Abstract:

Abstract Cupric hydroxide formulated as Spin Out™ (7% Cu(OH)2 in a latex carrier, w/w) was used to prevent rooting-out of Taxus × media Rehd. ‘Densiformis’ root balls into surrounding mulch or soil during storage over a four-month period. Treatments included: painting the bottom of the root ball with Spin Out™, setting the root ball on Spin Out™-treated burlap or on untreated burlap, and rewrapping the root ball with Spin Out™-treated burlap or burlapping using Spin Out™-treated burlap before mulching. All treatments provided some control of rooting-out after 12 to 16 weeks storage. The most effective treatments were 1) in unmulched situations, setting the root ball on Spin Out™-treated burlap (92% reduction in root count after 16 weeks), and 2) in mulched situations, either rewrapping or burlapping with Spin Out™-treated burlap (90% and 86% reduction in root count, respectively, after 16 weeks). Using Spin Out™-treated burlap to prevent rooting-out during storage can reduce the incidence of re-balling and root removal prior to shipping and planting stored B&B nursery stock.

Abstract:

Ceramic balls have become an important component in advanced bearings, and the sphericity of balls is a key qualification focused in lapping process. An investigation on the effect of dynamic behavior of ball support system on the performance of ball lapping in rotated dual-plates lapping method is carried out. Sinusoidal waveform in terms of Fourier analysis is employed to express the shape error of the ball surface, and a dynamic model for support is setup. It is found with numerical calculation that the variation of lapping load lags behind the variation of the shape error for the damping of support. A lower natural frequency of the support system, higher spin speed of balls and a larger value of spin angle in RDP lapping are better to rectify the shape error of balls and reduce the lagged effect. It is concluded that dynamics of lapping system must be taken into consideration in order to understand comprehensively the spherical surface generation mechanism.

Abstract:

Dual Rotated Plates (DRP) eccentric lapping mode is developed on the base of traditional eccentric lapping mode for precise balls. Spin angle is an important target of expressing ball rotation in the lapping process. Whether lapping track can uniformly cover the ball surface or not is directly determined by the variation of the spin angle. Applying virtual prototype technology and ADAMS (Automatic Dynamic Analysis of Mechanical Systems) to simulate the ceramic ball lapping track in DRP eccentric lapping mode. And these results are compared to traditional one. At the same condition, the DRP eccentric lapping mode owns better lapping uniformity than traditional one and it is easy to apply to science for the simplicity of structure and control. The result may offer theoretical basis for high-precision ceramic balls machining.

Abstract:

Basketball players are taught to release the ball with a backward spin. This causes a lift due to the Magnus effect. Added to this there is a drag on the ball which always acts opposite to the direction of motion. In this paper, the trajectory of a basketball considering the lift and drag is calculated using numerical methods and also the force required to shoot the ball with different initial conditions from a distance of 25 feet away from a basket which is at a height of 10 feet is analyzed. A differential equation of motion of the ball in air is framed which accounts for all the forces on the ball. It is solved by discretizing the equation and solved using a C++ code. The trajectory of the balls with different initial conditions is plotted and it is found that as the spin on the ball increases, the effort required to shoot decreases.

Abstract:

This study discuss the distribution of the flows when the forced convection impacted on the spin and the static in table tennis; the research method is using the thermal flow in the experiment which the thermal flow will reflect according to the imaging principle when it passes through the spin sphere; this can be used to simulate the flows of balls in static condition and backspin ball in high-speed and low-speed rotation; the air flow passes through the spin sphere and generates the ball pressure which forms the quality variation of the spheres in table tennis competition; the results showed that it has a lower drag force, low fluid momentum and lower rectilinear speed when the sphere is in static condition , low Reynolds number; on the contrary, it has a higher drag force and increasing rectilinear speed of flows when the Reynolds number is high. When the ball is in backspin condition, the flows are symmetrical presented, and then the flows are gradually distributed, asymmetrical presented and are upward. The higher the Reynolds number is, the smaller the wake region is due to that the forced convection effect increased; the smaller the Reynolds number is, the ball will have more significant spin kinetic energy increasing rate when the spin speeds up.

