Mixed-method validation of pedagogical concepts for an intercultural online learning environment: a case study
(Assoc Computing Machinery, 2007)
The rise of social software poses the challenges to the design and evaluation of a pedagogically sound online learning environment (OLE). Our OLE addresses these challenges by the integration of three pedagogical concepts ...
Reversible film formation from nano-sized PNIPAM particles below glass transition
(Springer-Verlag, 2007-01)
Reversible film formation process from nano-sized Poly(N-isopropylacrylamide) (PNIPAM) microgel particles were studied during heating-cooling cycles at various rates. Photon transmission technique was used and transmitted ...
Comparison of evolutionary techniques for Value-at-Risk calculation
(Springer-Verlag Berlin, 2007)
The Value-at-Risk (VaR) approach has been used for measuring and controlling the market risks in financial institutions. Studies show that the t-distribution is more suited to representing the financial asset returns in ...
Estimation of microstretch elastic moduli by the use of vibrational data
(Springer, 2007)
In the present work, a nonlinear wave theory is used for the estimation of the material properties of a "microstretch" medium. For this purpose a thin plate is considered and triplicate Chebyshev polynomial series are used ...
Nonlinear waves in fluid-filled elastic tubes: A model to large arteries
(Springer, 2007)
In the present work, by treating the arteries as a prestressed thin walled elastic tube of variable radius and the blood as an incompressible inviscid fluid, we have studied the propagation of weakly nonlinear waves in ...
Drying of PAAm hydrogels at various temperatures: A fluorescence study
(Taylor & Francis Group, 2007-05)
The steady-state fluorescence (SSF) technique was employed for studying the drying of polyacrylamide (PAAm) hydrogels. Disc-shaped hydrogels were prepared by free-radical crosslinking copolymerization of acrylamide (AAm) ...
Study on swelling of hydrogels (PAAm) at various temperatures by using fluorescence technique
(Springer US, 2007-10)
Steady-state fluorescence (SSF) technique was employed for studying swelling of polyacrylamide (PAAm) hydrogels. Disc-shaped gels were prepared by free-radical crosslinking copolymerization of acrylamide (AAm) with N, N'- ...
Small molecule sorption and desorption in and out of iota-carrageenan gels
(Taylor & Francis Group, 2007-08)
Small molecule sorption and desorption in and out of Iota-Carrageenan was studied by using steady-state fluorescence (SSF) technique. Pyranine dissolved in water used as fluorescence probe. Fluorescence emission intensity, ...
Transmission increase upon switching of VO2 thin films on microstructured surfaces
(American Institute of Physics, 2007-08-27)
The authors compare transmission measurements of near-infrared light through VO2 thin films on smooth substrates and on ordered arrays of silica microspheres. When the samples are heated above the critical temperature for ...
The modified reductive perturbation method as applied to the Boussinesq equation
(Verlag Z Naturforsch, 2007-08)
In this work, we extended the application of "the modified reductive perturbation method" to long water waves and obtained the governing equations of Korteweg-de Vries (KdV) hierarchy. Seeking localized travelling wave ...
