Biomechanika šlapání jako předpoklad výkonu v cyklistické části triatlonu / Biomechanics of pedaling as a determinant for the performance in the cycling part in the triathlon

Svatoš, Václav January 2012 (has links)
Tittle: Biomechanics of pedaling as a determinant for the performance in the cycling part in the triathlon Objective: Prove that mastering pedaling technique, means higher performance in triathlon. Method: For the analysis of measured data use software SPSS, in which we use the test for two independent (paired) files. Due to the characteristics of the file, we used the Mann- Whitney test, we set the significance level at 0.05. Then we set standards for the selected test using T-points. Results: On the basis of the hypotheses, we conclude that there satisticky significant difference between groups (selection, other) the test results in the men's category (sig. 0.019). The opposite results were observed in the women's category (sig. 0.683). Performance comparison groups of men and women were different and statistically highly significant (sig. 0.000). Another result of this work is to establish standards by T - points for members of the youth sports center (YSC) in the triathlon for the assessment test at maximum cadence bicycle ergometer test in Cyclus 2. Keywords: pedaling cadence, YSC, diagnostics, maximum pedaling cadence test, Mann- Whitney test

An Analysis of Fourier Transform Infrared Spectroscopy Data to Predict Herpes Simplex Virus 1 Infection

Champion, Patrick D 20 November 2008 (has links)
The purpose of this analysis is to evaluate the usefulness of Fourier Transform Infrared (FTIR) spectroscopy in the detection of Herpes Simplex Virus 1 (hsv1) infection at an early stage. The raw absorption values were standardized to eliminate inter-sampling error. Wilcoxon-Mann-Whitney (WMW) statistic's Z score was calculated to select significant spectral regions. Partial least squares modeling was performed because of multicollinearity. Kolmogorov-Smirnov statistic showed models for healthy tissues from different time groups were not from same distribution. The additional 24 hour dataset was evaluated using the following methods. Variables were selected by WMW Z score. Difference of Composites statistic, DC, was created as a disease indicator and evaluated using area under the ROC curve, specificities, and confidence intervals using bootstrap algorithm. The specificity of DC was high, however the confidence intervals were large. Future studies are required with larger sample sizes to test this statistic's usefulness.

Intresse för liv i rörelse : En studie av ungdomars motiv till att vara fysiskt aktiva och motiv att inte vara fysiskt aktiva

Dahlström, Marcus January 2017 (has links)
Syfte och Frågeställning Syftet med denna studie var att undersöka gymnasieungdomars motiv i form av motivområden för att vara fysiskt aktiva respektive för att inte vara fysiskt aktiva. Frågeställningarna var: (1) Vilka motivområden har stark anknytning till att vara fysiskt aktiv respektive inte vara fysiskt aktiv och (2) Finns det någon signifikant könsskillnad i något av motivområdena? Metod 105 ungdomar (47 flickor och 58 pojkar) i åldern 16-22 år från en gymnasieskola i västra Stockholmsområdet besvarade två enkäter med påståenden om motiv till att vara fysiskt aktiv respektive inte vara fysiskt aktiv. Motiven delades in i 11 motivområden och därefter genomfördes en deskriptiv analys i samband med elimineringen av extremvärden där man undersökte hur stark anknytning varje motivområde hade till att vara fysiskt aktiv respektive inte vara fysiskt aktiv. Ett Mann Whitney U test genomfördes för att undersöka om det fanns någon signifikant könsskillnad (p=0,05). Resultat Motivområdena Välbefinnande kortsiktigt, Välbefinnande långsiktigt, och Lugnande motiv hade stark anknytning till att vara fysiskt aktiv. Även om det inte förekom någon stark anknytning i något av motivområdena till att inte vara fysiskt aktiv, så hade Tidsrelaterade motiv starkast anknytning för både flickor och pojkar. Resultatet visade även att Tävlingsmotiv var ett starkare motiv för pojkarna än flickorna för att vara fysiskt aktiv (p=0.003) samt att Hälsorisker som motiv var ett starkare motiv för flickorna än pojkarna (p=0,041) för att inte vara fysiskt aktiv. Slutsats Resultatet i den här undersökningen gav indikationer att vissa motiv kan påverka varför gymnasieungdomar är fysiskt aktiva samt varför de inte är fysiskt aktiva, men resultaten löper stor risk för att bero på slumpen på grund av massignifikansproblematiken. Motiv till att inte vara fysiskt aktiv hade i samtliga fall lägre medianvärden än motiv till att vara fysiskt aktiv.

Developing a new transformatory cultural tourism experience model / Milena Ivanovic

