Publication number: 20240118150Abstract: The present disclosure provides a method for testing an internal force increment of an arch bridge suspender by inertial measurement, including the following steps: (1) selecting a suspender to be tested with internal force increment, and mounting an acceleration sensing device or a speed sensing device at a lower edge of the suspender to be tested; (2) setting an appropriate sampling frequency and collecting signals; (3) processing information data collected in step (2) by using Formulas; and (4) recording a result of the information data processing and obtaining the internal force increment of the suspender. The method can obtain the internal force increment of the suspender by collecting acceleration or speed signals of the lower edge of the suspender and performing calculation from the signals. This method has the advantages of simple and convenient testing, high replicability and low test cost.Type: ApplicationFiled: October 8, 2021Publication date: April 11, 2024Inventors: Hua Wang, Longlin Wang, Tianzhi Hao, Zehua Xie, Mengsheng Yu, Xiaoli Zhuo, Yuhou Yang, Jiejun Ning, Xirui Wang, Xi Peng, Kainan Huang, Junhong Wu

Publication number: 20210042822Abstract: Techniques are provided for testing policy modules for bias. Policy modules are software modules that generate lending decisions based on information about loan applicants. The techniques involve performing multiple testing iterations based on each test case. For example, in one iteration, values for all input parameters of the policy module may come from the test case. That iteration produces a “baseline” lending decision. During other iterations, the values for most input parameters do not change. However, for the one or more input parameters that correspond to the characteristic for which bias is being tested, the input values are changed from iteration to iteration. For example, when checking for age bias, the age of a loan applicant may be varied with each iteration. The lending decisions generated based on each test case are collectively referred to as a “sibling batch” of lending decisions.Type: ApplicationFiled: August 5, 2019Publication date: February 11, 2021Inventors: Jianju Liu, Jianglan Han, Xirui Wang

Patent number: 9291758Abstract: Nanorods assemblies that have lengths in excess of 50 microns to meters are formed from contacting rice-shaped colloidal superparticles that are aligned along the long axis of the colloidal superparticles. The rice-shaped colloidal superparticles are formed from a multiplicity of nanorods with a high degree of association that is end to end to form colloidal superparticles that are in excess of three microns in length and have a length to diameter ratio of about three or more. Methods of preparing the rice-shaped colloidal superparticles employ mixing with an additional ligand to the nanorods to bias the self assembly of the nanorods by solvophobic interactions. Methods of preparing the nanorods assemblies include the infusion of the rice-shaped colloidal superparticles into microchannels patterned on a substrate, wherein the rice-shaped colloidal superparticles' long axes align in the microchannels.Type: GrantFiled: December 16, 2013Date of Patent: March 22, 2016Assignee: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.Inventors: Yunwei Charles Cao, Tie Wang, Xirui Wang
