Thermomagnetic Convection in a Ferrofluid Layer with Throughflow
Abstract: The effect of vertical throughflow on the onset of thermomagnetic convection in a ferrofluid layer in the presence uniform vertical magnetic field is investigated theoretically. Both the boundaries are considered to be rigid-ferromagnetic and insulated to temperature perturbations. The resulting eigenvalue problem is solved numerically using the Galerkin technique as well as analytically by regular perturbation technique with wave number as a perturbation parameter. Results show that the effect of …

Self-Healing Graphene–Polymer Nanocomposite Encapsulation Layers for Ultra-Stable Perovskite Photovoltaic Modules under Extreme Environmental Conditions
Abstract: The recent trend is that perovskite photovoltaic modules are vulnerable to moisture, oxygen, thermal cycle, UV, and mechanical stress, which seriously affect the working stability of the modules under harsh environmental conditions, thereby hindering the rapid commercialization. In this study, a new self-healing graphene–polymer nanocomposite encapsulant layer is proposed to improve the durability and reliability of perovskite solar modules in extreme climates. The encapsulation system combines functionalized graphene nanosheets into …

Power and Congestion Control Analysis for MANET in NS3
Abstract: AbstractRouting to MANET is difficult due to the navigation feature. The main causes of connection failure are mobility, interference, and congestion. Mobility means that each node is free to move within its transport area. The interference is due to a collision and a hidden node. A hidden node means two nodes outside the radio frequency range of each one while trying to transmit data to an intermediate node located in …
