Instructors/Speakers Prof. Xiongbin PENG Assistant Professor Department of Mechatronics Engineering Shantou University China Abstract Large scale reflecting telescope is a technology-intensive equipment in many fields such as national security, space detection, universe exploration. They are usually equipped with large diameter primary mirrors, which guarantee them with stronger light gathering power and high resolution, to explore instant galaxies from hunderds of millions of light year away. In this context, this talk will firstly introduce the difficulties when designing a hydraulic support system for large scale primary mirrors. Secondly, the supporting stiffness of a hydraulic support system is analyzed. Thirdly, the methodology for the precise position control of a support system shall be discussed. Finally, the future directions with critical research areas ...

Instructors/Speakers Prof. Akhil GARG Associate Professor Department of Mechatronics Engineering Shantou University China Abstract In the recent years, Energy storage systems such as battery packs/fuel cells used in Electric vehicles (EVs) has been extensively promoted in developing economies where the environmental burden due to extensive production exists. In this context, this talk will firstly introduce the four main research problems undertaken. The development of evolutionary algorithms with applications in fuel cells is illustrated. Secondly, the experimental methodology of using mechanical parameter such as the stack stress to estimate the state of health of battery shall be discussed. The methodology for solving the design optimization problem of battery pack enclosure shall be discussed. Biography Dr. Akhil Garg is currently working as ...

Instructors/Speakers Prof. Anil Misra Professor Department of Civil, Environmental and Architectural Engineering The University of Kansas, Lawrence, Kansas, U.S.A. Abstract Granular materials take a variety of forms, spanning the spectrum from highly consolidated dense solids formed of particulate precursors to confined packing of non-cohesive particles. In all their forms, these materials are characterized by complex structures and compositions. More importantly, they share the common trait that their behavior at the macro-scale, that contains large numbers of grains (>106), is profoundly affected by the grain-scale interactions. For many important problems in engineering and science, continuum description of their mechanical behavior is desired. Discrete atomic or coarse-grained models often pose insurmountable challenges. Granular micromechanics method is a practical approach for continuum modeling ...
