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.

Computer programs must give a technical effect that goes beyond"normal physical interaction"to be considered to belong to a technical field. The invention shall be be susceptible of industrial application, which means that it should be possible to reproduce or use in any other industrial way. The reqirement that the invention shall be new means that the technique must not be previously known because of patents, published articles, etc. That an invention shall be a contribution to the state of the art in a technical field means that the invention shall not be obvious to invent for a person skilled in the art. Patents do effect the innovation among the inventers, but in most industries most inventions would be invented independent if there was a patent system or not.

People have utilised and influenced the boreal forest for many centuries. Prior to the industrial revolution during the 19th century, however, human use primarily only had a low impact on the forest. When the timberfrontier swept over the country, the Swedish forests came to change for ever. The study site for this thesis is situated in the northern part of the county of Västerbotten, Sweden, and has previously been a National forest. Today the area is an ecopark and the land is owned by the forest company Sveaskog.

The purpose of this paper is to survey the textile based proto-industrialism in Sweden in the middle of the 19th century. This case study is founded upon Anders Hansson?s pre-industrial textile production at the estate of Mölneby, Östra Frölunda in the rural district of Kind in the province of Västra Götaland.Account books from the year 1853 related to Anders Hansson?s wool fabric manufacturing have been looked into and categorized using a quantitative research method. The research has also been supplemented with a number of interviews.The result of the survey shows that Anders Hansson?s business activities fit into Mendel?s theory of proto-industrialists at a practice level.By collaborating with a merchant in Gothenburg the fabrics were traded in unknown markets, as well as in more familiar neighbouring districts.

Since the 1980's economic policies has become an important issue in municipalities and more resources are put into projects that are intended to have a positive influence on the local economic growth. From a theoretical perspective of regime theory and a model of local political economy, concerning the strategies chosen by the actors involved designed by Jon Pierre, the discussion points to the fact that it is possible to affect the local development. The municipalities discussed and compared in this thesis, Bromölla and Östra Göinge, have similar prerequisite for growth mainly due to their dependence to large industrial companies.In order to fulfill the aim of the thesis and examine the change in economic policies over time and between the two municipalities a comparative method is used. The creation of local governing coalitions is emphasized which makes efforts and intentions of individual actors crucial for the success of the local economic policies. Bromölla started their more active efforts in the area of economic policies earlier than Östra Göinge and has also come a bit further in the process.

I Finspång tillverkas gas och ångturbiner. Verksamheten går under namnet Siemens Industrial Turbomachinery AB, som förutom att bygga upp turbiner som separata leveranser även projekterar kompletta kraftanläggningar, där turbinerna ingår, för att producera elektricitet, ånga och värme.Till de gasturbin kraftverk som levereras av Siemens Industrial Turbomachinery AB används ett Simatic PCS-7 styrsystem för att kontrollera turbinerna. För PCS-7 styrsystemet kan mjukvaran Simatic PDM (Process Device Manager) användas för diagnostisk analys av automations komponenter och intelligenta fältenheter. Målet med examensarbetet är att kunna varna tidigare för fel på automations komponenter och fältenheter så att man kan förebygga stillestånds tider som kan uppstå i en anläggning. Examensarbetet visar vad för slags funktioner Simatic PDM har och hur programmet kan utnyttjas i en anläggning.Examensarbetet innehåller en beskrivning av programmet Simatic PDM och PCS 7-styrsystemet.

Vi har genomföret ett antal intervjuer i fallföretagen samt en expertintervju.

In modern industrial robots the components in the transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly within the field of iterative parameter estimation.This thesis considers recursive grey-box identification for a nonlinear model of the transmission in an industrial robot. The nonlinearities that are identified are friction, spring stiffnes, hysteresis and backlash. These nonlinearities are a part of the models that are presented in this thesis.

Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants. When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.

The access to good sanitary facilities is an important factor that elevates the experienced living standard as it improves hygiene and reduces the transmission of deseases. The ratification of the millennium goals by 189 countries demonstrates that this is an important international issue. Together the countries have taken upon themselves that the proportion of the population that lacked access to sustainable safe drinking water and sanitary facilities in the year 2000 will have been reduced by half by the year 2015. In Peru, the construction of sewage pipe networks to transport the sewage out of the direct human environment is progressing. The safety and sustainability of these systems can be questioned, since in Peru the sewage seldom receive any treatment before being emitted to a recipient. This is taking place in Picota and sorrunding villages as well. In the last 25 years several systems implementing small-scale onsite treatment have been introduced throughout Latin America in an attempt to give more people access to sustainable and safe sanitary facilities, reducing water consumption and taking advantage of the agricultural values of the sewage fractions while protecting the environment from its negative impact. In this study three different sanitary systems and the effects of different population growths were compared.

A group of companies that only recently has caught the attention of Swedish designers, enterprises and media are the so -called "furniture pirates". In Sweden it?s mainly two companies that have ended up in the spotlight. The online stores Ikon M and Designers Revolt are two companies which currently sell replicas of famous Swedish and foreign designers. Although the designs sold are copyright protected in Sweden, and most other European countries, the right holders can only stand by and watch as more or less exact copies are sold for a fraction of the price of the originals.The business model - to exploit the EU?s free movement of goods and the UK's short term of copyright protection in matter of mass-produced art (industrial design) - has proven successful for the companies that practice it.

During the period 1952-2008, real prices of wood before taxes and charges declined. However, the actual net income has not changed by the same percentage as the price list, because taxation, driving costs and the ability to make deductions has changed. This report considers the inflation by using the Swedish consumer price index. Net income refers to the remaining income when relevant costs, taxes and fees have been paid.The purpose of this study was to examine how the private forest owner's real net income has evolved over the period 1952-2008 for three categories of forest owners. These three categories are1.
