This quantitative research, carried out at the military environment at the Defense Language Institute investigated whether learning approaches could predict learners' language proficiency and learners' attitude towards technology-enhanced language learning (TELL). In addition, it also examined whether learners' demographic factors, such as age, educational backgrounds, prior experience in foreign language learning and in TELL as well as their ability to use PC and the World Wide Web could predict the above mentioned language proficiency and attitude.

Until recently, semiconductor light-emitting diodes (LEDs) were used mainly as simple indicator lamps in electronics and toys. Now, they have begun to replace bulbs in many applications, particularly those requiring durability, compactness, cool operation and/or directionality. This book explores the principles, preparation, and applications of luminescent materials for solid state lighting. The authors focus on an important class of nitride phosphors that are being heavily researched and commercially utilized in these types of applications. They address the design principles, synthesis,...

The finite difference method (FDM) hasbeen used tosolve differential equation systems for centuries. The FDM works well for problems of simple geometry and was widely used before the invention of the much more efficient, robust finite element method (FEM). FEM is now widely used in handling problems with complex geometry. Currently, we are using and developing even more powerful numerical techniques aiming to obtain more accurate approximate solutions in a more convenient manner for even more complex systems. The meshfree or meshless method is one such phenomenal development in the past...
