the finite collinear metal rod impact between the penultimate and ultimate masses, imparting shock pulses in excess of 20,000G for an impact velocity of approximately 4.2m/s. For stand-alone application or as an attachment to a drop table, the machine represents a small-scale and inexpensive alternative

approximation, in which strong fields are allowed but velocities are required to be small. We derive the corresponding equations and speculate on their possible physical consequences. 1 Formulation of the Problem Need for approximations to General Relativity. Since its discovery in 1915 and its first

In a previous paper we have proposed a non–Newtonian, phenomenological description of the effective gravitational force acting between exotic dark matter and baryons, which was shown to fit well the kinematics in the inner regions of low surface brightness, gas–rich galaxies. The Gravitational Suppression (GraS) scheme is, admittedly, an ad-hoc model; it does however successfully address interesting cosmological issues. Here, we test the potential generality of the GraS concept. GraS predictions on motions on scales measurable in dwarf spheroidal galaxies and in the solar neighborhood show significant departures from those of Newtonian mechanics. By analyzing such systems, we find that the paradigm of a universal GraS potential cannot be rejected. Indeed, compared to Newtonian predictions, GraS provides a better description of data, when realistic dark matter density profiles are considered.

(Communicated by the associate editor name) Abstract. A small Knuden number analysis of a kinetic equation in the dif-fusive scaling is performed. The collision kernel is of BGK type with a gen-eral local Gibbs state. Assuming that the flow velocity is of the order of the Knudsen number, a Hilbert

We present a method for simulating water and smoke on an unrestricted octree data structure exploiting mesh refinement techniques to capture the small scale visual detail. We propose a new technique for discretizing the Poisson equation on this octree grid. The resulting linear system is symmetric

Abstract- The use of state of art instrumentation systems to measure high-speed events has increased tremendously in the past few decades. The current study aimed at measuring the velocity of small caliber projectiles within the desired limits of accuracy. The velocity of the projectile
