In order to provide efficient interface between web services and components, Online Tutoring Framework for E-learning system using Web Service technology (OTFWS) is introduced to present an E-learning system in a well-organized way. An interface offered here acts as the crossing point for the back end web services and the learning software component model. The proposed web service interface is built based on the back end web service and middleware interactive components. The interface online tutoring environment is the significant contribution in which each student and tutor is presented with a unique code. Using the unique code, the student can communicate with the tutors regarding the course which he desires to choose. Based on the students¿ necessities, the interface will provide an E-learning system with interactive services and materials.

Microwave assisted extraction (MAE) is a conventional technique for the extraction of active components from medicinal plants, using microwave energy with frequency range from 300 MHz to 300 GHz to heat solvents containing samples, thereby partitioning analytes from a sample matrix into the solvent. The transfer of energy in MAE occurs via the mechanisms of ionic conduction and dipole rotation that may occur simultaneously. The mechanism of ionic conduction relates to the migration of ions through a solution, causing a homogeneous heat in the media due to the resistance of the solvent to the ionic migration when applying electromagnetic waves. Dipole rotation makes reference to the reorientation of the molecules in the direction of the electric field, causing thermal agitation once the electromagnetic waves are removed due to the agitation of the molecules that go back to a disordered state. The moisture content of the sample matrix is the main target of microwave heating during MAE. As the water evaporates, the intracellular pressure increases, breaking the cell walls and increasing the leaching of high-value compounds.

This book presents an evaluation methodology to design future FPGA fabrics incorporating hard embedded blocks (HEBs) to accelerate applications. The book also explains how the respective HEBs are designed and how hardware implementation of the application is done using these HEBs.
