Application of Information and Communication Technology for Dissemination of Agricultural Information among Farmers: Challenges and Opportunities

Agriculture is the backbone of India’s economy as two-third of the population live in rural areas and directly or indirectly depend on agriculture for their livelihood. India’s food production has improved significantly during the last three decades due to all-round efforts but Indian agriculture is still facing a multitude of problems to maximize productivity to feed the continuously increasin...

Power Supply and Current Modulation Circuits for Semiconductor Lasers

Design and construction of a stable current supply with protection circuits are described. The reported circuit provides a high-stable and high-level current variable from 0.5-1.2 A with the protect ion circuits to prevent over load current, voltage and off-range temperature operation. A detailed analysis of the circuit parameters is given and the time behaviors of the load voltage/current and ...

Synchronization and Communication Using Semiconductor Lasers With Optoelectronic Feedback

Semiconductor lasers provide an excellent opportunity for communication using chaotic waveforms. We discuss the characteristics and the synchronization of two semiconductor lasers with optoelectronic feedback. The systems exhibit broadband chaotic intensity oscillations whose dynamical dimension generally increases with the time delay in the feedback loop. We explore the robustness of this sync...
