Simulering av vindkraftverk och närliggande elnät vid Risholmen i Göteborg i SimPowerSystems
With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.
Litterära Cirkeln : En studie hur Cirkeln av Mats Strandberg och Sara Bergmark Elfgren diskuterats på bokbloggar i anknytning till nätbokhandlar
The purpose of this bachelor thesis is to examine posts on bookblogs about the book, Cirkeln by Mats Strandberg and Sara Bergmark Elfgren and see how it has distributed amongst readers through social media and reader response. We want through this examine whether bookblogs have a place in the literary society, and in such cases, how this may take place. The Swedish Online bookshops Adlibris and Bokus is being used to find the blogposts to be examined in this thesis. The analysis is being implemented using content analysis and constructed encoding schemes. Interdisciplinary topics, like LIS and sociology of literature may have similar points of contact, which we want to highlight with this thesis.
Erfarenhetsöverföring inom markarenan med stöd av simulatorteknik. : En studie av StriSimPC.
One of the main tasks of the Swedish Armed Forces over the past few years has been International assignments, which increased the importance of the Lessons Learned process. Methods of simulator training with computers have become more frequent and the technical ability to collect digital data from sensors has been developed as well. This work demonstrates how the experience of Lessons Learned can be communicated with the computer simulator StriSimPC and how modern technology in future support experiences from the Lessons Learned process at the tactical level in the Army.Currently knowledge sharing consists of several processes and strategies in the Swedish Armed Forces. This is done by written reports, oral presentations and different practical exercises.This case study shows the functions of the simulator StriSimPC, methods of training and how it is used today. The study also describes the future opportunities, where digital metadata acquired from the modern combat vehicles could contribute sharing of experience in the Lessons Learned process.The summarized conclusions indicate that StriSimPC can combine the two strategies for personalization and codification of knowledge transfer to reach a higher level of learning.

Effektiv signalering av kritisk information : sepsisvarning på en akutvårdsavdelning
Denna studie har som syfte att undersöka hur signaler på en akutvårdsavdelning påverkar akutvårdspersonalen idag samt hur en varningssignal för sepsis bör utformas för att passa in i miljön och minska risken för larmtrötthet. I studien har kvalitativa metoder använts i form av observationer på en akutvårdsavdelning samt tre stycken intervjuer. Datamaterialet har sedan analyserats med hjälp av det teoretiska ramverket Distributed Cognition for Teamwork (DiCot). Studien resulterade i en kartläggning över vilka signaler som finns på akutvårdsavdelningen idag, där sepsis skulle klassas som en akut varningssignal och ha högsta prioritet i förhållande till de andra signalerna. Varningssignalen bör i de fall då patienten ligger på ett övervak presenteras så att den når all personal och med säkerhet uppmärksammas. I de fall då vårdlaget befinner sig på platsen när varningen kan uppstå bör larmet istället vara mobilt och enbart presenteras för vårdlaget.
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.
Ur chefens synvinkel : - om ett jämställdhetsprojekt i Kalmar kommun
Kalmar Municipality has in 2008-2010 made an effort to educate managers on gender, with the goal of mainstreaming gender into public activities so that all citizens should feel safe in that treatment and services are designed and resources are distributed equally to both sexes living conditions and needs. The overall aim of this study was to examine whether the training effort has paid off, and how gender mainstreaming has been implemented in the different activities. We have used a qualitative approach, which we examined through interviews managers' approach to gender equality.Gender was generally described as an important issue of all respondents, and all were working to mainstream gender into their activities and workplaces. The results show that the operational and management needed clearer directives and strategies in their efforts to promote gender equality. Education was necessary because personal definition of gender may differ from the control contents of the documents.
