hydroxyapatite is a biocompatible ceramic and reinforcement for bone implantations. seva/hap composite content hap filler with difference particle sizes were designed. mechanical tests like tensile modulus, uts, strain at break and biodegradation were investigated. results illustrated much increase tensile modulus of composites content hap nano powders ratio to micro powders. also uts analysis ...

Let $\mathcal A$ denote a set of positive integers, and let $p(\mathcal A,n)$ the associated partition function. $\beta $ be an odd integer, $P(z)$ polynomial in \mathbb F_2[z]$ order such that $P(0)=1$. J.-L

This paper examines the extent to which the daily movements of three large emerging markets stock indices are predictable. Lagged technical indicators are used as explanatory variables. In the analysis we employed seven classification techniques and assessed the discriminatory power of the classifiers through the area under the receiver operating characteristic (ROC) curve.
