Abstract This talk will provide an overview of two major Inverter Based Resource (IBR) events occurring on May 9th, 2021 and June 4th, 2022, originating in West Texas, informally known as the “Odessa Events”. These events resulted in the tripping of numerous inverter based generators in West Texas on the ERCOT system. The scope of this discussion will include: - Details concerning the origin and impact of each event - Causes of each solar PV reduction on the ERCOT system - Explanation of each inverter fault code - Corrective actions determined by discussions between ERCOT and inverter Original Equipment Manufacturer (OEM) - Summary of ERCOT activities in response to Odessa Events Speaker(s): Julia Hariharan, Agenda: Mixer/Food-Refreshments/Sign-In: 6:00 PM to 6:30 PM Program: 6:30 PM to 7:45 PM Networking: 7:45 PM to 8:00 PM Bldg: Building R, Lupe Tortilla, 10515 N MoPac Expy, Austin, Texas, United States, 78759, Virtual: https://events.vtools.ieee.org/m/351509

Thanks to electronic enabling technologies, machine learning (ML) has gained momentum to get a pervasive paradigm in many applications due to the unquestionable results achieved. Yet, ML appears as a misused buzzword for attracting scientific interest and curiosity. The main problem of ML is the vastity of the tools and techniques mostly linked to neural network architec-tures. In this presentation, I will show how a niche of ML, based on statistical inference, could achieve highly reliable predictive models on reduced da-tasets. Instead of increasing the architectures to follow the algorithmic com-plexity, I will show a reverse approach, where the simplicity of the predictive models could be embedded in simple, low-power architectures. The main ad-vantages of these techniques are first to avoid complex elaborations, being suitable for edge computing, and secondly to develop tools on a robust mathe-matical background, such as multivariate analysis helping the developers to a critical understanding of the raw data. I will show results on different appli-cations based on spectral sensing information processing in precision agricul-ture and structural engineering and how this approach could be extended to any kind of spectral sensing (microwave, mm-wave, terahertz radiation, ultra-sound, optical, infra-red, mass spectroscopy).

IEEE 802.11be, which is also known as Wi-Fi 7, is the next amendment to the IEEE 802.11 standard for wireless local area networks (WLAN). This amendment is anticipated to greatly enhance the performance of indoor and outdoor WLAN operations at both stationary and pedestrian speeds in the 2.4, 5, and 6 GHz frequency bands. Wi-Fi 7, also called Extremely High Throughput (EHT), is set to provide multi-gigabit Wi-Fi with faster speeds, less interference, and better performance for high-bandwidth online activities. The new standard is expected to achieve a theoretical maximum speed of 30 Gbit/s, which is a significant improvement from the previous standard, IEEE 802.11ax. In this talk, Laurent Cariou will deliver a high-level overview of the features that are defined in the upcoming standard. Additionally, he will briefly introduce the next activity in 802.11, known as Ultra High Reliability (UHR), which is expected to become Wi-Fi 8. Biography Laurent Cariou earned his Ph.D. in electronics from the National Institute of Applied Sciences in Rennes, France in 2003 and 2006, respectively. He has spent over a decade working in IEEE 802.11 and currently serves as Intel's principal engineer and technical lead for mainstream Wi-Fi in 802.11. Cariou played a key role in establishing the High-Efficiency WLAN (HEW) group that eventually led to the development of 802.11ax and Wi-Fi 6. Recently, he also initiated the Extremely High Throughput (EHT) activity. Currently, Cariou holds the position of vice-chair for the 11be/EHT task group (Wi-Fi 7) and is also the chair for the Ultra-High Reliability (UHR – Wi-Fi 8) study group.

