High-coupling (KL = 3.0) phase-shifted DFB lasers are studied using a transmission-line laser model (TLLM), which includes spatial hole burning (SHB), the material gain spectrum, refractive index dependence on carrier concentration, and random spontaneous emission. Good agreement for CW spectra is shown with other models and experimental results. Dynamic simulations of laser transients show SHB...

The automobile suspension’s design incorporates three conflict criteria’s which are road handling, load carrying and passenger comfort. All these suspensions systems are generally require maintaining vehicle stability by reducing the effect of dynamic loads. The response of system is simulated by using the software “Symbol’s Shakti”. The bond graph model of the system with active and passive su...

The accelerating structure for the superconducting linac booster for the 15 UD Pelletron at IUAC is a Nb QWR cavity, designed and fabricated as a joint collaboration between IUAC and ANL, USA. Initial cavities required for the first linac module were fabricated at ANL. For fabrication of cavities required for future modules a Superconducting Resonator Fabrication Facility has been set up at IUA...

It is October, the first month of fourth quarter year. Fall has arrived, and weather where you are may be changing. Local stores have likely updated their inventory from fall décor to that upcoming holidays celebrated in final 2 months coffee shops filled with aroma pumpkin spiced lattes other delightful pumpkin-based treats. For some us, it brings joy one America’s favorite past-times, footbal...
