Unitarity meets channel-duality for rolling/decaying D-branes [PDF]
Journal of High Energy Physics, 2006 Investigations for decay of unstable D-brane and rolling of accelerated D-brane dynamics have revealed that various proposed prescriptions give different result for spectral amplitudes and observables. Here, we study them with particular attention to unitarity and open-closed channel duality. From "ab initio" derivation in the open string channel, both

Study on Roll Motion Characteristics of a Rectangular Floating Structure in Regular Waves [PDF]
한국해양공학회지, 2019 This study focused on the roll motion characteristics of a two-dimensional (2D) rectangular floating structure under regular beam sea conditions. An experiment was conducted in a 2D wave tank for a roll free decay test in calm water and the roll motion ...

Experimental Study on Estimation of Roll Damping for Various Midship Sections [PDF]
한국해양공학회지, 2019 The magnitude of the roll motion of a floating structure depends on the roll damping acting on the body. In other words, the roll damping of a floating structure must be accurately obtained in order to precisely evaluate the roll motion.

Mechanistic driving force for martensite decay in rolling contact fatigue
Tribology International, 2023 Martensite decay due to large scale microstructural alterations is the main fatigue process which occurs during extensive rolling contact fatigue in bearing applications. Despite its practical and scientific importance, the full description of the controlling phenomena is still incomplete.

Analisa Perubahan Panjang Model FPU Barge Terhadap Koefisien Linier dan Kuadratik Roll Damping
Kapal, 2018 Roll damping sangat berperan penting pada maksimum roll terutama pada daerah resonansi disekitar roll natural period. Dalam prediksi gerak roll, prediksi roll damping dilakukan dengan metode difraksi radiasi yang menambahkan viscous roll damping dari ...

Frequency-Domain Analysis of Linear Time-Periodic Systems [PDF]
, 2004 In this paper, we study convergence of truncated representations of the frequency-response operator of a linear time-periodic system. The frequency-response operator is frequently called the harmonic transfer function. We introduce the concepts of input,

Enigmatic surface rolls of the Ellesmere Ice Shelf
Journal of Glaciology, 2022 The once-contiguous Ellesmere Ice Shelf, first reported in writing by European explorers in 1876, and now almost completely disintegrated, has rolling, wave-like surface topography, the origin of which we investigate using a viscous buckling instability ...

Evolution of fNL to the adiabatic limit [PDF]
, 2011 We study inflationary perturbations in multiple-field models, for which zeta typically evolves until all isocurvature modes decay--the "adiabatic limit". We use numerical methods to explore the sensitivity of the nonlinear parameter fNL to the process by
