A nanogrid that consists of four fluorenes and two carbazoles has been synthesized by molecular installing technology from an L-shaped synthon.
In order to investigate the influence of covalent bonding within garnet framework on conductivity Li+ in interstitial space, conductivities family Sn-based compounds Li6La3SnMO12 (M = Sb, Nb, Ta) have been obtained and are compared with those Li6La3ZrMO12. Refinement neutron diffraction pattern Li6La3SnNbO12 shows that tetrahedral sites (24d) about half-occupied most Li bridging octahedral displaced from center position (48g). The Sb-based compound has largest lattice parameter while...
This paper proposes VM-μCheckpoint, a lightweight software mechanism for high-frequency checkpointing and rapid recovery of virtual machines. VM-μCheckpoint minimizes checkpoint overhead speeds up by saving incremental checkpoints in volatile memory employing copy-on-write, dirty-page prediction, in-place recovery. In our approach, knowledge fault/error latency is used to explicitly address corruption, critical problem, especially when frequency high. We designed implemented the Xen VMM. The...
The increasing use of smart meters enables the monitoring and diagnostics underlying systems. application data analysis methods can help to automate such that human intervention is limited situations where when it necessary. In a grid, relate faulty unusual consumption, corresponding point anomalies contextual anomalies. This work compares Deep Neural Network Regression, an Autoencoder with reconstruction, encoder as anomaly detection methods. three models are evaluated on real-world...
Compared with traditional liquid electrolytes, solid polymer electrolytes possess higher reliability and safety but lower ionic conductivity, which can be improved by incorporating plasticizers to form gel (GPEs).
With the demand for energy sustainability and development of low-carbon power system, distributed energy, storage, response, other diverse market participants will participate in electricity market, which brings new changes to transaction organization process market. This paper first introduces under participation from two aspects transactions power. Diverse can provide a variety auxiliary services while they have potential process. Secondly, current supervision measures used foreign order...
For the sustainable development of smart cities across globe, energy efficiency is becoming a major factor to maintenance and planning buildings. In order demonstrate potential data driven approaches in understanding building usage, we conduct analysis study based on 10-year set from 361 buildings university campus that are equipped with 1951 meters. The preliminary results obtained our presented. Results both clustering prediction offer better common usage as well identification anomalous...

In order to realize long-distance, long-term and on-line cable tension monitoring of suspension bridges, a novel sensor has been designed based on Fiber Bragg Grating (FBG) sensing technique, which comprises fixtures the as well FBG, micro-spring epoxy resin made large gauge element. Further, following calibration test for FBG sensor, research calibrated was carried out, whose result shows that, featured by simplicity operation accurate data, is capable built bridges.
Three groups of GCr15 steel were heat-treated respectively by conventional spheroidizing annealing, circulation 1050°C for 30min oil cooling quenching + 700°C tempering. The final heat treatment these was 840°C 150°C microstructure the observed and mechanism three discussed in this paper. results showed that: There is obvious difference among carbide treatments different. has tempering best result spheroidizing. after 150 °C tempered martensite which fine, round widely distributed.
