Face mask detection has made considerable progress in the field of computer vision since start Covid-19 epidemic. Many efforts are being to develop software that can detect whether or not someone is wearing a mask. methods and strategies have been used construct face models. A created model for detecting masks described this paper, which uses “deep learning”, “TensorFlow”, “Keras”, “OpenCV”. Th...

The ability to stop a gear fatigue test before catastrophic failure has many advantages. However, today, widely accepted approach is not available. This case study applies vibration-based condition monitoring methodology detect early failures. studied takes part in an all-wheel-drive drivetrain system. Vibration signals from four run-to-failure tests at two constant torque-speed combinations we...

The general polymerase chain reaction (PCR) amplifies DNA and analyzes the amplification results of quantified DNA. Recently, real-time PCR has been developed to detect in various ways. conventional camera-based system is too expensive difficult reduce device size. In this paper, we propose a low-cost, compact fluorescence detection for systems using an open platform camera. To simplify optics,...
