Students' perceptions of institutional and instructor based techniques for dealing with academic dishonesty
(Proceedings of the 32nd Frontiers in Educational Conference, Boston, MA, 2002-11)
Research suggests that a large percentage of engineering students engage in some form of academic dishonesty. To investigate this very serious concern, the authors have undertaken a research project on the Perceptions and ...
Corrected HorvÁth-Kawazoe equations for pore-size distribution
(Wiley Subscription Services, Inc., A Wiley Company, 2000-04)
The HorvÁth-Kawazoe (HK) model is a widely used method for determining pore-size distribution in a microporous material from a single adsorption isotherm. The original model, however, suffers from conceptual flaws. The ...
Biomass plug development and propagation in porous media
(John Wiley & Sons, Inc., 2001-02-05)
Exopolymer-producing bacteria can be used to modify soil profiles for enhanced oil recovery or bioremediation. Understanding the mechanisms associated with biomass plug development and propagation is needed for successful ...
LETTER TO THE EDITOR: Efficient measurement of the percolation threshold for fully penetrable discs
(IOP Publishing Ltd, 2000-10-27)
We study the percolation threshold for fully penetrable discs by measuring the average location of the frontier for a statistically inhomogeneous distribution of fully penetrable discs. We use two different algorithms ...
Transpiration-based micropump for delivering continuous ultra-low flow rates
(IOP Publishing Ltd, 2003-03-01)
In this paper we describe the design, construction and operation of a micropump that delivers continuous, ultra-low flow velocities at ∼100 μm s−1. The pumping concept is based on the commonly observed phenomenon of ...
Molybdenum carbide catalysts for water–gas shift
(Kluwer Academic Publishers-Plenum Publishers; Kluwer Academic Publishers ; Springer Science+Business Media, 2000-12)
Molybdenum carbide (Mo 2 C) was demonstrated to be highly active for the water–gas shift of a synthetic steam reformer exhaust stream. This catalyst was more active than a commercial Cu–Zn–Al shift catalyst under the ...
Effects of surface morphologies on flow behavior in karst condjuits
(Proceedings of the 15th Int. Congress of Speleology, 2009)
Mathematical modeling of drop mixing in a slit-type microchannel
(IOP Publishing Ltd, 2001-09-01)
Fast solute mixing can be achieved in a microchannel by rapid unidirectional displacement of a discrete liquid drop. The recirculation streamlines created within the liquid during the drop's motion cause the solute to ...
Self-contained actuation of phase-change pistons in microchannels
(IOP Publishing Ltd, 2006-04-01)
An inchworm-like self-contained actuation mechanism for phase-change pistons using a movable thermopneumatic air chamber has been demonstrated. Two phase-change pistons that enclose an air pocket between them have been ...
