We investigate the problem of ballistically controlled reactions where particles either annihilate upon collision with probability p, or undergo an elastic shock with probability 1-p. Restricting to homogeneous systems, we provide in the scaling regime that emerges in the long time limit, analytical expressions for the exponents describing the time decay of the density and the root-mean-square ...

OBJECTIVES Mechanical and neuromuscular benefits arise during ballistic stretch-shortening cycle muscle activation, yet resistance training regimens are typically non-ballistic, and in contrast to ballistic movement, require a concentric deceleration phase. DESIGN Twelve healthy males performed a unilateral, six repetition maximum non-ballistic elbow flexion-extension task during; (i) rapid s...

forming limit diagram (fld) is an important diagram by which the formability of sheet metals is studied. strain rate is a very effective parameter influencing the fld which is, in turn, influenced by the forming velocity. in this work, forming limit diagram for st14 was investigated both experimentally and numerically. in addition, the effect of forming velocity was studied and the experiments ...

Abstract In order to study the penetration ability of fragment simulation projectile(FSP) armored steel target, and detect protection target plates with different thicknesses. Combined numerical experiment, process FSP on thickness ratios is studied. The design implementation preparations were made for damage plate by fragments, relevant data obtained analyzed. analysis results show that finite...

We conducted an experimental and analytical study to understand the mechanisms and dominant parameters for ogive-nose rods and 7.62mm APM2 bullets that perforate 5083-H116 aluminum armor plates. The 20-mm-diameter, 95-mm-long, ogive-nose, 197g, hard steel rods were launched with a gas gun to striking velocities between 230-370m/s. The 7.62-mm-diameter, 10.7g, APM2 bullet consists of a brass jac...

This paper presents an investigation on energy absorption characteristics of nano-reinforced panels, laminated face sheets and sandwich composites in high velocity ballistic and low velocity punch-shear experiments. The vinyl ester panels were reinforced with 1.25 and 2.5 wt. percent nanoclay and exfoliated graphite platelets. Three different face sheets were manufactured with E-glass, Owens Co...

Future MOS transistors may operate near their ballistic limits [1], so it is important to understand ballistic device physics and the prospects for achieving quasi-ballistic operation. In this paper, we explore the device design and physics issues of MOSFETs at the scaling limits using semiclassical and full quantum simulations. The device we presume is a double-gate (DG) MOSFET with symmetrica...

This paper presents the calibration of novel kinetic velocity model (KVM) in drift-diffusion (DD) transport approach, which can account for ballistic effect short-channel devices. The KVM considers a thermionic emission limit and free carrier acceleration mobility. We develop methodology to extract parameters high-field saturation SiGe nanowires over whole mole fraction range. calibrated DD sim...

Rumsey, D.W. M.S., Purdue University, December 2001, Electrical Characterization of Bulk MOSFETS in Terms of Backscattering Coefficients. Major Professor: Mark S. Lundstrom As the end of the roadmap for semiconductor devices is approached, channel lengths are shrinking, and drain current demands are remaining high. Current day devices operate in a quasi-ballistic regime. In order to assess devi...

Discrete response of structures often is a key probabilistic quantity interest. For example, one may need to identify the probability binary event, such as whether structure has buckled. This study used an adaptive domain-based decomposition and classification method, combined with sparse grid sampling, develop efficient surrogate modeling algorithm for discrete outputs. An assumption monotonic...
