In this paper we propose one allocation strategy and two strategies for sparse regenerator placement in translucent optical networks, namely Most Used Regenerator Placement (MURP) and Most Simultaneous Used Regenerator Placement (MSURP). The novel regenerators placement algorithms are compared with other ones presented in literature. They are tested on the proposed regenerator allocation algori...

In a travelling wave thermoacoustic device, the regenerator sandwiched between a pair of (hot and cold) heat exchangers constitutes the so-called thermoacoustic core, where the thermoacoustic energy conversion from heat to acoustic power takes place. The temperature gradient along the regenerator caused by the two heat exchangers excites and maintains the acoustic wave in the resonator. The dev...

We study the performance of a multichannel version [M. Vasilyev and T.I. Lakoba, Opt. Lett. 30, 1458 (2005)] of the all-optical Mamyshev regenerator in a practically important situation where one of its key components - a periodic-group-delay device - has a realistic amplitude characteristic of a bandpass filter. We show that in this case, the regenerator can no longer operate in the regime rep...

As a necessary component, regenerator plays an important role in the refrigeration performance of the pulse tube refrigerator. The objective of this research is to investigate the flow characteristics in a porous regenerator of the pulse tube refrigerators, subjected to oscillating flow. The hydrodynamic and thermal behavior of the regenerator is investigated by considering porous media approac...

We study the effects of periodic matter in kaon regeneration, motivated by the possibility of parametric resonance in neutrino oscillations. The large imaginary parts of the forward kaon-nucleon scattering amplitudes and the decay width difference ∆Γ prevent a sizable enhancement of the KL → KS transition probability. However, some interesting effects can be produced using regenerators made of ...

A new regenerator matrix design that improves the efficiency of a Stirling engine has been developed in a numerical study of the existing SM5 Stirling engine. A new, detailed, one-dimensional Stirling engine model that delivers results in good agreement with experimental data was used for mapping the performance of the engine, for mapping the effects of regenerator matrix temperature oscillatio...

We propose and numerically analyse an asynchronous digital optical regenerator using a single-EAM loop and a novel neighbor-combine approach. It effectively re-synchronizes input signals with arbitrary phases to the local clock, and regenerates signals with high amplitude fluctuation and polarization mode dispersion. We demonstrate the application of this regenerator for 4x40 Gbit/s WDM to 160 ...

As data communications rates climb toward 10 Gbits/s, clock recovery and synchronization become more difficult, if not impossible, using conventional electronic circuits. The high-speed photonic clock regenerator described in this article may be more suitable for such use. This photonic regenerator is based on a previously reported photonic oscillator capable of fast acquisition and synchroniza...

Along with the widely use in industries and lives, the dehumidification systems have consumed a large amount of energy. Fortunately, the application of liquid desiccant dehumidification system can greatly reduce the consumption of high-grade energy. To improve the advantages of liquid desiccant system compared with the conventional dehumidification system, one of the key measures is to increase...

A nominal 10.5-kW (3-ton) open-cycle liquid desiccant d ehumidification system has been design_ed, installed, and successfully operated at the Solar Energy Applications Laboratory, Colorado State Umvers1ty. Packed bed units were used to dry the air in the dehumidifier and to concentrate the desiccant _m the regenerator. Liquid distribution in the regenerator was studied for two systems: a gravi...
