4) Velocity equation 速度方程 1. The extreme conditions of yield condition and yield function are discussed;and a velocity equation is established under the condition that no flow rule has been required. 对屈服条件与屈服函数的极值条件进行了讨论,在不需要流动法则的情况下建立了速度方程。 2. Dee...
This paper proposes an approach for velocity and position estimation through acceleration measurements. In this approach, the noises of acceleration signal are removed through a smoothing process based on diffusion equation, a special partial differential equation (PDE). Then a mechanism is designed to...
III. VELOCITY/POSITION INTEGRATION FORMULAE A. Attitude Integration Formula n Equation (1) shows that the attitude matrix C b is a function of b nb , whose calculation inversely depends on n C b by the relation b nb b ib Cb n n in . n In order to obtain the analytic form of ...
To determine the value of the constant vector ( C), we use the fact that ( v)(0)=( i)-( j)+( k). The preceding equation gives ( v)(0)=( C), so ( C)=( i)-( j)+( k) and (split)( v)(t)&=2t^2( i)+3t^2( j)+t( k)+( i)-( j)+( k) &=(2t^2+1)(...
This is the magnitude of the position vector rather than the velocity vector: √ ((x(2.3))^2+(y(2.3))^2)=1000.(B) This option is incorrect. This error in the calculation of the magnitude of the velocity vector comes from neglecting to square the velocity vector values: √(x'(2.3)...
