3次元 CG は,実写写真のようなフォトリアルな画像を生 成するために発達してきた技術である.一方,2次元のセル アニメ調アニメーションの生成に用いられるトゥーンシェー ディングは,3次元 CG の中の一手法ではあるが,フォトリ アルな画像を生成するという本来の目的を軌道修正した事に より,セルアニメ的な画像生成に一定の効果を上げている. しかし,トゥーンシェーディングは,3次元 CG による元々 のシェーディングの目的とは異なる,ノンフォトな画像生成 を目的とするため,その生成結果の画像に様々な不都合を生 じる事がある.その中の1つの例が,光源によって生じる キャラクタの影や陰影の形状である.セルアニメーションの 画像は制作効率の事を考慮するために,常にシンプルな形状 の影や陰影を適応している.しかし,トゥーンシェーディン グによって生成される影や陰影は,モデルの形態によって は,必ずしもシンプルな形状にはならない場合がある.本論 文の目的は,セルアニメのようなキャラクタを,トゥーン シェディングを用いて描く際に,アニメーターはキャラクタ に対して,どういった光源を設定したら良いのか最適解を求 める事である.実写撮影と同じ手法で,キャラクタに対して ライティングを行い,その陰影がセルアニメにどれほど近づ けるかについて試みた.そして,2灯のライトのみでセルア ニメには不要な陰影を消し去る事に成功した.

This report is based on case studies of village religious-ceremony organization in the New Territories (formerly, Xin'an Prefecture), Hong Kong. Comparisons are drawn between similar groups in China and Japan.<br> Focus is on the structure of large-scale religious ceremonies in the New Territories. Every five or ten years, eighty percent of the villages carry out ceremonies that can extend for a week. They are called 'Great Peace Purification Sacrifices' 太平清醮. Entire villages participate, groups of Daoist priests and troupes of actors are invited, and activities are performed day and night for anywhere from three days (and four nights) to six days (and seven nights). To console the spirits and gods, courtesies are extended, offerings presented, and plays performed on their behalf. <br> A distinguishing feature of the 'Great Peace Purification Sacrifice' is the way that the names of all clan members are repeatedly read aloud, one by one. At the shortest of ceremonies (three days and four nights), the recitation can be repeated a halfdozen times or more.<br> The sequence is as follows:<br> 'First Submission to the Gods': For the first day, during the third lunar month, certain formalities are carried out in preparation for the ceremonies proper. Facing away from the village temple and directing themselves to the gods above, Daoist priests read aloud the names of clan members from the entire village, calling out the names that have been recorded for submission: heads of households, their wives and concubines, unmarried brothers and sisters, married sons, daughters-in-law, unmarried children, grandsons and their wives, unmarried grandsons, granddaughters, great grandsons and their wives, and so on. But women's first names are neither recorded nor read aloud. As there are cases of more than two hundred names, and since the calling out of the names can be lengthy, the task of reading aloud is divided among the priests.<br> 'Second Submission': On the second preparatory day, in the middle of the eighth lunar month, the same formalities are carried out.<br> 'Third Submission': The beginning of the tenth lunar month marks the first day of the ceremonies proper. Prior to the performance of sacrifices, clan names are read aloud before the temple a third time, again by multiple priests.<br> 'Opening Announcement': Over the beginning of the same month, the list of village members is posted on the public-square bulletin board. Inscribed in black calligraphy on large red paper, it can be as wide as six feet. Daoist priests again divide up the task of reading aloud the names.<br> 'Inviting the Gods': On a night during the first ten days of the month, after they invite the highest gods from heaven, one of the Daoist priests reads aloud the roster of villager names.<br> 'Begging Pardon': On the last day of the religious ceremony, again during the first third of the tenth lunar month, a Daoist priest reads aloud the list of villager names inscribed in vermilion ink on yellow paper three-feet wide. The document reports to heaven that villagers, having unintentionally committed sins, beg the gods' pardon.<br> In addition, the head-worshipper of the village often carries the community roster and accompanies the Daoist priests while the latter perform prayer ceremonies and make a 'circuit' to pay respects to the gods. Although villagers do not read aloud names on the roster, they always have clearly in mind that everyone in the village is participating.<br>(View PDF for the rest of the abstract.)

近年,製品の低価格化と高品質を両立させるため,物流システムの効率化による流通コストの削減が求められている.また,小売店の効率経営,インターネット通販の拡大のニーズから多品種少量物流の要請も高まっている.多品種少量物流における集配倉庫の出荷作業では,各オーダーに臨機応変に対応するため,人手に頼っていることが多い.出荷の主要作業はマニュアルピッキングであり,作業時間分析の結果では,歩行時間が作業時間の約52%を占めることが示されている.すなわち,冗長な歩行の低減によるピッキング効率向上は作業コスト低減に大きく寄与すると考える. そこで本研究では,多品種少量物流におけるトータルピッキング作業のモデル化および遺伝的アルゴリズムを用いた巡回経路自動導出法の検討を行った.また,小規模の倉庫を模擬してシミュレーションを行い,自由巡回と比較して提案手法が効率的な経路を選択できることを明らかとした.

