Publication number: 20190161831Abstract: A softening resistant copper alloy, a preparation method, and an application thereof, the softening-resistant copper alloy, comprising 0.1%-1.0 wt % Cr, 0.01%-0.2 wt % Zr, 0.01%-0.10 wt % Si, and ?0.10 wt % Fe, and with the remaining of copper and inevitable impurities, wherein the microstructure of the copper alloy contains comprises: an elemental Cr phase, a Cu5Zr phase, and a Cr3Si phase. In the copper alloy of the present invention, the high-temperature softening resistance effect of the material is improved by adding a proper amount of Si to form a compound Cr3Si, and the strength and the high-temperature softening resistance of the material are further improved by strengthening the copper alloy matrix by the elemental Cr phase and the Cu5Zr phase, using the synergistic effect of the Cr3Si phase and the elemental Cr phase and by controlling the content of the impurity Fe. The copper alloy can be applied to contact lines and welding materials to prolong the service life of the materials.Type: ApplicationFiled: August 18, 2017Publication date: May 30, 2019Inventors: Yongjun Pei, Jijun Wang, Er Zhang, Yubo Song, Juan Li, Weiwei Li, Renchang Hu, Mengtao Tian

Publication number: 20120185424Abstract: The present invention relates to a method for generating hypotheses automatically from graphical models built directly from data. The method of the present invention links three key scientific concepts to enable hypothesis generation from data driven hypothesis-models: including the use of information theory based measures to identify informative feature subsets within the data; the automatic generation of graphical models from the informative data subsets identified from step one; and the application of optimization methods to graphical models to enable hypothesis generation. The integration of these three concepts can enable scalable approaches to hypothesis generation from large, complex data environments. The use of graphical models as the model representation can allow prior knowledge to be effectively integrated into the modeling environment.Type: ApplicationFiled: August 24, 2010Publication date: July 19, 2012Applicant: QUANTUM LEAP RESEARCH, INC.Inventors: Akhileswar Ganesh Vaidyanathan, Eric N.

Publication number: 20120004893Abstract: The present invention relates to a method for the automatic identification of at least one informative data filter from a data set that can be used to identify at least one relevant data subset against a target feature for subsequent hypothesis generation, model building and model testing. The present invention describes methods, and an initial implementation, for efficiently linking relevant data both within and across multiple domains and identifying informative statistical relationships across this data that can be integrated into agent-based models. The relationships, encoded by the agents, can then drive emergent behavior across the global system that is described in the integrated data environment.Type: ApplicationFiled: September 10, 2009Publication date: January 5, 2012Applicant: QUANTUM LEAP RESEARCH, INC.Inventors: Akhileswar Ganesh VAIDYANATHAN, Stephen D.
