RIFAI

TO ENHANCE CYBERSECURITY

As the nature of digital warfare evolves, the need for a workforce trained in cybersecurity is critical for defending the United States from attacks. In response to the growing threat and the need for talent, the University of Houston has joined a consortium funded by the U.S. Department of Defense (DoD) to launch a vir tual institute that will recruit and train the next generation to combat cyber warfare, including cyber espionage and at tacks on the electromagnetic spectrum.

The virtual institute, called VICEROY (Virtual Institutes for Cyber and Electromagnetic Spectrum Research and Employ) DECREE, will be led by Northeastern University. It will offer a two-year scholarship program focused on advanced cyber security, the electromagnetic spectrum, cryptography, data science, DoD research and strategic foreign languages, in cluding Chinese, Russian, Arabic, Persian and Korean. The

program will be offered across five universities, including UH, Northern Arizona University, the University of Texas at Austin and the University of South Carolina, and will include experiential learning opportunities, such as co-op positions at the DoD and other employers within the consortium part ners’ networks.

“The VICEROY DECREE virtual institute consortium model is transformational. It brings together the best offerings from multiple institutions to meet the workforce training needs in these domains,” said Hanadi Rifai, Moores Professor of civil and environmental engineering and UH team lead on the project.

The scholarship program will fund 60 students and is open to veterans, ROTC students and civilians, with a particular emphasis on underrepresented minorities, women and those from economically disadvantaged backgrounds. Students eligible to enroll must be security clearance-eligible U.S. citizens.

KALLIONTZIS RECEIVES 2 GRANTS TO STUDY CONCRETE PERFORMANCE

A professor at the Cullen College of Engineering has received a pair of grants that will utilize the one-of-a-kind machinery available at the University of Houston to conduct research into shear failures for a new type of concrete, UHPC.

Dimitrios Kalliontzis, an Assistant Professor in the Civil and Envi ronmental Engineering Department, said the research will investigate the performance of structures using a new concrete material, Ultra-High-Performance Concrete (UHPC).

“UHPC is new to civil engineering and it is considered an emerging technology that promises to tackle aging effects and enhance the structures’ robustness and durability,” Kalliontzis said. “While UHPC is attracting significant attention from industry, the significant lack of experimental data hinders the development of design code pro visions. Without those provisions, there is no official guidance to the field implementation of UHPC structures. Our two research proj

ects will generate the necessary data to support the development of provisions for the design of UHPC against shear failures.”

Kalliontzis noted that the American Concrete Institute (ACI) and Precast / Prestressed Concrete Institute (PCI) chose UH for the re search because of the unique hardware present at the Cullen Col lege of Engineering.

“What’s important about this research is that it leverages the Uni versal Panel Tester, a one-of-its-kind machine in the United States, which is located in the Structural Research Laboratory of University of Houston,” he said.

The ACI and PCI research will span three years, with funding of about $100,000. Additional material and product support will be provided by industry partners, including Steelike and Tindall.

ASSESSING FLOOD RISKS USING RADAR TECHNOLOGIES

With a $675,000 grant from NASA, researchers at the Univer sity of Houston’s Cullen College of Engineering and the University of California, Irvine are launching a new flood risk assessment project focusing on sandy beaches and dunes.

Pietro Milillo, Assistant Professor of Civil and Environmen tal Engineering, will work on the research with Brett Sand ers, UCI Professor of Civil and Environmental Engineering. Together, they will develop new observational strategies and techniques to measure sandy beaches and dunes, and use technologies like interferometric synthetic aperture radar and lidar, which involves targeting an object with laser light to obtain precise size and distance measurements.

In an early phase of the project, the team will data provided by the German Aerospace Center’s TanDEM-X and NASA’s IceSAT-2 satellites with surface elevation models and lidar observations at four beach/dune sites in Southern California.

The researchers will conduct measurements on a monthly and in some cases sub-monthly basis for three years.

The team will seek answers to several key questions, includ ing: How can large-scale geological hazards be accurately forecast in a socially relevant timeframe? How will local sea level change along coastlines around the world in the next decade to century? And what processes and interactions de termine the rates of landscape change?

ROBERTO BALLARINI

HONORED AS ASME FELLOW

Roberto Ballarini, Thomas and Laura Hsu Professor and Department

Chairman of Civil and Environmental Engineering, has been honored with election to the Fellow grade of membership for the American Society of Mechanical Engineers (ASME). Only about 3,000 members of ASME are Fellows, out of a total membership of about 75,000.

BELARBI EARNS AMERICAN CONCRETE INSTITUTE SERVICE AWARD

A Cullen College of Engineering profes sor has been recognized for his distin guished service with the American Con crete Institute (ACI).

Abdeldjelil “DJ” Belarbi, Ph.D., Hugh Roy and Lillie Cranz Cullen Distinguished Professor in the Civil and Environmental Engineering Depart ment, is one of the recipients this year of the Delmar L. Bloem Distinguished Service Award. He is the first University of Houston professor to receive the honor.

The Distinguished Service Award was established in 1969 to rec ognize noteworthy work on ACI technical committees. The name of the award was changed to the Delmar L. Bloem Distinguished Service Award in 1972 in honor of the late Bloem. The award is given to a current or recent chair of an ACI technical committee, or under special circumstances, to deserving individuals other than committee chairs, in recognition of outstanding performance.

Belarbi has been an active member of ACI since 1989 and has served in several national and international technical and educa tional committees. During the last three decades, he held several officer positions within ACI and chaired several technical committees. As a member of ACI-440 committee (Fiber-Reinforced Polymers Reinforcement), he co-authored several technical doc uments on the subject. Belarbi served as the Chair to the Joint ASCE-ACI-445 committee (Shear and Torsion) for seven years and under his leadership, he led the development of a technical doc ument on torsion of structural concrete.

As part of his ASCE-ACI 445 chairmanship and more recently, Be larbi led an international effort to assess and revise the current shear design procedures for reinforced concrete. This exercise re sulted in revised design equations that were implemented in the 2019 ACI Building Code (ACI318-19). Belarbi’s leadership and team effort were recognized by him receiving the 2019 nVent Lenton Award, and now, this 2022 Delmar L. Bloem Award.
