Livscykelbaserad miljövärdering av en ny kontorsbyggnad : En jämförande studie mellan två analysmetoder
This Master?s Thesis aims to illustrate in what ways the two Swedish environmental assessment tools, the Environmental Load Profile and EcoEffect differ and if performed valuations gives different results and environmental goals.The built urban environment causes about half the environmental loading in Sweden. The society?s ambition towards sustainable development has resulted in demands reducing the environmental load. One way to accomplish this change is with the assistance of tools for environmental assessment of the built environment.
Verifiering av Kedertakstolen
The Kedertruss is the loadbearing part in the Keder weatherprotectionsystem and it has been analyzed concerning its loadbearing capacity. The Kedertruss is produced and manufactured by Wilhelm Layher GmbH & Co. KG and this report has been made for their Swedish division Layher AB. The Kedertruss, designed in Germany according to German designcode, has been recalculated concerning Swedish conditions according to Eurocodes and a ongoing European standardization project. The two-dimensional program Winstatik Frame Analysis has been used for evaluation of load effects. Capacity has been calculated by hand-calculations and it has been verified that the Kedertruss in its larger spans isn?t able to withstand the loads.

With the elevated oil prices of today it is necessary to look for other heating alternatives. If the oil price continues to develop in the same way it has done the last years it will soon be impossible for many producing garden companies to survive.
The purpose of this diploma work is to compare three different fuel options in order to find the most economic one considering the conditions of Katrinebergs Handelsträdgård AB.
In relation to oil it is profitable to change to any of the three alternatives: wood chips, wood pellets and grain. The most profitable option is to change to wood chips. This alternative has a payoff time less than three years and after that the annual saving compared to the oil is relatively high. The annual cost is 65 % of the cost of the oil alternative.
Analys av designalternativ för snabbare dynamik i kolkraftverk med koldioxidavskiljning
Combustion of fossil fuels is today the dominating source of energy. During combustion,carbon dioxide is formed. The carbon dioxide accumulates in the atmosphere,which raises the global average temperature on earth through the so called greenhouseeffect. The only way to reduce the emissions of carbon dioxide from combustionin a coal fired power plant is through carbon capture and storage (CCS).Post-combustion capture is a technology to separate carbon dioxide from the uegas after the combustion for efficient transport and storage. The steady state operationof coal fired power plants with post combustion capture has already beenthoroughly investigated on a pilot scale, however much work remains to investigatethe plants dynamic operation.

TOMO Hugglink
Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.
Tillämpning av nya beräkningsmetoder för branddimensionering av träkonstruktioner - analyser och jämförelser
To build high-rise buildings made of timber has for long been limited by national laws, due to the lack of knowledge in engineering solutions. Frame structures made of wood has for a long time been associated with major fire hazards and consequently lower safety and this connection is still being made today. The increased environmental awareness in recent years has contributed to the exploitation of indigenous building materials, including wood from our own Swedish forests and has become increasingly common. Increased knowledge about how structures behave in fire and how they can be protected in order to achieve safe timber structures has resulted in a growing interest in these structures in the construction industry. Research in the area is constantly updated and new laws allow any number of storeys in wooden buildings in Sweden as long as the performance requirements are fulfilled.The main part of this work has involved calculations of the fire resistance and load bearing capacity of floor and wall constructions.
Småskaligt vattenkraftverk i Nyköpingsån
Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.
Närvärme med bioenergi i Västra Ämtervik :
I want to look at the possibilities to start selling hot water from a small district heating plant with bioenergy. My reason for doing this project is to look at a new business opportunity for our farm. Our company have less work during the winter time compared to the spring and this project will give us more work during the winter. I also want to take as much material as possible for heating from our farm in order to increase the value of the products from the farm.
The project is in a village near us, where we should support a school, a churh, a home
for the aged, a kindergarten and a parish hall with heat. In my work I have compared
two different alternatives with each other.
The first alternative is to put a central heater in one of the buildings, the home for the aged, in which we will burn oat.
Skolkod och pedagogisk förändring
Meeting the pupils at work it is important to endeavor an adjustment of the education with the purpose of developing the individual person. To make this possible it requires, except for the intentions of teaching with an individual adjustment, the teacher to make oneself acquainted with the schools work and liability. This is especially important in the work with students with difficulties. for this group of students perhaps an alternative form of education would be to prefer.As method of investigation I used a qualitative case study with a teacher who uses, what I would call, an alternative way of teaching. as a teacher you should pay attention to, and be aware of, how you effect your pupils and with this as a starting point conduct oneself.
CAP KC3-12 : Design and finite element analysis
In offshore oil production FMC Subsea systems use a product called cap. The cap´s mainly task is to protect hubface and seal areas on inboard hub against dirt, corrosion and mechanical damage under installation of a subsea system. A new model of a cap has been designed and analysed using finite element method. The model is called KC3-12 and has a new function, emergency release, which is a backup method for the ROV (remote operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2.
