We investigate a power line communications (PLC) scheme that could be used to enhance the HomePlug 1.0 standard, specifically its ROBO mode which provides modest throughput for the worst case PLC channel. The scheme is based on using a low-density parity-check (LDPC) code, in lieu of the concatenated Reed-Solomon and convolutional codes in ROBO mode. The PLC channel is modeled with multipath fa...

Vibratory manipulation is any mode of manipulation involving repeated impacts due to a striker which follows some periodic motion. In this paper, we study vibratory manipulation in the context of tapping planar objects which slide on a fixed support surface. We are interested in the behaviors an object exhibits under such excitation. There are two distinct types of tapping that can result: cont...

In this paper, we describe a new and computationally efficient adaptive system for the enhancement of autoregressive (AR) signals which are disturbed by additive white or colored noise and impulsive noise. The system is comprised of an adaptive Kalman filter operating as a fixed lag smoother and a subsystem for AR parameter estimation. A superior performance is achieved by implementing a feedba...

Children differ considerably in the social-information-processing (SIP) patterns underlying their aggressive behavior. To clarify these individual differences, we propose a dual-mode SIP model that predicts which processing steps children will take, take them, and under circumstances, how this may lead to aggression. This distinguishes between an automatic reflective mode. The mode is character...

We demonstrate the creation and measurement of shaped multimode vibrational wave packets with overtone and combination mode excitation in CCl4. Excitation of wave packets through nonresonant impulsive stimulated Raman scattering allows for coherent control of molecular vibrations without passing through an electronic resonance. This technique is therefore very general and can be implemented in ...

In a search for a positive model of decision-making with observable primitives, we rely on the burgeoning literature in cognitive neuroscience to construct a three-element machine (agent). Its control unit initiates either impulsive or cognitive element to solve a problem in a stationary Markov environment, the element “chosen” depends on whether the problem is mundane or novel, memory of past ...

Animals show impulsiveness when they prefer a smaller more immediate option, even though a larger more delayed option produces a higher intake rate. This impulsive behavior has implications for several behavioral problems including social cooperation. This paper presents two experiments using captive blue jays (Cyanocitta cristata) that consider the effects of payoff accumulation and temporal c...

A recently proposed by the authors impulsive mathematical model of non-basal testosterone secretion of the hypothalamic-pituitary-testicular axis in the male is considered. Conditions for existence of periodic solutions in the model, their parametrization and stability are studied. Parameter bifurcations which lead to periodic oscillations of hormone levels with one or two pulses of gonadotropi...

Fractional differential equations have been of great interest recently. This is because of both the intensive development of the theory of fractional calculus itself and the applications of such constructions in various scientific fields such as physics, mechanics, chemistry, engineering, etc. Differential equations with impulsive effects arising from the real world describe the dyn...
