Optimering av OTEC-system
Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.
Utlandsetableringar & aktieägares förmögenhetsvärde : En eventstudie om utlandsetableringars påverkan på aktiemarknaden
The aim of this study is to examine the market reaction when information about a company?s foreign direct investment is announced and how that affects the shareholder?s value. Also of interest is whether the market reacts differently depending on which country the investment is established in and which mode of entry is used. This will be achieved by using an event study approach. The selection that was used consisted of 206 companies registered on the Nasdaq OMX Nordic homepage, which had during a time period stretching from 1999 to 2009 established a foreign direct investment in the regions BRIC, Europe or the USA using the mode of organic growth, joint venture or acquisition.
????Att lösa reglertekniska problem med Modelica
Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.
Effektivitetsparadoxen - En eventstudie av handelsstopp på Stockholmsbörsen mellan 2003 och 2008
A trading halt is a measure conducted by a securities exchange in order to reduce information imbalances between market participants, thus enabling a higher level of market efficiency. A market is said to be efficient when new information concerning a company is instantly reflected in its stock price, implying that abnormal stock returns cannot be systematically achieved in an efficient market. The purpose of this study is to examine the occurrence of abnormal stock returns following trading halts on the Stockholm Stock Exchange. The study is based on a sample of 64 trading halts executed between January 2003 and February 2008. Historical daily prices for stocks subject to trading halts during the period have been gathered from the Datastream Advance database, while information on date and time of trading halts have been collected from the Stockholm Stock Exchange website.
Har börsen fått influensan? - En event-studie av huruvuda fågelinfluensan har påverkat finansiella marknader
SYFTE - Uppsatsens syfte är att undersöka huruvida uttalanden från Världshälsoorganisationen, gällande första händelsen av att vild¬fågel, hönsfågel eller människa blivit smittad av H5N1-viruset i ett land, har bidragit till abnormala prisrörelser hos aktuellt lands noterade företag med hönsfågelrelaterad verksamhet.METOD - Undersökningen är en event-studie där aktiekursers utveckling har undersökts vid informationshändelser rörande fågelinfluen¬san. För att estimera en jämförande normal avkastning har vi använt en kombinerad OLS- och ARMA-modellering.TEORETISKT PERSPEKTIV - Den effektiva marknadshypotesen är den grundläggande teorin som använts för att analysera insamlad empiri, som tillsammans med andra event-studier utgör det teoretiska ramverket.EMPIRI - 19 informationshändelsers påverkan på aktiekurser har analyse¬rats för att estimera normal och abnormal avkastning. Dessa 19 aktiekurser härstammar från 18 företag, belägna i sju länder.SLUTSATSER - Undersökningens resultat tyder på att undersökta företags aktie¬priser inte påverkats nämnvärt av Världshälsoorganisationens uttalande om att H5N1-viruset spritt sig till respektive företags land. Det finns dock ingen möjlighet att dra några statistiskt sig¬nifikanta slut¬satser grundade på undersökningen och dess analy¬serade empiri..
När tjejkvällen kom till byn. : En fallstudie av event marketing som ett intern- och externmarknadsföringsverktyg
En stor utmaning för ett säljföretag i dag är inte bara att identifiera och attrahera en specifik målgrupp. Det bör även skapa sig en bild av hur organisationen bör kommunicera med den presumtiva kunden för att skapa en stadig relation, som i sin tur kan borga för återköp. Situationen som uppstår då en försäljare för första gången interagerar med en kund kallas sanningens ögonblick. Det är vid detta ögonblick som grunden till en hållbar relation mellan säljare och kund förhoppningsvis läggs. Det är av högsta vikt för ett företag att försäljaren är införstådd i det beteende som företaget anser vara korrekt, och på så sätt återspeglar den attityd och kundbild som organisationen har för avsikt att förmedla gentemot kunden.
Cykeltidsoptimering av sjuaxligt robotsystem
This master thesis studies how much the cycle time, i.e. the time it takes for an industrial robot to perform a given task, can be reduced if an extra degree of freedom (DOF) is added to the robot system. The extra DOF consists of a linear track, which is supposed to be used in an optimal way. The problem has been studied using simulations in the robot simulation tool RobotStudio. To be able to run an optimization in Matlab, with the RobotStudio simulation cycle time as the object function, communication between Matlab and RobotStudio has been set up with an interface written in Visual Basic.
