A virtual cluster is a promising technology for reducing management costs and improving capacity utilization in datacenters and computer centers. However, recent cluster virtualization systems do not have the maximum scalability and flexibility required, due to limited hardware resources at one site. Therefore, we are now developing an advanced cluster management system for multi-site virtual c...

An in situ time-resolved X-ray diffraction (XRD) system for hydrothermal reaction has been developed in order to investigate the phase evolution during autoclave process in autoclaved aerated concrete (AAC) formation. The system includes a novel autoclave cell for transmission XRD with thin beryllium windows, a two-dimensional photon-counting pixel array detector, and uses high energy X-rays fr...

In order to enhance the catalytic performance of SAPO-34 catalyst for the reaction of methanol to olefins (MTO), ultrasonic and microwave-assisted aging method were employed in static hydrothermal method to synthesize nano-sized SAPO-34. The effects of the application of this method on the chemical composition, morphology, surface area and total acidity of SAPO-34 were characterized by XRD, FE-...

Multi-stage magmatic events associated with large tungsten-tin polymetallic deposits in the Nanling Range have been subject of extensive research spanning many years. In this paper we report results a systematic study petrology, whole-rock geochemistry, zircon U-Pb chronology, and trace element geochemistry granite bodies exposed Xianghualing ore field. They show that granites area are characte...

The site and character of precious and basemetal epithermal deposits is determined by several principal factors which include: structure, stratigraphy, lithology, pressure and temperature. hydrology, chemistry of the mineralizing fluid, and syn-hydrothermal development of permeability or changes in hydraulic gradient (White and Hedenquist, 1990). This study investigates the syn-hydrothermal dev...

Single-crystalline SnO2 microcubes were grown using the hydrothermal method without any catalyst. X-ray diffraction (XRD) patterns and energy dispersive X-ray (EDX) analysis verified that the cubes are tin dioxide SnO2. Their morphology and structure was studied by scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and Raman 5m...

A multi objective Honey Bee Mating Optimization (HBMO) designed by online learning mechanism is proposed in this paper to optimize the double Fuzzy-Lead-Lag (FLL) stabilizer parameters in order to improve low-frequency oscillations in a multi machine power system. The proposed double FLL stabilizer consists of a low pass filter and two fuzzy logic controllers whose parameters can be set by the ...
