متن کاملmanipulation in dubbing and subtitling
پژوهش حاضر در چارچوب مکتب دستکاری قرار گرفت و با استفاده از تقسیم بندی دوکات (2007) از شیوه های دستکاری، به دنبال یافتن پاسخ برای پرسش های زیر بود: 1-رایج ترین شیوه دستکاری در دوبله فیلم ها کدام است؟ 2-رایج ترین شیوه دستکاری در زیرنویس فیلم ها کدام است؟ 3-دستکاری در دوبله فیلم ها رایج تر است یا در زیرنویس آن ها؟ این پژوهش از نوع تحقیقات توصیفی- مقایسه ای و پیکره ای می باشد. پیکره تحقیق شا...
Active control of oscillatory thermocapillary convection.
Active control of oscillatory thermocapillary flow was applied in an open cylindrical container filled with silicone oil. Thermocapillary convection was driven by imposing a radial temperature gradient on a flat free surface. The control was realized by locally heating the surface at a single position using the local temperature signal at a different position fed back through a simple algorithm...
متن کاملTrapping and manipulation of microparticles using laser-induced convection currents and photophoresis.
In this work we demonstrate optical trapping and manipulation of microparticles suspended in water due to laser-induced convection currents. Convection currents are generated due to laser light absorption in an hydrogenated amorphous silicon (a:Si-H) thin film. The particles are dragged towards the beam's center by the convection currents (Stokes drag force) allowing trapping with powers as low...
متن کاملBifurcation analysis of the thermocapillary convection in cylindrical liquid bridges
We consider the instability of the steady, axisymmetric thermocapillary convection in cylindrical liquid bridges. Finite-difference method is applied to compute the steady axisymmetric basic solutions, and to examine their linear instability to three-dimensional modal perturbations. The numerical results show that for liquid bridges of O(1) aspect ratio Γ (=length/radius) the first instability ...
