Demonstratortest av gassensor baserad på tryckt organisk elektronik och jonledande papper
Researchers at Karlstad University have developed a method for making paper ion conducting. The reasearchers want to test this technique in various applications and produce products that make use of the ion-conducting paper. Hopefully this will drive the development forward and result in new applications for the ion-conducting paper.This study was to test the possibility of manufacturing a gas sensor of conducting paper along with electrodes of conductive polymers printed on the paper. By comparing the paper sensor with an electrochemical cell in which the electrodes of conductive polymer replaces electrodes of metal and ion-conductive paper replaces the liquid electrolyte in the electrochemical cell, it was hoped that it would be possible to measure the oxidation and reduction reactions that a gas could introduce at the electrodes.It was shown that it is possible to measure a potential difference in the range of 0.3 V to 0.5 V between the electrodes when exposing an electrode to 100% oxygen. The reaction that takes place is relatively slow and the reaction rate is partly due to the distance between the electrodes.Since the sensor can measure oxidation and reduction reactions it is possible that, in further development of a sensor, the sensor can be made ??into a versatile sensor with more applications than gas measurement as there are many more ways to oxidize or reduce the electrodes than by exposure to oxygen.During the study there have been discussions and meetings held with various companies in the sensor industry to be able to specify what the market demands of a sensor made ??of paper and the requirements that must be placed on the sensor for it to be interesting for the companies..
Gallringsinventering från helikopter utrustad med profilerande laser och kamera för låghöjdsfotografering
Today Holmen Skog finds and selects suitable thinning stands using data on upper height and basal area. These figures are often based on basic forest data that has been updated with the help of growth prediction models. The problem is that these figures are not always correct. The aim of this study was to investigate if a combination of data from a profiling laser and a digital camera for low elevation photography, can be used for collecting data on number of stems per ha, tree species mixture as well as basal area weighted mean height and upper height for stands. The possibility to use these data to assess the need for thinning cutting was also investigated.Laser data and aerial photographs were collected from a helicopter operating at an approximate height of 100 meters.
Varför och hur integreras medier med svenskämnet? : En kvalitativ studie av tre pedagogers uppfattning om inkluderande arbetssätt
This essay is about why and how the media is integrated with Swedish as a subject. The purpose of the study is to investigate if the teachers who use different media when teaching Swedish consider that this pedagogy develops the students? learning. I also aim to find out if there are any differences and/or similarities between the teachers.To fulfil the purpose I have done a qualitative study with three teachers who work at a school. I have focused on following issues: How, when, where and why do the teachers use media when teaching Swedish?The investigation shows that media is popular today and it is becoming more so all the time.
Läsande lyssnare ? lyssnande läsare. En kvalitativ studie av ljudboksanvändare
The purpose of this thesis is to investigate peoples experience when listening at audio books. During recent years the use of audio books has increased significantly. With that knowledge and the fact that this is an almost unexplored area within Library- and Information science our interest grew even stronger. The thesis is based on two different theories. To be able to place audio books in a context we have applied a media- consumption perspective by asking questions like when, where and how the media-consumption takes place.
Vad är viktigast i staden? : Utveckling av ett lokaliseringsverktyg för stadsplanering
This paper is part of the research programme ViSuCity, a programme with the goal of creating more sustainable urban planning through the development of better visual tools, which ultimately means better communication between various parties of public planning. The paper concerns the implementation of MCE into a 3D program for visualization. Multi criteria evaluation (MCE) is a technique that has been developed during the last 20 years. It merges GIS with AHP, forming a decision making tool for localization of, for example, new buildings.The result is an automated tool that enables advanced analysis of geographic areas.The tool has a very high potential due to the completely automated MCE and it is adapted for people without a technical background, let alone formal training in MCE. It provides great opportunities to test different scenarios, something that should be an important advantage.
Ett tillgängligt och användarvänligt boende : Anpassningsmöjligheter för människor med rörelsehinder och nedsatt rörelseförmåga
In this paper we have theoretically built a house designed for people with impaired mobility. Theessay begins with an introduction in which the purpose of the work, the methodology and thedepth-research part is presented. Then the layout that explains how we intend to adapt the housefor the demands detailed in the depth-research part is presented. In the same chapter variousstructural components, such as different floors and walls, are specified.In the selection of materials we have taken into account the criteria of our specialization andadaptation to the aesthetic aspects, where we evaluate materials based upon our wishes regardingtechnique and form. There are also other aspects that are important in the selection of materials,including that these are adapted to technical traits of the construction elements and installations.In a later chapter the technical installations such as ventilation systems, heating systems,electricity and sanitation are presented, where both technical and financial aspects are describedin detail.
