Write Tutor

Abstract

The article addresses the technical principles of a new interactive Robotic device, called Write Tutor, and gives an overview of its application. In spite of the various measures and efforts taken in terms of improving literacy rate we still have a major section of the population who are not able to read and write. The Write Tutor, a completely autonomous device can teach children and people of any age group the art of writing. The mechanism is programmed with speech recognition system and makes the user write what he speaks holding his wrist. It also can make you draw pictures in the graphical mode. The Write tutor also has built-in modules to teach reading and writing simultaneously using its on board display. The workspace is designed enabling the user to write on a sheet size varying from a post card to an A4 sheet. Therefore the Write Tutor is a low cost device that can be programmed to teach people in different languages, people who are physically challenged, autistic and dyslexic children and children in elementary schools.

Thermal modelling of the emerging multi-chip packages

“…The analysis of the parameter setting proposed by [5] appeared to us to be less robust, it does not ensure a constant quality of the solution , which is one of our aims. In contrast, we also consider a division of the upper and lower surfaces of the package which provides much more reliable results.…”

“…The creation of a Compact Thermal Model as defined by A. Parthiban which also promotes the use of the genetic algorithms , allowed us to compare Thales methodology to a common approach [5].…”

Unimolecular ligand–initiator dual functional systems (ULIS) for low copper ATRP of vinyl monomers including acrylic/methacrylic acids

“…The control on polymerization was dependent on the structure of ULIS and also the solvent used for polymerization. As the polymerization works well in water as well, 6 we believe that this system is highly adaptable for emulsion polymerization in the conventional manner. The ability to make super absorbent polymers is another attractive feature of this modified process.…”

“…1). 6 Through this modification, we visualized that the polymerization may proceed more homogeneously and the active-dormant cycles of the ATRP process may become intramolecular in nature. Also, the energy barrier for the cleavage of the C-X bond leading to the formation of radicals as well as that of the red-ox process involving Cu I /Cu II transformation can be expected to be different in the case of ULIS as compared to the conventional ATRP process due to its intramolecular nature.…”

“…9 Also, it is possible to directly homo-and copolymerize free carboxylic acid bearing vinyl monomers using ULIS as reported here. For this work we have synthesized many unimolecular ligand-initiator systems (ULIS), 6 three of which are presented here in Fig. 1, namely, SBLI, TALI and TDLI, with different ligand components by employing various synthetic protocols (see the experimental section in ESIw).…”
