Engineering: Faculty Publications

Waterborne viruses are responsible for numerous diseases and are abundant in aquatic systems. Understanding the fate of viruses in natural systems has important implications for human health. This research quantifies the uptake of the bacteriophage T4 and the enteric virus echovirus 11 when exposed to the filter feeders Tetrahymena pyriformis and Daphnia magna, and also examines the potential of viral transfer due to trophic interactions. Experiments co-incubating each species with the viruses over 72-96 h showed up to a 4 log virus removal for T. pyriformis, while direct viral uptake by D. magna was not observed. However, viral uptake by …

Co-Milling And Cofiring Of Woody Biomass With Coal In Utility Boilers: Enabling Technology Through Experiments And Modelling, Seyedhassan Fakourian

Theses and Dissertations

Beetle-killed trees and woody residues degenerate and may lead to wildfires and uncontrolled CO2 emission. Woody biomass is known as a neutral CO2 solid fuel since it generates the same amount of CO2 that takes from atmosphere during its growing up. Cofiring woody biomass with coal in existing coal power plants is a reasonable solution to reduce the net amount of CO2 emission and decrease the risk of wildfires. However, there are some challenges ranging from providing and handling the woody biomass to the operation of cofiring woody biomass with coal. Co-milling of the fuels and ash deposition on the …

A U-Shaped Complementary Open Loop Defective Ground Structure With Slow Wave Structure For Mode Conversion And Common Mode Noise Suppression, Liang Zhang, Qiang Ming Cai, Xiao Bo Yu, Lin Zhu, Chao Zhang, Yinglei Ren, Jun Fan

Electrical and Computer Engineering Faculty Research & Creative Works

With the increase of signal rate, differential interconnection becomes more and more widely used. However, when the differential pair is asymmetric in layout, e.g., bending lines, common mode noise will be produced in the circuit, which may further cause EMI problems. In this paper, an efficient method, i.e., combing a U-shaped complementary open loop defective ground structure (DGS) with adding slow wave structure at the inner bending line, is proposed to suppress the differential-to-common mode conversion and common-mode noise of right-angle bend discontinuity for differential signaling. The simulation results show that the mode conversion can be reduced to less than-50dB …

Fext Reduction Using Mushroom Structures Thickened Soldermask For Ddr5 Pcbs, Xiao Bo Yu, Qiang Ming Cai, Liang Zhang, Chao Zhang, Lin Zhu, Yinglei Ren, Jun Fan

Electrical and Computer Engineering Faculty Research & Creative Works

Far-end crosstalk (FEXT) between adjacent signal lines is one of the most critical factors affecting signal integrity (SI) in double data rate 5 (DDR5) printed circuit boards (PCBs). In this paper, a new method for FEXT reduction, based on mushroom structures thickened solder mask (MSTS) for coupled signal lines, is proposed and investigated. From the simulated S-parameters results, FEXT of this proposed method can be suppressed among a very wide frequency range. Additionally, the FEXT is decreased more than 25dB around the main frequency of DDR5, compared with the traditional signal routing. Finally, both frequency and time domains results show …

Bridge Resilience Assessment With Inspire Data, Iris Tien

INSPIRE-UTC Annual Meetings

Robotic data collection, both automated and remote, will enable post-disaster assessment of bridge components where it would normally be difficult and potentially dangerous for manual inspection by field workers to do so.

This project aims to develop and validate a new framework that uses the data collected from the robotic exploration of infrastructure, particularly after a disaster, to assess the condition of bridges and prioritize these structures for repair. This will improve the resilience of the transportation system to disasters by targeting bridge repairs and enabling resources to be distributed more effectively across the system for more rapid recovery after …

Climbing Robots With Automated Deployment Of Sensors And Nde Devices For Steel Bridge Inspection, Hung La

INSPIRE-UTC Annual Meetings

The PI was a research scientist/faculty at Rutgers University who successfully developed in 2014 a Robotic Assisted Bridge Inspection Tool (RABIT) for bridge deck inspections. Other bridge elements, such as girders and columns, or even underside of bridge decks are difficult to access and remain a challenge for efficient inspection. Like visual inspection, current practices for bridge maintenance are equally time consuming and expensive. Automation of simple maintenance actions such as bearing cleaning and concrete sealing with robots will lead to a leap forward to the next-generation strategy of bridge maintenance.

This project aims to develop and prototype automated climbing …

Bridge Inspection Robot Deployment Systems (Birds), Bo Shang

INSPIRE-UTC Annual Meetings

Climbing robots for both concrete and steel bridges and UAVs are being developed to support bridge inspection with advanced evaluation technologies at the INSPIRE University Transportation Center. They are mostly applicable to large open areas with little or no obstacles. For I-shaped beams or girders, climbing along the cross section of these structural members is not a trial task. In particular, a climbing robot may not have a sufficient footprint to make a safe turn from the inner to outer face of a top or bottom flange. In this case, an unmanned vehicle is conceived to facilitate I-girder inspection and …

Mobile-Manipulating Uavs For Sensor Installation, Bridge Inspection And Maintenance, Paul Oh

INSPIRE-UTC Annual Meetings

Mobile manipulating UAVs have great potential for bridge inspection and maintenance. Since 2002, the PI has developed UAVs that could fly through in-and-around buildings and tunnels. Collision avoidance in such cluttered near-Earth environments has been a key challenge. The advent of light-weight, computationally powerful cameras led to breakthroughs in SLAM even though SLAM-based autonomous aerial navigation around bridges remains an unsolved problem.

In 2007, the PI integrated a mobile manipulation function into UAVs, greatly extending the capabilities of UAVs from passive survey of environments with cameras to active interaction with environments using limbs. Mobile-manipulating UAVs have since been demonstrated to …

Autonomous Wall-Climbing Robots For Inspection And Maintenance Of Concrete Bridges, Jizhong Xiao

INSPIRE-UTC Annual Meetings

Since 2002, the PI’s group has developed four generations of wall-climbing robots for NDE inspection of civil infrastructure. These robots combine the advantages of aerodynamic attraction and suction to achieve a desirable balance of strong adhesion and high mobility. They don’t require perfect sealing and can thus move on smooth and rough surfaces, such as brick, concrete, stucco, wood, glass, and metal. For example, Rise-Rover uses two drive modules to carry their middle compartment with payload up to 450 N. Ground penetrating radar (GPR)-Rover and Mini GPR-Rover are custom designed to carry a GSSI’s GPR antenna for subsurface defect detection …

The INSPIRE University Transportation Center will develop a remotely-controlled robotic platform that helps with these labor-intensive tasks and allows engineers to focus on decision-making processes. An important mission of INSPIRE is to leverage users’ capability of implementing, and interacting with, the robotic platform. Therefore, a long-term plan has been made to create a framework of …

Developing A Robotic Simulator And Video Games For Professional And Public Training, Sushil Louis

INSPIRE-UTC Annual Meetings

Civil engineers are not educated with robotics. They need to be trained on the job with effective tools. The most recent simulation trainer that the PI has built is currently being used by the United States Navy to train surface warfare officers in decision making under stress. In a crowded in-port environment, the crew on a ship’s bridge is trained to probe and identify suspicious boat behavior within the port’s traffic pattern. Officers in charge of the simulation training lesson use software for high-level control of dozens of other ships, boats, and aircrafts that quickly react and adapt to the …
