Aerospace Engineering

Towards the Complete In-Canopy System for Autonomous Aerial Delivery


Wednesday, November 14, 2018; 4:30 PM - 5:30 PM
220 Hammond Building
Speaker: Mark Costello from Georgia Institute of Technology

Airdrop is a commonly used method of quickly deploying cargo and personnel to areas of interest.  It consists of releasing a payload at altitude in the vicinity of an intended landing area.  The payload is connected to an aerodynamic decelerator in the form of a parachute or parafoil to reduce the velocity in flight and at ground impact.  Compared to their unguided counterparts, current guided airdrop systems are relatively costly and have substantial logistics requirements, leading to limited use in practical environments.  For guided airdrop systems to be employed more frequently improvements in system cost, logistics footprint, and ease of use must be realized.  Toward this goal, new enabling technologies have been developed to improve landing performance while at the same time reducing the size, weight, power requirements, and cost associated with automatic control components by an order of magnitude.  This talk will discuss new guided airdrop system concepts that employ in-canopy bleed air actuation as the control mechanism, in-canopy sensing networks for feedback, and adaptive guidance, navigation, and control strategies.

Diffuse Optical Imaging of Breast Cancer Risk and Treatment Response


Thursday, November 15, 2018; 12:05 PM - 1:20 PM
158 Willard Building
Speaker: Dr. Thomas O'Sullivan from University of Notre Dame

Diffuse optical imaging (DOI) is a class of non-invasive near-infrared imaging techniques based upon measuring the wavelength-dependent absorption and scattering optical properties of living tissues. In the red to near-infrared optical therapeutic window, these optical properties provide information about deep (several cm) tissue composition, structure, and oxygen metabolism. In particular, DOI is capable of quantifying tissue concentrations of the physiologically relevant molecules oxyhemoglobin, deoxygenated hemoglobin, lipid, and water, as well as structural parameters including cellular size and density (obtained from scattering spectra). The significance and applicability of these and other DOI biomarkers collected with research devices have been demonstrated in numerous clinical studies of oncology, cardiovascular assessment, exercise physiology, and neuroscience. In this presentation, I will discuss how DOI has shown promise in the field of breast oncology for risk assessment, screening, differential diagnosis of benign and malignant lesions, and predicting and monitoring response to chemotherapy treatment. DOI biomarkers vary significantly in abundance and molecular state between breast cancer and normal tissue and unique cancer-specific absorption signatures have been observed. Finally, I will demonstrate how we are developing new technologies to accelerate the translation of this promising technology to clinical practice and my vision for the future.

Experimental Measurements of Laryngeal Airflow


Thursday, November 15, 2018; 9:00 AM
22 Deike Building
Speaker: Sid Khosla from University of Cincinnati Academic Health Center

Abstract: Two basic questions in laryngeal biomechanics are: 1) what is the source of sound during voice production and 2) what produces vocal fold (also known as vocal cord) vibration. Classic theory suggests the source of sound is due to flow modulation at the glottal (vocal fold). Latter aeroacoustic theories suggest that flow structures produce additional sources of sound.  Vocal fold vibration is due to a flow-structure interaction, but current theories differ in the exact details of this interaction. To validate and refine these theories, measurements in a tissue model are necessary. Until recently, such biological measurements were not technically possible. This talk will discuss experimental measurements of flow and vocal fold vibration in the excised animal larynx during voice production. The divergent-convergent shape of the vocal folds will be described. 2 D Particle Imaging Velocimetry of velocity fields between the vibrating folds will be shown, and the resulting pressure fields will be discussed. Tomographic PIV measurements of flow rate at the glottal exit will also be described. Differences between theory and experiments will be noted. Biography: Dr. Khosla is an Associate Professor in the Department of Otolaryngology-Head and Neck Surgery. For the past several years, he has done research with aerospace engineers on the underlying mechanisms of vocal fold vibration and sound production. This research has focused on applications in laryngeal reconstruction and in treating unilateral vocal fold paralysis. Principles of this research have been used, in addition to standard reconstruction techniques to improve the voices of patients who had severe laryngeal trauma. One example is the laryngeal reconstruction of a patient who had not talked for 35 years; her story and voice were featured in several national and international news stories. He is also a Member of the Cincinnati Opera Board and is strongly involved in clinical and research activities with the Cincinnati College Conservatory of Music. He has had a NIH K award and a current NIH RO1. He is an active member of the American Academy of Otolaryngology-Head and Neck Surgery and is board certified by the American Board of Otolaryngology-Head and Neck Surgery. He is also a Fellow of the American Laryngological Association. Dr. Khosla received his B.S. from the Massachusetts Institute of Technology, an M.S. in Biomechanics from the University of California, San Diego, and his M.D. degree from Bowman Gray School of Medicine in Winston-Salem, North Carolina. He completed his residency training in Otolaryngology and a Fellowship in Laryngology and Voice Disorders at Barnes-Jewish Hospital, Washington University School of Medicine in St. Louis.

