Мужская субкультура и свойственные ей мировоззренческие установки имели особенно большое значение в жизни традиционного общества. В трансформированном виде мужская система ценностей, образ мышления и форма поведения, свойственные традиционному обществу, продолжают существовать и в современном обществе. Этим обусловлена актуальность всестороннего изучения мужских субкультур традиционного общества. Комплексное исследование традиционных мужских субкультур важно для осмысления скрытых тенденций эволюции и объективного восприятия принципов развития современного общества. В значительной степени мужская субкультура проявляется в бытовавших в мужской среде состязаниях, играх и забавах. В настоящей работе проанализированы традиционные осетинские мужские игры и состязания, характерными элементами которых были быстрое передвижение, бег, лазанье, прыжки. Научная новизна определяется тем, что данная работа является первым комплексным исследованием подвижных мужских игр на осетинском материале. Источником при разработке поставленной проблемы послужили этнографический материал и фольклорные тексты. В данной статье выявлены и рассмотрены наиболее распространенные среди осетинского мужского населения состязания и игры, предполагавшие быстрое передвижение; отмечены стереотипы мужского поведения во время участия в исследуемых состязаниях и играх; проанализированы видоизменения, встречающиеся в некоторых из мужских игр и состязаний; выявлено влияние подвижных игр и состязаний на укрепление внутригрупповой солидарности в мужских коллективах в традиционном обществе; определено военно-прикладное значение некоторых из рассмотренных игр и состязаний; установлено существование корреляционной зависимости между религиозно-магическими обрядами и традиционными мужскими играми в традиционном осетинском обществе; определено воздействие трансформаций в общественном сознании на мужские состязания и стереотипы мужского игрового поведения. The men’s subculture and its inherent ideological attitudes were especially important in the life of the traditional society. In a transformed form, the men’s value system, way of thinking and form of behavior inherent in traditional society continue to exist in the modern society. This explains the relevance of a comprehensive study of men’s subcultures of the traditional society. A comprehensive study of traditional men’s subcultures is important for understanding the hidden trends of evolution and the objective perception of the principles of development of the modern society. To a large extent, the men’s subculture manifests itself in the competitions, games and amusements that existed in the men’s environment. This work analyzes Ossetian traditional men's games and competitions, a characteristic element of which was fast movement, running, climbing, jumping. The scientific novelty is determined by the fact that this work is the first comprehensive study of active men’s games based on the Ossetian material. Ethnographic material, folklore texts served as a source in the development of the problem posed. This article identifies and examines the most common competitions and games among the Ossetian men’s population, which involved fast movement; noted stereotypes of men’s behavior during participation in the reviewed competitions and games; analyzed the modifications found in some of the men's games and competitions; the influence of active games and competitions on the strengthening the intragroup solidarity in men's teams in the traditional society was revealed; the military-applied significance of some of the games and competitions considered is determined; the existence of a correlation between religious and magical rituals and traditional men’s games in the traditional Ossetian society has been established; the impact of transformations in public consciousness on men’s competitions and stereotypes of men’s play behavior is determined.

Human–computer interaction systems have been developed in large numbers and quickly applied to sports. Badminton is the best sport for applying robotics because it requires quick recognition and fast movement. For the development of badminton recognition and tracking systems, it is important to accurately identify badminton, venues, and opponents. In this paper, we designed and developed a badminton recognition and tracking system using two 2 000 000-pixel high-speed cameras. The badminton tracking system has a transmission speed of 250[Formula: see text]fps and the maximum speed of the badminton resonator is 300[Formula: see text]km/h. The system uses the camera link interface Camera Link to capture images of high-speed cameras and process all captured images in real time using different regions of interest settings. In order to improve accuracy, we propose a new method for judging the center point of badminton. We have proposed a detector that detects the four corner points of the field by using the contour information of the badminton court when the approximate position of the badminton court is known. We set the sensing area according to the approximate position of the badminton court and use the histogram in the sensing area to select the point closest to the contour. Specify the intersection of the line as the corner point of the badminton court. The proposed angle detector has a high detection rate. It is more than 10 times more accurate than traditional detectors. The moving badminton is detected by an elliptical detector. We propose a method to find the center of the correct ellipse from the four candidates by selecting the four candidate contours of the ellipse. Compared to conventional circular detectors and points on three-dimensional coordinates, the proposed elliptical detector reduces the error by about 3[Formula: see text]mm.

