AbstractSAAB has for a long time used user controlled pilot models in ARES. ARES is a simulation tool used in the desktop environment for simulations and calculations of the JAS 39 Gripen fighter and other aircraft. ARES stands for ?Aircraft Rigid body Engineering Simulation?. To work with these pilot models has been both time-consuming and inefficient.

Stockholms vattenskärning AB in Kungsängen has through the acquisition of a company begun to design and produce aircraft heaters whose origin is early 1970s which follows a high inefficiency in terms of energy consumption and size.The aircraft heater, which is sold worldwide, serves its purpose for customer satisfaction and has done so ever since it was developed in the 70s.Stockholms vattenskärning AB is now investigating the possibility in making the aircraft heaters more efficient, both in terms of energy consumption but also on a more efficient design with the belief that it would lead them to an edge in the market. The aircraft heater consists of several main components whose function altogether is to keep passenger aircrafts warm while they are on the ground.This project has been limited to the further development of the heat exchanger package which accounts for the conversion of the hot medium to the fresh air being carried in to the aircraft cabin. Work has been divided into different phases in order to create a better understanding of the project range and to make it easier to divide the various elements in the time available, 10 weeks. These phases are literature review, situation analysis, concept generation, CAD, concept comparison and writing reports.After the initial literature review was made, a fundamental theory was written which is essential in understanding the remaining parts of the project.With the theoretical part as support, measurements and calculations were made on the current heat exchange package in a situation analysis to ensure its operation and efficiency.In the concept generation phase, the collected facts from the literature review was used as the basis for creating a matrix. The purpose of the matrix was to indicate the two most suitable types of heat exchangers to develop four new concepts out of.In the CAD phase the four concepts was drawn up and then described with text and images.The last phase is the concept comparison where a concept selection matrix is used to function as a decision basis for further production at Stockholms vattenskärning AB. The four concepts have been developed based on the current heat exchanger and is gradually changed into a design of a cross-flow heat exchanger constructed out of stainless sections. The purpose of this is to have gradual upgrading of the heat exchanger as an option, in order not to saturate the market..

Sweden is one of five nations in the world manufacturing fighter aircrafts. Highly advanced technology is needed in order to develop a fighter aircraft. When developing advanced technology, new applications, other than those initially intended occur, spin-off. Some of Sweden?s largest companies are spin-offs from the fighter aircraft industry.

This study investigated the performance and cost of scarification with a tractormounted excavator. Due to variations in terrain conditions the performance variedbetween 0.08 and 0.11 ha/E15h and, with a machine cost of 366 SEK/h, the cost ofscarification varied between 3 330 and 4 750 SEK/ha..

The work describes the development of an adjustment algorithm that will replace today?s manual adjustment of Lead- and Lag-filters at ABB Robotics industrial robots. The adjustment is mainly for the filter parameters in the control system.Three different algorithms have been created to replace the manual adjustment. One of them is based on the criterion from the manual adjustment and another one on optimization of the sensitivity function. The last one is a combination of the two.The report describe the development of the algorithms and how they behave during simulations and tests on real robots.

Background: Performance measurement as a management control tool has received considerable academic attention. As the number of inter-organisational relationships, such as customer-supplier relationships, increases, there is a new scope for performance measurement as a management control tool. In order for a company to assess the effectiveness of its supplier relationships it has to define, measure and evaluate variables that are critical for the success of the relationship. The role of management control, and thereby of performance measurement, has increasingly been discussed in theory. However, empirical research in this area is still somewhat limited.

The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.

SammanfattningDet här examensarbetet har gått ut på att undersöka hur en manual kan utformas för att instruera i att skriva klarspråk om teknisk information.Jag har arbetat utifrån principerna läsligt, läsbarhet och läsvärde samt läst studier i hur en skribent kan förenkla en text. Jag har också utfört en textanalys, gruppintervju och användartest för att skapa en manual som kan vara anpassad utifrån målgruppens behov. I mitt arbete har jag använt mig av principer för att skriva klarspråk. Det är att målgruppsanpassa, använda bekanta ord, skriva en logisk meningsbyggnad och att -strukturera texten på rätt sätt. Manualen blev kortfattad för att passa målgruppen. Den innehåller många exempel för att skapa förståelse och läsvärde..

AbstractStudents at Mälardalen University have long performed their lab on a small turbojet engine in the course Aircraft Engine Technology. Since 2011, the engine has been dysfunctional. This was due to lack of maintenance. Since the lab has been an important element in teaching, the University had decided to get the engine functional again. This thesis project has been a request of Mälardalen University.The task we were assigned to was:1.

This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Södra Skogsägarna and the aim of the work was to investigate the economical and biological output after mechanical planting with Eco-Planter compared with traditional manual planting. Eco-Planter is a tool for mechanized planting, fixed at the end of the boom on a conventional harvester. The study confirms that manual planting is less expensive under normal conditions. However, the differences between mechanized and manual planting are not that big and with technical development and/or increased labor costs together with an improved work organization the system with Eco-Planter could be competitive. The biological output, e.g. planting result and survival rate, seems to be quite good.

Study objectives:Examine ambulance personnel?s perceptions of skills / training and knowledge with regards to the existing mechanical / manual compressions and frequency of training during a work shift. Do ambulance personnel think that mechanical compressions increase survival? Are there concerns that the device could damage the patient?Design: A cross-sectional study, quantitative approach with qualitative elements was conducted.Methods:Questionnaire form, which was answered by 44 ambulance personnel in an ambulance organisation in Sweden. Participants were on a scale of 1-5 to select how they agree with the claims of the study form and also submit their own comments.

Agency theory describes the conflict of interest between the principal (stockholders) and the agent (CEO). Aligning the incentives of executives with those of the owners is the most direct way to mitigate the agency problem. If there is no meaningful link between CEO compensation and company performance, it is doubtful that the large sums of assets in public corporations are being managed efficiently. In theory the solution is simple reward the CEO when shareholders wealth increases. The purpose of this paper is to investigate if there is a relationship between company performance and CEO compensation among Swedish companies, in materials and information technology industry.

Stress is commonly found in society today. This paper aims to examine how work performance, cooperation and team spirit are maintained in demanding work environments. By studying two departments in a public hospital that practises addiction care, our findings suggest the following: If the experienced stress is mainly connected to challenge stressors, it has a positive effect on work performance. By organising work through mechanistic and organic structure, the handling of qualitative and quantitative stress is facilitated. As a consequence, first and foremost cooperation can be maintained, but also work performance and team spirit.
