Vibrationsdämpning av värmepump
Thermia Värme AB is one of the market leading manufactures of heat pumps. In order tomaintain this position, the company wants to improve the vibration characteristics of theirproducts. The aim of this thesis is to develop product design changes that lead to a reductionof vibrations in the heat pump Thermia Diplomat 8.The main cause for vibrations in the system is flow pulsation and mechanical forces inducedby the scroll compressor. Vibration is transmitted through the compressor piping and receivedby the heat exchangers, from where it is further transmitted to the connection points for theradiator and heat source circuits.A number of design changes in order to improve the vibration characteristics have beenevaluated through calculations and practical experiments. The changes have included thecompressor and heat exchanger mountings, the compressor suction and discharge line pipingand also pulsation dampening.The results of the experiments show that the vibration levels in the connections for the heatingand brine circuits can be decreased strikingly through changes in suction and discharge linepiping.
Ska ekonomin få styra miljön? : En studie om public-private partnerships
This thesis aims at investigating the two municipality?s Gislaved and Ljungby. Where the aim is to see if there is any connections, between the type and the degree of public-private partnerships, and the municipalities obtained environment performance. In this essay the starting point is that the environmental performance in the chosen municipalities is good.Interviews among local politicians and representatives for the municipalities plastic industries, has functioned as a way to test the hypothesis. Gislaved and Ljungby have thereafter been compared, in order to see if there is any similarity in the sort and the degree of public-private partnerships, and how that will affect the environmental performance. The overall questions in this essay are:How can the cooperation among the chosen municipalities and the local business life be described? What kind of Public-private partnership exists in the selected municipalities?Is there any difference between the municipalities, referring to the degree of cooperation between the municipalities and the local business life? Does the degree of cooperation affect the progress on the environmental performance? The end result shows that the local business life doesn?t have any impact on the environmental performance.
Dimensionering av ventilhus med avseende på skärkrafter
The company Somas, Säffle, has assigned Fredrik Kjellin the project of finding out how ?KVTF DN250?, one of their own valves, reacts on cutting forces under production. They wish to know if and then how much it?s possible to minimize the wall thickness of the valve with neither plastic nor to big elastic deformations caused by processing.The most critical processes have been identified as rough lathing. The study has shown that the marginal for a wall thickness of two millimeters, to fall short of the yield stress in the most critical process, is good.
Nytt ventilationssystem till djurstallar :
There is two dairy farms in Sweden with ability to be opened on both long sides, one outside
Hjo and the other one, Brandstadholm, north of Sjöbo. When there is no measures and results
or not enough literature about natural ventilation and especially on this kind of air inlet, makes
my tests very interesting not only on Alnarp, but among other companies.
I would like to find out if there is any air movements direct on the cows, how high/low
temperature, air humidity, light intensity and noise standard inside the barn. Does
Brandstadholm fulfil the rules and regulations when it comes to climate inside the barn? Could
this system become the new dairy barn instead of the conventional barns in Sweden?
I am going to focus on the animals environment, after all they are the one who is going to
spend the most of the time in the barn.
I used five electrical loggers distributed inside the barn to measure the temperature and one of
the loggers measured the air humidity, every 15th minute. One logger were placed on the
outside which measured both temperature and air humidity.
Klostridier och jästsvamp i ensilage ? orsak, verkan och samverkan
Yeast and Clostridia is a problem in silage for farmers as contaminated silage may result in poor animal health and milk quality. Clostridia can produce toxins that, when consumed, acts as neurotoxins, it may also cause blown cheeses if the Clostridia contaminates milk. The purpose of this study was to investigate the cause, effect and interaction of yeasts and Clostridia in silage. Clostridia are microorganisms which are strictly anaerobic and consume carbohydrates and protein in the silage. Yeast is a fungus that is facultative aerobic and feed on carbohydrates in the silage.
Logistik
The construction industry develops at a high pace today. Because of this the construction companies has to rethink and try to develop at the same pace. One of the biggest challenges in the construction industry today is to improve the logistics since improved logistics leads to lower costs. This is something that the construction companies have started to realize and they are beginning to invest more money in order to improve the logistics. It is especially important to have good logistics when the conjuncture turns for the worse.
