This master thesis work was done at Saab Underwater Systems AB, a company at the cutting edge of underwater technology. Here torpedoes and other underwater vehicles are developed and manufactured. The major customers are navies of different countries, mostly the Swedish navy. The aim of this master thesis is to develop, construct and evaluate an automatic Trim System for Unmanned Underwater Vehicles. The task of the system is to change the position of the centre of mass and the vehicle?s total mass or volume.

Elever ska enligt kursplanerna i teknik få förståelse för de tekniska system de möter i sitt dagliga liv. Genom att eleverna får kunskap om teknik i allmänhet och tekniska system i synnerhet får de möjlighet att påverka sina liv som medborgare i en demokrati. I litteraturen saknas idag studier om elevers uppfattningar om tekniska system. Syftet med detta examensarbete är därför att studera vilka vardagsuppfattningar elever har om de tekniska system de möter i vardagen. Studien utgår från systemteori vilken ger en möjlighet att utnyttja det gemensamma mönster som kännetecknar analys av system.

In Sweden plans to build high speed railways have been around since the early 1990s and the planshave developed to be more precised since. The future Swedish high-speed rail network is supposedto consist of two lines. Götalandsbanan; from Stockholm to Gothenburg, and Europabanan fromJönköping through the Öresund Region to Hamburg.The description of the aim to build high-speed railways in Sweden has in former reports always beento achieve rapid passenger traffic between big Scandinavian cities and Europe. There are almostnothing mentioned about the possibilities of high-speed transports of cargo on these railways. Thisstudy aims to clarify the freight transport market for Götalandsbanan and Europabanan.Today there is only one transport system with high-speed freight trains.

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

SummaryA complete graphic profile program along with marketing material has been produced for seven photographers.The material has been produced in consideration to sell their pictures outside of Scandinaviaand Brazil as first priority. The criterion for the profile is to give a message of quality and ofScandinavia. Through research and interviews facts about typical scandinavian design have beenfound. Since the pictures will be exported abroad, a selling packaging solution has been developed. Theparts that are included in the marketing material are: a brochure, display solution, a website and printingexamples.

When using the digital halftone proofing systems, a closer print match can be achieved compared to what earlier couldbe done with the analogue proofing systems. These proofing systems possibilities to produce accurate print match canas well lead to producing bad print matches as several print related parameters can be adjusted manually in the systemby the user. Therefore, more advanced knowledge in graphic arts technology is required by the user of the system.The prepress company Colorcraft AB wishes to control that their color proofs always have the right quality. This projectwas started with the purpose to find a quality control metod for Colorcraft´s digital halftone proofing system(Kodak Approval XP4).Using a software who supports spectral measuring combined with a spectrophotometer and a control bar, a qualitycontrol system was assembled. This system detects variations that lies out of the proofing system´s natural deviation.The prerequisite for this quality control system is that the tolerances are defined with consideration taken to the proofingsystems natural deviations.

This examination report is a part of a program for Industrial organisation and Economics with specialization in Logistics and Management at Jönköping University. The report contains an analysis of the internal material handling at Kongsberg Automotive, and also an improvement proposal for a new material handling system.The aim with the report is to find a better material handling system and also make an analyse of the existing system. The goal is to shorten the distance for the operators when they order material, and also to increase the productivity.The investigation methods for the report have for the most part consisted of observations and interviews of key-persons who daily work in the production. During some time the actual material handling-system has been observed and some shortcomings have been discovered, and these are also discussed in the report.The shortcomings that have been discovered are for once the indistinct signal that should signal need of material in the production. Some other activities have also been discovered that does not bring any value into the final products.

Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.

The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.

We have carried out a study of a classification system for the Swedish collection at The Royal Library in Stockholm from 1887. It was printed in 50 copies. The constructor, Bernhard Lundstedt, and his colleagues used it as guidance in lack of a catalogue. We regard it a local classification system. Little research has been done on old classification systems, but Francis Miksa points out the importance of examining them.

This degree project deals with the creation of a business system for Gamersneed Sweden. The system is divided into two parts, one windows appliction and one websolution..

As self-service technologies become more common in service provisions, a deeper understanding is needed of how customer satisfaction is affected by automated service encounters. Drawing from theories of customer satisfaction, human interaction, and the dynamics of complex service provisions, the differences between automated and interpersonal service encounters in the initial part of a service provision are examined in terms of customers? evaluation of the service encounter itself, overall satisfaction, as well as the service encounter?s impact on global evaluations and evaluations of other non-dependant service encounters. The study was performed on people travelling by air on Swedish domestic routes. Passengers were asked to evaluate the airline?s performance on different attributes of the air travel they had undertaken, as well as to form an overall evaluation of the service.

In January 2005 the emission allowance system was introduced within the European Union and the first period ends at the end of 2007. The system was introduced in order to decrease the wastes of carbon dioxide and the system is a part of ratifying the Kyoto ?protocol which first period runs between 2008-2012.The idea of the system is to reduce the wastes of carbon dioxide where it costs less to do so and the expenses for the society therefore are as diminutive as possible. Different theories explain that companies can benefit from environment legislation and can depending on the company?s attitude gain competitive advantages improve its productivity and thereby increase its profitability.With this in mind, the study aims at examining how the introduction of the emission trade system has influenced Swedish smaller companies in the distant heating industry, with focus on the factors attitude, innovation, competition and profitability.
