Extreme Mass Ratio Binary: Radiation reaction and gravitational waveform [PDF]

, 2005
For a successful detection of gravitational waves by LISA, it is essential to construct theoretical waveforms in a reliable manner. We discuss gravitational waves from an extreme mass ratio binary system which is expected to be a promising target of the ...

Accretion disc dynamics in extreme mass ratio compact binaries [PDF]

, 2007
An analysis is presented of a numerical investigation of the dynamics and geometry of accretion discs in binary systems with mass ratios q < 0.1, applicable to ultra-compact X-ray binaries, AM CVn stars and very short period cataclysmic variables.

Binary mass ratios: system mass not primary mass [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2012
Abstract Binary properties are usually expressed (for good observational reasons) as a function of primary mass. It has been found that the distribution of companion masses – the mass ratio distribution – is different for different primary masses. We argue that system mass is the more fundamental physical parameter to use.

Modelling Rocket System Performance Parameters

Academy Journal of Science and Engineering, 2022
What distinguishes the rocket system from airbreathing engines is that the rocket carries its own propellants, fuel and oxidants.  The modern rocket was originally developed for ballistic missiles.

Considerations on similarity condition of wing deformation in flapping for model and mosquito wings

Journal of Biomechanical Science and Engineering, 2019
In our previous paper, to simulate mosquito flapping flight, experiments were performed using a wing model, which had n-times (n=10) enlarged shape of the mosquito wing and was made of deformable elastic material.

Event Horizon Deformations in Extreme Mass-Ratio Black Hole Mergers [PDF]

, 2011
We study the geometry of the event horizon of a spacetime in which a small compact object plunges into a large Schwarzschild black hole. We first use the Regge-Wheeler and Zerilli formalisms to calculate the metric perturbations induced by this small ...

Maximized Energy Density of RuO2//RuO2 Supercapacitors through Potential Dependence of Specific Capacitance

ChemElectroChem, 2020
In this study, a stepwise cyclic voltammetry approach was proposed to clarify the potential dependence of specific capacitance for reduced graphene oxide and ruthenium oxide electrodes. Based on the relationship between specific capacitance and potential,

Binary black hole merger in the extreme mass ratio limit [PDF]

, 2006
We discuss the transition from quasi-circular inspiral to plunge of a system of two nonrotating black holes of masses $m_1$ and $m_2$ in the extreme mass ratio limit $m_1m_2\ll (m_1+m_2)^2$.
