Abstract The paper deals with the problem of motion of human upper limb so that to be ensured the success of the throw in basketball game. For the human upper limb there was considered the model of double pendulum. The classic equation of motion of the ball was correlated with the corresponding equation of motion for the upper limb, so that the ball to pass through the basket. It is well known that the trajectory of a thrown body is a parabola.
The equations of position and velocity of the hand are written and give the initial conditions for the fly… More >

Abstract In the electrostatic-structural problems as encountered in many electrostatic driven MEMS devices, the electrostatic analysis domain is often extremely distorted due to the deflection of the structure. This kind of problem is difficult to deal with by almost all kinds of available numerical methods. A new three-dimensional meshless scheme with background grid is thus proposed herein to solve those difficulties in numerical simulations.
By this scheme, a three-dimensional fixed background grid with regularly distributed nodes is utilized. Another set of discretized boundary grid is employed to describe both the surface boundaries of the structure and the electrostatic field. The analysis… More >

Abstract The objective of this paper is to propose a novel press of Stephenson type, and verify its feasibility. First, the system is presented and its advantages are discussed. Then, the kinematic analysis of the system is obtained by examining the geometry of the design. Finally, a design example is given to verify the feasibility of the design by conducting computer simulation. All the above analysis and design are illustrated by using Stephenson type mechanism. The results show that the developed system is feasible and with high potential to be applied to a press for precision forming. More >

Abstract The main target of the present paper is the analysis of the fracture mechanics behavior of delaminated composite structures actively repaired through piezoelectric patches. The aim at issue has been achieved by using a boundary element code implemented to study piezoelectric solids, including, as limiting case, the applicability to linear elastic anisotropic materials. The assembled structures, made up of the damaged composite components and the piezoelectric patches, have been modeled through the multidomain technique. To take into account for the adhesive layer among the host structure and the active patch, an interface spring-model has been also implemented. The multidomain technique… More >

Abstract In this study, fire simulations were performed to analyze the characteristics of the fire driven flow and the effects of the platform screen door on the smoke flow in the station, when the fire occurred in the center of the platform. Soongsil Univ. station (line number 7) was chosen which is the one of the deepest (47m) underground subway stations in the Seoul metro(SMRT). The parallel computational method was employed to compute the heat and mass transfer eqn's with 6 CPUs of the Linux clustering machine. The fire driven flow was simulated using FDS code in which LES method was… More >

Abstract It is a common practice that most underground basements of buildings are utilized/developed for commercial purposes/stores in Taiwan. Many basement fires occurred and caused tremendous losses of human lives and properties in the past twenty years. Therefore protecting against basement fires in commercial buildings is of important concern in Taiwan. Smoke gases from a basement building fire might spread through corridors and ventilation systems to the entire building. This study utilizes Fire Dynamics Simulator (FDS) software to develop a computer simulation model for investigating a typical basement barbershop fire that occurred in 1993. The fire accident eventually/ unfortunately caused a… More >
