摘要：

The short-term   hydrothermal scheduling (SHS) is a complicated nonlinear optimization problem   with a series of hydraulic and electric system constraints. This paper   presents a hybrid algorithm for solving SHS problem by combining real coded   genetic algorithm and artificial fish swarm algorithm (RCGA-AFSA), which   takes advantage of their complementary ability of global and local search for   optimal solution. Real coded genetic algorithm (RCGA) is applied as global   search, which can explore more promising solution spaces and give a good   direction to the global optimal region. Artificial fish swarm algorithm   (AFSA) is used as local search to obtain the final optimal solution for   improving the exploitation capability of algorithm. The water transport delay   between connected reservoirs is taken into account in this paper. Moreover,   new coarse and fine adjustment methods without any penalty factors and extra   parameters are proposed to deal with all equality and inequality constraints.   To verify the feasibility and effectiveness of RCGA-AFSA, the proposed method   is tested on two hydrothermal systems. Compared with other methods reported   in the literature, the simulation results obtained by hybrid RCGA-AFSA are   superior in fuel cost and computation time. (C) 2014 Elsevier Ltd.

摘要：

Reservoir flood   control operation is a complex engineering optimization problem with a large   number of constraints. In order to solve this problem, a chaotic particle   swarm optimization (CPSO) algorithm based on the improved logistic map is   presented, which uses the discharge flow process as the decision variables   combined with the death penalty function. According to the principle of   maximum eliminating flood peak, a novel flood control operation model has   been established with the goal of minimum standard deviation of the discharge   flow process. At the same time, a piecewise linear interpolation function   (PLIF) is applied to deal with the constraints for solving objective   function. The performance of the proposed model and method is evaluated on   two typical floods of Three Gorges reservoir. In comparison with existing   models and other algorithms, the proposed model and algorithm can generate   better solutions with the minimal flood peak discharge and the maximal   peak-clipping rate for reservoir flood control operation.

摘要：

This paper is   concerned with the two-mode-dependent filtering problem in networked control   systems (NCSs) where the random external input-to-filter delay and the   output-to-filter delay are modeled as Markov chains. The nonlinear   discrete-time system is modeled by the Takagi-Sugeno fuzzy model. The overall   filtering error system is formulated as a special jump linear system. Then   definitions of H-2 and H-infinity norms of the filtering error system are   proposed. Moreover, the two-mode-dependent H-2 and H-infinity filters are   designed to incorporate the external input-to-filter delay and the   output-to-filter delay using linear matrix inequality (LMI) techniques. The   simulations and a numerical example illustrate the feasibility and   effectiveness of the proposed method. (C) 2014 Elsevier Inc. All rights   reserved.

摘要：

Numerical   simulations have been carried out to investigate the heat transfer   enhancement for fluid flow in a pipe partially filled with porous media. The   new axisymmetric lattice Boltzmann model is used to calculate the fluid flow   and heat transfer characteristics in a pipe filled with porous media. The   proposed algorithm is implemented on the Graphics Processing Unit (GPU) using   NVIDIA's CUDA for a high calculating speed. Finally, the effects of several   parameters, such as porous layer thickness, Darcy number and porosity, on   thermal conductivity efficiency are investigated. It is found that   controlling the thickness of the porous media can significantly improve heat   transfer performance and the influence of porosity is very small both on flow   field and temperature field when other parameters are fixed.

摘要：

In order to   improve the comprehensive competitiveness of small- and medium-sized   enterprises (SMEs), a cloud manufacturing service platform for SMEs was implemented   with the idea and model of cloud manufacturing (CMfg) in this paper. Using   the transaction mode of multiple enterprises, multiple orders, and   multi-party collaboration, the architecture and workflows of this cloud   manufacturing service platform were designed. Some common engines, such as   intelligent matching engine for supply and demand, transaction coordinating   logic engine, and credit evaluation engine, were researched, which implement   the semantic intelligent searching, order tracking, transaction task guiding,   and collaborative management in the whole process of CMfg. As a case, this   platform has been applied in the automobile and motorcycle parts   manufacturing industry, which effectively integrates manufacturing service   resources in this field through online services and offline services (O2O),   achieving the effective management of service resources.

