Syftet med detta examensarbete var att lära sig att genomföra ett programutvecklingsprojekt under realistiska förutsättningar och därigenom få erfarenheter som är relevanta för yrkeslivet. En grupp på åtta personer arbetade under en termin med ett projekt som handlade om utvecklingen av ett obemannat luftburet radiometrisystem. Ett lättare system efterfrågades för att förlänga flygtiden. Under utvecklingen tillämpades metoder från Semat, Scrum och Extreme Programming. Utvecklingsarbetet fungerade bra och en lösning för problemet togs fram, systemet hann dock inte implementeras full ut.

This degree project has been carried out by Carolina Rapp and Jenny Tauson, students at Innovation and Design Engineer program at the Faculty of Technology and science at Karlstad University. The project was carried during Spring of 2009 and took 15 weeks of full time work.  Doppelmayr/Garaventa Group is an Austria/Switzerland corporate group and its associated company Doppelmayr Scandinavia lies in Sunne, Sweden. Doppelmayr/Garaventa Group is the world quality and technology leader in ropeway engineering. The degree project goal was to develop a new shaping of a surface lift. There are two kinds of surface lifts, platter and T-bars. The two kinds of surface lifts have some variation in design but only minor differences.

A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

Bakgrund: Ungefär en miljon människor mister sitt liv av suicid årligen i hela världen. Det finns psykosociala, kliniska och biologiska faktorer bakom suicidala handlingar. Huruvida suicid utvecklas belyses i en suicidal process. Vården efter ett misslyckat suicidförsök upplevs oftast obehagligt och känsloladdat för suicidnära individen. Målen med vården är bland annat att främja patientsäkerheten.

 AbstractA walk at Karlstad's cemetery and burial - grounds is like a strolling in an architectural park with trees, bushes and flowers. But these parks are different; they are filled with dead people, their memorial stones and their life stories. This world is full of socially, economically and culture differences from different times from 19th century till today's society. The cemetery - and burial - grounds in Karlstad can tell you about 19th century influences just by looking at the stones and where they are placed. Influences from the religion, the Christianity, which symbols for example is the cross, the birds and the sun that rises or falls, but also phrases that is directing to the bible.

Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.

Logistics planning for a construction site is usually limited by traffic flow to and from the workplace. The geographical location of the construction site is determined by roads around the workplace and opportunities for well-functioning logistics. Inventory of material is often impossible because of the frequently small workspaces. As a result, a concern relating material handling remains . Even before the establishment of a construction site, it is required in the construction industry to eliminate errors that might arise in the planning stage.

In 2013 a new emission standard for heavy trucks was introduced and hence a number of new parts was brought in to Scania CV AB. This created a need for modifications in the silencers flow. The flow is highly complex involving several suppliers, call off methods and different models of silencers. The aim for this project was to improve the existing silencers flow. The flow, from supplier to assembling, has therefore been mapped.

During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.

Investment aid is a part of the Rural Area Programme, which contains support to Swedish agriculture and the countryside. There is a new programme every seventh year and SLU (Swedish University of Agriculture) has the mission to perform the evaluation of the previous programme, which lasted between 2000 -2006. The investment aid's aim is to support investments that, among other things, support the adaptation or conversion to more environmentally friendly production methods, improves the product quality, develops new or complementing activities, and improves the environment and the animal- and working environment. The question is if it's only money that matters for these kinds of investments to be done and what has happened with the money that was paid? This thesis investigates how the investment aid has affected the receivers.

AbstractBuilding Information Model/Modeling/Management (BIM) is a tool that allows for efficient working methods. BIM saves time and money while providing the potential for visualization. This method of working is based on a 3D-model, and then a fourth and fifth dimension are connected. 5D modeling means that a spreadsheet creates cost estimates based on the 3D model. This provides opportunities to carry out calculations in the early stages of the projects. Calculations are currently performed manually and do not contribute to the development that the construction industry requires.

Quality can be defined as the ability of a business to satisfy their customers? needs and expectations. Total Quality Management is defined as the way to prevent, appraise and improve the entire organization to increase the product quality. In order to systematically increase quality in an organization, there are different quality systems in use. One example is process management, which is to divide the activities of processes.

As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.

The last decades the populations of wild boar (Sus scrofa) has increased rapidly over the species? entire European range, including Sweden. This is followed by increasing human-wildlife conflicts as a result of the wild boar foraging behavior, causing damage to agricultural crop fields due to trampling and feeding. To be able to minimize damage we need more knowledge of where in the fields the risk of damage is high and what features in the landscape that affect this risk. I analyzed damage distribution in relation to the distance to six different landscape features; forest, road, ditch, building, game field and bait station, in the study area, the Island Mörkö in eastern central Sweden.
