Urgency of the research. Flight safety is an actual practical issue which solving influences the future of Ukraine as a transport state. As a consequence of technical progress aviation technology is becoming more and more sophisticated and reliable. However, the intensity of the impact on a person caused by various adverse factors, including information overloads, is constantly increasing. Statistics show that up to 80% of accidents and disasters occur due to pilot errors. The reason for about 35 % of these errors is lack of professional training, and about 40% of the errors are caused by inexperience of the crew. Target setting. The cost of aircraft, crew training and the "price" of error increase simultaneously. Cost of professional training of helicopter crews on complex flight simulators is an order of magnitude lower than on real helicopters. Therefore, today the focus of increasing the safety of flights is to improve the level of flight training and flight experience via the use of flight simulators with a high level of information adequacy to a real helicopter. Actual scientific researches and issues analysis. In order to ensure the possibility of the trained crew to obtain the appropriate official documents stating their professional training level, the simulator must be certified according to national and international requirements, i.e. the adequacy of its handling qualities to the appropriate qualities of a simulated helicopter must be guaranteed. Uninvestigated parts of general matters defining. The equipment allows simulating the conduct of the helicopter in all flight modes, including critical ones: control failure, landing in the mode of main lift rotor autorotation, etc., developing practical recommendations for the flight crew, as well as to train the flight crew to find ways out of emergencies. Receiving information about the flight mode, the parameters of the onboard systems, the external environment, etc., the crew envision the information flight model. The information model of the simulator should be as similar as possible to the information model of the real helicopter. Consequently, the basic components of the simulator are the imitation systems providing the influence of the information creating the adequate picture of the flight on sense organs of the crew, including eyesight – a visualization system, flight control equipment, etc.; hearing – a system of aviation noise simulation; vestibular apparatus – a motion generation system; tactile channel – a system for loading control levers. The research objective. The listed systems form the informational model of the simulator, which should be coordinated with the movement of the helicopter. A mathematical model of the helicopter movement dynamics and the models of the mentioned systems provide this coordination. To provide the operation of the complex flight simulator, nonlinear mathematical models of helicopter dynamics based on the modified discrete vortex method have been developed. The models describe the flow of the volumetric design of the propeller apparatus and allow simulating a real-time flight in different modes, including "post-stall" condition. The statement of basic materials. The principles and approaches to the qualification evaluation of complex flight helicopter simulators in accordance with the requirements of the EU (CS-FSTD (H)) and IKAO (Doc 9625) are analyzed. The performance capabilities of a complex full-flight Mi-171 helicopter simulator created by SPA "AVIA" are described. The necessity of certification of flight simulators in compliance with international standards is substantiated. The analysis of the validation procedure is performed. The structure and functioning of the software complex designed to automate validation tests are described. Conclusions. An algorithm for obtaining a conclusion on the test result for one of the tests is presented.

Testo completoAbstract (sommario):
To enhance the effect of motion detection, a Gaussian modeling algorithm is proposed to fix holes and breaks caused by the conventional frame difference method. The proposed algorithm uses an improved three-frame difference method. A three-frame image sequence with one frame interval is selected for pairwise difference calculation. The logical “OR” operation is used to achieve fast motion detection and to reduce voids and fractures. The Gaussian algorithm establishes an adaptive learning model to make the size and contour of the motion detection more accurate. The motion extracted by the improved three-frame difference method and Gaussian model is logically summed to obtain the final motion foreground picture. Moreover, a moving target detection method, based on the U-Net deep learning network, is proposed to reduce the dependency of deep learning on the number of training datasets. It helps the algorithm to train models on small datasets. Next, it calculates the ratio of the number of positive and negative samples in the dataset and uses the reciprocal of the ratio as the sample weight to deal with the imbalance of positive and negative samples. Finally, a threshold is set to predict the results for obtaining the moving object detection accuracy. Experimental results show that the algorithm can suppress the generation and rupture of holes and reduce the noise. Also, it can quickly and accurately detect movement to meet the design requirements.

