Energikonsumtion hos en diskmaskin

The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.

When Bad is Good

Within the last year many companies have proactively started to communicate their flaws and weaknesses, believing that this will lead to they being perceived as more personal and human. Dominos Pizza is one of many examples of a company using this practice as a strategic tool for communication. However, the problem concerning the above arises as we found that there was a very limited amount of research defining the effects of communicating flaws, where the company's both dispatcher and initiator. Our study aims to fill the gap between this growing trend and the limited research explaining the communication effects. The study was carried out as an experiment where a total of 420 respondents participated.

När goda råd är dyra: En fallstudie av användandet av konsulttjänster i den ideella sektorn

The goal of the case study was to explore the tendency of NGOs in Sweden to hire commercial consulting companies. The main interest was to see what the key reasons are for NGOs to hire private consulting agencies, but also to explore what problems that might be associated with such relationships. Interviews were carried out with representatives of the consulting agency, with its clients as well as with other NGOs that were identified as potential clients. The interviewed NGOs and government agencies were found to approve of the use of commercial consultants.

Utvecklandet av en portabel solcellsmodul i miniformat lämpad för Nordiska klimatförhållanden : Teoretiska, praktiska och beräkningsmässiga analyser

The construction industry is always looking for ways to make the work more efficient aswell as minimize the waste of money in general. At the same time the industry is showing alow awareness of logistics which has to increase in order to improve the industry in thesekind of questions. Projects located in the inner city have high demands on the logistic andthe handling of material due to the so often limited space for storages of the material. Dueto this the purpose of this report is true a case, study and analyze what kind of factors thereis to take into consideration during the materials way from the supplier to the workstationin a project located in the inner city. The data for the report was collected with the help of acase study, and in three different ways.

Förbättring av mjukvarubibliotek för parallellberäkningar med programmeringsmodellen Chunks and Tasks

Chunks and Tasks is a programming model based on the C ++ programming language. This programming model is used for electronic structure calculations, among other things.The purpose of this project is to improve the CHT-MPI software library for Chunks and tasks, so that calculations of matrix-matrix multiplications are performed more efficiently than they do with the existing software library. The software library is based on the work stealing method, which is a method the software library for Chunks and Tasks uses for the distribution of the calculation work. The considered way to improve the software library is by modifying the work stealing method in a way that makes the distribution of calculation work happen in a more efficient way , which will lead to calculations performed faster than before.Two different modifications of the work stealing method were tested and it led to two new methods, Method 1 and Method 2, which distributed the calculation work differently. Method 1 did not give results that were compatible with the theory, since the calculation time with this method was much longer than the previous method.

Tätskikt i klimatskal : En studie av byggentreprenörers arbetssätt

As energy prices skyrocket and the environmental issues become more frequently debated, interest in energy-efficient buildings has increased sharply in the past decade. Because of this, the interest to achieve high air tightness in building envelopes have once again awakened, due to a good air tightness contributes to lower energy consumption in several ways and to a healthier indoor environment.As the regulations for energy consumption and controls of achieved air tightness has tightened considerably in recent years, the work regarding sheets for air tightness changed significantly for construction contractors. This thesis includes a study that aims to detect what kind of manuals, recommendations or instructions contractors working according, and how a number of randomly selected construction companies in Halland, Sweden, are dealing with the matter of high air tightness of the building envelopes. The study also includes a knowledge inventory of supervisors, site managers and skilled workers, and what their opinions and attitudes are like towards work regarding the sheets of air tightness. The results have been compared with a similar survey dated to 2004, conducted by the SP Technical Research Institute of Sweden in collaboration with Chalmers University of Technology.

Varumärkesrätten inom EU : - ensamrätten i konflikt med EG: s konkurrensregler och reglerna om fri rörlighet för varor

The single market is one of the underlying ideas of the European Union. Free movement of goods and efficient competition are central for the function of the union and are therefore carefully protected by the Treaty of Rome. Exclusive rights of trademarks in the EU can be seen as a method of dividing the common market, preventing the free movement of goods and to be anti-competitive. What comes out of this is that there is a conflict between exclusive rights of trademarks and the rules of both free movement of goods and competition. The aim of this work is to see in which kind of situations the exclusive rights of trademarks can be a part of this conflict but also to study how this problem is resolved by the European Court.

