Fluid Simulation for Visual Effects

Examensarbete, grundnivå · Linköpings universitet

This thesis describes a system for dealing with free surface fluid simulations, and the components needed in order to construct such a system. It builds upon recent research, but in a computer graphics context the amount of available literature is limited and difficult to …

Utvärdering av laddningskoncept för lastbilsbatterier

Examensarbete, avancerad nivå · KTH

… Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made. Some tests are made in a real truck but the evaluation of the charging methods is mainly based on battery tests made in the laboratory. The methods and procedures for …

Differentieringsgradens inverkan på Kriminalvårdens platsbehov

en simuleringsstudie

Examensarbete, grundnivå · Linköpings universitet

Kriminalvårdsverket är det statliga verk som har hand om kriminalvård i Sverige. Vid årsskiftet 2003/2004 finns det 4 571 nominella anstaltsplatser fördelade på män och kvinnor. Ett stort problem idag är att antalet anstaltsplatser inte räcker till, samtidigt som ekonomin inte …

Feldiagnos för RM12 baserad på identifierade modeller

Examensarbete, grundnivå · Linköpings universitet

… engine with these faults present was made. Based on this analysis an existing simulation model of RM12 was modified, so that these faults could be simulated. For the purpose of fault diagnosis two models were developed for two different engine parameters, one linear state space …

Modellering av indunstning på Södra Cell Mönsterås

Examensarbete, grundnivå · Linköpings universitet

… of the evaporation at Södra Cell Mönsterås and has been constructed using the simulation program Extend. The Extend model is a block based, static model, which describes energy and mass flows of liquor, steam and condensate. The other model consists of a dynamic, parametric …

Matematisk generering och realtidsrendering av vegetation i Gizmo3D

Examensarbete, grundnivå · Linköpings universitet

… This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to …

Studie av integration mellan rategyron och magnetkompass

Examensarbete, grundnivå · Linköpings universitet

… attitude’s accuracy. To investigate and evaluate the navigation system, a simulation model has been developed in Simulink/Matlab. The implementation has been made using a Kalman filter where the sensor fusion takes place. Simulations for different scenarios have been made and …

GALS,Design och simulering för FPGA med VHDL

Examensarbete, grundnivå · Linköpings universitet

Heat, clock scew and frequency optimization are some of the problems a semiconductor designer must face. By splitting a synchrounous block into multiple pieces which comunicates asynchronously with eachother and provide them with independent clocks, these problems may be …

Analog-to-Digital Converter Design for Non-Uniform Quantization

Examensarbete, grundnivå · Linköpings universitet

… techniques to compensate for a multi-bit DAC nonlinearity. High-Level Simulations of the second-order Sigma-Delta modulator single-bit feedback topology along with a Semi-Uniform quantizer are performed in Cadence. Results indicate that a 5-bit Semi-Uniform quantizer with a …

Konstruktion av current conveyors via makromodellering

Examensarbete, grundnivå · Linköpings universitet

… validate that it was sufficiently accurate in comparison to transistor level simulations. This was realized through calculation of behavioural specifications and then transferred to the linear macro model. A method for calculation of component values in the linear macro model on …

Design och tillverkning av en stereoanläggning med aktivt delningsfilter

Examensarbete, grundnivå · Linköpings universitet

… control. The section about design accounts for the layout of the system and simulation results show how the system should work. The section regarding construction presents the practical stages of the project. Finally, measurements that were made are presented. The constructed …

Massbalansmodellering av fosfor i ett åländskt kustområde

en utredning om lokaliseringen av Lotsbroverkets utloppsledning

Examensarbete, avancerad nivå · Uppsala universitet

… to, from and within the defined areas were studied and ranked. Model simulations have shown how changes in any of the phosphorous fluxes influence the mean monthly concentrations of total phosphorous. The situation for total nitrogen was determined with a statistical/empirical …

Simulering av COD-fraktioner i en aktivslamanläggning vid en sulfatmassafabrik

Examensarbete, avancerad nivå · Uppsala universitet

… in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant …
