Flood prediction model developed — ScienceDaily

The duration of floods can be determined by river flow, precipitation and atmospheric blocking. Now an international team of researchers led by Nasser Najibi and Naresh Devineni at The City College of New York is offering a novel physically based Bayesian network model for inference and prediction of flood duration. The model also accurately examines the timescales of flooding. Conceptualized by Najibi and tested on the Missouri River Basin, the statistical model is based on data in the area from…

Do sensors make infrastructure safer?

Matteo Pozzi in front of Scott Hall at Carnegie Mellon University. Credit: College of Engineering, Carnegie Mellon University Simply driving down the road gives you a sense for the current state of our infrastructure: crumbling and in need of repair. Aside from retrofitting or replacing current infrastructure with new construction and materials, new technology like sensors offers a way for inspectors to peer inside the systems almost continuously. But just placing a sensor on the side of a bridge doesn’t…

Scaling up innovative sensor installation on the Mighty Mac

MSU has developed sensors that can detect road wear, bridge defects and more. Some sensors have already been deployed to Michigan’s iconic Mackinac Bridge. Credit: MSU The first 20 prototype infrastructure sensors installed in 2016 on the Mackinac Bridge, powered solely by vibrations from traffic, have proven their durability and performed as intended. Now researchers from Michigan State University and Washington University in St. Louis are ready to roll out the next phase of testing, installing up to 2,000 of…

Duo presents at Emerging Researchers National Conference

The Emerging Researchers National Conference (ERN) in STEM selects top student researchers to present groundbreaking projects, with the goal of advancing their abilities to effectively communicate in the science community and ultimately their future careers. Two Mizzou Engineers were among the high-caliber students selected. Civil and Environmental Engineering’s Amber Peterein and Laura Wiseman each earned…

Research will help urban planners prioritize bike lanes

Credit: CC0 Public Domain A new virtual tool could help planners choose the best places to install bikes lanes in cities. The data-based tool builds on previous research at the University of Waterloo that validated the safety benefits of bike lanes for cyclists and motorists. Collected using sensors and a handlebar camera as researchers cycled hundreds of kilometres in Kitchener-Waterloo, Ontario, the data showed bike lanes virtually eliminate vehicles getting too close to cyclists when they pass them. …

Cutting-edge underwater mining system can give flooded mines a new lease of life

Credit: Andriy Solovyov, Shutterstock Europe has an estimated EUR 100 billion worth of unexploited mineral resources lying at depths of 500-1,000 m. Following centuries of active mining, the continent’s more accessible mineral deposits are mostly depleted. However, there are still deep-lying resources in abandoned flooded mines and in unmined underwater deposits that can’t be exploited using conventional dry mining techniques. Thanks to a novel underwater mining system developed by the EU-funded project VAMOS, currently unreachable mineral deposits will be extracted…

Four Mizzou Engineering faculty receive named professorships

Henry He, Guoliang Huang, Jian Lin and Erik Loehr (L-R, top to bottom) received named professorships this week. Last spring, faculty representatives from the College of Engineering developed a Faculty Honors Program to adhere to the campus guidelines for awarding faculty fellowships and honors. This program was approved by the Provost’s Office in March 2018. To select this year’s honorees, Dean Elizabeth Loboa sought recommendations from the College’s Dean’s Council for Teaching Excellence and Dean’s Council for Research Excellence. Henry…

Accurately predicting fracture mechanics can help industry optimize pumping, fracturing-fluid viscosity, other parameters — ScienceDaily

A new computational model could potentially boost efficiencies and profits in natural gas production by better predicting previously hidden fracture mechanics. It also accurately accounts for the known amounts of gas released during the process. “Our model is far more realistic than current models and software used in the industry,” said Zden?k Bažant, McCormick Institute Professor and Walter P. Murphy Professor of Civil and Environmental Engineering, Mechanical Engineering, and Materials Science and Engineering at Northwestern’s McCormick School of Engineering. “This…

MU Engineering professor helps solidify new bridge inspection standards

In July of 2018, FHWA issued guidance allowing the use of a risk-based analysis process to identify eligible bridges. Mizzou Engineering Professor Glenn Washer’s research influenced that decision. Mizzou Civil and Environmental Engineering Professor Glenn Washer has long been a proponent of more common-sense, risk-based federal bridge inspection standards, and he’s done the research to back them up. And now, those standards have become federal policy. Since 1967, all bridges must be inspected fully every two years per federal law.…

MU Engineering faculty takes smart cities research to new heights

Smart cities are on the rise. Smart sensing systems and associated data analysis frameworks play a key role in development of smart cities. Mizzou Engineering faculty are leading the way in this realm, and the Civil and Environmental Engineering Department has the accolades to prove it. Alavi The more the researchers study the potential of integrating smart sensors and data analytics to properly manage civil infrastructure systems, the more necessary a book became. In this arena, Assistant Professor Amir Alavi…
