The problem of heat transfer to pulsatile flow of a two-phase fluid-particle system contained in a channel bounded by two infinitely long rigid impervious parallel walls has been studied in this paper. The solutions for the steady and the fluctuating temperature distributions are obtained. The rates of heat transfer at the walls are also calculated. The results are discussed numerically with gr...

A two-phase procedure, based on biosignal recordings, is applied in an attempt to classify the emotion valence content in human-agent interactions. In the first phase, participants are exposed to a sample of pictures with known valence values (taken from IAPS) and classifiers are trained on the physiological data recorded. During the second phase, biosignals are recorded for each participant wh...

Counting is central to ecological studies and conservation research in ornithology. This article examines the present status of counting birds for various purposes in India. Though there is general awareness about proper counting techniques, as evidenced by the variety of methods employed by field biologists, reliability estimates are not available for most studies. Counts that employ large set...

This paper presents a general overview of ow in deformable porous media with emphasis on melt extraction processes beneath mid-ocean ridges. Using a series of simple model problems, we show that the equations governing magma migration have two fundamentally different modes of behaviour. Compressible two-phase ow governs the separation of melt from the solid and forms a non-linear wave equation ...

This paper presents our work on developing parallel computational methods for two-phase flow on modern parallel computers, where techniques for linear solvers and nonlinear methods are studied and the standard and inexact Newton methods are investigated. A multi-stage preconditioner for two-phase flow is applied and advanced matrix processing strategies are studied. A local reordering method is...