Design of analog CMOS circuits requires, obviously, a proper understanding of how MOS transistors work. Almost all design textbooks present incorrect small-signal models for MOS transistors. They emphasize Cgd, which is (for the intrinsic transistor) negligible in saturation, and completely ignore Cdg, which is the 2nd largest capacitance in saturation (where most MOS transistors in analog circuits operate). What is the difference between Cgd and Cdg? Why is the most important of these in saturation not Miller multiplied? Why are the gm and VDsat values that SPICE tells you wrong? Find out in this talk!

Most decisions have two requirements: They should be “good”, and secondly when others are involved, they should be agreed to. The normative decision model provides a decision tree with 8 critical factors that determine, not what a decision should be, but how the decision should be made. This talk use a common, relevant scenario – whether or not to require a team to terminate remote work and return to the office – to walk through the model. The talk will end with a discussion on how the model generalizes and provides alternatives for anyone faced with the challenge of making a good decision. Speaker(s): Karl Arunski, Agenda: 6:00 to 6:10 PM - Open for participants to enter and network. 6:10 to 6:15 PM - IEEE LM and CTCN Business meeting and to introduce speaker. 6:16 to 7:30 PM - Formal Program and Q&A.

In-Person Location: Ingram School of Engineering, San Marcos University, Room IGRM 4104 Virtual: Zoom (https://txstate.zoom.us/j/91084259333) Date: April 21, 2023 Time: 11:00 am – 1:00 pm Talk Title: “Efficient and Scalable Deep Learning Based Object Recognition Methods” Speaker: Mr. Vittal Siddaiah, Senior Engineering Lead, Intel F&B is included for in-person format Cost: none Abstract: Artificial Intelligence (AI) is the panacea for prescriptive and predictive analytics through Machine Learning (ML) techniques, demands for computational performance, and snowballing over the decades. Pattern Recognition is increasingly demanding in AI applications that include neural networks-based machine learning. In this research, we are dealing face recognition domain of pattern recognition and person detection, popularly classified under computer vision. Training deep-learning models are compute-intensive, and there is an industry-wide trend toward hardware specialization to improve performance. This research uses a DNN-based generic, efficient, scalable, and platform-independent framework that can be extendable across platforms. The proposed framework involves computer vision techniques suitable for unsupervised learning with low latency and high performance. The proposed framework is validated across diverse datasets, compatible and scalable across platforms, has low latency, and has a small footprint. The framework would serve as a benchmark and publish the rating parameters of response times, latencies, and accuracy that grade and differentiates various platforms. Bio: Vittal is a senior engineering lead at Intel with 19 years of experience architecting several silicon validation tools. He has led several designs of a validation tool suite for pre- and post-silicon validation. He is distinguished for his contributions to the machine learning-based, high-performance design of tools. Some of his innovations include defining metrics and measurements of power and performance. He has earned several recognitions and awards, including “One Generation Ahead Award” and “Waste Elimination Award.” Vittal has developed multiple teams, mentored leaders, and is passionate about mentoring engineers and students. He has won the “Best Trainer Award” at Intel. Some domains include Hardware-software co-design, Operations Research, Image Processing, Operating systems, System Design and Optimization, and High-Performance Computing. Vittal is an avid learner with his Masters in Electrical Engineering, Masters in Management, M Phil in Management, and Masters in Mathematics.

Abstract Abstract: - Investigation of a widespread vacuum switch interrupter component failure experienced on 138-kV vertical air break switch. Failure analysis was conducted with a joint effort of LCRA and the Field testing conducted by LCRA demonstrated 50% loss of the component at 20 operations. Similar results were observed from a HV laboratory test conducted by Turner Electric. IEEE std 1247-2005 section 8.3.1.8 test duty may not be adequate for what utilities need. LCRA mitigated the failure risk through maintenance practice revision, procedure update, and heavy-duty hardware implementation. - Investigation of inoperable 3WAY GOAB Transmission Switch concerns and LCRA’s new design solution overcoming the challenges. While the popular 3 WAY GOAB Transmission Switches design offered by all major manufacturers may have a flaw that raises switch availability concerns and inoperable problems.