Abstract:

AbstractIdentifying the trajectory and spin of the ball with speed and accuracy is critical for good performance in table tennis. The aim of this study was to analyze the ability of table tennis players presenting different levels of training/experience to identify the magnitude of the ball spin from the sound produced when the racket hit the ball. Four types of “forehand” contact sounds were collected in the laboratory, defined as: Fast Spin (spinning ball forward at 140 r/s); Medium Spin (105 r/s); Slow Spin (84 r/s); and Flat Hit (less than 60 r/s). Thirty-four table tennis players of both sexes (24 men and 10 women) aged 18-40 years listened to the sounds and tried to identify the magnitude of the ball spin. The results revealed that in 50.9% of the cases the table tennis players were able to identify the ball spin and the observed number of correct answers (10.2) was significantly higher (χ2 = 270.4, p <0.05) than the number of correct answers that could occur by chance. On the other hand, the results did not show any relationship between the level of training/experience and auditory perception of the ball spin. This indicates that auditory information contributes to identification of the magnitude of the ball spin, however, it also reveals that, in table tennis, the level of training does not interfere with the auditory perception of the ball spin.

Abstract:

Oblique impacts between a ball and surface are a key part of many sports. Previous work has shown that a ball can slide, over-spin or roll at the end of an impact, depending on impact conditions. Inbound spin ratio was analysed to determine if it could be used to identify what is likely to happen at the end of impact for all sports regardless of surface, ball type, impact velocity, angle and spin. A predictive model, in the form of a finite element model, of a tennis ball was validated against experimental data for oblique impacts with inbound spin ratios in the range of –1 to 1. Spin ratio is defined as the product of the ball’s angular velocity and radius divided by the centre of mass velocity tangential to the surface. The finite element model was then used to determine the effect of impact conditions and ball parameters on outbound spin ratio. The study showed that for constant inbound spin ratio, outbound spin ratio was dependent on inbound velocity and angle. For constant inbound velocity and angle, decreasing the mass and increasing the stiffness of the ball through a change in material properties resulted in an increase in the maximum outbound spin ratio. Inbound spin ratio can be used to predict how a ball will rebound from a surface; however, inbound velocity and angle must be constant. Spin ratio can therefore be used to compare the impact characteristics for different ball and surface scenarios.

Abstract:

The following article considers lift and drag measurements of solid sports balls propelled through still air in a laboratory setting. The balls traveled at speeds ranging from 26 to 134 m/s with spin rates up to 3900 r/min. Light gates measured the speed and location of the balls at two locations from which lift and drag values were determined. Ball roughness varied from polished to rough surface protrusions, that is, seams as high as 1.5 mm. Lift and drag were observed to depend on speed, spin rate, surface roughness, and seam orientation. A drag crisis was observed on smooth balls as well as non-rotating seamed balls with seam heights less than 0.9 mm. The drag coefficient of approximately 0.42 was nearly constant with speed for spinning seamed balls with seam height greater than 0.9 mm. The still air drag coefficient of smooth balls was comparable to wind tunnel drag at low speeds ( Re < 2 × 105) and higher than wind tunnel results at high speeds ( Re > 2 × 105). The lift and drag coefficients of spinning balls increased with increasing spin rate. The lift coefficient of baseballs was not sensitive to ball orientation or seam height.

