This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.

In Sweden the work of reducing acidification and its prime cause; emission and deposition of sulphur dioxide, has been going on for decades. Despite of all the work that has been done the positive progress in the acidified areas is slow. This is partly due to a long recovery time for the acidified areas but also because the reductions of emission and deposition of sulphur dioxide have not been large enough. Emissions of sulphur dioxide from land based source in Sweden are estimated to 34 000 tons in the year of 2010. During the same year, approximately 182 000 tons of sulphur dioxide will be deposited over the Swedish territory.

BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

Buildings worldwide account for 40 % of the total energy use. Climate change is of increasing importance, but few are willing to reduce their standard of living or get a higher cost for the change. Energy efficiency of existing buildings gives the greatest benefit economically and environmentally. The real estate company Klövern AB manages 46 properties in Karlstad. Heating is the major cost of the total operating costs of real estate. Rising energy prices increase the need for Klövern AB to improve energy efficiency and to investigate alternative sources of heat.

The private sewage systems in Sweden releases around 600 tons of phosphorus per year, compared to about 350 tons from municipal sewage treatment plants, and they account for approximately 21% of the total anthropogenic discharge of phosphorus into Swedish waters. About 40% of Sweden's nearly 1 million private sewage systems are inferior with respect to emissions to surface and groundwater. The technology of small sewage plants is under development and knowledge of treatment effects for different solutions is poorly consolidated. Municipal authorities lack resources to keep up with the technologic development and assess the reliability of the treatment performances that suppliers report for their products. The thesis aims to conduct a market review and evaluation of wholly or partially prefabricated small sewage plants, to make it easier for municipalities and property owners to assess different technical solutions. The goal is a compilation of the products on the market, evaluated on the basis of the reliability of specified degrees of reduction.Information on sampling procedures and test results were collected through a questionnaire to all active suppliers and the responses were then used to classify the products.

Uppsatsen a?r skriven fo?r att ta fram ett alternativt sa?tt att ranka lag i olika serier. Vi har lagt sto?rst fokus pa? fotbollsallsvenskan, men a?ven tabellerna i fotbolls-EM, basketligan och elitserien i hockey kommer att ja?mfo?ras. Vi kommer att introducera Perron-Frobenius sats med en kortare beskrivning och fo?rklara hur Google anva?nder satsen genom PageRank fo?r att du ska kunna hitta just den artikel eller hemsida som du letar efter.Senare i uppsatsen beskriver hur vi anva?nder Perron-Frobenius sats fo?r att fa? fram en alternativ ranking till den som anva?nds idag.

This thesis has been performed at BAE Systems Hägglunds, which is located in Örnsköldsvik. Hägglunds has a wide background of engineering, where they have manufactured all from airplanes to lifting cranes. Currently they only produce track vehicles at Hägglunds, where they manufacture the CV90 and BVS10 models. This thesis concerns the BVS10 which is an all-terrain-vehicle. The main purpose with the BVS10 is to enable transportation of material and personnel thru tough terrain.

En hel del av forskning inom kognitiv neurovetenskap tyder pa? att effektivare uppla?gg av repetitionstillfa?llen fo?rba?ttrar inla?rningsprocessen hos eleverna, eller ra?ttare sagt hos ma?nniskor i alla a?ldrar.Uppsatsen handlar om yngre instrumentalelevers inla?rningsprocess i relation till hja?rnans minnesfunktioner och underso?kningen fokuserar fiolundervisning pa? nybo?rjarniva?. Jag har utfo?rt ett empiriskt experiment av tajmade repetitionstillfa?llen via interaktiva onlinebaserade samtal med tre yngre elever.Alla de tre eleverna har under projektens ga?ng a?stadkommit fo?rba?ttringar av de fa?rdigheter som stod i fokus vid de tajmade repetitionerna. Experimentperioden har haft positiv inverkan pa? elevernas motivation, men deras uppna?dda fo?rba?ttringar bedo?mer jag vara av icke besta?ende karakta?r.

Fo?ljande underso?kning handlar om hur la?rare och blivande la?rare ser pa? a?mnet musik och estetiska la?rprocesser i fo?rha?llande till den nya la?roplanen Lgr11. Fokus fo?r underso?kningen ligger pa? de som undervisar eller ska undervisa i ka?rna?mnen det vill sa?ga svenska, engelska eller matematik i grundskolan a?rskurs 3?6. Metoden har varit intervjuer av tre kategorier: la?rare, la?rarstudenter och la?rarutbildare.

Detta arbete inspirerades av Chions (1994) term det audiovisuella kontraktet samt Nørretranders (1993) forskning om medvetandes bandbredd. Problemsta?llningen fo?r detta arbete var: kan man utan uppmaning ho?ra ett ljud som betraktas som ett sva?ruppma?rksammat ljud i en ljudbild som besta?r av ljud som a?r la?ttare att ho?ra, med hja?lp av en bild. Testpersonerna fick lyssna pa? ett ljudklipp som bestod av fem ljud.

In this project forging of aluminum alloy Al 6026 T9 has been performed in the temperature range of 400 °C ? 470 °C. The alloy which was in the shape of a cylindrical billet was formed in a press with the aim of analyzing the effect of different forging temperatures and required press load for optimal die filling. The component?s dimensions were later measured and compared to a reference piece.
