In this work, we present a characterization of phase configuration in water-saturated sintered glass bead samples after oil injection, through the analysis time-dependent diffusion coefficients obtained from sets one-dimensional pulsed field gradient nuclear magnetic resonance (PFG NMR) measurements, pre and post drainage. Estimates samples' surface-to-volume ratio permeability drainage PFG mea...

Abstmct--We consider the convergence properties of certain algorithms arising in storhastie, discrete-time, adaptive estimation problems and operating in random environments of engineering d@hnce. We demonstrate that the algorithms operating mder ideal conditions are d e s d i l e by homogeneous time-varying linear difference equations with dependent random coefficients, while in praclical use,...

Functional magnetic resonance imaging is routinely used to localize brain function, with multiple brain scans averaged together to reveal activation volumes. In this study, we examine the seldom-studied effect of multiple scan averaging on the extent of activation volume. Using restricted visual field stimulation, we obtained a large number of scan repetitions and analyzed changes in activation...

Many sports events, facilities, and franchises are subsidized either directly or indirectly by investments from public sector funds. The scarcity of tax dollars has led to growing public scrutiny of their allocation; in this environment there is likely to be an increased use of economic impact analysis to support public subsidy of these events. Many of these analyses report inaccurate results. ...

Let K denote an algebraically closed field with characteristic 0. Let V denote a vector space over K with finite positive dimension and let A,A denote a tridiagonal pair on V . We make an assumption about this pair. Let q denote a nonzero scalar in K which is not a root of unity. We assume A and A satisfy the q-Serre relations AA − [3]AAA+ [3]AAA −AA = 0, AA− [3]AAA + [3]AAA −AA = 0, where [3] ...

The use of a siphon is drainage method that does not require the external power, and siphons are used extensively in practice. application treatment soft soils has become popular approach recent years. Analyzing change water level multi-well siphoning basis siphons. calculation model established through equivalent transformation. A finite difference to solve model, accuracy verified by comparin...

According to the linear viscoelastic model, the population discrete elements under the vibration working condition of the seed tray of the seeder were assumed as rigid conditions to analyze the collision process. The dynamic characteristics among the population collision process for the vibration process of the seeder were analyzed by tracing the microcosmic motion of each seed. The following c...

The boundary layer flow and heat transfer on a stretched surface moving with prescribed skin friction is studied for permeable surface. The surface temperature is assumed to vary inversely with the vertical direction x for n = -1. The skin friction at the surface scales as (x) at m = 0. The constants m and n are the indices of the power law velocity and temperature exponent respectively. Simila...

In this study, a review and discussion has been made on the research work of heat transfer in manifolds previously done. Since it is difficult to determine the heat transfer coefficients in different areas of a suction or discharge chamber by using conventional methods, the mass transfer analogy -sublimation of naphthalene has been used to develop the heat transfer correlations for the four are...
