3 Theoretical properties of the ” projected composites ”
نویسنده
چکیده
The new possibility to explain the nature of the thermal X-ray composites (TXCs) as projection effect of 2-or 3-dimensional shell-like supernova remnants (SNRs) evolved in a nonuniform medium is proposed. X-ray and radio morphologies as well as basic theoretical features of such an SNR and surrounding medium are considered. It is shown that the theoretical properties of the shell-like SNR evolved at the edge of molecular cloud with gradient of ambient density along the line of sight correspond to observed properties of TXCs very well. So, at least a part of the objects from the class may be interpreted in the frame of the considered effect.

Synthesis of Polyaniline/Polyamide composites as membrane and investigation of its properties
Practical applications of conducting polymers such as polyaniline as membranes are particulary limitedbecause of their poor mechanical properties. However by mixing polyaniline with some conventional insulatingpolymers such as nylon and preparation composite films through solvent casting or blending, it seems to be asuitable way in order to increase the mechanical properties of the conducting p...
متن کاملInvestigation of Mechanical Properties Prediction of Synthesized Nylon-66/Nano-Calcium Carbonate Composites
In this research, the influence of adding micro- and nano- sized calcium carbonate powders to nylon-66 was investigated. Mechanical properties of micro and nano- composites, including tensile strength, elongation, and Young’s modulus, before and after ageing, were determined and analyzed. For this purpose, micro- and nano-sized CaCO3 particles were used as fillers to prepare micro-composites (c...

In this study, carbon nano fibers (CNFs) were mixed into epoxy resin through a magnetic stirrer and again mixed using ultra sonicator. Using hand layup technique, biaxial braided fiber composites were prepared with unfilled, 0.2, 0.5 and 1 wt% CNF. Tensile test and shear test was performed to identify the tensile strength and shear strength of the composites. Fractured surface of the tensile sp...
متن کاملPROJECTED DYNAMICAL SYSTEMS AND OPTIMIZATION PROBLEMS
We establish a relationship between general constrained pseudoconvex optimization problems and globally projected dynamical systems. A corresponding novel neural network model, which is globally convergent and stable in the sense of Lyapunov, is proposed. Both theoretical and numerical approaches are considered. Numerical simulations for three constrained nonlinear optimization problems a...
