In light of the chance that the plate will be saved by a sudden gust of hot air, what should we say about the truth conditions of the ordinary conditional (1b)? Some theories predict that (1b) is true. For instance, Lewis 1973b says that the plate being saved by friendly air currents is a remarkable low-probability event, and that worlds where such events happen are farther away than worlds whe...

evaporation of micro-liter drops from solid surfaces at room condition is mainly governed by diffusion. therefore, there should be no difference between evaporation rate of sessile and pendant drops. however, some studies indicate a difference and explain the difference using buoyancy. the objective here is to reconcile the inconsistency in the literature. for that, first, by comparing two iden...

In this paper, we present a technique for the deposition of inks, toners, organic polymers, fuels, small solid particles, biological and chemical fluids, using a fluid ejector. The ejector design is based on a flextensional transducer that excites the axisymmetric resonant modes of a clamped circular plate. It is constructed by depositing a thin piezoelectric annular plate onto a thin, edge cla...

The present work deals on the experimental investigation on the heat transfer and pressure drop characteristics of CNT coating on a stainless steel substrate in a rectangular macro channel with water as the working fluid. The experiments were conducted under both laminar and turbulent flow conditions with Reynolds number varying from 500-2600. The experimental results using an uncoated stainles...

Ballistic simulation of the spray sprinkler for self-propelled irrigation machines requires the incorporation of the effect of the jet impact with the deflecting plate. The kinetic energy losses produced by the jet impact with the spray plate were experimentally characterized for different nozzle sizes and two working pressures for fixed spray plate sprinklers (FSPS). A technique of low speed p...

Stress drop is a fundamental parameter of earthquakes, but it is difficult to obtain reliable stress drop estimates for most earthquakes. Static stress drop estimates require knowledge of the seismic moment and fault area. Dynamic stress drop estimates are based entirely upon the observed source time functions. Based on analytical formulas that I derive for the crack and slip-pulse rupture mode...
