3276 results about "Visulation" patented technology

Visulation is a portmanteau describing a coupled system where graphic visualization and computer simulation occur simultaneously. Visulation is conducted in many GPGPU applications and commonly employs interactive visualization techniques.

Methods for interactive visualization of spreading activation using time tubes and disk trees

Methods for displaying results of a spreading activation algorithm and for defining an activation input vector for the spreading activation algorithm are disclosed. A planar disk tree is used to represent the generalized graph structure being modeled in a spreading activation algorithm. Activation bars on some or all nodes of the planar disk tree in the dimension perpendicular to the disk tree encode the final activation level resulting at the end of N iterations of the spreading activation algorithm. The number of nodes for which activation bars are displayed may be a predetermined number, a predetermine fraction of all nodes, or a determined by a predetermined activation level threshold. The final activation levels resulting from activation spread through more than one flow network corresponding to the same generalized graph are displayed as color encoded segments on the activation bars. Content, usage, topology, or recommendation flow networks may be used for spreading activation. The difference between spreading activation through different flow networks corresponding to the same generalized graph may be displayed by subtracting the resulting activation patterns from each network and displaying the difference. The spreading activation input vector is determined by continually measuring the dwell time that the user's cursor spends on a displayed node. Activation vectors at various intermediate steps of the N-step spreading activation algorithm are color encoded onto nodes of disk trees within time tubes. The activation input vector and the activation vectors resulting from all N steps are displayed in a time tube having N+1 planar disk trees. Alternatively, a periodic subset of all N activation vectors are displayed, or a subset showing planar disk trees representing large changes in activation levels or phase shifts are displayed while planar disk trees representing smaller changes in activation levels are not displayed.

System and method for rapid design, prototyping, and implementation of distributed scalable architecture for task control and automation

The present invention provides a system and method for simplifying and accelerating the process of prototyping, real-world simulation, and implementation of virtually any task performance system or device, thereby dramatically reducing the design-to-implementation cycle time and expense. The inventive system includes a development system that provides a user, with visual tools to interactively and dynamically partition a previously designed visual system model of the task performance system or device, and then interactively or automatically assign the partitions to corresponding selectable target components, to produce a prototyped system ready for conversion to executable form suitable for implementation. The inventive system and method can also be readily used to automatically generate any instruction sets that are necessary for implementing the prototyped task performance system in actual target components of one or more emulation and/or production target systems. A novel automatic executable program code generation process that can be advantageously utilized is also provided in accordance with the present invention. Finally, the present invention may optionally include a data handling device that enables real-time monitoring and management of a remote target system from one or more user systems, as well as a set of tools for designing interactive visual instrument panels for that purpose.

Distributed knowledge data mining device and mining method used for complex network

The invention discloses a distributed knowledge data mining device and method used for a complex network. The distributed knowledge data mining device adopts a distributed computing platform which is composed of a control unit, a computing unit and a man-machine interaction unit, wherein the innovation key is to finish the calculated amount needed by a multifarious clustering algorithm in the data mining by different servers so as to improve the efficiency of the data mining. Aiming at different knowledge data, the degrees of relation and the weights of knowledge data also can be computed by applying different standards, so that a more credible result is obtained. A second-level clustering mode is adopted in the knowledge data mining process; the result of the first-level clustering is relatively rough, but the computing complexity is very low; and the computing complexity of the second-level clustering is relatively high, but the result is more precise. By combining the first-level clustering with the second-level clustering efficiently, the distributed knowledge data mining device improves the time complexity and clustering precision greatly in comparison with the traditional first-level clustering mode. According to the invention, as a visual and direct exhibition network structure and a dynamic evolutionary process are adopted, references are provided for the prediction in the fields of disciplinary development and hotspot research.
