Wall effect in laminar flow of non-Newtonian fluid through a packed bed
(2000)Experiments were conducted on laminar flow of non-Newtonian fluid through a packed bed of low column to packing particle diameter ratio (3.8) to elucidate the wall effect on pressure drop and mass flux. Carboxy methyl ... -
Wave interaction and hot electron effects in semiconductors and plasmas

Waveguide polarizer based on resonant tunneling
(1991)A novel and highly efficient waveguide polarizer which is based on the phenomenon of resonant tunneling is proposed. Designs for both transverse-electric (TE) and transverse-magnetic (TM) pass polarizers based on this ... -
Wavelength division multiplexing of phase modulated solitons
(1992)The simultaneous propagation of N phase modulated bright solitons at N different wavelengths in a single mode optical fiber is considered. The conditions necessary for such wavelength multiplexed operation in a lossless ... -
Wavelength-division multiplexing isolation filter using concatenated chirped long period gratings
(2001)We propose the use of concatenated chirped long period gratings as an efficient wavelength-division multiplexing (WDM) isolation filter. The proposed filter not only works in the transmission mode but also has almost ... -
Wavelet filtering applied to time-average digital speckle pattern interferometry fringes
(2001)In this paper we are presenting a filtering scheme using Symlet wavelet to remove the speckle noise from the time-averaged digital speckle pattern interferometry fringes. To demonstrate the potential of Symlet wavelet ... -

Wear data analysis of friction materials to investigate the simultaneous influence of operating parameters and compositions
(2004)The present paper deals with the wear data analysis of friction composites where, the nature and the concentration of the abrasives were varied systematically in steps of 2%. The abrasives selected were; SiC, SiO2, ZrO2 ... -
Wear of cryo-treated engineering polymers and composites
(1999)Polymers and composites are extensively used in wear situations dominated by various types of abrasive mechanisms. Incorporation of,heat treatment and surface engineering by various chemical and physical techniques have ...
