in this paper a new guidance technique for ballistic missiles and launch vehicles is proposed. generally the lambert guidance is used to generate missile nominal (correlated) parameters through powered flight to put it in a ballistic flight path. because of uncertainties and undesired factors, the nominal position and velocity obtained by lambert technique need to be followed in actual flight. ...

Co-Continuous Ceramic Composites, referred to as C4, have bi-continuous, interconnected and interpenetrating phases of a metal and ceramic. This bestows such composites with a higher strength to weight ratio compared with traditional composites. In this research work, a C4 composite of AA5083/SiC is fabricated for personal body armour, using gravity infiltration technique. A numerical simulatio...

We investigate the kinetics of generic single-species reaction processes when the reactants move ballistically, namely ballistic annihilation, A + A 0, and a ballistic aggregation process which mimics traffic flow on a single-lane roadway. For ballistic annihilation, dimensional analysis shows that the concentration and root means square velocity decay as c P and u N r-6, respectively, with a +...

Inverse modeling of state-of-the-art NMOSFETs is used to investigate electron transport models and in particular to extract the effective velocity of electron injection from source to channel. It is found that this velocity is less than 50% of the maximum possible velocity, i.e. the thermal velocity of electrons in the source. Based on the Landauer formulation, as adapted by Lundstrom to silico...

Abstract The medium-thickness plate penetration enhanced behavior of coupled kinetic energy and chemical reactive fragment was investigated. A series experiments were conducted. After the experiments, High-speed photography images blackening at front compared. results show that enhancement penetrating is related to intensity deflagration plate. Division zones impacting proposed, combine dynamic...

We study numerically the effect of on–site Hubbard interaction U between two electrons in the quasiperiodic Harper's equation. In the periodic chain limit by mapping the problem to that of one electron in two dimensions with a diagonal line of impurities of strength U we demonstrate a band of resonance two particle pairing states starting from E = U. In the ballistic (metallic) regime we show e...

Ohm’s law, a linear drift velocity response to the applied electric field, has been and continues to be the basis for characterizing, evaluating performance, and designing integrated circuits, but is shown not to hold its supremacy as channel lengths are being scaled down. In the high electric field, the collision-free ballistic transport is predicted, while in low electric field the transport ...

Patterns of individual animal movement have been a focus of considerable attention recently. Of particular interest is a question how different macroscopic properties of animal dispersal result from the stochastic processes occurring on the microscale of the individual behavior. In this paper, we perform a comprehensive analytical study of a model where the animal changes the movement velocity ...
