In order to satisfy stringent requirements for precision control and lightweight miniaturization, smart materials such as shape memory alloys, piezoceramics, electroorheological fluids and magnetorheological fluids are frequently adopted for controllable structures.
Piezoelectric materials can be effectively used for active vibration control with fast response and easy implementation [1- 3].
Mayhan combined intelligent control and smart materials to produce an adaptive and robust controller to dampen the fundamental vibration mode of the system in the presence of modeling uncertainties [7].

Nano-ZnFe2O4 is a traditional ferrite material, which is widely used in electro-magnetic and luminescent materials.
With the rapid development of nano-materials and nano-technology, additional kinds of nano-particle materials have been discovered, contributing to the multi-functionality of nano-composite materials [6].

Dielectric properties of ββββ-SiAlON at high temperature using perturbation method Young-Hoon Seong a, Ha Neul Kim b, and Do Kyung Kim c Department of Materials Science and Engineering, Korea Advanced Institute of Science and Technology (KAIST), 335 Gwahangno Yuseong-gu, Daejeon, 305-701, Korea a eric_1999@kaist.ac.kr, bjoeperry@kaist.ac.kr, cdkkim@kaist.ac.kr Keywords: Dielectric constant, tangent loss, SiAlON, perturbation method Abstract. β-SiAlON with various z-values (z = 0.5~4.0) were produced by hot pressing.
As a result, it is important that both dielectric constant and tangent loss should be lower than the other microwave window materials [2].
It is also possible, under some circumstance, to predict the dielectric behavior of a mixture of materials from the dielectric properties of the individual components and this can be of benefit when designing materials for microwave processing.
Experimental Procedure Commercially available α-Si3N4 (UBE-SN-E10, Ube chemical, Japan), Al2O3 (AKP-50, Sumimoto, Japan) and AlN (grade F, Tokuyama, Japan) were used in the preparation of the materials. β-Si6zAlzOzN8-z with various z-values (0.5, 1.0, 2.0, 3.0, and 4.0) was prepared in five different batches of powders.
