Analysis of two streaming frameworks: Apache Storm and IBM InfoSphere Streams was performed in solving a multiple object detection task. The analysis focused on two parameters: throughput and 95th percentile of image processing delay. Faces were chosen as the objects to be detected. Profiling was held under CentOS operating systems running on a five node cluster. Face detection was performed using an OpenCV cascade classifier. First architectures and the experiment description were covered. Final suggestions on the applicability of the two systems were made in the concluding section of the article. Apache Storm demonstrated a scalability advantage over IBM InfoSphere Streams in the experiment conducted. It was confirmed that the system based on Apache Storm was able to operate on FullHD video in real-time, achieving throughput of 24 images per second on the hardware used.

In this paper we propose and numerically investigate an all-optical temporal integrator based on a photonic crystal cavity. We show that an array of photonic crystal cavities enables high-order temporal integration. The effect of the value of the cavity’s free spectral range on the accuracy of the integration is considered. The influence of the coupling coefficients in the resonator array on the integration accuracy is demonstrated. A compact integrator based on a photonic crystal nanobeam cavity is designed, which allows high-precision integration of optical pulses of subpicosecond duration.

Article is devoted to simulation of hyperspectrometer based on the use of linear variable filters. We regarded possibilities of recovery of spectral pixels of images based on the solution of the integral equation. The paper presents estimates of the size of the scattering spots depending on the parameters of the spectral filter. Numerical results showed that a significant deterioration in resolution occurs only in the case of short-optical systems.

Comparison of two streaming systems: Apache Storm and IBM InfoSphere Streams was performed in solving image sliding window filtering task. Analysis was focused on two parameters: throughput and memory consumption. Profiling was held under CentOS operating systems running on two virtual machines for each system. First, the most cheap in developing cost realizations were compared. After analysis optimization of memory consumption was performed.  Final suggestions on applicability of two systems were made at the end of the article.

We considered comparative modeling action of a hyperspectrometer based on the Offner scheme including prisms or a diffraction grating within the geometrical optics. It is shown that the use of a diffraction grating instead of a prism results in a more uniform spread of the spectral components of the dispersed image.

We discuss the simulation of a hyperspectrometer based on the use of linear variable filters. The possibility of recovery of the image spectral pixels through the solution of the integral equation is considered. Estimates of the scattering spot size as a function of the spectral filter parameters are obtained. The numerical results show that a significant deterioration in resolution occurs only in the case of short-focus optical systems.

The ability of general optical resonators to perform differentiation of optical signals in time. Analytical dependencies for such resonators are obtained with temporal coupled wave theory. A compact nanocavity-aided differentiator based on ridged photonic-crystal waveguide is designed.

Разработан и программно реализован алгоритм решения стационарного уравнения Шрёдингера для сложного кусочно-постоянного потенциала при наличии электрического поля. Алгоритм основан на последовательной сшивке решений в виде функций Эйри на границах зон без повышения ранга матрицы более двух, что позволяет получить характеристическое уравнение в удобной для поиска корней форме. Разработанный алгоритм позволяет получать корректные решения при значениях приложенного электрического поля, превышающих величину основного энергетического уровня, т.е. в условиях, когда не применим метод возмущений.

We propose an improved version of the earlier developed optical arrangement for forming inhomogeneously polarized laser radiation on the basis of the sum of two circulary polarised beams. One of these beams has right circularly polarization, and another–left, besides these beams has the phase vortices of opposite signs. DOE s for generating higher-order cylindrical beams was calculated and fabricated . In the experiments, the quality of the resulting beams is shown to be improved.
