En teleologisk undersökning av införande av enkvalitetsstandard

The study examined what NHL-teams should improve. This has been done by studying the significant statistics of NHL-seasons, and with linear regression identifying what NHL-teams should do to win many points and thereby get a good placement in the final table. The most interesting result of the study is that the statistics on faceoffs and shots on goal and power play efficiency most seasons where irrelevant for the outcome of a season..

Jämförelse av verklig och modellerad elproduktion från en solcellsanläggning : En utvärdering av två simuleringsverktyg.

This thesis has been carried out in New Zealand in collaboration with the University of Waikato. In association with Dr. Mike Duke the purpose of this work is to investigate whether two different software for modeling of photovoltaic systems are useful in the teaching of solar energy.The next ten years grid-connected photovoltaic systems are assumed to increase and therefore also a rising demand for people with engineering knowledge are to be predicted. For engineer students with a focus on solar energy a more practical teaching with design software´s can be a good method to make the students comprehend more when it comes to large scale photovoltaic systems and be more prepared for working life.The software´s used is called Transient System Simulation (TRNSYS) and Photovoltaic Systems (PVSYST) which are both well used throughout the world. To assess the reliability of the software´s, a reference solar power plant at 16.1 kWp installed capacity are used, which consists of photovoltaic modules from four different manufacturers.

Gruppering av sinkor i stora besättningar

The dry period is usually 6-8 weeks and in this period the basis of the performance in the following lactation is settled. In an average herd about 15% of the cows are dry (Marcussen & Krog Laursen, 2008). In many herd the dry cows are set aside, that means setting aside 15% of your herd, at the time when they are preparing for their next lactation. The recommendation for number of groups differs depending on country traditions or reasons for grouping. If you look at recommendation for feeding, some companies selling feeding equipment advocates one group throughout the dry period, but the number differs from one to three.

Den personliga kreativiteten: Kreativitet är vad du uppfattar och beror på dina egna erfarenheter

Previous research within the field of advertising creativity has been based on the point of view of professional advertisers, deciding the norms of creativity without wondering how consumers define creativity. Thus, the main purpose of our thesis has been to investigate which dimensions advertising creativity consists of and the driving forces behind them. All based on a consumers? point of view. The secondary purpose has been to show how creativity affects efficiency through purchase intentions and Word- of-Mouth.

Forestry supply chains : preparing for the unpredictable

Forestry supply chains are a significant part of the Swedish economy. These supply chains are highly susceptible to storms damage. In late 2013 Sweden was hit by multiple storms. This leads to the possibility to research how supply chains react to the shocks that storms cause. The aim of this thesis is to research the costs that storms increase, the actions that are taken within the forestry supply chain, as well as possible benefactors from storms. This thesis bases on previous work on supply chain mapping and cost theories.

Miljöklassningssystem : Skillnader mellan Miljöklassad Byggnad och LEED samt dess påverkan på fastighetsvärdet

A uniform environmental rating system for green buildings is demanded in today's society, where the requirements of the energy consumption for real estate are increasing. There are several different systems around the world used to rate buildings, all with different assessment criteria and starting points, which make it difficult to compare environmental rated buildings with each other.The purpose of this paper is to acquire knowledge about the differences between the Swedish environmental rating system Miljöklassad Byggnad and the American LEED, to discover which system is most advantageous. We also examine whether environmental rating affect the value of a property.Miljöklassad Byggnad is relatively simple structured, which makes it possible for private individuals to rate their property. LEED is better structured on the other hand in the case of environmental classification of commercial properties, because there are manuals for among others hospitals, schools and retail. The rating system for Miljöklassad Byggnad is good since the system seeks to fix the number of errors and deficiencies as soon as possible.

Anaerob rening vid StoraEnso Skoghalls Bruk

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

Chalmers oanvända datorkraft - Distribuering av arbete och energihantering med HTCondor

Chalmers University of Technology today have numerous computers which are never powereddown, at the same time there is a need for more computation power for researchers.Hence, we have investigated the possibility to use the computers for computing power andsecondly, if there is no work to be done, to put them into power saving mode.We have made a thorough study where we compared different distributing systems andin the end HTCondor was chosen as the best to implement. HTCondor is an excellent systemfor opportunistic use of computing power, i.e. make use of computers that no one elseis currently using. The system is used at several universities around the world with goodresults and would be excellent at Chalmers, where there is a need for such a system.Our implementation shows that HTCondor is well capable of handling unused computingpower. HTCondor can handle most file types that may be run on the system.

Mål- och resultatstyrning inom domstolsväsendet: En fallstudie inom Migrationsdomstolen i Stockholm

The aim of this study is to enhance the knowledge of target and performance management?s effects on the judiciary. In the past decades there have been a number of reforms in the general public sector of many countries. The management philosophy often used to describe these public sector reforms is called New Public Management (NPM). One main theme has been an increased focus on the management control systems, for example a greater emphasis on target and performance management.

Klimatinducerade fenologiförändringar och dess effekter i näringsväven

The climate affects animal populations through several processes. These processes includereproduction, phenology and the success of hunting. By influencing the phenology of species theclimate also affects the way species interact. If a climate-induced phenology change promotes abasal species to bud earlier in the spring for example, this will affect the links to other species inthe food web due to a time lag in the tropic levels above. This dependence, that a predator has tobeing synchronous to its prey, is called the match/mismatch hypothesis (MMH).

Samband mellan lågt tryck i dricksvattenledningar och magbesvär - En utredning av hur lågt tryck på dricksvattenledningsnätet vid lagning av läckor påverkar sjukligheten hos Göteborg Vattens abonnenter.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
