Control Chart for Attributes based on Inverse Rayleigh Distribution
Abstract: In this paper, a new attribute control chart based on inverse Rayleigh distribution is developed under a time truncated life test. The number of failures is observed from the life test and the fraction nonconforming is to be monitored by two pairs of lower and upper control limits. The simulation study shows the efficiency of the developed chart. An example is provided for illustrating the new control chart.Cite this ArticleKowsalya …

Artificial Intelligence–Assisted Reduced-Order Modeling and Stability Control in Granular Couette Flow
Abstract: This study develops a reduced-order and stability-aware modeling framework for dense granular Couette flow by integrating continuum mechanics, bifurcation analysis, and data-driven stability estimation. Starting from coupled governing equations for momentum, granular temperature, and microstructural evolution, the system is nondimensionalized and reduced using a Galerkin projection consistent with shear-driven boundary conditions. This yields a low-dimensional nonlinear dynamical system that preserves the essential coupling between velocity, fluctuation energy, and structural relaxation. …

Hand Gesture Controlled Drone
Abstract: Unmanned Aerial Vehicles, also known as drones, are the aircrafts that can be operated without a human pilot on board of the aerial vehicle. Drones can be navigated from the ground, using a GPS tracking system. Drones are traditionally operated using remote controllers, joysticks, mobile applications, and embedded computers. Some important problems previously faced with these approaches are that drone controlling is limited to the range of electromagnetic radiation and …
