Quantum Tricks In The Shadows Of Relativity And The Coulomb Force: Teaching Devices And Students How To Think Ultra-Fast, Ilias Perakis

Physics Seminars

The technological demand to bump the Gigahertz switching speed limit of today's magnetic memory and logic devices into the Terahertz regime underlies the entire field of spin-electronics and integrated multi-functional nano-devices. In this talk, I use theory and experiment to show how all-optical switching based on the quantum-mechanical manipulation of spins with a train of laser pulses could meet this challenge. The creation of magnetic correlations within femtoseconds, i.e. faster than one period of lattice oscillations, reveals a new temporal regime of magnetism. This field opened new directions for manipulating materials out-of-equilibrium using Terahertz, Mid-infrared, and X-ray pulses.

Similarly soft magnetic materials figure prominently in applications in electric vehicles and high torque motors. Dramatic weight and size reductions are possible in such applications by hold potential for applications in active magnetocaloric cooling of such devices. Bulk and thin film soft magnet sensors can contribute to the search for oil and critical materials. Opportunities for state of the art soft magnetic to impact such applications have been furthered by investment by USDOD …

Predicting Parkinson's Disease Progression With Smartphone Data, Pramod Anantharam, Krishnaprasad Thirunarayan, Vahid Taslimi, Amit P. Sheth

Kno.e.sis Publications

Most of the existing approaches for detecting diseases/risk score form observations (sensor and textual) ignore the presence of any prior knowledge of the disease. In this work, we start top-down by enumerating the symptoms of Parkinson's Disease (PD) and map the symptoms to its possible manifestations in sensor observations (bottom-up). We show such manifestations and further use these manifestations as features to build classifiers to differentiate between the PD patients and the control group.

High-Performance Thermal Management, Kirk Yerkes

Physics Seminars

Traditionally thermal management systems are designed for steady-state behavior. Air Force systems tend to be highly complex, coupled, and highly-dynamic. The concept of high-performance thermal management offers a paradigm shift in the technical approach to thermal management to one that addresses the inherent need to develop thermal management systems. This seminar will address the conceptual and philosophical approach to addressing the science and engineering needed to evolve thermal management technologies for high-performance and rapidly responding thermal management systems.

Enhancing Ir Sensor Coupling Using Surface Plasmon Resonances, John S. Cetnar

Physics Seminars

The mid-infrared (mid-IR) region of the electromagnetic spectrum is defined from λ ~ 8 – 14 μm. There are many important applications for mid-IR sensing including military, scientific, medical, and commercial. Unfortunately, the performance of current mid-IR detectors is limited by low optical absorption. Surface plasmons (SPs) can be used to enhance the coupling between mid-IR radiation and mid-IR detectors. There are many structures that can generate SPs in the mid-IR region. Two particular structures, the grating coupler and the Sierpinski carpet, seem particularly interesting. The grating coupler is of interest because of its good performance and simplicity of fabrication. …

What Kind Of #Conversation Is Twitter? Mining #Psycholinguistic Cues For Emergency Coordination, Hemant Purohit, Andrew Hampton, Valerie L. Shalin, Amit P. Sheth, John M. Flach, Shreyansh Bhatt

Kno.e.sis Publications

The information overload created by social media messages in emergency situations challenges response organizations to find targeted content and users. We aim to select useful messages by detecting the presence of conversation as an indicator of coordinated citizen action. Using simple linguistic indicators associated with conversation analysis in social science, we model the presence of conversation in the communication landscape of Twitter in a large corpus of 1.5M tweets for various disaster and non-disaster events spanning different periods, lengths of time and varied social significance. Within Replies, Retweets and tweets that mention other Twitter users, we found that domain-independent, linguistic …

From Solute Transport To Chemical Weathering, Allen Hunt, Thomas E. Skinner

Physics Seminars

A theory for conservative solute transport, based on concepts from percolation theory, is applied directly to reactive solute transport. Chemical reactions are assumed to have reached equilibrium at the scale of an individual pore, but at larger length scales, equilibration is limited by solute transport velocities, which are not the same as fluid velocities! The results of this theory already predicted observed dispersivity values for conservative solute transport over ten orders of magnitude of length scale as well as the variation of solute arrival time distributions with medium saturation. We now show that the solute velocity predicts the time-dependence of …

Following a cognitive engineering approach, users were involved at each step of the design. An intermediate study allowed refining the information processing in order to better fit the actual need. On the basis of interviews and activity analysis, functionalities were implemented aiming at improving anticipation skills. In the context of a flight simulator and …

Issues Relevant For Synthetic Teammate – Human Teammate Interactions In Operations Of A Synthetic Unmanned Aerial System, Nancy J. Cooke, Christopher W. Myers

International Symposium on Aviation Psychology - 2013

Two experiments are reported that set the stage for a project in which an ACT-R based Air Vehicle Operator will interact with two human teammates in an Unmanned Aerial System synthetic environment. Of interest are the ways in which the synthetic teammate fails to coordinate in an effective manner with humans. In Experiment 1, the new communication mode of text chat is compared to voice communications used previously in this task environment with all human participants. Issues of team performance and coordination were examined and differences noted particularly due to lag in the asynchronous chat mode. In Experiment 2 a …