The work deals with the problem of using flat belts in internal transport systems. There are many modern solutions for such belts, but to use them in demanding logistics systems, it is necessary to analyze the basic problems associated with coupling in a belt transmission. Then fast movement and transport problems can be solved. All these parameters contribute to the new approach to the belt-pulley coupling model, which was proposed in this paper.

Cytoplasmic streaming with extremely high velocity (~70 μm s−1) occurs in cells of the characean algae (Chara). Because cytoplasmic streaming is caused by organelle-associated myosin XI sliding along actin filaments, it has been suggested that a myosin XI, which has a velocity of 70 μm s−1, the fastest myosin measured so far, exists in Chara cells. However, the previously cloned Chara corallina myosin XI (CcXI) moved actin filaments at a velocity of around 20 μm s−1, suggesting that an unknown myosin XI with a velocity of 70 μm −1 may be present in Chara. Recently, the genome sequence of Chara braunii has been published, revealing that this alga has four myosin XI genes. In the work reported in this paper, we cloned these four myosin XIs (CbXI-1, 2, 3, and 4) and measured their velocities. While the velocities of CbXI-3 and CbXI-4 were similar to that of CcXI, the velocities of CbXI-1 and CbXI-2 were estimated to be 73 and 66 μm s−1, respectively, suggesting that CbXI-1 and CbXI-2 are the main contributors to cytoplasmic streaming in Chara cells and showing that CbXI-1 is the fastest myosin yet found. We also report the first atomic structure (2.8 Å resolution) of myosin XI using X-ray crystallography. Based on this crystal structure and the recently published cryo-EM structure of acto-myosin XI at low resolution (4.3 Å), it appears that the actin-binding region contributes to the fast movement of Chara myosin XI. Mutation experiments of actin-binding surface loop 2 support this hypothesis.

A dynamic image has a distinct quantity of object movement from one to another. It can be any object such as a car, person, an object moving from one point X to another point Y. Image consists of a sense of movement. Applications of object tracking are biometrics tracking, AR uses, video surveillance, passage monitoring, vehicle navigation, etc. Challenges in tracking multifaceted objects are fast movement, geometric conversion, blurring, messy background, artifacts, etc. To resolve this problem by merge all small features with nearby texture features. Texture feature describes the plane space and configuration of an area. A mixture of color and texture feature improves the object details and to increase the strength of the object's illustration. In Existing methods such as binary pattern method all object features are removed, so it is difficult to predict the exact pixel movement. The proposed method of improved binary pattern is also tracking the small changes in the pixel difference in one frame to other. Compared with the existing algorithms, IBP method measures the spatial arrangement of local image texture which reduces the overall processing cost and improves the strength of objective image. To track the similarities and difference of the object in each and every frame efficiently and effectively Improved Local Binary Pattern tracking algorithm was proposed. This proposed technique is an effective way to analysis complicated real time situations compared with other methods.

<p>The majority of Greenland’s outlet glaciers are Isbræ-type, with high driving stresses, steep surface slopes, flow through deep channels, and with a basal layer of temperate ice theorised to thicken towards the coastal margin. Understanding the formation processes and thermodynamic influence of this temperate ice is important as limited laboratory testing indicates temperate ice has a viscosity 5-10 times lower than cold ice with no liquid phase. Furthermore, limited field data suggests lower rates of deformation within basal temperate ice than in the cold ice directly overlying it, which is presently unexplained. Here, we present preliminary results from a 3D finite-element model of an idealised Isbrae-type glacier built with Elmer/Ice, incorporating water-content-dependent ice viscosity, basal melting, and a parameterization of basal crevassing, and use it to investigate the formation and thermodynamic behaviour of temperate ice in response to varying bedforms and model parameters. We find that the observed decrease in strain in temperate ice close to the glacier base can be explained by a high strain area close to the cold-temperate transition zone. We further compare our model results to temperate ice variability observed at Sermeq Kujalleq (Store Glacier) to determine key temperate ice parameters requiring further investigation. These results provide a more complete understanding of the heterogeneous ice deformation behind the fast movement of Greenland’s Isbræ-type glaciers and can therefore help to improve predictions of future glacier flow.</p>

