Time Domain Spectral Finite Element Simulation of Ultrasonic Wave Propagation in Composite with Defects
Ultrasonic guided wave-based detection of structural defects or damages is one of the promising methods for structural health monitoring (SHM). A significant proportion of structural elements in an aircraft structure and ... -
Total Electric Field due to an Electron Avalanche and it's coupling to Transmission Line Conductors
Transmission of bulk electric power from the generating stations to the load centres can be carried out only through high voltages transmission lines. One of the main issues in the design and maintenance of extra and ... -
Towards Design and Development of Indigenous Rate-Grade MEMS Gyroscopes
Gyroscopes sense angular speed of the body on which they are mounted. Traditional mechanical gyroscopes are big, bulky, expensive, and hence limited to a few applications. With the advent of Micro-Electro-Mechanical Systems ... -
