This paper focuses on the problem of designing H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> filters for nonlinear systems with time-varying delay via Takagi-Sugeno (T-S) fuzzy models. Some new results filter design are proposed by estimating upper bounds derivatives Lyapunov functionals without ignoring some useful terms, which improve existing ones. In addition, a sufficient condition existence such an is established in terms...

In some system identification problems, the weight vector to be estimated can represented by a tensor product of two low dimensional component vectors. This feature is useful for design adaptive filters with fast convergence rate and/or computational complexity. The LMS algorithm has been proposed under this scenario and its recent extensions find applications in several contexts. brief analyzes steady-state mean-square error (MSE) performance algorithm, which provide prediction guideline...

The existing classification methods for oil and gas exploration projects are imperfect their subjectivity in ranking, which hinders subsequent investment decision-making. This paper proposes a weighted multi-view collaborative fuzzy C-means clustering algorithm improved using the double-layer-nested particle swarm optimization (Double PSO-WCoFCM, or DPSO-WCoFCM short). cluster center of is optimized by combining standard WCoFCM algorithm. first PSO placed outer layer to optimize vector,...

Sparse system identification is often encountered in applications such as network and acoustic echo cancellation. This work applies the sparsity promoting method to affine projection algorithm (APA) develop a sparsity-promoting APA (SAPA). To reduce its computational complexity, gain matrix of SAPA periodically updated, which leads updated based (PSAPA). In addition, steady-state tracking performance PSAPA analyzed using an improved weighted energy conservation method, takes account...

Purpose Behaviour in virtual learning environments (VLE), including travel, gaze, manipulate, gesture and conversation, offer considerable information about the user's implicit interest. The purpose of this study is to find an approach for user interest mining via behaviour analysis a VLE. Design/methodology/approach According research psychology, any interaction VLE has implications In order mine interest, explicit interaction‐interest model needs be established. This paper presents...

The health of the aircraft's anti-skid braking system is critical to flight aircraft. failure brake will affect efficiency and safety. Therefore, this paper proposes an aircraft fault diagnosis method based on Grey Wolf Optimizer (GWO) Probabilistic Neural Networks (PNN). First, preprocess acquired data five parameters a certain type system: wheel speed, time, pressure, servo valve control current create PNN model. Aiming at shortcomings network smoothing factor selection experience, GWO...

Although the theories and methods about 3D GIS interactive editing are scarce primitive, need to develop them has become gradually urgent. For purpose of resolving it, in this paper, a method on geographic features visualization environment is proposed. By digital control surface, can deal with some geometric shapes effectively such as point, path, ring. Moreover, based OpenGL COM technologies, editor plug-in module form toolbar that be embedded ArcGIS developed. The practical results...

In present study, main structure working parameters affecting hole clogging situation were determined through theoretical analysis computational fluid dynamics simulations. addition, a three-factor, three-level quadratic regression orthogonal center...

Abstract In order to provide a comfortable working space in warm or hot environment, it is necessary cool these spaces consume energy. the context of global warming, ability comfort becoming more and challenging. With increase energy consumption, demand for cooling also increasing [1]. previous studies, different types individual local methods have been used reduce thermal stress outdoor workers [1-7] improve indoor office commercial buildings. Local can macro climate air temperature,...

A novel Hierarchical (H-) LU decomposition direct solution based on higher order basis function (HOBF) is presented to solve electromagnetic (EM) scattering from electrically large conducting targets. Due the H-matrix structure, H-LU fast solver can efficiently calculate inverse of a moment-method matrix. By utilizing high geometrical modeling, HOBF be defined. Therefore, number unknowns greatly reduced further expedite computation. Numerical results demonstrate that compared with low...
