camera and the vegetationheight was mesured with a laser. The gear was supplied from Kallax Flyg AB, Luleå. In the trial 15 stands was selected depended on age and different mixtures between pine (Pinus sylvestris), spruce (Picea abies) and birch (Betula pubescense and Betula pendula).

The area of Lycksabäcken northwest of Lycksele is a national interest of natural conservationbecause of its geological values with many unique landforms. Many of these landforms indicatethat the deglaciation process in the area was very complex. However, the deglaciation process inthe area has not previously been fully understood. The aim is to add to the knowledge of theevents that took place during the last deglaciation. To do this, the glaciofluvial landforms in thearea were mapped by studying aerial photographs with a Wild Aviopreter and a five-day fieldinventory of key areas for the interpretation.

Denna uppsats syfte är att ta reda på om euron är en internationell valuta och omeuron kan konkurrera med dollarn om titeln som världens ledande valuta. Teori omvalutamarknaden, en valutas uppgifter och vad som avgör vilken valuta som användsinternationellt behandlas och för att kunna svara på uppsatsens frågeställningar (syfte)redogörs siffror på eurons internationella användning. Sådana siffror visar att euron ären internationell valuta då den används i valutans funktioner internationellt, men attdollarn fortfarande är den världsledande valutan utan att vara särsklit hotad i sinställning av euron..

Sweden is dependent on secure sea transport. Shorter disruption of imports of fuel and crude oil can be managed with an emergency stock, but a prolonged halt in imports creates problems. For industry, the vulnerability is greater. Fragmented production chains in combination with expenditure reductions in inventory causes a dependency on proper transport of intermediate goods in the manufacturing industry. A lengthy disruption thus involves disruption of production for both domestic consumption and for export goods containing imported parts.In order to secure shipping routes with a limited number of vessels, Mine Counter Measures (MCM) capacity is required, and according to the Armed Forces, developed with new sensors and autonomous vehicles.

The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.

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.

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.
