Dr. Bodine and Assistive Technology Partners featured in CU Connections

bodineAlthough Assistive Technology Partners (ATP)  is a program of both CU Anschutz (the School of Medicine) and CU Denver (the College of Engineering and Applied Science), it is located on neither campus. In a low-slung building at East 18th Avenue and Pearl Street in Denver, 15 faculty, staff and students – including engineers, clinicians, therapists and educators – transform lives and society every day.

They are led by the boundless energy of Executive Director Cathy Bodine, PhD, CCC-SLP, who has been with the organization for 18 years and can remember when it operated with a single grant and four people.

Professor Lewis discusses internet reputations with 9News

Jason Lewis, a computer science professor at CU Denver, knows once a story makes its way online, it becomes virtually impossible to remove.

“It’s this black hole. It gobbles up everything. It never goes away,” he said. “There really is no true way to get something off of the internet.”

Study by Kim, Marshall and Pal says 2013 floods could have been less destructive

The severe flooding that devastated a wide swath of Colorado last year might have been less destructive if the bridges, roads and other infrastructure had been upgraded or modernized, according to a new study from the University of Colorado Denver.

“People need to understand the importance and seriousness of infrastructure,” said Jimmy Kim, associate professor of civil engineering and lead author the study. “There is an assumption that a bridge will stand forever and that’s simply not true.”

Kim along with co-authors Wesley Marshall, and Indrani Pal, both assistant professors of civil engineering, examined the causes of the flooding and its impact on infrastructure.

The stage was set for the deluge when an unusual low pressure system generated a steady plume of monsoonal moisture flow from the Pacific Ocean toward Colorado’s Front Range communities.

The rain began on Sept. 9, 2013 and didn’t stop until the 16th. In just days, places like Boulder County received three-quarters of its yearly precipitation, the study said. Bridges collapsed, roads failed and homes were swept away.

According to the study, 120 bridges now need structural repair. Many were damaged by rushing water which washed out backfill soil and exposed bridge foundations.

Kim said new `scour control’ methods, aimed at reducing these washouts, should be developed to help bridges withstand future flooding.

“You can do that by upgrading existing piers (columns) supporting the bridge or changing current design approaches” he said. “The Colorado Department of Transportation is currently working on improving scour design for bridge structures.”

The researchers also suggested improving roads made of concrete or bituminous material like asphalt since they often disintegrate when flooded. Kim said fiber, nano-particles or polymeric admixtures could be added to these construction materials to increase tensile strength and flexibility while reducing cracking.

The study noted the successful use of geographic information systems (GIS) to help supply up-to-the-minute mapping and alerts about flood damage.

“The production of such data and maps extended well beyond the typical GIS community and included local news affiliates and even the City of Boulder itself,” said study co-author Wesley Marshall.

For example, on September 27, 2013, Boulder launched a `Community Flood Assessment’ crowd-sourced map using the Crowdmap application. The city asked users to submit flood reports via the website or smartphone apps. They were also asked how deep the flooding was and if they lost power. Video and photos could be uploaded to locate the event on an interactive map.

“Such efforts were not only useful during the recovery efforts but will continue to be used toward helping increase the resiliency of Colorado during such events,” Marshall said.

Overall, the researchers revealed a much wider problem.

From 1980 to 2007, about 90 percent of all global disasters were caused by flooding either by rain, tsunami, hurricane or some other natural event.

At the same time, the American Society of Civil Engineer’s 2013 Report Card for America’s Infrastructure gave the country a dismal D+. The group said $3.6 trillion was needed by 2020 to address the most serious problems.

In Colorado, the report card says, 70 percent of major roads are poor or mediocre and 566 bridges are structurally deficient.

“Reconstruction is very expensive and should be the last resort,” Kim said. “But we can repair or strengthen existing systems less expensively. We are looking at a growing national problem, one that will only get worse if we ignore it.”

The study was published last week in the Proceedings of the Institution of Civil Engineers.

This research was also featured on Channel 7 News and Colorado Public Radio.

According to a new study co-authored by Wesley Marshall, assistant professor of civil engineering, America’s streets are designed and evaluated with a an inherent bias toward the needs of motor vehicles, ignoring those of bicyclists, pedestrians, and public transit users. His study was featured in CU Today and on 9News and published in the Institute of Transportation Engineers Journal.

“The most common way to measure transportation performance is with the level-of-service standard,” said Marshall. “But that measure only tells us about the convenience of driving a car.”

Shandas among three to share patent for new smart material

The CU Technology Transfer Office is pleased to announce that researchers from CU’s Boulder, Anschutz and Denver campuses have been awarded a patent for improved shape memory polymers, a ‘smart material’ used in many next-generation implantable medical devices. The inventors on the patent are Christopher Bowman (CU-Boulder, ChBE), Robin Shandas (CU Denver, Bioengineering; CU Anschutz, Pediatrics; Children’s Hospital), Devatha Nair (CU Anschutz, Ophthalmology; former ChBE postdoc) and former ChBE research associate Neil Cramer.

U.S. 8,846,777, “Thiol-vinyl and thiol-yne systems for shape memory polymers,” was issued on September 30, 2014, and is part of a large portfolio of related patents prosecuted by TTO on behalf of CU.

Join us in congratulating these researchers on their achievement.

CEM class makes a site visit

IMG_0859On September 17, 2014, 17 students enrolled in Construction Materials and Methods, along with several faculty and graduate students from the Construction Engineering and Management program, made a site visit to the Cherry Creek Bridge Deck Replacement Project.  The project, at the corner of Cherry Creek and University, is slated for completion before Thanksgiving and is under the supervision of Kevin Rens, chair of civil engineering and director of construction engineering and management. Student observed many site conditions including the partial completion of two lanes of traffic, the debris catchment system, and epoxied rebar primed for the upcoming closure pour.
