Internet technology developed fast in recent years, it provided more mature development environment for e-learning. E-learning technologies have been widely used in private business or school, it usually through a CAI system which has been established completely, then can make learners freely use after classes on the network platform. Web-based learning is a technology-mediated learning that learners...
In order to obtain the development and change of teachers' levels of reflection in teachers' online community of practice (TOCP), content analysis, video case analysis and statistical analysis methods were adopted to study 120 teachers (40 novice teachers, 40 key teachers, and 40 experienced teachers) from eight participating schools during three phases in one academic year. The development and change...
In this paper, we present an interference problem due to the synchronization sequence collision between adjacent nodes in heterogeneous network environment. One of the possible solutions for the synchronization sequence collision is to newly define some kinds of synchronization sequences in system configuration. From this point of view, we propose an effective sequence generation method and suggest...
Our recent work, using both computer-animated and natural images, demonstrates that infants' eye movements are sequentially structured. In particular, we employ a simple recurrent network (SRN) to estimate the learnability of infants' gaze sequences. The current study directly compares this learnability metric with infants' global looking time on a trial-by-trial basis, during both an habituation...
This paper presents a new approach to user identity currently being explored within the SuperIdentity project and outlines the specific role that biometric measurements can contribute towards a modelling process. The SuperIdentity project aims to define a novel holistic model wherein the proven strengths of relationships between facets of identity are mapped. These facets are drawn from both real...
In this study, a chaotic analysis approach was applied to a time series composed of seismic moment of events occurred in mine of Dong Gaussian copper mine subordinate to Tong Ling Nonferrous Metals Group Co. In Anhui province, China. The chaotic attractor dimension and the largest lyapunov index were put forward to determine whether the seismic flow of rock is chaotic and the degree of chaos. The...
There have been numerous studies involving research and development, for detecting falls exhibited by the elderly. Considering that the prevention of a falling elderly is much more complex to address and estimate, very little research has been done. In fact research is often strictly limited resourceful medical organizations that have specialized clinical tools. Human locomotion, particularly “Walking”...
Economic globalization has intensified the transactions among companies' cross-regional affiliated parties. More and more enterprises manipulate profit to obtain the tax benefits through transfer pricing. At the same time. intangible assets are becoming the main driving factors for enterprises' value creation. It has become a trend that lots of companies are transferring profit or implementing other...
Early analysis does not support a link between students' motivation levels and their survey participation rates, suggesting that repeated sampling throughout a semester may be more capable of documenting a representative cross-section of student experiences than we originally expected.
Research methodology education is one of the less studied and discussed areas of computing education. Underplaying methodological education starts from computing curricula, which discuss methodology to different degrees, depending on the branch of computing. In computer science education research, programming courses have been analyzed through and through, but methodology courses in computing are...
In this paper we will present a case study and an analysis conducted to evaluate the use of lecture learning as a helpful companion to the classical teaching. This effort is done around the Opencast Matterhorn software, a system that is able to record classroom presentations and publish them on a LMS automatically, without the intervention of a technician dedicated to it. So we delivered a university-wide...
Numerous research studies have highlighted the importance of well-developed 3-D spatial skills for success in STEM related programs. Poor spatial skills, particularly among first-year students, can place them at a distinct disadvantage when completing introductory courses in mathematics, CAD, descriptive geometry, and graphic communications — first-year requirements in many STEM related programs....
Mathematics and physics courses are recognized as a crucial foundation for the study of engineering, and often are prerequisite courses for the basic engineering curriculum. But how does performance in these prerequisite courses affect student performance in engineering courses? This study evaluated the relationship between grades in prerequisite math and physics courses and grades in subsequent electrical...
The purpose of this research paper is to examine the relationship between self-concepts relating to two attributes necessary for successful engineers in today's society: creativity and global readiness. Some previous studies have shown a positive relationship exists between multicultural exposure and later creative performance. However, no studies were found that examine the relationship between students'...
In the modern enterprise system, business management and ownership are separate. Thus, the agency relationship comes out. Under the asymmetric and insufficient information, the manager would be contrary to the pursuit of business objectives and maximize their own interests, resulting in agency costs. Western countries have been respected that debt financing plays very good constraint on managers,...
We present a sport skill classification using time series motion picture data, focused on table tennis. We do not use body nor skeleton model, but use only hi-speed motion pictures, from which time series data are obtained and analyzed using data mining methods such as C4.5 and so on. We identify internal models for technical skills as evaluation skillfulness for forehand stroke of table tennis, and...
In this paper, we focus on the problem of estimating users' home locations in the Twitter network. In order to solve the aforementioned problem, we propose a Social Tie Factor Graph Model (STFGM) for estimating a Twitter user's city-level location based on the following network, user-centric data and tie strength. In STFG, relationships between users and locations in social network are modeled as...
D-S evidence theory has been widely used in various fields of information fusion due to its efficiency in dealing with uncertain information. Unfortunately, combination of conflicting evidences with the classical Dempster's rule may produce the counter-intuitive results. In this paper, Definitions of correlation coefficient and credibility are first presented, followed by the introduction of evidence...
Two novel recursion constructions of mutually orthogonal complementary pairs (MOCPs) are respectively presented on the basis of concatenation and interleaving operations. For the proposed set consisting of MOCPs, the zero-shift cross-correlation function between any two complementary pairs is equal to zero, that is, all of complementary pairs in MOCPs set are orthogonal to each other, as suggested...
In today consumer world, product search engines have been played key roles for consumer information seeking and decision making process. However, due to the volume, variety and velocity of information plus the nature of human beings, it becomes very hard to identify what information and how it is used by a consumer. Therefore, in this paper a Human Behavior Analyzer Framework is proposed to gain some...
