We study the properties of the transversal Killing and twistor spinors for a Riemannian foliation with a transverse spin structure. And we investigate the relations between them. As an application, we give a new lower bound for the eigenvalues of the basic Dirac operator by using the transversal twistor operator.

For developing automotive parts and telematics devices the real car test often shows limitation because it needs high cost, much time and has the possibility of the accident. Therefore, a Vehicle Driving Simulator (VDS) instead of the real-car test has been used by some automotive manufactures, research centers, and universities. The VDS is a virtual reality device which makes a human being feel as if one drives a vehicle actually. Unlike actual vehicle, the simulator has limited kinematic workspace and bounded dynamic characteristics. So it is difficult to simulate dynamic motions of a multi-body vehicle model fully. In order to overcome these problems, a washout algorithm which restricts workspace of the simulator within the kinematic limits is needed, and analysis of dynamic characteristics is required also. However, a classical washout algorithm contains several problems such as time delay and generation of wrong motion signal caused by characteristics of filters. Specially, the classical washout algorithm has the simulator sickness when driver hardly turns brakes and accelerates the VDS. In this paper, a new washout algorithm is developed to enhance the motion sensitivity and improve the simulator sickness by using the vehicle tilt signal which is generated in the real time vehicle dynamic model.

Reengineering, also known as a business process redesign, involves a fundamental rethinking, and often a radical redesign, of an entire business process or a set of process to achieve dramatic improvements. The central paradox of reengineering is that its own advantages constitute the greatest threat to its success. For reengineering to be the right choice, the organization must have real capacities to embrace changes across the board. The key is to begin with, and to preserve, a vision of the new order, which drives this structured approach, and is in turn calibrated by that approach. However, in most cases of these calibrations, the empirical evidences on the effect of determinants in the reengineering are required. Seemingly, the research results in this area are scarcely verified. This article tried to search the effect of four dimensions of the reengineering toward the performance of reengineering. The results showed that the factors of the organization behavior and of the methodology/operation had more affected on the performance.
