Convergent platform for multi-agent data processing in the “Smart Road” system

In the article, the multi-agent platform for convergent sensor data processing in a monitoring system for Smart Road Infrastructure are considered. The platform works with a network of spatially distributed photo-radar complexes, which in real time record road accidents. The paper discusses tools for collection of road accident’s photo and video data fixation, data mining and forecasting of transport incidents, depending on various factors (meteorological, social, operational, etc.). The results of monitoring and analysis of traffic accidents, fixed by an intelligent monitoring system with photo-radar complexes are considered. The connection between the complexes and the data processing center using a heterogeneous wireless network is established. A multi-agent approach developed to address the tasks of sensor data collecting and processing.  Convergent approach is the convergence of cloud, fog and mobile data processing technologies. The structure of the neural network is adapted to the diagnosing problems and forecasting. The tasks of intellectual analysis and forecasting traffic accidents solved. The hybrid fuzzy neural network synthesized. Because the comparison of time series of traffic accidents and time series of meteorological factors, it established that the presence of factors to become determinants for an abnormal change in the traffic situation in controlled areas. The monitoring system is a part of Smart Road Infrastructure within the framework of the Smart & Safe City concept

Measurements and simulations of wakefields at the Accelerator Test Facility 2

Wakefields are an important factor in accelerator design, and are a real concern when preserving the low beam emittance in modern machines. Charge dependent beam size growth has been observed at the Accelerator Test Facility (ATF2), a test accelerator for future linear collider beam delivery systems. Part of the explanation of this beam size growth is wakefields. In this paper we present numerical calculations of the wakefields produced by several types of geometrical discontinuities in the beam line as well as tracking simulations to estimate the induced effects. We also discuss precision beam kick measurements performed with the ATF2 cavity beam position monitor system for a test wakefield source in a movable section of the vacuum chamber. Using an improved model independent method we measured a wakefield kick for this movable section of about 0.49  V/pC/mm, which, compared to the calculated value from electromagnetic simulations of 0.41  V/pC/mm, is within the systematic error

ПЕРВЫЙ ОПЫТ ИСПОЛЬЗОВАНИЯ «КЕМАНГИОПРОТЕЗА» ПРИ ОПЕРАЦИИ NORWOOD – SANO

HighlightsThe article presents a unique clinical case of correction of hypoplastic left heart syndrome with Norwood procedure using a “KemAngioprosthesis” vascular xenograft as a Sano shunt. AbstractWe present the first successful clinical case of using the “KemAngioprosthesis” vascular xenograft in the pulmonary position as the Sano shunt in the Norwood procedure for correction of hypoplastic left heart syndrome. A newborn baby (gestation period of 38 weeks) diagnosed with congenital heart disease, and hypoplastic left heart syndrome was admitted to the Research Institute for Complex Issues of Cardiovascular Diseases. The child survived the first stage of the modified Norwood procedure (Sano shunt) using a biological vascular prosthesis. This clinical case showed that using the “KemAngioprosthesis” vascular xenograft in Norwood procedure to modify pulmonary blood flow by creating an anastomosis between the right ventricle and bifurcation of the pulmonary artery is effective and safe in the short-term period.Основные положенияВ статье представлен уникальный случай гемодинамической коррекции синдрома гипоплазии левых отделов сердца. При операции Norwood в качестве шунта Sano использован сосудистый ксенографт «КемАнгиопротез» (ЗАО «НеоКор», Кемерово). АбстрактПредставлен первый успешный опыт применения артериального аутографта «КемАнгиопротез» в легочной позиции при операции Norwood – Sano, направленной на гемодинамическую коррекцию синдрома гипоплазии левого желудочка. В НИИ КПССЗ поступил новорожденный со сроком гестации 38 нед. с диагнозом: врожденный порок сердца, синдром гипоплазии левых отделов сердца. Ребенку успешно выполнен первый этап гемодинамической коррекции методом Norwood – Sano с использованием биологического сосудистого протеза. Данный клинический случай показал, что применение «КемАнгиопротеза» при операции Norwood – Sano для модификации легочного кровотока путем создания анастомоза между правым желудочком и бифуркацией легочной артерии является эффективным и безопасным в госпитальном периоде

Layered structures mechanical properties assessment by dynamic tests

An effective method of the layered structures mechanical properties determination is presented. The method is based on the non-stationary analysis of the structure response that is acted by impact load on the surface of multi-layered structure. The assessment of the design parameters using a genetic algorithm is performed. During the solving procedure there are several methods for breeding and selection processes are used, that demonstrated different results. The most appropriate parameters for described algorithms are selected and analysed

Comparison of the efficiency of neural network algorithms in recognition and classification problems

The article is devoted to the problem of comparing the effectiveness of feedforward (FF) and convolutional neural networks (CNN) algorithms in the problems of handwritten digit recognition and classification. In recent years, the attention of many researchers to the FF and CNN algorithms has given rise to many hybrid models focused on solving specific problems. At the same time, the efficiency of each algorithm in terms of accuracy and labour intensity remains unclear. It is shown that in classical problems, FFs can have advantages over CNN in terms of labour intensity with the same accuracy of results. Using the handwritten digits data from the MNIST database as an example, it is shown that FF algorithms provide greater accuracy and require less computation time than CNN

The article presents a comprehensive method for diagnosing underground structures using the example of an underground pedestrian crossing located in Rostov-on-Don. The problem of assessing the condition of buildings and structures is very relevant at all stages of the life cycle. There is a special need for continuous monitoring of bearing structures for many buildings with critical applications especially if reliability of which determines the life and health of people. This work considered complex method included geodetic research, geological study of the state of sub-soil, analysis of state of steel and reinforced concrete structures, vibro diagnostics of load-bearing structures under dynamic technogenic impacts and an assessment of the mechanical characteristics of steel and reinforced concrete structures in order to develop a conclusion on the overall state of the transition and the possibility of its further operation. Analysis of the response from arbitrary non-stationary effects on structural elements is carried out on the base of the calculated spectrum of reference impacts
