The problem of electricity market dispatch is a multi-objective optimization problem. Based on the traditional Weighted method and Ideal point method, a new method is proposed in this paper, and a case was calculated. Compared with the date in literature, we know the relative error is less than 5%, so this method is effective. In order to get a comprehensive understanding of this method, uncertain...

The earliness/tardiness (E/T) case of Hybrid Flow-shop Scheduling problem (HFSP) is an NP hard problem, which is difficult to deal with, however, the local assignment existing in the practical production increases the complexity of this problem. How to solve the combinatorial optimization problem effectively and optimally is still an open issue today. In this paper, differential evolution algorith... View full abstract»

Self-regulating polymer heating cables are widely used in industry and the commercial world. Their applications include process temperature maintenance, frost heave protection, floor heating, and snow-melting. The heating cables automatically adjust their power output to compensate for temperature changes. This paper demonstrates a numerical approach based on a 3D finite element model to evaluate ...

In the laser enhanced gas metal arc welding (GMAW) process developed recently, droplets of melted metal can be detached from the wire under relatively low currents with the assistance of an auxiliary force provided by a laser. The stability and the arc and the quality of the resultant welds are improved. To compete with the gas tungsten arc welding (GTAW) of the much lower productivity in joining ... View full abstract»

Virtual test (VT) is broadly used in great systems which feature high-complexity and high-cost. Whether VT data can be accepted is determined by credibility of the models. The main approach of credibility check is test and evaluation (T&E), which is validating the consistency of models with animated entities via specific criteria. The underwater unmanned vehicle (UUV) virtual test is introduce... View full abstract»

The operation mode of the locomotive micro-devices is a combination of moving forwards, backwards, staying and rotation. In order to supply power by inductively wireless transmission to locomotive micro-devices, the micro-power receiver is often attached with the locomotive device. The distance and orientation between micro-power receiver and magnetic flux transmitter are changed as the locomotive... View full abstract»

There are mainly two classes of approaches in power disaggregation, including Intrusive Load Monitoring (ILM) and Nonintrusive Load Monitoring (NILM). This paper presents the literature review on the NILM approaches. NILM is a process for detecting changes in the voltage and current going through a house, deducing what appliances are used in the house, as well as their individual energy consumptio...

Based on the finite element analysis with centered finite difference, this paper focuses on 3-D analysis of three kinds of shaped charge penetrating to concrete. The process of forming penetrators is depicted in the test together with the process of penetration, which shows that under the same condition of diameter, the one with higher axis can form the rod-shaped penetrator with high velocity, la...

Investigating the linear placed cartridge Dynamite Explosion on different positions at the same depth in the water in the course of the study. And got the local displacement of ship plate and local stress and strai... View full abstract»

Mean Value Engine Models (MVEM) model the averaged dynamics of an automobile engine and have been used for the purpose of automotive control and fault diagnosis. Within-Cycle, Crank-Angle based Models (WCCM) are complex models that model the instantaneous dynamics of engine states and replace a real engine for simulation purposes. A WCCM was constructed on the simulation platform AMESim™. A... View full abstract»

A novel fault detection and diagnosis method based on kernel generalized discriminant analysis (kernel GDA, KGDA) is proposed in order to solve the problem of turbine fault detection and diagnosis. Through kernel GDA, the data is mapped from original space to the high-dimensional feature space. Then the statistic distance between normal data and test data is constructed to detect whether a fault i... View full abstract»

On the basis of introducing the model of Frequency-Domain Blind Deconvolution (FDBD), key techniques in mechanical signal extraction were comprehensively related and analyzed in this paper, which include the methods of suppressing the difference between circular and partial convolution by coordinating the relationship between FFT size and length of each frequency bin or Modified Discrete Fourier T...

Pattern processing exists in various fields like image processing and expert systems. Focus has been put on to high dimensional pattern processing, where there is a big concern of the system performance due to the high dimensionality. In the field of fuzzy inference systems, an exponential explosion in the required computational time complexity is caused by the multi variables in the input pattern... View full abstract»

In this paper, a novel data-driven approach is presented to monitor processes influenced by gradual small shifts. The primary idea is to first build multivariate exponentially weighted moving average (MEWMA) model based on the originally measured variables to keep the memory effect of the process trend. Then introduce a unified Mahalanobis distance based monitoring statistic, which makes full use ... View full abstract»

An actuator fault diagnosis approach is presented in this paper for a class of time-delayed nonlinear systems via the use of adaptive updating rules. The considered system is represented by a time delayed dynamical state space model where the time delays are embedded in the state vector. The linear part of the system is subjected to dynamical model uncertainties. Fault diagnosis observer is establ... View full abstract»
