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 ...
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 ...
Studying on the small molecule diffusion into hydrogels: a fluorescence study
(Amer Inst Physics, 2007)
In situ steady state fluorescence experiments (SSF) were reported during the diffusion of water molecules into PAAm in gels at various temperatures. The fluorescence emission intensities, Ip increased continuously as water ...
On complex solutions of the eikonal equation
(IEEE, 2007)
In this paper a new approach of complex rays in an inhomogeneous medium is presented. Complex rays are complex solutions of the eikonal equation, the main equation of the geometical optics. It is shown that solving the ...
