The theoretic ground of a locally topological method for defining a minimal attractor embedding dimension on the basis of linear and nonlinear decompositions in state-space of a dynamic system is proposed. The computer confirmation of the theoretical results is presented.
Plagiarism is known as illegal use of others' part of work or whole work as one's own in any field such as art, poetry, literature, cinema, research and other creative forms of study. Plagiarism is one of the important issues in academic and research fields and giving more concern in academic systems. The situation is even worse with the availability of ample resources on the web. This paper focuses...
Encoder circuits are vital component of an electronic computer system. Encoders are generally used for the conversion of a 2" bit number into the n bit number. Applications of encoders can be visualized as keyboard encoder on widespread use. Design of an optimized encoder circuit with the concept of reversible logic is the main outcome of this research paper. The concept of reversible logic has...
Semantic computing is an important task in the research of natural language processing. For the problem of the inaccurate conceptual graph matching, this paper proposed the algorithm based on Conceptual sub-Graph weight self-adjustment. Based on the in tensional logic model of Chinese concept connotation, using Recursive Conceptual Graph as knowledge representation method and combining with the computation...
First, the paper gives the definition of the strongly row (column) full rank matrix, the quasi-upper triangular matrix and the quasi-lower triangular matrix of the m × n matrix. Then the triangular factorization is generalized to the m × n matrix, and some factorization theorems are obtained. By using the triangular factorization, the linear equations with strongly row (column) full rank coefficient...
The physical process modeling of an estuary is a complex mechanism that comes along with the existence of uncertainty. In contrast, due to significant variability of flows in space and time, an extensive modeling effort must be accommodated with the application of parallelization technology. Therefore, the implication of estuary model parallelization to the model result uncertainty must be examined...
Mathematics education is an essential part of every engineering curriculum. The question of how much math should be included in an engineering curriculum is under discussion and the mathematics content has come under closer scrutiny with the aim of teaching engineers mathematical topics that have close practical relevance to their discipline at a time when those topics are most needed. This article...
In this paper an image processing algorithm for automatic evaluation of scanned examination sheets is described. The discussed image contains selected function graphs sketched on a prepared sheets. This type of task is characteristic of final high school exams of natural sciences. Our challenge was to develop an evaluation algorithm, which works with a precision comparable to the teacher. If the image...
Local stereo matching methods are still used widely because they are fast and simple. But the accuracy of local methods is much poorer than the global methods. They usually achieve accuracy at the expense of speed. Simple local methods are fast, but exhibit systematic errors. In this paper we propose an improved method based on support-weight approach, which can enhance the matching efficiency and...
Over the past few years, the relationship between attitudes and behavior has been of a major interest to educators. Previous studies have found varying degree of associations between attitudes, behavioral intention and perceptions and corroborate the fact that attitudes influence patterns of behavior. As computer technology is becoming pervasive in the society, researchers have attempted to explore...
In this paper, a new admission control scheme is presented based on the proportional admission control scheme of the IEEE802.11aa to solve the problems in the 802.11 WLANS. Quality of service (QoS) and throughput are the most significant questions in the 802.11 WLANS especially when the bandwidth is scare. In the Overlapping Basic Service Set (OBSS), we need to face many problems such as the high...
Communication is a vital part of computer systems today. One current problem is that computational capacity is growing faster than the bandwidth of interconnected computers. Maximising performance is a key objective for industries, both on new and existing software systems, which further extends the need for more powerful systems at the cost of additional communication. Our contribution is to let...
Numerical analysis is an important process for creating reliable numerical software. However, traditional analysis methods rely on manual estimation by numerical analysts, which is restricted by the problem size. Although some state-of-art software packages can check whether a program is numerical unstable, they cannot tell whether it is caused by ill-posed problem itself or by some improper implementation...
Given an incompletely specified index generation function, the number of variables to represent the function can often be reduced by properly assigning don't care values. In this paper, we derive a lower bound on the number of variables necessary to represent a given incompletely specified index generation function. We also derive three properties of incompletely specified index generation functions...
The design process for electromechanical devices is discussed and the roles played by the knowledge of the designer, experimental devices and physics based models in achieving an effective solution examined. The representation of the knowledge components in a computer based implementation of the process is considered and appropriate implementations are presented. The resulting system functions as...
In the present paper, computer empirical models of PV panels are developed in the Cadence PSpice environment. The model parameters are obtained from the datasheet characteristics. The model parameters are optimized using parametric analysis in order to increase the model accuracy.
Today it is necessary for every country to promote the sustainability of its supply chains. In the same context, this paper uses the Ecological Footprint tool into developing an evaluating process to estimate and improve the environmental performance of Tunisian supply chains. Several Ecological Footprint studies until today were focused on a national scale. However, this one examines the retailer's...
In this paper, an iterative algorithm is established for solving a class of matrix equations with complex unknowns. By using the hierarchical identification principle, the gradient-based iterative algorithms are constructed to solve the equation AXB + CXHD = F and the coupled equations A1XB1 + A2XHB2 = F1 and C1XD1 + C2XHD2 = F2. The the convergence factor is presented to guarantee that the iterative...
An optimized parallel algorithm is proposed to solve the problem occurred in the process of complicated backward substitution of cyclic reduction during solving tridiagonal linear systems. Adopting a hybrid parallel model, this algorithm combines the cyclic reduction method and the partition method. This hybrid algorithm has simple backward substitution on parallel computers comparing with the cyclic...
