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.

An important process for grid companies in order to reduce power losses in electricity distribution grids is to figure out where and how they appear. This report describes the factors that cause power losses in low voltage distribution grids and methods for how they could be measured and analyzed. Measurement data for consumed and injected energy were collected for twelve low voltage distribution grids owned by Gävle Energi AB in order to analyze the size of the power losses and how the measurement uncertainty affects the collected data. Then models of three of the grids were created in MATLAB in order to analyze the data and the power losses were calculated to be compared to the collected data. Curve fitting were also used as a method in order to analyze the power losses from collected data.The results show that the losses in the studied grids are low.

The objective of this study was to study the agreement between two methods of indirect bloodpressure measurement in dogs and cats and to establish the within-method variation for the methods. The utility and practicality in the clinical setting were also evaluated for the both methods. The techniques evaluated were the oscillometric method and the Doppler ultrasonographic method. Thirtytwo dogs and 26 cats were used in the study and seven dogs and five cats out of these animals had diseases that may effect the bloodpressure. Bloodpressure was measured in both anesthetized and in conscious animals.

This thesis discusses model based tracking of radar echoes in tanks with liquid content. The errors in the measurements are not always random in these cases, and the interference that occurs when nearby echoes moves in relation to each other makes tracking difficult. The tracking problem can be broken down to four parts; track initiation, track destruction, association of the measured echoes to the tracks and to update the tracks with the associated echoes. The radar measurement is primarily made on the surface. However, additional echoes from the tank floor or other structures and double bounces are normally present.

Rapid Granulator is one of the world's largest producers of granulators, which is a kind of grinderwho grinds discarded plastics to granules which later can be reused when pressure molding plastics.The company wanted help in developing a new, or alternatively extending their previous,measurement equipment. The old equipment was hard to use, required changes in the code fordifferent measurement scenarios and had a limited array of measuring quantities. Rapid had an ideaof a similar concept only with a greater number of input ports, better range of applicable sensors andan advanced yet easy to use interface. The system is supposed to be placed at Rapid's test departmentwhere it will be used as a tool for finding faults and provide data which can be used for furtherdevelopment of the granulators.The project's members accepted the task and immediately began searching for suitable componentsfor the system. After the search was completed a list of costs, limitations, sensors, I/O's anddevelopment environment was presented to Rapid's staff.

To be able to measure high-surge voltages and transients with short rise times youneed measuring instruments with a high sampling frequency and large Bandwidth.These surges and transients occur primarily at lightning but can also occur at forexample at connecting errors at an electrical switch-gear. This report describes thework with finding two solutions for measuring and log data from these surges andtransients. One temporary solution where a measurement program has beendeveloped. A second solution where different company solutions have been analyzedto decide which fits best. For these measurement solutions two solutions for bringingdown the voltage has been used.

This thesis has been done at the Unversity of Örebro for Örebro University Hospital (USÖ). In our work we have developed a product for hearing tests to determine hearing thresholds of small children. Our product contains software and a control surface for controlling two separate screens. One of the demands was that our software could handle big file libraries. Reliability and simplicity were essential for the user.In our work we have utilized programming of both microcontrollers and Windows software.

Currently, there are no clear statistics on how the floor plan and room size in apartment buildings has changed over time since the postwar period. The statistics available is average area per apartment which can be found on Statistics Sweden's website. This report has the aim to increase knowledge about how the Swedish home have changed over time.The questions that the report will answer are:For apartment buildings, how has the living area been distributed since the postwar period?Why has the area distribution changed over time?A survey of the houses built during 1950-2014 was made before questions could be answered. A case study was also made which a total of 90 apartments were analyzed and divided into three eras, the people´s home, the million programme and the neomodernism.

Control and comparison of various cleaning methods on restaurants in Södra RoslagenThe purpose of this report is to find out and analyze the efficiency of cleaning methods in restaurant kitchens. The investigation was carried out through unannounced inspections at 89 restaurants in Södra Roslagen (municipality of Danderyd, Täby and Vaxholm). ATP-measuring was done on a plate, a knife, a bench surface and a cutting board. The ATP-method measured the amount of food residue on equipment and working surfaces after cleaning, with a luminometer and swabs. Restaurant staffs were asked to describe in detail how and when the last cleaning was carried out on the surface.

During a fire large amounts of particles and unhealthy agents occur.  Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the extinguish water into the soil and to the groundwater.Recent studies in particles have been conducted. A study by Ulrika Iverfelt (2014) reviled that the particles from a fire contained large amounts of both PAH and metals, which is consistent with earlier analyses. Her column experiments with particles in the size ? 11 microns and ?100 microns in silica sand, reviled that the larger particles was immobilized because the transportation was influenced by sieving or physiochemical particle and surface interactions.The transport of the particles in soil and groundwater is regulated by two main mechanisms: physiochemical surface interactions and straining.

There have been, in some rare cases, difficulties with clamping of inserts with U-holesin their tool holder. According to the complaints, the inserts could not be properlyclamped or could fracture when clamped. A study has shown that variations inclamping behaviour are mainly depending by the position of the screw hole in the toolholder and the centering of the screw hole in the insert.The focus of this project has been the centering of screw hole in insert. It has beenshown that the screw holes are not always enough centered in the insert. Theproblem may occur after a certain step in the production, i.e.

In my project I worked with fluorescent color and fear as a theme together. It was based on my question for what happens when you take all the lights out and highlight a fear or phobia. I wanted to experiment and explore the course of event within the surface of a picture by using this kind of paint.I worked with illustration and pattern to bind the two pictures together. The aim was to investigate what is possible with the picture as a medium and work with contrast to make it as effective as possible. My goal was to make one poster of each fear and to make them work together as a series as it?s best.I asked myself many questions such as;? What happens to the surface, image and room when you use this color?? Will a new quality appear?? What happens when you mix two pictures together on a parallel level that only show in different kind of light?.