AbstractChina’s temperate glaciers have a relatively warm and humid climate and hydrothermal conditions at low latitudes. Temperate glaciers, however, have larger ablation, higher ice temperatures, relatively fast movement speeds, and a significant sliding process at the bottom. As a result, these glaciers are more significantly affected by climate change. On the basis of topographic maps, aerial photography, and Landsat OLI images, and combined with existing research results, this paper systematically analyzed the temporal and spatial dynamic characteristics of typical temperate glaciers. The results are as follows: (1) From the 1950s to the 1970s, compared with other types of glaciers, temperate glaciers showed strong retreat and ablation trends in terms of area, length, speed, and mass balance. (2) The reduction rates of glacier areas of Kangri Garpo, Dagu Snow Mountain, Yulong Snow Mountain (YSM), and Meili Snow Mountain (MSM) in China’s temperate glacier areas all exceeded 38%, which was far above the national average of 18% from the 1950s to the 2010s. (3) The recent length retreat rates of Azha Glacier, Kangri Garpo, and Mingyong Glacier, MSM, Hailuogou Glacier (HG), Gongga Snow Mountain (GSM), and Baishui River Glacier No. 1 (BRGN1), YSM were above 22 m/a, which was faster than the retreat rates of other regions. (4) Consistent with glacier retreat, temperate glaciers also had a faster ice flow speed. The ice flow velocities of the BGN1, HG, Parlung River Glaciers No. 4 and 94, and Nyainqêntanglha were, respectively, 6.33–30.78 m/a, 41–205 m/a, 15.1–86.3 m/a, and 7.5–18.4 m/a, which was much faster than the velocity of other types of glaciers. (5) Mass loss of temperate glaciers was most dramatic during the observation period (1959–2015). The annual mass balance from eight typical temperate glaciers fluctuated between − 2.48 and 0.44 m w.e., and the annual average change rate of mass balance (− 0.037 m w.e./a) was much higher than that in China (− 0.015 m w.e./a, p < 0.0001) and globally (− 0.013 m w.e./a, p < 0.0001).

This lesson uses a fast movement from an Albinoni sonata to investigate various devices that are essential for bringing Baroque music to life. The main focus is on how to play a line of equal notes in an interesting way: three flexibilities are identified: rhythm, dynamics, and articulation, with special exercises devised to maximize the uses of each one. The question of sequences is explored in detail (there are eleven in the movement) along with the issue of adding (or not) slurs where the composer writes none.

The services of the Video on Demand (VoD) are currently based on the developments of the technology of the digital video and the network’s high speed. The files of the video are retrieved from many viewers according to the permission, which is given by VoD services. The remote VoD servers conduct this access. A server permits the user to choose videos anywhere/anytime in order to enjoy a unified control of the video playback. In this paper, a novel adaptive method is produced in order to deliver various facilities of the VoD to all mobile nodes that are moving within several networks. This process is performed via mobility modules within the produced method since it applies a seamless playback technique for retrieving the facilities of the VoD through environments of heterogeneous networks. The main components comprise two servers, which are named as the GMF and the LMF. The performance of the simulation is tested for checking clients’ movements through different networks with different sizes and speeds, which are buffered in the storage. It is found to be proven from the results that the handoff latency has various types of rapidity. The method applies smooth connections and delivers various facilities of the VoD. Meantime, the mobile device transfers through different networks. This implies that the system transports video segments easily without encountering any notable effects.In the experimental analysis for the Slow movements mobile node handoff latency (8 Km/hour or 4 m/s) ,the mobile device’s speed reaches 4m/s, the delay time ranges from 1 to 1.2 seconds in the proposed system, while the MobiVoD system ranges from 1.1 to 1.5. In the proposed technique reaches 1.1026 seconds forming the required time of a mobile device that is switching from a single network to its adjacent one. while the handoff termination average in the MobiVoD reaches 1.3098 seconds. Medium movement mobile node handoff latency (21 Km/ hour or 8 m/s) The average handoff time for the proposed system reaches 1.1057 seconds where this implies that this technique can seamlessly provide several segments of a video segments regardless of any encountered problems. while the average handoff time for the MobiVoD reaches 1.53006623 seconds. Furthermore, Fast movement mobile node handoff latency (390 Km/ hour or 20 m/s). The average time latency of the proposed technique reaches 1.0964 seconds, while the MobiVoD System reaches to 1.668225 seconds.
