Then we derive convergence estimate...

A parameter identification method for fractional order nonlinear systems was proposed. The basic idea is to use the Haar wavelets to represent the input and output signals, and then convert the nonlinear differential into a corresponding integral equation. As a result, the parameters of the nonlinear...

Scientific classification of land production functions can promote the efficient use of land. In this paper,16 land production functions were collected, and 10 characteristic features of land production function were put forward according to the different attributes of each function. The characteristics...

In this paper, a linearisation method for nonlinear ordinary differential equations based on coordinate basis transformation is proposed. In order to transform a nonlinear equation into a linear one, we introduce a general framework to extract the coordinate basis of the differential system. Actually,...

This paper investigates a continuous-time mean-variance portfolio selection problem with Ho-Lee stochastic interest rates. Compared with the mean-variance model with deterministic interest rate, a verification theorem without the classical Lipschitz and growth conditions is required to solve our portfolio...

This paper proposes an application of surface elasticity theory in the analysis of contact problem at nano-scale. The Fourier integral transform method is adopted to derive the fundamental solutions for contact problem with surface tension effects. As a special case, the deformation induced by normal...

Algebraic multigrid is often used as the preconditioner in Krylov subspace iterations to solve general sparse linear systems, and the aggregation based version is one of the most popular, for its cheap complexity to setup. In this paper, when this version used as the preconditioner, two schemes are provided...

In this paper, parametric excitation is applied to the excitation of a micro-ring gyroscope. The primary objective of this work is to improve the dynamic gain. It is show that, by adjusting the parametric excitation parameters, the harmonic forcing can be reduced whilst the gain of frequency response...

In this paper, we introduce a split general mixed variational inequality problem, which is a natural extension of a split variational inequality problem, split general quasi-variational inequality problem in Hilbert spaces. Using the resolvent operator technique, we propose two classes of perturbed iterative...

The image sequence of Vehicle panorama camera platform has the characteristics of serious distortion, large parallax and large amount of data, which can lead to invalid montage for the image sequence by adopting the common image mosaicking method based on features. In this paper, Voronoi algorithm is...

In order to develop a new hearing loss detection method, this paper proposed to combine wavelet entropy with feedforward neural network trained by genetic algorithm. The dataset contains 72 subjects—24 healthy controls, 24 left-sided hearing loss patients, and 24 right-sided hearing loss patients. The...

The Automatic Dependent Surveillance-Broadcast (ADS-B) with the advantage of faster update speed of the data, wider range of detection and sharing of traffic information. It has been regarded as one of the future mainstream surveillance systems by the International Civil Aviation Organization. This paper...

According to the SURF feature matching dense matching interpolation algorithm to realize the problems in the complex dynamic background image. The dynamic camera captured the same environment as the object. SURF image is proposed based on the combination of region and the feature information matching...

Facing the unbalance drop of three-phase grid voltage, jumping frequency and other complex working conditions, the accuracy and dynamic response of phase-locked loop (PLL) have become the important performance indicators of the photovoltaic grid-connected inverter. Aiming at the problem that the low...

We describe a program learns to follow directions using a corpus, without human preprocessing. The program only build a semantic lexicon instead of semantic grammar to learn from an untagged corpus. Without grammar, the program uses a language-independent parser to find the boundaries between steps,...

With the development of online information resource, open data sources are becoming an important channel for domain knowledge acquisition. To establish a comprehensive knowledge base of TCM, this paper choses Baidu Encyclopedia as data source by comparing the data and web structure of the main open TCM...

Human-computer interaction, which involves interactive information processing, directly affects the vividness and immersion of virtual operation. Therefore, this paper aims to achieve the naturalization and intelligence of human-computer interaction. We present two language understanding models constructed...

The shape of red blood cell is a primary factor for its deformability and filterability. Generally the regular shape of red blood cells should look like a biconcave disk. Meanwhile the deformability degradation of erythrocyte could lead to some blood-related diseases. Thus the shape analysis of red blood...

High throughput omics profiling technologies enable comprehensive and accurate measurement of plant physiology. However, currently, most high-throughput results are only used for discovery of individual significantly changed genes. High-level coordination of physiological mechanisms is rarely discovered...

With the progress of science and technology, a large number of waste electrical and electronic equipment (WEEE) not only poses a threat to the environment, but also causes serious waste of resources. It's necessary and practically significant for the governments environmental regulation to construct...

Cloud computing is generally considered to be beneficial for the public and private IT organizations because it can substantially reduce the cost of IT systems. Cloud computing technology is not only very important for the development of businesses but also has significant impact on the overall competitiveness...

The purpose of this study was to describe the 3-D nano-scaled surface texture of the Nickel–Carbon (Ni–C) nanocomposite thin films composed of Ni nanoparticles with different average sizes embedded in amorphous hydrogenated carbon using stereometric analysis.

Locating diffusion source in network is an important issue in network data analysis. Many methods have been developed. However, noiseless assumption used in the literature is restrictive and the methods are not robust enough. In this paper, we consider the problem of locating diffusion source in networks...

We define an evaluation metric, known as Smart Growth Metric, to judge whether the development of cities from around the world meets smart growth, which means the higher Smart Growth Metric is, the deeper the extent of urban smart growth is. As regards of the selection of evaluation index, referred to...
