Effective Mechanisms of Multiple LED Photographic Curing

Multiple LED Photographic Curing (MPC) has proven capable of drawing cross sections of three-dimensional objects like printing a sheet of paper. Using raster scanning, however, simultaneously exposing a photopolymer with 1,024 beams of light involves various unknown issues. The aim of this research work was to examine the formation of individual strings and the connecting mechanisms between strings and layers. At light power ranging from 19.0 to 30.3flW and at various scan speeds, string formation perpendicular to scan direction differs greatly from that in scan direction. Curing of plane layers happens by curing strings side-by-side with a constant spacing of 62.5flm.Mechanical Engineerin

Soft Turbulence in Bénard Convection Towards Intelligent Virtual Agents

This paper is concerned with logic dominant approach to intelligent virtual agents. It is found that the super complex systems can be only explored by syntheses together with intuition and/or imagination. This is not because we have limited tools to solve the super complex systems, but this approach is essential to solve such problems   &nbsp

Information Dynamic Analyses on American Football

This paper is concerned with the information dynamic analyses on American football games: One is the game in Eastern University American Football League, National Defense Academy vs. Chiba University, and the other is the Rice Bowl (Japan Championship)2020 Final, Fujitsu vs. Kansai University.  The former game is so called one-sided one, for National Defense Academy keeps the advantageous position against Chiba University throughout the game except at the normalized time η=0.25.  In the range that the normalized time η is greater than the value of 0.75, the model curve of ξ =η7 shows good agreement with game data.   It is found that the game point is at the normalized time η 0.9, where the game outcome becomes definitive and is the cross point between the certainty of game outcome ξ and the uncertainty of game outcome ς. The latter game modelled by ξ=η1.5 is typical one-sided one, and the game point is at the normalized time η0.62.  The two characteristic points in American football become evident through the present work, viz. (a)rules are rational and well organized, though sometimes they are too complicated, and (b)anyone can easily participate in the game not only as player, but supervisor, coach, cheer girl or member of cheering party, and/or supporter.  

Information Dynamics Towards Serious Game

This paper is concerned with information dynamics towards serious game. This study demonstrates that the proposed methodology can provide useful information to analyze game and to predict the outcome, respectively, in terms of soccer and girl’ height based on information dynamic model.  A plausible prediction method for human height has been proposed by incorporating the information dynamic model. Girl’s height at 10 years old is predicted until 25 years old, by knowing her height growth rate at starting year.   It may be considered that this is a sort of breakthrough on game research: The information dynamic model has been mainly used to do post hoc analyses for the finished games, but it has also potential to predict the game outcome before the start, if initial conditions are given. As a popular and simple game, soccer has been analyzed and presented how advantage and certainty of game outcome depend on the time.   In the data analyses, as evaluation function scores in addition to goal, shoot, corner kick, or penalty kick are adopted to conduct refined analyses. The game patterns have been categorized into see-saw, one-sided, balanced and others, and is defined quantitatively, to promote understanding game.        &nbsp

Exact Solution of Grid Produced Turbulence; New Approach

A new approach to the kinetic theory of grid produced turbulence in the final period of decay has been proposed. The governing equations are the two-point velocity correlation equations in which the triple-point correlations are neglected as the closure assumption, and the pressure-velocity correlations are discarded by considering the homogeneous turbulence. Without recourse to the isotropic conditions, these equations are found to be separable into a pair of Oseen type equations.   As a result, the double velocity correlations are solved exactly as an initial value problem. It has been shown that the decay law for the turbulent energy in the final period becomes in the form,                   ≺(∆u)2/U2 = 3 [1 + 8(xx0/M)/(2Re)]-5/2, where  ≺(∆u)2≻/U2 is the normalized turbulent energy, U the main flow velocity, x the coordinate in the main flow direction, M the grid mesh size, x0 the point at which the initial condition is given,  the constant determined by each the initial condition, and Re the Reynolds number based on U and M. The present theory shows reasonable agreement with the experiment

Capillary Waves Generated by a Rock in a Stream

This paper is concerned with capillary waves generated by a rock, or fishing line in a stream.  It is found mathematicaly that the angle between the capillary wave envelope and the direction of a point source is dependent of the velocity, surface tension, and density of the fluid: This angle increases with increasing the surface tension, but decreases with increasing the square of velocity and the density of fluid.   These theoretical outcomes are consistent with the detailed behaviors of capillary waves observed in the natural running streams. To enhance the mathematical analyses on capillary waves generated by a fishing line with constant speed, the relevant non-dimensional parameters 1=Ut/r and 2=r3 /(t2 ) have derived based on the Buckingham -Theorem, where U the relative stream velocity, t the time, r the distance from the point source of wave generation,  the surface tension, and  the density of the fluid.  It has been confirmed by the present proposed approach that the angle between the gravity wave envelope and the direction of a duck or ship moving on the calm water surface is constant of 19.28 which agrees with the result obtained by “Thomson, W., 1887 On ship waves, Institution of Mechanical Engineers, Minutes of Proceedings, 409-434” and “Adam, J.A., 2003 Mathematics in nature: modelling patterns in the natural world, Princeton University Press, Princeton, 161-172”

Information Dynamics in Baseball

This study is concerned with the information dynamics in baseball. This simulates and models the history of professional baseball game Carp vs. Giants in Japan Central League , and provides us useful strategy and/or tactic for coping with the future games, and method for predicting the game outcomes. The game, Carp vs. Giants is quite a unique one, for Giants keeps the advantage against Carp over 90% of the total game length, but is reversed by Carp just before the end. Thus, this game should be called as one-sided game by Giants, though Carp becomes the winner.   It is found that a model curve for height, which initial slope angle coincides with that of data curve, provides the minimum current value of height depending on the time. Usefulness of the information dynamic model for predicting game outcome has been demonstrated: It is predicted in such a way that the author’s granddaughter in 10 years old on August 13, 2018 will increase her height in 10 years from 127.5 cm to 167.6 cm

Three Wakas at Evening in The Autumn with Reference to Tea Ceremony

This letter is concerned with the three Wakas at evening in the autumn, which may be most popular and are compiled in Shin-Kokinwakashu.  It is realized that Waka is a short literal sculpture based on pointillism, and filling enormous amount of contents regarding emotion and/or scenery.  The first common characteristic point of these three Wakas is to be paused at the end of the third passage, respectively.  The second characteristic point is that the fifth passage is a common phrase.   They describe lonely scenery at the mountain, swamp, and seashore, respectively, at evening in the autumn without using any subjective literal expression.  It is, therefore, suggested that they become the symbol of a simple tea ceremony, and provide the original idea to establish the standard rules. Japanese people have been continued to be influenced by the rules in their daily lives for long time

Japan Judo Championship 2019

This paper is concerned with the case studies on Final and Semi-final in All Japan Judo Championship 2019, and is analyzing the relevant data in terms of the information dynamic model.  The Final is a typical balanced game, which is finished by the Golden Score, while the Semi-final is classified as one-sided game. In the Semi-final, it has been shown that the winner gets the safety lead against the loser at the normalized time η0.8, which means that outcome of this match becomes definite at the stage, 80% of the total game length. It is inferred that in the All Japan Judo Championship, the sudden death of both players will occur, but drawn game cannot be expected anymore, as far as the current refereeing rules are sustained. It is realized that the present approach is promising to predict the history and outcome of any game before it starts, so that it is useful for preparing the tactics or strategy for future games
