Thermoacoustic converters are devices for direct conversion of acoustic energy into thermal in the form temperature difference, or vice versa – converting an wave. In first case, device is called a thermoacoustic heat pump, second engine. can use (or produce) standing travelling This paper describes construction and properties single-stage engine with kind works using Stirling cycle. It uses ga...

in order to increase the rate of gas absorption, chemical reaction in the liquid phase is considered. the purpose of this paper was to simulate gas absorption process by a liquid film over a spherical packing incorporating eddy viscosity and diffusivity. second order chemical reaction for two different cases (fast and slow) were considered. the system partial differential equations obtained was...

We deal with the Regenerator Location Problem in optical networks. We are given a network G = (V,E), and a set Q of communication requests between pairs of terminals in V . We investigate two variations: one in which we are given a routing P of the requests in Q, and one in which we are required to find also the routing. In both cases, each path in P must contain a regenerator after every d edg...

We present the results of studies of fiber ring reflectors that are pulse excited in the negative dispersion regime. An intensity-dependent fiber switch is proposed for improved thresholding and pulse output characteristics over those previously reported. Schemes for fiber switches relying on solitary-wave collisioninduced phase shifts are also discussed. A pulse regenerator and logic gates are...

All optical buffering within high-speed optical time division multiplexing (OTDM) based networks is becoming a necessity. In this paper, an active all-optical recirculating fibre loop buffer (RFLB) employing an alloptical regenerator to compensate for pulse distortion is introduced. The OTDM pulse shape is soliton and the data rate used is 20 Gb/s. Simulation results for the bit error rate (BER...

Solar thermal energy-powered air conditioning technologies are receiving increased attention. Among the solar energy-driven cooling technologies, open type liquid desiccant (AC) system is emerging as a promising technology, which has driven solution regenerator. In this of system, evaporation water and concentrating or regenerator performance determines AC necessitates its development experimen...
