When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.

This thesis has been carried out onbehalf of Lindborg & Sons in Örsundsbroand is a concluding part of the Bachelorof Science program in ConstructionEngineering at Uppsala University. Theaim of the project is to make a plea fora database of good examples of themachine room types using Revit drawingprogram, and work out a correspondingworksheet .At the start of the process it becameapparent that there were somedifficulties in using Revit to creatingmachine room types of the variety whichthe company builds. For modelling ofoblique, curved and irregular lines, Ihad to use my AutoCAD Architecture andthen import them into Revit.The creation of calculus in Excel wastime consuming. On the other hand, it isa one-time work to create the template.The advantage of Excel is that there isno need for a re-calculation at the costof various types of machine hall. Allthat is needed is to replace the variousparameters.

Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.

Denna rapport analyserar ekosläckning för en full duplex högtalartelefon. Systemet bygger på en LMS-algoritm som har implementerats på en TMS320C3 1 signalprocessor. Arbetet har gått ut på att undertrycka ekon genom utnyttja så mycket som möjligt av processoms kapacitet. Möjligheterna för att två eller fler personer skall kunna tala med varandra på att ledigt sätt genom en högtalartelefon påverkas mycket av de ekon som finns i systemet. Högtalartelefonens mikrofon fångar upp ljudet ifrån sin egen högtalare och skickar detta ljud tillbaka genom telefonnätet.

In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential. The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.

Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils. The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.

The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.

During the 1970?s the interest for quality management and the concept of quality costs increased considerably. Business leaders noticed that there was a great potential for reducing costs of poor quality. Since up to 10-30% of a company?s total turnover may consist of poor quality costs some consider them as an unexploited goldmine.

The purpose of this report is to survey Swedex AB?s production costs and to gather all info into a manageable calculation tool. This was made by time and motion studies, interviews of the personnel. All factors were gathered into an Excel chart.The calculation was made according to an additional-charge-method that was considered to satisfy Swedex AB?s goal.

Vid rening av avloppsvatten använder man ofta olika typer av fällningskemikalier för att rena vattnet på bland annat fosfor. Innan man definitivt väljer fällningskemikalie bör man alltid genomföra fällningsförsök för att fastställa om man kan uppå önskade resultat. Helst ska kemikalieåtgång och kostnad bli så låga som möjligt. Efter småskaleförsöken är det även bra att testa i full skala för att se om de resultat som uppnåtts i labbet även uppnås i reningsverket. Rosviks reningsverk är ett av många små reningsverk i Piteå kommun och är dimensionerat för att ta emot avloppsvatten från ungefär 2 100 personer.

In order for construction projects to be completed within the specified time limit while at the same time be financially sustainable it requires thorough preparation and an extensive planning. Most essential is the groundwork and the design that determines the project's progress. There are many aspects to consider in order to avoid inconveniences such as delay, litigation, unexpected cost etcetera. If mistakes are made in an early stage it is very likely that the error will follow the process and become an expensive correction cost towards the later part of the project. In other words, it is expensive to rectify defects later on.

Title: Besparingar inom Barn- och utbildningsnämnden.Seminar date: 29th of May 2009Course: Degree thesis in Business Administration, bachelor thesisAuthors: Amela Smajlovic and Sten SundfeltAdvisor: Leif HolmbergPurpose: Our purpose is to explain the cost-saving process that many municipality organisations face because of the global financial crisis.Limitations: We have limited our study to the municipality of Landskrona and Kristianstad.Method: Our study has a qualitative approach. By using open interviews we have been able to get an open dialog with our respondents.Theory: We have compared with different theories, such as Rombach?s budget-theory and Wildavsky?s role theory.Empirics: The material is based on interviews and conversations with key figures in different levels of the organisations in Landskrona and Kristianstad.Conclusions: The success of a cost-saving process depends on the engagement, awareness and how inclined to changes the persons in the organisations are. Has everybody the willingness to take responsibility fore the organisation and the changes that the surrounding world claims?.

This project was a collaboration with Kajsa Bergström. The projected was to develop the French/English deck of cards. We replaced the knight, queen and king with the numbers 11, 12 and 13. We worked with separate aesthetics and solutions after making that common change. I worked on an idea on how to make the cards look slim, by adapting a handcrafted look, full of details.

Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.
