Parallel coordinate is a popular tool for visualizing high-dimensional data and analyzing multivariate data. With the rapid growth of data size and complexity, data clutter in parallel coordinates is a major issue for Big Data visualization. This has given rise to three problems, 1) how to rearrange the parallel axes without the loss of data patterns, 2) how to shrink data attributes on each axis...
Information visualization is a very important tool in BigData analytics. BigData, structured and unstructured data which contains images, videos, texts, audio and other forms of data, collected from multiple datasets, is too big, too complex and moves too fast to analyse using traditional methods. This has given rise to two issues; 1) how to reduce multidimensional data without the loss of any data...
Clustered graph drawing is widely considered as a good method to overcome the scalability problem when visualizing large (or huge) graphs. Force-directed algorithm is a popular approach for laying graphs yet small to medium size datasets due to its slow convergence time. This paper proposes a new method which combines clustering and a force-directed algorithm, to reduce the computational complexity...
Big Data, which contains image, video, text, audio and other forms of data, collected from multiple datasets, is difficult to process using traditional database management tools or applications. In this paper, we establish the 5Ws model by using 5Ws data dimension for Big Data analysis and visualization. 5Ws data dimension stands for, What the data content is, Why the data occurred, Where the data...
Clustered graphs have been widely consisted in Graph Drawing to overcome the problem of drawing large (or huge) graphs with thousands, or perhaps millions of nodes. Force-directed algorithm is one of the available approaches to draw such graphs with good layouts. However, the force directed methods are often produce very different layout outcomes based on different clustering algorithms that greatly...
According to the disadvantages of the recent current transformer in reliability stability and accuracy, which is caused by analog transmission and the shortage of the complex cabling with many nodes in the signal of current transformer, a three-phase power current transformer based on CAN transmission is designed. The design ideas and basic composition of the current transformer is intrduced in this...
The internet is becoming more popular, and e-learning is in the same situation too, in this paper, the Mastery and Flow theory will be discussed. In the e-learning many people are involved in the digital content study?learning and etc., in the past few years, if learner want to catch a new knowledge or technology, he/she will spend a lot of time and fortune, but after internet and web skill become...
The learning organization (LO) concept continues to be regarded as a key factor for success in organization theory texts, however managers need an effective instrument to assess learning organization competence and weaknesses. This paper reports a field test of the ASTD LO profile questionnaire, followed by survey of respondents to assess the utility of this LO profile questionnaire. Respondents feedback,...
With the development of information technology, information goods will become an important component of people's daily consumption, response to the characteristics of information goods, how to provide safe and efficient way to implement micropayment system become more and more important. Ajax is a novel technology using in rich-client web application recently, it provide a better way of information...
The timetabling problem is a NP-complete problem which has been committed to finding a solution by the field of operations research and computer but has not got a good solution. The timetabling is the most important problem in the course scheduling. With the development of disciplines, the change of the size and direction of enrollment, increasing the difficulty of the Course Scheduling. This paper...
We observe the movement of Camponotus japionicus Mary with the use of high speed digital photography and computer assistant analysis. The experiment not only provides biomimetic foundation to multi-legged robotspsila polynomial trajectory planning which is deduced by mathematics, but also gives five conclusions which apply to hexapod bio-robots marching locomotion planning. The first is the fundamental...