The surface electromyography (sEMG) signal is widely used as a control source of the upper limb exoskeleton rehabilitation robot. However, the traditional way of controlling the exoskeleton robot by the sEMG signal requires one to specially extract and calculate for complex sEMG features. Moreover, due to the huge amount of calculation and individualized difference, the real-time control of the exoskeleton robot cannot be realized. Therefore, this paper proposes a novel method using an improved detection algorithm to recognize limb joint motion and detect joint angle based on sEMG images, aiming to obtain a high-security and fast-processing action recognition strategy. In this paper, MobileNetV2 combined the Ghost module as the feature extraction network to obtain the pretraining model. Then, the target detection network Yolo-V4 was used to estimate the six movement categories of the upper limb joints and to predict the joint movement angles. The experimental results showed that the proposed motion recognition methods were available. Every 100 pictures can be accurately identified in approximately 78 pictures, and the processing speed of every single picture on the PC side was 17.97 ms. For the train data, the mAP@0.5 could reach 82.3%, and mAP@0.5–0.95 could reach 0.42; for the verification data, the average recognition accuracy could reach 80.7%.

In order to effectively detect and monitor athletes and record various motion data of targets, the study suggests a study of target tracking algorithms to detect the direction of motion video sports movement based on the neural network. A class of feedforward neural networks with convolutional computation and deep structure is one of the representative algorithms of deep learning. Firstly, the athlete image is obtained from the video frame; combined with the nonathlete image to construct the training set, use the bootstrapping algorithm to train the convolutional neural network classifier. In the case of input picture frames, pyramids of different scales are then constructed by subsampling, and the location of many candidate athletes is detected by a neural network of disruption. Finally, these centers calculate the center of gravity of the athletes, find the athlete to represent the candidate, and determine the location of the final athlete through a local search process. The results of the experiment show that the proposed scheme of 6000 frames in the two game videos is compared with the AdaBoost scheme, and the detection rate of the proposed scheme is 75.41% to calculate the average detection accuracy and false alarm speed of all players. The detection rate is higher than the AdaBoost scheme. Therefore, this scheme has a high detection rate and low false positives.

We present HoldPass, the first system that can authenticate a user while they simply hold their phone. It uses the heart activity as biometric trait sensed via the hand vibrations in response to the cardiac cycle - a process known as ballistocardiography (BCG). While heart activity has been used for biometric authentication, sensing it through hand-based ballistocardiography (Hand-BCG) using standard sensors found on commodity mobile phones is an uncharted territory. Using a combination of in-depth qualitative analysis and large-scale quantitative analysis involving over 100 volunteers, we paint a detailed picture of opportunities and challenges. Authentication based on Hand-BCG is shown to be feasible but the signal is weak, uniquely prone to motion artifacts and does not land itself to the common approach of alignment-based authentication. HoldPass addresses these challenges by introducing a novel alignment-free authentication scheme that builds on asynchronous signal slicing and a data-driven algorithm for identifying a reduced set of features for characterizing a user. We implement HoldPass and evaluate it using a multi-modal approach: a large-case study involving 112 volunteers and targeted studies with a smaller set of volunteers over a period of several months. The data shows that HoldPass provides an authentication accuracy and user experience on par with or better than state-of-the-art systems with stronger requirements on hardware and/or user participation.

Introduction. The increased intensity of noise and vibration of railway traffic may become not only an urgent problem in the field of occupational safety, but also a serious environmental problem in the near future due to the constant need to increase the weight of freight trains, the speed of passenger trains and the capacity of railway lines. Recently, a lot has been done to minimize the negative effects of noise and vibration in railway transport. However, the problem of exceeding the indicators of vibration noise factors remains relevant. Reducing the harmful effects helps to improve the working conditions of train crew employees and improve the comfortable conditions of transport passengers. As a rule, the main focus of the analysis is on the external impact of vibroacoustic factors on residential areas and less attention is paid to the impact on rolling stock. However, these studies do not provide a complete picture of how noise and vibration actually affect the train in motion. The aim of the study was to obtain the result of an analysis of the impact of vibroacoustic factors on train crew workers and to propose a method of comprehensive protection based on the use of vibration damping materials.Materials and Methods. In the course of the work, regulatory documents were studied, a comprehensive analysis of relevant information on this topic was carried out, and methods for calculating vibration and vibration acceleration were used. The values of the sound pressure levels were obtained using a SPM-101 sound level meter. The object of the study was a carriage of the "reserved seat" type in the process of movement. As part of the research plan, sound pressure was measured at selected sites and a class of working conditions was determined.Results. The result of the analysis of the impact of vibroacoustic factors on train crew workers indicated the need to strengthen comprehensive measures to protect them. The obtained calculation of the vibration force became the basis of the method proposed by the authors to minimize the harmful effects of vibroacoustic factors, which was based on the use of vibration and sound insulation materials suitable for the necessary acoustic parameters in the construction of the car. In particular, it was proposed to cover the floor of the car with dense rubber and the ceiling of the car with an inorganic fiber material for sound insulation. The work also provides an economic assessment of the effectiveness of measures to minimize harmful vibration noise effects.Discussion and Conclusion. The proposed methods for minimizing noise and vibration impacts can help reduce the level of sound pressure and vibration indicators to standard values, which will significantly reduce the negative impact of vibroacoustic factors on train crew workers and railway passengers. The considered complex for minimizing vibration and noise includes a set of methods in which affordable materials based on recycled substances have found application.

