[[alternative]]The effect of mental training on the performance of basketball free-throw

[[abstract]]本研究旨在探討心智訓練對籃球平常時罰球技能及比賽時罰球技能表 現的影響, 以及降低比賽時狀態性焦慮之關係; 研究對象為五專男子籃球 選手14名, 隨機分派各7 名至實驗組( 心智訓練加上身體練習 )及控制 組( 僅從事身體練習 ); 實驗所得之資料以二因子混合( 一獨立, 一重複 )變異數分析( split-plot )處理. 若二因子之間交互作用達顯著水準時, 則進一步就單純主要效果( simple main-effect )加以考驗. 基於本研究 之研究範圍及限制, 根據實驗結果經由討論而獲得以下四點結論: 一. 身體練習或身體練習加上心智訓練對提昇籃球平常罰球技能表現皆具 有效果. 二. 身體練習加上心智訓練對提昇籃球平常罰球技能表現 上比僅有身體練習更具有效果. 三. 身體練習加上心智訓練對提昇籃球比 賽時罰球命中率上具有效果, 而無心智訓練之身 體練習對提昇比賽時 罰球命中率上並無效果. 四. 身體 練習或身體練習加上心智訓練對降低比賽時狀態性焦慮上並無效果.

曲線管要素を用いた配管系の曲げ振動低減による振動騒音伝達の抑制法

Bending vibrations of a pipe system are trasmitted to an evaporator and generate noise in an air conditioning system. Hence to reduce noise, bending vibrations should be reduced. This paper presents a method for reducing bending vibrations of a pipe system by use of curve tube elements. As a first step, to discuss the validity of the simulation program based on our previous analyses, experimental tests have been performed, and the simulation results are compared with the experimental data for some typical cases. Then, the bending vibrations are calculated for pipe systems with the proposed curved tube elements. It is clarified that the method presented plays an important role in reducing bending vibrations in the pipe system

粘弾性内部支点を有する粘弾性空間曲りはりおよび真直はり結合系内の振動伝達とファジィ推論による内部支持位置の最適化

This paper presents a method for obtaining vibration response of a viscoelastic spiral rod having straight portions on viscoelastic supports. The expressions for calculating frequency response are obtained by means of the transfer matrix method, in which the exact solution of the differential equations with twelve state variables for the static deflection is applied. Inertia forces and rotatory inertia are included by making use of the point transfer matrix, and the bent portions are also considered by including the transfer matrix of coordinates. Numerical calculations were carried out for the rod with both an elastic portion and a viscoelastic portion carrying a mass at the end. In this problem, the rotary vibration is of importance because it generates noise, hence the location of the viscoelastic support which induces the rotary vibration of the mass minimum is discussed in detail. The fuzzy algorithm by which the optimal location of the supports is obtained is also presented

内部に支点を有する空間曲りばりと直線棒の結合系の振動

This paper discusses free vibrations of a spiral rod with straight portions on a number of supports. Since the spiral portion is a three-dimensional structure, three-dimensional motions are coupled. Hence, this paper first presents the transfer matrix for a three-dimensional curved rod with supports, then the transfer matrix of a straight rod with supports is joined to that of the spiral rod. The frequency equations for the rod with consideration of three-dimensional motions are obtained. Numerical calculations are carried out for some typical problems

圧電・電磁アクチュエータによる柔軟構造物の大変形姿勢制御

This paper proposes an actuator consisting of a piezoelectric element, two electromagnets and a spring for controlling displacement of flexible beam with large deflections. The voltage pattern for the piezoelectric element and the electric current patterns for the magnets and the relationship between the actuator displacement and the deflection of a beam are presented. The experimental tests are also caried out. It is ascertained that the proposed actuator has some advantages as compared with the general deflection control apparatus using a motor