Navigering, sensorfusion och styrning för autonom markfarkost
The aim of the Master?s Thesis work is to study and develop algorithms for autonomous travel of a UGV (Unmanned Ground Vehicle). A vehicle for the mounting of sensors has been constructed in order to perform the work. Since the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial navigation is used in addition to GPS, since GPS reception is likely to be diminished in such areas.
Studie av en medeltida husgrund : en analys av bronsfynd från husgrund 6, Västergarn, Gotland
This essay is an analysis of the objects made of bronze found in an excavation Västergarn parish, Gotland, in 2010, conducted by the University of Gotland. The studied material presented in this essay comes from contexts inside, as well as nearby the foundation of a medieval building which purpose is still not certain. The first purpose of this study is to present the bronze-objects found inside and nearby the foundation of house 6, and to see if there are any datable objects. There is also a discussion whether there has been any bronze-crafting in the area. The second purpose is to make a contextual analysis to see if there are any differences between the material found outside and inside of the building, and what conclusions can be made regarding the function and use of the building.
Frost hardiness of grapevine cultivars as affected by ground cover under Scandinavian conditions
Cultivation of grapevine is novel under Scandinavian conditions. We studied the impact of ground cover on frost hardiness of grapevine cultivars in Northwestern Scania in a two-factorial trial with four cultivars Solaris, Pinot Gris, Siegerrebe, Ortega and three kinds of ground cover (open soil, plastic cover and gravel). The study was conducted in a grapevine orchard, planted in May 2009, in Broddarp on Bjärepenisula Sweden (N latitude 56°; longitude E 12°). Soil and air temperature were monitored continuously.
Frost hardiness measurements were performed every second week from late September to early December 2009. Frost resistance, LT50, was determined by electrolyte leakage measurement of the upper stems after artificial freezing at -15 °C.
Skolans betydelse för vårt sociala kapital
ABSTRACTSince Robert D. Putnam first wrote about the causes behind the regional differences in economic and political development in Italy, the theory of social capital has truly flourished in the fields of social science. This days you constantly hear politicians and scholars stressing the important role of the quality of the social fabric to a society?s wellbeing. There all looking at ways to construct policies and institutions that help the spread of social capital.
Flexible Snowboard System
The project, Flexible Snowboard System, has been carried out by the project group independently and is a module developed for snowboarders, ski rentals and ski schools. The problems of today?s solutions are that they cause the user an inconvenient standing position when riding the ski lift or skating the transportation slope, also mounting, adjustments and disassembling of the bindings are time consuming and brings undesired wear to the screws and screw holes. In addition any adjustments require that the user steps out of the bindings and have tools at hand. Flexible Snowboard System is a universal module which means that it can be assembled with all of today?s snowboards and bindings.
?Processutveckling av metod f?r tillverkning av en funktionell tibetansk mejeriprodukt?
Probiotics is a special group of health products on the market. The most common type of these is live cultures of lactic acid fermenting bacteria from raw milk . These include, among others, yogurt and various trademarks such as Hälsofil ®, Acidophilus ®, Dofilus ® and Kefir ®. Such products are often used by patients who are treated with antibiotics to combat the intestinal flora eliminated, thus causing digestive problems. The present work deals with yet another type of health product, viz.
Artisten - den osynliga tillgången? : En kvalitativ studie om synen på musikrättigheter och artistvarumärken som immateriella tillgångar i musikbolag.
AbstractArtists ? the invisible assets; a qualitative study about the view on music rights and artist brands as intangible assets within music companies.This paper is a study of what view representatives from Swedish music companies have on activating music rights and artist brands as intangible assets. Throughout the paper, a discussion is held regarding what the representatives think about activating these intangible assets. From this, we have identified and analyzed possible pros and cons to such activation.Our interest to this question was brought to us when we realized that most music companies in Sweden have intangible assets without activating them. This is, even though these are their main source of income.
Utveckling av barnvagn
After contacting the company Elite Group Sverige AB, who sells strollers under the brand Crescent Baby, it was determined that the project group were to develop a three wheeled stroller which was going to be Crescents first own developed stroller. Only the frame of the stroller was considered within the demarcation of this project however care was taken to the placement of the carry-cot and the wheels etc. Crescent Baby wished for the frame would be smaller than the competitor Urban Jungle, that the frame would have at least three unique selling points and that the number of unique parts was to be minimized. The work began with information seeking regarding strollers, competitors, independent tests, European standards and consumer interviews. After that a number of concepts were developed and past to Crescent.
