Using the cone theory, the existence and uniqueness of solutions for a class of systems of abstract binary operator equations in Banach space are discussed, and the error estimations for the convergent iterative sequence are given. The results presented here generalize and unify some known results.
In this study, single-phase quasi Z-source AC-AC converter with a series connection of the output terminals is proposed. The proposed system has configuration that the input terminals of two single-phase quasi Z-source AC-AC converters are connected in parallel and their output terminals are connected in series. The proposed system can perform the in-phase and out-of-phase buck-boost voltage modes...
Research and utilization of quadrotor helicopter in many areas is increasing because of its special flight performance. It is not easy to control a quadrotor whose dynamic characteristics are nonlinear, multivariable and stronglycoupled. A novel method is proposed to solve this problem, which adopts a MIMO RBF-ARX model to represent the nonlinear dynamics of quadrotor, and then based on a locally...
In this paper, we established some existence and uniqueness results for the fractional differential equations with nonlocal conditions. Our methods are based on the equivalent norm techniques and fixed point theorem.
There are numerical fractional differential equations models in the fields of signal and image processing. In this paper, we show some new existence and uniqueness results for the fractional differential equations with delay and impulse effects. Our methods is based on the equivalent norm techniques and fixed point theorem. An illustrative example is presented in the last section.
This paper has introduced the theory of precedents and method of representations into an topographical investigation of ecological potentials in Chinese Fengshui.. Firstly, it has briefly reviewed the theory of precedents and method of representations. Then it has started from these methods to transit an important design precedent: `Fengshui', into topographical representation as one case to investigate...
Grain logistics vehicle routing problem is derived from vehicle routing problem, they have been a focus of research in the grain logistics managements recently, which the aim is to use the limited vehicles to a large number of jobs so that the maximum number of jobs can be completed with minimum cost. Aiming at the characteristics of the large batch and multi-point to multi-point transportation of...
This paper deals with the dynamic manipulability and dynamic optimization of a redundantly actuated three degree-of-freedom (DOF) parallel manipulator. The dynamic formulation is derived based on the virtual work principle. The reciprocal of the condition number of the inertia matrix is presented as an index to evaluate the dynamic manipulability of the manipulator. Furthermore, a global dynamic conditioning...
When the Kalman-Yakubovich matrix has a unique solution, in this note an explicit solution is proposed. This solution is expressed as a polynomial of the coefficient matrices of the matrix equation. Based on this result, the unique solution of the Stein equation is also established. The proposed approach does not require the coefficient matrices to be in arbitrary canonical form.
Classification of the numerical data is a very important research topic in machine learning. But the incomplete data is very common in real world application. And the existence of incomplete data degrades the learning quality of classification models. But the existence of incomplete data always decrease the quality of classification models, To show the definition of missing data more intuitively,...