In this paper, we propose a method to identify commands by analyzing three kinds of lip motion features: lip width, length, and ratio of width and length. Our experimental results for twenty kinds of commands, spoken by nine persons, suggest that the proposed method is suitable for identifying various commands.

There are a number of unclarified points regarding the impact phenomena and the optimum design of tennis rackets. The present study is based on the idea that the dynamics of a racket consists of the dynamics of a rigid body with an arm swing given at a grip as a boundary condition, an impact between a ball and strings with racket frame as an input force, and the structural vibration of the racket. In this paper, impact force and impact duration are investigated, considering the strong nonlinearity of the restoring force of ball and strings. Furthermore, the coefficient of restitution of the tennis racket is estimated using a personal computer on the basis of the impact phenomena and the experimental modal analysis. In order to predict the contact duration, which has an influence on the racket vibration, a simple impact model has been proposed, i.e., that the contact duration is determined by the natural period of a whole system composed of the mass of the ball, the stiffness of the ball and strings, and the reduced mass of the racket at the impact point on the racket face. The calculated results agree fairly well with the experimental results.

The purpose of this study was to quantify the contribution of the whole-body joint torques to the generation of evaluation values during baseball batting motion, such as bat head speed and angular motion of the lower trunk in consideration of the joint torque generating mode. The whole-body segments and bat were modeled as a system of sixteen-rigid linked segments, and constraint axes of the elbow, wrist, knee and ankle joints were modeled with anatomical constraint equations in order to consider the degree of freedom (DOF) of the joint. Each hand was considered to be connected with the bat through zero DOF joint. The equation of motion with respect to the whole-body and bat was obtained by considering modelling errors, such as, residual joint force and moment, and fluctuation of segment's length. The dynamic contributions of the joint moments, motion dependent term and gravity term to the bat head speed and angular motion of the lower trunk were derived from the equation of motion for the system. Furthermore, the joint torque was divided into two components, such as eccentric torque component, which shows negative sign of its torque power, and concentric torque component, which shows positive sign of its torque power. The results obtained in this study showed that 1) motion dependent term was the great contributor to the generation of bat head speed and 2) major contributors to the generation of the bat head speed, such as concentric components of knob-side shoulder abduction torque and torso joint rotational torque were quantified by considering main generating factor of motion dependent term.

Motion-dependent term (MDT), which consists of centrifugal force, Coriolis force and gyroscopic effect moment expressed in the equation of motion for a multi-link system, plays significant roles in the generation of bat head speed through not instantaneous effect but cumulative effect of the exerting joint torques in baseball batting. According to our previous studies that calculate dynamics contributions of the whole-body joint torques considering generating factor of the MDT, the forward/backward rotational torque (FBR torque) at torso joint plays a significant role in the generation of bat head speed. These studies, however, show that the lower limb joint torques do not contribute directly to the bat head speed. Therefore, the purpose of this study was to make clear the functional roles of the lower limb joint torques considering the cumulative effect of exerting joint torques. The whole-body with bat was modelled as a system of sixteen-rigid linked segments. The contributions of the lower limb joint torques to the exerting FBR torque at torso joint were quantified through dynamic contribution equation, which relates lower limb joint torques to the torso FBR torque, derived from both dynamics joint force contribution equation of whole-body system and equilibrium balance equation with respect to rotational movement of the lower trunk segment. The results obtained in this study show 1) lower limb joint torque, especially flexion/extension torque at both hip joints, is a large contributor to the generation of the torso FBR torque, and 2) lower trunk inertial force term and other terms are small contributors to the FBR torque. The development of this analytical method would enable us to quantify the contribution of the lower limb joint torques.

Previous studies, which calculate dynamic contributions of the whole-body joint torques to the generation of bat head speed by using the equation of motion for whole-body with bat system, showed that the motion-dependent term is the largest contributor to the generation of the bat head speed at the ball impact, and also showed that joint torques of the upper limb joints and the torso joint are the main contributors to the head speed with consideration of the generating factors of the motion-dependent term. These results do not tell us the roles of the lower limb joints in the bat head speed generating mechanism. So in order to quantify the roles of the lower limb joints in the mechanism, we quantify the dynamic contributions of the whole-body joint torques to the generation of forward/backward rotational motion of the lower trunk segment during baseball batting motion. Five collegiate baseball players participated in this experiment. They performed hitting a teed ball as strong as possible. Kinetic data of each hand and each foot were obtained by using an instrumented bat equipped with 28 strain gauges and 3 force platforms, respectively. From the results, the flexion/extension torque of both hip joints showed the largest contribution to the forward angular velocity of the lower trunk segment against the large negative contribution due to the torso joint torque. This result indicates that these hip joint torques play an important role to exert large rotational torque at the torso joint, and these hip joint torques show indirect contributions to the bat head speed.
