Detection of Anthropogenic Signals of Below Thermal Noise Power

Rodger D. De Roo, Ph.D. Asst Scientist & Lecturer Department of Atmospheric, Oceanic and Space Sciences University of Michigan

Space-borne microwave radiometry is a technique for global measurement of geophysical parameters like snow pack depth, sea surface temperature, sea surface salinity, and soil moisture. However, radio frequency interference (RFI) is a major problem for microwave radiometers, especially at the longer wavelengths in the L- through X-bands. As this RFI is always additive, the presence of undetected RFI can bias the geophysical parameter retrieval. As radiometers have the most sensitive receivers operating in their band, low levels of RFI are both significant and difficult to identify. New space borne radiometers operating in these bands are being developed, such as for the Soil Moisture Active and Passive (SMAP) mission. Digital reception of the pre-detected IF signal has been demonstrated to have great ability to permit the detection of many forms of RFI. For example, with the calculation of the kurtosis statistic of the IF signal, continuous wave RFI and radar-like pulsed RFI can be distinguished, and the potential exists for detecting the pulsed RFI at levels comparable to a radiometer s noise equivalent radiometric uncertainty (NEDT). This presentation will describe the use of the kurtosis statistic to identify RFI in radiometric signals.

Sensor Interfaces: Interfacing with Human Body

Dr. Selcuk Talay

Sensors provide environmental information from the physical world that we live in to the electronic circuits that we have the processing power. Whether it is digital or analog processing afterwards, interfacing the sensors with the electronic circuits introduces stringent constraints such as ultra low-power consumption, excellent noise performance and accurate acquisition of the signals from the sensor node. Thus, interface circuit design requires advanced circuit and system level design techniques depending on the sensor type. This talk will cover different types of sensor interface circuits such as low-noise, low-power amplifier for bio-potential recording system and low-power, multi-path, complex, bandpass sigma-delta ADC circuit for body area networks. The main focus will be on the sensor interface design challenges and novel solutions.

A Hierarchical Framework for Audio Forensics

Dr. Hafiz Malik, Assistant Professor, Electrical and Computer Engineering Department, University of Michigan - Dearborn

The use of digital media (audio, video, and images) as evidence in every sector of litigation and criminal justice is becoming the norm. For digital media to be admitted as evidence into a court of law, its authenticity and integrity must be verified. This requirement is a complex and challenging task, especially if there are no helping data, such as digital watermarks or fingerprints, and if the media is only available in a compressed format. The availability of powerful, sophisticated, and easy-to-use digital media manipulation tools has made authenticating the integrity of digital media even more difficult. In this context, digital media forensics aims to determine the underlying facts about an evidentiary recording and to provide authoritative answers to various questions, such as the following:

  1. Was an evidentiary recording 'original' or was it created by splicing multiple recordings?
  2. What are the types and locations of forgeries, if there are any, in an evidentiary recording?
  3. Was the evidentiary recording captured using acquisition device X at location L, as claimed?
  4. Was the evidentiary recording captured using an acquisition device manufactured by vendor X or vendor Y?
  5. Is the (auditory/visual) scene in evidentiary recording original or was it digitally altered to deceive the viewer/listener?
This talk first surveys state-of-the-art in digital audio forensics and highlight limitations of the existing audio forensics method. This talk then presents a component-based solution to the general problem of audio forensics. In this talk, I will also highlight key problems in multimedia forensics ranging from detecting forgeries in digital recordings to unique mapping of digital recording to the acquisition device, recording environment identification, caller's privacy preservation, securing speaker verification (SV) systems against replay attacks, and recent findings in these areas.

Hafiz Malik is Assistant Processor in the Electrical and Computer Engineering (ECE) Department at the University of Michigan - Dearborn .

A Joint Model and SOC Estimation Method for Lithium Battery Based on the Sigma Point KF

Dr. ZhiWei He, Associate Professor, Hangzhou Dianzi University, Hangzhou, China, Department of Electronic and Information Engineering

Lithium-ion batteries have been widely used in electric vehicles (EV). The working state of the battery is very important to the safety of an EV. Online estimation of the state of charge (SOC) is essential in obtaining the battery working conditions. In order to achieve an accurate estimation of the SOC, the battery model should be adjustable when the battery is aged. A joint battery model and SOC estimation method based on the Sigma Point Kalman Filter (SPKF) is presented. A combined battery model is used to depict the relationship between the open circuit voltage (OCV) and the SOC of the battery. The main battery model parameter for estimation is the internal resistance and it is jointly estimated with the SOC online. Experimental results show that the SPKF based joint estimation method is effective.

