Data visualization is a science and technology research on data visual form, which is originated in the 50's of the twentieth Century. It went from scientific visualization, information visualization to data visualization. Based on computergraphics and pictures data visualization display and reveal the main information contained in data. Data visualization contains data acquisition, data analysis, data processing and data modeling. Based on psychology the motivation of data visualization is to expand the scope of visual perception which is easier to get information than other biological perceptions while the effect is *** science and technology greatly extends the human sensory "arms".Visual perception has very long "arm" and often "robs" other perceptions' "busi-ness". This paper introduces the basic concept and main content of data visuali-zation, reveals the essence of data visualization. Through the "Agricultural plan-ning visualization" case, the technology process of data visualization applied in production has been established, which can be described as 4 steps operated by order. The first step is to determine and decompose a target. The second step is data acquisition and processing. The third step is models designing and expres-sion. The last step is video production.

Clarifies modern data analysis through nonparametric density estimation for a complete working knowledge of the theory and methods Featuring a thoroughly revised presentation, Multivariate Density Estimation: theory, practice, and Visualization, Second Edition maintains an intuitive approach to the underlying methodology and supporting theory of density estimation. Including new material and updated research in each chapter, the Second Edition presents additional clarification of theoretical opportunities, new algorithms, and up-to-date coverage of the unique challenges presented in the field of data analysis. The new edition focuses on the various density estimation techniques and methods that can be used in the field of big data. Defining optimal nonparametric estimators, the Second Edition demonstrates the density estimation tools to use when dealing with various multivariate structures in univariate, bivariate, trivariate, and quadrivariate data analysis. Continuing to illustrate the major concepts in the context of the classical histogram, Multivariate Density Estimation: theory, practice, and Visualization, Second Edition also features: Over 150 updated figures to clarify theoretical results and to show analyses of real data sets An updated presentation of graphic visualization using computer software such as R A clear discussion of selections of important research during the past decade, including mixture estimation, robust parametric modeling algorithms, and clustering More than 130 problems to help readers reinforce the main concepts and ideas presented Boxed theorems and results allowing easy identification of crucial ideas Figures in color in the digital versions of the book A website with related data sets Multivariate Density Estimation: theory, practice, and Visualization, Second Edition is an ideal reference for theoretical and applied statisticians, practicing engineers, as well as readers interested in the theoretical aspects of nonparametric esti

Planning in education is a process that can determine the success of learning. This has major impact in engineering education, where students have to develop complex competences in order to make decisions that can influence the world and humankind. Teachers are reluctant regarding the effective practice of planning educational processes, identifying the lack of time and appropriate pedagogical training as main causes for the problem. Our aim is contribute to solve this problem. This paper presents the exploration of the capabilities of conceptualization of planning by the IMS-LD educational modelling language, through CADMOS authoring tool. To do so we used a learning object of a discipline of a computer Engineering higher education course. Several specifications were made in CADMOS, based on different learning strategies common used in engineering education. The results show that IMS-LD and CADMOS can help and simplify the planning process for teachers, allowing them to implement changes, reuse and share planning products. Limitations were identified, but they do not preclude the use of the tool for planning.

Demonstrating the approach to protract the figure of three-dimensional graphs with geometrical forms in two-dimensional planes, graphics is a basic technical discipline of examining protracting engineering drawings using the method of projection and addressing issues on space geometry as well as its theory and approach. graphics is also a kind of semiotic system of writing. China boasts of rich tradition of graphics with amazing architectural drawings in Pre-Qin period, booming theories of graphics in Wei and Jin Dynasties, refined protracted drawings in Song and Yuan Dynasties, and graphics being regarded as important instruments in Ming and Qing Dynasties when thorough apprehension were pursued in order to seek the practice of administration. It not only forms the basis for modem and contemporary graphics in China, but also shapes the future development of graphics.

Introduction: The present study evaluated the feasibility of using an iPad application or "app" for algebra-readiness mathematics, with accompanying braille materials and accessible graphics, when used in authentic educational settings. Methods: Twenty-nine students with visual impairments in grades 4-11 used the materials under the direction of their teachers of students with visual impairments (N = 19). Twenty percent of the mathematics problems included graphics such as maps, line graphs, and bar graphs. Students and teachers of students with visual impairments provided feedback about the feasibility of using the app with supplemental materials, and made suggestions for additional features to improve the instructional package. Results: Students completed 984 word problems and solved 80% of them correctly within three attempts. The use of some features such as hints and "worked-example" videos was low. Participants provided suggestions for improvement of the app features and accessible graphics. Discussion: Students and teachers of students with visual impairments were able to use the materials successfully, and comments were generally positive. Participants' comments and suggestions were used to revise the app and materials. Implications for practitioners: The study results contribute to the growing body of knowledge about the potential value of tablet-type devices for use by visually impaired students.
