The focus of this study is to compare the experimental measured thermal behavior of traditional and waste materials in residential buildings with simulation results.
It means that waste materials in southern walls could decrease 0.9% to 4.1% of indoor temperature compared with traditional materials.
This validation is considered an initial step to study the effect of using waste materials in the residential buildings envelope, which is applied in walls brick [[] Senthil Kumar, Study of Properties of Geopolymer Eco Bricks, Journal of Civil Engineering 5 (2015), pp. 139-148. ,[] Aeslina Abdul Kadir, Noor Amira Sarani, An Overview of Wastes Recycling in Fired Clay Bricks, International Journal of Integrated Engineering 4 (2012) pp. 53-69. ], and is also considered as a method to improve energy efficiency instead of using traditional materials.
To simulate the thermal conditions, the materials were defined in Design Builder as the same materials implemented in the experimental model, Fig. 3 shows the section of rooms elements in Design Builder a) The walls section of room0 (RO), b) The southern wall section of room1 (R1), c) the roof section of room0 (R0) and room1 (R1).
It is concluded that Design-Builder is a suitable simulation software to predict indoor temperature, which is depending on accurate input data for building such as the used materials U value and type of ventilation.

Hysteresis hinders the effective use of piezoelectric smart materials in sensors and actuators.
Introduction Ionic polymer-metal composite (IPMC) as a piezoelectric smart materials is discovered by Oguro and his co-workers [1].
However like other smart materials, IPMC as a sort of piezoelectric actuator has the disadvantage of hysteresis behaviors [2].

The present paper comprehensively reviews non contact nondestructive testing (NDT) methods in use around the world for the solid materials.
(4) This kind of detection is only applicable to metal materials.
The laser ultrasonic detection technology has been applied very well in metal, composite materials and pottery.
However, ultrasonic detection frequency is relatively low and only suitable for detecting part of the materials.