Abstract:

O tênis de mesa é um dos esportes de raquete mais rápidos do mundo, exigindo muito pouco tempo para planejar e executar seus movimentos. Neste sentido, detectar a quantidade de rotação da bola, velocidade e direção torna-se fundamental para produzir respostas motoras eficientes. Entretanto, existem algumas questões que ainda não foram exploradas como o quanto a disponibilidade das informações auditiva e visual interfere na acurácia da percepção da rotação da bola e no tempo necessário para perceber estas rotações. O propósito do presente estudo foi analisar a influência da informação auditiva e visual na percepção da rotação da bola e no desempenho no tênis de mesa. Os atletas profissionais foram submetidos a dois estudos: o primeiro destinado a verificar a contribuição da informação auditiva e visual na percepção da rotação da bola e no tempo necessário para essa percepção. O segundo, proposto para avaliar a influência da informação auditiva no desempenho da tarefa de contra-ataque no tênis de mesa. Participaram do estudo 22 mesatenistas de alto rendimento de ambos os sexos (21 homens e 1 mulher) com média de idade de 22,55 ± 6,15. O teste de percepção de rotação (estudo 1) analisou o número de acertos e o tempo de reação por meio de uma rotina desenvolvida no software Matlab (Apêndice D). Os atletas visualizavam a tela de um computador e respondiam em um teclado o mais rápido possível. Os atletas analisaram um movimento de forehand nas intensidades de rotação: muita rotação (bola girando a aproximadamente 140 r/s); média (bola girando a aproximadamente 105 r/s); pouca rotação (bola girando a aproximadamente 84 r/s); batida chapada (bola girando a aproximadamente 70 r/s), nas seguintes condições: a) informação auditiva; b) informação visual; c) informação auditiva e visual. Os atletas analisaram 20 bolas para cada condição sendo cinco de cada tipo de efeito. Para o teste de desempenho (estudo 2) o atleta teve que responder adequadamente com o movimento de contra-ataque de forehand em um alvo previamente marcado na mesa. Foram golpeadas 80 bolas nas mesmas intensidades de rotação mencionadas acima. Os atletas foram avaliados em duas condições: com informação auditiva e sem informação auditiva. Os resultados do estudo 1 revelaram que mesatenistas foram capazes de perceber a magnitude de rotação da bola nas três condições. O percentual de acertos foi de 77,5%, 91,14% e 96,36% para as condições de informação auditiva, visual e combinadas, respectivamente. Quanto ao tempo de reação, os resultados revelaram que na condição somente informação auditiva (2,32 ± 0,41 s) os atletas demoraram mais tempo para responder do que em relação a condição somente informação visual (2,07 ± 0,36 s), já na condição informação auditiva e visual (1,85 ± 0,35 s) os atletas se mostraram mais rápidos ainda concordando com as informações número de acertos obtidas neste estudo. Para o estudo 2 os resultados revelaram que quando os atletas contra-atacaram na condição informação auditiva, o número de acertos foi de 37,69 ± 5,43 enquanto, quando a audição dos atletas foi privada a média de acertos foi 33,15 ± 6,84. Os resultados apontaram que mesatenistas foram capazes de utilizar as informações auditiva e visual para perceber a magnitude da rotação da bola no golpe forehand, porém, no estudo 1 quando as informações foram combinadas o número de acertos aumentou 5,22% e o tempo de reação diminuiu 0,22 s. No estudo 2 Quando a informação auditiva foi privada houve uma diminuição na média do número de acertos de 4,54.<br>Table tennis is one of the fastest racket sports in the world, requiring very little time to plan and execute your moves. In this sense, detecting a quantity of ball spin, velocity and direction becomes fundamental to produce efficient motor responses. However, there are some questions that have not yet been explored for example how much the availability of auditory and visual information interferes with the accuracy of the perception of the rotation of the ball and the time needed to perceive these rotations. The purpose of the present study is to analyze the influence of auditory and visual information on the perception of ball rotation and performance in table tennis. The volunteers were submitted to two studies: the first one to verify the contribution of the auditory and visual information in the perception of the rotation of the ball and in the time necessary for this perception. The second, proposed to evaluate the influence of auditory information on the performance of the counter-attack task in table tennis. Twenty-two high-level table tennis players men and women (21 men and 1 woman) with a mean age of 22.55 ± 6.15 participated in the study. The rotation perception test (study 1) analyzed the number of hits and the reaction time through a routine developed in Matlab software. The athletes visualized the screen of a computer and answered in a keyboard as soon as possible. The athletes analyzed a forehand movement in the rotation intensities: fast spin (spinning ball foward at 140 r/s); medium spin (105 r/s); slow spin (84 r/s); flat hit (70 r/s), under the following conditions: a) auditory information; b) visual information; c) auditory and visual information. The athletes analyzed 20 balls for each condition, five of each type of rotation. For the performance test (study 2) the athlete had to respond adequately with the forehand counterattack movement on a previously marked target at the table. 80 balls were struck at the same intensities of rotation mentioned above. The athletes were evaluated in two conditions: with auditory information and without auditory information. The results of the study 1 revealed that table tennis players were able to perceive the magnitude of rotation of the ball in the three conditions. The percentage of correct answers was 77.5%, 91.14% and 96.36% for auditory, visual and combined information conditions, respectively. Regarding the reaction time, the results revealed that in the condition only auditory information (2.32 ± 0.41 s) the athletes took more time to respond, since in the condition only visual information (2.07 ± 0.36 s) delayed a little less and in the condition auditory and visual information (1.85 ± 0.35 s) the athletes showed themselves to be faster still agreeing with the information number of hits obtained in this study. For the study 2 the results revealed that when the athletes counterattacked in the auditory information condition, the number of hits was 37.69 ± 5.43, whereas when the hearing of the athletes was private the average hit was 33.15 ± 6.84. The results indicated that table tennis players were able to use auditory and visual information to realize the magnitude of the ball rotation in the forehand blow, however, in study 1 when the informations were combined the number of right answered increased 5.22% and the reaction time decreased by 0.22 s. In study 2 When the auditory information was depriving, there was a decrease in the average number of hits 4.54.

