OBJECT DETECTION AND RECOGNITION USING R-CNN MODEL WITH OPTIMIZED SELECTIVE SEARCH ALGORITHM AND HIGH-ORDER CONVOLUTIONAL NEURAL NETWORK

This article is dedicated to the objects detection and recognition problem. The article presents the improvements that may be applied to one of the most perspective recent models R-CNN. Most of today's efficient models are not designed to work in real time, it is a great problem to the robotic systems development. The main purposes of the article are speed-up of the algorithm and the use of higher-order convolutional neural networks. In the article described improvement of selective search algorithm for reducing the number of object proposals, the experimental results on the use of high-order neurons in neural network layers, and the method of convolution neural networks speed-up with the use of vector-matrix processors. The article provides information on the possible improvements of the R-CNN model, accelerating its work without losing the object recognition quality

Stability of Citrinae Subtribe Development in the Conditions of the Mediterranean Area

Fluctuating asymmetry as the value of random deviations reflects either stability or instability of development. It is quite often used by researchers to assess the level of influence of anthropogenic and climatic factors. This study is focused on the territory with favorable climate and low anthropogenic load. The object of the study includes leaf blades of woody plants Citrus X sinensis (Valencia), Citrus limon (Molla Mehmet), Citrus reticulata (Okitsu wase C. unshiu) and Punica granatum (Emek) of the city of Kemer of the Republic of Turkey. The reliability of the presented results is justified by the use of correct methods of study and adequate statistical processing of big data. The integrated indicator of fluctuating asymmetry was the highest for leaf blades of Punica granatum (0.019), Citrus limon (0.017), these plants are introduced species. Citrus X sinensis and Citrus reticulata were characterized by low level of destabilization of plants in the conditions of the Mediterranean Area. It is shown that the most sensitive morphological features of fluctuating asymmetry for Citrinae Citrus X sinensis subtribe plants are j4 and j5, Cítrus límon – j2 and j5, Citrus reticulata – j3 and j4

STUDY OF INTERFERENCE TO IEEE 802.11N STANDARD RADIO NETWORKS

Inefficient network operation is a frequent phenomenon in many enterprises and public places. To eliminate this problem, a method was developed for allocating access points, taking into account all the factors and phenomena that affect its operation