Cancer Treatment: How Can We Do Better?


Monday, November 12, 2018; 4:00 pm
125 Reber Building
Speaker: Elsa Hansen from The Pennsylvania State University

Too often, our efforts to treat cancer fail. Recent mathematical, animal and clinical studies suggest that we can improve patient responses by using "containment" type strategies that leverage competition between drug-resistant and drug-sensitive cells. Successfully using these strategies requires identifying the sub-population of patients that will benefit from containment. I will present a framework that characterizes these patients and then apply this framework to an ongoing clinical study on prostate cancer. The framework suggests that current patient selection criteria (i) includes patients that are harmed by containment, (ii) reduces any potential benefit a patient may receive and (iii) fails to identify a class of patients that would actually benefit from containment. My intention is to initiate a discussion on how tools from dynamics, control and engineering could be leveraged to improve patient selection and treatment.

Additive Manufacturing of Metals: From Monolithic Structures to Functionally Graded Components


Tuesday, November 13, 2018; 3:35 pm
135 Reber Building
Speaker: Allison Beese from The Pennsylvania State University

Additive manufacturing (AM) of metals can be used to fabricate complex shaped components that cannot be manufactured using traditional methods.  However, the processing conditions during AM, consisting of rapid solidification and repeated thermal cycles, result in unique microstructures that differ from their wrought or annealed counterparts.  To adopt AM for load-bearing applications, an understanding of the links among processing, microstructure, and properties must be developed.  I will present our work on: (1) elucidating these links in monolithic components made by AM, and (2) designing and characterizing functionally graded materials made by AM in which the chemistry is varied with position, with the aim of spatially tailoring properties within a component.

Colloquium: Towards covert and secret quantum networks


Tuesday, November 13, 2018; 4:35 p.m.
358 Willard Building
Speaker: Prof. Matthieu Bloch from Georgia Tech

Abstract:  Despite steady progress in “post-quantum” cryptography, quantum-secured communication, especially in the form of Quantum Key Distribution (QKD), remains to date the only unconditionally secure technology to distribute secret keys. Quantum communication has effectively “leaped out of the lab” as most recently demonstrated in January 2018 with the deployment of a satellite-relayed intercontinental quantum network between China and Austria, leveraging the unique possibilities offered by the Micius quantum communication satellite. In this talk we will discuss the possibility of deploying quantum key distribution that are also covert, in the sense of being provable undetectable by an adversary. While covert key generation over quantum channels is not possible under the same assumptions than QKD, we will show that, perhaps surprisingly, covert secret key generation is possible under mild assumptions regarding the quantum channels. In particular, we will provide a more nuanced perspective regarding the impossibility of covert key expansion in covert quantum key distribution. We will also discuss the construction of reconciliation algorithms for covert secret key generation, where the main challenge is to efficiently process the diffuse information that is embedded in covert signals. We show that astute signaling and coding techniques enable one to "concentrate" the information and approach the information-theoretic performance with low-complexity.