摘要：

In this paper, a   new entropy approach is developed to study the vulnerability of cluster   supply chain network during the cascading failure spread from a holistic   point of view. We use the tools of complex network theory and social network   analysis to obtain the network representation of cluster supply chain system   and explain its cascading phenomenon. Then we build a new cascading model for   cluster supply chain network, and further introduce the concept of network   load entropy, to analyse and predict the dynamic behaviours of the   vulnerability during the process of failure spreading. Using a cluster supply   chain network in an industrial district as a case study, we employ the   modelling approach to explore its vulnerability. The simulation results   demonstrate that the vulnerability of cluster supply chain network with   cascading failures can be identified and predicted efficiently by using the   modelling approach. In addition, this work may have practical implications   for reducing the cluster supply chain network vulnerability in the cascade   control and defence, then obtaining its healthy evolution.

摘要：

A thermal   elastohydrodynamic lubrication (TEHL) finite line contact model is developed   for a helical gear pair lubricated with an Eyring fluid or a power-law fluid   in order to investigate the effects of the working conditions. A lubrication   analysis within a meshing period shows that the differences between the   Eyring and Newtonian solutions mainly lie in the film temperature and the   shear stress. For the power-law fluid, the power index n has a significant   effect on the film thickness. The effects of load and speed on lubrication   performance along the line of action are discussed.

摘要：

An improved   quaternion switching filter for colour image denoising is presented. It   proposes a RGB colour image as a pure quaternion form and measures   differences between two colour pixels with the quaternion-based distance.   Further, in noise-detection, a two-stage detection method is proposed to   determine whether the current pixel is noise or not. The noisy pixels are   replaced by the vector median filter (VMF) output and the noise-free ones are   unchanged. Finally, we combine the advantages of quaternion-based switching   filter and non-local means filter to remove mixture noise. By comparing the   performance and computing time processing different images, the proposed   method has superior performance which not only provides the best noise   suppression results but also yields better image quality compared to other   widely used filters.

摘要：

High-level   radioactive waste is heat-emitting; the temperature can increase up to 100 °C   in the gallery, and thus increase the density of microcracks in the host rock   of argillite. In the meantime, the host rock undergoes swelling or shrinking   induced by wetting or drying during ventilation or sealing process.   Therefore, it is necessary to study the influence of temperature and water   content, as well as their coupling effects, on the mechanical behaviour of   argillite for the safety of underground disposal of high-level radioactive   waste. For this purpose, we performed classical triaxial compression tests,   micro-indentation tests and mini-compression tests on Callovo-Oxfordian (Cox)   argillite under both temperature-controlled and relative humidity-controlled   condition. Five levels of relative humidity (from 33 to 99%) and five levels   of temperature (from 20 to 95 °C) were studied. The evolutions of elastic   modulus, strength and deformability of Cox argillite were related to the   temperature and relative humidity. It is found that the mechanical properties   of Cox argillite were significantly deteriorated by the temperature and   relative humidity, as well as their coupling effects.

摘要：

Theoretical   prediction of adiabatic shear band spacing is beneficial to understand the   mechanism of the serrated chip formation. The momentum equation, energy   equation and compatibility equation in orthogonal cutting are established in   this paper. Using perturbation analysis by regarding cutting speed and uncut   chip thickness as basic disturbance, an analytical solution of adiabatic   shear band spacing is developed. Adiabatic shear band spacing of serrated   chip is related to the wave number of the perturbation when the growth rate   reaches to maximum. It is found that adiabatic shear band spacing decreases   with the increase of cutting speed but increases with uncut chip thickness.   The experiment of orthogonal cutting Ti6Al4V under different cutting speeds   (50 m/min-1800 m/min) and uncut chip thicknesses (0.02 mm-0.16 mm) verifies   the validity of the theoretical prediction.

