Speaker: Dr. Sotiris Nousias, Postdoctoral Fellow | Department of Computer Science | University of Toronto
Talk Title: Computational Imaging with Photon Streams
Abstract: Among the yearly iterations on smartphone cameras and advances in sensor design, a key question emerges: what does the future's ultimate camera look like? In this presentation, I will explore the advanced capabilities of single-photon cameras, which have evolved from specialized scientific tools to being integral components in consumer devices like the iPhone. These cameras are not just sensitive; they are exceptionally precise, capable of detecting individual photons and their arrival times to the trillionth of a second. Traditionally, research in this field has focused on simple methods like counting or creating histograms of photons. My work, however, focuses on the raw 'photon stream' output – a sequence of photon arrival times that offers a rich, yet underexplored, source of data. By developing innovative mathematical models and algorithms, I open up exciting new possibilities, such as capturing high-speed videos at standard (30 Hz) and extremely high frame rates (>200 GHz), unveiling hidden 3D structures using multiply scattered light, and achieving micrometer-scale 3D imaging. I will discuss the remarkable capabilities of single-photon cameras and their potential to revolutionize various fields.

Talk Title: Transport Layer Innovations in Ultra-Low Latency Video Streaming
Abstract: In the post-pandemic era, ultra-low latency video streaming is increasingly popular nowadays. Numerous applications like videoconferencing, cloud gaming, virtual reality, remote driving are coming or have come to our daily life. However, these interactive video streaming applications require ultra-low and consistent latency to ensure the interactive experience, which challenges how the sender is transmitting packets and reacting to fluctuations nowadays.
My research rethinks the latency in interactive video streaming in an end-to-end way and tries to share some preliminary thoughts on what the network and related communities should do to enable the wide deployment of these applications. In this talk, I will present our work on how to achieve a consistent low latency for interactive video streaming. Specifically, I will talk about how we control the tail latency on the transport layer from the perspective of congestion control (Zhuge, SIGCOMM'22) and loss recovery (Hairpin, NSDI'24).
Biography: Zili Meng is an assistant professor at HKUST. He received his B.Eng. (Hons) and Ph.D. (Hons) from Tsinghua University. His current research interest focuses on ultra-low latency interactive streaming from all layers.

Talk Title: New Vistas in Autonomy Assurance
Series: EE598 Seminar Series
Abstract: Achieving trustworthiness is a major challenge preventing autonomous technologies from realizing their full potential in applications without an "undo" option for undesirable consequences. This talk argues that some obstacles to attaining assurance in autonomy result from applying traditional engineering and safety-critical system certification views and practices that are incompatible with the unique nature and potential use cases of modern autonomous systems. These systems are typically deployed in highly variable environments, which easily lead to violations of design assumptions. Additionally, autonomous systems consist of components that use hard-to-assure technologies, such as machine learning, and are also often built from components sourced from complex supply chains. This talk introduces assurance as an epistemic endeavor, emphasizing its value in designing and developing systems that are fit for purpose and use. We will then discuss the concept of agility and its role in reinterpreting the use and application of assurance cases for continuous assurance. This discussion will include the interpretation of context and operational domains. We will also describe a socio-technical solution, potentially enhanced by generative AI, to introduce assurance early in the system's lifecycle. Real-world examples from autonomous systems and applications studied at the Lockheed Martin Advanced Technology Laboratories will be used to illustrate these concepts throughout the presentation. Finally, we will highlight promising assurance technologies and identify gaps that require attention from the research community. By acknowledging these gaps, we hope to encourage further research and collaboration to address the challenges of assuring autonomous systems.

Talk Title: SUB-ATOMIC MOTIONS From capturing electrons to probing human health
Series: Munushian Visiting Seminar Series
Abstract: Born at the dawn of the new millennium, attosecond "photography" has opened the door for capturing sub-atomic motions as they evolve in time. Control of the oscillating electric field of light has permitted the attosecond control of electrons with unprecedented precision in space and time. Fundamental quantum phenomena, such as electron tunnelling and dipole oscillations in atoms or light-electron energy exchange in solids as well as fundamental classical phenomena, such as the field oscillations of visible light, became accessible to human observation in slow-motion replay. These capabilities open new avenues for 21st-century science, technology and medicine. Some of them emerge from the ability to sample light fields with attosecond precision. Possible implications of these advances include hundred thousand times faster electronics and cost-effective monitoring of human health.
Biography: Ferenc Krausz graduated in electrical engineering from the Budapest University of Technology and completed his studies in theoretical physics at the Eötvös Loránd University in 1985. He earned his doctorate in laser physics from the Technische Universität Wien (1991), where he became professor in 1998. In 2003-2004, he was appointed director at the Max-Planck-Institute of Quantum Optics in Garching and chair of experimental physics - laser physics at the Ludwig-Maximilians-Universität and established "Attoworld" at these two sites (attoworld.de).In a series of experiments performed between 2001 and 2004 his team succeeded in producing and measuring isolated attosecond pulses of light and applying them to observe sub-atomic motions. Attoworld has been fostering the proliferation of the emerging field, attosecond science, and - since 2015 - exploring its utility for probing human health. For his contributions to establishing the field of Attosecond Science, Ferenc Krausz has been awarded the King-Faisal International Prize for Science (2013), the Wolf-Prize in Physics (2022), the BBVA Frontiers of Knowledge Award (2023) and the 2023 Nobel Prize in Physics.

Talk Title: Continuous-Time Pipelined Analog-to-Digital Converters -“ Where Filtering Meets Analog-to-Digital Conversion
Series: Integrated Systems
Abstract: If someone told you that the power, noise, distortion, and area of a mixed-signal block could be reduced all at the same time, you'd probably think that this was a lie. It turns out that it is indeed possible sometimes - and this talk will present an example called the continuous-time pipeline (CTP) ADC. The CTP is an emerging technique that combines filtering with analog-to-digital conversion. Like a continuous-time delta-sigma modulator (CTDSM), a CTP has a "nice" input impedance that is easy to drive and has inherent anti-aliasing. However, unlike a CTDSM, a CTP does not require a high-speed feedback loop to be closed. As a result, it can achieve significantly higher bandwidth (like a Nyquist ADC). After discussing the operating principles behind the CTP, we describe the fundamental benefits of the CTP over a conventional signal chain that incorporates an anti-alias filter and a Nyquist-rate converter. We will then show design details and measurement results from a 100MHz 800MS/s CTP designed in a 65nm CMOS process.
