The present work is attentive to studying the qualitative analysis for a nonlinear strain wave equation describing finite deformation elastic rod taking into account transverse inertia, and shearing strain. rewritten as dynamic system by applying particular transformation. bifurcation of solutions examined, phase portrait depicted. Based on constraints, integration first integral along specifie...

Uniformly redundant arrays (URA) have autocorrelation functions with perfectly flat sidelobes. The URA combines the high-transmission characteristics of the random array with the flat sidelobe advantage of the nonredundant pinhole arrays. A general expression for the signal-to-noise ratio (SNR) has been developed for the URA as a function of the type of object being imaged and the design parame...

In this paper we investigate threshold based networks performing 2 1 addition using redundant binary operand representations. In particular we concern with establishing the networks with the smallest network depth assuming small weight and fan-in values. First we propose a depth-4 implementation and we show that the 2 1 addition can be computed by a threshold network with the size in the order ...

Coded aperture imaging uses many pinholes to increase the SNR for intrinsically weak sources when the radiation can be neither reflected nor refracted. Effectively, the signal is multiplexed onto an image and then decoded, often by computer, to form a reconstructed image. We derive the modulation transfer function (MTF) of such a system employing uniformly redundant arrays (URA). We show that t...

Hypotheses regarding patterns of stress, strain and deformation in the craniofacial skeleton are central to adaptive explanations for the evolution of primate craniofacial form. The complexity of craniofacial skeletal morphology makes it difficult to evaluate these hypotheses with in vivo bone strain data. In this paper, new in vivo bone strain data from the intraorbital surfaces of the supraor...

The paper studies the interaction of a longitudinal wave with transverse waves in general isotropic and unconstrained hyperelastic materials, including the possibility of dissipation. The dissipative term chosen is similar to the classical stress tensor describing a Stokesian fluid and is commonly used in nonlinear acoustics. The aim of this research is to derive the corresponding general equat...
