This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

The evaluation of the function of the feeding of sheep herds is suggested to involve the work effort, the fulfilment of the nutrient needs of the sheep and the feed waste. Mechanisation of the feeding can be very simple or include high degrees of mechanisation. Three different farms, representing different levels of mechanisation are presented. Descriptions and analysis of the feeding systems including mechanisation, work effort and estimations of the feed waste are made on each farm. The herd with the most advanced feed mechanisation included a rolling feed band and mix wagon. The other farms were partly or little mechanised including ad lib feeding from big bales and manual distribution of hay and concentrates. The most mechanised farm was able to feed a large herd of sheep at a low work effort and little feed waste. However, the investment in machinery has to be weighed against the improved efficiency.

Everyone has to take a greater responsibility in energy issues, both individuals and companies. There have been some major developments in the construction industry but there is still a lot to be done. This diploma work thesis presents different methods of making existing construction shed establishments to use less energy. What is possible to do and how much energy is there to be saved? A shed establishment consisting of 8 shed units were studied in this project and the building simulation tool VIP-Energy was used to simulate different types of material in the sheds. An infrared camera was used to locate thermal bridges. There are several factors that can be improved to make a construction shed establishment to use less energy.

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.

The economic climate that has been going on for the last years has more or less affected everyone. This has created a need to get more knowledge about how our banks work and also how peoples own personal financial situation looks like. When our banks over this last period have compensated their employees with even greater deals of money, reactions has gone to the roof. This discussion has made us interested in the subject, which led to the decision to write an essay about remunerations within banks.The purpose of this essay is to investigate if our banks remunerations to their employees have any effect on their profit numbers. Does the size of the compensations vary with changes in the market? Do larger compensations contribute to a greater result?The study will look at Sweden?s four largest banks, Handelsbanken, SEB, Nordea and Swedbank.

The purpose with this essay is to study police students perception of men?s and women?s role taking and behavior in a group. The question that is presented is if a group?s efficiency can depend on which gender the members of the group have. There are many theories about the concept male and female and the meaning of these words.

Landscape architecture is a visual profession, but other senses also affect our interpretation of a place. Sounds can give us a lot of information about an environment, and they are often perceived as positive. Despite this, research about outdoor sounds most often focus on the reduction of unwanted sounds ? noise ? but the absence of noise does not result in a good soundscape. To accomplish this, sounds we appreciate are needed.

Upplands Väsby municipality has a vision that podcars in the future will become an effective alternative in public transport, with reduced car-dependency as a result. The system would also attract new inhabitants and businesses to the municipality.This report deals with various issues that podcar stations may face. Also, suggestions for possible track laying at the stations and station design are presented. Two areas are investigated. Eds allé which is a neighborhood that is planned for housing and where the station may be planned into the cityscape from the start.

Ad Astra är en cirkushall, högt beläget på en skogsbeklädd kulle ca 10 minuter från Alby centrum. Här samlas hela Cirkus Cirkörs verksamhet under ett tak: elever, lärare, administration och besökare.Promenadvägen från Albys tunnelbana leder fram till ett torg med den nya byggnaden som fond. Ett strikt grid av 58 stålpelare definierar ett uterum på byggnadens tak som sluttar upp mot en kopparkub bland träden. Här skapas möjligheter till allt från utomhusföreställningar till picknick i ett landskap som subtilt smälter samman med den bakomliggande skogen. Gränsen mellan natur och struktur suddas ut samtidigt som taket ger en oöverträffad utsikt över Alby och Albysjön.Internt är byggnaden tvådelad med en publik, öppen del och en sluten,flexibel hallösning.

Shopping malls have been growing in numbers during the last few decades. As an effect, consumers are increasingly placing a greater amount of their purchases under one roof. The problem is that stores within these malls have to fight for the consumers' attention in competition with all the other stores. Thus, making consumers noticing their store is critical for success. Creating attention through floor advertising could be a potential way of doing so.

The degree project was made forZetterbergs Industri AB. The company is market leading in Europe in the heavyvehicle industry, designing and building body systems for trucks.In their line of products is the hook lift called Livab, a flexible and uniqueproduct. The hook lift is often demanded by customers because its special ability tobe able to operate in situations with low roof clearance. The main operation principleof the hook lift can be described as a truck stand, laid down.There are two main versions of the hook lift Livab, AL 26 and AL 32. These are ofdifferent load capacity, 17 and 25 metric tons of gross weight respectively.

Den här rapporten har som syfte att utreda vilket eldistributionssystem för offshoreenheter som sparar mest vikt och utrymme. De två elsystem som jämförs är GVAs standard system och Siemens Blue Drive System. Rapporten innehåller en teoretisk bakgrund för båda systemen och dimensionering av systemens kraftkablar samt beräkning av kabelvikter och komponentvikten för systemen. För att uppskatta kabel- rutter och längder kommer ritningsunderlag för GVAs offshoreenhet 7500 att användas.Resultatet visar att GVAs standard system är det eldistributionssystem som har den lägsta totalvikten med 168 ton, GVAs standard system har en vikt som är 101 ton lägre än Siemens Blue Drive System som har en vikt på är 269 ton. GVAs standard system har en lägre ström vilket gör att ledararean blir mindre och i med det blir kabelvikten mindre.

One of today problem at IVT industries would be assembly of insulation on water cisterns. The element of assembly insulation on the cistern gets too elevated; hence one has to climb onto the stand the cistern is assembly on. This will increase the risk of work related injuries when there is a risk of falling down. It?s also rather strenuous on shoulders due to work with your arms high above your head.

The mistakes and failures on the roof are noticed during inspection of the construction, many of the commentaries are recurring. A contractor should only need to get a commentary once and then learn from the mistake. It has in this study been brought to light that the solution is not to tell the contractors to "stop slattern", it is more complicated than that. Today, the biggest problems are found in leadership, communication, feedback of experience and that the entrepreneurs take too little responsibility.To minimize the amount of commentaries all contractors need to work with a clearer leadership where the leader is both respected and appreciated. The leader must in an effective way be able to convey all the information to all employees.
