in this study, forced-vibration analysis of a coupled system of single layered graphene sheets (slgss) subjected to the moving nano-particle is carried out based on nonlocal elasticity theory of orthotropic plate. two slgss are coupled with elastic medium which is simulated by pasternak and visco-pasternak models. using hamilton’s principle, governing differential equations of motion are derive...

Spoken and written languages evolve constantly through their everyday usages. Combining with practical expectation for automatically generating synthetic speech suitable for various domains of context, such a reason makes Text-to-Speech (TTS) systems of living languages require characteristics that allow extensible handlers for new language phenomena or customized to the nature of the domains i...

Online human interactions take place within a dynamic hierarchy, where social influence is determined by qualities such as status, eloquence, trustworthiness, authority and persuasiveness. In this work, we consider topic-based Twitter interaction networks, and address the task of identifying influential players. Our motivation is the strong desire of many commerical entities to increase their s...

In this paper, we consider medium access control of local area networks (LANs) under limited-information conditions as befits a distributed system. Rather than assuming “by rule” conformance to a protocol designed to regulate packet-flow rates (as in, e.g., CSMA windowing), we begin with a non-cooperative game framework and build a dynamic altruism term into the net utility. Our objective is to...

In the presence of operational context changes, many applications must use dynamic adaptations in order to meet requirements. When an application has a set of distributed objects that collaborates to offer a particular function, adaptations involving simultaneous distributed processes may affect such collaborations, planning distributed adaptations is thus a complex task for developers. This pa...

Recent numerical simulations of the interstellar medium driven by energy input from supernovae and stellar winds indicate that H I clouds can be formed by compression in shock waves and colliding turbulent streams without any help from thermal and gravitational instabilities. The filling factor of the hot phase in these models does not exceed 20–40% at the midplane. The hot gas is involved in a...

in this paper, the mechanical behavior of three-phase inhomogeneous materials is modeled using the meso-scale model with lattice beams for static and dynamic analyses. the timoshenko beam theory is applied instead of the classical euler-bernoulli beam theory and the mechanical properties of lattice beam connection are derived based on the continuum medium using the non-local continuum theory. t...
