the large amount of computation necessary for obtaining time optimal solution for moving a manipulator on specified path has made it impossible to introduce an on line time optimal control algorithm. most of this computational burden is due to calculation of switching points. in this paper a learning algorithm is proposed for finding the switching points. the method, which can be used for both ...

We study the phase dynamics of a chain of autonomous oscillators with a dispersive coupling. In the quasicontinuum limit the basic discrete model reduces to a Korteveg-de Vries-like equation, but with a nonlinear dispersion. The system supports compactons: solitary waves with a compact support and kovatons which are compact formations of glued together kink-antikink pairs that may assume an arb...

Two-dimensional Direct Simulation Monte Carlo (DSMC) simulations are carried out for investigating the shock wave propagation and boundary layer effects in a shock tube flow, for a wide range of rarefied conditions. Nitrogen is used for all simulations. The Cercignani-Lampis-Lord (CLL) model of gas surface interactions is implemented to study the effects of boundary layer which develops behind ...

Using data from a 4-wave longitudinal study with a school-based sample of 1,218 middle adolescents, the authors investigated the directionality (e.g., unidirectionality and bidirectionality) of the prospective relationship between depressive symptoms and cigarette use within the context of potential confounding variables and common and unique intrapersonal and interpersonal predictors. Findings...

In this paper, it is shown completely analytically that a spintessence model in the dust dominated universe can very well serve the purpose of providing an early deceleration and a present day acceleration. The stunning results of the observations on the luminosity redshift relation of some distant supernovae [1, 2], that the universe is currently undergoing an accelerated phase of expansion, p...

Various coagulation tests like Prothrombin Time (PT) and Activated Partial Thromboplastin (APTT) are estimated by automated analyzers. The newer fully analyzers generate clot wave forms aPTT-CWA for these parameters derived. In this study, the objective was to analyze form characteristics morphology its first second derivative values in cases with abnormal APTT. ACL TOP 300 generated curves APT...

We present the coupling of torsion scalar T and trace energy-momentum tensor $\mathcal {T}$ , which produces new modified f ( ) $f(T,\mathcal {T})$ gravity. Moreover, we consider functional form = α + β 2 {T}) =\alpha \mathcal {T}+\beta T^2$ where are free parameters. As an alternative to a cosmological constant, theory may offer theoretical explanation late-time acceleration. The recent observ...
