Interest in eco-composites incorporating elements from recycling is growing to reduce the carbon footprint of final products. Therefore, characterisation surface properties recycled fibres first importance. However, order maximise service and facilitate their development, chemical treatments can be made improve compatibility with resins. For a better understanding behaviour these new reinforcem...

We construct a new static solution to the 5D Einstein-Maxwell equations describing a static black hole surrounded by a non-rotating dipole black ring. The configuration is kept in equilibrium by an external magnetic field interacting with the dipole charge of the black ring. The properties of the black Saturn-like configuration are studied and the basic physical quantities are calculated. The s...

The objective of this work is to investigate market power issues in bid-based hydrothermal scheduling. Initially, market power was simulated with a single stage Cournot–Nash equilibrium model. In this static model the equilibrium was calculated analytically. It was shown that the total production of N strategic agents is smaller than the least-cost solution by a factor of (N/(N +1)). Market pow...

Introduction Thermodynamic non-ideality can lead to serious problems in terms of the analysis of macromolecular behaviour in solution, particularly in molar mass and mass action measurements based on the principles of thermodynamic equilibrium. The term ‘molar mass’ (in g/mol) favoured by the physical chemist is of course equivalent to the molecular mass in daltons, and by ‘mass action’ we mean...

The interest in biped robots has highly increased in the last few years. The availability of cheap and advanced actuators and electronic controllers allowed the realization of many biped systems. There are some very famous humanoid robots, like the SONY SDR3X, or the HONDA Asimo. But there are also a lot of other biped robots at university research level. Many control strategy have been propose...

eart pressure problems are encountered in retaining walls, bulkheads, sheeting and bracing in cuts,culverts, tunnels, and cofferdams. in many cases, the lateral pressure is determined by use of classical earth pressure theories, such as coulomb's, where the equilibrium conditions of a failure wedge of soil is considered. excessive dynamic lateral earth pressure on retaining structures resu...

in this paper, three dimensional (3d) static and dynamic analysis of thick plates based on the meshless local petrov-galerkin (mlpg) is presented. using the kinematics of a three-dimensional continuum, the local weak form of the equilibrium equations is derived. a weak formulation for the set of governing equations is transformed into local integral equations on local sub-domains by using a uni...

the poly(ethyleneimine)-functionalized silica has been developed successfully as an effective adsorbent for the adsorption removal of cu(ii) ions from electroplating wastewater. the influences of ph, contact time and initial concentration of cu(ii) ions on the adsorption capacity and the effect of adsorbent dosage on the removal efficiency of cu(ii) ions from electroplating wastewater were inve...

based on three-dimensional theory of elasticity, static analysis of functionally graded carbon nanotube reinforced composite (fg-cntrc) cylindrical panel subjected to mechanical uniformed load with simply supported boundary conditions is carried out. in the process, stress and displacement fields are expanded according to the fourier series along the axial and circumferential coordinates. from ...
