“Macro Impacts with Micro Technologies:  Toward Distributed Environmental Monitoring via Pervasive Electronics”

“Macro Impacts with Micro Technologies: Toward Distributed Environmental Monitoring via Pervasive Electronics”

January 1st, 2015

“Macro Impacts with Micro Technologies: Toward Distributed Environmental Monitoring via Pervasive Electronics”By Dr. Hanseup Kim, USTAR Assistant Professor, Electrical & Computer Engineering Dept., University of Utah Monday, January 12, 2015 at 3:05 p.m. in WEB 1230 Abstract Numerous unknown physical and chemical phenomena can be precisely analyzed by highly-accurate electro-mechanical, chemical and biological transduction mechanisms in micro and nano scales, impacting broad contexts of human life. Air quality, an emerging societal issue, is known to cause the fatalities that are twice the number of automobile fatalities in US and that are equal to deaths from breast cancer and prostate cancer combined. Hundreds of scientific studies conducted worldwide have provided evidences that polluted air has alarming adverse effects on health. Clearly, the exposure to air pollution needs to be monitored for individuals. Traditionally air quality has been measured at the community-level relying on a limited number of fixed monitoring stations (e.g. only five stations in Philadelphia), failing to model individual risks. This can be best addressed by developing a miniaturized air-quality monitoring system in a portable and wearable form, which can be enabled by micro/nano technology. This talk discusses the challenges and recent milestones in miniaturizing a gas chromatography (GC)-based air quality monitoring system in order to enable personal-level evaluation of air quality. Specifically, this talk will discuss the scientific and engineering innovations in individual MEMS components of the integrated micro GC system. Such components include (1) micro actuators for efficient pumping of compressible gases, (2) a chemical separation technique exceeding the conventional state-of-art limit, and (3) a micro chemical sensor that is time-invariant. Future directions will be also discussed for personalized in-vitro analysis of the health impact of air pollutants by developing a “microGC to lab-on-chip” platform technology.

"Implantable and Wearable Microelectronic Devices to Improve Quality of Life for People with Disabilities"

January 7th, 2015

"Implantable and Wearable Microelectronic Devices to Improve Quality of Life for People with Disabilities" Maysam Ghovanloo, Ph.D. GT-Bionics Lab, School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA, USA Monday, January 26, 2015 3:05 pm WEB 1230 Abstract Implantable microelectronic devices (IMD) and neuroprostheses are finding applications in new therapies thanks to advancements in microelectronics, microsensors, RF communications, and medicine, which have resulted in embedding more functions in IMDs that occupy smaller space and consume less power, while offering therapies for more complex diseases and disabilities. I will address how we are pushing the limits on developing key building blocks for state-of-the-art IMDs, particularly on the analog front-end, RF back-end, and power management. IMDs have been quite successful in neuroprosthetic devices, such as cochlear implants and deep brain stimulators. They are also being considered for brain-computer interfacing (BCI) to enable individuals with severe physical disabilities to control their environments, particularly by accessing computers. Implantable BCIs, however, are highly invasive and it is not clear whether end users would accept them in presence of less invasive alternatives. At the GT-Bionics lab, we pursue implantable BCIs as advanced tools for neuroscience research on small freely behaving animal subjects. An example of these applications is a smart cage, the EnerCage, which can wirelessly power, communicate with, and track electronics implanted in or attached to small freely behaving animals. At the same time, we are exploring novel minimally-invasive methods for individuals with severe paralysis to make the best use of their remaining abilities to control their environments. An example of such technologies is a wireless and wearable brain-tongue-computer interface (BTCI), also known as the Tongue Drive System (TDS), which enables individuals with tetraplegia to control their environments using their voluntary tongue motion. We are also working on wearable devices that help the elderly to comply with their prescribed medication regiments and notify the emergency unit in the event of a fall.

