Fragment velocity distribution of D-shaped casing with multiple fragment layers

Source shape determination with directional fragment-fragment velocity correlations

Correlation functions, constructed from directional projections of the relative velocities of fragments, are used to determine the shape of the breakup volume in Preprint submitted to Elsevier 2 February 2008 coordinate space. For central collisions of Xe + Sn at 50 MeV per nucleon incident energy, measured with the 4π multi-detector INDRA at GSI, a prolate shape aligned along the beam directio...

Fragment-based Visual Tracking with Multiple Representations

Corresponding Author: Junqiu Wang AVIC Intelligent Measurement, Aviation Industry Cooperation China, Beijing, China Email: [email protected] Abstract: We present a fragment-based tracking algorithm that considers appearance information characterized by a non-parametric distribution and spatial information described by a parametric representation. We segment an input object into several fragm...

Fibrinogen and fragment D-induced vascular constriction.

Elevated fibrinogen (Fg) concentration in blood is a high risk factor for many cardiovascular diseases. We hypothesize that Fg and its early degradation product, fragment D, may result in arterial constriction by binding endothelial intercellular adhesion molecule-1 (ICAM-1). The vasoconstriction induced by Fg and fragment D was studied in third- and second-order arterioles (3As and 2As, respec...

Determining Detonation Threshold for Multiple Fragment Impacts

Dual fragment impacts were studied using the Eulerian hydrocode CTH. The purposes of the study were to gain insight into the physical phenomena underlying multiple fragment impacts, and to develop an equation that predicts critical fragment velocity, the velocity at which a fragment must travel to cause a detonation in a covered explosive, for dual fragment impacts. Identical steel fragments we...
