Hospital Bedrails In this paper, a novel image encryption scheme is proposed for the secure transmission of image data.A self-synchronous chaotic stream cipher is designed with the purpose of resisting active attack and ensures the limited error propagation of image data.Two-dimensional discrete wavelet transform and Arnold mapping are used to scra
Solar sails are propellantless systems where the propulsive force is given by the momentum exchange of reflecting photons.In this study, a self-deploying system based on NiTi shape memory wires and sheets has been designed and manufactured.A small-scale prototype of solar sail with carbon fibre loom has been developed.Different Hospital Bedrails co
Modern organizations have migrated from localized physical offices to work-from-home environments.This surge in remote work culture has exponentially increased the demand for and usage of Virtual Private Networks (VPNs), which permit remote employees to access corporate offices effectively.However, the technology raises concerns, including security