“Trustworthy Integrated Circuit Design”

"Trustworthy Integrated Circuit Design"

February 9th, 2015

Abstract Designers use third-party intellectual property (IP) cores and outsource various steps in their integrated circuit (IC) design and manufacturing flow. As a result, security vulnerabilities have been emerging, forcing IC designers and end-users to reevaluate their trust in ICs. If an attacker gets hold of an unprotected IC, attacks such as reverse engineering the IC and piracy are possible. Similarly, if an attacker gets hold of an unprotected design, insertion of malicious circuits in the design, and IP piracy are possible. To thwart these and similar attacks, we have developed three defenses: IC camouflaging, logic encryption, and split manufacturing. IC camouflaging modifies the layout of certain gates in the IC to deceive attackers into obtaining an incorrect netlist, thereby, preventing reverse engineering by a malicious user. Logic encryption implements a built-in locking mechanism on ICs to prevent reverse engineering and IP piracy by a malicious foundry and user. Split manufacturing splits the layout and manufactures different metal layers in two separate foundries to prevent reverse engineering and piracy by a malicious foundry. We then describe how these techniques are enhanced by using existing IC testing principles, thereby leading to trustworthy ICs.

Electronic, Optical and Magnetic Materials for Neural Interrogation Dr. Polina Anikeeva, Career Development Professor, Department of Materials Science and Engineering Massachusetts Institute of Technology Monday, February 23, 2015 3:05 – 3:55 p.m. SMBB 2650 Abstract The mammalian nervous system is often compared to an electrical circuit, and its dynamics and function are governed by ionic currents across the membranes of neurons. Many neurological disorders are characterized by inhibited/amplified neural activity in a particular region or lack of communication between the two regions of the nervous system. Current approaches to treatment of these disorders have limited effectiveness, and often rely on mechanically invasive and bulky devices. There is a pressing need for biocompatible materials and devices allowing for precise minimally invasive manipulation and monitoring of neural activity. In Bioelectronics Group, we are taking two complimentary materials approaches to neural recording and stimulation: (1) Flexible polymer and hybrid optoelectronic fibers for intimate neural interfaces; (2) Magnetic nanomaterials for minimally invasive manipulation of neural activity. In my talk, I will illustrate how a fabrication process inspired by optical fiber production yields flexible multifunctional probes capable of optical, electronic and pharmacological interfaces with neural tissues in vivo. I will then demonstrate how these fiber-based neural probes can be tailored to applications within a specific part of nervous system such as the brain or spinal cord. Finally, my talk will cover materials synthesis and physics that enable minimally invasive neural stimulation via functional fusion of magnetic nanomaterials and ion channels on neuronal membranes. I will describe applications of the remote magnetothermal paradigm in stimulation of intact brain circuits, and illustrate how materials design can enable multiple interrogation modalities with alternating magnetic fields.

“Analysis of Sub-synchronous Resonance in Wind Farms Interfaced with Series Compensated Transmission Lines”

"Analysis of Sub-synchronous Resonance in Wind Farms Interfaced with Series Compensated Transmission Lines"

February 20th, 2015

"Analysis of Sub-synchronous Resonance in Wind Farms Interfaced with Series Compensated Transmission Lines" Dr. Hossein Ali Mohammadpour, Postdoctoral Fellow, University of South Carolina Mon. March 9th, 2015 from 3:05 – 3:55 p.m. in WEB 1230 Abstract Nowadays, it is well-understood that the burning of fossil fuels in electric power stations has a significant influence on global climate due to greenhouse gas emissions. In many countries, the use of cost-effective and reliable low-carbon electricity energy sources is becoming an important energy policy. Among different kinds of clean energy resources- such as solar power, hydro-power, ocean wave power and so on, wind power is the fastest-growing form of renewable energy at the present time. The adjustable speed generator wind turbine (ASGWT) has key advantages over the fixed-speed generator wind turbine (FSGWT) in terms of reduced mechanical stress, improved power quality, high system efficiency, and reduced acoustic noise. One important class of ASGWT is the doubly-fed induction generator (DFIG), which has gained significant attention from the electric power industry due to its advantages over the other class of ASGWT, i.e. fully rated converter-based wind turbines. Because of increased integration of DFIG-based wind farms into electric power grids, it is necessary to transmit the generated power from wind farms to the existing grids via transmission networks without congestion. Series capacitive compensation of DFIG-based wind farm is an economical way to increase the power transfer capability of the transmission line connecting the wind farm to the grid. However, a factor hindering the extensive use of series capacitive compensation is the potential risk of sub- synchronous resonance (SSR). The SSR is a condition where the wind farm exchanges energy with the electric network, to which it is connected, at one or more natural frequencies of the electric or mechanical part of the combined system, comprising the wind farm and the network. The frequency of the exchanged energy is below the fundamental frequency of the system. This phenomenon may cause severe damage in the wind farm, if not prevented, as occurred in the ERCOT power transmission network event of 2009, which damaged both wind generators and the series capacitors. This seminar deals with the SSR phenomena in a capacitive series compensated wind farm. A DFIG-based wind farm, which is connected to a series compensated transmission line, is considered as a case study. The small-signal stability analysis of the system is presented, and the eigenvalues of the system are obtained. Using both modal analysis and time-domain simulation, it is shown that the system is potentially unstable due to the SSR mode. Then, two different possibilities for the addition of SSR damping controller (SSRDC) are investigated. The SSRDC can be added to (1) gate-controlled series capacitor (GCSC), or (2) DFIG rotor-side converter (RSC) and grid-side converter (GSC) controllers. The first case is related to the series flexible AC transmission systems (FACTS) family, and the second ca     se uses the DFIG back-to-back converters to damp the SSR. The SSRDC is designed using two methods including (1) residue-based analysis suppo

