Jämförelse av olika metoder att generera Bernoullifördelade slumptal givet deras summa
In this master?s thesis the problem of simulating conditional Bernoulli distributed stochastic variables, given the sum, is considered. Three simulation methods are considered, namely the acceptance/rejection technique, Bondesson?s method and the Markov chain Monte Carlo method.To compare the three methods the bias and the standard deviations of the simulated variables are evaluated. The results of the simulation study shows that the Markov chain Monte Carlo method is not the best method for this type of simulation.
Laborationer med trådlösa sensornät
Trådlösa sensornät (eng. Wireless Sensor Networks, WSN) är ett snabbt växande teknikområde med många applikationer. Ett typiskt WSN består av en mängd små billiga och energisnåla enheter, så kallade sensornoder, som mäter någon miljöparameter och via radio skickar ett datapaket med uppmätt värde till en basstation som ofta är kopplad till en PC. Informationen kan därefter analyseras eller redovisas grafiskt för användaren. Sensornätverkets storlek kan variera från några få noder på en liten yta till nätverk med tusentals noder som täcker flera kvadratkilometer stora områden.
Finns det genvägar för bearbetning av hotstimuli
För att undersöka resursallokering av processresurser vid informations-bearbetning av hotstimuli har ett ?Dual Task? experiment utförts med spindelrädda försöksdeltagare. Uppgiften bestod av att respondera på olika probe-stimuli som exponerades, direkt på bilder av olika djur (däribland spindlar), med olika tidsintervall. Latens och träffsäkerhet mättes, för ett mått på prestation, och EKG användes för att kontrollera att spindel-bilderna faktiskt utlöste rädsloresponser. Resultaten visar att större processresurser allokerades till spindelbilderna jämfört med alla de övriga bildkategorierna, men att denna differentiering inte verkar ske innan en kognitivt kontrollerad bearbetning och utvärdering av stimulus ägt rum.

This report is part of a Bachelor?s degree corresponding to 15 creditsat the Royal Institute of Technology, Stockholm. The work hasbeen carried out by Max Wikander, author of the report, supervisedby Lanie Gutierrez-Farewik and Erik Dijkstra.Gait analysis includes measurement, characterization and assessmentof human movement and is used to assess kinematic or otherabnormalities during gait. Center of rotation and the axis of rotationof a joint are fundamental parameters in motion analysis. However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.

Besparingsmodell för produktivitetshöjande arbete inom skärande bearbetningsteknik
The market is developing and a growing competition increases pressure on companies to maintain their competitive advantage. Working with cost savings is a way to enhance earnings in a short term but also in a longer perspective. Volvo Powertrain Production Köping has an overall goal; to reduce costs by nine percentages in three years. To achieve the goal, Volvo Powertrain Production Köping works with World Class Manufacturing where the Department of Processing Technology constitutes an important part.Volvo Powertrain Production Köping lacks a standard for how savings within the metal cutting tool area are to be calculated. This makes it difficult to control and monitor their business outcome but it also causes difficulties in controlling the tool suppliers? outcome.
Havanna Viejas Trädgårdar : En lösning på urban matsäkerhet
High oil prices and bad harvests have led to dramatic increases in food prices and are nowthreatening millions of people in densely populated cities all over the world. To ensure thatthese people will have enough food without compromising the needs of future generationswill be a demanding task for politicians and decision makers. ?is paper has shown thatHavanas urban gardens have increased urban food security since the hunger crisis thatoccurred a?er the fall of the Sovjet Union in 1989, and that they support the thesis of Amartya Sen and the Ryerson University. Urban gardens can be a good example for cities how to avoid hunger and famine if they are properly managed.

Textens inverkan på matematiska uppgifter : En undersökning om elevers textförståelse av matematikuppgifter i årskurs 5
The purpose of this study is to show the importance of task texts for students in grades 5 when solving mathematical problems. It was conducted in a class 5 (where the children are 11 years old). The pupils were assigned two different tests with mathematical problems; one where the problems were described in text and one where the problems were presented with numbers and mathematical signs. Previously done research, done on bilingual children, (Bernardo, 2002) shows that pupils tend to do better on mathematical tests when no text is presented. My research supports that theory even though the correlation is not that strong.
Kliniskt handledarskap med hjälp av Informations- och kommunikationsteknik (IKT) : - En intervjustudie
The purpose of this study was to describe senior nurses? expectations concerning how a digital information and communication technology systems (ICT) can contribute to the improvement of care leadership and how it can strengthen ties between the school's theoretical world and the practical clinical work-based training (WP) in nursing. The study has a descriptive design with a qualitative approach. The study involved seven leading care nurses. Data were collected through semi-structured interviews.
Hästar i skrämmande situationer : en jämförelse mellan hanterad respektive fri habituering
In connection with riding and handling of horses, many accidents that can cause severe injuries to both horses and humans are existent. The cause is in most cases that the horse is frightened. The horse's fear also affects its usefulness and it has been shown to have adverse effects on the horse's welfare. To increase safety and improve the welfare of both humans and horses, it is important to find appropriate training methods to reduce the fear of horses in frightening situations. This experimental study compares handled habituation to free habituation.

Analys och förbättring av en mätenhet för laddning av elfordon
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.
