This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

 The luxury market has steadily grown from the industrial revolution and onwards. Changes in society, trends and the increased living standards has enabled more people to consume luxury goods.The world is going through a major economic crisis at the moment. Studies shows that companies that have focused on added value rather than lowering prices has survived past financial crisis. It is also obvious that companies act very different during times of crisis. Adding to the problem is trends that point to a more careful consumption and environmental awareness.

During the past twenty years the immigration to Sweden has changed significantly. Earlier immigration mainly focused at filling the vacancies in the Swedish industry, today immigrants primarily come to Sweden as Refugees. This change of immigration combined with the restructuring of the Swedish industrial sector has resulted in great a deterioration of the chances for immigrants to gain entry to the Swedish labor market.This study aims at examining how the cooperation between authorities in the municipal of Hörby in Sweden fosters integration. The study primarily examines how the cooperation between authorities in a integration project can contribute to a better integration to the labor market.Through a qualitative study, five persons who occupy important roles in the project have been interviewed. The results of these interviews have been complemented by internal documents as well as extern material to validate the results.The most important findings that have been revealed are the importance of language in the process of gaining entrance to the Swedish labor market.

Background: The way in which corporate managers interpret, reason and evaluate uncertainties and constant changes, and how they take advantage of their experiences and wisdom can make a big difference for the long term survival of their companies. The requirements for efficiency and flexibility have increased in many ways, especially concerning the workforce needed and its degree of competency. In Sweden, employee recruiting industry has grown concurrently with the changes in the Swedish economy. Purpose: The purpose is to better understand the recruiting industry by performing a theoretical evaluation from a cognitive perspective. Delimitation: We intended to study the cognitive characteristics of the Swedish recruitment industry.

Vatten är en av jordens livsviktiga resurser, en resurs som hela tiden minskar. I delar av världen råder akut vattenbrist och ofta återfinns industrier med hög vattenanvändning i områden med begränsad vattentillgång. En av dessa industrier är textilindustrin. Vid textil beredning är vattenförbrukningen mycket hög och avloppsvattnet är ofta mycket förorenat. Vattenfrågorna inom textil produktion har fram till idag inte uppmärksammats i lika stor grad som arbetsrätts- och kemikaliefrågorna.

Ämnesintegration är ett sätt att organisera undervisning för att eleven ska se det som förmedlas i ett större perspektiv, i syfte att skapa en helhetssyn på kunskaper, i ett effektivare lärande. Meningen är att elevernas motivation ska öka liksom måluppfyllnaden för undervisningen. Studien har för avsikt att undersöka hur karaktärsämneslärare på Industriprogrammet uppfattar ämnesintegration. Det som undersöks är vilka möjligheter och hinder för ämnesintegration karaktärsämneslärarna uppfattar genom kvalitativa intervjuer med 6st karaktärsämneslärare på Industriprogrammet. Undersökningen kompletteras också med en jämförelse av kärnämneslärares uppfattning om infärgning i en annan studie.

International Marine Group, IMG AB, was established in year 2000, and became the parent company of the three sister companies, Momec AB, Isolamin AB and Premec AB. The IMG ? group supplies complete marine/offshore interior accommodation and tailor-made system supplies to the Building/Industrial sector. With a starting point to develop IMG AB?s logistic and distribution the company has decided to survey the present logistic at their subsidiaries, mainly concentrated on the goods for delivery.

ABB and Prevas have initiated a collaboration to sell a system to optimize steel industry furnaces, called FOCS. The purpose of this thesis is to investigate possibilities for integrating Prevas FOCS and ABB 800xA.The result of the investigation is used for an implementation of a prototype of the integrated system. The study shows a general method that can be used when implementing two software systems. The prototype of the integrated systems is made with usability principles in mind. This is a very important aspect in order to create a good working environment for the operators of a steel plant.

I vår studie har vi kommit fram till att det inte finns någon entydigt och klart svar på våra frågeställningar. Vårt exempelföretag Previa visar och mäter att kundens investering ger effekt genom ett unikt kommunikationsverktyg som heter Hälsoeffekten. Verktyget fungerar så att företagets alla siffror förs in i ett system som ger en överblick av företaget. Previa kan sällan garantera att den önskade effekten av investeringen verkligen uppstår, det vill säga att den kommer företaget till del. Det föreligger vidare ett problem att kunna bevisa att förebyggande insatser kommer att ge effekt, eftersom det ibland inte kan påvisas att problem i framtiden kommer att uppstå och då inte heller åtgärdas.

Swedish biogas is currently produced mainly by anaerobic digestion of sewage sludgeat sewage treatment plants, landfills and anaerobic digestion of household or industrialwaste. Also cattle ma-nure from farms can be used to produce biogas. Upgradingbiogas represents an increase in methane concentration from about 65 % to about 97%. In addition, particles and contaminants must be sepa-rated from the upgradedbiogas. There are various methods for upgrading and this report compares sixdifferent methods with respect to environment and economy: water scrubber,Biosling, cryo technology, chemical absorption, Pressure Swing Adsorption (PSA) andmembrane separation.According to the used ORWARE model, chemical adsorption with amine has the leastenvironmen-tal impact (methane emissions) and the lowest costs.

The demand för Swedish pork meat is increasing every day. This leads to agricultural farming having to develop as an industry, with larger and more rationalised units to make the farming more effective and to raise the financial profit. The consequence of this is that it affects the animals when their surroundings become more industrial. The pig´s natural behaviour becomes restricted by the limitations of the facilities, which leads to them becoming understimulated. Helena Kummel, a teacher at Munkagård upper secondary school and also an educated animal inspector has developed a prototype that could possibly replace the pig´s natural rooting behaviour inside the barn. The porpuse of this report is to study "bökboxen" in the gilts´actual living enviroment, through qualitative- and quantitative analysis.

Detta examensarbete har genomförts på avdelningen Mätteknik & Teknologi (REI) på Siemens Industrial Turbomachinery AB i Finspång. Målet med arbetet var att konstruera och designa en ny utrustning för kalibrering av brännarna till gasturbinen SGT-750. Dagens befintliga utrustning har ett stort kalibreringsbehov och genom att ersätta komponenter i dagens utrustning med nya som är mer optimala för kalibreringen fås bättre mätnoggrannhet, beräkningarna blir enklare och kalibreringsbehovet av utrustningen blir mindre. Därmed skapas en tidsvinst för företaget. Idag används mätsträckor i utrustningen och de kommer i den framtagna utrustningen att ersättas av en massflödesmätare av typ Coriolis.På grund av att examensarbetet är ett delprojekt i ett större projekt som har försenats, mot förväntad tidsplan, så har examensarbetets huvudsakliga innehåll ändrats under projekttiden.

The intention of this final thesis is to look into the improvement of small and run down railway stations. Many railway stations are today derelict and decaying. The purpose of this essay is to propose alternative strategies of action by discussing the ecology, the history and the social function of the railway station. There is also an overview of projects already completed. In the analysis part of the thesis, the genius loci or the spirit of place is put forward as means of reaching a solution.
