Today’s market for gas turbines is very competitive and it is important to constantly improve the performance of the engines. It is commonly known that gas turbines have better performance at low ambient temperatures than at high ambient temperatures. One way to counteract the negative influence of a high ambient temperature is to use variable compressor guide vanes. The aim of this thesis is to e
Sri Lanka is an island that suffers from high suicide rates and is ranked as one of the top countries in the world that have people committing suicide. Sri Lanka has been through Tsunami and a long time of conflict during a civil war. The aim of our study is to clarify how health workers talk about the high suicide rates in Sri Lanka. This is a qualitative study with an inductive approach which to
The purpose of this study is to examine how swedish social workers describe the three different element of care that are described in the swedish forced law concerning children and youths. I have used a discourse analysis to capture the descriptions and how they construct the elements. The study contains six investigations about teens who have a risky behaviour and requires care without their cons
In the light of the financial crisis of 2008, risk management has become one of the most important topics in the financial world. This study applies five different VaR approaches, normal distribution, student’s t distribution, historical simulation, age weighted historical simulation and volatility weighted historical simulation under three different sample windows. These parametric, non-parametri
Interaktionsmöjligheter i sociala medier har bidragit till att varumärkesinnehavare har fått minskad kontroll över vilka budskap som kommuniceras om varumärket. Studien analyserar hur värde i relation till ett varumärke förhandlas mellan använ-dare inom en gemenskap på Instagram, samt hur normer och gruppstrukturer på-verkar och påverkas av förhandlingsprocesser inom gemenskapen. Studien bygger påThe possibilities of interaction in social media has contributed to a reduction of control for brand owners when it comes to what is being communicated about their brands. This study analyses how value in relation to a brand is negotiated between users within a community on Instagram. The study also analyses how norms and group structure affects and is affected by the negotiation processes within
Slutsats visar att infrastruktur, samarbete och ansvar är ovillkorliga förutsättningar vid införande av en mer hållbar avfallshantering. Infrastruktur eftersom det kan vid rätt implementering underlätta sortering av avfallsfraktioner, som gör att avfallets värde lättare blir tillgängligt. Ansvar för att belysa hur enskilda handlingar kan främja eller hämma andras insatser för hållbar avfallshanter
The purpose of this study was to examine in which range social work in a informal security regime is professional in the case of Sri Lanka. We used a qualitative method, interviewing four socialworkers in a non-governmental organization in Sri Lanka. We also introduced a case in the end of the interviews for the socialworkers to respond to. The study shows that the socialworkers don´t have any for
En sammanställning av större geoenergianläggningar i Sverige har i samband med detta arbete gjorts. Arton anläggningar med bergvärme, borrhålslager, högtemperaturlager samt akfiverlager ingår i denna. Utifrån information om dessa anläggningars drift har rekommendationer för mätpunkter getts för att bättre säkra mätning och driftuppföljning. Geoenergi är Sveriges tredje största förnybara energikällShallow geothermal energy is the third biggest renewable source of energy in Sweden. Low-temperature energy stored in the ground and groundwater is collected by a ground heat exchanger with circulating brine and a ground source heat pump, GSHP. It is possible to extract both heating energy and cooling energy in these systems; in the winter the earth is utilised as a heat source, and in the summer
The Water hyacinth is one of the worst aquatic weeds in the world and it is today present on all continents except Antarctica. It causes big problems for both people and the aquatic ecosystems in many countries. A lot of research has been completed to find methods to eradicate the weed and a lot of money has been spent on management to keep waters clean. In this literature study on management meth
Energy Management needs global attention due to increase in energy demands over last two decades. Commercial buildings and Industrial Facilities are the two most intensive energy consuming sectors that results in high energy expenditure cost and carbon emissions. They have shown interest in energy efficiency and energy management programs to save energy and reduce carbon footprints due to governme
The ability for organizations to respond to change has become ever more important in today's rapidly changing macro environment. The Business Rules Approach, a relatively new Information Systems Development methodology, promises business agility through the focus on and use of Business Rules. Business Rules are to be stated in natural language, so that they can be accessed and validated by peo
Grey-box identification is a tool to identify and improve nonlinear system models by estimating parameters. The estimation is done by optimizing a cost function using measurement data. The robustness of the estimations can then be analyzed with statistics. JModelica.org is a platform for modeling and optimization of dynamical models. In order to do grey-box identification one need models and be ab
Different simulation tools often have their own definition of how a model is represented. This causes complications when modeling in one tool and trying to simulate in another, or if one wants to verify simulation results in another tool. This thesis focuses on a way of interfacing the Functional Mock-up Interface (FMI) into Modelica models. Modelica is an open standard modeling language for model
Informationsdelning behövs för att kunna skapa konkurrensfördelar och träffsäkra försäljningsprognoser på en marknad där marginalerna är små. Även om fördelarna är många av ett gemensamt utbyte av information så finns det flera omständigheter som hämmar företag från att ingå i samarbeten där känslig information lämnar organisationen. Syftet med studien är att undersöka hur informationsdelning sker
Idag söker människor värden utöver de som går att återfinna i fysiska produkter och det blir därmed en väsentlighet för företag att öppna upp för ett gemensamt värdeskapande med kunden. För att lyckas skapa värde blir det nödvändigt för företagen att förstå kundens behov, vilket i sin tur innebär att företag måste befinna sig där kunden är - idag befinner sig en stor andel på sociala medier. Den i
Emotions are influential in determining individuals to donate to charitable causes. However, emotions could interfere with the later decision to whom to allocate the donation resources by making people more likely to donate to a few individual victims instead of many statistical ones. Nevertheless, rationality could direct the allocation decision on the right way (i.e., by donating to statistical
Samhällets utveckling har bidragit till ett förändrat medielandskap vilket medfört ett engagemang som antagit nya former. Detta har skapat nya möjligheter för individer att uttrycka sitt samhällsengagemang, möjligheter som dock har börjat ifrågasättas. De senaste årens forskning inom engagemang på sociala medier visar en tvetydig bild av engagemanget där åsikterna går isär. Syftet med denna studieA click for a better world The media landscape has changed along with developments in society. This has resulted in new forms of engagement which has created new opportunities for individuals to express their civic engagement. However, these opportunities are now starting to be questioned. The last years research in social media engagement show an inconsistent picture of the engagement with compe
Bakgrund: Mellan 1994-2004 skedde en dubblering av antalet nya fall av prostatacancer. Idag görs en majoritet av prostatektomierna laparoskopiskt med robotassistans. På Urologiska kliniken SUS, Malmö siktas vårdtiden efter en okomplicerad prostatektomi, vara ca 1,25 dagar. För att uppnå detta mål krävs en jämn nivå med hög kvalitet på vården. Syfte: Beskriva det intra- och postoperativa förloppe
