A high voltage DC pulse power supply of -50kV, 10A for high power application was designed and developed (Fig 1). The system has a variety of features such as independent control of Pulse Repetition Frequency (PRF), Pulse Duration (Ton) and Pulse Amplitude. Two sets of -25 kV, 10A pulse power supply were developed and tested with [...]

Fatigue is a problem with severe consequences for drivers and people who work in high-risk situations such as mining, operation of heavy machinery, and for workers in factories, chemical/nuclear plants, etc. Current methods to implement fatigue detection in automotive sector include techniques such as blink frequency detection, posture/movement analysis etc. However, the reliability of these methods [...]

With the rapid growth of cities, the need for a renewable source of energy is increasing. Simultaneously, the growth of cities has left limited space for installations of renewable energy sources which require a large area. Similarly, installations of large renewable energy farms on the outskirts of cities and rural area leave less space for the [...]

An agreement was signed between M/s. Krystalvision Image Systems Pvt. Ltd. and CSIR-CEERI on 4th November 2015 for undertaking the above project. The project was commenced on 4th November 2015 and its duration was for seven months. This project was aimed at developing material discrimination technique based on an atomic number and density of scanned items [...]

A 42 GHz Gyrotron with indigenous design, development and characterisation technology as well as infrastructure development was the main objective of the project. The design and fabrication of technologies for every component and for the entire gyrotron have been developed. The gyrotron was first of its kind to be developed in the country. It was transported [...]

The work demonstrates a simple, handheld, micro-heater integrated MOX-based gas sensor interface system that includes digital set point, a precise closed loop temperature controller and a wide range resistance readout circuit. The implementation of the proposed system constitutes two circuits. The temperature control loop circuit is able to set the platinum microheater temperature over a range [...]

Structural Health Monitoring (SHM) of buildings using Wireless Sensor Network (WSN) includes sensor selection, sensor placement & optimisation on a selected building. The monitoring of selected building is to be carried out for a period of two years to detect changes in dynamic behaviour if any. For this, the changes in dynamic properties of buildings, theoretically [...]

Acoustic Sensors is a device, which can monitor physical, biological, and chemical stimulus by producing an electrical signal. The miniature acoustic sensor developed so far have focused primarily on hearing aid applications and therefore, most of the researchers concentrated on acoustic detection only in a limited audio range. Moreover, the measurement of high sound pressure level [...]
