The Development of High Order Numerical Techniques for Reentry Simulation of Hypersonic Spacecraft [PDF]
, 1991 The primary difficulty encountered when simulating hypersonic flow is that the flow normally includes strong nonlinear discontinuities. These discontinuities fall into three broad classes: shocks, slip-lines, and rarefaction waves.

Developing a Multi-Objective Guidance Scenario for the Entry to the Earthâs Atmosphere [PDF]
فصلنامه علوم و فناوری فضایی, 2014 In this paper, a multi-objective guidance scenario has been developed which could be used to improve the accuracy of sub-orbital modules at the entry to the earth’s atmosphere. Developed algorithm could be used for the trajectory shaping and adjusting of

Entry Dispersion Analysis for the Hayabusa Spacecraft using Ground Based Optical Observation [PDF]
, 2011 Hayabusa asteroid explorer successfully released the sample capsule to Australia on June 13, 2010. Since the Earth reentry phase of sample return was critical, many backup plans for predicting the landing location were prepared. This paper investigates the reentry dispersion using ground based optical observation as a backup observation for radiometric

Implication of the inferior vena cava in the generation of reentry in the pectinate muscles
Revista Facultad de Ingeniería Universidad de Antioquia, 2015 Atrial fibrillation (AF) is the most common cardiac arrhythmia and its prevalence increases with age. The most dangerous and complex arrhythmias are the result of a phenomenon known as reentry.

Frontiers in Physiology, 2021 BackgroundThere is debate whether human atrial fibrillation is driven by focal drivers or multiwavelet reentry. We propose that the changing activation sequences surrounding a focal driver can at times self-sustain in the absence of that driver. Further,

Alternans amplification following a two-stimulations protocol in a one-dimensional cardiac ionic model of reentry: from annihilation to double-wave quasiperiodic reentry [PDF]
arXiv, 2003 Electrical pacing is a common procedure that is used in both experimental and clinical settings for studying and/or annihilating anatomical reentry. In a recent study [Comtois and Vinet, Chaos 12, 903 (2002)], new ways to terminate the one-dimensional reentry using a simple protocol consisting of only two stimulations were discovered.

Geometric analysis on the unidirectionality of the pulmonary veins for atrial reentry [PDF]
arXiv, 2013 It is widely believed that the pulmonary veins (PVs) of the atrium play the central role in the generation of atrial reentry leading to atrial fibrillation, but its mechanism has not been analytically explained. In order to improve the current clinical procedures for atrial reentry by understanding its mechanism, geometrical analysis is proposed on the
