This study examines the influence of instructional design and management style on student achievement and satisfaction in a web-based distance learning environment. From the literature review, two major instructional design and management styles in web-based distance education were conceptualized as structure and interpersonal interaction. To investigate the differences on learning output varia...

Classical speech synthesis systems either concatenate diphone-like tabulated pattems or reconstmct speech parameters according to pre-defmed mles. Both techniques show drawbacks : the fonner lacks flexibility while the lauer is highly time-consuming_ to built. We propose an intennediate technique using structured segments : segmental units are still resorted to, but they are automatically analy...

OBJECTIVE Due to the capacity of the amniotic membrane (Am) to support re-epithelisation and inhibit scar formation, Am has a potential to become a considerable asset for reconstructive urology i.e., reconstruction of ureters and urethrae. The application of Am in reconstructive urology is limited due to a poor mechanical characteristic. Am reinforcement with electrospun nanofibers offers a new...

in this paper, a new stage structured prey-predator model with linear functional response is proposed and studied. the stages for prey have been considered. the proposed mathematical model consists of three nonlinear ordinary differential equations to describe the interaction among juvenile prey, adult prey and predator populations. the model is analyzed by using linear stability analysis to ob...

Modern manufacturing systems seem to be shifting from mass production to mass customisation, which means that systems must be able to manage changes in customer demands and requirements, new technology as well as environmental demands. This in turn leads to an increase in product variants that need to be assembled. To handle this issue, well designed and presented information is vital for assem...

The purpose of this paper is to extend the Green-Naghdi-Rivlin balance of energy method to continua with microstructure. The key idea is to replace the group of Galilean transformations with the group of diffeomorphisms of the ambient space. A key advantage is that one obtains in a natural way all the needed balance laws on both the macro and micro levels along with two Doyle-Erickson formulas....

Optical 3D measurement is meaningful in numerous industrial applications. In various cases, the objects to be measured moreover contain only sparse or even no texture. Predestinated examples are agricultural products like peeled potato tubers as well as industrial repetition parts made of plastic or ceramic, such as housing parts or ceramic bottles. These parts are often conveyed in a wobbling ...
