This paper addresses the problem of task allocation in real-time distributed systems with the goal of maximizing the system reliability, it has been shown to be NP-hard. Many studies have been made to solve this problem without considering the real-time constraint. We first take account of the deadline constraint in order to formulate this problem, and then(More)
Comparing teleseismic array back-projection source images of the 2011 Tohoku-Oki earthquake to results from static and kinematic finite source inversions has revealed little overlap between the regions of high and low frequency slip. Motivated by this interesting observation, back-projection studies extended to intermediate frequencies, down to about 0.1Hz,(More)
Through the combination of the divergent and convergent approaches, coupled with the utilization of the powerful Sharpless "click-chemistry" reaction, two series of sulfonyl-based high-generation NLO dendrimers were conveniently prepared with high purity and in satisfactory yields. Thanks to the perfect three-dimensional (3D) spatial isolation from the(More)
By the combination of divergent and convergent approach, a new series of NLO dendrimers (G1-PFPh-NS-GL to G3-PFPh-NS-GL) was conveniently prepared with satisfied yields through the powerful "click chemistry" reaction, in which perfluoroaromatic rings were introduced in the periphery, two types of chromophores were arranged with regular AB structure, and(More)
Herein, through a combination of divergent and convergent approaches, coupled with the utilization of the powerful Sharpless "click chemistry" reaction, two series of high-generation nonlinear optical (NLO) dendrimers have been conveniently prepared in high purity and satisfactory yields. Perfluoroaromatic rings and isolation chromophores were introduced to(More)
By modifying a synthetic procedure, two new hyperbranched polytriazoles (HP1 and HP2) containing isolation chromophores were synthesized successfully through click chemistry reactions under copper(I) catalysis. For the first time, these two polymers were derived from an AB(4)-type monomer, although they contain different end-capping chromophores. They are(More)
On the hardware platform of Distributed Real-Time Simulation, a communication module based on reflective memory network was realized in FPGA. As an infrastructure module, it could be integrated with other modules seamlessly. Under the speed-first rules, DMA engine in PCI Master mode was designed, and 64bits/32bits bus compatibility was realized. In order to(More)
