This paper investigates the origin of flow-induced instabilities and their sensitivities in a flow over rotationally flexible circular cylinder with rigid splitter plate. A linear stability sensitivity problem is formulated Eulerian frame by considering geometric nonlinearity arising from rotational motion which not present stationary or purely translating methodology. needs careful consistent ...

this paper presents a model of a catchment area in northwest of iran. the researchers have studied ajichai basin which is located in the east part of orumiyeh lake, located at the longitude of 47 52’ e to 45 32’ e and the latitude of 37 26’ n to 38 30’ n. the researchers have chosen the data from tabriz upper air station which is the only one in the area. the research data are seven instability...

a palatal defect may result from surgical resection, and its consequences could include difficulty in speech and nasal regurgitation of food and liquids. an obturator combined to speech aid prosthesis can improve nasal emission during speech,  and  assist  in  preventing  nasal  regurgitation  of  food.  this  article presents a clinical report of the reconstruction of palatopharyngeal function...

Context. The recent variability survey of the NGC 3766 cluster revealed a considerable number of periodic variable stars in a region of the Hertzsprung-Russell diagram where no pulsations were expected. This region lies between the instability strips of the δ Scuti and slowly pulsating B (SPB) stars. Moreover, the periods of the new phenomenon, P∼0.1–0.7 d, do not allow us to associate it a pri...

BACKGROUND Currently, a suitable and reliable noninvasive method to evaluate rotational stability in vivo in anterior cruciate ligament-deficient knees, particularly during sports movements, does not exist. We speculated that if there is a rotational instability, the patient would avoid reaching a high pivoting moment during pivoting activities as a defense mechanism, and that the ground reacti...

This paper presents results from axisymmetric simulations of magneto-rotational stellar core collapse to neutron stars in general relativity. These simulations are performed using a new general relativistic numerical code specifically designed to study this astrophysical scenario. The code is an extension of an existing (and thoroughly tested) hydrodynamics code, which has been applied in the r...

Gradient-driven instabilities and the subsequent nonlinear evolution of generated vortices in sheared E X B flows are investigated for magnetized plasmas with and without gravity (magnetic curvature) and magnetic shear by using theory and implicit particle simulations. In the linear eigenmode analysis, the instabilities considered are the Kelvin-Helmholtz (K-H) instability and the resistive int...
