Integration of XFOIL software in MATLAB environment

Práce se zabývá programem, který je schopný spouštět a řídit XFOIL z prostředí MATLABu. Tento program je zaměřen hlavně na hormadné zpracování dat a vykreslení výsledků z výpočtu XFOILu do grafů. Práce se také zabývá stručným popisem XFOILu a MATLABu, popisem charakteristik profilu a podobnostních čísel používaných XFOILem při výpočtu.Thesis is concerned with program which is able to run and control XFOIL from MATLAB environment. This program is focused on bulk data processing and plotting of XFOIL results. Thesis is also concerned with brief description of XFOIL and MATLAB, description of profile characteristics and comparison numbers used in calculation by XFOIL.

Using Computer Support when Dealing with Pre Crash Vehicle Movements

Práce se zabývá porovnáním vlivu zvolené metody řešení na předstřetový pohyb v rámci jednoho simulačního programu a na rozdíly ve výpočtu pro jednu metodu ve dvou různých programech. Porovnávané metody řešení jsou kinematický a dynamický výpočet předstřetového pohybu, porovnávané programy jsou Virtual CRASH a PC-Crash.Thesis deals with comparison of influence of chosen solution method on pre crash movement of vehicles in one simulation program and on differences between calculations for one method in different programs. Compared solution methods are kinematics and dynamics solutions of pre crash movement, compared programs are Virtual CRASH and PC-Crash.

Obsolete or Viable? Revision of Lane-Change Manoeuvre Duration Empirical Calculation

This study presents a calculation of the time required to execute a lane-change manoeuvre. Compared with other (and older) calculation methods, an analysis was conducted to determine which approach could yield the most reliable results. This study aimed to present a universal calculation method for different road surfaces, surface conditions (dry and wet road surface), and vehicle types (i.e., from small vehicles to SUVs). A total of 108 comparable manoeuvres with modern vehicles were used as a basis for statistical analysis. A new mathematical constant was found based on a regression analysis, adjusting one of the older calculation methods (so-called Kovařík equation), providing the best match between real and calculated manoeuvre duration

Driver’s behavior while passing through pedestrian crossing analysis

The article deals with analysis of 8 drivers’ behavior while driving through pedestrian crossing during dusk and night. Monitored vehicle passes through modern crosswalk in urban area that is marked with horizontal and vertical road signs. The crossing is illuminated from left side from the direction of travel. Pedestrian is protected with safety island, which is marked with “passing on the right” mandatory sign, in the middle of the road. Optical reactions on various stimuli are monitored while driving with the help of the specialized device Viewpointsystem®, GmgH for monitoring changes of driver’s viewing angle. Drivers’ behavior strategies when passing the crosswalk are compared in this thesis. Monitored are driver’s navigation while driving and his reaction on the crossing pedestrian. Dangerousness of each driving situation is assessed and each strategy is evaluated. Results of this analysis are based on extensive driving tests that were realized in close cooperation of Institute of Forensic Engineering, University of Technology in Brno and research institute EPIGUS – Institut für ganzheitliche Unfall- und Sicherheitforshung from Austria in year 2010