“Transparency and Data-Driven Operation in Smart Grids”

"Transparency and Data-Driven Operation in Smart Grids"

February 21st, 2015

"Transparency and Data-Driven Operation in Smart Grids" Dr. Reza Arghandeh, Postdoctoral Scholar, University of California – Berkeley Fri. March 13th, 2015 3:05 – 3:55 p.m. WEB 1230 Abstract The smart grid revolution is creating a paradigm shift in distribution networks that is marked by significant intermittency and uncertainty imposed by distributed energy resources on power systems. Distribution networks historically are lagging behind transmission networks in terms of observability, measurement accuracy, and data granularity. Grid modernization dramatically increases the need for tools to monitor and manage distribution networks and microgrids in a fast, reliable, and accurate fashion. Development of data-driven approaches to support required visibility and operational analytics is key to providing substantial enhancement in any societal scale infrastructure, e.g. electric grids. Visibility may allow us to anticipate imbalances and disturbances before they actually occur, giving us more time to prepare and respond. Measurement data analysis will allow for the visualization of power networks on multiple spatial and temporal scales. This talk will address opportunities and challenges of developing and implementing advanced monitoring technologies and data-driven decision making tools to support distribution network operation and control. Monitoring tools, such as phasor measurement units (PMUs), which have had success in the transmission system are ideal candidates for distribution network and microgrid applications. This talk will provide an overview of an ARPA-E funded research effort by UC Berkeley and the Lawrence Berkeley National Lab to build a network of high-precision micro-synchrophasors (µPMUs) and develop applications for µPMU data. Two keystones for distribution network transparency are the physical topology detections and the state estimation tools, which will be discussed in this talk. It is not practical to directly measure all parameters at every network component due to operational and economic constraints. Developing optimal state estimation algorithms, in addition to topology detection, is crucial in order to extract principal network behaviors from a limited number of measurements. Speaker Biography Dr. Reza Arghandeh has been a postdoctoral scholar at the University of California, Berkeley’s California Institute for Energy and Environment since 2013. He has 5 years industrial experience in power system working with different utilities. He completed his Ph.D. in Electrical Engineering with a specialization in power systems at Virginia Tech.

“Nanosystems Design and Tools”

"Nanosystems Design and Tools"

