This thesis describes how the development of a mechanical enclosure to an alarmsystem proceeded. The project was made on behalf of Inferno Light Indusec AB.The goal set to this housing would offer a home alarm in which Indusec?s uniquesound system would give the customer a new alternative on the market. They wantedto, among other things, create an aesthetically but at the same time affordable alarm.The aesthetic theme is something that is missing in today?s market.

Många organisationer har ett behov av bemanning hela dygnet alla dagar i veckan. Personal vid sådana organisationer organiseras i arbetslag som enligt ett arbetsschema löser av varandra under dygnets gång. Beroende på hur dessa arbetsscheman utformas kan de få en negativ inverkan på personalens hälsa. Den här rapporten handlar om utvecklandet av en algoritm som genererar arbetsscheman med ergonomiska riktlinjer, det vill säga arbetsscheman som utformats på ett sådant sätt att negativa effekter på personalens hälsa undviks. Algoritmen som utvecklas baseras på optimeringsalgoritmen Squeaky Wheel Optimization.

AbstractMotor sports have been around as long as motor vehicles have been. Sports are often seen as costly polluter but in the same time the motor sports have encourages a large part of development, both for vehicles and other industries. Inventions like rear mirror and ABS brakes come from motor sports. One way to once again drive development forward while making motor sports carbon-neutral is to run the race cars on hydrogen. In this thesis, the goal is to convert a spark ignition engine for hydrogen operation.

The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.

Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction.

This report summarizes a Bachelor Degree Project in Integrated Product Development,carried out during the spring semester in 2007 by three students at the Product Design Engineering programme at the University of Skövde. The project was performed as an assignment for KinBag ab, a sister subsidiary to Kinnegrip ab in Lidköping, who develop,manufacture and market the golf bag KinBag, a bag with an integrated wheel carriage system. The purpose of the project was to redesign the golf bag to attract a target group consisting of golfers aged between 20 and 40.The layout of the project was as follows: The project began with a feasibility study where different problems were identified with the basis of a market research which eventually was summarized in a dynamic specification of requirements. The feasibility study was followed by a generation of ideas which contained everything from sketches to simple mock-ups with an intensive amount of thoughtful brainwork and information gathering in between. This ledto the development of a number of design concepts, both on an overall level and on different parts of the golf bag.

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

In studying the art of Counterinsurgency Warfare we are usually inclined to the reading of several books regarding this matter. Because of this some writers have the power to influence the minds of the reader. This can be of great benefit since it enables information sharing and for the reader a chance to learn from the triumphs, but also mistakes of others. However each writer is the creation of the time and context under which he existed. Because of the wheel of time certain things change, and because of the context a myriad of factors came into play affecting the outcome and product of the doings and thoughts of that specific occurrence.

Purpose of this study is to describe and analyze school social work in rural area and being alone in social work at the school welfare/health team and how this affects the individual, professionally and privately.The theoretical framework highlights the empirical data through Goffman's dramaturgical perspective. The study highlights school social workers role on the scene as Goffman divided as the front and rear arena and how school social worker find strategies to cope with it alone work it takes to be a counselor in rural areas.One way to handle her role involves acting in one of the following three characters: the self-employed, infiltrator and tough guy.The study describes how the social worker harboring the stress in the profession; through recovery - physical and mental, on the back stage, backstage.On stage there are other players such as student health team, which also acts and affect what happens on the front stage.School social workers are working hard to position itself in relation to other professions in student welfare/health team and to have a mandate to act.In the analysis, it appears that the school social workers want a clearer role profession/ occupation profession and mandate to act, which may be complicated by today is the only counselor in student welfare/health team lacking identity. There is also a desire for further/ continuing education, but this is seen as an organizational pitfall when the manager does not have the same educational background as school social worker.Ultimately, it is the peripatetic life as a social worker at the school who is considered the most exhausting part of the work as a school social worker in a rural area. There is a great desire among the interviewed school social workers to have fewer schools to relate to and work on..

At night, the visibility is reduced and the demands on the driver increase. A safety system that enables the driver to discover warmer objects in the surroundings when the visibility are reduced, such as the Vision Enhancement System (VES) contributes to safer night-time driving. Since the benefits of this system are established, it is of interest to investigate different design aspects. The VES display has in earlier studies been positioned in front of the driver but different display positions such as peripheral placement should be evaluated. The present simulator study is an investigation of the effects of different display positions inside the car.

This thesis work has been performed at Volvo Aero Corporation in Trollhättan, at the department of ?hot structures? involving aircraft engine GP7000. The purpose with the study was to investigate the possibility to reduce size of the forging of flanges on the rear turbine frame when purchasing. Thereto examine the parameters that affect the flanges motion during the manufacturing process. The goal was to provide Volvo Aero with foundation to later bring in slimmed forgings.

Vehicle simulators are becoming more common in vehicle industries. Company earns lot of money on simulations instead of real tests. Real tests are necessary but not made so extensively as before.In this thesis the building of an vehice simulator will be described and a comparison between three different cruise controls. The three cruise controls are PI-regulator, a regulator who regulates after positions in the terrain and a MPC-regulator. The reason for choosing this three is to see the difference between simple regulation and more complex regulation with respect to fuel consumption, travel time and complexity.The vehicle simulator is made in Matlab/Simulink, Visual Studio and Open Scene Graph.
