an overview of the smart materials. The various types of smart material are also presented in this paper. To get the clear idea about the smart materials‚ its definition and types are explained briefly. Some of the types of these include piezoelectric materials‚ magneto-rheostatic materials‚ electro-rheostatic materials‚ and shape memory alloys piezoelectric‚ Varieties of smart materials already exist‚ and research is being carried out extensively to derive new materials.

SMART MATERIALS 1. Introduction The primary characteristic of a ‘‘smart material’’ is that it has the ability to respond to external stimuli in a technically useful and technically controlled way. The words ‘‘technically useful’’ and ‘‘technically controlled’’ are emphasized since all materials respond to external stimuli of some sort or other (as a simple example‚ all materials respond to temperature by changing their volume)‚ however‚ to be considered a ‘‘smart material’’ the response must

3 Basic manufacturing cost categories: Direct Materials Cost: The materials that go into final product are called raw materials. Direct Labor Cost: The term direct labor is reserved for those labor costs that can be essentially traced to individual units of products. Direct labor is sometime called touch labor‚ since direct labor workers typically touch the product while it is being made. Manufacturing Overhead Cost: Manufacturing overhead‚ the third element of manufacturing cost‚ includes

The Stromboli stratovolcano off the coast of Sicily has erupted continuously for thousands of years‚ giving rise to the termstrombolian eruption. Lava composition Another way of classifying volcanoes is by the composition of material erupted (lava)‚ since this affects the shape of the volcano. Lava can be broadly classified into 4 different

composers. There arose six broad categories of instruments that western musicians today classify as the string‚ woodwind‚ brass‚ percussion‚ keyboard and electronic. Each category incorporates a range of instruments that have created living history through music. Each instrument brings its own tone color to the music and has a variety of other characteristics that set it apart to bring out its own personality. Compositions have been written including all categories of instruments or to single out

This can be done by the use of instructional materials. Instructional materials are meant to stimulate pupils’ interest in the classroom for meaningful learning to take place. They also afford the pupils the opportunity to make use of more of their senses in the process of learning experiences which are not available in the classroom or school environment‚ are “brought” to the classroom for pupils’ attention through the use of instructional materials. For example‚ the use of the map of the world
