In this work, nanosized hydroxyapatite (HA) powder was synthesized via mechanochemical method by a dry mixture of calcium hydroxide Ca(OH)2 and di-ammonium hydrogen phosphate (NH4)2HPO4 powders. The effect of mechanochemical process on powder properties was investigated. Three rotation speeds of 170 rpm, 270 rpm and 370 rpm were chose with 15 hours

This chapter discusses the direct identification of bending rigidities of a thin anisotropic composite plate. The simultaneous identification of constitutive parameters from heterogeneous strain fields is an important issue in the experimental solid mechanics community.The idea is to determine the unknown parameters from a single test giving a uniq

This book intends to present the application of FMEA method on Three-Way Catalytic Converter (TWC) system. Catalytic converter of auto-exhaust emission is one of the most successful applications of heterogeneous catalysis, both in commercial and environmental point of view. Catalytic converter has been proved critical to controlling pollution of CO

This chapter discusses the important issue of experimental noise simulation in the formulation of piecewise virtual fields method for the characterization of thin composite plate. In actual practice, the full field data captured through an optical dive on the surface of a specimen is always prone to some noise effect. In order to accurately identif

This chapter discusses reciprocity gap method that makes use of full filed data. In this method, full field displacement data is measured at the specimen boundary. For the case of static loading, displacement-force boundary data is measured and using principle of virtual work, a reciprocity gap functional is reconstructed to give the interior and w

This chapter discusses constitutive equation gap method used for identification of materials constitutive parameters. It involves a comparison of given stress field and displacement field to a computed stress field generated by using an initial set of materials constitutive model. This method is based on the gap estimation and minimization that is

This chapter discusses the equilibrium gap method that utilizes full field data measured over a surface. The method has been shown to give promising results for identification of elastic constitutive properties. Also, the method has been applied to the case of a damaged specimen. Initial trial values of unknown data is given as input and then the g

This paper focuses on the contractual mechanisms that will help to achieve a fair allocation of risk between operators and contractors in the oil and gas projects. Companies that are actively dealing with a wide range of activities which engage volatile hydrocarbons are exposed to substantial risks and liabilities. In this regard, most of the petro

The aspiration of Malaysian education system as mentioned in the Malaysia Education Blueprint 2013-2025 is to produce students who are highly critical and creative. Since teaching for higher order thinking was made explicit since 1989, a systematic evaluation of the adequacy and pitfalls of teaching for thinking programs was not done extensively. I
