Simulation of rattan harvests in Indonesia : different harvesting pressures and the resulting patterns
The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To
answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.
Den fysiska miljön och skapandet av tjänstekvalitet hos frisörföretag
This paper exemplifies how the physical environment affects clients? experienced service quality and how companies work with the physical environment. In the empiric study, we conducted a case study and studied two hairdressing saloons. The study showed a connection between physical environment and experienced service quality in the business of hairdressing. Owners of hairdressing saloons perceive that a combination of the personal meeting and the physical environment influence the clients? general impression and their experience of quality.
Framtagning av reläskyddsinställningar för en transformatorstation
A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.
Ljudreducering av värmepump
This degree project handles acoustic measurements of the heat pump EcoAir 107, made by Enertech CTC AB. The sound from the three sound sources of the heat pump, fan, compressor and four way valve, have been measured to find out how they affect the total sound level of the product.Measures to attenuate the sound level have been developed and tested. By comparing these with the sound of the heat pump, in its original state, we have found out the measures which have best effects.The best attenuating measures came to be: taped openings and holes around the compressor space, isolating the top and the bottom of the whole construction, support of the fan bottom part and shielding of the sound source with a screen at a distance of 110 mmThese measures have been tested together and an average attenuation of the total sound level with 3,9 dB have been accomplished. In the front of the fan where the continuous sound is the strongest, the attenuation was 4,7 dB.This project is meant to be used as a guide by Enertech CTC AB:s during their future developing process..
Allt är möjligt hus i Gustavsberg
In a sequence described in the next paragraphs, I remove the poorly insulated roof of Gustavsberg Porcelain Factory and make new use of its foundation. The monolith cement slab, once supporting heavy industrial machinery, is now the site of lakes and other movements:The top floor area is split, and a new built volume, one story higher, overtakes the southern half resting on the factory?s basement, digging into it at its western and eastern ends. Striking horizontally, the fissure exposes a long central axis, taking advantage of the factory?s horizontality to articulate vastness .

In the current situation is the straight tube cutter, that provides Luvata?s line of large recoolers with copper tubes, manually operated. To prevent damages and facilitate mounting the tubes must be properly arranged when they leave the machine. This report aims to investigate and present an automated solution where the operator does not need to participate in the process. A number of theories have been drawn up and tests have been done.
Energioptimering : Resteffektkylning av mellanlager för använt kärnbränsle (CLAB) Oskarshamn
This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.
Aktivitetsbaserade kontor : En studie kring hur Vasakronan implementerat det aktivitetsbaserade kontoret och arbetssättet
Partnering is a collaboration method where the contractor and the client work together, based on a mutual trust towards each other and with a common goal for the project. The method originates from the United States where it was early adapted by the U.S. Army Corps of Engineers. It later spread internationally where the United Kingdom and Denmark were early in Europe to see the potential with partnering, to help aid with the issues they were having where construction projects kept running late, going over budget and lacked in quality. By using partnering you can achieve a shorter building time, improved work relationships and enhanced efficiency and cost effectiveness.

Schemaläggning av hissar vid prioritetsanrop : En studie i hantering av prioritetsanrop av hissar på svenska sjukhus vilka styrs av Nearest Car Algorithm
In our modern society, time is important. Technology is used in countless ways to faster get us from one point to another. The purpose of this report is to inquire whether there is a way to implement an option for personnel at Swedish hospitals to claim priority on an elevator call, and to do this in an efficient way. An ordinary elevator system has been simulated with an implementation of textit{Nearest Car algorithm}, an algorithm which calculates the most suitable elevator car to serve a specific call considering the distance between the call floor and the car and the direction. Along with this algorithm, different ways to handle priority calls has been implemented to see how they affect the mean transport time for both passengers with priority and regular passengers in the elevator.
