Drive-based Modeling And Visualization Of Crew Race Strategy And Performance

Cornett, Jeffrey 01 January 2008 (has links)
Crew race strategy is typically formulated by coaches based on rowing tradition and years of experience. However, coaching strategies are not generally supported by empirical evidence and decision-support models. Previous models of crew race strategy have been constrained by the sparse information published on crew race performance (quarterly 500-meter splits). Empirical research has merely summarized which quarterly splits averaged the fastest and slowest relative to the other splits and relative to the average speed of the other competitors. Video records of crew race world championships provide a rich source of data for those capable and patient enough to mine this level of detail. This dissertation is based on a precise frame-by-frame video analysis of five world championship rowing finals. With six competing crews per race, a database of 75 race-pair duels was compiled that summarizes race positioning, competitive drives, and relative stroke rates at 10-meter intervals recorded with photo-finish precision (30 frames per second). The drive-based research pioneered in this dissertation makes several contributions to understanding the dynamics of crew race strategy and performance: 1) An 8-factor conceptual model of crew race performance. 2) A generic drive model that decomposes how pairs of crews duel in a race. 3) Graphical summaries of the rates and locations of successful and unsuccessful drives. 4) Contour lines of the margins that winning crews hold over the course of the race. 5) Trend lines for what constitutes a probabilistically decisive lead as a function of position along the course, seconds behind the leader, and whether the trailing crew is driving. This research defines a new drive-based vocabulary for evaluating crew race performance for use by coaches, competitors and race analysts. The research graphically illustrates situational parameters helpful in formulating race strategy and guiding real-time decision-making by competitors. This research also lays the foundation for future industrial engineering decision-support models and associated parameters as applied to race strategy and tactics.

Analýza organizační kultury v dopravní společnosti / Analysis of the organizational culture of transport company

Kučerová, Eliška January 2016 (has links)
The aim of the thesis is to analyse the organizational culture in three local companies of the transport corporation. The analysis is carried out with the aim to map the organizational culture in the local companies. At the beginning of the work is described theory, which is composed from the organizational culture, models of individual organizational cultures and elements that may affect the strength of the organizational culture and others. In the empirical part are analysed the data obtained by various methods of diagnostics organizational culture. These include observation, interviewing and analysis the documents of company. At the end of this thesis are found the recommendations for the company.

Modelování lineárního pohonu s DC motorem pro potřeby řízení / Modelling of linear power drive with DC motor for control purposes

Vrbka, Michal January 2009 (has links)
In my diploma thesis, I developed the model of a linear actuator for the control purposes. The first part summarizes the literature research of currently available linear actuator systems. The work further describes some of the capabilities of the simulation environment Matlab which was used for the creation of the computer model of linear actuators. In the last part, this theoretical model is compared with already available physical model of the system.
