Caos no trilho de ar: instrumentação para uma experiência didática / Chaotic behavior of a glider on air track: instrumentation for a didactic experiment

Rubens Bernardes Filho 24 August 1992 (has links)
Neste trabalho estuda-se a interação, através de choques, entre um oscilador harmônico e um carro de trilho de ar inclinado, análogo ao sistema descrito na literatura como \"bouncing-ball\". A análise teórica e a simulação prevêem estabilidade e bifurcação nas fases do oscilador em que ocorrem os choques, confirmados pela experiência. As simulações indicam a ocorrência de caos, fato que foi confirmado experimentalmente. O sistema experimental de aquisição de dados produzido permite a utilização no ensino de graduação. Os dados experimentais gerados pelo sistema são coletados por uma interface de aquisição, que trabalha acoplada a um microcomputador Apple II, e transferidos para um microcomputador tipo IBM-PC, possibilitando uma análise rápida dos resultados obtidos. Para a visualização das regiões de estabilidade, de bifurcação e do atrator estranho, que surge na região de caos, foram desenvolvidos programas gráficos e de cálculo, que permitem, também, realizar uma avaliação da dimensão do atrator. Os programas de simulação permitem ao aluno realizar cálculos e gerar gráficos, variando os parâmetros de controle do sistema. No experimento foi utilizado coeficiente de restituição E de 0,22 e a dimensão fractal encontrada para o atrator foi 1,2. / In the present dissertation the interaction between an harmonic oscillator and an air track\'s glider is studied, analogous to the system described in literature as the bouncing-ball. Theoretical analysis and simulation predict stability and bifurcation in the phases of the oscillator in which occur collisions. The simulations indicate the occurrence of chaos, a fact confirmed experimentally. The built up experimental data acquisition system can be used in undergraduate teaching. Experimental data generated by the system are collected by na acquisition interface, which works linked to an Apple II microcomputer, and are transferred to an IBM-PC type microcomputer, allowing quick analysis of the obtained results. To visualize the regions of stability, of bifurcation and of the strange attractor, graphic and calculation programs were developed, which also permit an evaluation of the attractor\'s dimension. The simulation programs allow the student to do calculations and generate graphs, while varying the system\'s control parameters. In the experiment a restitution coefficient E of 0.22 was used and the found fractal dimension for the attractor was 1.2.

Relaxation training, flexibility training, and their relationship to running speeds at short distances

Thompson, Robert Charles 01 January 1978 (has links)
The purpose of this investigation was to determine the relationship of relaxation training and flexibility training to running speeds of high intensity at three short distances for high school males. In addition to the main problem, the following sub-problems were established: (1) Was there a significant difference of effects between the relaxation training and the flexibility training on times at the three distances of 20, 50, and 100 yards? (2) Was the relationship of flexibility and relaxation to running speed the same as the distance increased? (3) Did a combination of flexibility and relaxation training produce different results then relaxation training of flexibility training alone?

An Evaluation of the Effects of a Student Trajectory Enhancement Program (STEP UP) on High School Performance

Pritchard, Odalys G. 02 July 2019 (has links)
The Student Trajectory Enhancement Program (STEP UP) was launched in 2014 by Hillsborough County Public Schools (HCPS) as a six-week summer program that targeted over-age, retained, potentially under-achieving students completing the sixth grade. The purpose of this study was to conduct a summative evaluation of the effectiveness of the STEP UP program in keeping program participants “on track” for high school graduation and to determine if the intended goals of the program were realized. STEP UP was developed in response to compelling data that there is an unacceptably high number of overage students in middle school in HCPS. STEP UP was intended to decrease the number of potential dropouts in HCPS, with the assumption that a number of students who drop out of high school originate as overage students in the elementary and middle grades. The evaluation focused on students who participated in the initial cohort in the summer of 2014. Data analyzed were students’ attendance, behavior, course performance, and grade point averages—the district’s Key Performance Indicators (KPI’s) serving as the benchmark for determining whether students are “on track” to graduate. Findings of the study suggested that students’ “on-track” performance on individual KPI metrics was significantly higher than the overall “on-track” performance on all Key Performance Indicators as an aggregate. Data reflected that the majority of students in the program were minority (78.74%), designated as Free/Reduced Lunch (91.27%), and classified as ESE and ELL (54.09%). Of the variables studied (ethnicity, gender, ESE status, ELL status, and FRL status), students in poverty and students with profound exceptionalities had the lowest “on-track” performance rates. While there were differences in individual KPI performance rates among ethnic groups, there was little difference among the three largest ethnic subgroups in the data set (Hispanic, white and African-American) when analyzing “on-track” performance rates for all KPI’s together. This study contributes to the school district’s ability to make improvements to the program. In addition, other districts might gain insights to help them determine if a similar program could prove beneficial for their overage, retained students in middle school.

Vyhledávání a sledování objektů autonomním dronem / Search-and-Track Techniques for Autonomous Drone

Patík, Vladimír January 2020 (has links)
In this diploma thesis we are proposing solution for the search and track problem an evading ground object by an air pursuer in a 3D environment. In addition to static obstacles, there may be dynamic obstacles in the environment which are not plotted on the map provided to the drone. In order to avoid a collision, a safety method has been proposed which is based on processing the image from the input camera by a neural network. The tracking subtask is solved by a reactive algorithm adapted for movement in a built-up area. The probabilistic search algorithm is based on solving Art Gallery and Orienteering problems using nature-inspired algorithms. All algorithms and procedures are evaluated in a simulated environment on randomly generated maps.