Ivanovic, Milena January 2014 (has links)
The research question addressed by this thesis is: To what degree the results of the statistical analysis will corroborate the main theoretical assumptions of the proposed theoretical model of new authentic transformatory cultural tourism experience as transmodern phenomenon of equality of two Cartesian levels of reality, material (objective authenticity) and experiential (constructive authenticity) in informing the intrapersonal existential authenticity as outcome transformatory tourist experience. The main reason for undertaking this study is to resolve the evident crisis of postmodern authenticity discourse arising from a failure of postmodern theoretical framework to integrate three social authenticity theories into a coherent authenticity discourse. The research design adopted in the study is theory-testing theory-building paradigm which incorporates both deductive and inductive logic and was applied in three successive phases. In the first phase the new theoretical model of transformatory cultural tourism experience was proposed, underpinned by transmodern flat ontology and philosophy of the Speculative Realism. In the second phase the main theoretical assumptions of equal contribution of objective and constructive authenticity as independent variables in informing the transformatory experience as dependent variable were empirically tested by standard multiple regression analysis. In the last deductive phase the results of all empirical tests were inferred onto initial theoretical assumptions of the original model and new modified model of transformatory cultural tourism experience has been proposed with an addition of two newly identified transmodern experiential constructs, epistemological and ontological authenticity. For a primary data collection the instrument was a self-administered questionnaire and the sampling strategy was a non-probability sampling. The data was collected during the period 01st and 18 April 2011 at two sites, Constitution Hill and Hector Peterson Memorial in Johannesburg. The sample size from two sites was N=406. The scales of measurements were already developed in the earlier questionnaire and the confirmatory factor analysis was used to confirm the variables contained in each factor, namely objective and constructive authenticity as independent variables and transformatory experience as the dependent variable. The results of a standard multiple regression analysis confirmed the importance of the model as independent variables explained 30.7% of the variances (R2=.307) in the model. An unexpected result was that objective authenticity explained 34.5% of the variance in the model (β = .345) which is significantly higher than 30.5% of variance explained by constructive authenticity (β = .305). The results of standard multiple regression analysis confirmed the main theoretical assumption of the model of equality of material and experiential levels of Cartesian duality in informing the new transformatory experience regarded as a transmodern phenomenon. The standard, stepwise and hierarchical multiple regression tests were further conducted to establish if any moderating variables should be added into the original model containing two independent variables. The tests included five demographic variables (gender, place of residence, connection with culture, and two items of education (pre-tertiary education and Bachelors degree) and none of the variables explained a level of variability which warranted their inclusion into the model. Consequently, the results of the retests of the model did not change its initial conceptualisation. Finally, the t-test and Mann-Whitney U tests identified a significant difference between the two groups in the level of authenticity of their experience derived from two sites. A group having stronger inclination for authenticity is identified as Cultural Creatives, who are known as the forerunners of transmodernism. Based on the results of all statistical tests the final model was modified to reflect the important theoretical findings pertaining to two new types of transmodern authenticity. Epistemological authenticity denotes combined effects of objective and constructive authenticity in feeding the ontological authenticity of transformatory experience. The ontological authenticity is further identified as a confirmation of authentic-self which is required by Cultural Creatives. With proposition of new modified model the theory-testing theory-building research design came to its conclusion. The importance of research findings presented in this study lies not only in resolving the current crises of authenticity discourse in tourism but in the proposed New theoretical and conceptual model of transformatory cultural tourism experience underpinned by objective ·and constructive authenticity which will open a whole new field in tourism research arising from new transmodern experiential paradigm. / PhD (Tourism Management), North-West University, Potchefstroom Campus, 2014

Vývoj odtoku vody ve vybraných povodích Kyrgyzského hřbetu, Ťan-Šan / Runoff development in selected catchments in the Kyrgyz Range, Tian-Shan

Jedličková, Šárka January 2019 (has links)
The main objective of this paper was to investigate runoff changes in the catchment Ala-Arca, Alamaedin and Kara-Balta in Kyrgyzstan, as well as change in climate conditions from available stations in the area. The runoff, precipitation, and temperature series were subjected to monthly, seasonal and annual analyses based on available data. Both absolute and relative data homogeneity were verified using statistical tests such as the Mann-Whitney-Pettit test, the SNHT test, and the WiIlcoxon's two- sample test for absolute homogeneity, and the Alexandersson's test for relative homogeneity. The Mann-Kendall test was used to determine the trend in each serie. There were inhomogeneities found in a number of runoff data. In most cases, the changes of rivers Ala-Arca and Kara-Balta were recorded in 1987. Compare to Ala-Arca and Kara-Balta, the changes of river Alamedin were recorded 3 years later, in 1990. There was a positive trend development by the rivers with the glacial-snow regime. However, there was no statistically significant trend for the entire time series. Key words: runoff change, precipitation, temperature, glacial-snow regime, snow-glacial regime, homogenization, Mann-Whitney-Pettit test, trend, Mann-Kendall test, glaciation, Kyrgyzstan, Tien- Shan

Aplikace statistické analýzy řeči pacientů s Parkinsonovou nemocí / Application of statistical analysis of speech in patients with Parkinson's disease

Bijota, Jan January 2016 (has links)
This thesis deals with speech analysis of people who suffer from Parkinson’s disease. Purpose of this thesis is to obtain statistical sample of speech parameters which helps to determine if examined person is suffering from Parkinson’s disease. Statistical sample is based on hypokinetic dysarthria detection. For speech signal pre-processing DC-offset removal and pre-emphasis are used. The next step is to divide signal into frames. Phonation parameters, MFCC and PLP coefficients are used for characterization of framed speech signal. After parametrization the speech signal can be analyzed by statistical methods. For statistical analysis in this thesis Spearman’s and Pearson’s correlation coefficients, mutual information, Mann-Whitney U test and Student’s t-test are used. The thesis results are the groups of speech parameters for individual long czech vowels which are the best indicator of the difference between healthy person and patient suffering from Parkinson’s disease. These result can be helpful in medical diagnosis of a patient.
