Along with the continued search for advanced TE materials, the concept of FGM offers a strategy of gradual improvement of device performance.
The target of advanced techniques of materials preparation is to manufacture materials with controlled gradients in the TE properties which ensure optimum TE operation of a device.
One of the main points of this work consists in having shown that this comprehensive engineering information covers a case accurately describing a real system which is very close to the optimum of achievable performance.

Prediction and Measurement of Lamb Wave from Debondings at Structural Features in Composite Laminates Ching-Tai Ng1,a, Martin Veidt 2,b 1School of Civil, Environment & Mining Engineering, The University of Adelaide, Adelaide, South Australia, 5005, Australia 2School of Mechanical and Mining Engineering, The University of Queensland, Brisbane, Queensland, 4072, Australia aalex.ng@adelaide.edu.au (corresponding author), bm.veidt@uq.edu.au Keywords: Debonding, Lamb wave, scattering, finite element, composite laminates Abstract.
Introduction Cost effective and reliable safety diagnosis of engineering structures is a difficult task as the structures usually contains complex structural system.
In recent years composite materials (e.g. composite laminates) have been widely employed as primary structural components in different areas of engineering, such as civil and aerospace engineering, due to their high specific stiffness and light weight characteristics.
Composite laminates consist a number of fibrous composite material layers to provide required engineering properties.

The processing alterations to overcome transition problems lead to advances in understanding of steel metallurgy over the period 1860-1920.
The extensive capabilities of WI gave rise to a revolution of mechanical engineering into an era when machinery was built entirely of iron.
Rolling technology was advanced rapidly through 2-high, 3-high, 4-high, reversing and continuous types with innovations conceived, brought to plant effectiveness and transferred with improvements [5,7,14,20].

Nowadays advanced new ceramic materials, involving Al2O3, ZrO2, SiC, Si3N4, AlN require the use of some amounts of polymeric organic additives playing a similar role to clay-like raw materials [1].

Considering this requirement, many countries, especially those most advanced have adopted new structures in the format of Science and Technology (S&T) Observatory which aim to a set of actions capable enough for collecting, processing and disseminating information and knowledge with the intent of decisions making through a network of elements involved in the S&T management process [1, 2].
For Gusmão [5], some basic missions for an S&T observatory should be considered, such as: (i) conception, construction and permanent updating of a database (domestic and international sources); (ii) production and dissemination of science and technology indicators (inputs and outputs); (iii) contributions in the field of strategic planning and also in the evaluation of government programs and actions; (iv) promotion of sectoral studies; (v) training actions; (vi) forum for discussion and debate on the conduction of national science policy and its instruments.
Findings on Institutional Arrangements for S&T Observatories In Brazil, despite significant advances and efforts by means of a number of initiatives to create local and national observatories, such as the proposed creation of an observatory in the state of Pará and a national observatory within the scope of the CGEE, however, there is still, actually, not a national structure capable of performing activities inherent to a scientific and technological observatory in a consistent, reliable manner which is articulated with different agents.
ABMTENC – the Brazilian Association for Non-Conventional Materials and Technologies was founded in 1996, at the Pontifical Catholic University of Rio de Janeiro – PUC-Rio, integrating scientists, engineers, architects and many other professionals dedicated to the study and development of the science of non-conventional materials and technologies [22].