Zhiwei received the B.S. Ph.D. degrees from Zhejiang University, China in 2001 and 2006, respectively, both in information and communication engineering.

Sliding Mode Observer Design for Robotics and Automotive Applications

Dr. Giscard Kfoury, Director, BS in Robotics Engineering Program, Lawrence Technological University

The implementation of efficient control schemes often requires the availability of accurate measurements of the state variables of the system. These measurements are usually not readily available due to reasons ranging from the high cost of sensors, to the lack of space or difficulty in mounting them, or simply due to inaccuracies in the measurements. As an alternative, estimators or observers can be designed to provide accurate estimates of the state variables appropriate for use by the controllers. The task of designing such observers can become very challenging when dealing with nonlinear systems, especially in cases where modeling uncertainties are present. This work presents various robust nonlinear observer designs based on the sliding mode or variable structure theory. These estimators are adequate for use with nonlinear systems that feature both parametric and structured uncertainties, and only require the knowledge of an upper bound on the modeling errors to produce accurate state variable estimates. Two applications are presented here: a design of a robust observer for a single-link flexible robotic manipulator, and a sliding mode observer design for a constrained single-cylinder engine crank-slider mechanism. Digital simulations are presented to assess the performance of the proposed designs.

Dr. Kfoury Joined Lawrence Technological University in 2008 as an assistant professor in the Mechanical Engineering department. He received a BEME from the American University of Beirut in 2001, a Master of Science in Mechanical Engineering from Wayne State University in 2003, and a Ph.D. in Mechanical Engineering from Wayne State University in 2008.

Smart Materials for Smart Microsystems

Dr. Nelson Sepúlveda

Microelectromechanical or nano-electromechanical systems (MEMS or NEMS, respectively) have demonstrated several advantages over the solid-state device counterparts in a broad spectrum of applications including radio-frequency systems and biomicrofluidics, but particularly in the highly multidisciplinary research area of transducers -i.e. sensors and actuators-. The evolution of micrometer sized transducers started with the fabrication of silicon pressure sensors in the 1960s and since then the efforts have been directed towards their miniaturization. With time, the technological advances allowed by this "miniaturization" research trend have been combined with the use of new materials, giving rise to very successful science-engineering research philosophies. Recent developments on smart materials have demonstrated to be capable of revolutionizing the field of micrometer sized transducers by allowing for new actuation mechanisms, and the abrupt -and simultaneous- change of multiple properties due to their multifunctional characteristics. Our group has reported a new and transformative technology based on vanadium dioxide (VO2) thin film coatings. We recently found that, in addition to the well-known changes in the electrical and optical properties of VO2 films, their mechanical properties also change abruptly during their solid-solid phase transition. This observation unveils a new operation principle for micrometer sized transducers, which is capable of overcoming the performance limitations imposed by the physical mechanisms that govern the currently state-of-the-art technologies in thermal- and optical-based micro-transducers (e.g. thermal expansion coefficient differences). After characterizing our VO2 thin films, we implemented this technology on laser- and thermal-actuated micrometer cantilevers, opto-electronic and all-optical multiple memory state devices, and tunable MEMS resonators.

Prof. Nelson Sepúlveda obtained his undergraduate degree in Electrical and Computer Engineering from the University of Puerto Rico, Mayaguez Campus in 2001 with honors. He completed his M.S. (2002 and PhD (2005) degrees in Electrical and Computer Engineering at Michigan State University. From January 2006 to June 2011, Dr. Sepúlveda was faculty at the University of Puerto Rico - Mayaguez, and during this time participated in several summer research programs for faculty at the Air Force Research Laboratories (2006 and 2007), National Nanotechnology Infrastructure Network (NNIN) (2008) and the Cornell Center for Materials Research (CCMR) (2009). In 2010, he was awarded the NSF Career award. His research interests are micro and nanometer-sized sensors and actuators (or transducers), characterization of smart and multifunctional materials and their integration in microsystems.
