n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.

Syfte: Vi ämnar med uppsatsen att undersöka om det råder en skillnad i avkastning mellan portföljer indelade efter kriterier som kännetecknar värde samt tillväxtaktier. Studien genomförs specifikt på svenska marknaden och portföljernas avkastning skall utvärderas utifrån en årlig buy and hold strategi. Vi ämnar även utvärdera om något av urvalskriterierna (Price to book, Price to earnings och Dividend yield) i de polära strategierna är mer framgångsrikt än de andra under perioden 1996 till 2007 ochvilken/vilka faktorer som kan vara avgörande för framgången..

The Swedish oligopoly system that prevailed within the provision-industry has during the latest years subsided. The competition on the market has increased when new participants were given the opportunity to enter the Swedish market. Today the provision-industry is characterized by different foreign participants. Among these new participants one can find Lidl and Netto, who have entered the market enable to provide the Swedish people with an inexpensive range of products. In pace with the growing rivalry the benefits favor the consumers whom are being given several options to choose between.

The study has shown that retailers in the mid-price segment differentiate their brand through developing a strong company identity around the brand. The personality involves store atmosphere, merchandise and advertising. Larger companies have chosen to lay the responsibility on management level, which facilitates on store level. By controlling the strategies on a central level the company can make sure that the stores are steered in the direction that the company wants them to be steered in, and also that they follow the positioning-concept. The company can also devote its efforts to working with its core value, which is service.

In this study a multiple linear regression was carried out in the interest of analysing a number of variables effect on the final prices of apartments in Stockholm?s inner districts. The result may be employed to predict and observe percentage changes on the final price of apartments in Stockholm in the future. Five models were constructed after which they were analysed and compared. The construction of these models were supported by data from the real estate agency Erik Olsson.

The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.

Parallel import in the European Union is the perfectly legal activity under Art. 28-30 EC of buying goods in a low-price country in order to ship and sell them in a high-price country. The pharmaceutical market in Europe is subject to the subsidiartiy principle of Art. 5 EC and heavily characterised by national regulations that lead to significant price differentials between – generally speaking – Northern and Southern Europe. This incites the activity of parallel traders in the first place, who act as arbitrageurs.

This report deals with issues related to construction waste. Building material that has not been built into the project is defined as construction waste. Cost of construction waste amounts to 4-12 % of the total cost of the project. Moreover, cost of construction waste is 1-3 % of the production cost. The aim of this study is to increase knowledge about the main causes of waste within the construction industry.

The Swedish market for unsecured loans has frequently been attacked by media and government officials. Some actors have been accused of exploiting customers and charging inappropriately high interest rates. Despite the public interest very little academic work has been published on the topic. Therefore it is our purpose to investigate why the prices can differ so much between the different actors. Further, we also aim to conduct a market overview as a secondary purpose which will help us in reaching our primary purpose.

This paper analyses the pricing on spare parts. Empirical studies have showed that manufacturers of durable goods make an unproportional large profit on its spare parts in relation to the revenue it generates. It is first showed that according to the standard economic model the price on spare part ought to be zero since the producer include an insurance in the price of the main good. Further it is showed that moral hazard alone do not explain the pricing found in the studies. Finally an analysis of whether consumers with present-biased preferences could be a possible explanation is made.

This study treats the possibility of breeding mallards and pheasants on our own farm, Björnslund. From the beginning I considered to breed them from eggs to adults but after visiting several breeders I changed my mind. It seemed to be a lot of work with no economic profit in comparison with buying already hatched birds and then feed them to adults. If the business shall be profitable I have to be soll the hunting for the birds and then sell the dead birds to game purchasers. There are also calculations that show which price you have to charge for the hunting that will give a positive result. Another possibility is to own a slaughterhouse and sell the meat to restaurants and supermarkets.

Great care and knowledge are required to assess the values of public parks. Many aspects have to be considered to make the assessments reliable and credible. Care and respect for the site and its users are necessary parts of such an assessment. Stockholm City Museum releases in 2011 a document which describes a new system for assessing the cultural historical value of parks and green areas in Stockholm, a city with a great development pressure. In order to evaluate the public realm basic knowledge about the sites? history is needed. Three different parks in Stockholm have been investigated.

This work consists of two studies. One is based on an inquiery to nurseries with production of woody plants, and the other on visits to gardencenters, primarily in Skåne but also in Stockholm. Inquieries where sent to 87 nurseries, 48 of them replied. The purpous of the inquiery was to make a thorough investigation of the ligneous production at the Swedish nurseries, what is produced and in what quantities. Within the inquiery was also a thorough look at the fruit tree production. This to be able to conclude what cultivars that are produced and how large part of that production that is certified according to the Swedish Board of Agriculture (SJV).

Trade is important for every country in the world. Commodities are transported between rich and poor countries everyday. Some of the trading partners are EU and Ethiopia, this because of less expensive commodities from EU than they are in Ethiopia. The most important agricultural commodity is wheat. Ethiopia is a poor country, whose inhabitants mostly are living on agriculture.
