Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.

The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. Furthermore, there is a demand on WWTP´s to alter eutrophication in aquatic systems through better nitrogen and phosphorus removal. An increasing number of WWTP´s have acquired biological nitrogen and phos-phorus removal. A by-product of this type of biological treatment is the formation of nitrous oxide, which is a potent greenhouse gas.

Då dagens konflikter ofta utspelar sig mitt ibland civilbefolkningen och där aktörerna kan utgöras av allt från miliser till kriminella gäng ställs det nya krav på de militära förmågorna för att kunna agera i dessa komplexa miljöer. En generell trend för dagens artilleriförband är att de används till att verka mot mindre målgrupper utgörandes av två till fyra personer. Erfarenheter från konflikter i likhet med de i Irak och Afghanistan har visat på vikten av tillgång till precisionsbekämpning med indirekt eld för att undvika förluster bland de civila. En förutsättning för att kunna genomföra precisionbekämpning är att målets position kan lägesbestämmas med en mycket hög noggrannhet.Med hjälp av ett digitalt eldledningsstödssystem innehållandes en tredimensionell digital karta kopplat till EOI:et kan positionsfel i måluttaget i en urban miljö reduceras till under metern. .

This paper is a study of 18 extant pieces of panegyrical music for the Swedish king Karl XI (1655?1697). The compositions are preserved in two forms. There are a few contemporary prints, but the largest amount of music is preserved as manuscripts in the Düben­collection (Uppsala University Library). The paper focuses on four different aspects of the production of these 18 compositions.

A high quality is highly requested in today?s thinnings, since these are the base for continued value development of the forests. Thinning quality often means a minimization of damages on soil, stems and roots during the cutting. One way to reach a high quality is to set up goals that will be followed up after the cutting is made. Self-checking gives information of the machine drivers work and guarantees the customers a good quality of work.

This bachelors thesis was made forWallenius Water AB to develop a basisfor an Airpurifier prototype. Wallenius Water isone of the world's leading environmentaltechnology companies engaged inchemical-free water treatment based onUV-radiation. The thesis aim was toproduce a basis for a prototype that canbe used in three applications:Standalone, RAS systems and ventilationsystems. The work includes anintroductory description of the theorybehind AOP technology based on aliterature review on the subject. Asurvey of products currently on themarket and a product specification hasbeen used as the basis for thepreparation of a number of concepts inthis report.

The purpose of this study is to incrementally, through a combination of various methods, examine the assumptions about the working economic outcomes that can be made based on planned ergonomic intervention in a department at Pfizer Health AB in Strängnäs. The study contributes to knowledge about how assumptions on OSH financial results can be made, based on planned ergonomic interventions. These assumptions were based on biomechanical calculations made on the basis of ergonomics measurements with inclinometer. The study is important because previous research has shown that poor work environment have a bad impact on the economy of a company in different ways. It can for example be negative impact on the company's productivity and quality of the units produced or the services provided.

Att skatta sannolikheter för extrema händelser är svårt eftersom de sällan inträffaroch underlaget att bygga skattningar utifrån är begränsat. Ofta används skattningsmetodergrundade på asymptotiska resultat från extremvärdesteorin som inte självklart äruppfyllda när man utgår från en verklig datamängd. I den här uppsatsen har en sådan metod, som kallas peak over threshold-metoden, jämförts med en modifierad metodsom inte bygger på sådan asymptotik; fastypsmetoden. I peak over threshold-metoden skattas den betingade sannolikheten att befinna sig långt ut i svansen av en fördelning med hjälp av en generaliserad paretofördelning. I fastypsmetoden skattas istället den betingade sannolikheten att befinna sig långt ut i svansen med en fastypsfördelning.

This paper discusses the advantages and disadvantages of using different benchmarking models to measure and compare the efficiency of Swedish gas distributors. It also discusses to which extent the results of a benchmarking study should influence the revenue-cap which will be implemented in the gas distribution sector in Sweden from year 2011. The discussion is based on arguments from both theory and practical applications of benchmarking. The results suggest that benchmarking Swedish gas distributors against distributors in another country using a parametric model is most favorable, but the reliability will be increased if non-parametric models are used also. Partial and total productivity measures could be used to confirm results of other benchmarking analyses.

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

Part 1 of 2  ? Lean philosophy ? five steps to get the workplace in order?Part one deals with the theory of what Lean and 5S are.Lean is a long-term approach that involves a quest to become the best on the market by increasing employee engagement, eliminate waste and focus on the right things.5S is a method of order in a system. Businesses around the world are using these 5S which stands for sort, straighten, shine, standardize and sustain. Part 2 of 2 ?

Instead of search, the workers can do the real work..

The purpose of this study is to illustrate the impact on children's development around playing and how significance the formation of the schoolyards is focusing on how it inspire and calls to play within the children's. The study will also show how the youth workers experience the schoolyards and how they can incorporate the playground in their work to inspire the children's play and activities. The methods used in this study is based on both real conversations and by mail with educated youth workers and observations. The results shows that the schoolyard environment is very important for the children's play and development. The study reveals the importance of having nature like forest nearby and that the environment should be suited for everyone.

This project is a learning CD-ROM production aimed at first-time parents. It is using both sound and images, moving as well as non-moving. The purpose of the production is to be an interesting alternative to traditional books. We have been looking at similar productions like drivers license educational CD-ROMs and encyclopedias for inspiration and ideas on how to proceed. In order to give the content some dynamics, we've also added the element of 3D-animated sequences.

In this master?s thesis real settlements for the over consolidated clay below Arenahallen in Halmstad are compared with two different models for settlement calculations; Chalmersmodellen without creep and Chalmersmodellen with creep. Chalmersmodellen with creep is based on Terzaghi?s consolidation theory with an addition to creep. The purpose has been to find out whether Chalmersmodellen with creep can be used for this clay or if Chalmersmodellen without creep should be used instead.
