Velocity Measurement System for Small Caliber Projectiles

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 is calculated by dividing the distance between two downrange measurement locations, by the difference of the time when ...

Numerical Simulation of Impact of Low Velocity Projectiles With Water Surface

In this article, Finite Element Method (FEM) and Eulerian-Lagrangies Algorithm (ELA) formulation were used to numerically simulate the impact of several low-velocity projectiles with water surface. Material models which were used to express behavior of air and water included Null material model. For the projectiles, rigid material model were applied. Results were validated by analyzing the impa...

Vortical Projectiles from Shock - Bubble Interactions

We introduce the concept of a moving \vortical projectile" (VP) to synthesize a new understanding of vortex dynamics in the vicinity of interacting nearby layers or structures of opposite-signed vorticity. In particular those layers deposited at contact surfaces when a shock or blast wave interacts with a spherical or elliptical bubble, heavier than ambient. This concept is generic to complex s...

Soft X-rays from High-Velocity Clouds

The ROSATmission gave us the unique possibility to study the galactic interstellar medium by “shadowing” observations on arcmin angular resolution level. The high sensitivity of the ROSAT PSPC in combination with the large field of view allows the detailed study of individual clouds, while the ROSAT all-sky survey is the main source for studies of the large-scale intensity distribution of the d...

High-resolution, high-SNR velocity maps reconstructed from low-resolution Fourier velocity encoded MRI data

Introduction: Fourier velocity encoding (FVE) provides considerably higher SNR than phase contrast (PC), due to its higher dimensionality and larger voxel sizes. FVE is also robust to partial voluming, as it measures the velocity distribution of the spins within each voxel. FVE data are typically acquired with low spatial resolution, due to scan-time restrictions associated with its higher dime...
