Abstract:
Thermally-assisted magnetic recording (TAMR) and microwave-assisted magnetic recording (MAMR) are the two candidates for achieving an areal density of multi-terabit per square inch (Tbit/in2 firsthalf, magnetic write heads are modeled and analyzed micromagnetically for TMAR combined with shingled recording, targeting an areal density of 8 Tbit/in2 more than 8 Tbit/in2 system. In the second half, a model analysis was used to investigate a spin-transfer torque oscillator (STO) and magnetic write head for shingled MAMR, where the interactions between STO and write head were included. The magnetic head had a tilted main pole (MP) – trailing shield (TS) gap with respect to the medium surface. The head structure gives a larger recording field gradient in the crosstrack direction due to the wide pole. A STO placed in a tilted MP–TS gap had stable oscillation at cost of a small reduction in oscillation amplitude. is possible with shingled recording, compared with 4.4 Tbit/in2

A Magnetic “Spin” on Cancer Treatment

by Sakhrat Khizroev

Professor of Electrical and Computer Engineering, College of Engineering and Computing, FIU
Professor of Cellular Biology and Pharmacology Herbert Wertheim College of Medicine, FIU


Date: May 15, 2014
Time: 11:00 AM – 12:00 Noon
Place:  EC-2300, Engineering Center at 10555 West Flagler Street, Miami

Abstract:
Cancer is a complex disease of genetic alternations and cellular abnormalities that result in uncontrolled growth and progression of tumors. Despite advances in molecular biology research, the overall survival rate from cancer has not significantly improved. The current mostly chemistry-based approaches are limited because of the lack of adequate specificity of treatment to eradicate cancer while spare healthy cells. Although the circulatory system in conjunction with biomarker- specific monoclonal antibodies and/or receptor-driven ligands can deliver a drug to every cell in the body, bringing a drug inside the tumor cell past its membrane without affecting the healthy cells remains a formidable task. Needless to say, the emergence of a high-specificity targeted delivery technology would be a significant breakthrough. To overcome this stumbling block, we proposed a new “smart” nanotechnology approach that exploits the physics of magnetic spin to enable a molecular-level control of drug targeting and delivery. The approach takes advantage of (i) the difference between the membrane electric properties of cancer and healthy cells and (ii) the capability of magneto-electric nanoparticles (MENs) to serve as converters of a remotely supplied magnetic field into the nanoparticles’ intrinsic electric fields that in turn can trigger local nano-electroporation effects. This capability allows to remotely control the electric fields in the vicinity of intravenously injected drug-loaded nanoparticles and consequently enable the required specificity of the drug delivery to the tumor cells. Such fundamental control at the molecular level also opens a new pathway to develop a universal approach to “program” passive and active “tagging” properties of drug-loaded nanoparticles by tailoring them to specific biomarkers and receptors and ideally capable of “catching” isolated cancer stem cells.

Game Theory for Networked Systems: A Tutorial

by Dr. Walid Saad,

Professor, Ph.D., University of Miami

Date: Friday, May 2, 2014
Time: 11:00 AM – 12:00 PM
Place:  FIU Engineering Center, EC 3960
10555 W. Flagler Street, Miami, Florida

Abstract:
Next-generation networked systems, such as wireless networks or the smart grid, are characterized by three key features: heterogeneity, in terms of technology and services, dynamics, in terms of rapidly varying environments and uncertainty,and size, in terms of number of users, nodes, and services. The need for smart, distributed and self-organizing networking designs designs has become a central research issue in a variety of applications and scenarios. Incorporating self-organizing capabilities in heterogeneous networked systems motivates the development of innovative analytical techniques. In this respect, game theory is expected to play a critical role towards deploying intelligent, distributed, and flexible networked systems in which network devices can make independent and rational strategic decisions, smartly adapting to their environment.
This tutorial provides a comprehensive introduction to noncooperative game theory, reinforcement learning,
and cooperative game theory as they apply to the design of future networks. For each type of games, we present the fundamental components, introduce the key properties, mathematical techniques, and solution concept, and we describe the challenges and methods for applying these games in several emerging fields such as wireless networks, smart grid, and cybersecurity.

Distributed Control and Plug-n-Play Operation of Distribution Networks and Microgrids

by Dr. Zhihua Qu,

Professor and Chair of ECE, University of Central Florida, Orlando

Date: Friday, March 28, 2014
Time: 10:00 AM – 11:00 PM
Place:  FIU Engineering Center, EC 1115
10555 W. Flagler Street, Miami, Florida

Abstract:
In a smart grid, unpredictable and distributed generation must be seamlessly and autonomously incorporated into the operation of distribution networks and microgrids. In this talk, a plug-n-play design is presented for the general class of cyber-physical cooperative systems which consist of individual heterogeneous nonlinear physical systems, a physical network, and a network of intermittent local communication channels. By introducing a simple impact coefficient to quantify interactions among heterogeneous physical systems, a fully modular design methodology is proposed to separately design individual feedback controls of physical systems and network-level cooperative control, and their combination enables plug-n-play operation of the overall networked physically-constrained systems. For distribution networks and microgrids, the proposed control design renders distributed cooperative control/optimization algorithms that enable distributed VAR compensation, loss minimization and optimal dispatch of aggregate active power from distributed generation units. Sample results will be presented to illustrate their effectiveness.

