Trust has been a hotspot for adopting cloud computing. This paper proposes a hybrid model to build, evaluate and expose trust. It uses different techniques like sliding window technique to reach optimum processes for trust value delivery. Trust value is evaluated through integrated mechanisms from literature. Moreover, measuring trust included evaluating SLA violations side to side with consumer customized...
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...
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...
With the widely used of augmented reality, we designed a remote chess game system based on augmented reality. It has the potential significance. The system can make two people both living in different places to play chess as they are playing face to face and can communicate with each other. In this paper, we make an introduction to the recognition and the positioning of the check board in detail....
Statics is the foundation course upon which much of the Civil and Mechanical Engineering curriculum is based. A solid understanding in this course can help to propel students through their engineering studies. In this paper, we investigate the performance of students who took part in a “flipped” mastery based engineering Statics course. Compared to the tradition classroom, where students can pass...
Orchestrator has found applications in integration of software services. An Orchestrator is like a coordinator. It provides controlled computation at parallel and sequential computational nodes. Many computational problems need the solutions of simultaneous equations which have large number of coefficients. This paper presents a novel application of an Orchestrator Framework to find faster solution...
The linearization of the differential equations is always the important work in the study of partial differential equations. In this paper, a necessary and sufficient condition is established for the existence of a 1-1 transformation of a system of nonlinear differential equations to a system of linear equations is shown with some examples including Burgers' equation and the Liouville equation.
Hybrid Bond Graph (HBG) is a bond graph-based modeling approach which provides an effective tool not only for dynamic modeling but also for fault detection and isolation (FDI) of switching systems. Efficient algorithms exist for fault detection and isolation based on functional redundancy. In a qualitative approach, this redundancy can be captured by a temporal causal graph (TCG), a directed graph...
The L_2-norm method is often used in the multi-degree reduction problem of Bezier curves, which achieves an approximation order of m+1 by using polynomials of degree m. This paper presents a tangent method for achieving a higher approximation order, in which a system of linear equations in the unknown control points of the resulting approximation Bezier curve is derived. Given the degrees of the given...
The modest aim of this reflection is to offer some illustrations of from-interpretation-to-improvisation process results. They have arisen from computer graphics approach to elementary mathematics education in technological university. Some of these outcomes (synographs) are - on the author's best known - of an original viewpoint nature.
In our contribution we would like to show how is possible to use GeoGebra in some historical — mathematical textbook. We show some examples from the textbook Václav Posejpal: Aritmetika pre ústavy učitel'ské (Arithmetic for Teachers' Institutes) with using GeoGebra. This textbook is from Library of Teachers Academy in Spišská Kapitula and we have Slovak translations from this textbook, which was made...
In order to solve the parallel algorithm for Petri nets system with concurrent function, to realize the parallel control and execution of the Petri nets, the Petri nets parallel subnets conditions were proposed, that provides the theory basis for judging P- invariant whether was the parallel subnet. Firstly, we according to the concurrent character of Petri net model, to analyze the parallelism of...
Camera calibration technique has important research and application value in the field of computer vision, and its precision directly affects the three-dimensional reconstruction effect. This paper elaborated the principles of the existing camera calibration methods: traditional camera calibration method, camera self-calibration method, and camera calibration method Based on active vision, and analyzed...
Reactive oxygen and nitrogen species (RONS) are desired in numerous applications from the destruction of harmful proteins and bacteria for sterilization in the medical field to taking advantage of the metastable characteristics of O2(1 Δ) to transfer energy to other species. Advances in atmospheric pressure plasma jets in recent years have shown the possibility of using this technology as a source...
Because attribute transfer causes element transfer, this paper gives the characteristic of information granulation in P-sets, and applies it in the image restoration. The experimental results indicate that this method can improve the performance and efficiency of image restoration, and that the algorithm is of great value in applications.
A kind of alpha-beta search algorithm based on region-divided checkerboard for the game of Amazons was used to improve the efficiency. Hierarchy searching is adopted in this approach. Searching is firstly carried in the divided regions, then the searching result of the whole checkerboard is gotten according to those valued of various regions. The evaluation and integration of divided regions are also...
In this study, we test anomaly based Denial of Service (DoS) detection approaches on networks with different utilization profiles. In the experiments, we use operational background traffic and performed Distributed DoS attackswithout disturbing the operational network. Experiment results indicate that the detection approach's detection performance is inversely proportional to network utilization and...