摘要：

The workspace   measurement and positioning system is a three-dimensional (3-D) coordinate   system based on laser scanning, which is widely applied in large-scale   metrology. As a core part ensuring measurement accuracy, the transmitter   parameters' calibration is the critical technique of the system. The present   transmitter parameter calibration method relies on auxiliary measurement   equipment, which is more error prone and less efficient. This paper will   focus on the improvement of the transmitter parameters' calibration by using   a highly precise 3-D coordinate control network. Several calibration points   with known coordinates are set in the workspace to establish the precise 3-D   coordinate control network. After the new model of transmitter parameter   calibration has been explained, both the calculation method for optimization   and the production of the initial iteration value are given. As indicated by   the results of the verifying experiment, the accuracy and efficiency of the   transmitter calibration can be distinctly improved by using the proposed   method. The experimental data show that the 3-D coordinate measurement error   has obviously decreased from 0.3 to 0.15 mm as a merit of the proposed   method.

摘要：

Tuber   melanosporum is highly appreciated in culinary contexts due to its unique and   characteristic aroma. T. melanosporum fermentation has been established as a   promising alternative for fruiting bodies to produce volatile organic   compounds (VOCs). In this work, a technique using a combination of   chromatographic fingerprint similarity analysis, head-space solid phase   microextraction and gas chromatography was developed to rank the significance   of fermentation conditions on the VOCs profile during T. melanosporum   fermentation. Omission tests indicated that the absence of major carbon   source (i.e., sucrose) in the fermentation media had the most significant   effect on the profile of VOCs, followed by the absence of yeast extract or   peptone. Consideration of the culture conditions revealed that VOCs produced   was the most significantly affected by temperature. These results indicated   that it is possible to adjust the aroma of truffles via fermentation process   control.

摘要：

In offshore   environment, newly deposited quaternary loose sediments widely exist in the   world. Sometimes, coastal engineers cannot avoid choosing these natural loose   sediments as the foundation of marine structures. Under this situation, the   interaction between ocean wave, marine structures and their loose sand   foundation, and the wave-induced pore pressure built-up in loose seabed   foundation are the key factors in which coastal engineers would most concern.   In this study, the nonlinear interaction mechanism between ocean wave, a   composite breakwater and its loose elasto-plastic sand bed foundation is   investigated by utilizing a semi-coupled numerical model FSSI-CAS 2D. In the   coupled numerical model FSSI-CAS 20, VARANS equation for wave model, and   dynamic Blot's equation for soil model are used for the governing equations.   The advanced and excellent elasto-plastic constitutive model PZIII proposed   by Pastor et al. (1990) is adopted to describe the nonlinear dynamic behavior   of loose sand soil under cyclic wave loading. Taking the parameters of Neveda   sand determined in the VELACS project funded by NSF as the property   parameters for the loose sand bed, a small-scale computational case like the   experimental set-up in Mostafa et al. (1999) is taken as a representative   case to investigate the wave-structure-loose seabed foundation interaction   mechanism. The numerical results indicate that the pore pressure in loose   seabed foundation builts up significantly, and the marine structure subsides   and tilts under wave loading. The loose sand bed becomes denser and denser   due to soil compaction. Parametric studies show that both the wave   characteristics and the soil properties can affect the built-up of residual   pore pressure in loose seabed foundation. (C) 2014 Elsevier Ltd.

