Emergence of Warm Inflation in Curved Space‐Time between Accelerating Branes
Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 It appears that having our own brane to somehow interact with other branes could give rise to quite an interesting system and that interaction could lead to some observable effects. We consider the question of whether or not these signatures of interaction between the branes can be observed. To answer this question, we investigate the effect induced by

Modeling of the Tail Slap for an Underwater Projectile within Supercavitation
Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019 Detailed process of the tail slap for an underwater projectile in supercavitation is studied in this paper. Firstly, the horizontal equation of motion for the projectile and a dynamic model of the projectile’s tail slap are introduced through a mathematical derivation, including a simple harmonic motion model of the projectile within the ...

Statistical azimuthal structuring of the substorm onset arc: Implications for the onset mechanism
Geophysical Research Letters, Volume 44, Issue 5, Page 2078-2087, 16 March 2017., 2017 Abstract The onset of an auroral substorm is generally thought to occur on a quiet, homogeneous auroral arc. We present a statistical study of independently selected substorm onset arcs and find that over 90% of the arcs studied have resolvable characteristic spatial scales in the form of auroral beads.

Analysis of the Conformally Flat Approximation for Binary Neutron Star Initial Conditions
Advances in Astronomy, Volume 2017, Issue 1, 2017., 2017 The spatially conformally flat approximation (CFA) is a viable method to deduce initial conditions for the subsequent evolution of binary neutron stars employing the full Einstein equations. Here we analyze the viability of the CFA for the general relativistic hydrodynamic initial conditions of binary neutron stars.

Vacuum Condensate, Geometric Phase, Unruh Effect, and Temperature Measurement
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 In our previous work the possibility to use the Aharonov‐Anandan invariant as a tool in the analysis of disparate systems has been shown, including Hawking and Unruh effects, as well as graphene physics and thermal states. We show that the vacuum condensation, characterizing such systems, is also related with geometric phases and we analyze the ...

Augmenting the Structures in a Swirling Flame via Diffusive Injection
Journal of Combustion, Volume 2014, Issue 1, 2014., 2014 Small scale experimentation using particle image velocimetry investigated the effect of the diffusive injection of methane, air, and carbon dioxide on the coherent structures in a swirling flame. The interaction between the high momentum flow region (HMFR) and central recirculation zone (CRZ) of the flame is a potential cause of combustion induced ...

Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014 This study contributes towards describing the nature of cycle‐by‐cycle variability in homogeneous charge compression ignition (HCCI) engines. Experimental measurements were performed using a single cylinder research engine operated in the negative valve overlap (NVO) mode and fuelled with direct gasoline injection. Both stoichiometric and lean mixtures

Flow Measurements Using Particle Image Velocimetry in the Ultracompact Combustor
International Journal of Aerospace Engineering, Volume 2012, Issue 1, 2012., 2012 The potential for the ultracompact combustor (UCC) lie in future research to reduced fuel consumption and improved engine performance. Velocity measurements performed on the UCC test rig at the Air Force Institute of Technology revealed flow patterns and time‐averaged turbulence statistics for data taken burning hydrogen fuel in a straight and a curved

Revealing Two Operation Modes of Perovskite Light‐Emitting Diodes Through Overshoot Pulses
Advanced Photonics Research, Volume 7, Issue 1, January 2026.Short, high‐intensity overshoot pulses (OSPs) may be generated by perovskite light‐emitting diodes (PeLEDs) depending on electrical pump pulse parameters, offset and afterpulse voltages. OSPs reveal two PeLED operation modes: the recombination mode, favorable for the conventional EL but preventing OSPs, and the accumulation mode, enabling the formation

Advances in Condensed Matter Physics, Volume 2011, Issue 1, 2011., 2011 The emerging structures in spinodal dewetting of thin nano films and spinodal decomposition of binary mixtures are found to be similar with certain differences attributed to the nonlinearities inherent in the wetting forces. This paper deals with the technological aspects of the spinodal processes by giving a brief account of the theory and to ...
