Silane coupling agents have been frequently used as interfacial agents in polymer composites to improve interfacial strength and resistance to fluid migration. Although the capability of these agents in improving properties and performance of composites has been reported, there are still many uncertainties regarding the processing-structure-property relationships and the mechanisms of coupling ...

In this work, the calculated nuclear quadrupole coupling constants of O in some styrylquinoline conformers were presented. The calculations were carried out to find the relationships between the charge distribution of styrylquinolines and their pharmaceutical behavior and to explore the differences among the electronic structures of some conformers of these potent HIV IN inhibitors. Furthermore...

The reactivity of immobilized functional groups in thin layers of (3-aminopropy1)triethoxy~ilane (APS), (3-mercaptopropyl)trimethoxy~ilane, (3-bromopropyl)trimethoxysilane, and (8-bromoody1)trimethoxysilane on oxidized aluminum substrates was studied with reflection-adsorption infrared spectroscopy (RAIR), optical ellipsometry and contact-angle measurements. Mass changes on the surface associat...

Multi agents systems are formed of different independent entities placed in several machines. When an entity or an agent fails, it is the whole system that may be in a failure case. Through this paper, we will propose an approach that may guarantee fault tolerance in multi agents systems using two different techniques which are replication and exception handling. Replication uses redundancy to ...

The durability of titanium (Ti) alloys bonded with high temperature adhesives such as polyimides has failed to attain the level of performance required for many applications. The problem to a large part is attributed to the instability of the surface treatment on the Ti substrate. Although Ti alloy adhesive specimens with surface treatments such as chromic acid anodization, Pasa-Jell, Turco, et...

Bioabsorbable phosphate glass fibre/polymer composites are being investigated as alternatives to commonly used metal alloy-based bone fracture fixation devices. According to Knowles [1], these ‘Third Generation’ implants remain in the body for the short term necessary for mechanical stabilisation of tissue. In addition the degradation products of the bioabsorbable implants perform an active fun...

Fourteen novel silane coupling agents with a quaternary ammonium group introduced into the molecule, [CH(2)=CHCH(2)N(+)(CH(3))(C(n)H(2n+1))(CH(2))(3)Si(OCH(3))(3)]X(-) (n-X, n=10-18, X=Cl, Br, or I), were synthesized with the aim of using these agents to make material surfaces antimicrobial for a long period of time. Measurements of the minimum inhibitory concentrations (MIC) against 12 kinds o...

In this paper, we consider a leader-following consensus problem of a group of autonomous agents with time-varying coupling delays. Two different cases of coupling topologies are investigated. At first, a necessary and sufficient condition is proved in the case when the interconnection topology is fixed and directed. Then a sufficient condition is proposed in the case when the coupling topology ...

Inspired by existing works, in this paper, we propose software architecture for coupling the MAS and DEVS formalism. This architecture is designed to enable the modeling of large quantities of agents. Previous works often associated with an agent to a DEVS model. The complexity of the system increases proportionately with the number of agents. We describe an approach to group a set of agents in...
