In this paper, composite and hybrid materials were prepared using the hand lay-up method, with carbon, glass, Kevlar fabrics as reinforcing epoxy a matrix. The tensile test was performed to determine optimal ratio of resin in carbon fabric/epoxy, glass fabric/epoxy composites terms properties. It found that properties impregnate used fabric, fabric around 45%wt, 3%wt, 30 %wt, respectively. effe...

This paper presents the manufacturing development of laminated Carbon Fibre Reinforced Thermoplastics Polymer (CFRTP) specimens, which show significant improvement mechanical properties in comparison with existing thermoplastic composites. There is a need to improve structural performance composites by using fully integrated chopped and continuous carbon fibre bundle into resin matrix shape var...

Using an flexible representation of biological sequences, we have performed a comparative analysis of 1208 known tRNA sequences. We believe we our technique is a more sensitive method for detecting structural and functional relationships in sets of aligned sequences because we use a flexible representation (for sequences), as well as a general statistical method that can detect a wide range of ...

Many non-coding RNAs have been identified and may function by forming 2D and 3D structures. RNA hairpin and internal loops are often represented as unstructured on secondary structure diagrams, but RNA 3D structures show that most such loops are structured by non-Watson-Crick basepairs and base stacking. Moreover, different RNA sequences can form the same RNA 3D motif. JAR3D finds possible 3D g...

Object-stacking is a model for structuring object-based systems. The main feature of the object-stacking model is that layers of objects with a uniform interface are constructed, and the functions of these objects are integrated. In object-stacking, ltering functions are converted into objects. By implementing object-stacking in the World Wide Web, several ltering functions scattered all over t...
