Abstract In this paper, the solution to a coupled flow problem for micropolar medium undergoing structural changes is presented.

Tracking of an absolutely continuous reference signal (assumed bounded with essentially bounded derivative) is considered in the context of a class of nonlinear, single-input, single-output, dynamical systems modelled by functional differential equations satisfying certain structural hypotheses (which, interpreted in the particular case of linear systems, translate into assumptions – ubiquitous...

Funnels are open magnetic structures connecting the chromosphere with the solar corona (Axford & McKenzie 1997; Marsch & Tu 1997; Hackenberg et al. 1999). We investigate the stationary plasma flow out of funnels with a flux-tube model. The funnel area function is derived from an analytical 2-D magnetic field model. Since the funnel height is only approximately 15 Mm, the area function for great...

E-learning is the application of information technology in the teaching and learning process. This paper presents the Funnel model as a solution for the problems of implementation of E-learning in tertiary education institutions. While existing models such as TAM, theory-based E-learning and pedagogical model have been used over time, they generally been found to be inadequate because of their ...

Studies of intermolecular energy landscapes are important for understanding protein association and adequate modeling of protein interactions. Landscape representation at different resolutions can be used for the refinement of docking predictions and detection of macro characteristics, like the binding funnel. A representative set of protein-protein complexes was used to systematically map the ...

Lindgren funnel traps baited with aggregation pheromones are widely used to monitor and manage populations of economically important bark beetles (Coleoptera: Scolytidae). This study was designed to advance our understanding of how funnel trap catches assess bark beetle communities and relative abundance of individual species. In the second year (2005) of a 3-yr study of the bark beetle communi...
