Human Interaction in meetings is one of the famous fields of social dynamics. Meeting is integral part of every organization. In this, meeting outcome is extracted using tree based approach. Meetings contents or conversation are available in forms such as audio, video and text. In this, pattern of meeting is extracted from text document. An interaction is represented in the form of tree. Meeting Output is generated using data mining technique. Firstly the contents are filtered, extracted and steamed. Secondly classification is done into six categories propose, comment, acknowledgement, request Info, ask Opinion, pos Opinion, and neg Opinion. Next the interaction tree is constructed which represent the interaction flow of meeting. Finally the meeting output is generated from interaction tree using frequent pattern mining algorithm. The behavior of person is determined which includes a person who proposed a lot of ideas, a person with positive or negative attitude.

RapidMiner is a software for machine learning, data mining, predictive analytics, and business analytics. The server will record large web log files when user visits the website. Extracting knowledge from such huge data demands for new methods. In this paper, we propose a web usage mining method with RapidMiner. At first, the redundant files in log file are deleted by Matlab and then we mines web log which has been pretreated with RapidMiner, it obtains the custom of different user to visit the website by processing and analyzing log file, and mines unusual rules, and provides the reference for the policy decision and construction of website. Experimental result analysis show that, applying RapidMiner in web usage mining, will obtain frequent model which user visits the website, manage to optimize the website structure and recommends for users.

Here we report a haptic virtual reality simulator for root canal treatment (endodontic procedures). A virtual jaw model was extracted from CT data of a live patient and the volumetric data obtained were visualized using a Marching Cubes algorithm. Collision detection and collision response algorithms were developed using a voxel-based approach. Removal of bone was visualized using a modified real-time Marching Cubes method and deformation of the K-files in the internal surface of tooth canal was simulated haptically and graphically using OpenGL and HDAPI of OpenHaptics Libraries. Using a haptic robot (Omni Phantom) the user can burr the enamel and dentin until reaching the pulp chamber and then the internal surface of a root canal can be cleaned using a simulated K-file.

The majority of methods for line clipping make a rather large number of comparisons and involve a lot of calculations compared to modern ones. Most of the times, they are not so efficient as well as not so simple and applicable to the majority of cases. Besides the most popular ones, namely, Cohen-Sutherland, Liang-Barsky, Cyrus-Beck and Nicholl-Lee-Nicholl, other line-clipping methods have been presented over the years, each one having its own advantages and disadvantages. In this paper a new computation method for 2D line clipping against a rectangular window is introduced. The proposed method has been compared with the afore-mentioned ones as well as with two others; namely, Skala and Kodituwakku-Wijeweera-Chamikara, with respect to the number of operations performed and the computation time. The performance of the proposed method has been found to be better than all of the above-mentioned methods and it is found to be very fast, simple and can be implemented easily in any programming language or integrated development environment.

Order placingis a crucial phase of lifecycle of a Mass-customizable product and seeks improvement in Mechanical industry. 'Product Configurator' is a good solution to bring in data transparency and speed up the process. Configuration tools arebeing used on a very small scale,reasons being lack of awareness and dearer costs of existing tools. In this research work a product configurator is developedfor Hydraulic Actuator (HA).This method uses Applicable Programing Interface (API) of a CAD tool coupled with Visual Basics (VB) and MS Excel.Itis a standaloneapplication of VB and its integration into web portal can be the future scope. The final aim was to reduce time delay at CRM phase,bring more transparency in the ordering system and to establish a method which, small and medium scale enterprises canafford. Trails on the tool developed generated Part-Assembly drawings, BOM and JT files in moments.

Automatic image annotation has emerged as an important research topic due to its potential application on both image understanding and web image search. This paper presents a model, which integrates visual topics and regional contexts to automatic image annotation. Regional contexts model the relationship between the regions, while visual topics provide the global distribution of topics over an image. Previous image annotation methods neglected the relationship between the regions in an image, while these regions are exactly explanation of the image semantics, therefore considering the relationship between them are helpful to annotate the images. Regional contexts and visual topics are learned by PLSA (Probability Latent Semantic Analysis) from the training data. The proposed model incorporates these two types of information by MCDM (Multi Criteria Decision Making) approach based on WSM (Weighted Sum Method). Experiments conducted on the 5k Corel dataset demonstrate the effectiveness of the proposed model.

This article proposes an artistic approach to increase and enrich the understanding of Julia Sets. This approach includes the mathematical, the playful, the artistic and the computational dimensions. It is argued that these four dimensions are not disjointed or dissociated despite general rejection by traditional academic communities and art critics communities. Also, some significant collections of Computational Art or Computer-Generated Mathematical Art are mentioned. Four artistic creations based on Julia Sets are presented as examples using the CFDG language. Finally, an informal application of the approach was carried out and artistic production of students are presented and discussed.

The paper presents a technique for construction of C n interpolating rational Bézier spline curves by means of blending rational quadric Bézier curves. A class of polynomials which satisfy special boundary conditions is used for blending. Properties of the polynomials are considered. The constructed spline curves have local shape control that make them useful in such geometric applications as real-time trajectory generation and fast curve sketching.
