Abstract: In a recent survey, its observed that there is arise in crime rate in India, and due to this, many peoplefeel unsafe in this country. So to reduce it, predicting thecrime before it happens is very important. IndianGovernment uses a software called CCIS (Crime CriminalInformation System), this software is only used to storeinformation, but with the stored information, it doesn’t doanything else, the existing systems predict crime only on aday basis, but it doesn’t predict exactly at what hour is itgoing to occur, to predict it on a hour basis, accuracy isimportant, so to analyze and predict crime, the accuraciesof machine learning algorithms such as KNN, Decision treeand Random forest are compared in order to use the bestfor analysis and prediction.

Abstract: Covid-19 is a dangerous infection which is caused by SAR-COV 2 (stands for severe acute respiratory syndrome coronavirus 2). The first known coronavirus case was found in Wuhan, China in 2019. On 11th March 2020 the World health organization declared covid-19 as an epidemic and from that point of time it has been mutated into various variants and thus causing a lot of health issues among the people. It has affected the people as well as the economy of the country in a negative way. Major symptoms which were recognize from the people who were affected from the covid includes cough, fatigue, constant fever, difficulty during breathing and loss of smell and taste. In this study, an overview of analysis of the variants of the coronavirus as well as impact of covid-19 in various countries has been studied in a detailed manner. In order to show the impact of Covid-19 on a clear picture, the study has been visualized with the help of various charts and figures in order to make it easy to understand. Techniques which provide effective visualization is discussed. A comparison of the prediction models with deep learning algorithms is also mentioned in this paper. This study would be helpful for covid-19 research as it gives a clear view of trends and different aspects of covid-19 as well as a detailed view on the variants which were formed.

Abstract: The development of general aviation is very rapid, but general aviation has not built the platform of flight data visualization all the time. A system of constructing the flight data visualization system based on FlightGear Simulation tool has been introduced in this paper. It contained using VC++ exploitation platform and MFC frame. Firstly the file of flight data was processed by XML configuration document. And then the Data were read by opening documents in FlightGear simulation to recreation and the same time the instrument would receive the data from FlightGear simulation with network in order to synchronously display flight data. The experiment proves that the system has good simulation effectiveness and real-time performance.

Abstract: Data visualization is an emerging technology in location-based service. In this paper, the principle of moving target tracking and the transformation of coordinates were introduced. Latitude-longitude pairs of moving object were obtained by globe satellite data receiver and the map matching were adopted to realize the real-time target tracking correspondingly. Finally, the measurement data in location-based services were analyzed and presented by data visualization technology. The experiment results show the validity of the method.

Abstract: The article in infographics for example, analysis and data visualization aesthetic relationship, data visualization is an excellent creative product design aesthetics and rigorous engineering science. Presented with a very beautiful form can be very boring tedious data. I try to find the background behind each data graph, add labels and notes, hoping to deeper understanding of the meaning of these charts are presented, rather than stay on for the "nice" praise. These pictures can not speak, but they are more powerful than words and language. Finally, the paper analyzes the value and prospects of data visualization have. Analysis on Design Aesthetics What is the Beauty of Design As a reality-based artistic creative activity, design shows unique aesthetic characteristics. For the beauty of design, its creation proves to grow out of products shape and design, and its realization is attributed to consumers. To create a wonderful experience for users, designer cognizes aesthetic object from user perspective and interprets the emotional meaning of the works according to the possible rules of psychological cognition. Only in this way, will users be able to perceive the beauty of design. That is, what designer reflects is not the subjective feeling but the commercial purpose and audiences aesthetic trend. For a design, the aesthetic value is primarily embodied in application, with aesthetic creation intended to serve the society, the market and people. The inability to attain the said objective will signify the failure ofa design.

Abstract: Most machine health monitoring techniques are likely to suffer from ineffective selection of state features, and the increasing redundancy of raw signals. As a new strategy, an interactive and artistic monitoring approach is presented. Its basic concept is to transform raw signals into artistic graphs rather than obscure waveforms. The entire procedure includes three steps: signal acquisition, plotting artistic graphs and interactive diagnosis. In the case of numerical control machine tools, an interactive and artistic monitoring prototype system is developed based on the integration of the open-source Arduino platform and the open-source Processing language. Experimental results indicate that the artistic visualization of measured data facilitates the identifications of machine condition and the diagnosis of observed symptoms.

Abstract: In the search for a new method of feature tracking of vector field, Theisel and Seidel proposed the concept of feature flow field [, In their paper, a flat time-varying flow field and multi-vortex structure, vortex will automatically extract and track based on the concept of feature flow field. The method used for tracking the vortex core flow line integral, by extracting the vortex areas of flow field to determine the vortex core range, precision tracking vortex core in the three-dimensional feature flow field and recording the specific path of evolution in the integrand flow line. The new algorithm using the flow line can describe the dynamic behavior of characteristics of vector field. The evolution of the flow field is more intuitive to observe the evolution of different periods, which laid the basis for visualization.

Abstract: George Leslie Mackay (1844-1901), the first Presbyterian missionary to northern Taiwan, is considered to be one of the most important persons who influence the development of education and medicine in Taiwan. Recently, the manuscripts written by Mackay which detailed his work from 1871 to 1901 in Taiwan have been computerized and published as Mackays diaries. Researchers who are interested in historical topics concerning religious, educational and medical development in Taiwan hence concentrate their attention on these materials. However, little research applied computational techniques to analyze the content of the diaries. That motivated us to apply text mining techniques to explore the content of diaries. The content analysis methodology was used in this research to unveil the context of Mackays missionary work in northern Taiwan. Finally, the context was presented by data visualization techniques.

Abstract: In this paper, we present one method of acquiring the evaluation data of health habits using FitBit sensor. After registering in Fitbit.com, we create a customer client based on OAuth protocol and obtain the authorization of operational resources. Then we access to health habits assessment data, and complete data visualization. Finally, we provide the experiments results. The experiments results prove our method is feasible and valid. Our method has been used in our practical application.