摘要：

This paper   proposes a flux control strategy for a consequent-pole permanent-magnet   (CPPM) machine that increases torque capability over a wide speed range and   enhances efficiency with a fast convergence. After a brief analysis of the   parameters of the CPPM machine, a new flux-weakening algorithm is proposed to   achieve maximum torque output over the entire speed range. The optimal flux   reference is determined by the preset output flux generated by the 1/omega   method and compensated by the voltage closed-loop controller to improve   dynamics response. A variable structure voltage controller incorporated with   a limiter is designed to generate the antiwindup control. Furthermore, the   loss model of the CPPM machine is derived to demonstrate that a 1-D search is   suitable for optimizing the machine's efficiency. Then, an adaptive flux step   search algorithm, which calculates the flux step proportional to the   derivative of the input power with respect to the q-axis voltage, is proposed   to minimize the power losses online. The experimental results are compared   with the traditional flux control strategy on a CPPM prototype machine, which   confirmed the robustness of the presented flux control strategy to obtain the   maximum torque output over the entire flux-weakening speed range. The   convergence speed is also increased in the efficiency optimization process.

摘要：

Mixed-model   assembly line sequencing is significant in reducing the production time and   overall cost of production. To improve production efficiency, a mathematical   model aiming simultaneously to minimize overtime, idle time and total set-up   costs is developed. To obtain high-quality and stable solutions, an advanced   scatter search approach is proposed. In the proposed algorithm, a new   diversification generation method based on a genetic algorithm is presented   to generate a set of potentially diverse and high-quality initial solutions.   Many methods, including reference set update, subset generation, solution combination   and improvement methods, are designed to maintain the diversification of   populations and to obtain high-quality ideal solutions. The proposed model   and algorithm are applied and validated in a case company. The results   indicate that the proposed advanced scatter search approach is significant   for mixed-model assembly line sequencing in this company.

摘要：

A noncontacting   combined measuring system comprising a nondiffracting beam attitude angle   sensor, laser rangefinder, and total station is proposed for the coordinate   measurement of hidden parts in large-scale spaces. The laser from the total   station is aimed at the retro-reflector of the attitude angle sensor to   obtain the spatial coordinates. Moreover, parts of the laser pass through the   retro-reflector and generate a nondiffracting beam spot on the charge-coupled   diode through an axicon lens. The horizontal angle of the attitude angle   sensor can be obtained by using center fitting of the nondiffracting beam   spot. An inclinometer can be used to obtain the rolling angle and the   pitching angle. The laser from the rangefinder is directed at the measured   point to measure the distance from the attitude angle sensor to the measured   point. Finally, the spatial coordinates of the measured point can be   calculated by using the measured spatial coordinates, the three attitude   angles, and the distance. The experimental results of the combined measuring   system are compared with those of the total station. The two results show   good agreement.

摘要：

Existing band   gap analysis is mostly focused on the binary structure, while the researches   on the quaternary layered periodic structure are still lacking. In this   paper, the unidimensional lumped-mass method in the phonic crystal theory is   firstly improved so that the material viscoelasticity can be taken into   consideration. Then, the binary layered periodic structure is converted into   a quaternary one and band gaps appear at low frequency range. Finally, the   effects of density, elastic modulus, damping ratio, and the thickness of   single material on the first band gap of the quaternary layered periodic   structure are analyzed after the algorithm is promoted. The research findings   show that effects of density, elastic modulus, and thickness of materials on   the first band gap are considerable but those of damping ratio are not so   distinct. This research provides theoretical bases for band gap design of the   quaternary layered periodic structure.

摘要：

Green   phosphorescent inverted hybrid inorganic-organic light-emitting diodes   (IHyLEDs) based on a simplified organic layer/WO3 structure have been   demonstrated. The WO3 layer enabled facile hole injection and transport,   which was balanced by efficient electron injection from the indium-tin-oxide   (ITO) cathode overcoated with nanometer-thick Ca. The IHyLEDs had a turn-on   voltage of 6 V. At 20 mA/cm(2), it reached a luminance of 8133 cd/m(2) and a   current efficiency of 40 cd/A, which were 43% higher than a similar IHyLED   with a conventional Al/LiF electron injection layer. The IHyLEDs with Ca also   exhibited improved reliability under constant-current stressing at 20   mA/cm(2).

