In conjunction with NATIONAL ENGINEERS WEEK, The Future City Competition was held for the South Florida Region on January 17th 2015.The Future City Competition was conducted for the Middle Grade Students with the assistance of an Educator,Mentor to design a future city  and then build three-dimensional table top model to scale .The theme was “Feeding Future Cities”. The challenge: Select one vegetable and one protein and design a way to grow enough of each within your city limits to feed your citizens.

Many number of schools Participated in the event and Judging of the Models was done from 7.00 AM -2.00 PM with multiple number of Judges who were divided among teams and judged the Models.The winner was the St. Agnes Academy (in Key Biscayne) .

The Regional winners advance to the Future City Competition National Finals in Washington, DC from February 15–18, 2015.

Optical measurements of thin films by ellipsometry using numerical methods

Invited Lecture by

Frank Urban, Ph.D.
Associate Professor, FIU

Date: December 9, 2014
Time: 2:00 PM– 3:00 PM
Address: Department of Electrical and Computer Engineering Department, Florida International University, 10555 W. Flagler Street, Miami, Florida 33174
Room: EC-1105

Abstract: A major challenge for those utilizing ellipsometry is numerical processing of the measured data. Our recent work shows how the transcendental, multivalued equations arising from the physics of reflection from layers can be solved in the n-k plane. This approach applies the mathematics of Complex Analysis to solve the equations numerically. The work presented extends the n-k method to obtain solutions within the accuracy limit of each measurement. The system treated here is that of a thin absorbing film (Chromium) overlying a known substrate (Silicon). Solutions for a three-layer model of the Chromium film including film-substrate and film-air interfacial layers result in a mean square error (MSE) on the order of 0.01, a significant improvement over a single-layer mod-el. Relaxing the constraint of vertical homogeneity provides a six-layer model with the same interfacial layers and four sublayers of Chromium. The chromium layers have near-identical values of optical properties and an MSE of essentially zero (10-13). It is anticipated that additional methods will be needed for other classes of problems.

Short Bio: Professor Urban has been at FIU since Fall 1990. His interests are in nanoparticle thin films and optical measurements of thin films by ellipsometry using numerical methods. He has been active in the American Vacuum Society in the Thin Film and Surface Engineering Divisions.

Wireless Communication Protocols for Smart Grid Neighborhood Area Networks and Their Privacy Threats

Invited Lecture by

Kemal Akkaya, Ph.D.
Associate Professor, FIU

Date: December 2, 2014
Time: 2:00 PM– 3:00 PM
Address: Department of Electrical and Computer Engineering Department, Florida International University, 10555 W. Flagler Street, Miami, Florida 33174
Room: EC-1105

akkayaAbstract: The upcoming Smart Grid is envisioned to use communication networks for two-way flow of data that will be generated from several new applications. These applications will run on different components of Smart Grid communication network includ-ing Neighborhood Area Networks, Home Area Network and Wide Area Networks. For each of these network components, various underlying infrastructure alternatives and standards based on wireless, fiber, powerlines, etc. are being considered for development. In this presentation, I will first talk about the wireless networking infrastructure options for the implementation of Neighborhood Area Networks. Particularly, I will look at the possibility of applying IEEE 802.11s and Zigbee mesh standards. In the second part of the presentation, I will look at privacy concerns due to smart meter data collected through the Neighborhood Area Networks. The collection of near real-time household energy consumption may reveal a lot of information about the life and behavior within the home. Therefore, in addition to traditional security problems, researchers need to tackle the pri-vacy issues raised as a result of the implementation of the Smart Grid Advanced Meter-ing Infrastructure (AMI). I will describe two approaches to provide consumer privacy on AMI: The first approach relies on generating obfuscation values to hide the actual usage from eavesdroppers and utility companies while preserving the utility companies’ ability to use the data for state estimation. The second ap-proach is the ultimate solution that relies on fully homomorphic encryption systems. I will talk about the feasibility of using these two approaches on an IEEE 802.11s-based AMI network.

The Energy Systems Research Laboratory presents

Electric traction machine choices for

hybrid & electric vehicles

Invited Lecture by

James R. Hendershot

Date: Nov 20, 2014
Time:  2:00 PM– 3:00 PM
Address Department of Electrical and Computer Engineering Department, Florida International University, 10555 W. Flagler Street, Miami, Florida 33174
Room: EC-2300

Abstract: How and why did the design engineers decide which electric machine type to develop for modern hybrid & electric vehicles? Similar machine types seem to be used in all hybrids. The all electric vehicles have been developed using a different machine topology. This presentation reviews theToyota Prius hybrid vehicle and many that followed to gain insight to this question. We will explain vehicle traction motor design and selection. The audience will come away with clear understanding of the choices, some tradeoffs and a starting placein mind for their own efforts. Details will be presented for the drive train of nearly every such vehicle currently in production. Knowledge of what has been done earlier will help avoid re-invention.

 

Short Bio: James R. Hendershot is the CEO of Motor Solver, LLC – the designer & supplier of teaching Dyno-Kits to domestic and foreign universities for the ONR/NSF sponsored Curriculum Courses called Reforming Electric Energy Systems Curriculum for Renewable/Storage, Smart Delivery and Efficient End User. Mr.Hendershot was tutored in the design, Development and testing of PM brushless motors and generators by Mr Gene Aha,(the original developer of PM brushless machines for the Apollo Space Program).He was one of the early developers of Switched Reluctance motors and generators. His Research interests include developing generators and alternators for wind-turbines, EV’s, and gas micro-turbines.

ABSTRACT:
Soft evidence sources (i.e., human-based evidence) play a critical role in social networks and similar settings, where subjective evi-dence (e.g., opinions) is the norm. Study of opinion dynamics in these scenarios requires agent models that can capture the types of uncertainties and nuances characteristic of soft evidence (e.g., subjectivity of human-generated evidence, confidence bounds associated with such evidence). Convergence analysis becomes an extremely difficult problem in such environments because of evidence updating strategies, delays in evidence updating, and dynamic link structure (the set of ‘neighbors’ of an agent is not static). To address the corresponding challenges, we employ a Dempster-Shafer (DS) belief theoretic agent model. The consensus protocol we employ is guaranteed to generate what we refer to as a rational consensus, a notion which justifies the use of the con-sensus state to estimate the ground truth (even when it is unknown or only partially known). Its DS theoretic basis easily adapts itself to situations where agent states are captured with probability mass functions (which can be viewed as a special case of DS theoretic models). We also explore how this consensus protocol can be used to capture notions from social judgment theory (e.g., global affinity and the nature of persuasion of agents) thus leading to the formation of consensus clusters.
