Transporttidsmodellering vid provpumpning i heterogen jord : spårämnesförsök i en isälvsavlagring
When protection zones for wells are delineated, it is important to acquire good knowledge about possible travel time from different points in the catchment area to the well. Often, simple analytical methods are used for estimating travel times and the assumption is made that the hydraulic conductivity is relatively homogenous within the aquifer. Nevertheless, many aquifers are strongly heterogeneous which may lead to differences between estimates and actual travel times. As a part of the process to develop improved methods for delineating protection zones for groundwater supply wells, a tracer experiment was performed in a glaciofluvial esker formation in Järlåsa. On the basis of the experiment, a numerical flow model was created for the test site.The purpose of this master?s thesis was to apply the flow model to an aquifer where the hydraulic conductivity shows great variability and should be described by a stochastic distribution.
Företrädaransvar enligt SFL
This thesis, in the field of healthcare logistics, has been carried out at Hjärt- och Medicincentrum (HMC) at the University Hospital in Linköping during the fall and spring of 2012/2013. The thesis is done by two students at Linköping University at master?s level within the framework of Industrial Engineering and Management.As Sweden's county councils should not make a profit or loss, it is important that the councils are aware of how much care processes cost. Kardiologiska kliniken at HMC in Östergötland?s county council is one of the clinics that are profitable.
Kommunikations- besluts- och informationsflöden i byggprocessen
Construction projects are organized in different shapes and disturbances in the information flow in these processes can lead to problems, such as delays and/or a lower quality. Therefore, a well-functioning interaction between actors and a well thought out-communication at an early stage is of crucial importance. The main question is "How does the communication of decision and information flow in the building process and what barriers and opportunities can be observed?". This diploma work has been written with guidance from Bjerking AB and to answer this question, a collection of empirical data conducted via semi-structured interviews.
Sälj innan köp! : En studie om hur spelarövergångar påverkar fotbollsklubbars aktiekurs
Pengarna rullar allt snabbare inom fotbollen och från Southampton säljs de båda tonåringarna Theo Walcott och Gareth Bale för £5 miljoner styck. Båda de händelserna följdes av ett kursfall för Southamptons aktie vilket skulle kunna tolkas som att marknaden inte tyckte det var goda nyheter. Detta leder oss till vår problemformulering:Hur påverkas börsnoterade fotbollsklubbars aktiekurser vid spelarövergångar?Syftet med uppsatsen är att undersöka om det finns en avvikande avkastning i samband med en spelarövergång. Vi undersöker även om det är någon skillnad mellan spelarköp och spelarförsäljningar.
Det norska energideklarationssystemets konsekvenser för äldre byggnaders karaktärsbärande värden
Roughly 130 000 dwellings have been officially registered since Norway as of summer 2009 passed their bill ?Energimerkeforskriften? on energy performance certificates in buildings. The main objective is to decrease the total amount of national energy consumption by producing a methodology of calculation of the integrated energy performance of buildings as well as proposing cost effective measures to lower each building?s energy consumption. As the measures should not contravene nor be incompatible with the intended quality and character of the building, the ?Energimerkeforskriften? exempts buildings that due to their historical and cultural values are protected cultural heritage legislation. The current system offers a couple of professional certification alternatives, but when two online semi-automatic methods developed specifically for non-professionals are by far the most used, and since the methods of calculation primarily have focused on modern building materials and construction, the rest of the historical building stock stands literally unprotected by incorrect performance certificates and high-risk energy efficient measures. The objective of this thesis is to identify if the current Norwegian energy certificate system poses a threat to older buildings.

Analysverktyget Stockluckan ? fast eller rörlig postning?
I dagens moderna barrsågverk finns två tillvägagångssätt för att mäta in och tudela stockar. Antingen ställs maskinerna om inför varje stock för att sågmönstret ska passa denna på bästa sätt och på så sätt få ut ett så högt värde som möjligt ur varje stock. Denna metod kallas ?rörlig postning?. Den andra metoden går ut på att dela upp stockarna i timmerklasser så att stockar av liknande dimensioner hamnar tillsammans och sågas efter varandra.
Aktiesammanställare med teknisk analys och simulation
Websites today only offer simpler form of technical analysis and are not fun to use, therefore student decided to build a website that makes technical analysis a bit more fun by giving user possibility to experiment with settings for technical indicators and also see clear visible results from analysis. Student decided to build website in ASP.NET. Technical indicators for this project only consist of those who give buy and sell-signals via cross-over, no divergence or pattern finding.This project has three questions that define this project. It?s important that there is good functionality so that performing an analysis is perceived as simple, one question is therefore; what functionality for website is needed in order for analysis to be perceived as more simple?Technical analysis is a pretty complex subject and demands an interface that is perceived as easy to understand and easy to use, it?s therefore important that the interface is well designed, second question is therefore; how should the interface be designed to be user-friendly?When systems grow large they often become hard to develop and later on unmaintainable because of the accumulated complexity and dependency between classes, the code is a mess, the last question is therefore; how can the systems complexity be eased with object-oriented design principles?Jakob Nielsens ten heuristics for User Interface Design were used as inspiration for designing the interface for the website.
Vilken kommunikation smörjer börsmaskineriet: En kvalitativ studie av börsanalytikers syn på informationsinsamling och trovärdighet
Stock analysts have through the analyses they write a large impact on the expectations on the market and the direction of investors investments. This creates undesired fluctuations on the market that raises the level of uncertainty. The way that the analysts satisfy their need for information is connected to how their final analysis will be shaped. There is a large knowledge gap concerning the way that the analysts work and this gives unsatisfactory ways of communication. This thesis is set out to create a greater understanding of how optimal communication towards this target group should be brought out.
Kina- och Rysslandsfonder : En jämförande studie i nedgång och uppgång av den svenska börsen
Purpose: Aims of this paper is to evaluate a comparative study between China and Russia funds in respect of the risks and returns. We also want to examine what has affected the funds in their respective domestic stock market. Method: The study is based on qualitative methodology to complement the quantitative survey by first gathering of secondary data from Morningstar, and fund manager´s stories on fund and banking companies' websites. Primary data is conducted by the interview with fund manager. The sample consists of all land funds for China and Russia has found more than 10 years on the stock market.Results and Conclusion: The survey shows that China funds will generate better in decline than Russia Funds in both return and risk-adjusted Sharpe ratio. Because the China funds had better risk diversification and its holdings spread across different industry area while Russia funds is more directed towards oil and gas industry.

Tidiga membranförändringar i hingstsperma som används för artificiell insemination :
The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.
