this paper investigates the lateral vibration of single-layered graphene sheets based on a new theory called doublet mechanics with a length scale parameter. after a brief reviewing of doublet mechanics fundamentals, a sixth order partial differential equation that governs the lateral vibration of single-layered graphene sheets is derived. using doublet mechanics, the relation between natural f...

energy consumption is considered as a critical issue in wireless sensor networks (wsns). batteries of sensor nodes have limited power supply which in turn limits services and applications that can be supported by them. an efcient solution to improve energy consumption and even trafc in wsns is data aggregation (da) that can reduce the number of transmissions. two main challenges for da are: (i)...

Magma migration and differentiation processes are key to understanding the development evolution of oceanic magma reservoirs. To provide new quantitative geochemical constraints on these processes, we applied a high-resolution approach study an interlayered section lower crust sampled at Atlantis Bank, (ultra)slow-spreading Southwest Indian Ridge. The is characterized by sharp grain-size layeri...

Introduction: The acoustic performance of natural fiber adsorbents has been investigated in numerous studies. A part of these materials show a poor adsorption within the frequency range of less than 1000 Hz. In the present study, attempts were made to investigate the effect of layout sequence of double-layered composites consisting of natural and synthetic fibers on improving the acoustic adsor...

An intrusion response system is charged with minimizing any losses caused by intrusion. It remains ineffective if the response to the intrusion does not bring the timely and adequate corrections required by the victim system. This paper proposes a new intrusion response system based on contextual fuzzy cognitive map. In this intrusion response system framework, a new ontology is defined based u...
