We demonstrate the long linear-cavity with ultra-low repetition rate Ytterbium-doped fiber laser mode-locked by a SESAM. Output pulses were highly-chirped, with energies high to 75.2 nJ and minimum repetition rate was 191 kHz.

A service composition system can be constructed via integration and collaboration of many component services. The system performance needs to be obtained rapidly for the purpose of dynamic and adaptive management. An EGSPN (extended generalized stochastic Petri net) model is presented to reflect the service composition system with complex timing constraints in a compact and comprehensible manner. The various categories of timing constraints are associated to place, transition and arc of EGSPN respectively. Furthermore, in order to accelerate the calculation of system performance and to avoid the explosion of state space, a set of model reduction rules are presented. The corresponding reduction algorithms are designed to achieve automatic model reduction. The experiments based on multiform models indicate that a large model can be reduced within satisfying period. The algorithms can help to make rapid performance analysis of service composition system.

In recent years, the number of small size wind farms used as DG sources located within the distribution system are rapidly increasing. In this paper, wind farm made up with doubly fed induction generators (DFIG) is proposed as the continuous reactive power source to support system voltage control due to the reactive power control capability of DFIG. The particle swarm optimization (PSO) is utilized to find wind farm optimal reactive power output for distribution system losses reduction and voltage profiles improvement. Finally, the three feeder distribution system is used as a test case to evaluate the algorithm.

The Web services composition system usually has restricted resources in many practical applications. The system performance is closely related to the system resource. Firstly, a basic generalized stochastic Petri net model, constructed via service composition plan or language mapping for the purpose of performance presented. Nevertheless, the basic model can not reflect the characteristics of system resource restriction exactly. Therefore, through analyzing the various resource restrictions in Web services composition system, a series of extended modeling rules and methods are presented in order to acquire exact performance analysis results. The experiments indicate the difference of performance analysis results between basic model in ideal situation and extended model with restricted resources.