摘要：

In 2009, Lee and   Chang proposed an electronic t-out-of-n lottery protocol over the Internet   based on the Chinese remainder theorem and blind signature. However, a   security flaw exists in Lee-Chang's protocol that the lottery agent and the   malicious purchaser can collude to control the winning result, which is   unfair for the honest participants. On the basis of a verifiable random   number generated by using the Lagrange interpolation formula over a finite   field, an improved t-out-of-n e-lottery protocol is proposed, which   guarantees that each participant can generate the winning result equally. The   improved protocol achieves public verifiability and fairness without a   trusted third party and a delaying function, which makes it more robust and   more efficient.

摘要：

The method of   retrieving atmospheric aerosol extinction coefficient from Raman lidar data   is analysed. The logarithm for the ratio of nitrogen molecules density to   distance correction signal is focused on and is discussed deeply. The   weighted least squares method is used to fit the discrete signals. The   weights are valued according to the kind of photomultiplier tube and its   detecting mode. The profiles of the atmosphere aerosol's extinction   coefficient are detected by Raman lidar at Wuhan, China. From the   distribution of the aerosols, the structure and the change of atmospheric   boundary layer arc showed clearly.

摘要：

Existing   multicast schemes always employ the scalable video coding (SVC) to   accommodate heterogeneous channel conditions. Although this method achieves a   high spectral efficiency, it will lead to serious quality imbalance problem,   i.e., the viewers who hold a better link conditions can obtain high video   quality, but the viewers with bad reception conditions can only receive the   video with poor quality. In this paper, we propose a novel Cognitive Radio   Assisted Quality Compensation (CRAQC) scheme for enhancing the video quality   of bad reception viewers. In CRAQC, the bad reception viewers can obtain from   the good reception viewers the video content they cannot receive directly   from the base station using cognitive relay links. One novel and promising   design of the proposed scheme is that it considers a cooperative transmission   style in relay process, in which viewers with the same relay content can   simultaneously broadcast this content in the same channel, and therefore   achieve the benefits of space diversity to the receiver. Through extensive   simulations, we demonstrate that CRAQC is able to significantly improve the   video performance of the bad reception viewers. (C) 2014 Elsevier B.V. All   rights reserved.

摘要：

The present   paper proposes a general framework for the description of short- and   long-term behavior of cement-based materials subjected to mechanical loading   and chemical degradation. The framework can take into account two different   damage mechanisms, mechanical damage and chemical damage, and their interaction   also can be considered. A special model is presented for the modeling of   leaching-mechanical coupling behavior of fiber-reinforced concrete. The   elastic modulus, Drucker-Prager-type criterion, and empirical evolution law   of creep strain are related to mechanical damage and chemical damage   variables. The evolution kinetic of mechanical damage caused by compression   and tensile stress are defined, respectively. The chemical damage is defined   with respect to the actual concentration of calcium in the solid skeleton,   which is calculated from the mass balance equation of calcium ions. The   diffusion coefficient is written as a positive function of mechanical damage   variable. The proposed model is implemented into COMSOL Multiphysics and   validated from decoupling experiments to fully coupling experiments to   progressively determine the model parameters. The proposed model offers an   adaptable framework to facilitate description of the chemomechanical coupling   behavior of cement-based materials.

摘要：

The multiconsensus   problem of double-integrator dynamic multiagent systems has been   investigated. Firstly, the dynamic multiconsensus, the static multiconsensus,   and the periodic multiconsensus are considered as three cases of   multiconsensus, respectively, in which the final multiconsensus convergence   states are established by using matrix analysis. Secondly, as for the   multiagent system with input delays, the maximal allowable upper bound of the   delays is obtained by employing Hopf bifurcation of delayed networks theory.   Finally, simulation results are presented to verify the theoretical analysis.

摘要：

This paper   presents two methods for dual-rate sampled-data nonlinear output-error   systems. One method is the missing output estimation based stochastic   gradient identification algorithm and the other method is the auxiliary model   based stochastic gradient identification algorithm. Different from the   polynomial transformation based identification methods, the two methods in   this paper can estimate the unknown parameters directly. A numerical example   is provided to confirm the effectiveness of the proposed methods.

