Examensarbete · SLU

… made on behalf of SCA's Forestry Division and is a comparison of two bucking simulation tools: Aptan (manufactured by Skogforsk) and Best/upr (from Berget Systemdesign). The data is based on 32 stands from SCA's forests in Norrbotten and Västerbotten. The objective is to compare …

Bestämning av optimal fordonspark -Distribution av bitumen vid Nynäs AB

Examensarbete, grundnivå · Linköpings universitet

… hours for the truck drivers. Integer solutions are generated heuristically. Simulations that have been performed with the model reveals interesting differences concerning how the distribution is handled in different parts of Sweden. In western Sweden the transportation planning …

Cykeltidsoptimering av sjuaxligt robotsystem

Examensarbete, grundnivå · Linköpings universitet

… 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 …

Uppskattning av Ytkurvatur och CFD-simuleringar i Mänskliga Bukaortor

Examensarbete, grundnivå · Linköpings universitet

… 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 …

Modellering av manövercylindern för Nosstället på JAS39 Gripen

Magisteruppsats · Linköpings universitet

… for the Nose Landing Gear Retract Actuator on the JAS39 Gripen. During the simulations, upper and lower boundaries were calculated for the length of the spring and the diameter for the restrictor. The governing constraints were given by the requirements for the retraction time …

MEMS baserad referensoscillator

Examensarbete, grundnivå · Linköpings universitet

… an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured …

Transporttidsmodellering vid provpumpning i heterogen jord

spårämnesförsök i en isälvsavlagring

Examensarbete, avancerad nivå · Uppsala universitet

… a large number of stochastic conductivity fields were created and flow simulation was performed for each realization. From the simulation result, frequency distributions of the transport times were produced describing the probability for the transit time for a water particle …

Utvärdering och implementering av automatiska farthållare i fordonssimulator

Examensarbete, grundnivå · Linköpings universitet

… are becoming more common in vehicle industries. Company earns lot of money on simulations instead of real tests. Real tests are necessary but not made so extensively as before. In this thesis the building of an vehice simulator will be described and a comparison between three …

Direct-EGR tillämpat på HCCI

Masteruppsats · KTH

… are used, because of the possibility of increasing the injected fuel amount. Simulations in GT-Power were made to determine how the EGR-valve lift and exhaust valve lift should be made to transfer a certain amount of EGR with as good total efficiency as possible. The simulations …

UML som stöd vid småskalig utveckling av ett inbyggt system

Masteruppsats · KTH

… ArgoUML was used, but abandoned because of the greater potential for simulation in Rhapsody. Even though simulation did not take place, Rhapsody continued to be used, since it had shown to be easier to use from most perspectives. Foremost, UML has been a support to the …

Implementering av Patientsimulator för Anestesimaskiner

Examensarbete, avancerad nivå · KTH

… and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics …

Modeller för studier av ursprungsmärkt el

Examensarbete, avancerad nivå · KTH

… models; a single- and a multiarea model. The focus of the single-area model simulations was how to model consumers willingness to pay for electricity of a certain origin as well as the pricing. In the multi-area model impacts of transmission were included. The constructed …

Om hur en banks value at risk bäst skattas med expected shortfall

Kandidatuppsats · Lunds universitet

… upp VaR-talet vilket motverkar VaR-metodernas (speciellt likaviktad historisk simulations) riskunderskattning. En lagom ES-nivå vid volatilitetsviktad historisk simulation verkar vara cirka 97,3 %, medan en konfidensnivå runt 97,6 % tycks vara optimal vid likaviktad historisk …
