Dr Nabih Jaber and his students Tahmina Gouhar, and Pallavi Kuntumalla have published a paper, entitled “Speech enhancement using new iterative minimum statistics approach” in the 2017 IEEE 30th CCECE conference.Abstract:In hands-free mobile communication, speech quality is often degraded due to presence of surrounding noise. This paper introduces an improved version of Minimum Mean Square Error (MMSE) noise estimator. Noise spectrum estimation is a crucial element used in speech recognition systems. Our proposed noise estimation method is based on a popular searching algorithm used in software engineering called Binary Search (BS), which we integrate with First-In First-Out (FIFO) MMSE noise reduction algorithm. In the literature, there is no research addressing the integration of BS algorithm with an active noise cancellation system. The noise spectral minima are computed using BS algorithm which makes it fast and efficient. The proposed algorithm is tested using real time data collected from vehicles running at different speeds. Simulation results are provided, and it is shown that the proposed algorithm outperforms other MMSE algorithms.
On Sunday, March 22nd 2015, The College of Management was proud to host ISACA’s 2nd Annual Cybersecurity Scholarship Case Competition. This year’s second place winner is a Computer Engineering undergraduate student, graduating in 2015.
Suvro Sudip, LTU computer engineering senior, won second place and $2500. He is invited to attend the April 22 ISACA dinner meeting where the winners will be formally recognized with certificates.

Lawrence Technological University incorporates the Society of Automotive Engineer’s Formula HybridTM competition into its engineering curriculum as a year-long project each year. This year’s competition is April 28 – May 1, 2014 at the New Hampshire Motor Speedway. The competition provides students a unique and wonderful opportunity to combine the University’s signature blend of theory and practice with the challenge of a real-world problem: creating a high-performance racing vehicle that is also fuel-efficient. The students design, build, test, and race a Formula hybrid vehicle in competition with other student engineering teams from around the world.
ECE undergraduate students Don Henderson and Peiyue Xu are critical components of this year’s project. Team Leader Adam Tallman and Electrical Lead Eric Onan have worked far beyond the normal hours with team members Jim Cass, Jake Ball, Jonathon Vitale, Mohamed Albira, Matt Moyer, Kingman Yee, and Nick Tallman to bring the vehicle to a level that will seriously challenge the pack for first place.
Featuring 17MJ expanded battery capacity, 35Kw electric motor, 250cc gas power plant and sophisticated dual mBed processor controllers, adding LCD touch screen energy and performance monitors, WiFi wireless telemetry and new CV transmission, this year’s team feels confident.
The display expert from China has been hard at work on the LCD display for the vehicle. The team finally has it up and running with communication to the controller, months before the competition!

Scholarships have been awarded to seven students at Lawrence Technological University and five at Monroe County Community College (MCCC) under a scholarship program funded by the National Science Foundation (NSF) to address the need for more engineers for the power industry.
The five MCCC scholarship recipients are expected to enroll at Lawrence Tech within the next year.
As a result, the full five-year grant of $598,000 for the Scholarship in Science, Technology, Engineering and Mathematics (S-STEM) program has been approved based on the results during the first year under the leadership of Assistant Professor Kun Hua of the Department of Electric and Computer Engineering.
Thanks to the NSF grant, Lawrence Tech is offering $10,000 scholarships for two years to community college graduates to complete a bachelor’s degree in electrical engineering with a power engineering concentration. Community college students working on their associate degree in this area also qualify.
Responding to an impending national shortage of power engineers needed for the nation’s electricity production plants and distribution system, last year NSF awarded LTU the five-year grant to provide scholarship assistance to students in this field.
Power engineers develop, maintain, and modernize “the Grid,” the vast network of transformers, generators, motors and electronics that supply electrical power.
LTU’s S-STEM scholarship recipients gain additional knowledge about the power industry from outside speakers, field trips and participation in professional organizations. Internships and job placement are also part of the scholarship program.
“LTU is leveraging its network of local and regional partnerships to aid in the recruitment, retention, and job placement of the S-STEM scholars,” said Hua, the S-STEM advisor.
One of those partners is DTE Energy, which has a specific need to hire more nuclear engineers for its Enrico Fermi Nuclear Generating Station near Monroe. DTE Energy worked with Monroe County Community College in developing the associate degree in nuclear engineering technology, and graduates of that program are eligible for the scholarship program to continue their studies at LTU.