摘要：

An encryption   scheme is a tuple of algorithms used to ensure secrecy while exchanging   messages over a public channel. Spatial encryption is a generalized extension   of id-based encryption with the ability of partial order role delegation. In   this paper, we propose an efficient spatial encryption with vector privacy   preservation, which is derived from the technique of static assumption from   dual system encryption in composite order groups. The proposed scheme   achieves the cryptosystem properties of message confidentiality, recipient   anonymity, adaptively full security, and short constant ciphertext. Provable   security in our setting consists of three steps: the first one is giving a   rigorous definition of security, the second one is giving the construction of   a scheme, and the last one is giving a rigorous mathematical proof showing   that the scheme satisfies the security definition given in the first stage.   Compared with related schemes, our proposed scheme has a comparable advantage   in security while it holds an approximate computing efficiency and   communicating payload such as public parameters, private keys, and   ciphertexts.

摘要：

The capability   of mesoporous activated carbons (MACs) to adsorb Cr (VI) in aqueous solution   was investigated. The MACs were prepared in the lab from upgraded coal tar   pitch using the nano-sized imprinting method. Adsorption of Cr (VI) was found   to be dependent on the solution pH. The adsorption kinetic data was found to   fit well with a pseudo-second-order rate equation. Three adsorption isotherm   models were used to analyse the equilibrium data. Removal of Cr (VI)   increased with an increase in mesoporosity of MACs, highlighting the   importance of mesoporosity in enhancing adsorption efficiency. The major   surface oxygen groups were carboxylic, lactonic and hydroxyl. X-ray   photoelectron spectroscopy analysis was employed to investigate the sorption   mechanism. It was revealed that a portion of Cr (VI) was adsorbed via   electrostatic interaction, while the rest was adsorbed in the reduced form   (Cr (III)) which was most likely bound to surface oxygen groups on the MAC.

摘要：

A speed sensor   fault-tolerant control (FTC) strategy for electric vehicle is proposed in   electric vehicles using a consequent-pole permanent-magnet (CPPM) machine. In   order to obtain good FTC performance at low speed region, a HF voltage   injection method is proposed to detect the rotor position from the magnetic   saliency. This magnetic saliency of a CPPM machine is analysed by the   finite-element analysis (FEA), and the high-frequency (HF) impedances are   measured to confirm the saliency. At high speed range, the   extended-electromotive force (EMF) method is applied when the failure of the   speed sensor is detected. The speed sensor FTC strategy is verified effective   by experimental results on a 25kW CPPM machine at different operating   conditions. The reliability is enhanced and smooth transition to the fault-tolerant   operation is realized.

摘要：

Binding   encryption provides an effective way to broadcast a secret to an authorized   group of users, which guarantees decryption consistency, i.e., that all users   can obtain the same message without any interaction among them. In this   paper, we first give the definition of security of a binding encryption, and   then construct a primitive that achieves security against chosen plaintext   attacks (CPA) and decryption consistency. This primitive is derived from a   CPA-secure public-key encryption (PKE) scheme. Then, we present several   transformations of binding encryption, which ensure some advanced security   requirements such as anonymity, strong decryption consistency, and   non-malleability.

(1) Negative   results that: (a) A CCA (chosen-ciphertext attack) secure PKE does not imply   a CCA-secure multi-receiver encryption (ME) or binding encryption; (b) an   anonymous CPA-secure PKE implies an anonymous ME but does not imply any   anonymous binding encryption; (c) a CCA-secure anonymous PKE does not imply a   CCA-secure anonymous ME or anonymous binding encryption.

(2) A generic   construction for a binding encryption that: (a) Uses CPA-secure PKE and   symmetric encryption to construct a CPA-secure ME; (b) uses a CPA-secure ME   and a polynomially verifiable function to construct a CPA-secure binding   encryption.