February 22nd, 2015

"Nanosystems Design and Tools" Dr. Pierre-Emmanuel Gaillardon, Research Associate, Laboratory of Integrated Systems, Swiss Federal Institute of Technology - EPFL Mon. March 30th, 2015 from 3:05 – 3:55 p.m. in WEB 1230 Abstract Nanosystems are integrated systems exploiting nanodevice technologies. Nanodevices are either advanced Complementary-Metal-Oxide-Semiconductor (CMOS) transistor technologies or disruptive beyond-CMOS alternatives that can replace or enhance pure silicon technologies. The broad objective of this talk is to study circuits, architectures and design tools which, based on a deep understanding and abstraction of the technologies, allow us to realize nanosystems that outperform current integrated systems in terms of capabilities and performance. In the first part of the talk, I will introduce a novel class of computation devices, based on current silicon technology, which exhibit a controllable-polarity property. Controllable polarity devices enable a compact realization of XOR/MAJ-based logic functions, which are not implementable in CMOS in a compact form. In the second part of the talk, I will present emerging logic synthesis techniques, which can achieve native support for emerging nanoprimitives and extend the performances of current technologies. Two novel logic representation forms that show superior performances in manipulating logic functions will be discussed. In addition, I will show how their expressiveness can be leveraged in the design of Field Programmable Gate Arrays (FPGAs) architectures. In the final part of the talk, I will explain how we exploited the unconventional physical properties offered by Resistive memories (RRAMs) in FPGAs. Instead of only employing RRAMs as pure memories, we extended their use to that of non-volatile switches and we designed innovative circuits for routing elements, in which the memories take integral part in the data path. This approach is expected to lead to a breakthrough in the field of high performance reconfigurable platforms demonstrating more density, a higher performance and a better energy efficiency.

“Evolution of Microwave and Millimeter Wave Imaging for NDE Applications”

"Evolution of Microwave and Millimeter Wave Imaging for NDE Applications"

February 23rd, 2015

“Evolution of Microwave and Millimeter Wave Imaging for NDE Applications” By Dr. Reza Zoughi, IEEE Distinguished Lecturer in Instrumentation and Measurements, Schlumberger Endowed Professor, Missouri University of Science and Technology Friday, April 17th, 2015 from 3:05 – 3:55 p.m. in WEB 1230 Abstract Millimeter-wave signals span the frequency range of 30 GHz to 300 GHz, corresponding to a wavelength range of 10 mm to 1 mm. Signals at these frequencies can easily penetrate inside dielectric materials and composites and interact with their inner structures. The relatively small wavelengths and wide bandwidths associated with these signals enable the production of high spatial-resolution images of materials and structures. Incorporating imaging techniques such as lens-focused and near-field techniques, synthetic aperture focusing, holographical methods based on robust back-propagation algorithms with more advanced and unique millimeter wave imaging systems have brought upon a flurry of activities in this area and in particular for nondestructive evaluation (NDE) applications. These imaging systems and techniques have been successfully applied for a wide range of critical NDE-related applications. Although, near-field techniques have also been prominently used for these applications in the past, undesired issues related to changing standoff distance have resulted in several innovative and automatic standoff distance variation removal techniques. Ultimately, imaging techniques must produce high-resolution (in 3D) holographical images, become real-time, and be implemented using portable systems. To this end and to expedite the imaging process while providing a high-resolution images of a structure, recently the design and demonstration of a 6” by 6” one-shot, rapid and portable imaging system (Microwave Camera), consisting of 576 resonant slot elements, was completed. Subsequently, efforts have been expended to design and implement several different variations of this imaging system to accommodate one-sided and mono-static imaging, while enabling 3D image production using non-uniform rapid scanning of an object, as well as increasing the operating frequency into higher millimeter wave frequencies. This presentation provides an overview of these techniques, along with illustration of several typical examples where these imaging techniques have effectively provided viable solutions to many critical NDE problems. Speaker Biography R. Zoughi received his B.S.E.E, M.S.E.E, and Ph.D. degrees in electrical engineering (radar remote sensing, radar systems, and microwaves) from the University of Kansas where from 1981 until 1987 he was at the Radar Systems and Remote Sensing Laboratory (RSL). Subsequently, in 1987 he joined the Department of Electrical and Computer Engineering at Colorado State University (CSU), where he established the Applied Microwave Nondestructive Testing Laboratory (amntl). He held the position of Business Challenge Endowed Professor of Electrical and Computer Engineering from 1995 to 1997 while at CSU. In 2001 he joined the Department of Electrical and Computer Engineering at Missouri University of Science and Technology (S&T), formerly University of Missouri-Rolla (UMR), as the Schlumberger Distinguished Professor. His current areas of research include developing new nondestructive techniques for microwave and millimeter wave testing and evaluation of materials (NDT&E), developing new electromagnetic probes and sensors to measure characteristic properties of material at microwave frequencies, developing embedded modulated scattering techniques for NDT&E purposes and real-time high resolution imaging system d