The Development and Future of Antenna Arrays

by Randy L. Haupt

Professor and Chair, Colorado School of Mines

Date: Friday, Jan 24, 2014
Time: 10:00 AM – 11:00 PM
Place:  Room no.1115,ECE Department, FIU
10555 W. Flagler Street, Miami, Florida

Abstract:

Large antennas create the high gain needed to boost the received signal for a communications or radar system. Today, reflectors and arrays compete for large aperture jobs in many types of systems. In general, the reflector is relatively inexpensive, that is why it is the antenna of choice for commercial activities, such as satellite TV. If the reflector must be moved in order to locate or track a signal, then the gimbals, servomotors, and other mechanical parts become a reliability and maintenance issue that becomes a significant lifecycle cost. Also, mechanical steering might be too slow to meet some of the demands on platforms such as airplanes. The array – in particular, the phased array – makes many performance promises but for a price.

Some of the unique features of a phased array antenna include:

  1. Fast, wide angle scanning without moving the antenna.
  2. Adaptive beamforming
  3. Graceful degradation in performance over time
  4. Distributed aperture
  5. Multiple beams
  6. Potential for low radar cross section

This paper presents the historical development of array antennas. Reflectors have a rich history in optics that started thousands of years ago. Arrays, on the other hand, are only a little more than 100 years old, while phased arrays are only a little more than 70 years old. This presentation introduces the antenna array concept and provides a historical development of the array from the very beginning until the present with a peak into the future. Many examples and pictures will be presented.

Breaking Barriers in Controlling the Mind

by Dr. Sakhrat Khizroev

Professor and Director, Center for Personalized Nanomedicine

Florida International University

Date: Thursday, Dec 19, 2013
Time: 12:00 PM – 1:00 PM
Place:  Room no. EC-3753, FIU
10555 W. Flagler Street, Miami, Florida

Abstract:

In February 2013, President Obama announced the plan to start the Brain Activity Map (BAM) Project, a 15-year initiative aimed at charting the entire circuitry of the human brain. Today, there is no practical way to directly map the electric field in response to the neural activity; nor is there a way to remotely stimulate the neural activity deep in the brain. A few years ago, we proposed to use energy-efficient magneto-electric nanoparticles (MENs) to bridge remote magnetic fields with the intrinsic electric fields deep in the brain and thus enable both electric-field mapping and remotely-controlled stimulation. Like the conventional magnetic nanoparticles (MNs), used as magnetic resonance imaging (MRI) contrast agents, the MENs have a non-zero magnetic moment and therefore their spatial distribution can be controlled remotely via an external magnetic field gradient. In addition, unlike the conventional MNs, MENs display an entirely new property, which is the non-zero magneto-electric (ME) effect. This ME coupling can be used to enable remote stimulation of selective regions in the brain as well as sensing the local electric field induced by the neural activity in the brain. To use MENs for electric-field mapping, the new nanoparticles must be used together with an existing magnetic imaging technique such as MRI or the recently emerged magnetic nanoparticle imaging (MNI). In this case, MENs modulate the typical structural image obtained by MRI with the local electric field. Moreover, when used with MNI, MENs can be used for field mapping in real time (with a temporal resolution in the microsecond range). The potential applications span from the prevention and treatment of neurological disorders to opening a pathway to the fundamental understanding of the brain which potentially could lead to reverse-engineering the brain. Further, MNI in conjunction with MENs is suitable for real-time studies of the neural activity field dynamics deep in the brain to understand less known intrinsic processes. This talk will summarize the current findings of our in-vitro and in-vivo studies.

Wide-Area Control of Power Systems using Synchrophasors:
Theory, Design and Experiments

by Aranya Chakrabortty, PhD

Assistant Professor of Electrical Engineering

FREEDM Systems Center, NC State University

Date: Friday, Nov 22, 2013
Time: 10:00 AM – 11:00 PM
Place:  Room no.1107,ECE Department, FIU
10555 W. Flagler Street, Miami, Florida

Abstract:

A key element in the development of smart power transmission systems over the past decade is the tremendous advancement of the Wide-Area Measurement System (WAMS) technology, also commonly referred to as the Synchrophasor technology. Significant research efforts have been made on techniques to use WAMS for monitoring and situational awareness of large power networks dispersed across wide geographical areas. In contrast, use of WAMS for automatic feedback control has received less attention from the research community. The objective of this talk is to bridge this gap by formulating wide-area control problems for oscillation damping and voltage control. We will pose four distinct control-theoretic problems. The first problem will be on using PMU measurements from selected nodes in a power system to identify reliable dynamic models with related discussions on identifiability and PMU placement. The remaining three problems will be to employ these models for designing output feedback damping controllers via control inversion, model predictive control, and energy function based methods. Some initial results on how these control mechanisms may be implemented in a distributed way on top of any typical arbitrated communication network with inherent time-delays will also be presented. Results will be illustrated using examples from the US west coast grid (WECC), as well as real-time simulations from the BEN-WAMS testbed recently developed at NC State.