(3) Three   transformations from (anonymous) CCA-secure PKE to (anonymous) CCA-secure   binding encryption: the first one is based on a strong one-time signature,   the second one is derived from a trapdoor pseudo-random function, while the   third one is based on (information-theoretically secure) cover-free families,   and hence it does not require any additional computational assumptions.

摘要：

In order to   improve the transduction efficiency of electromagnetic acoustic transducer   (EMAT) for steel plates inspection, the constitutive equation of   magnetostrictive material was theoretically derived and simplified while the   magnetostrictive force is parallel to the material surface. Based on the   multiphysics field FEM, the effects of such excitation parameters as current,   frequency, and pulse number in AC coils on magnetostrictive strain were   mainly simulated, and the influence of the coil with different winding shapes   on magnetostrictive strain was also analyzed. The simulation and experimental   results indicate that magnetostrictive strain increases with a continuously   increasing excitation current density, but it decreases with the increase of   the frequency and pulse number of AC currents. Moreover, on condition that   loop length and AC currents are held constant, spiral type coils have higher   transduction efficiency than homocentric squares and figure-of-eight coils.

摘要：

Functional   encryption provides a general access control over the encrypted data, where   only the receiver with attribute (x) over right arrow that satisfies control   policy function f((v) over right arrow) of policy parameter (v) over right   arrow (i.e. f((v) over right arrow)((x) over right arrow) = 1) can decrypt   its cipher-text. Special cases of functional encryption include (anonymous-)   (hierarchical) identity-based encryption, fuzzy identity-based encryption,   attribute-based encryption, public key encryption with keyword search,   spatial encryption, inner-product encryption, hidden-vector encryption and   predicate encryption. In general functional encryption systems, the control   policy function can be set flexibly. The main gap among these functional   encryption schemes lies in the policy functions that associates with the   secret keys. In this work, we first investigate several functional encryption   schemes, and then formalize and unify the functionality description of the   control policies for these schemes. After giving a general definition and   security model, we present the relationship and transformations among   functional encryption schemes when the equivalence of these different policy   functions is employed.

摘要：

The purpose of   this study is to investigate the consensus problem of multiple flying   vehicles with random delays governed by a Markov chain. For second-order   system dynamics under the sampled-data setting, we convert the consensus   problem to the stability analysis of the equivalent error system dynamics. By   designing a suitable Lyapunov function and deriving a set of linear matrix   inequalities, we analyze the mean square stability of the error system   dynamics. Since the transition probabilities in a Markov chain are sometimes   partially unknown, we propose a method of estimating the delay for the next   sampling time instant. We explicitly give a lower bound of the probability   for the delay estimation which can ensure the stability of the error system   dynamics. Using an augmentation technique, we convert the random time-delay   discrete-time systems to delay-free stochastic systems. And then a sufficient   condition is given to guarantee the consensus of the networked multi-agent   system. Simulation studies for a fleet of unmanned flying vehicles verify the   theoretical results. (C) 2015 The Franklin Institute. Published by Elsevier   Ltd. All rights reserved.

摘要：

This paper   studies a regenerative cascaded multilevel converter that substitutes active   front ends for the diode-based front ends only in part of cells, and proposes   a power tracking control strategy that does not need any motor parameters.   During the induction motor's deceleration, by controlling the two kinds of   cells' output voltages according to the motor's power factor angle, the   converter makes the motor-generated energy wholly collected by regenerative   cells; thus, other cells' dc-link voltages remain stable. Regeneration   limitation is analyzed. The simulation results of a 6-kV six-cell cascaded   converter and experiments on a laboratory cascaded converter verify that the   converter can transfer the motor power back to the grid and allows the motor   to decelerate more quickly. Moreover, the control strategy is suitable for   the drive systems whose regenerated power cannot be estimated or is varying.