Abstract:

O presente trabalho propõe uma nova perspectiva ao debate sobre bailes e danças na Espanha do século XVII. Diante das variadas classificações que a bibliografia intenta formular, observa-se uma preocupação em distinguir os dois conceitos. Nesse sentido, os bailes são colocados como descompostos em seus gestos e exercitados por subalternos, enquanto as danças apresentam compostura e são realizadas pelas elites. Entretanto, há divergências entre os autores e contradições em uma mesma classificação, as quais se manifestam de acordo com as fontes utilizadas. Ao analisar as fontes, nota-se que suas formulações sobre tais práticas corporais são construídas a partir de uma moral gestual e por um ideal cortesão. Logo, trata-se de representações elaboradas pela articulação daqueles valores e ideais, e não de uma realidade. Partindo dessas constatações, coloca-se a hipótese de que a maior repressão e depreciação aos bailes, ou a tal conceito, seria uma forma mais eficaz da Igreja controlar e reformar tais práticas, pois os bailes eram realizados pelas distintas ordens sociais e em diversos ambientes, como na própria igreja, além de terem sido os mais representados nos palcos durante o processo da teatralização.<br>This dissertation thesis proposes to develop a new perspective to the debate on balls and dances in seventeenth-century Spain. Given the various attempts to classify, there is in the up-to-date bibliography a need to distinguish both concepts from each other. Thus, balls are said to be decomposed in its gestures and performed by lower social classes, while dances preserve their composure and is performed by the elites. However, there is a disagreement between authors that contradicts the same classification, as can be seen in different sources used by them. By analyzing the sources, it´s evident that its foundation lies on bodily practices built under a moral gesture and an ideal courtier. Thus, these are representations wrought out from values and ideals, not from a reality. Based on these findings, our hypothesis is that the greater repression and depreciation of balls or similar concepts would be a more effective way that the Church used to control and reform these practices, for the balls were performed by different social orders, to an extent, the church in itself, besides being the first mostly depicted on stage during the process of dramatization.

