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.

Dr. Jaber, a Professor at the Electrical and Computer Engineering Department and Director of ISWiNLab, is looking for a very skilled programmer to develop an “App” for a home energy management system (HEMS) proposal that has already been fully designed by Dr. Jaber. The student research assistant will have all the high level design diagrams required to develop the final App. The project abstract/description is as follows.
Abstract — Consumer domain energy management systems or home energy management system (HEMS) is largely neglected in existing practical smart grid EMS studies. One of ISWiNLab’s projects proposes a practical HEMS that supports various existing and emerging actors. Some of the proposed features include the support of automatic and manual scheduling and control of the devices, continuous monitoring and efficient notification. The goal of the design is to achieve optimized performance under dynamic situations. For better understanding and implementation of the concepts behind Dr. Jbaer’s proposed design, detailed Use Case diagrams of the various actors and their functionalities will be provided to the successful candidate. A substantial amount of peak shaving/shifting is observed using the proposed application when tested in a simulator.

Dr. Nabih Jaber has coauthored a paper entitled “A quantitative real time data analysis in vehicular speech environment with varying SNR” in the 2016 IEEE 18th International Workshop on Multimedia Signal Processing (MMSP). The abstract is as follows:
The purpose of this paper is to compare the performance of two common filters operating on noisy speech recorded in automobiles travelling at various speeds. The filters are based on Spectral Subtraction (SS) and Kalman Filtering (KF). The literature contains studies based on simulated data whereas this paper uses real time data collected in car’s in search of an optimal solution. The comparisons were based on real recorded samples containing noisy speech signals with durations of approximately 2 minutes each. Different cases of noise levels which represent the most common situations experienced by drivers were created. The different settings used include varying car speeds (e.g., 40 mph, 70 mph), varying fan power, and window positions settings. The study was carried out using three different car models. The measured noisy voice signals were filtered using the different filtering techniques and the resulting filtered signals were compared in the time domain and the frequency domain, both quantitatively and psychometrically. Furthermore, the quantitative analysis approach was applied to the results for more accurate interpretation. Results show that SS outperforms KF in noise reduction, and with much less speech distortion at the different Signal to Noise Ratios (SNRs) tested. The audio test results subjected to human listening are comparable with the simulation results. Overall, SS showed superior performance over KF in vehicular hands-free speech applications.

The Holcombe Department of Electrical & Computer Engineering at Clemson University is seeking applicants for a summer Research Experiences for Undergraduates (REU) program. This NSF funded program is entitled: “REU Site: Solid-State Devices for Electronics, Photonics, and Magnetics Technology“. The REU supports up to 10 summer students, with one to four semesters remaining in their undergraduate programs, to become involved with a faculty member and graduate students for a 10 week research experience at Clemson. The program is open to undergraduate students in Electrical and Computer Engineering, Materials Science, Bioengineering, and Physics. Closely related disciplines may also be considered. The program provides summer housing on campus for the students and pays a generous stipend.
With a $50,000 grant, DENSO North America Foundation is underwriting a research effort that gives LTU undergraduates in mechanical engineering, electrical/computer engineering and civil engineering an interdisciplinary opportunity to develop mobile, wireless sensor networks (MWSN) to help keep drivers safer.
“An MWSN combines vehicle-to-vehicle and vehicle-to-infrastructure connectivity to give drivers 360-awareness of their surroundings,” said Kun Hua, professor of electrical/computer engineering. Along with James Mynderse, who teaches in the department of mechanical engineering, and Nishantha Bandara, who teaches in the department of civil engineering, he is coordinating three different research programs that include nearly 100 students. A number of courses and labs in all three departments will provide students with the knowledge needed to conduct the research.
According to the National Highway Traffic Safety Administration, 5.7 million traffic accidents occurred in 2013 resulting in more than 32,700 fatalities. Intelligent traffic systems, like the ones the students are developing, will improve safety. In addition, information about road conditions and traffic congestion that will be transmitted to drivers also could improve traffic flow and reduce fuel waste.
The grant will give the students hands-on development experience, help build an inter-disciplinary lab and purchase the equipment and supplies necessary for the projects.
Currently in development, the sensor networks are expected to be installed on test vehicles in the summer of 2016.
“Our students are not only learning valuable, marketable skills, but they have the satisfaction of knowing that what they’re creating may actually save lives in the future,” added Hua.

Dr Nabih Jaber has had a paper accepted by the International Journal of Vehicular Communications, published by Elsevier. The abstract of the paper, entitled “Passive Cooperative Collision Warning (PCCW) MAC designs for reliable vehicular safety messaging”, is as follows:
This paper presents – Passive Cooperative Collision Warning (PCCW), and enhanced-PCCW (EPCCW) protocol designs for safety message reception reliability improvement in Dedicated Short Range Communications (DSRC). PCCW and EPCCW employ a cooperative warning scheme for reduction of collisions, without increasing packet traffic. EPCCW utilizes the physical layer (PHY) properties to create sub-slots for the purpose of further increasing reliability by both avoiding and minimizing probability of collision at slots that would nominally fail. Full analytical derivation of the relative reliability and delay performances for both PCCW and EPCCW protocols is provided. An accurate and complete simulation model is used, which combines an accurate DSRC PHY, MAC and federated mobility model designed using the Simulation of Urban MObility (SUMO) model. Analytical and simulation results agree and show that PCCW and EPCCW protocols significantly improve reliability performance relative to the leading safety messaging protocols. Under high collision scenarios and at optimal number of repetitions, an improvement of up to 40% in reliability is observed, and up to 80% of improvement is achieved at higher load. Improvement in average timeslots delay is also observed that is well within acceptable delay threshold. Thorough simulation results of the proposed protocols are presented under varying message range, coding rates, modulation schemes, channel models, vehicular densities, safety message lifetimes, and transmission frequencies.

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.

The Wireless Communication Lab is now available for undergraduate senior projects and graduate class projects involving Software Defined Radio.
I am using seed grant funding to develop an adaptive and robust software radio communication system with my undergraduate and graduate students. The aim is to generate an automotive embedded system to scan commercial radio stations and automatically select a station that is currently playing music, sports, a talk show, weather information, etc. This would allow users to skip commercials and listen to preferred content continuously without having to manually scan for stations. The system is designed to perform real time analysis of an audio stream through pattern recognition, data mining, nonlinear optimization, signal processing, and embedded techniques. Features and more advanced adaptation algorithms can be implemented at a later stage. In the future, with just one click, you will be able to listen to all live local games — Red Wings, Lions, Pistons, Wolverines, Spartans — whether you are driving along the coast of California or skiing in rural Colorado.
