Fuktkvotens inverkan på oljeupptag och pigmentinträngning i tall (Pinus sylvestris L.) och gran (Picea abies L. Karst) vid impregnering med Linotechmetoden :
Wood has always been an important material for people, and it is used for many applications. As for example, fuel for cooking and heating houses, construction materials and for constructing means of transport. Since wood also is a material that with time biologically degrades due to activity by micro organisms and wood fungi it is important to find ways to protect and further lengthen the life span of the material when in service. One method is to decrease the amount of water in the material by impregnation with an hydrophobic oil. The Linotech method which uses only pure linseed oil is one such possible method.
The aim of this study was to investigate the possibility to at the same time impregnate and stain/colour wood samples of pine and spruce by using the Linotech method.
Bildförbättring över en bildsekvens
When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.
Design av Digital Multimeter-modul för inbyggt testsystem
The thesis work of 15 credits has been performed to interest of Norrtälje ElektronikPartner AB (NEP) in Norrtälje. The aim of the thesis was to develop a prototype for an integrated digital multimeter, designed for one of NEP's proprietary test systems. A digital multimeter module according to NEP's requirement specification, such as physical size and accuracy should be constructed. The module should be able to measure current, voltage and resistance.The final circuit was based on the chosen analog to digital-converter, Maxim integrated´s Max134, which is the main component of the circuit for this instrument. A circuit diagram and PCB layout were made. The result of this project is a constructed DMM board.
Utlandsetablering av små svenska IT-tjänsteföretag
This master of economics paper discuss that the globalization has lead to increasing internationalization among small Swedish IT- companies in the service sector. Sweden has a long history of foreign trade but in the beginning of the industrialization only large companies that produced goods answered for the foreign trade. Before, the Swedish companies begun their operations abroad in fairly nearby markets and only gradually penetrated far-flung countries. Now this is no longer possible. When small companies nowadays seek growth in other countries there is no time internationalize with the same approaches as before, especially when the company offers a service.
Flödesanalys av plåtsammansättning : Strävan mot Just-In-Time och minskat slöseri
The Volvo Trucks plant in Umeå is a highy complex manufacturing facility where the same production line handles a variety of different models. This require flexible and agile processes with high quality standards. This thesis studies the flow of material through a production line and how Volvo can use their existing manufacturing monitoring system to optimize the flow of materials.The goal with the thesis is to identify eventual problems with the flow of materials and to deliver a few proposals on how the production line can improve its productivity. The theory of LEAN, Just-In-Time and Supply Chain Management serves as the scientific reference to this project. By analyzing the flow of material, performing interviews and observing the processes a few problems are identified.
En precisionsstudie av förstärkt verklighet som positioneringsverktyg
This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.
Tillfredsställelse på arbetet och spänningssökande som en effekt av uppväxten? : Sambandet mellan arbetstillfredsställelse, syskonplacering och spänningssökande
ABSTRACTThe aim of this study was to examine the relationship between job satisfaction, birth order and sensation seeking. The sample consisted of 179 jobholders in four different organizations in southern Sweden, with an average age of 44 years (SD = 12,12). A questionnaire consisting of three parts was used to map out and measure the participants? family background, birth order, job satisfaction and sensation seeking. The study showed no significant relationship between birth order and job satisfaction (p = 0,127).
Lactobacilli in the gastrointestinal tract of dog and wolf : isolation, identification and characterization of L. reuteri
Since the first wolf was taken as a companion animal a lot have happened with the biology of these animals. Is it possible that changes in the gut microbiota of the domestic dog are involved in the increasing numbers of animals with gastrointestinal disorders? Probiotics have been proven to promote the immune system of dogs by increasing concentrations of neutrophils and monocytes, decreasing the fragility of erythrocytes and increasing the serum IgG concentrations. Probiotics have also been shown to improve the fecal consistency, fecal dry matter and defecation frequency of dogs. The aim of this study was to find out if the bacterial counts in the gut of dogs differed from the gut of wolves, with the focus on lactobacilli.
Att återställa en naturlig ordning : skogshistoria och restaureringsbränning i Långsidbergets naturreservat
During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in Långsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results.
Långsidberget is located close to areas that were colonized during the Middle Ages.
Vad motiverar till ideellt arbete i ungdomsorganisationer?
Early studies of what motivates volunteering often have had an older sample and youth organizations have not been studied. A survey was used to study motives for volunteering in Swedish youth organizations. The importance of age and years of volunteering was studied. In the analysis 102 persons in age between 17 and 59 years participated. The participants ranked the motives as followed: knowledge, development, values, social, career and protection.
Varumärkesbyggande genom marknadskommunikation : En fallstudie av varumärket Hollister
This study aims to describe how a company behind a well-established brand in the fashion industry has strategically chosen to communicate with their target market. Interviews with four individuals in different positions within the company have generated qualitative data, which is presented and analyzed in relation to the theoretical frame of reference in this study. The results show that the company does not use conventional marketing, but relies rather on marketing based word-of-mouth generated by its customer base due to its unique store concepts. Previous research has shown that this type of marketing strategy is effective and beneficial to the brand equity, a conclusion that is demonstrated to also apply to the survey object of this study. Furthermore, it is also shown that this is largely due to the distinct and coordinated image that the company maintains through strict standardization..
En indirekt metod för adaptiv reglering av en helikopter
When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.
En proteomisk utvärdering av olika metoder för att samla uterussekret hos sto :
This study was performed in order to evaluate if the method of collecting uterine secretion by the tampon-method is representative for use in studies of uterine secretions in mares. Uterine secretion collected by tampon in six mares was compared with secretion collected by aspiration, regarded to be a native sample, at the Institution of Obstetrics and Gynaecology, SLU, Uppsala. Proteinanalysis was made at the Department of Farmaceutic Bioscience, toxicological unit, Uppsala University. Cytological smears and ultrasonography was used to assess if the tampon had caused an inflammatoric reaction that could influence the protein content of the samples.
The results suggest that the tampon and aspirat method do not differ when it comes to proteinconcentration, but the distribution of proteins differ between these different collection methods. This difference could not likely be explained by means of proteins due to an inflammatory reaction from the tampon, since neither the cytological nor the ultrasonographical examination gave any indications of inflammation.
Varmsmidning av aluminiumlegering 6026 T9 : Warm forging of aluminum alloy 6026 T9
In this project forging of aluminum alloy Al 6026 T9 has been performed in the temperature range of 400 °C ? 470 °C. The alloy which was in the shape of a cylindrical billet was formed in a press with the aim of analyzing the effect of different forging temperatures and required press load for optimal die filling. The component?s dimensions were later measured and compared to a reference piece.