摘要：

In their quest   for greater sustainability, firms need to deal with many variables that   ultimately determine the selection of green technologies. Previous studies of   the possible link between the application of green technology and firm   performance have generally produced mixed results. Similarly, studies of the relationship   between environmentally friendly strategies and firm performance have also   been inconclusive. Based on an extensive empirical study, with 533   respondents from 98 firms in the Chinese manufacturing industry, we try to   identify the essential factors and test the links among variables in the   decision-making process for green technology selection. We use an integrated   structure equation model to test the complexity of a firm's technology   adoption. The relationships among the various variables are tested based on   empirical data from our questionnaire. More specifically, we measure the   influences on green technology selection imposed by task-oriented   circumstances (direct stakeholders, market environment, financial and social   dynamics) and macro-circumstances (legislation, social and technological   development phases, etc.). The results show significant relationships between   green technology selection and certain task-oriented circumstances and   macro-circumstances, which may facilitate proper action on the part of firms   with regard to green practices. Based on our findings, we present some   managerial implications and insights that might be useful for adopters of   green technologies and enhance environmental and overall performance. We also   discuss the limitations of our methodology at the end of the paper. (C) 2014   Elsevier Ltd. All rights reserved.

摘要：

An   invasive-attack-resistant physical unclonable function (PUF) with strong   reliability is presented. The mismatch of capacitor ratios in real   fabrication is sampled by a switched-capacitor (SC) circuit and further   amplified by a latch-styled sense amplifier. Transmission lines connected to   the sampling capacitors are used to cover and protect the whole chip from   outside invasive attacks. The proposed SC PUF is fabricated using HJ standard   0.18 mu m CMOS process. Simulation results show that the   invasive-attack-resistant sensitivity is less than 2.56 fF. The failed   outside invasive attack efforts verify the anti-invasive-attack property of   the PUF unit. Besides, measured results show that the proposed SC PUF circuit   with 3 V/1.8 V-VDD achieves an error rate 1x-5.5x lower than other PUF   implementations. An error correction block is also presented to achieve a   nearly zero error rate. The measured average error rate, bias, average   intra-die HD and average inter-die HD of the 3 V/1.8 V-VDD SC PUF with error   correction block is 0%, 46.72%, 0%, and 49.84% respectively.

摘要：

A temperature-dependent   model, combining optical elements and III-V multi-junction solar cells, is   proposed for the performance analysis of concentrator photovoltaic (CPV)   modules. Compared with the previous theoretical characterizing methods for   solar cells, our model takes into account the impact of the primary and   secondary optical elements in a realistic concentrator photovoltaic module by   ZEMAX modeling approach, making it possible to simulate the flux intensity   and spectral distribution on the active area of the solar cell according to   the practical direct normal irradiation. Then a two-diode equivalent circuit   semi-empirical model is presented to characterize the temperature-dependence   of the GaInP/GaInAs/Ge triple-junction cells used in the CPV module. The   circuit parameters are extracted by a synthetical approach, which combines   the global numerical optimization technique with the analytical extraction   method using the measured illuminated I-V characterization curve of the CPV   module at the determined condition and the temperature coefficients for short   circuit current and open circuit voltage of the triple-junction cell assembly   given in the product datasheet from the cell manufacturer. The   temperature-dependent performance of the CPV module analyzed by this model   agrees well with the measured results. (C) 2014 Elsevier Ltd. All rights   reserved.

摘要：

We have   demonstrated an original ultrafast laser beam shaping technique for material   processing using a spatial light modulator (SLM). Complicated and   time-consuming diffraction far-field phase hologram calculations based on   Fourier transformations are avoided, while simple and direct geometric masks   are used to shape the incident beam at diffraction near-field. Various beam   intensity shapes, such as square, triangle, ring and star, are obtained and   then reconstructed at the imaging plane of an f-theta lens. The size of the   shaped beam is approximately 20 mu m, which is comparable to the beam waist   at the focal plane. A polished stainless steel sample is machined by the   shaped beam at the imaging plane. The shape of the ablation footprint well   matches the beam shape. (C) 2015 Elsevier Ltd. All rights reserved.
