CO2 capture from fossil fuel power plants is increasingly proposed for greenhouse gases emission mitigation. It can be applied to coal power stations (with boiler and steam cycle or with gasification) or to natural gas combined cycles (NGCC). The first case is probably the most important in a mid-term perspective, due to: (i) the larger amount of avoided carbon per unit of electricity produced,...

The energy crisis in recent years has led to the use of thermodynamic cycles that work based on renewable energies. Low-temperature cycles—such as organic cycles—are suitable strategies for the application of renewable energies. The present study proposes a novel cycle through the integration of a two-stage compression refrigeration cycle with a combined Rankine power and ejector refrigerat...

OBJECTIVE To compare the effect of letrozole with combined metformin and clomiphene citrate (CC) for ovulation induction in CC-resistant women with polycystic ovary syndrome (PCOS). DESIGN A randomized controlled trial. SETTING University teaching hospital and a private practice setting. PATIENT(S) Two hundred fifty anovulatory women (582 cycles) with CC-resistant PCOS. INTERVENTION(S) ...

We consider combined turbo decoding and channel estimation using pilot symbol assisted modulation (PSAM). When transmitting information on correlated fading channels, a channel interleaver is required to break up deep channel bursts. Our primary concern in this work is not the estimation scheme, but the interleaver pair (consisting of the channel interleaver and the turbo code interleaver), and...

Offers a means of increasing the efficiency cycle by reducing par asitic loads such as excess air compressor load and capturing energy that might otherwise be wasted. However, this is not always most effective way overall conver sion. For large gas turbine based plants in particular, best improving to add steam bottoming cycle, creat ing combined power plan. A plant simply what its name suggest...

We investigate the protection of network elements with non-simple p-cycles. We present four types of non-simple cycles; discuss the characteristics of non-simple cycles and present basic examples when and where non-simple cycles have an advantage compared to the protection with elementary cycles only. We develop a combined mathematical formulation for the routing and p-cycle optimization proces...
