Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.

Holmen Skog is one of the largest forestry companies in Scandinavia and they depend heavily on a large network of forest roads for production and logistics in connection to their forestry operations. The company recently introduced a new system for planning of road management. The system will also be developed with the intention to facilitate the monitoring of actions performed by road contractors. This report will provide information to support future decisions regarding further development of the system, after its introduction. In addition to a presentation of results from interviews, the report also provides a smaller study of the different subjects associated with roads, process work and process development. The study is largely based on interviews with road contractors that perform work for Holmen Skog today.

When models are used to describe physical phenomenon during development or modification of a technical system, it is often possible to reduce both the time needed and the overall development cost. With the use of models it is also possible to investigate the potential of the selected solution, without the need for any expensive details and testrigs. In many cases it is also not possible to test all the aspects regarding the functionality that are desired from the system, without using the complete and final product.In this case a model based approach has been used to optimize the different parameters in the new snubbing mechanism for the Nose Landing Gear Retract Actuator on the JAS39 Gripen.During the simulations, upper and lower boundaries were calculated for the length of the spring and the diameter for the restrictor. The governing constraints were given by the requirements for the retraction time during cold conditions and that the amplitude of the alternating loads in the uplock mechanism were brought to an acceptable level.The most promising results from the simulations were then used in a limited number of trials in the hydraulic rig to verify that the configurations comply with the requirements.The final parameters for the snubbing mechanism were chosen to 35±1mm for the spring and 0.4-0.5 mm diameter for the restrictor..

As break downs of production transformers are costly and often result in long outages it is essential for reliability of operation that the transformers are manufactured to be robust. The aim of this M.Sc. thesis is to investigate if deviations should be made from the standard IEC 60076 ? Power Transformers in order to describe a robust large power transformer for procurement.The investigation has been conducted in three stages. In the first stage a definition of the term robust was developed in consultation with the client Vattenfall Vattenkraft.

Uto?s berggrund metamorfoserades ca 1,87-1,78 Ga na?r en o?ba?ge kolliderade med den arkeiska kratonen. Tidigare deponerade karbonater, vulkaniter och gra?vackor blev metamorfoserade i samband med kollision och senare exstensionell kollaps.

This thesis is a survey and also an investigation of the different factors that affects the cracking that occurs in the inserts at AB Sandvik Coromants production in Gimo. The work that has been done has focused on two main factors, namely, powder characteristics and pressing parameters.AB Sandvik Coromant produces tools and tooling systems for metal cutting. They have some problems in their production of inserts. The problem is that cracks sometimes occur in the body of the insert, after it´s pressed. In order to investigate this, a preliminary study was made in which production principles were studied.

Today electronics becomes more and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a big gap between the degrees of automization for the two parts and makes the analog parts the bottleneck in electronics develop. Research is ongoing at Electronics systems group at Linköping University target the increase of design automization for analog circuits. An optimizationbased approach for device sizing is developed and for this a good optimization method is needed which can find good solutions and meet the specification parameters.

Despite ongoing efforts toward equality, persistent wage gaps between men and women in Sweden still remain, particularly within male dominated industries, such as finance. Gender equality is a prominent topic in public discourse, yet progress towards achieving equal pay between men and women continues to be slow. This study aims to contribute to the research area and offers a unique perspective by examining gender related expectations from both men and women, managers and employees. The purpose of this study is to investigate whether, and if so how, gender related expectations influence salary setting processes in the financial industry. Through a qualitative study based on semistructured interviews, the study explores how both employee?s and manager?s gender related expectations affect attitudes, salary negotiations and potential outcomes of salary setting.

This thesis has been carried out onbehalf of Lindborg & Sons in Örsundsbroand is a concluding part of the Bachelorof Science program in ConstructionEngineering at Uppsala University. Theaim of the project is to make a plea fora database of good examples of themachine room types using Revit drawingprogram, and work out a correspondingworksheet .At the start of the process it becameapparent that there were somedifficulties in using Revit to creatingmachine room types of the variety whichthe company builds. For modelling ofoblique, curved and irregular lines, Ihad to use my AutoCAD Architecture andthen import them into Revit.The creation of calculus in Excel wastime consuming. On the other hand, it isa one-time work to create the template.The advantage of Excel is that there isno need for a re-calculation at the costof various types of machine hall. Allthat is needed is to replace the variousparameters.

Transportation constitutes a large part of the forest industry's raw material costs. Transport also contributes a significant proportion of the carbon dioxide emissions. In order to reduce both the cost and environmental impact different types of decision support are required. These, in turn, require extensive information about the road network and correct information on road path selection and transport distances. In the development of national road data base for forestry (SNVDB) a road selection application has been included.

The association between social parameters (i.e. socio-economy and level of education) and voting behaviour has been reviewed and analysed based on data from municipal council elections in Stockholm and Gothenburg in 2002. Some social scientists argue that the class voting is in decline and that new social cleavages have emerged. However, by using regression analysis techniques, this study implies a strong dependence of voting behaviour on social parameters, such as socio-economic status (SES) and level of education. Socio-economy appears to be a dominant predictor in the analysis.
