Event Name Date Description
Seminar: Non-Contact Air-Coupled Sensing for NDT of Concrete Infrastructure 04/17/2014 - 1:00pm - 2:00pm

The Department of Mechanical & Energy Engineering

Presents

Non-Contact Air-Coupled Sensing for NDT of Concrete Infrastructure

Thursday April 17th, 2014
D212 UNT Discovery Park

1:00-2:00 pm

Speaker: Dr. Jinying Zhu,

Department of Civil, Architectural and Environmental Engineering at The University of Texas at Austin

 

Delaminations detected by air-coupled impact-echo test

About the Seminar:

With aging of our nation’s infrastructure, development of rapid and reliable sensing techniques becomes more important than ever to reduce assessment related cost and to improve safety and resilience of critical structures.  Air-coupled ultrasonic non-destructive testing (NDT) provides a solution for rapid scanning of large concrete structures.  In this presentation, I will review the development of air-coupled sensing technology for civil engineering applications and present most recent progress in realizing a fully non-contact air-coupled sensing system. The presentation will show four stages of the research: 1) feasibility study of air-coupled sensing through theoretical analysis; 2) experimental validation of air-coupled surface wave and impact-echo tests; 3) improvement of signal-to-noise ratio by using a parabolic reflector; and 4) most recent progress in development of a non-contact, spark acoustic source focused by an ellipsoidal reflector. A demonstration of air-coupled testing using a robot climber will be presented.

About the Speaker:

Jinying Zhu is an assistant professor in Department of Civil, Architecture and Environmental Engineering at the University of Texas at Austin. She received her Ph.D. degree in Civil Engineering from the University of Illinois at Urbana-Champaign in 2006. Her research expertise and interests include NDT for concrete, wave propagation, cement material characterization using innovative sensing techniques. Dr. Zhu is the pioneering researcher in air-coupled sensing for concrete. Dr. Zhu is a recipient of the ASNT Fellowship Award in 2012, and three time winner of ACI-James Instrument Award.

 

Seminar: Stochastic Simulation, Modeling & Optimization of Complex Systems via Parameterized Model Reduction 04/18/2014 - 10:30am

Department of Electrical Engineering Proudly Presents a Seminar on

Stochastic Simulation, Modeling & Optimization of Complex Systems via Parameterized Model Reduction

By Dr. Luca Daniel

Massachusetts Institute of Technology

April 18, 2014

Time: 10:30 am

Location: EENG B242

Design Day 2014 04/25/2014 - 9:30am - 5:00pm

All seniors in Electrical Engineering, Mechanical and Energy Engineering, Materials Science and Engineering, Computer Engineering and Engineering Technology culminate their undergraduate engineering education with a two-semester capstone, senior design project. The senior design course provides students with hands-on experience at solving ‘real world’ problems while working in a team environment. Students learn important concepts such as project planning, designing, scheduling and working as a cohesive group to accomplish an objective. Many of the senior design projects in our college are sponsored by industry.
