Abstract The development of fuel cell vehicles (FCVs) has a major impact on improving air quality and reducing other fossil-fuel-related problems. DC-DC boost converters with wide input voltage ranges high gains are essential to cells DC buses in the powertrains FCVs, helping improve low “soft” output characteristics. To build desired performance, their topologies have been widely investigated optimized. Aiming obtain optimal design range high-gain converter for review research status based...

Active development in new memory devices, such as non-volatile memories and high-bandwidth memories, brings heterogeneous systems (HMS) a promising solution for implementing large-scale with cost, area, power limitations. Typical HMS consists of small-capacity high-performance large-capacity low-performance memory. Data placement on plays critical role performance optimization. Existing efforts have explored coarse-grained data applications dense structures; however, thorough study that are...

Low-density polyethylene (LDPE), as an excellent dielectric insulating material, is widely used in electrical equipment insulation, whereas its low thermal conductivity limits further development and application. Hexagonal boron nitride (h-BN) filler was introduced into LDPE to tailor the properties of make it more suitable for high-voltage direct current (HVDC) cable insulation We employed melt blending prepare h-BN/LDPE thermally conductive composite materials with different contents....

Low-density polyethylene (LDPE) has excellent dielectric properties and is extensively used in electrical equipment. Hexagonal boron nitride (h-BN) similar to a graphite-layered structure, alumina fiber (Al2O3) high-temperature resistance strong performance. Herein, we prepared Al2O3-h-BN/LDPE nanocomposites by using LDPE as the matrix material h-BN Al2O3 fillers. The influence of different doping contents mass ratio (1:1) on thermal conductivity was examined. results showed that suppression...

To understand the functional behaviors of systems built on networks, it is essential to determine uncertain topology these networks. Traditional synchronization-based identification methods generally converge asymptotically or exponentially, resulting in their inability give timely results. The finite-time stability theory adopted this paper with aim addressing problem fast A novel observer proposed achieve and synchronization general complex dynamical networks time delay second-order...

The transient characteristics of the interface charges and electric fields in nonlinear/linear nonlinear/nonlinear dielectrics under different amplitudes dc step voltages polarity reversal are simulated using software Matlab-Simulink. simulation results show that double-layered not only relate with materials properties, but also average field. For between nonlinear field enhanced conductivity, establishing process polarization will get faster charge reverse as gets higher. maximum DC voltage...

Lithium-ion batteries may be slightly overcharged due to the errors in Battery Management System (BMS) state estimation when used field of vehicle power batteries, which lead problems such as battery performance degradation and stability degradation. Therefore, this paper conducts an experimental study on influence overcharging cycles degradation, builds a semi-empirical capacity model under basis. The results show that cycle causes decay significantly accelerated, its will also cause...

Multi-tenancy is one of the most attractive features cloud computing, which provides significant benefits to both clients and service providers by supporting elastic, efficient on-demand resource provisioning allocation. also introduces additional security auditing opportunities. Security can be consolidated offloaded onto a dedicated well-protected service. The timely prevention intrusive behaviour malicious processes using signature-based intrusion detection technologies or system call...

We consider the problem of designing sublinear time algorithms for estimating cost minimum metric traveling salesman (TSP) tour. Specifically, given access to a n × distance matrix D that specifies pairwise distances between points, goal is estimate TSP by performing only (in size D) queries. For closely related weight spanning tree (MST), it known any e > 0, there exists an O(n/e^O(1)) algorithm returns (1 + e)-approximate MST cost. This result immediately implies within (2 e) factor 0....

The event-driven programming model has been proposed to efficiently process iterative applications and incremental applications. In clusters based the model, are structured as a series of short triggers, each which will be invoked when associate events trigged. And framework assigns newly submitted trigger node where relevant datasets set. Unfortunately it may lead load imbalance because occur by chance. Numerous triggers in simultaneously but other nodes have no running. To end, we provide...
