This paper constructs a scheduling method of an integrated production and delivery scheduling system based on Simulated Annealing approach. The system includes one distributor and one manufacturer with a single machine. The jobs are released at different times, and the goal is to minimize the sum of waiting punishment cost and delivery cost. The problem is NP-hard in the strong sense. To reduce the...
A single layer wideband SIW-fed differential patch array is proposed in this paper. A SIW-CPS-CMS (substrate integrated waveguide - coupled lines - coupled microstrip line) transition is designed and has a bandwidth of about 50%, covering the E-band and W-band. The differential phase deviation between the coupled microstrip lines is less than 7.5° within the operation band. A 1×4 array and a 4×4 array...
Full correlation matrix analysis (FCMA) is an unbiased approach for exhaustively studying interactions among brain regions in functional magnetic resonance imaging (fMRI) data from human participants. In order to answer neuroscientific questions efficiently, we are developing a closed-loop analysis system with FCMA on a cluster of nodes with Intel® Xeon Phi™ coprocessors. Here we propose several ideas...
Non-blind image deblurring algorithms based on the regularization can cause ringing artifacts. Using hyper-Laplacian priors, Krishnan D has proposed a non-blind deblurring model which can reduce ringing artifacts well, but it damages the image edge details. To solve this problem, a parameter adaptive non-blind deblurring model based on regional division is proposed in this paper. It can effectively...
Depth map, as important auxiliary information in 3D procession, is used to synthesize virtual view rather than exhibition. Inspired by this, a synthesis-guided depth super resolution (SGDSR) algorithm is proposed. Employing the synthesis error between virtual view and corresponding original one as the criteria, the best super-resolved result is selected among numerous candidate super resolution (SR)...
In real-time anomaly detection problems, reducing the dimensionality and improving recognition rate are two most crucial problems. The unbalanced data distribution is one of main reasons of leading to low recognition rate. In this paper, a hybrid approach using Tabu search (TS) and ensemble classification algorithm is proposed. Tabu search is simultaneously applied to select features and weights of...
In this paper, we present a saliency-aware image completion method which takes full advantage of a saliency detection result. On one hand, the saliency map is incorporated into the completion order computation procedure to take human visual attention into account. On the other hand, the saliency map used in patch matching makes the searched result more accurate and smooth. Furthermore, we employ an...
Human face recognition technology is one of the hottest research in the field of pattern recognition at present. In this paper, the principle component analysis (PCA) and bidirectional principle component analysis (BDPCA) methods are proposed to recognize a grayscale face image, for which the size of the spatial distribution is 64 × 64. At first, the main part of the face is extracted to form the...
In this paper, we propose a geometric algorithm for interpolating a given polygon using non-uniform cubic Bsplines. Geometric interpolation uses the given polygon as the initial shape of the control polygon of the B-spline and reduces the approximate error by iteratively updating the control points with the deviations from the corresponding interpolated vertices to their nearest foot points on the...
Successful percutaneous nephrolithotomy (PCNL) highly depends on an accurate needle access into the kidney. This step is challenging and must be performed under intraoperative image guidance. This paper presents a 3D augmented reality method for ultrasound (US)-guided percutaneous renal access in PCNL. First, a 3D statistical kidney model is built aforehand from aligned training shapes. Intraoperatively,...
Affected by various shortness shocks, the windings of transformer is loosening and deforming. As a result, power transformers' ability is decreased to withstand short circuit current and a big run accident is planted. Therefore, it is of great importance to conduct the research on the simulation test of winding especially wingding looseness of the power transformer. A method for power transformer...
Ferroelectric random access memory (FeRAM) is a promising candidate to substitute static random access memory (SRAM) in lookup table (LUT) design due to its high density, high speed operation, anti-radiation and non-volatility. Ferroelectric gate field effect transistors (FeFETs) have been extensively studied and its usage in memory elements and basic analog circuit configurations has gained much...
The usage of ferroelectric-gate field effect transistors (FeFET) in digital circuits typically involved that of memory applications, but the use of FeFET to implement logic circuits was not completely understood and had not been extensively studied. This paper presented the simulation of electrical properties of a single FeFET and the results of behavioral characterization of FeFET-based basic logic...
The ion and fluidic transport in the nanopore system is investigated via a multi-physical modeling of the electrostatic, nanofluidic and ion motion properties. We solve a series of coupled equations including Poisson, Navier-Stokes and Nernst-Plank descriptions for the system. We quantitatively investigate the relation between the induced electroosmotic flow in the presence of nanopore wall surface...
In this paper, we study the problem of data collection for monitoring traffic condition with compressed sensing (CS) in vehicular ad-hoc networks (VANETs). Unlike the conventional approaches, which require uniform sampling of the velocities of the vehicles, we propose a scheme that combines in-network data aggregation and compressed sensing technique based on random walk for data gathering in VANETs...
To suppress zero-sequence circulating current in parallel operating inverters with common DC power supply, this paper proposes a new strategy based on Dual-carrier SVPWM and proportional resonant (PR) control, which use two opposite active vectors instead of zero vectors to suppress the higher frequency circulating current and reduces the lower frequency circulating current by means of zero-sequence...
Various pulse width modulation strategies have been proposed to reduce the common mode voltage (CMV) in the variable speed motor drive system. However, unexpected voltage spikes appear as a result of the dead time effect. This paper investigates the principles of those reduced CMV PWM (RCMV PWM) methods mathematically and analyzes the reasons for those voltage spikes theoretically and experimentally...

Pulse width modulation (PWM) inverters have been widely used in the variable-speed motor drive. However, the common mode voltage (CMV) and common mode current (CMC) produced by PWM inverters cause EMI to electronic equipments around. This paper experimentally investigates the CMV/CMC characteristics of important reduced CMV PWM methods, such as active zero state PWM1 (AZSPWM1), near state PWM (NSPWM)...
