In this study the spawning migration activity, habitat choice (depth and temperature), foraging activity, duration of stay in the spawning site and homing-behavior was studied for anadromous pike (Esox lucius) in the wetland Österby myr, Gotland.The spawning migration was concentrated to dusk and dawn, a homing behavior was confirmed and there was no significant difference between sexes with respect to duration of stay. A difference in habitat choice and small variation in foraging activity between individuals was established..

På vilket sätt kan konst var ett sätt att locka människor till att besöka naturen? Kring denna fråga, sett ur ett landskapsarkitektperspektiv, kretsar det här examensarbetet. Uppsatsen inleds med en litteraturstudie där avsikten är att få en djupare förståelse om begrepp såsom landskapsarkitektur, konst, natur och Land Art. Även vårt behov av naturen och teorier om att fånga platsens själ behandlas. Härpå följer intervjuer med personer som genom sin yrkesroll och erfarenheter är kopplade till mötet mellan konst och natur.

This study concerns a selection of prehistoric metal objects of animalistic design, published at the internet site of the Swedish Statens Historiska Museum. It seeks to give an impression of the design elements used, and to find likely models for the motifs among live animals. The method used is a qualitative hermenuetic comparative study of objects, where the distinct significant design elements are being identified and interpretated. Several significant design elements are identified, and some are interpretated as representing certain animals. The amalgamation of differentiating design elements in some objects however, leads to interpretations of compound animal motifs, where some motifs are considered ambiguous and some are rendered uninterpretated.

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

The report begins with a general inventory of possible technical faults in a hydropower plant and of possible fault indicating measurements. Then an investigation is made concerning a few different faults. Based on this investigation a choice on seal box condition and water leakage is made as problem for a more thorough examination, in which it is concluded that the turbine water leakage is larger when the turbine is put into operation. The examination ultimately results in a computer alarm for faults related to the seal box. Finally a few things are mentioned about flow measurement and pressure measurement in relation to the project as a whole..

Background: Commerce over the Internet has exploded in recent years. For many companies it has become a necessity to offer their products overthe Internet. This new market ought to change the conditions for relations between customers and suppliers. Purpose: Our aim is to describe and analyse the factors that influence the relations between customers and suppliers, from a customer view, when commerce is conducted over the Internet.Delimitations: The study is limited to B2B commerce with IT-products. Methodology: The thesis is based on a study of the company IMS, their e-commerce site and organisations that buy IT-products over the Internet.Conclusion: Internet opens up new possibilities for custom designed offers.

The purpouse of this study is to find out how and if a Content Managment System (CMS) can benefit from applied User Experience Design (UX). A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it..

During the autumn of 2007 I attended a course in plantcomposition in Alnarp. The main task during the coursewas to make a proposal for a theme garden that was goingto represent the school at an exhibition in the GardenSociety in Göteborg, during the summer of 2008. Thetheme for the garden was set to ?sustainable development?and we had fully two weeks to work with the proposal.I won the competition and during the spring andsummer of 2008 I developed and realized my idea. Thegarden exhibition was inaugurated the 28th of June andwas open until the 28th of September.

The number of elderly in Sweden is increasing due to improved living conditions and better medical care. It is important that society adapts to the increase and begins to work preventively to reduce the costs of the increase. An important aspect is the elderly accommodation, the cost of health care in specific accommodation is almost twice as high as those for ordinary housing. Therefore, it is important that we availability adapt dwelling to allow older people to live in ordinary housing for as long as they wish, instead of moving to assisted living before they need it. If we can fulfil the elder?s needs with home care instead, society can save a lot of money.In this report, three different forms of housing has undergone accessibility increases and been inventoried and analysed.

Augmented reality is a technology thatcombines the perception and interaction ofvirtual objects with the real world. Itcan allow a user to visually see computergenerated models and informationinteracting with the real world through ahand held device such as a tabletcomputer. This opens up a range ofpossibilities, especially in theconstruction sector. A construction siteis permanently changing and the need forprecise and updated information iscrucial. The ability to enhance the realworld with virtual objects and informationmay make many plans printed on paperabsolete.This report describes how workers in theconstruction sector would benefit fromusing augmented reality on a tablet innumerous situations and the technologyneeded to achieve AR on a tablet.

In several countries that have been early in the development of wind farms, there is today a second hand market for the used wind turbines. The European Union (EU) has established a waste hierarchy in order to minimize throwaway mentality. The second hand market is a part of this as the steps are to minimize, reuse, recycle, extract energy and landfill.In order to promote the development of renewable energy, there are energy certificates for the producers that provide it, wind power being one type of renewable energy. After 15 years the energy certificates for a specific wind turbine are no longer paid, and after that there are several different scenarios for the wind turbine. The scenarios investigated in this bachelor?s thesis are export of the wind turbine to countries that are not as far along as Sweden in their development towards renewable energy, selling in Sweden to individuals, and recycling of the wind turbine, as it mostly consists of metals and therefore is recyclable.
