Unmanned aerial vehicles (UAV?s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV?s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries.

The purpose of this study is to find out how libraries can be user-friendly to people with dyslexia by focusing on how adult dyslectics experience the library. Data were collected through literature and interviews with adult dyslectic students. Two different types of user studies served as a theoretical framework; one was an individual-related study by professor Wilson and the other was a system-related one from professor Buckland. The findings in this study shows that dyslectic library users often experience difficulties when seeking for materials in the library, due to the libraries organisation of material according to the written language. Through technical aid and a more user-friendly organisation of materials it may be easier to find relevant material for dyslectics.

An energy calculation model for Swedish houses   that is fast, flexible and user-friendly has been developed within the   framework of this thesis.  The model   also provides a set of actions which may be investigated in the model based   on savings and payback period. Energy use in a house depends on the technical   conditions, such as building envelope and heating systems, which outdoor   climate the house is exposed to and who lives in the house. Energy use for a   house can be divided into heating, hot water and household electricity. There   are several methods to calculate the energy use of a house. This report   summarizes the methods that may be suitable for a fast and user-friendly   calculation model.

This report is written for a consultant networking company with the purpose to review the development ofthe company's remote connections from a user friendly and security perspective.This includes an investigation of the possibilities to consolidate existing authentication methods foraccessing customers. The problem lies in the amount of methods being used. Through case study wefound that smart cards, SMS-service, software and hardware tokens exist.The only method feasible from a security perspective is smart cards. Since the method is not commonlyused by the company's customers a standardization of it would be counterproductive.Also, the purpose of this report is to investigate how the ongoing internal development of the remoteconnection will affect the company's clients. Within this framework we have also verified a designsuggestion.We interpret, after the completion of the case study, that the internal development of the remoteconnection is marginally affected by legal perspectives.

The energy that the earth receives from the sun hourly has potential to cover a year?s energy demand in the world. Further, this type of energy is environmentally friendly, natural and free of cost. This report covers solar energy in an urban environment and consists of a case study of installations of photovoltaic cells in a part of the city of Stockholm. It is mainly the economic aspects that are covered but there is also a discussion about the practical consequences and the sustainability as a result of integration of solar energy in an urban environment. The aim of the study is to present results from economic calculations for utilization of solar energy in chosen buildings in Kungsholmen in Stockholm.

The report describes an ecodesign thesis performed by the author at the ÅF EcoDesign Center. The basic idea of ecodesign is to develop products with a minimized environmental load, without neglecting other significant product aspects such as function and price. During the last couple of years the public interest in environmental friendly products has increased, which has made it possible for companies to make a profit from their investments in ecodesign. To meet the increasing market for ecodesign services ÅF started the ÅF EcoDesign Center, where the company has gathered all of their competence in ecodesign in order to help companies to become greener. The task was to develop a tool for an Eco Screening.

Att köra eller inte köra is a qualitative study aiming to show how environmentally conscious people who utilizes cars deal with their dissonant behavior, but at the sametime maintain an identity as environmentally conscious. The study is based on the fact that a third of those who drive cars in the municipality of Växjö would like to decrease their use of cars while at the same time having the infrastructural conditions to utilize other means of transportation. The study investigates inner obstacles in the form of habits and lifestyle, but also the different strategies the motorists use to reduce their cognitive dissonance and maintain a green identity. The indicators show that the reason the majority of the motorists continue to utilize cars is part due to inner obstacles (it's adeeply rooted habit, but also a big part of their lifestyles), part due to that the individuals have defenses for their use of their cars, defenses designed to have a dissonance reducing effect. The indicators also show that the motorists value their family higher than the environment, and in this way they can legitimize many of their car uses.

Bacteria are a problem that occurs naturally in dishwashers when the dish stands there dirty for an extended period of time. To get rid of the unpleasant smell that the bacteria is causing, the most common solution is to run a regular washingcycle which can cause problems for the environmentally-conscious consumers since this causes unnecessary energy waste and emissions of chemicals in the washwater. To solve the problem in a more environmentally-friendly way by directly attacking the bacteria with an appropriate bacterialreductionmethod can therefore be an attractive feature in a dishwasher. There are many different ways to treat surfaces that have been exposed to the bacteria. Some high-profile methods are UV-radiation, microwaves and oxidant (ozone) that all three have had success in reducing bacteria in different contexts.

User friendly and usable are two words that are often mentioned in the context of marketing new products. By doing so it adds an extra sense of quality to the product. The meaning of these words is therefore something that every product wants. But what is it that makes a product usable and user friendly? What methodology exists formaking sure that a product is usable? Does it exist applicable processes to ensure user centered development? These questions together with a practical example are parts of what will be addressed in this report.The thesis was carried out for C2 Management, a company that works with supporting other companies in their work with quality and constant improvements.

About 30 % of our greenhouse gas admission comes from the food we are eating, and food plays a crucial role in the choice of destinations. The tourism industry has a great opportunity to affect our food habits. Used in the right way, the industry can teach us to eat more environmental friendly..

There have been several projects with solar installations in Sweden, and Sala-Heby Energi (SHE) wanted to create a solar plant. The question answered in this thesis is whether it is economically viable to create such a source of sustainable, renewable energy. The plant would be built with the help of the financial effort from 120 customers. This economic union would sell the electricity to the SHE, for SEK 4.50 per kWh up to a certain level over a period of 10 years. It would be a long term commitment to environmentally friendly electricity, using solar cells which convert sunlight directly into electricity.In year 2009 there was introduced a new state aid for photovoltaic systems, to create an increased and continuing interest in solar cells.
