A Proposal of a Numerical Computation Method for Dynamic Responses of Complicated Systems having Structures and Living Bodies with Reaction

 [Abstract]
A fast finite element method is proposed to compute dynamic properties for complicated systems having elastic/viscoelastic structures and living bodies with reaction. We proposed an expressions of modal damping by applying asymptotic expansion to complex eigenvalue problem of the dynamics systems. We can analyze modal couplings in damping of the complicated dynamics systems. This method is named as MSKE (Modal Strain and Kinetic Energy) Method. This method is extended for the systems having nonlinear restoring force with linear/nonlinear hysteresis. This proposed method can be applied to calculate impact responses of soft structures. This method is extended to complex nonlinear restoring force element to compute impact responses of interaction systems between alive human bodies and machines (e. g. robots and vehicles) using complex coefficients for the nonlinear restoring force. We applied this method to obtain impact responses for alive human bodies under contraction and relaxing condition of muscle, Negative values are given for the imaginary parts of the nonlinear restoring force element to consider effects of foresight, precaution and panic on the behaviors in the calculation.

Will every streetlight have network cameras in the near future?

 [Abstract]
A street camera network, in which many IP cameras are installed at a high density, similar to street lights throughout a nation, will have a stronger positive effect in suspect tracking and crime deterrence in the near future. On the other hand, it will also have a stronger negative effect related to the violation of privacy of ordinary citizens. In order to make such a stronger surveillance camera system, which forcibly captures the images of passersby for the public interest, be accepted as an essential social infrastructure by a society, it is necessary for this camera system to make ordinary citizens be convinced that it is used only for the public interest. To realize this, a new concept, in which the abuse of a street camera network is deterred by recording and disclosing browsing-history, is proposed. The perspective on the street camera system in the near future is discussed.

Control and estimation techniques for electric power steering systems

 [Abstract]
Electric power steering has a bright future as autonomous driving and active safety systems for vehicles. Resent controlling and diagnosing electric power steering systems requires an understanding of not only vehicle dynamics but also state variables. In this talk, estimation and control methods for EPS systems including the proposed methods based on advanced control theories will be presented.

Pyrolysis of Municipal Solid Wastes: Cebu’s Energy Solution for Environmental Problems

 [Abstract]
The Philippines is faced with environmental as well as energy crisis. Included in the environmental crisis is the perennial problem of Municipal Solid Waste (MSW) disposal. Pyrolysis is the transformation of a substance into another compound by the application of heat alone. In the context of energy, pyrolysis is the heating of organic materials in the absence of oxygen with provisions for the recovery of the desired combustible products. This paper will attempt to show that pyrolysis is one of the solutions for both the energy and environmental problems. Pyrolysing Cebu’s almost 500 tons/day of MSW would produce approximately 11,250 kg/hr of pyrolysis gas. This amount of gas would fuel a gas turbine system to generate almost 5.0 MW of electricity.

Review of the Levitation Mass Method (LMM)

-    A Precision Method for Measuring Mechanical Quantities -

 [Abstract]
The present status and the future prospects of the Levitation Mass Method (LMM), which is a method for precision mass and force measurements, are reviewed. The LMM has been proposed and improved by the author. In the LMM, the inertial force of an inertial mass levitated using a aerostatic linear bearing is used as the reference force applied to the objects under test, such as force transducers, materials or structures. The inertial force of the levitated mass is measured using an optical interferometer. Major applications of the LMM, such as dynamic calibration for force transducers, material testers without use of force transducers and the mass measurement device (MMD) for use in the International Space Station (LMM), are reviewed.

Review of the Levitation Mass Method (LMM) drop-ball test

 [Abstract]
The present status and the future prospects of the Levitation Mass Method (LMM) drop-ball test are reviewed. The LMM has been proposed and improved by the author. In the test, a spherical, body containing a cube corner prism which is arranged so that its optical center coincides with the center of gravity is dropped from an initial height to the clay under test. The velocity is measured using an optical interferometer as the function of the Doppler shift frequency which is defined as the difference between the beat frequency and the rest frequency. The position and acceleration of the spherical body is calculated by differentiating and integrating the velocity, respectively. Force acting on the spherical body is calculated as the product of the mass and the acceleration of the spherical body. Major applications of the LMM drop-ball test, such as Impact force measurement of a spherical body dropping onto a water surface [1], Impact force measurement of a spherical body dropping onto a polyurethane sheet [2], Impact force measurement of a spherical body dropping onto sand particles [3], are reviewed.
