                    報告題目:Failure of Thermal Barrier Coatings under Isothermal Oxidation and Solid Particle Erosion

                    Turbine blades used in aerospace industry are operated at high temperatures for maximum efficiency and power output. Commonly used nickel-based superalloys for these components exhibit deficiency in such a high temperature condition, therefore thermal barrier coatings (TBCs) have been developed, which can be applied on the nickel-based superalloy substrate via various deposition techniques, to reduce the temperature exerted on the substrate material.

                    In this research, the failure behavior of a TBC system that consists of an 8 wt% yttria partially stabilized zirconia (YSZ) top coat and CoNiCrAlY bond coat, deposited on nickelbased superalloy Inconel 718 substrate via atmospheric plasma spraying (APS) process, has been studied experimentally under isothermal oxidation at 1050C, 1100°C, and 1150°C in air condition for different exposure durations up to approximately 2000 h.The solid particle erosion behavior of as-deposited and aged TBCs is investigated at room temperature.A temperature and exposure time-dependent interfacial fracture toughness model for TBCs has been proposed.

                    報告題目:Intellectual Property Creation - Research as a Business Venture

                    報告人:Jens Grabenstein (Carpmaels & Ransford)


                    報告地點:騰訊視頻會議ID:658 5662 4196



                    The presentation gives an overview of what patents are and how to obtain them. The second half of the talk will discuss some recent success stories of companies that were founded on the basis of intellectual property created at universities, with a particular focus on companies developing vaccines against Covid-19.


                    Jens Grabenstein is a Life Sciences patent attorney with 13 years of experience in non-contentious and contentious patent matters. He enjoy the intellectual challenge of accompanying research, regulatory and commercial teams in their endeavour to turn a scientific discovery into a medicine that improves people’s lives. His experience stretches from the initial invention harvesting and patent drafting to the defence of patents in both opposition proceedings and multi-jurisdictional patent litigation. His passion is to help companies build strong patent portfolios from the ground up, covering all stages from the initial discovery, to product development and manufacturing. He currently works as a Senior Associate in the Life Sciences practice group at Carpmaels & Ransford in London.

                    報告題目:High-Fidelity Mathematical Modelling, Fast-Time Simulation and  Artificial Intelligence Techniques for Flight Safety Protection in 9/11' Class Scenarios

                    報告人:Dr. Ivan Y. BURDUN


                    報告地點:騰訊視頻會議ID:658 5662 4196



                    9/11 class scenarios relate to abnormal flight situations characterized by inadequate, a priori catastrophe-prone aircraft control tactics (manual, automated, or automatic).

                    A knowledge-centered solution approach is presented for predicting and protecting aircraft flight safety under complex conditions with multiple or unknown risks - at and beyond operational constraints. The technique is based on the synergy of high-fidelity mathematical modeling of the pilot/automaton - aircraft - operating environment system dynamics, autonomous fast-time computer experimentation with the model  (M&S), artificial intelligence (AI), knowledge mining and mapping (M&M), and a 'bird's eye view' visual analytics. Its key concepts include: situation scenario, risk factor, multifactorial risk hypothesis, safety palette, fuzzy constraint, integral safety spectrum, situational tree, safety window, safety ‘topology’, ‘last chance for recovery’ point, etc.

                    A large set of off-nominal flight paths - what-if variations of the baseline situation's flight path - are automatically generated in advance in fast-time AI-driven M&S experiments. For this purpose, AI 'silicon pilot' model and tree growth control algorithms are used to explore combined effects of related risk (and/or remedial) factors. Situational trees can accumulate extra-large synthetic flying experience - the system's 'alternative futures' built around baseline scenarios.

                    The technique's advantages are summarized,   however,there are many unsettled issues and prerequisites to be addressed in further studies
