Total organic carbon (TOC) and chemical oxygen demand (COD) are two methods used for measuring organic pollutants in wastewater. Both methods are widely used but the COD method results in production of hazardous wastes, including mercury.The purpose of this study was to validate the method TOC that will replace COD and find a factor to convert TOC to COD. In this study 26 samples were analyzed from four sewage treatment plant in the municipality of Enköping.The results show that the COD method could be replaced by the TOC method.The factor for COD/TOC was between 3.1 - 3.3. Both methods will be used in parallel until 2013 when it will be forbidden to use the COD analysis..

Den här rapporten redovisar produktionsprocessen för en re-design av en webbsida. Kommunikations-byrån Åkesson & Currys webbsida har funnits i över fem år. I dagsläget tycker inte företaget att webbsidan representerar vilka de är, därför var ett led i produktionsprocessen att undersöka hur de ser på sin identitet. Målet var att med en ny vision av Åkesson & Currys identitet producera ett designförslag över en webbsida som presenterar dem på ett representativt sätt. Re-designen ska möjliggöra att användaren blir intresserad av byrån och gärna initierar till en ny kontakt med Åkesson & Curry efter ett besök på webbsidan.

At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.

The company LightLift Esystems AB manufactures patented motorized lift systems for the illumination of halls with high ceilings. The company wants a new design for singular heavy lights in order to be more competitive.This project consists of the development of the new design under the requirements and specifications imposed by the company. The new design must support lights up to 300kg and keep the overall dimensions as low as possible without modifying the driving unit.This document contains all the designing steps followed to reach the final solution as well as the material selection, manufacturing process and assembly of all the parts that form it.The solution obtained shows to be very competitive with other alternative products, since this new design triples their maximum load capacity while the dimensions are very similar.In this context, the optical appearance was also very important to the company and so it was another main objective of this project. From an aesthetical point of view, the final solution proves to be very compact and versatile since it can either be hidden behind a false ceiling or covered by a plastic case that gives the design a very nice look.Finally, the solution achieved fulfils all the requirements and specification previously imposed. It is reliable, compact, cheap to manufacture, easy to assembly and it has a good optical appearance. .

Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

The emergency medical care in Sweden has been under persistent debate, due to factors such as long waiting hours, inefficient patient flow, and understaffed departments. In an effort to meet the critique and with a willingness to improve the problems, an increasing amount of emergency clinics are adopting theories and models within Lean. Positive outcomes are evident, there has been some criticism directed towards Lean. Among these is the argument that in order for Lean to be successful it needs to be used within standardized and foreseeable processes, and that it therefore only is applicable to those kind of processes found within industrial production. This prompted the question of whether Lean was a suitable strategy within emergency medical care, considering the large variation of patients and non-foreseeable processes that in fact share little resemblance to that of industrial production.

This essay is a product of our examination work on candidate level in Interaction Design. The aim in this project was to design a digital wallet integrated into a cellular phone and make it as an electronic payment tool. In our project the goal has been to create a digital wallet not just for payment, but also develop it into a complete digital wallet, replacing visa, membership card, student cards, id card and receipt. Our ambition is to take care of current qualities of today's wallet and improve where it is possible so that can be replaceable with the digital wallet..

This project investigates how team sports can be used to include young women in public space aswell as how through the addition of a sporting facility adjacent to three schools can be used as a stepping stone for the young people of Dharavi to have a chance at a brighter future..

Detta examensarbete är en undersökning i kommunikation genom konst och design.Det är ett gränsöverskridande samarbetsprojekt vars syfte är att skapa en diskussion kring ett fortfarande tabubelagt ämne. Genom ett gestaltande arbete i textila material undersöks hur vi på ett kreativt sätt kan bidra till samhällsdebatten runt övervikt och fetma. Projektet resulterade i två textila verk som gestaltar den nya svenska kroppen. En textil skulptur i form av en överviktig dalahäst och en folkdräkt för den nya svenska kroppen. I vår gestaltning använder vi oss av dalahästen och folkdräkten som symboler för svensken.

This degree project has been carried out in cooperation with Gedevelop in Helsingborg.Gedevelop has developed a camera that can calculate the weight of a liquid glass mass.Because of the density and viscosity changes in the glass, the weight information issometimes incorrect given. Glass industry is today addressing the problem by an operatorperforming a manual weighing of a few bottles which, in turn, calibrates the camera system.The project aimed to develop an automated system to control the weighing of glass bottles forglass industries. This system must be so flexible that it can be easily mounted on plants withdifferent production equipment around the world.The project includes design and construction of equipment that meets the requirementsformulated together with Gedevelop. Work has been done both in Halmstad and Helsingborgand has included both calculations and review of the theory to understand the forces thatinfluence the design of different construction parts. A prototype was produced that meets theoperating requirements for the design and can be used in testing features.

I mitt examensarbete har jag arbetat fram en glaskollektion med tema mens. Målet med mitt arbete var dels att höja mensen ur tabut, dels att ge bruksglaset en ny scen. Genom att göra en menskoppsbehållare i transparent glas vill jag ifrågasätta varför vi gömmer och smusslar med våra mensskydd men också varför mensen idag framställs som oren, äcklig och skamlig. Jag vill uppmuntra till att bryta det mönstret, ge den som menstruerar en möjlighet att hylla mensen, sätta den i fokus, på piedestal. Mitt arbete resulterade i ett mensaltare, en tolkning av hur jag tror mensen hade framställts om vi levt i ett matriarkat.
