Instructors/Speakers Prof. Jie TAO College of Material Science & Technology Nanjing University of Aeronautics and Astronautics China Abstract Fiber metal laminates (FMLs) are composed of metal layers and fiber layers, which are stacked in an alternating sequence of an aluminum or titanium alloy sheet and glass or carbon fiber reinforced resin prepreg. As a novel lightweight hybrid material in the aviation industry, FMLs offer a unique combination of properties such as high specific static properties and excellent impact resistance, along with outstanding fracture and fatigue resistance; these materials have been successfully utilized in the upper fuselage skin structures of the Airbus 380 and the cargo floor of the Boeing 777. In this presentation, I will briefly overview the recent development ...

Instructors/Speakers Prof. Zhong CHEN School of Materials Engineering Nanyang Technological University Singapore Abstract Water-repellent coatings have a number of engineering applications, including easy-cleaning, anti-corrosion, and anti-icing. In this talk, I will begin with the materials science fundamentals on water repellence, and then explain how these fundamental principles are applied to the development of water-repellent and icephobic coatings. Specific examples will be given for coatings on composites and aluminum alloys, two important classes of industrial materials. Practically useful coatings have to meet manifold requirements including mechanical durability, low cost (non-reliance on expensive equipment and can be easily processed), scalability (large quantity for large area), and applicability to complex shapes, etc. These requirements can be taken into consideration at the coating formulation ... |

Instructors/Speakers Prof. Anton DZHAMAY Professor School of Mathematical Sciences College of Natural and Health Sciences University of Northern Colorado U.S.A. Abstract Many interesting examples of discrete integrable systems can be studied from the geometric point of view. In this talk we will consider two classes of examples of such system: autonomous (QRT maps) and non-autonomous (discrete Painlevé equations). We introduce some geometric tools to study such systems, such as the blowup procedure to construct algebraic surfaces on which the mappings are regularized, linearization of the mapping on the Picard lattice of the surface and, for discrete Painlevé equations, the decomposition of the Picard lattice into complementary pairs of the surface and symmetry sub-lattices and construction of a binational representation of ...

Instructors/Speakers Prof. Anton DZHAMAY Professor School of Mathematical Sciences College of Natural and Health Sciences University of Northern Colorado U.S.A. Abstract Over the last decade it became clear that the role of discrete Painlevé equations in applications has been steadily growing. Thus, the question of recognizing a certain non-autonomous recurrence as a discrete Painlevé equation and understanding its position in Sakai’s classification scheme, recognizing whether it is equivalent to some known (model) example, and especially finding an explicit change of coordinates transforming it to such example, becomes one of the central ones. Fortunately, Sakai’s geometric theory provides an almost algorithmic procedure of answering this question. In this work we illustrate this procedure by studying an example coming from the theory ... |

Instructors/Speakers Prof. Xin CHEN Special Research Fellow School of Mathematical Sciences Shanghai Jiao Tong University China Abstract In this paper, we consider the homogenization problem for a non-symmetric L´evy-type operator in a medium with a periodic structure. Under a proper scaling of this operator, we establish the limit behavior of the rescaled operator as the scaling parameter tends to zero. This talk is based on a joint work with Zhen-qing Chen, Takashi Kumagai and Jian Wang. Biography Prof. Chen received his PhD at Warwick University, and is now a special research fellow (equal to associate professor) at Shanghai Jiao Tong University. His main research fields are stochastic process and stochastic analysis. Prof. Chen has published nearly 20 papers in top ... |

Instructors/Speakers Prof. Jian WANG Professor College of Mathematics and Informatics Fujian Normal University China Abstract In this talk we review some recent works on couplings of SDEs with Levy noises. As applications, we consider the corresponding ergodic properties in term of the total variation and the $W_1$-distance. Biography Prof. Jian WANG received his PhD from Beijing Normal University, and is now a full professor at Fujian Normal University. His main research fields are stochastic process and stochastic analysis. Prof. Wang has published more than 80 papers in top journals such as Journal of European Mathematical Society, Memoir of American Mathematical Society, Communication in Mathematical Physics, Journal of Functional Analysis and so on. |

Instructors/Speakers Prof. Limin ZHANG Chair Professor of Geotechnical Engineering Director of Geotechnical Centrifuge Facility Associate Director of Great Smart Cities Institute Associate Head of Department of Civil and Environmental Engineering Hong Kong University of Science and Technology Hong Kong Abstract An extreme storm may trigger a large number of flood spots, landslides and debris flows in Hong Kong. The consequences can be catastrophic. To develop strategies to cope with geohazrads induced by extreme rainstorms, a good understanding of the generation and propagation of hazards during a storm is essential. HKUST is in the process of developing a “Digital Hong Kong” multi-hazard simulation platform to evaluate possible hazardous processes in critical rainstorms in the entire Hong Kong. The simulation framework is ... |
