Simulering av kabelbränder i sekundära säkerhetssystem med CFD-koden SMAFS

Kandidatuppsats · Lunds universitet

This report contains CFD-simulations of cable tray fires in nuclear power plant applications with the CFD-code SMAFS. Furthermore the report evaluates the use of CFD-codes within this kind of problems. The assessment of this report is that there is a tendency towards the good …

Skötsel av älgskadade bestånd :

Examensarbete · SLU

… had serious damage, in average 46.9 % of the pine had viewable damage. A simulation of eight different management alternatives was done for each stand. These were conducted with ProdMod2, which is a computer program that can calculate the production on a stand. For the economic …

Användning av satellitdata för lokalisering av skogsområden där lövröjning bedöms angelägen

en analys av användbarheten med fjärranalys som hjälpmedel till röjningsrådgivning

Examensarbete · SLU

… of tree species etc. were registrated. To obtain data for an economic simulation of the precommercial thinning, between two and four sample plots were subjectively chosen in each object. The data collected was for instance tree hight, tree species and stem density. The National …

Grazemore DSS för att optimera utnyttjandet av bete i mjölkproduktionen :

Examensarbete · SLU

… do this, a grazing experiment was planed and performed during the summer 2005. Simulations in the DSS were run to get a suggestion of how the cows should graze, grazing calendar 1. Deviations and updates during the season resulted in the simulated grazing calendar 2. During the …

en modellstudie vid dimensionerande flöde

Examensarbete, avancerad nivå · Luleå

… values are given in the literature. For better estimations numerical simulations or laboratory flume experiments can be carried out. After some considerations, it was decided to perform a laboratory model study in scale 1:66. The modelling was initially used to estimate the …

Grundvattenmodellering i Badelundaåsen

Examensarbete, avancerad nivå · Uppsala universitet

… of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten’s investigations in Lennheden and that it also can be …

Modellering av hydrauliskt aktuatorsystem

Examensarbete, grundnivå · Linköpings universitet

… parts of the system, in order to allow calibration in more than one place. The simulation results show that the model works with consideration to the above mentioned conditions. It also works as a proof of that the software can be used for these types of applications.

Robotstyrning med metoden Sliding Mode Control

Examensarbete, grundnivå · Linköpings universitet

… To evaluate the SMC-methodology and compare it with the existing solution simulations using SMC and LQ-control are made with uncertainties and modeling imprecision. Our tests show that a control law based on SMC is robust and seems to be a very good alternative to the existing …

Automatiskt avvägningssystem för obemannad undervattensfarkost

Examensarbete, grundnivå · Linköpings universitet

… and evaluated. A part of big importance in this report is the work with simulations to predict the performance of the system and its behaviour. Other big parts has been to find suiting components and to develop the control electronics of the system.
