ai The Tangled Web is but a Fleeting Dream ... but then again... By www.ukoln.ac.uk Published On :: Wed, 23 Jul 2008 11:45:00 GMT James Currall will be giving a Plenary Talk on The Tangled Web is but a Fleeting Dream ... but then again... "Just a quick phone call to ask you if you could set up something to archive the University Web site, it should be pretty straight-forward for someone with your technical know-how." It is only a matter of time before someone in "Corporate Communications", the " Freedom of Information Office" or some similar department comes to you with this sort of request. How would you (have you) react(ed) to it? Many acres of virtual text have been penned on the subject of Web archiving (a fair proportion of them no longer available because the sites no longer exist:-) One of the major problems, which is well illustrated by the Wikipedia article on the subject, is that most authors have concentrated almost entirely on "How?" to do it and the (technical) difficulties that arise. The speaker will argue that "How?" is the least of your problems. What is your institutional web site for and what purpose is archiving it supposed to serve. To put it another way, the questions: "What?", "Why?", "When?" and "Where?" come well before deciding if the "Who?" is you, or trying to determine "How?". As usual Currall asks awkward questions and never seems to provide any useful answers, just turning seemingly simple problems in complex, issue-strewn minefields. He hasn't written the talk yet, but you can be sure that it will raise some very fundamental issues and give you something serious to think about and discuss and aside from manufacturing Shakespearean quotes, will probably quote from the most read book in the English Language, although you might feel the need to check that he isn't just making it up!

ai Online Adaptation for Safe Control of Constrained Dynamical Systems (November 14, 2024 3:00pm) By events.umich.edu Published On :: Wed, 06 Nov 2024 08:55:31 -0500 Event Begins: Thursday, November 14, 2024 3:00pm Location: Ford Robotics Building Organized By: Michigan Robotics Chair: Prof. Dimitra Panagou Abstract: Advances in sensing modalities and computational power have led to the prospect of a widespread deployment of robots in our society. Central to this objective is developing control and navigation stacks that avoid conservatism, presumed to be measured by a performance metric, while being provably and practically safe. A crucial element that must be accounted for is that controllers, which are typically designed for and tuned in laboratory or highly monitored industrial settings for a specific scenario, may experience a drop in performance and lose their safety guarantees when used elsewhere. It is of paramount importance therefore to import robots with the capability to adapt their controllers online to customize responses to a priori untested environments. In this dissertation, I present (1) tools to adapt any parametric controller using a model-based approach to achieve simultaneous satisfaction of multiple state constraints and enhanced performance; (2) a numerical scheme for predicting future state distributions in systems governed by stochastic dynamics with state-dependent disturbances, which can be utilized in model-predictive approaches; and (3) a method to assist decision-making on dropping (disregarding) constraints when it is not feasible to satisfy all constraints simultaneously. A significant part of the dissertation also focuses on a specific safety-critical control method - control barrier functions (CBF). The CBF-based controllers have garnered interest in recent years due to their ease of implementation. However, finding a theoretically valid CBF remains a challenge and in practice, they are prone to performance degradation and safety violations, especially when multiple CBFs are imposed together. This dissertation introduces a new notion of CBFs, called Rate-Tunable CBFs, that allows for time-varying parameters in theory and online tuning in practice. Full Article Presentation
ai CMENAS and Georgia State University Lecture Series. Bridging the Gulf: Patterns in Contemporary story from Kuwait to Oman (November 14, 2024 3:00pm) By events.umich.edu Published On :: Wed, 30 Oct 2024 20:17:37 -0400 Event Begins: Thursday, November 14, 2024 3:00pm Location: Off Campus Location Organized By: Center for Middle Eastern and North African Studies This presentation focuses on the importance of studying contemporary Gulf states. The definition of contemporary in this context considers the period starting from the early 1990s. The reason for this has to do with the collapse of the Soviet Union, regional changes like the invasion of Kuwait and its consequences, and the wider Middle Eastern regional consequences. The presentation also looks at the patterns that emerged in all Gulf states at the same time in different contexts: political, economic, and social. Mahjoob Zweiri is a professor of contemporary politics and Middle Eastern history with a focus on Iran and the Gulf region. He was the director of the Gulf Studies Center at Qatar University from 2018 to 2024 and the head of the humanities department from 2011 to 2016. Before joining Qatar University in 2010, Zweiri was a senior researcher in Middle Eastern politics and Iran at the Center for Strategic Studies, University of Jordan. From March 2003 to December 2006, he was a research fellow and then director of the Centre for Iranian Studies in the Institute for Middle Eastern and Islamic Studies at Durham University. Zweiri has more than 95 publications in the areas of Iran, contemporary Middle Eastern history and politics, Gulf studies, social sciences in universities of the future, and artificial intelligence’s role in social sciences. In addition to Arabic, he is fluent in Farsi and English. Zweiri is the founder and editor of the *Journal of Gulf Studies*, published by Intellect, and editor of the book series *Contemporary Gulf States*. Currently, he is a visiting professor at the University of Michigan. Register and attend over Zoom: https://myumi.ch/pkJWz. Full Article Lecture / Discussion
