This paper presents new investigations to improve dynamic behavior of electrostatic cantilever based MEMS sensors by reducing pull-in voltage nonlinearity. It is believe that pull-in voltage is one of the major factors to generate pull-in force that induces parasitic pull-in frequency as a result the behavior of MEMS sensor become nonlinear. The dynamic behavior of the device is modeled under the...
The deformation of the cantilever caused by manipulation force is one of the most major nonlinearities and uncertainties during manipulation. It causes difficulties in precisely controlling the tip position, which will cause the tip to miss the position of the object. In order to solve this problem, in this paper, the dynamics model of piezoelectric smart cantilever beam based on ionic polymer metal...
The purpose of this paper is motion analysis by experiment and simulation for riding bicycles with children. It is very important to think about stability when the bicycle is driving with children. However, such a research is not so performed. Therefore, analysing human motions in the such case by some experiments and simulations, dynamic characteristics of the such case are shown. The modeling of...
This article proposes a new method combining convex optimization and viability theory for estimating traffic flow conditions on highway segments. Traffic flow is modeled by a Hamilton-Jacobi equation. Using a Lax-Hopf formula, we formulate the necessary and sufficient conditions for a mixed boundary and internal conditions problem to be well posed. The well-posedness conditions result in a system...
