Natural fiber-reinforced composites are necessary to increase the use of polymer composite technology. This study investigates a specific type bamboo species named Gigantochloa Scortechinii (Buluh Semantan), collected from Bukit Larang Village in Melaka, Malaysia. Bamboo strips with average dimensions 300 mm x 5 0.5 were weaved plain-woven and divided into 2 6 laminate layers through E-glass ep...

It is shown that the nucleotide sequences in DNA molecules have clusterscaling properties (discovered for the first time in turbulent processes: Sreenivasan and Bershadskii, 2006, J. Stat. Phys., 125, 1141-1153.). These properties are relevant to both types of nucleotide pair-bases interactions: hydrogen bonds and stacking interactions. It is shown that taking into account the cluster-scaling p...

This paper provides a solution to the curse of dimensionality problem in the pairwise scoring techniques that are commonly used in bioinformatics and biometrics applications. It has been recently discovered that stacking the pairwise comparison scores between an unknown patterns and a set of known patterns can result in feature vectors with nice discriminative properties for classification. How...

The chain persistency of single-stranded (ss) DNA at a high-salt limit mainly arises from the so-called base-stacking interaction between consecutive bases along the strand. Stacking is appreciable for purine–purine (e.g., A–A) and purine–pyrimidine stacks (e.g., A–T), but it is weak for pyrimidine stacks (i.e., T–T, T–C, and C–C). We study how base stacking can stiffen the strand by classifyin...

Microstructural evolution under tribological load is known to change the friction and wear response of entire system. It however not yet fully understood, how these changes take place on an elementary, mechanistic level. Revealing temporal sequence deformation mechanisms a by experiments scarce. The discrete strain release in case twinning allows identification their sequence. Therefore, medium...

In this paper, two-dimensional (2D) orthotropic augmented finite element method (A-FEM) is applied to account for progressive failure of composite laminates under transverse loading, which considers all major cracking modes (delamination, fiber kinking/rupture matrix cracking). High-fidelity simulations different stacking loading are implemented. Both predicted load−deflection curves and damage...

Rapid growth of modern technologies such as internet and mobile computing are bringing dramatically increased e-commerce payments, as well as the explosion in transaction fraud. Meanwhile, fraudsters are continually refining their tricks, making rule-based fraud detection systems difficult to handle the ever-changing fraud patterns. Many data mining and artificial intelligence methods have been...

Magnesium alloys containing long-period-stacking ordered (LPSO) phases have attracted considerable attention because they have been reported to exhibit excellent mechanical properties, including high strength and reasonable ductility. It is thought that the LPSO phase plays a critical role in producing these favorable mechanical properties. We analyze the deformation behavior of the LPSO phases...
