In this paper, a quick and accurate detection method is discussed. It can identify whether the meat contain excessive moisture. By using near-infrared spectroscopy measurement, the meat moisture content model has been established. In order to improve the accuracy of the near infrared (NIR) measurement predicted model and to reduce the measurement sensitivity, we utilized the hyperspectral image information...
For manned drive for the rubber tram to track virtual tracks can easily lead to driver fatigue problems, on the basis of the visual navigation, an automatic steering control method based on the model predictive control is proposed. In the paper, Firstly, the automatic steering control principle based on visual navigation vehicle is introduced; then, the automatic steering predictive controller is...
Systematic principal component analysis (PCA) methods are presented in this paper for reliable islanding detection for power systems with significant penetration of distributed generations (DGs), where synchrophasors, recorded by phasor measurement units, are used for system monitoring. Existing islanding detection methods, such as rate-of-change-of-frequency and vector shift are fast for processing...
This paper presents a double-ladders circuit model of transformer winding for use in frequency response analysis (FRA) to diagnose the windings deformation. This model considers the nonlinear behavior of frequency-dependent parameter and core loss. A lumped parameter circuit model includes the axial and radial ladder network which are regarding to the winding discs and the eddy current paths of magnetic...
High temperature superconducting (HTS) cables for large current transmission in general have a multilayer structure consisting of parallel connected tapes, twisted in each layer. The control of current distribution among these layers is an important issue for design and optimization of a HTS cable because this would significantly affect the current transmission capacity and power losses. The pinned...
In this paper, based on Lyapunov-Krasovskii functional approach and the decentralized control theory of interconnected systems, we consider the observer-based control design for a class of fuzzy descriptor interconnected systems. Firstly, the stability conditions of the T-S fuzzy model with a prescribed performance level are provided in theorem 1, but there is no efficient algorithm solving the inequalities...
An accurate numerical procedure for analyses of transient scattering by two-dimensional dielectric objects by using the Time Domain Integral Equation (TDIE) method based on PMCHWT equations and Muller equations is developed. The Marching On-in Time (MOT) scheme is employed to solve the integral equations. Quadratic B-spline function is used as the temporal basis functions, and closed-form integrals...
The objectives of the research are to develop a novel balancing approach for a novel SAMS model which is called cart-seesaw system. The investigation is using fuzzy logic rule incorporates fuzzy coordinator compensation to drive the sliding carts and keep the seesaw angle close to zero in the equilibrium state. Experimental results indicate that utilizing the proposed control methodology significantly...
The nonlinear oscillations and chaotic dynamics are studied for a simply-supported symmetric cross-ply composite laminated rectangular thin plate with parametric and forcing excitations. Based on the Reddy's third-order shear deformation plate theory and the von Karman type equation, the nonlinear governing partial differential equations of motion for the composite laminated rectangular thin plate...
In this study, freshness changes and shelf life prediction of cultured tilapia (Oreochromis niloticus) stored at 0, 5 and 10°C were investigated. Total viable counts (TVC), the count of Pseudomonas spp. and total volatile basic nitrogen(TVB-N) in newly-caught tilapia were determined as 4.79±0.60 log cfu/g, 4.00±0.75 log cfu/g and 8.08±0.46 mg/100 g, respectively. At the end of shelf life, TVC, the...
