Semi-Supervised Classification (SSC), which makes use of both labeled and unlabeled data to determine classification borders in feature space, has great advantages in extracting classification information from mass data. In this paper, a novel SSC method is proposed based on Remote Sensing Image character, which utilizes both spacial and spectrum feature relationship between labeled and unlabeled...
FES cycling is a safe and easy way for the rehabilitation of spinal cord injury (SCI) patients. In order to design an control system for FES cycling, this paper presents a control strategy of the cycling induced by FES. The control system is developed based on artificial neural networks and consists of two layers: the outer layer controls the FES cycling model dynamics and generates desired torque;...
This paper mainly focuses on the trajectory tracking control of a lower extremity rehabilitation robot during passive training process of patients. Firstly, a mathematical model of the rehabilitation robot is introduced by using Lagrangian analysis. Then, a model based computed-torque control scheme is designed to control the constrained four-link robot (with patient's foot fixed on robot's end-effector)...
Based on the mathematical model of wet clutch engagement, a dynamic model of a tracked vehicle was developed by means of the software Matlab/Simulink. This model can be used to simulate the shift schedule, piston pressure and relative velocity. A two dimensional heat conduction model was also developed with reasonable selection of proper boundary conditions, contact pressure model and heat flux distribution...
In this paper, we propose a reduced molecular network of the photosynthetic carbon metabolism, which includes the nine major metabolites with 48 parameters. The reduced molecular network can represent the key ingredients of photosynthetic carbon metabolism, i.e. the autocatalytic cycle, the utilization of photosynthate, and the effect of photorespiration. Based on the model, we theoretically study...
The objective of this study is to assess the environmentally friendly Ni(II) adsorption from synthetic wastewater using extracellular biopolymer(PS-2) produced by Pseudomonas fluorescence C-2. The ability of PS-2 to remove the Ni(II) ions was investigated by using batch biosorption procedure. The effects such as pH, dosage of biosorbent, Ni(II) initial concentration and sorbate-sorbent contact time...
This paper presents a scientific strategy for cycling induced by the functional electrical stimulation. In order to simulate the FES-cycling movement produced by human body, a neuro-musculo-skeletal model containing 16 segments and 186 muscles is developed, which can simulate human movements precisely. This model contains mathematical model of electrically stimulated skeletal muscles. Having known...
It has been observed in recent years that in many applications service time demands are highly variable. Without foreknowledge of exact service times of individual jobs, processor sharing is an effective theoretical strategy for handling such demands. In practice, however, processor sharing must be implemented by time-slicing with a round-robin discipline. In this paper, we investigate how round-robin...
Mathematical models play an important role in the studies of modern economics. But in many fields of economics, it is difficult to build mathematical models for complex phenomena. So data mining is getting more and more popular in discovering the potential pattern of economic knowledge from databases. As a powerful tool for data mining, rough set theory has been widely used. In this research, we draw...
Small impedance branches may lead to divergence of power flow. The convergence of power flow can be improved by some methods, such as improving voltage start, improving the Jacobian matrix, and using fast decoupled power flow. This paper investigates these methods, and finds out that when these methods are applied to systems with small impedance branches, they possess same characteristic, that is...
From investigating the relationship of the size of regional foreign direct invest (FDI) to their accessibility to the main seaports by railway or highway, it is proved that the logistics play a significant impact on regional industry competition. From the point of modern logistics view, the basic regional logistics service system constitutes the fundamental environment of investment. The concept of...
According to the characters of CE signal, improved wavelet thresholding with translation invariant was described to denoise for microchip capillary electrophoresis in this paper. The improved thresholding function has muti-derivative compared with the soft thresholding. The denoising method can not only remain the geometrical characteristics and keep the amplitudes of the original electrophoresis...
3D reconstruction has a long history, few workable reconstruction systems are available although many magnificent theories and algorithms are reported in literature. In this paper, a 3D reconstruction system for indoor scenes with a rotating platform is reported, including its key components such as system calibration, feature matching and 3D reconstruction. Experimental results show that this system...
The neighborhood structure of a pixel in an image can be described more accurately by its two principal curvatures than its gradient or mean curvature-based estimation. Based on this idea, we propose a novel method - minimum principal curvature-driven diffusion, in which the two principal curvatures are used in a curvature-driven diffusion equation for image filtering. The main advantage of the proposed...
