Advantages And Disadvantages Of Professional Preparation Of The Future Fitness Trainers In Great Britain And Australia

Analysis of scientific literature and documental sources testifies to actualization of problem of professional preparation of the future fitness trainers at educational level “bachelor” in different countries. The special features of professional education of these specialists in Great Britain and Australia were determined. To the advantages of preparation can be assigned the flexible character of stage education and possibility to work as a fitness-trainer, having the second, third, fourth and fifth levels according to Qualification Credit Framework – QCF. The sixth level is equal to educational level “bachelor”. Educational institution that realizes preparation at sixth level on specialization "Personal Fitness Training" is University of Central Lancashire. The content of university curriculum provides mastering by students of competences on psychology of communication, motivation, leadership, nutritiology, management, medical rehabilitation and so on. From our point of view, disadvantage of professional preparation of the future fitness-trainers in Great Britain and Australia is the excessive applied orientation of teaching and absence of cultural disciplines

Noise Method of Electrical Resistance Measuring for Testing of Motion Control Systems

Designed the method of measuring the electrical resistance of conductive material using its own thermal noise without the transmittance of electrical current through it that excludes the materials heating and other negative effects

Nonequilibrium transport equations and ab initio study of adsorption processes on carbon nanotubes

In a theoretical study of gas adsorption on carbon nanotubes (CNT) nonequilibrium processes of ionization, polarization, surface diffusion and desorption of atoms are considered self-consistently. The approach is based on Zubarev's method of nonequilibrium statistical operator and reaction-diffusion theory. The set of nonlinear transport equations are obtained for the chosen parameters of description: the average numbers of adsorbed atoms, ionized and polarized atoms in the electromagnetic field of CNT, and the average number of atoms desorbed from the CNT surface. Ab initio simulations are conducted for a "gas-single wall carbon nanotube" system for gases of particular practical interest: He and NO. The obtained values of adsorption energy reveal preferable localization sites of absorbed He atoms as well as their dependency on adsorption distances. A significant effect of NO adsorption on CNT electronic properties is demonstrated. The effect of presence of vacancies on adsorption nature is analyzed. It is shown that under the influence of vacancy formation the CNT structure undergoes reconstruction that enables chemisorption of NO molecules.Comment: 12 pages, 4 figure

Testing System for Unmanned Aerial Vehicles Microelectromechanical Sensors

Designed system for microelectromechanical sensors testing before use them in the unmanned aerial vehicles navigation systems. Microelectromechanical sensors pressure and temperature sensor, magnetic field sensor and inertial unit were studied. Experimental results shows that designed testing equipment allows to calibrate microelectromechanical sensors without necessity of performing test flights that reduces the risk of unmanned aerial vehicles damaging in case of significant measurement errors

Statistical description of electrodiffusion processes in the electron subsystem of a semibounded metal within the generalized jellium model

Based on the calculation of the quasiequilibrium statistical sum by means of the functional integration method, we obtained a nonequilibrium statistical operator for the electron subsystem of a semibounded metal in the framework of the generalized jellium model in the Gaussian and higher approximations with respect to the dynamic electron correlations. This approach allows one to go beyond the linear approximation with respect to the gradient of the electrochemical potential corresponding to weakly nonequilibrium processes and to obtain generalized transport equations that describe nonlinear processes.Comment: 13 page

Machine learning technique for morphological classification of galaxies at z<0.1 from the SDSS

Methods. We used different galaxy classification techniques: human labeling, multi-photometry diagrams, Naive Bayes, Logistic Regression, Support Vector Machine, Random Forest, k-Nearest Neighbors, and k-fold validation. Results. We present results of a binary automated morphological classification of galaxies conducted by human labeling, multiphotometry, and supervised Machine Learning methods. We applied its to the sample of galaxies from the SDSS DR9 with redshifts of 0.02 < z < 0.1 and absolute stellar magnitudes of 24m < Mr < 19.4m. To study the classifier, we used absolute magnitudes: Mu, Mg, Mr , Mi, Mz, Mu-Mr , Mg-Mi, Mu-Mg, Mr-Mz, and inverse concentration index to the center R50/R90. Using the Support vector machine classifier and the data on color indices, absolute magnitudes, inverse concentration index of galaxies with visual morphological types, we were able to classify 316 031 galaxies from the SDSS DR9 with unknown morphological types. Conclusions. The methods of Support Vector Machine and Random Forest with Scikit-learn machine learning in Python provide the highest accuracy for the binary galaxy morphological classification: 96.4% correctly classified (96.1% early E and 96.9% late L types) and 95.5% correctly classified (96.7% early E and 92.8% late L types), respectively. Applying the Support Vector Machine for the sample of 316 031 galaxies from the SDSS DR9 at z < 0.1, we found 141 211 E and 174 820 L types among them.Comment: 10 pages, 5 figures.
