Dynamisk massbalansmodellering av fosfor i Östersjön

During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.

Utredning av alternativa distributionssystem för Holmen Paper

Holmen Paper is one of Sweden?s leading manufacturer of paper, with two Swedish production facilities located in Norrköping and Hallstavik. The European continent constitutes the company?s largest customer base which makes the company?s distribution system an integral part of the business. Historically, much of the produced paper has been transported by vessels, as vessels allow large volumes of goods and deliveries to markets which are difficult to reach with other modes of transportation.

Självförvållad sinnesförvirring : Konsekvenser av att fingera tillräknelighet istället för uppsåt vid gärningar som begåtts under självförvållad sinnesförvirring

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.

En Djupdykning i Kommunikationsstrategi : om konsten att locka folk till svenska dykvatten

Purpose/Aim: To create a communication strategy for PADI Nordic with the intention of getting Swedish divers, who have been certified abroad, to Swedish dive centers.Material/Method: The study is based on a number of personal interviews conducted with a) divers who are active in Sweden, b) divers who are not active in Sweden and c) representatives from PADI and PADI affiliated dive centers.Main results: The main reason that people who have been certified abroad do not dive in Sweden is that they regard it as being too complicated, too cold, too expensive and with nothing interesting to see. These might partly be misconceptions that can be corrected through a communication strategic effort. The best way to change this perception is by two different forms of communication. One will go from PADI Nordic straight to the divers through an email. This will have the purpose of getting their attention, making diving sound interesting and raise their awareness in preparation for the other part of the process.

Miljöcertifierade byggnader Värde för investeraren

This bachelor thesis describes why investors should invest in environmentally certified buildings instead of non certified buildings. The report provides an overview of possible factors influencing an investor in the investment process of an environmentally certified building. The report explains why building companies find incentive to build green buildings and how a cash flow method can be adapted so it can be used in the valuation process of an environmentally certified building. Environmentally certified buildings are used as a strategy to reduce emissions that threaten the environment as well as a strategy to obtain market shares for the building companies. This report focuses on the economic advantages of an environmentally certified building.The construction- and real estate industry stands for approximately 40 percent of the energy consumption in the world.

Kommunikation, uppföljning och tidsplanering inom detaljprojekteringen : Hur projekteringsprocessen kan effektiviseras med små medel

Producing a building is a long and complex process. It consists of several parts, from the feasibility study and design stage onto the construction and finally the management of the building. The design process is a critical part of the process where construction plans are made. The quality of the plans affect the production phase in great extent and faulty plans can pose a risk for extra costs for all parts in the process. The cost of producing dwellings has increased the last years and the detail design process is one of many phases where improvements can mean cost savings within the whole building process.This report aims to point at parts within the detail design process which could be more efficient, regarding communication, follow-up and time planning, and to give suggestions for improvements.

Reala optioner : ett strategiskt verktyg

Background: Businesses are traditionally valued with the so called Discounted Cash Flow-model. When valuing newly-started businesses, surrounded by high uncertainty, and whose capital mostly consists of unrealized business opportunities, the Discounted Cash Flow-model needs to be complemented if the total value of the business is to be captured. A valuation with the help of real options is capable of valuing these unrealized opportunities, which often exist in newly-started businesses. The unrealized opportunities are to be found in the business plan of the business, why this needs to be valued to capture the total value of a newly-started business. Purpose: To demonstrate what the use of real options can result in when valuing businesses.

Utveckling av hygienfunktioner i diskmaskiner : Desinfektion med ånga

This report is the result of a thesis work in Integrated Product Development, regarding hygienic features in dishwashers and especially disinfection by the use of steam.The thesis is performed at Electrolux Primary Development Dishcare in Stockholm and in collaboration with the Department of Machine Design at the Royal Institute of Technology.The targets of the thesis are to prove the advantages of a technology suitable to implement as a hygienic feature inside a dishwasher and to realize a functional prototype of a differentiated hygienic feature that does not exist on the market today.The process followed to perform the thesis is the process defined for Electrolux Primary Development.The technology chosen for development is disinfection by heating the water on the surface of the dishware, by the use of steam.A number of tests on how steam behaves when injected into the dishwasher tub have been performed, providing the results that have been taken in consideration when designing the prototype.The prototype consists of a pipe system provided with nozzles to eject the steam into the upper parts of the dishwasher. Tests of the final prototype show that thermal disinfection of water in a dedicated area of the tub can be reached within 9 minutes. The operation requires 0,17 liters of water and consumes 0.2kWh..

Användarundervisning på webben design för lättillgänglighet och användbarhet

The aim of this thesis was twofold, on the one hand to compile a set of usability and accessibility guidelines in order to establish the characteristics of a user friendly website, and on the other to test these guidelines on eight library webcourses with user education to see how well they adhered to the guidelines. The methods used were literature survey and source studies. The guidelines found in the literature survey were divided into four different categories: document properties, structure and navigability, visual characteristics and accessibility. In order to establish the adequacy of the guidelines, I examined reference sources, mostly on the web. To a certain extent this examination has been based on HCI Human-Computer interaction theories.

Uppskattning av Ytkurvatur och CFD-simuleringar i Mänskliga Bukaortor

By applying a segmentation procedure to two different sets of computed tomography scans, two geometrical models of the abdominal aorta, containing one inlet and two outlets have been constructed. One of these depicts a healthy blood vessel while the other displays one afflicted with a Abdominal Aortic Aneurysm. After inputting these geometries into the computational dynamics software FLUENT, six simulations of laminar, stationary flow of a fluid that was assumed to be Newtonian were performed. The mass flow rate across the model outlet boundaries was varied for the different simulations to produce a basis for a parameter analysis study. The segmentation data was also used as input data to a surface description procedure which produced not only the surface itself, but also the first and second directional derivatives in every one of its defining spatial data points.

Försöksmetod för automatisering av kvalitetssäkring av SKB

Within all industries, there is a change in working time required; this also includes the construction sector. However, the way construction sectors are differentiated is by not having been given the opportunity to be practiced or tested.  The aim of this thesis that we have done in collaboration with the Concrete Industry was to investigate the possibility of developing an automated method for quality assurance of SKB at the site. The idea is to make the O-funnel to be more utilized and therefore ensuring that the appropriate concrete quality is provided which eventually would lead to a better development in the production process.The project has involved theoretical work and laboratory experiments. The theoretical work gave us a good foundation at the beginning of the project. After gathering the information and material, the laboratory experiments began by SCC in their laboratory in Hammarby. The collected data from the various laboratory tests formed the foundation for trying to relate measurements for consistency of SCC with each other and therefore find out how measurements from O-funnel varies with different concrete mixtures.
