The Center for Advanced Computation and Telecommunications (CACT) is a collective of students, faculty and alumni striving to engage and support a diverse group of researchers and educators in engineering and science.

CACT was created in 1990 by Professors Charles Thompson and Venkatarama Krishnan from the Department of Electrical and Computer Engineering with a vision to support students and faculty in interdisciplinary research, education and service. Our research focus is on computational modeling of acoustic, communications and stochastic systems. In the last three decades, over two hundred students from CACT have graduated with degrees in Electrical, Computer Engineering and Computer Science gaining experience in undergraduate and graduate research. The Center promotes the engagement of students in community service and supports their development as mentors and role models.

Current Projects

Thompson and Denis Edit Special JASA Issue on Acoustofluidics

The Acoustical Society of America, will publish in 2021 a JASA Special Issue that seeks to address the fundamental science impacting the application of acoustically driven fluid motion. Guest Editors: James Friend (UCSD), Charles Thompson (UML), Kedar Chitale (FloDesign Sonics) and Max Denis (UDC).

New JASA publication presents a model for the Great Seal Bug, the 'Thing'

In 1960, U.S. Representative to the United Nations Henry Cabot Lodge Jr. points to the spot on the U.S. Great Seal (a 1945 gift from the Soviets that hung in Spaso House for decades) where it had been bugged, providing proof of Soviet espionage to the U.N. Security Council. The Theremin device inside was activated by external electromagnetic signals, making it difficult to detect.

In this paper entitled, Analysis of a passive radio frequency excited acoustic transducer, authors Hu, Thompson, Remillard and Chandra model the physical processes that govern the operation of a passive acoustic transducer. Research models the Great Seal Bug or the ‘Thing’ which was hidden in the US embassy inside the seal of the US by the Soviet Union in 1945.

Collaborative Research on Future of Work using Augmented Reality

Microsoft HoloLens 2 is an augmented reality headset developed and manufactured by Microsoft on a table with a monitor in the background.

This research explores the role of AI-Assisted Augmented Reality systems in training future workforce, improving inter-generational communications, and sharing knowledge across disciplines. The team from UMass Lowell, University of Akron and Ohio State University will apply tools from Participatory Action Research to hone research questions and design workflow processes.