Examining Memory For Search Using A Simulated Aerial Search And Rescue Task, Brandon S. Perelman, Shane T. Mueller

International Symposium on Aviation Psychology - 2013

In this paper, we report on the development of a synthetic task environment (STE) representing wilderness search and rescue using unmanned aerial vehicles (UAVs) for investigating human unmanned aerial search behavior. Participants navigated using a north up topographical map and detected targets using a more detailed track up satellite image representing the view through the UAV’s camera. Participants then completed (1) a path reconstruction task and (2) a memory test in which they indicated locations where they found targets. These tasks aim to address two information types that map onto distinct visual processing pathways afferent to the hippocampus. We discuss …

Experimental Effective Intensity Of Steady And Flashing Light Emitting Diodes For Aircraft Anti-Collision Lighting, Chris Yakopcic, John Puttmann, Benjamin R. Kunz ., Clara Ang, Ashley Mcpherson, David Santez, Matt Donovan, John Skarzynski, Joshua Trick, Andrew Mead ., Nelda Milburn ., Nazih E. Khaouly

International Symposium on Aviation Psychology - 2013

Research was conducted to determine the effective intensity of flashing lights that incorporate light-emitting diodes (LEDs). LEDs require less power and have the ability to flash without the addition of moving parts. Compared with incandescent bulbs, however, LEDs yield a different spectral output and a different intensity profile when flashing. To determine the effect of these differences on a viewer’s ability to detect the light, we examined LEDs to determine if they can successfully replace legacy technologies/assemblies on aircraft. The LED was displayed to naïve subjects to establish visibility thresholds using an automated system to drive the LED with variable …

An Investigation Of Thermal Imaging To Detect Physiological Indicators Of Stress In Humans, Carl Brady Cross

Browse all Theses and Dissertations

Real-time, stand-off sensing of humans to detect emotional state would be valuable in many defense, security and medical scenarios. Using a multimodal sensor platform that incorporates high-resolution visible-wavelength and mid-wave infrared cameras and a millimeter-wave (mmW) radar system, the detection of physiological indicators of psychological stress is tested through laboratory experiments. Our approach focuses on thermal imaging to measure temperature patterns in distinct facial regions representative of underlying hemodynamic patterns. Experiments were designed to: 1) determine the ability of thermal imaging to detect high levels of psychological stress and assess responses to physical versus psychological stressors; 2) evaluate the fidelity …

Abiotic Reduction Of Nitrite And Nitrate By Nanoscale Chemogenic Magnetite: Pathways For Significant Greenhouse Gas Production, Adam Charles Burdsall

Browse all Theses and Dissertations

The biogeochemical cycling of nitrogen in terrestrial systems is a major source of nitrous oxide (N₂O), which is among key greenhouse gases (GHG). While biotic processes are commonly accepted as the major drivers of N₂O production, the role of abiotic processes is less understood, and their importance may be underestimated. This study investigates abiotic reactions in the formation and breakdown of N trace gases, including nitric oxide (NO) and nitrous oxide (N₂O) by naturally occurring nanoscale magnetite in soil as denitrification (reduction of nitrite) intermediates. Nitrogen biogeochemical cycling has been studied extensively with respect …

The Warehouse-Inventory-Transportation Problem For Multi-Echelon Supply Chains, Bhanuteja Sainathuni

Browse all Theses and Dissertations

Warehouses play a vital role in mitigating variations in supply and demand, and providing value-added services in a supply chain. However, our observation of supply chain practice reveals that warehousing decisions are not included when developing a distribution plan for the supply chain. This lack of integration has resulted in substantial variation in workload (42%-220%) at our industry partner's warehouse costing them millions of dollars. We address this real-world challenge by investigating the interdependencies between warehouse, inventory, and transportation decisions, integrate them in a mathematical programming model, and develop managerial insights based on solutions of industry-sized problem instances. Our three …

Measuring Human Factors Success In Acquisitions, Jason Demagalski, Dr Branka Subotić, Dr Jerry Crutchfield, Dr Dwayne Norris

International Symposium on Aviation Psychology - 2013

Human factors specialists work as part of multidisciplinary teams supporting acquisition programs. Depending upon the acquisition model and culture of an organization, the exact points of involvement of human factors specialists may vary, as too will the metrics of success for each project. Acceptable/optimal level of operational performance is the goal of any Air Traffic Control (ATC) system. Human performance is a key component of operational performance. Measuring human performance can be an area of academic debate often yielding vague answers or need for more research. This is of little use or interest to project and senior managers who make …

A Resolution Procedure For Description Logics With Nominal Schemas, Cong Wang, Pascal Hitzler

Computer Science and Engineering Faculty Publications

We present a polynomial resolution-based decision procedure for the recently introduced description logic ELHOV_n(⊓), which features nominal schemas as new language construct. Our algorithm is based on ordered resolution and positive superposition, together with a lifting lemma. In contrast to previous work on resolution for description logics, we have to overcome the fact that ELHOV_n(⊓) does not allow for a normalization resulting in clauses of globally limited size.
