Performance Degradation of 100Gb/s PM-QPSK and 400 Gb/s PM-16QAM Coherent Communication Systems Due to Optical Filter Cascade and Chromatic Dispersion
(2013-01)
In the near future, data rates of 100 Gb/s and 400 Gb/s will be used to match the increase in bandwidth demand for capacity. Wavelength division multiplexing (WDM) systems transmit multiple wavelengths simultaneously at ...
Optimization of Commercially Off the Shelf (COTS) Electric Propulsion System for Low Speed Fuel Cell UAV
(2013-03)
Fuel cell technology offers higher energy density than any other onboard electric power source. However, despite its high energy content per unit mass, the fuel cell is lacking in power density ratio compared to Lithium-Polymer ...
Prediction of Stability Limits for Binary and Ternary Systems Using the NTRL Liquid Phase Model
(2013-01)
Stability limits (spinodal loci) were determined for 53 binary systems and 26 ternary systems. Rigorous thermodynamic criteria for spinodal limits and criticality conditions in terms of mixture Gibbs free energy were derived ...
Integrated Renewable Energy Options for HVAC-Cooling Systems
(2013-06)
The demand for energy is increasing at an unexpected rate all over the world. Most of the present worldwide energy usage is based on fossil fuel and results in continuous depletion of this resource. Conventional Heating ...