Mastcellsfunktionen vid pyometra hos hund

Pyometra, chronic purulent metritis in metoestrus, is a common disease in intact bitches. About 25% of all bitches in Sweden have contracted the disease before ten years of age. Clinical signs of the disease are varied, and the course may be either slow or acute. The diagnosis is most commonly made by radiographical or ultrasonographical examination of the abdomen in combination with blood biochemical and hematological analyses. The safest and most efficient treatment of pyometra is surgical ovariohysterectomy.There is room for improvement of both diagnostic tools and possible prognostic indicators for pyometra.Mast cells are large leucocytes, with granule that contain inflammatory mediators.

The Price Phenomenon of Equity Issues-A Study on Initial Public Offerings and Seasoned Equity Offerings-

The purpose of this thesis is to investigate the price effect on the initial day of trading of IPOs and the price effect on the announcement day of SEOs on Stockholm Stock Exchange. A second purpose it to conduct studies on which factors influencing the price effects and if these factors can be explained by the same fundamental ideas. Theories regarding capital structure and the pricing of IPOs and SEOs are covered. The capital structure theories involve; Miller and Modigliani's cost of captial theory, Static Tradeoff Model and the Pecking Order. The Efficient Market Hypothesis is presented and previous theories are investigated.

Urbaniserad hästhållning: stadsnära hästgårdar och planering

As the number of inhabitants increases, the cities expand into the former rural landscape. The urbanization causes changes to the functioning of the peri-urban fringe. Land that previously was used for agricultural production is now used for alternative enterprises, as for example horse keeping and recreation. 75 % of all horses (approx. 200 000) are situated in the peri-urban fringe.

Kylbehovet hos ett batteribaserat elenergilager : Med avseende på kyldistribution, drifttemperatur, klimat, isolering och termisk tröghet

Under 2011 började MacBat AB ta fram ett elenergilager kallat Macbat Energy Storage System (MESS), vilket är uppbyggt av 360 stycken tvåvolts bly-syrabatterier inhysta i ett 20 fots container. Då bly-syrabatterier är känsliga för värme är den här studien inriktad på att utreda hur stort kylbehovet blir under olika förutsättningar där kyldistribution, drifttemperatur på batterierna, klimat, isolering och termiska tröghet är varierande parameterar. Det ska även avgöras vilken konfiguration av kyldistribution och isolering som ger lägst kylbehov för de studerade klimaten, vilka är av varmtempererad, arid och tropisk karaktär.För att besvara studiens två mål togs fyra matematiska modeller fram i SIMULINK. Två luftkylda och två vattenkylda där en av varje var isolerad med 100 mm mineralull medan den andra var oisolerad. För samtliga modeller varierades drifttemperaturen mellan 25 ? 35 °C och de studerade klimaten utgjordes av Phnom Phen, Kambodja, Djibouti, Djibouti, Bagdad, Irak samt London, England.

Konvertibla Lån på den Svenska Marknaden: En studie av sex konvertibelemissioner

Issuing convertible bonds for financing purposes has never become widespread practice amongst Swedish companies, in spite of the instrument being common in international markets. Economic theory based on efficient markets suggests that companies should gain no financial benefits from using convertibles and the Swedish situation could be interpreted as in line with this reasoning. However, there are Swedish companies that have chosen to issue convertibles and the Swedish market therefore seems both supportive and contradictory to the existence of benefits of convertible bond financing. Little research concerning the Swedish market has been conducted and the purpose of this explorative thesis is thus to enhance the understanding of the Swedish market for convertibles. This is achieved by conducting in-depth interviews with six listed Swedish companies that have recently issued convertible bonds.

Synen på värdering av Itsystem. En kvalitativ studie av IT-investeringar i fyra kommuner i Västra Götaland

When a municipality is about to realize an IT investment, e.g. an economy system, theywill need to do procurement according to the laws of procurements. To perform suchprocurement takes time and energy from the everyday work at the municipalities, andtherefore they want to make a quick and efficient procurement. Unfortunately it showsthat municipalities do not always make an assessment that is sufficient enough for theirneeds, which can result in an inefficient system in a longer perspective. Municipalitiesthink more often about the hard values such as costs of the investments, and not alwaysas much when it comes to the soft values, like the user-friendliness.
