In OFS, users employ an off-band signaling protocol to request lightpaths for their large unscheduled bursty transactions, and the network dynamically schedules a dedicated, end-to-end lightpath for the duration (≥100mS transaction times) of the transfer avoiding collisions due to contention, Fig.1. For OFS the scheduling and network control is dynamic and when a transaction finishes, the network resources are immediately relinquished to other users. The key to high utilization of backbone wavelength channels - a precious network resource owing to the necessary use of optical amplifiers and dispersion management - is statistical multiplexing of large flows from many users in a scheduled fashion. Efficient, dynamically assigned multi-access broadcast groups can be arranged for multiple transaction durations using the node architecture. We have shown, [1,2,3,4,6], that our approach provides significant cost savings over other transport mechanism for large transactions. OFS is technically a circuit switched service. The major difference between OFS and traditional circuit switching is the fast dynamic session setup (100S). We use a MAN network architecture that exhibits a decreasing cost/user/data-rate as the number of users and user data-rates increase. The following Quasi-static WAN for scalable network management/ control1H2HiHkHjHSDQuasi-control are key design features for the MAN architecture: a. Minimize average lightpath lengths, in terms of the number of OXCs traversed. b. Use of quasi-static MAN/LAN broadcast groups to eliminate fast per session,

The linear and non-linear FE-based model of a three phase wound rotor induction machine is presented. The effect of stator and rotor currents on the self and mutual inductance is considered. The mathematical representation of the machine in presence of saturation is developed. The calculated model is compared with a simple d-q model, full FE-model, and a linear FE-based phase variable model. The calculated result shows a good match in accuracy with full-finite element model and in run-time with the d-q model.

In this paper a planar inductor based resonant circuit is designed for zero-current switching (ZCS) buck converter. The electromagnetic behavior of the design is analyzed by finite element (FE) methods for EMI interactions. A high frequency model for conducted EMI in the resonant circuit is obtained. To suppress the conducted EMI in the circuit, a method based on the resonant circuit impedance control is proposed. All the results are compared to conventional circuits and improvement in responses were observed and verified through simulation and laboratory experimentation.

We present a theory of the multi-threshold second-order phase transition,and experimentally demonstrate the multi-threshold secondorder phase transition *** carefully selected parameters,in an external cavity diode laser system,we observe secondorder phase transition with multiple(three or four) thresholds in the measured power-current-temperature three dimensional phase *** controlled death and revival of second-order phase transition sheds new insight into the nature of ubiquitous secondorder phase *** theory and experiment show that the single threshold second-order phase transition is only a special case of the more general multi-threshold second-order phase transition,which is an even richer phenomenon.
Present-day networks are challenged by dramatic increases in data rate demand of emerging applications. A new network architecture, incorporating "optical flow switching", will enable significant rate growth...
