The aim of this paper focused on obtaining the optimum cruciform geometry of reinforced magnetorheological elastomers (MRE) to perform homogeneous equibiaxial deformation tests, by using optimization algorithms and Finite Element Method (FEM) simulations. To validate the proposed specimen geometry, a digital image correlation (DIC) system was used to compare experimental result measurements wit...

Differential Game Based Guidance Law for High Angle of Attack Missiles By P. K. Menon and G.B. Chatterji Optimal Synthesis 450 San Antonio Road, Suite 53 Palo Alto, CA 94303 Abstract A nonlinear differential game theoretic intercept guidance law for short range missiles is derived. Differential geometric transformations are used to convert the nonlinear missile and the target models into a conv...

Dr. James Clay Moltz is Assistant Director and Research Professor at the Center for Nonproliferation Studies of the Monterey Institute of International Studies. He has published widely on Russian Far Eastern and East Asian security issues. The rise of theater ballistic missile capabilities in East Asia—particularly in China and North Korea—has raised fears among the United States, South Korea, ...

In this paper, a Time-to-go Polynomial Guidance (TPG) law satisfying impact angle constraints for missiles of time-varying velocity against stationary target is investigated. The guidance law assumes the magnitude of guidance commands as a polynomial function of time-to-go with two unknown coefficients. The coefficients are determined to satisfy the two terminal constraints, which are the termi...

Two major simultaneous attack strategies have been introduced, as one of cooperative attack of multiple missiles. One strategy is an undesignated time attack, in which the missiles communicate among themselves to synchronize the arrival times by reducing the mutual differences of times-to-go of multiple missiles during the homing. The other is a designated time attack, in which a common impact ...

We sometimes fail to notice unexpected objects or events when our attention is directed elsewhere, a phenomenon called inattentional blindness. We explored whether unexpected objects that shared the color of consequential objects would be noticed more often. In three pre-registered experiments, participants played a custom video game in which they avoided both low- and high-cost missiles (Exper...
