Optimal power management of shipboard power system for failure mode (OPMSF) is a significant and challenging problem considering the safety of system and person. Many existing works focused on the transient-time recovery without consideration of the operating cost and the voyage plan. In this paper, the OPMSF problem is formulated considering the mid-time scheduling and the faults at bus and generator. Two-side adjustment methods including the load shedding and the reconfiguration are coordinated for reducing the fault effects. To address the formulated non-convex problem, the travel equality constraint and fractional energy efficiency operation indicator (EEOI) limitation are transformed into the convex forms. Then, considering the infeasibility scenario affected by faults, a further relaxation is adopted to formulate a new problem with feasibility guaranteed. Furthermore, a sufficient condition is derived to ensure that the new problem has the same optimal solution as the original one. Because of the mixed-integer nonlinear feature, an optimal management algorithm based on Benders decomposition (BD) is developed to solve the new one. Due to the slow convergence caused by the time-coupled constraints, a low-complexity near-optimal algorithm based on BD (LNBD) is proposed. The results verify the effectivity of the proposed methods and algorithms. Copyright © 2017, The Authors. All rights reserved.

In this paper, four elements fractal shape antenna with non-uniform annular ring Photonic Band Gap (PBG) etched in the ground is presented. The impact of the PBG structure in removing the undesired harmonic frequencies of the proposed antenna is demonstrated. The proposed antenna is designed, fabricated and tested. The results show that the designed antenna is capable of resonating at three different frequencies of 915 MHz, 1.8 GHz and 2.45 GHz with high-efficiency performance in terms of return loss, gain and radiation pattern characteristics with compact size. Good agreement between the measured and the simulated results is observed.

Solar-driven water splitting using powdered catalysts is considered as the most economical means for hydrogen generation. However, four-electron-driven oxidation half-reaction showing slow kinetics, accompanying with insufficient light absorption and rapid carrier combination in photocatalysts leads to low solar-to-hydrogen energy conversion efficiency. Here, we report amorphous cobalt phosphide (Co-P)-supported black phosphorus nanosheets employed as photocatalysts can simultaneously address these issues. The nanosheets exhibit robust hydrogen evolution from pure water (pH = 6.8) without bias and hole scavengers, achieving an apparent quantum efficiency of 42.55% at 430 nm and energy conversion efficiency of over 5.4% at 353 K. This photocatalytic activity is attributed to extremely efficient utilization of solar energy (~75% of solar energy) by black phosphorus nanosheets and high-carrier separation efficiency by amorphous Co-P. The hybrid material design realizes efficient solar-to-chemical energy conversion in suspension, demonstrating the potential of black phosphorus-based materials as catalysts for solar hydrogen production.

This paper describes the development of a Cloud-based solid cutting simulation service system for 3D toolpath verification before it is to be uploaded to a CNC machine tool for machining operation. A user can access the system through common WWW browsers such as Internet Explorer and/or Google Chrome in either a PC running Microsoft Windows, a smart phone running Android, or an iPad running iOS. The system can perform real time solid cutting simulation based on the toolpath (NC program). The system provides user with standard views such as 'ISO View', 'Front View', 'Right View', and 'Top View';dynamic customized 3D view could be controlled through the mouse operation on the client side to ease the visibility during the simulation. The proposed system has been successfully implemented on a public cloud system Microsoft Azure with expected performance and is expected to assist a user in verifying the correctness of the toolpath and to enhance the efficiency in a geographically dispersed networked environment. © 2016 IEEE.

A tri-band fractal structure for Agriculture, WLAN and GSM band applications is presented. The desired resonances are 0.915, 1.8 and 2.45 GHz. This antenna consists of a modified 90 degree Koch fractal resonator, two layer substrates which are separated by an air gap layer and then fed through the SMA port and finally simulated on RT/Duroid 5880. Fractal shapes have been used to have a multi-band frequencies with a reduction in size. Furthermore, inductive and capacitive loadings have been applied though some stubs, gaps and two shorting posts to reduce the size. Thereafter, the equivalent circuit of the proposed antenna designed based on the literature. The uniqueness of the antenna is the miniaturized size (90 × 90×10mm~3) compared to the first resonant frequency with high performance. The measured results performed on the performance of the proposed antenna, which has a good agreement with the simulation results.

In 2012, the first EcoDemonstrator flew to conduct various experiments. One of the experiments was a Regenerative Fuel Cell (RFC) system to compensate a demand-requirement gap separating the power in an aircraft system. The RFC comprises a Proton Exchange Membrane (PEM) Fuel Cell and Electrolyzer and other auxiliary components. Commercialization of this system requires restrictions of volume and mass for flight application. An important issue for PEM fuel cells is water management near the membrane. Compact PEM fuel cells require gravity-assisted water transport. This paper describes simplified cell channel paths to conduct numerical calculations to ascertain the effects of combined gas channels with an anode and cathode. The chosen parameters are a geometrical pattern and a flow rate (inflow velocity). Ion transport with water and a membrane water balance between the anode and cathode sides are simply incorporated. Although the calculations themselves do not include the gravity effect, the result suggests that a proper combination of the gas channels enhances proper water balance in the membrane. © 2016, American Institute of Aeronautics and Astronautics Inc, AIAA.

Due to the distinguished properties offered by different structural phases of monolayer MoS2, phase engineering design are urgently required for achieving switchable structural phase. Strain engineering is widely accepted as a clean and flexible method, however, can not be achieved in engineering monolayer MoS2 phase transition because the critical biaxial strain required (~15%) is much larger than measured elastic limit (~11%). In this study, employing density functional theoretical calculations, it has been found out that with the forming of heterostructure between MoS2 with buckled 2D materials such as silicence, germanene and stanene, only a small strain can trigger the phase transition. As being suggested by the constructed phase stability diagram, biaxial deformation as low as 3% in MoS2/silicene and MoS2/stanene sandwich structure, would be sufficient to induce the structural phase transition in MoS2 lattice. This strain falls well within experimental elastic limit, thus would be feasible to realize in experiment. The origin of such behavior can be understood as strain induced interlayer covalent bond formation, which finally make MoS2 lattice more sensitive to external strain. This theoretical work provides one realistic route for achieving flexible phase stabilities in experimental design. Copyright © 2017, The Authors. All rights reserved.

Dispersions of individual carbon nanotubes (CNTs) are crucial for nanodevices and polymer/CNTs nanocomposites. In this paper, stable and homogenous dispersions of individual multiwalled carbon nanotubes (MWCNTs) have been synthesized. The factors influencing the dispersibility mechanism, including the surfactant concentration and the pH value, have been investigated. SEM images display the impurities sticking on MWCNTs which have been removed. The oxygen-containing groups on the surface of MWCNTs sample have been detected through FT-IR and Raman spectra. All experimental results illustrate that using fullerenols as surfactant can greatly improve the dispersibility of MWCNTs. Moreover, the prepared dispersions exhibit good stability that the sediment percentage of fullerenols-MWCNTs is only 5.2% after 5 days.
