Professor Publishes Paper on Finite Element Method

shell1MJ Cloud has coauthored “Finite element method in equilibrium problems for a nonlinear shallow shell with an obstacle” in the International Journal of Engineering Science. The paper, cowritten by LP Lebedev and FE Ponce-Vanegas (both of the National University of Colombia), employs a weak setup to justify application of the finite element method to the equilibrium problem for a nonlinear model of a shallow shell clamped along part of an edge constrained by a frictionless obstacle. It appears in a special issue of the journal, dedicated to Prof LM Zubov on the occasion of his 70th birthday.

A Dozen NSF Power Engineering Scholarships Awarded; More Available

huaScholarships 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.

ECE Professor Authors Journal Paper on Image Segmentation

Dr Umasankar Kandaswamy and colleagues from Washington University St Louis have had a paper accepted for publication in the Journal of Neuroscience Methods. The paper, entitled “Automated condition-invariable neurite segmentation and synapse classification using textural analysis-based machine-learning algorithms”, describes a fully automated machine-learning approach to high-resolution live-cell imaging studies. The present lack of such tools, which can handle varying image acquisition conditions, represents a challenge in biomedical image analysis (which must otherwise be performed manually by physicians, at great cost). The new algorithm is shown to be accurate and to maintain its performance levels under a wide range of image acquisition conditions. Congratulations to Dr Kandaswamy on an interesting and significant publication!

Professor Coauthors Book on Engineering Mathematics

Dr Michael Cloud has coauthored the second edition of Functional Analysis in Mechanics, a title in the Springer Monographs on Mathematics series. The first edition of the book, published by Springer in 2002, was written by Leonid P Lebedev (a mathematician and mechanicist at the National University of Colombia) and Iosif I Vorovich (deceased, formerly of Rostov State University, Russia, and a member of the Russian Academy of Sciences). The new 316 page book offers a brief, practically complete, and relatively simple introduction to applied functional analysis. It should be of interest to researchers, graduate students, and practicing engineers.

Smart Blood Glucose Meter

Article and graphics submitted by Dr. Umasankar Kandaswamy.

On a certain level, almost everyone is acquainted with the fact that self-blood-glucose measurement is an intrinsic and important part of a diabetic patient’s healthy life. However, only 17 million of us fully understand how heavily “living a near normal life” for a diabetic patient depends on “how effectively one can control and regulate” his or her blood glucose level. In other words, nearly 6% of the US population must self-measure the blood glucose level on a regular basis — in most cases several times a day — and adjust the insulin therapy accordingly (click here for further information on diabetes and its impact).

Since its introduction in 1970, the concept of self-measurement has grown from an obscure visual evaluation method requiring a large volume of blood (up to 25 microliters), to the use of fast and reliable electronic systems, referred to as blood glucose meters, that use electrochemical test strips to quantify blood glucose levels. Even though several types/brands of meters are commercially available for self-measurement — with options ranging from “smallest volume of blood needed” to “least amount of time taken” — no existing meter supports the option of interoperability. Simply put, if we buy a particular brand of test meter, we are forced to buy that brand’s test strips all the time. In most cases patients must endure an extensive period of trial and error before figuring out which meter/test strip combination is cost effective, easy to use, reliable, long lasting, and portable. To solve this problem, my students Kevin Mason (Electrical and Biomedical Engineering) and Zeran Gu (Mechanical Engineering) are working with me to develop a next generation smart blood glucose meter that is highly interoperable and convenient. In addition, the smart blood glucose meter is designed for compatibility with all types of mobile devices (e.g., iPad, iPhone, Android, Tablets).

The heart of the Smart Blood Glucose Meter is an electronic system called a transimpedance amplifier, which senses the electrochemical current (70 – 120 microamperes) produced by the glucose-induced reaction in a test strip and converts it to a readable voltage output (0 to 2.5V). Figure 1 shows a typical response of a transimpedance amplifier constructed in our LTU lab.

Figure 1. Quantifying glucose variation using One-touch-ultra test strip.

T1 instant (shown in Figure 1) is when the glucose is introduced at the test strip. After a so-called incubation period (the time period between T1 and T2), the output voltage of the amplifier starts to change in proportion to the rate at which gluconolactone (a resultant of the reaction between glucose and a mediator) is produced, thus relating the rate of change of the output voltage to the glucose concentration present in the test strip. Figure 2 shows the rate of change of the output voltage from the transimpedance amplifier for glucose concentrations ranging between 10 mg/dL to 400 mg/dL.

Figure 2. Change in glucose concentration impacts the rate of electrochemical reaction.

It can be observed that different glucose concentration levels produce output responses with distinct rise times, establishing a strong correlation between the glucose driven electrochemical reaction and the observable output voltage. Figure 3 shows the change in rise time (in seconds) for different values of glucose concentration and for three types of commercially available test strips: One-touch Ultra, Agamatrix, and Accu-Check. Experimental data shown in Figures 2 and 3 are average responses of three different sets of data collected by Kevin Mason during Spring and Summer 2012 using Electronic Explorer Kit and the Diligent-Waveforms software package.

Figure 3. Variation in rise time measured in seconds for different values of glucose concentration. (A) One touch ultra, (B) AgaMatrix, (C) Accu-Check.

Starting this Fall, students will be working on Phase II of the project. Phase II would involve finalizing the communication protocol (through which the transimpedance circuitry and mobile devices will communicate with each other), and developing an android/iPhone app through which the user will be able to access the device. Figure 4 shows the 3D rendering of the Smart Blood Glucose Meter designed by Natalie Haddad (student of College of Architecture, makeLab).

The book’s preface states that “The present text offers rigorous insight and will enable an engineer to communicate effectively with the mathematicians who develop models and methods for machine computation. It should prove useful to those who wish to employ modern mathematical methods with some depth of understanding.”

Robust Adaptive Software Radio Communication System

Dr Kun Hua and student Robert Reichel in the LTU Wireless Communication Lab.

Article by Dr Kun Hua

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.
