The article considers the possibilities of using the deep learning convolutional neural network ResNet in computer vision and image classification problems. The interpretation of the ResNet network and the datasets used for its training are presented, as well as a method for training a deep convolutional neural network with stochastic depth, which allows significantly reducing errors in the test sample.

The results of measurements of complex relative permittivity of bentonite and clayey sandstone with different degrees of salinity with low moisture are given in the range of temperatures –20° to  +105 °C at frequencies from 25 Hz to 1 GHz. It is shown, that even a small amount of water in sandy and sandy-argillaceous rocks causes an increase of the real part of complex relative permittivity at frequencies below 100 Hz. The explanation by linearly-broken dependence of refractive index on moisture is given at its small values. By a dielectric method it is shown that in the process of water film formation on the surface of a mineral, the water molecules binding energy changes. Big distinctions in low-frequency dielectric relaxation times testify to the change of binding energy of molecules of water on the surface of a mineral. Also dependences of relaxation times on temperature are various. The results of dielectric measurements showed a strong influence of the salt on the dielectric permittivity of the clay and clayey sandstone even at a low moisture level.

SummarySince November, 2012, patients with chronic lung disease, chronic heart failure (CHF) or a history of myocardial infarction have being actively vac cinated using 13 valent conjugated pneumococcal vaccine, in Chelyabinsk pulmonological centre. To December, 2013, 103 patients have been vac cinated. Safety of 13 valent conjugated pneumococcal vaccine was evaluated in all vaccinated patients. Efficacy was evaluated in 61 patients (21 with chronic obstructive pulmonary disease (COPD), 10 with bronchiectasis, 26 with COPD and asthma, and 4 with CHF. The vaccine efficacy was eval uated in a year after the vaccination. We found 4.8 fold reduction in exacerbation number in COPD patients, 4.1 fold reduction in bronchiectasis patients and 2.3 fold reduction in patients with COPD and asthma. Number of hospitalisations decreased in 9, 8 и 2.2 times, respectively; number of pneumonias decreased in 6; 4.1 and 2.3 times, respectively.

The results of experimental measurements of the complex dielectric permittivity (CDP) of sand and powders of quartz granules saturated with a saline solution with a conductivity from 0 to 0.77 S/m are presented. The measurements were carried out at the frequencies from 1 kHz to 5 GHz. It is shown that in the frequency range from 10 kHz to 100 MHz, the dielectric characteristics can be modeled by three relaxation processes. The parameters of these processes are described by the Debye and Cole-Cole formulas. For two low-frequency processes, regression equations that relate the parameters of the processes with the specific conductivity of the samples at a frequency of 5 kHz are found. Using the obtained equations and the results of CDP measuring at a frequency of 1 GHz, the calculated CDP spectra of coarse sand samples were obtained. The average deviations of the calculated data from the experimental ones were from 10 to 30 %.
