Hjälpkraftsystem med två lågspänningsnivåer
Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..
Reglering av laborationsprocess med Matlab/Simulink
AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

På uppdrag av Haglöfs ska ett förslag framställas på hur en lansering ska kunna se ut om juniorkollektionen introduceras på den svenska marknaden. Hur fungerar det med produktlanseringens strategiska och taktiska lanseringsbeslut och vilka marknadsföringskanaler är lämpliga vid en produktlansering inom outdoorbranschen.Rapporten behandlar hur dagens företag inom outdoorbranschen i Sverige fullgör sina marknadsaktiviteter vid en produktlansering. Strategiska och taktiska lanseringsbeslut illustreras samt utvalda marknadsföringskanaler skildras.En lanseringsstrategi beskriver de marknadsföringsbeslut som är nödvändiga för att presentera en ny produkt till respektive målgrupp och börja generera en inkomst i form av försäljning av den nya produkten.
Framtida inhemska proteinfodermedel i den ekologiska fjädefäproduktionen :
Organic layers and broilers will according to (EEG) no 2092/91 be fed 100 % organic feeds in year 2012, which is expected to present problems associated with the specific protein requirements of poultry. This document aims at describing the feedstuffs that possibly may constitute a part of the solution to these problems. Peas, field beans, naked oats, canola, hempseed and sunflower come out as interesting feedstuffs. Biproducts from the milling and dairy industry together with marine protein supplements may be brought to the fore, provided that the demand for organic products will rise further..
Utvärdering av traktplanering på Holmen Skog
This study has been performed with the help of forest machine operators in order to improve the forestry planning at Holmen Skog Örnsköldsvik-region.
For Holmen Skog forestry planning is basic for a successful forestry. In a survey I have investigated what can be improved in some areas that are planned for harvesting. The result of the investigation will be used to support the machine operators as much as possible. The study has generated 49.5 % of responses and because of this low response rate, no clear conclusions to anyone else except the responding machine operators can be drawn.
It has been proved that there are some details in the forestry planning system that are inadequate, such as marked routs for trails, tractor paths and buffer zones against streams.
The quality of forestry planning varies greatly between different locations, as much as 50 % of the responding machine operators thought so. Over 40 % of the responding machine operators claim that the information from Holmen is insufficient.
One thing that would improve the forestry planning within Holmen would be to educate all forestry planners and then do continuous follow-ups..
Svält vid akut diarré hos hund, beprövad forskning eller gammal vana?
The idea for this project was initiated together with one of the leaders in the forest, paper and packaging industry. To get through an A/R CDM process the company is exposed to the risk of failing the process or that the overall costs will exceed the benefits of the project. This would delete the incentives to invest in GHG removals compared to purchasing emission allowances on the carbon market. The questions that have been raised and needs clarification in the thesis are the following:? From a company perspective, what are the incentives for implementing Forest Clean Development Mechanism (CDM) projects?? What is a likely financial outcome of a reforestation CDM project on degraded land in the Guangxi province of the Peoples Republic of China?? When does an investment like this break even with the cost of buying market based carbon emission allowances? The objective of this master thesis is to carry out a research about the incentives for forest, paper and packaging companies to invest in reforestation through the clean development mechanism.

Överföring av och beräkning med timmätta värden ? från MT2000 till Xpower
New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.
Hur värderar människor utemiljön och dess funktioner? : två fallstudier - Tarapoto, Peru, och Uppsala, Sverige
This essay discusses people's perception of what is important for their well-being where they live. The main aim has been to find out what factors in the outdoor environments of the city are appreciated and why they are valued positively. A comparison has been made between Uppsala in Sweden and Tarapoto in Peru to see if, and in that case what, differences can be found in the values of people.
I chose to carry out a survey study that got a response rate of 57 persons in Tarapoto and 63 in Uppsala.
The results show that there are some common basic values, but on the whole the outdoor environments are valued differently in the two cities. In short, the Peruvians value functionality, cleanliness, small distances to family and service, while the Swedes value a central location and short distances to friends apart from functionality and good service opportunities. Conceivable reasons for this might be for example different cultural prerequisits, material standard and climate.
