We present full modelling of tangent point emission of HI as seen in the 21cm transition in the inner Galaxy. We measure the scale height and velocity dispersion of HI as a function of Galactic radius besides the rotation curve and the z-centroid of the atomic layer. The model used takes into account emission from a large path length along the line of sight, corresponding to an interval ( R) of...

A near-optimal midcourse trajectory shaping guidance algorithm is proposed for both air and ballistic target engagement mission attributes for generic long range interceptor missile. This guidance methodology is based on the maximum final velocity as the objective function and maximum permissible flight altitude as the in-flight state constraint as well as the head-on orientation as the termina...

This paper presents the determination of a concentration at the minimum bubble velocity (CMV) for different types of frothers, such as straight and branched alkyl chain aliphatic alcohols, 1,ω-diols, poly(propylene glycol) and poly(ethylene glycol) alkyl ethers, n-alkyltrimethylammonium bromides, commercial frothers and others. The values of terminal rise bubble velocity were reviewed from the ...

The pressing need for accurate and reliable precipitation measurements forecasting poses theoretical technological problems. Remote-sensing instruments with increased coverage sensitivity (such as space-borne ground-based radar) are available; however, their full exploitation requires physical calibration validation based on a deep knowledge of microphysics. This study reports detailed analysis...

A simple setup was assembled to study the motion of an object while it falls. The setup was used to determine the instantaneous velocity, terminal velocity and acceleration due to gravity. Also, since the whole project was done within $20 it can easily be popularized.

Droplet motion is important in discrete microfluidic operations as well as in emerging site-specific cooling techniques based on electrowetting. The present work reports on carefully characterized experiments that map the shape, advancing and receding contact angles, and contact area of droplets sliding under gravitational actuation as a function of droplet size and velocity. A pseudo-Lagrangia...

The performances of bulk microphysical schemes were evaluated through comparisons with observations, including a new volume scanning video disdrometer targeting one typical snowfall event in Hokkaido, Japan. For the evaluation, downscaling experiments using three conducted: two-moment scheme, one-moment and an improved version scheme coupled identical dynamical core. successfully simulated meas...

We propose a backstepping global fast terminal sliding mode control for trajectory tracking of industrial robotic manipulators in this article. An integral the surface is firstly suggested to improve dynamic performance and convergence Sliding Mode Control (SMC) Terminal SMC (TSMC), which also obtains finite-time convergence. A controller then developed from proposed using method High-Order (HO...

We demonstrate that a three-terminal harmonic symmetric chain in the presence of a Coriolis force, produced by a rotating platform that is used to place the chain, can produce thermal rectification. The direction of heat flow is reconfigurable and controlled by the angular velocity Ω of the rotating platform. A simple three-terminal triangular lattice is used to demonstrate the proposed principle.
