CPSRC Seminar Series: Precision Measurement of Mild Brain Trauma Using an Instrumented Mouthguard
Abstract:
Mild traumatic brain injury (mTBI) affects 45 million people worldwide each year and can lead to neurodegenerative tauopathys such as Alzheimer’s and Chronic Traumatic Encephalopathy. My goal is to enable early detection and prevention of mTBI. My laboratory has pioneered instrumented mouthguard technologies that precisely measure the acceleration of the head during impact, which we use to drive finite element (FE) models of the brain and calculate injury location and severity. In this talk, I will describe the instrumented mouthguard technology development and validation, as well as initial clinical results of FE computed brain strain compared to novel highly sensitive neuroimaging data. This preliminary data suggests that blood brain barrier disruption, a potential initiator of neurodegeneration, may be very common in contact sports and is detectable in real-time with the mouthguard. Finally, I will present data on early prototypes of an optimal shock absorber that has the potential to prevent mTBI in helmets for football and other high-risk activities.

CPSRC 2018-19 Academic Year Kick-Off Event
Start out the 2018-19 academic year at the Cyber-Physical Systems Research Center (CPSRC) kick-off gathering, Thursday, September 27th, from 1:30 to 3:30 pm in room E2-599. The agenda includes a summary of the center's recent accomplishments, projects and activities, as well as a snapshot of the great opportunities ahead for this year. Refreshments will be served, plus there will be plenty of time to network and discuss with your colleagues and our industry affiliates who have also been invited. The event is open to current CPSRS affiliates and any current or new students, postdocs or faculty interested in becoming affiliates or just learning more -- so invite anyone you think might be interested. We hope to see you there.
CPSRC Seminar Series: On Boundary Feedback Control of 1-D Hyperbolic Conservation Laws: Robustness to Measurement Noise
Abstract:
The tight description of many physical phenomena relies on mathematical models in which variables that depend simultaneously on space and time are related each other through differential relationships. This leads to systems modeled via partial differential equations (PDEs). Systems modeled via PDEs are omnipresent in physical sciences and this has a dramatic impact on the relevance of PDE models in engineering applications.
In this talk, we will consider a special class of hyperbolic PDEs, i.e., the class of 1-D linear hyperbolic conservation laws. The main interest in linear hyperbolic conservation laws is that such equations are ubiquitous in physical applications. Transport of electrical energy, the flow of fluids in open channels, the motion of chemicals in flow reactors; just to mention some, are typical examples of processes that can be mathematically described by 1-D linear conservation laws.
The main focus of this talk is on boundary feedback control design for 1-D linear hyperbolic conservation laws. Sufficient conditions in the form of Lyapunov-like functional inequalities are given to certify the existence of a bound on the $\mathcal{L}_2$ (spatial) norm of the state with respect to energy bounded measurement noise. Semidefinite programming techniques are adopted to devise a systematic design algorithm. The effectiveness of the approach is shown in a numerical example.

CPSRC Seminar Series: Making aerial robotics safer in the face of external disturbances
Abstract:
Flying robots, such as multicopters, are increasingly becoming part of our everyday lives, with current and future applications including personal transportation, delivery services, entertainment, and aerial sensing. These systems are expected to be safe and to have a high degree of autonomy. This talk will discuss the dynamics and control of multicopters, with a focus on making these vehicles more robust to external disturbances, and component failures. Finally, we will present the application of a failsafe algorithm to a fleet of drones performing as part of a live theater performance on New York’s Broadway.

CPSRC Seminar Series: Real-time Analytics and Scale-out Machine Learning with FPGA Key-Value Store
Abstract:
Key Value Store (KVS) provides a highly scalable means to store and retrieve distributed data over a network. In datacenters, high performance KVS allow large numbers of machines to share data by reading and writing key/value pairs over high-speed Ethernet. Algo-Logic has implemented a scaled-up KVS using Field Programmable Gate Array (FPGA) logic that achieved record-setting low latency, high throughput, and low power consumption. In this talk, it will be shown how this FPGA KVS was scaled out to accelerate machine learning for self-driving cars using a Markov Decision Process (MDP). Parallel systems were put together with the FPGA KVS to scale up machine learning and perform real-time decision making for 30 self-driving cars in a simulated highway driving environment.