Industriellt Byggande? En Studie av ICT-Verktyg förInnovativ Produktframtagning
EPiServer is a content management system where users can publish information on a website by using a web browser. EPiServer has a built-in search engine that is very simple. Many customers using EPiServer web publishing system is in need of more functionality than is offered by EPiServer's built-in search engine. The purpose of this thesis is to develop additional functionality extends that the built-in search engine in EPiServer. The assignment was also to identify what need to be developed in order to give customers a better opportunity to help their visitors find the right information on their website.Since this thesis was started in 2005, a number of commercial search engine productsentered the market and it has become more common for companies to invest inthese products instead of using the simple search engine that's built into EPiServer.These products have many of the features that have been developed in this thesis.Another crucial difference between EPiServer?s built in engine and other products isthe method used to index content.
Torrefaction of biomass : a comparative and kinetic study of thermal decomposition for Norway spruce stump, poplar and fuel tree chips
Stump biomass is energy rich and stump harvesting for use as fuel become more and more
interesting in Sweden. Swedish Forest Agency (2009) has estimated that stump harvesting in
Sweden would respond to an annual energy supply of 57 TWh/year. However, stump has not
been recognized as a bioenergy resource in Sweden. Suitable methods for pre-treatment of
stump are probably of great importance to make it accepted as fuel. It is therefore rewarding
to carry out an investigation in this area for stump.
This report represents results from a diploma project, which was aimed to develop a fixed bed
reactor for experimental study of biomass torrefaction, followed by TG analysis and kinetic
modelling employing Ozawa method and different kinetic models including one-step and
three-pseudo-component models.
Förekomst av sex- och samlevnadsundervisning på gymnasienivå - ungdomars kunskaper och attityder angående sexuellt överförbara sjukdomar och kondomanvändning ? en tvärsnittsstudie
Sexually transmitted diseases among youths is a growing problem. Generally, the knowledge about sexually transmitted diseases is relatively good, however, the risktaking among youths is great. The schools education regarding sex is often insufficient. The foundation for avoiding STD is knowledge. However, knowledge does not solve the attitude problem regarding the use of condoms.
Ett säljsamtal via webbutik : Visma SPCS
The main objective of this thesis is to study how the structures of a sell dialog, via a web shop, should be designed in order to support and inspire the customer. To get the answer to this question I use a qualitative and quantitative method. The qualitative method is applied in connection with different interviews. The quantitative method is used to analyze different answers given from those who are interviewed. I also use the deductive method due to my interest of studying how reality can relate to the theories with the choice of the subject.Moreover, this thesis is structured by three main perspectives; company, customers and techniques.
Erfarenhetsåterföring i Sveriges två ledande byggbolag : Riktlinjer, utfall och konsekvenser
The construction industry in Sweden has in the past 50 years had a low progress in efficiency. With a greater competition from construction firms from other countries, it is necessary to maintain the profit for Swedish construction firms. This is possible with a higher feedback of experience. This diploma work thesis examines how the two construction companies NCC and Skanska in Uppsala, Sweden handle experience feedback from previous projects and the extent to which the experience is spread and used in future projects. In this work, we examined directorial documents to see how employees shall work with feedback.
Design av försöksanläggning för trycksatt rökgasrening vid oxy-fuelförbränning
Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

Bygelstolpar : Kraft- och spänningsanalys av bygelstolpar tillhörande Bruks mobila hugg 805 CT
This report is the result of a thesis as been implemented during the spring term 2009 atthe University of Gävle.The company Bruks produces mobile chippers which are used for chipping loggingslash, roundwood and parts of trees. The chipper is powered by a separate diesel engineand the chipper can be assembled on trucks, trailers or some other carrier vehicles.When the chip has passed the chipper drum, the chip is collected in an integrated binwhich is mounted on the vehicles frame with dumping yokes. When these dumpingyokes were designed they were probably created with large material dimensions. Theaim with the degree project is hence to study the strengths of materials and, if possible,to suggest an arrangement that can decrease the total weight on the dumping yoke onBruks´ mobile chippers 805 CT.The CAD-program Pro/ENGINEER was used during the project for outlining the 2Ddrawings,as distributed of constructors on Bruks, to solid 3D-parts. The three-dimensionalassembly from Pro/ENGINEER was transferred to Pro/MECHANICA.
