A study suggests that the first of seven key pyramids in Egypt, the Step Pyramid of Djoser, was built using a hydraulic lift. Dated to about 4,500 years ago, this would move up the introduction of ...

Abstract: It is well known that most position synchronization control schemes merely relay on position error dynamics, which are hard to fully explore the potential ...

A hydraulic system controls the transmission of energy. It transforms the mechanical energy of a prime motor into fluid energy. It controls the fluid configuration and transforms the fluid energy into ...

Abstract: A severe nonlinearity of hydraulic pump system with switched reluctance motor (SRM) drive makes it hard to get a good control performance with a conventional PID controller. A novel ...

A peer-to-peer wireless communication system using Arduino Uno, a 16×2 I2C LCD Display and NRF24L01 transceiver modules to transmit and receive Morse code messages. This project demonstrates encoding ...

Ask the publishers to restore access to 500,000+ books. An icon used to represent a menu that can be toggled by interacting with this icon. A line drawing of the Internet Archive headquarters building ...