Torkat bioavfall som jordförbättringsmedel
The main project Dry preservation of source-separated organic household wastes involves a new technique for treatment of biowaste through drying. Investigations are going on to determine how the dried biowaste best can be used to close the natural circular flow of nutrients. The objective of this degree project is to determine if the dried biowaste can be used as a soil conditioner. By restoring the nutrients in the material to the ground, the natural circular flow is closed. A declaration of contents, including the nutrient levels, C/N ratio, pH and the electrical conductivity of the dried biowaste, was constructed and a germination test was done to make sure that the material did not inhibit sprouting.
När tiden står stilla går allt så fort : Objekt som minnesbärare
This master thesis deals with the theme of memory, it is through an artistic process I have investigated and peeled off to a specific memory, the hut. It is in the work of the personal memory through a craft process it transforms into something public. The hut is constructed out of corrugated boxes, corrugated boxes casted in clay. To cast an object differs according to me from sculpting the object; it is the function rather than the sensual feeling that is sought after. It is about the clarity and accuracy through the casted object that suggest something vague and indeterminate.
Självgående renslastare till sockerbetor :
Our greatest interest within crop farming is to grow sugarbeets, that?s why we want to
write about something new in this sector. We heard that a new concept had come to
Sweden so we wanted to find out everything about this machine.
This new technique was a self-propelled cleaning loader for sugarbeets. This machine is
supposed to replace a loader and a cleaning machine when the sugarbeets is going to be
loaded, cleaned and delivered to the sugerbeet factory. The cleaning loader picks up the
sugarbeets with rollers from the pile, which is placed close to the road.
Köpbeteendet av impulsvaror inom partihandeln
Purpose: The study aims to increase knowledge of dealers' purchasing behavior of impulse goods in wholesale trade.Methodology: An exploratory survey method has been selected in order to investigate the relatively unexplored topic; buyer behavior of impulse goods in the wholesale. Data has been collected through interview of 27 dealers that conduct business with bulk confectionery sales across Sweden. A semi-structured interview technique has been selected, with a predetermined interview schedule but with space for follow-up questions and discussion.Conclusion: The background to this work argued that there is not much research on how retailers reasons when buying convenience products, or also called as impulse items. It is usually the sale of goods such as several of the informants believe is critical to their business existence. Impulse goods which do not require any effort, has little search time and usually are cheap and suits many customers pockets.
Brikettillverkning på gårdsnivå :
In my work I have chosen to examine the profitability for small scale production of hemp briquettes. My study also includes a review of which briquette technique that is the most common one among small scale producers. The reason that I have chosen this subject is because of the discussions about climate and energy that we face almost every day. I also think the subject is extra interesting in these days when the grain prizes are at a historic high level.
In order for me to achieve a reliable report, a hemp and briquette producer has given me the actual data from his farm. In that way I have been able to make my calculations from a concrete perspective.

Computer programs must give a technical effect that goes beyond"normal physical interaction"to be considered to belong to a technical field. The invention shall be be susceptible of industrial application, which means that it should be possible to reproduce or use in any other industrial way. The reqirement that the invention shall be new means that the technique must not be previously known because of patents, published articles, etc. That an invention shall be a contribution to the state of the art in a technical field means that the invention shall not be obvious to invent for a person skilled in the art. Patents do effect the innovation among the inventers, but in most industries most inventions would be invented independent if there was a patent system or not.
Heuristisk profilbaserad optimering av instruktionscache i en online Just-In-Time kompilator
This master?s thesis examines the possibility to heuristically optimise instruction cache performance in a Just-In-Time (JIT) compiler. Programs that do not fit inside the cache all at once may suffer from cache misses as a result of frequently executed code segments competing for the same cache lines. A new heuristic algorithm LHCPA was created to place frequently executed code segments to avoid cache conflicts between them, reducing the overall cache misses and reducing the performance bottlenecks. Set-associative caches are taken into consideration and not only direct mapped caches.
Hygienisering av torkat bioavfall
The main project Dry preservation of food waste from households includes a new technique concerning drying and storage of dried biowaste as well as a study of the sorting of household waste and further usage of the dried biowaste. A question asked in the project is, can the dried biowaste be used as a soil amendment? If organic waste is used as a soil amendment, precaution concerning hygienic safety risks has to be accounted for. The objective of this M. Sc.
Borrelia burgdorferi : metodutveckling och tillämpning avseende odling och resistensstudier mot komplement, särskilt interaktion med faktor H
The genus Borrelia is a widespread, pathogenic pest and the causative of among others borreliosis or Lyme disease. The vector for the bacteria is the hard tick, Ixodes ricinus and the infection is transferred through a bite. Untreated, Borrelia may cause arthritis, heart damage or neuroborreliosis. Infection is made possible through different strategies for avoiding the body?s complement system.
