This paper investigates the kinematics and dynamics of multi-rigid-body systems in screw form. The Newton–Euler equations are established coordinates. All forces torques system can be solved straightforwardly since they explicit form displacement acceleration unified matrix form, which associates with variable velocity. A one-step numerical algorithm only is needed to solve displacements accele...

In order to overcome the difficulty in aligning specimens accurately within a reference system for angular kinematic measurements, method of using virtual coordinate was designed and implemented conjunction with an optical motion capture device. The is created by digitizing three identifiable points space.

This research develops thermo-elastic analysis of a functionally graded cylinder under thermo-mechanical loadings. Heat conduction equation in cylindrical coordinate system is solved. Thermal conductivity coefficient is graded along the radial direction. By considering a symmetric distribution of temperature, loading and boundary conditions, strain-displacement and stress-strain relations can b...

◆ Collection of 3-D points ● coordinates of points are expressed in object coordinate system ● when we see an image of the object this means that there is an instance of the object in the world ◆ so, we can think of the object model as being transformed to the world coordinate system ◆ think of the world coordinate system as a coordinate system used to describe locations of points in a workspac...

The influence of the geomagnetic field on the development of air showers is studied. The well known International Geomagnetic Reference Field was included in the AIRES air shower simulation program as an auxiliary tool to allow calculating very accurate estimations of the geomagnetic field given the geographic coordinates, altitude above sea level and date of a given event. Some test simulation...
