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...
This paper presents a novel approach for fast reconstruction of corrupted images and videos. It is expected that corrupted pixels are known and identified. The presented approach is based on a radial basis function interpolation from neighbouring uncorrupted pixels. The proposed algorithm is simple, easy to implement and extensible to higher dimension as well. Algorithm speed-up is mostly due to the...
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...
The current UPnP service discovery algorithm in the presence of the service can cause severe drops in the digital home network. The reason is that the root devices instantly send delay sending response messages and randomly select independent response message congestion through simulation analysis. To solve these problems, an improved UPnP service discovery algorithm was given. Considering the length...
It is no coincidence that distance learning platforms are increasingly used in universities, colleges and companies seeking effective and continuous training of their employees without constraint of time and space. The effectiveness of such a learning system depends mainly on the degree of information assimilated by the learner at the end of training. In this article, we focus on the implementation...
In this paper, we first introduce the current teaching status of Algebraic courses including Linear Algebra and Abstract Algebra in Wuyi University; then we share our idea with some examples incorporating mathematical modeling arts into Algebraic courses; finally we list some nice consequences from this courses reform.
In this paper we present a way of introducing innovation in the teaching process by applying new teaching methods that are based on the principles of active learning and mathematical modelling, empowered by computers and mathematical software GeoGebra.
In this paper we concentrate on the field of mathematics education where the aim is to generate exercises going beyond those with answers of simple types (e.g. multiple-choice, Boolean, integer, or file comparison). We present three examples from introductory college mathematics and emphasize the key points that should be taken into account in order to develop a “well-posed” exercise together with...
In nature, predators and preys often form groups to perform chase and escape. We mathematically describe such a group chase and escape phenomenon by a cellular automaton. In this paper, by using numerical simulations of a cellular automaton with honeycomb grid, we discuss a method of group chase and escape. In particular, we compare several methods with the randomness of behaviour of the chasers....
Along with the boom of information, it is an important task to summarize the valuable information of opinionated texts. Firstly, we model the opinionated text by TAM and get the topic and aspect attribute of every sentence. Secondly, we successively used the basic LexRank, Comparative LexRank, Topic-sensitive tf*idf LexRank and Topic-sensitive tf*idf & Comparative LexRank to generate summary....
This paper presents our ongoing efforts toward developing an Intelligent Tutoring System (ITS) to improve student learning in a sophomore engineering dynamics course. An ITS module was developed to guide students applying the Principle of Work and Energy to solve particle dynamics problems. Pre-post tests, each including six technical questions, were administrated to 74 engineering undergraduates...
The present research study aims at detecting and recording Upper Secondary School students' criteria regarding the suitability of various calculating packages — including one specially designed and developed by the researchers- to assist teaching and problem solving electrical circuits. For the above purposes 69 Upper Secondary School students aged from 16 to 17 (male and female), after having undergone...
This study aims to identify the preliminary results of an integrated model for increasing professional education and schooling, besides to minimize structural deficiencies in basic subjects of exact sciences and to improve students assessments. The proposed model is based on the idea of formative itinerary and allows to: a) identify and handle students former educational deficiencies in basic subjects,...
Genes acquire many changes and modifications during evolution producing many orthologous and paralogous. One of the main challenges for biologist is tracing back the origin of modified genes in the genomes of various organisms. Tracing genes modifications and developments from the ancestors to offsprings is however a massive task for biologists. Thus, computer programs can help biologists tracking...
In the course of textbook management, we should make the leavings of textbook in the warehouse to remain as minimum as possible in order to reduce the unnecessary loss. In this paper, Boolean optimization model of this problem is established, and the machinery algorithm is given. Thereby the optimum strategy of handing out textbook is realized.
The aim of this study is to develop a diagnostic system for mathematical concepts. By adopting a Bayesian network for its high recognition rate in artificial intelligence and diagnosis, and combining and applying deduction methods in computerized tests, this system helps students to understand the difficulties they encounter in mathematical learning, and subsequently helps in implementing immediate...
The purpose of this study is to find out the effect of e-sports participation on self-confidence and social development of mentally retarded students. To collect the data, retarded male students between and old were tested. They attend a special-education school located in Ha- am, young- i and they too part in the test for times. The test is about the e-sports(FIF) and during wee s, from January th...
