Vztah mezi vybranými specifickými a obecnými ukazateli silových schopností závodníků ve vodním slalomu v kategorii C1 / Relationship between selected specific and general indicators of strenght in white water slalom competitors in C1 men categoryŘíha, Martin January 2018 (has links)
Title: Relationship between selected specific and general indicators of strength in water slalom competitors in category C1 Objectives: The aim of the study was to find out the relationship between the maximum strength tests at the gym and the explosive force test when paddling on flat water. Another aim of the thesis was to compare the measurement with results in selection races to Czech national team 2018. Methods: The test battery for general force tests included the bench press test, the attachment on the bench, the one arm attachment on the bench and the one arm pull up on the bar. To test the explosive force on a flat water we used a three-axis piezoelectric load cell 9137. Dewesoft Sirirus and Dewesoft, Dewetron, were used to diagnose the course of force. Correlation analysis was used to determine the relationship between the measurements. The degree of dependence was determined by the correlation coefficient value. Results: A strong dependence rate (r = ≥ 0.7) was demonstrated in the water test and the one arm attachment on the bench. There was no evidence of a strong degree of dependence on bench - press exercises (r = 0,63), the attachment on the bench (r = 0,58)and the one arm pull up on the bar (r = 0,04). The paddlers who achieved the best results in specific and general strength...

Analysis of Accuracy for Engine and Gearbox SensorsDogantimur, Erkan, Johnsson, Daniel January 2019 (has links)
This thesis provides a standardized method to measure accuracy for engine and gearbox sensors. Accuracy is defined by ISO 5725, which states that trueness and precision need to be known to provide a metric for accuracy. However, obtaining and processing the data required for this is not straight forward. In this thesis, a method is presented that consists of two main parts: data acquisition and data analysis. The data acquisition part shows how to connect all of the equipment used and how to sample and store all the raw data from the sensors. The data analysis part shows how to process that raw data into statistical data, such as trueness, repeatability and reproducibility for the sensors. Once repeatability and reproducibility are known, the total precision can be determined. Accuracy can then be obtained by using information from trueness and precision. Besides, this thesis shows that measurement error can be separated into error caused by the sensors and error caused by the measurand. This is useful information, because it can be used to assess which type of error is the greatest, whether or not it can be compensated for, and if it is economically viable to compensate for such error. The results are then shown, where it is possible to gain information about the sensors’ performance from various graphs. Between Hall and inductive sensors, there were no superior winner, since they both have their strengths and weaknesses. The thesis ends by making recommendations on how to compensate for some of the errors, and how to improve upon the method to make it more automatic in the future.