Abstract:

La première partie des travaux réalisés a été dédiée à l' élaboration de composés LaFe13-xSix (1,3 ¡U x ¡U 2,2) par broyage à haute énergie. Il a fallu déterminer les conditions de synthèse et de recuit optimales pour l'obtention d'échantillons monophasés. Leur homogénéité a été analysée par diffraction des rayons X et microsonde électronique. Les résultats ont montré qu'une microstructure plus fine favorise la formation de la phase désirée : un recuit de 30 min (au lieu de 30 jours pour les massifs) à 1373K suffit à l'obtention d'un composé quasi-monophasé. D'après les mesures magnétiques effectuées, les composés synthétisés par broyage mécanique ont des proprié¦tés magnétiques et magnétocaloriques similaires aux massifs. Ils présentent une transition métamagnétique des électrons itinérants induite par le champ ou la température. Leur température de Curie augmente avec le Si, variant de 200K à 235K pour x = 1,4 à 2,0 alors que leur variation d'entropie magnétique diminue de 20 J/kg K à 4 J/kg K sous une variation de champ de 0-2 T. La deuxième partie de l'étude a consisté à améliorer les propriétés magnétocaloriques des intermétalliques par l'insertion d'atomes interstitiels (H, C). Les mesures magnétiques ont montré une nette augmentation de la température de transition (jusqu'à Tamb.) par effet magnétovolumique tout en conservant un effet magnétocalorique important. Les analyses par diffraction des neutrons en température effectuées sur les composés deutérés ont permis de suivre l'évolution des données cristallographiques et des moments magnétiques par Fe. Il ressort de cette étude que ces composés présentent un grand intérêt dans la recherche de futurs matériaux magnétocaloriques pour la réfrigération magnétique à température ambiante. Dans le cadre de l'exploration de nouveaux systèmes, les propriétés magnétocaloriques des composés Y1-xRxFe2D4,2 (R = Er, Tb) ont également été étudiés en couplant les études magnétiques avec des mesures de diffraction des neutrons

Abstract:

This chapter begins with a definition of spin Hall effects, which are a group of phenomena that result from spin–orbit interaction. These phenomena link orbital motion to spin direction and act as a spin-dependent magnetic field. In its simplest form, an electrical current gives rise to a transverse spin current that induces spin accumulation at the boundaries of the sample, the direction of the spins being opposite at opposing boundaries. It can be intuitively understood by analogy with the Magnus effect, where a spinning ball in a fluid deviates from its straight path in a direction that depends on the sense of rotation. spin Hall effects can be associated with a variety of spin-orbit mechanisms, which can have intrinsic or extrinsic origin, and depend on the sample geometry, impurity band structure, and carrier density but do not require a magnetic field or any kind of magnetic order to occur.

Abstract:

My late wife Marina and I joined the Anglo Spanish Society over forty years ago, when Sir Peter Allen was Chairman. He had been Chief Executive of ICI and was married to the elegant and charming Consuelo Allen, whose family owned the glamorous Embassy Café in Madrid. I became a member of the Council. In those days our Society’s main event was a ball held mostly at the Grosvenor House Grand Ball Room in Park Lane. It was a major event in the social calendar attracting between six hundred and a thousand punters. Often Royalty were present. I can remember Prince Edward attending with Princess Elena of Spain and on another occasion Princess Alexandra and her husband, Sir Angus Ogilvy. When the ball took place at Syon House, Prince Charles and Lady Diana graced the occasion....

Abstract:

A model of impact of a tennis ball with a flat surface is developed based on a planar, two-mass, linear, four degree of freedom vibration system idealization. The impact is assumed to be incident on a flat surface with friction. The incident parameters of the ball include the centre of mass translational velocity, angle of impact with the surface and the incident angular spin of the ball. The linear, piecemeal vibration model predicts the corresponding rebound parameters of the tennis ball. The model also predicts the duration of contact of the tennis ball with the flat surface, the transition of motion of the tennis ball during contact with the ground from sliding to rolling contact, and the resulting contact forces developed between the tennis ball and the flat surface. The model is computationally efficient because the governing differential equations of motion are linear and their standard solutions can be easily implemented on a personal computer. Predictions of the rebound parameters from the model are compared with experimental findings on tennis balls which are incident on a flat surface with various angles, velocities and angular spins (zero spin, topspin and backspin). For selected parameters of the two-mass model, the comparisons show excellent agreement between the model and the measurements.
