SUMMARY:“ThirdEye: Visual Assist for Grocery Shopping”
DESCRIPTION:Title: “ThirdEye: Visual Assist for Grocery Shopping”\nSpeaker: Prof. Vijaykrishnan Narayanan\, Pennsylvania State University\, USA \nDate and Time: Wednesday\, November 15\, 2017 at 11:00AM-12:00PM \nLocation: 2430 Engineering Hall \nAbstract: \nShopping is widely considered as a relaxing leisure activity. However\, grocery shopping can be a frustrating experience for those with visual impairment. While getting to a grocery shop itself is not as much of a challenge for them\, locating and picking the items in the grocery shelf becomes a task as challenging as picking a needle from the haystack. Imagine picking up five items for your dinner recipe from a typical grocery store in the US that carries around 35\,000 unique items and can have more than 30 aisles spanning 45\,000 square meters. This talk will showcase synergistic advances in algorithms\, architectures and interface design for assisting those with visual impairment to do shopping. We will specifically focus on new non-boolean hardware approaches to significantly impact the energy-efficiency of the overall system. \nBiography: \nVijay Narayanan is a Distinguished Professor of Computer Science and Engineering and Electrical Engineering at The Pennsylvania State University. He is the director of the NSF Expeditions-in-Computing Program on Visual Cortex on Silicon and a thrust leader for the DARPA-MARCO LEAST Center. He has published more than 400 papers and won several awards in recognition of his research in power-aware systems\, embedded systems and computer architecture. He is a fellow of IEEE and ACM. \n

SUMMARY:"Network Resource Management in Cyber-Physical Systems"
DESCRIPTION:Title: “Network Resource Management in Cyber-Physical Systems”\nSpeaker: Dr. Xiabo Sharon Hu\, University of Notre Dame\, USA \nDate and Time: Friday\, November 17\, 2017 at 2:00PM-3:00PM \nLocation: ICS 432 \nAbstract: \nA cyber-physical system (CPS) is a system built from close integration of computational fabrics and physical components. Examples of such systems include avionic systems\, industrial control and civil infrastructure monitoring. In a CPS\, sensors and actuators are used to monitor and control the physical components while the computational fabrics determine the control values for the actuators based on the sensed data. All CPSs require timely delivery of sensed data from sensors to the computing fabrics and control signals from the computing fabrics to actuators. Managing the limited resources (e.g.\, computation power and communication bandwidth) to meet the timing requirements in a CPS is a challenging task. Even more challenging is that CPSs should degrade gracefully in the presence of various external disturbances such as failure in critical civil infrastructures and malicious attacks. \nIn this talk\, I first give a general introduction of WNCSs and the challenges that they present to network resource management. In particular\, I will discuss the complications due to external disturbances and the need for dynamic data-link layer scheduling. I then highlight our recent work that aims at tackling this challenge. Our work balances the scheduling effort between a gateway (or access points) and the rest of the nodes in a network. It paves the way towards decentralized network resource management in\norder to achieve scalability. Experimental implementation on a wireless test bed further validates the applicability of our proposed research. I will end the talk outlining our on-going effort in this exciting and growing area of research. \nXiaobo Sharon Hu is a professor in the department of Computer Science and Engineering at the University of Notre Dame\, Notre Dame\, Indiana\, USA.

SUMMARY:"I/O Optimization for Mobile Flash Storage"
DESCRIPTION:Title: “I/O Optimization for Mobile Flash Storage”\nSpeaker: Prof. Chun Jason Xue\, City University of Hong Kong \nDate and Time: Tuesday\, December 5\, 2017 at 10:00AM-11:00AM \nLocation: DBH 3011 \nAbstract: \nNAND flash memory is the primary choice of data storage for mobile devices due to its high performance\, shock resistance and low power consumption. However\, compared to high-end solid-state drives\, mobile flash storage does not have the luxury of sophisticated hardware and firmware features because of the resource-constraint limits. Instead\, mobile flash storage often equipped with scarce built-in RAM\, slow embedded processors and low-cost flash memories\, all of which make it a challenge to apply traditional techniques for I/O performance improvements. This talk presents a couple of work that we have done recently to optimize I/O for Mobile Flash Storage. First\, this talk will introduce a novel I/O scheduling approach to improve demand-based page-level mapping cache performance. This technique generates mapping cache friendly I/O workloads by strengthening I/O locality at host I/O scheduler. Both temporal locality and spatial localities are taken into consideration for I/O scheduling. Second\, this talk will present a lightweight data compression technique at the flash controller to reduce write pressure on mobile flash storage. It first characterizes data compressibility based on real smartphones\, and the analysis shows that write traffics bound to mobile storage volumes are highly compressible. This technique is the first to investigate firmware-based data compression for mobile flash storage without adding extra data compression hardware. Experimental results demonstrate the proposed techniques outperform state-of-the-art schemes in terms of I/O latency and flash memory lifespan. \nBiography: \nDr. Chun Jason Xue is an Associate Professor at City University of Hong Kong Computer Science Department. His research interests include non-volatile memories\, embedded and real time systems. He is currently Associate Editor for ACM Transaction on Embedded Computing Systems\, Associate Editor for ACM Transaction on CPS\, Associated Editor for ACM Transaction on Storage.
