The electric power grid wide-area monitoring system (WAMS) has been extended from the transmission to distribution level. As first WAMS deployed at level, frequency network FNET/GridEye uses global positioning system-time-synchronized monitors, called disturbance recorders, capture dynamic behaviors. In this paper, latest developments of monitor design and state-of-the-art data analytics applications are introduced. Its innovations uniqueness also discussed. Thanks its low cost, easy...
Alkenes and their related analogs are ideal starting materials for organic synthesis, the selective difunctionalization of alkenes, which allows simultaneous introduction two neighboring bonds, has gained considerable attention in recent years. In particular, photoredox-catalyzed alkenes also been accomplished, regarded as an increasingly powerful tool synthesis miscellaneous interesting molecular scaffolds environmentally benign economical manner. Several exquisite strategies have developed...
This paper presents a novel multi-document summarization approach based on personalized pagerank (PPRSum). In this algorithm, we uniformly integrate various kinds of information in the corpus. At first, train salience model sentence global features Naive Bayes Model. Secondly, generate relevance for each corpus utilizing query it. Then, compute prior probability and both. With help probability, Personalized PageRank ranking process is performed depending relationships among all sentences...
: Microplasma is a useful detector for analyzing the effluent of gas chromato-graphy due to its remarkable capacity portability, high sensitivity, and excellent multielement selectivity. Compared classical detectors, microplasma detectors have advantages small size, low cost, energy consumption in design operation. We aim provide an overview show their applications various chemical analyses. The operational characteristics analytical performance different such as capacitively coupled...
RTSP has been widely used in a variety of streaming media applications and service providers hope to choose high-performance server meet their needs, so it is an important research topic about how evaluate the serving performance server. This paper analyzes metric comprehensively, proposes approach design implement Performance Testing Utility for Streaming Server. According different stress test, utility mainly evaluates server's case delivering large number concurrent streams quantifies...
This study focuses on a ball stitch bump (BSOB) wire bonding process above laminate substrate by modeling and experiment. The goals of our are: (1) to determine the stress deformation mechanism BSOB substrate; (2) understand impact parameters. simulation includes ultrasonic transient dynamic process, wave transferred interface between bond structure substrate. Different material parameters are studied for optimized solution. force frequency discussed effects structures with partial supports....
The RANS (Reynolds-averaged Navier–Stokes equations) with CFD (Computational Fluid Dynamics) simulation method is used to analyze the head hump formation mechanism in double-suction centrifugal pump under a part load condition. purpose establish clear connection between and microcosmic flow field structure, reveal influence them. It found that diffuser stall causes change impeller capacity for work, this most critical reason formation. hydraulic loss of volute also hump, it analyzed using...
In this paper, a lead frame based system in package (SIP) for power management is examined. This built using multiple die types including IGBTs, diodes, and IC controllers. To maximize product performance the components use an ultra thin back grind. Thin dies minimize RDS(on), thermal performance, board standoff height by allowing to be thinner. However, could potential risk cracking if it done without careful evaluation, especially thickness as 90 /spl mu/m 50 mu/m. So critical understand...
As one of the main components injector II China ADS LINAC project, an RFQ working at 162.5MHz is used to accelerate proton beams 15mA from 30 keV 2.1 MeV. The four vane has been designed in collaboration with Lawrence Berkeley National Laboratory and built workshop Institute Modern Physics, Chinese Academy Sciences (IMP, CAS). Low power test cavity completed, it shows field flatness within ±1% unloaded Q 12600. RF conditioning results preliminary beam show output energy 2.16 MeV spread 3.5%...
The palladium‐catalyzed direct oxidative coupling reaction between 2‐aroylimidazoles with aromatic aldehydes or benzyl alcohols under oxidation conditions has been achieved to furnish a variety of carbonyl functionalized in moderate good yields. obtained products could be selectively transformed the corresponding phthalazines and phthalazin‐1(2 H )‐ones hydrazine hydrate as cyclization partner different temperature construct an array structurally diverse nitrogen‐containing heterocycles.
The reliability of core control network-element S-CSCF is the key premise for continual IMS services and deployment commercial networks. According to analysis S-CSCF's functions features, this paper proposes one design implementation method ensure S-CSCF, including contents consistency, fault detection, successive switch from main standby server recovery. mechanism implemented tested in open source OpenIMS Core project. experiment result shows that it a feasible, effective, low-cost method....
This paper studies the reliability of high power module package in torque mounting assembly process and temperature cycling by simulation. The package, which with initial warpage, will be mounted on an outer heat sink first follow test. A complicated 3D non-linear finite element model was developed to simulate these two processes together. warpage die stress/strain are discussed analyzed evaluate crack risk customer's application. simulation run firstly get package's status before mounting....
Pounding phenomenon between base-isolated structures under near-fault earthquakes has been widely investigated with various impact models around the world. Firstly, existing analysis are summarized and discussed in this paper. For Hertz-damp model, damping constant does not coincide its physical fact. Then, model was modified based on Hertz theory. Next, approximate formula of is theoretically derived, effectiveness verified by a simulation analysis. The numerical results show that pounding...