This article deals with the challenge of travel as a category of the philosophy of transport in the unity of its ontological, epistemological, social and existential characteristics. Travel has its own ontology: this is a kind of beingness, defined as being-on-the-move. A trip becomes a travel through the reflection of an individual going on the trip. Travel has epistemological potential, it activates the cognitive activity of a person, creates new meanings and value paradigms. Travel is a social value as a means of transforming habitual social roles, destroying stereotypes, educating the ability to dialogue and tolerance towards the Otherness. The travel is not only a cross border process, but rather a transcultural one. The purpose, meaning, and result of a travel may be not just the change of a cultural picture, but of the entire cultural paradigm. Railways, being a purely technical phenomenon, have a well-known metaphysics which determines the existential transformations of the travelers. A railway line going beyond the horizon symbolizes a kind of existential infinity, limitlessness and vagueness. A travel is a kind of act of «communion» to this infiniteness, creates a sense of timelessness, while at the same time maintaining a sense of finitude, a blind end. The railway is a metaphor for a life’s journey, which has original and destination stations, and the train is an allegory of moving along it. A railway station is a metaphysical point of return/no return, separating life, people and actions. The railway and the travelling along it link together the beginning and the end, finitude and infiniteness, certainty and uncertainty, motion and immobility.

Testo completoAbstract (sommario):
This paper presents a method for determining the profile of the gear teeth on a variable radius wheel characterized by a constant pressure angle. The method can generate special gears using numerically controlled milling machines. As will be shown, the method, applied to a constant radius gear, generates an involute profile. The method is based on the integration of a differential equation describing the mesh between gears of variable radius, where the mesh point position is computed during rotation starting from the point, freely selected, where the tooth crosses the pitch line. The individual point is subsequently rotated in the opposite direction by an angle equal to the angle of rotation from the initial pitch line point, thereby generating the tooth profile. The method, applied to a wheel of variable radius, defined analytically or numerically, can compute teeth profiles on pairs of pitch lines of any shape. In particular, the motion of a slotted rotating link mechanism has been reproduced, but for the sign. Teeth profiles of other variable radius wheels have also been obtained. The results are more than satisfactory and are presented below. A numerically controlled milling machine has been programmed to actually build the antirotating slotted link equivalent gear. The present method, however, has much broader application, such as assigning the speed law to consequentially determine the gear form, as can be done with cams. Furthermore, a special planetary gear train makes it also possible to obtain reciprocating motion driven solely by gears. This has been built and its picture and scheme are presented in the paper. However, due to the low efficiency of the said mechanism, the best way to utilize this new technology seems to be to couple a crank and a rod to the pair of variable radius gears, as has been done at Hanover University. Some possible applications are presented. The special feature of these gears is the programmability of the shape of the pitch lines during the design phase, and thus of the velocity and acceleration profiles. In this way velocity profiles that could formerly only be obtained electro-pneumatically can be produced from purely mechanical components, with the added advantage of being able to control the level of inertia forces during the design phase.

Abstract As The Homeless Became An Established feature of American society in the early twentieth century, the image of this outcast group underwent a dramatic transformation. In middle-class literature and periodicals the view of the tramp as a dangerous, criminal agitator all but disappeared. No single stereotype replaced it; rather there emerged a number of overlapping—and frequently competing— images. Aspects of the traditional view that were not discarded were sometimes transformed in a way that would have astounded the moralists of the 1870s. What was once regarded as a defect in the moral sensibilities of the vagabond—such as his irresponsible desire to avoid work—sometimes became little more than a quaint idiosyncracy, if not actually a trait to be admired. The figure of the tramp also was significant in vaudeville, popular music, and early motion pictures. Reflecting the concerns and sentiments of a working- class or mixed-class audience, these popular entertainment forms often employed the symbol of the homeless man to criticize the in- equities of the new industrial order.
