Prof. Yuyuan Zhao, University of Liverpool, UK
Professor Yuyuan Zhao obtained his BEng and MSc degrees from Dalian University of Technology, and PhD degree from Oxford University. He worked as a Lecturer at Dalian University of Technology, a Research Associate at the MADYLAM Laboratory of CNRS, and a Research Fellow at Birmingham University, before he joined Liverpool University in 1998 as a Lecturer. He was subsequently promoted to Senior Lecturer, Reader and then Professor, and served as Head of the Centre for Materials and Structures from 2014 to 2016.
He is currently professor in materials engineering in the School of Engineering, the University of Liverpool. He is a Chartered Engineer (CEng) and a Fellow of the Institute of Materials, Minerals and Mining (FIMMM). Professor Zhao's current research is focused on the manufacture, characterisation and applications of porous metals and metal matrix syntactic foams.
He pioneered the Sintering and Dissolution Process (SDP) for manufacturing aluminium foam, which inspired the subsequent developments of several powder-based space-holder methods for manufacturing metal foams. He further invented the Lost Carbonate Sintering (LCS) process, a more versatile and cost-effective method for producing micro-porous metals. The LCS technology has led to the creation of Versarien, a highly successful start-up company which was floated on London Stock Market in 2013.
Professor Zhao was awarded the Ivor Jenkins Medal in 2015 by the Institute of Materials, Minerals and Mining for his contribution to powder metallurgy in developing and commercialising innovative powder based technologies for manufacturing metal foams.

Research interests of Prof. Hsu include Image Processing and Machine Vision, Metal Forming (Forging, Extrusion, Sheet-metal forming), Nano Imprint Lithography Applications, Molecular Dynamics Simulation. During his service at KUAS, Prof. Hsu has published 47 referred journal papers and has attended 26 international conferences among 13 countries to present his research results.
Speech Title: Automatic Optical Inspection and Measurement on Manufacturing
Image processing is processing of images using mathematical operations by using any form of signal processing for which the input is an image, a series of images, or a video, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the image. Image analysis can analyze image and to obtain its information and pattern matching uses correlation methods to help solve machine vision problems such as alignment, measurement, and inspection of objects. Image measurement can measure object in one or two or three dimensional ways. By integrating the above technologies and suitable lighting devices, central processing unit (computer) can help us to conduct automatic optical inspection and measurement.
This speech will give a brief introduction about image processing and machine vision. Then, several applications will be present, such as the inspection of dental floss picks, the inspection of bearing, the recognition and measurement of blot, nut and washer, the measurement of large scale spring with different pitch and different diameter, the measurement of sheet metal deformation in order to construct forming limit curve.

Speech Title: Microstructure and Mechanical Properties of Copper-Iron Fabricated by Mechanical Milling and Continuous Sintering
Abstract: This research is to analyze the effect of mechanical milling on the microstructure and mechanical properties of copper-iron. The sample is fabricated by compacting, milling and sintering processes. Sintering process is carried out using continuous type machine with conveyor belt mesh and the furnace type is muffle. After that, it is cooled with natural water jacket process. Vicker hardness testing and tensile strength test is performed to determine the mechanical properties of copper-iron alloys that occur. The mean value of sample 1 hardness (before milling) was 39.8 HV. The mean value of sample hardness 2 (after milling) was 74.9 HV. The value of the yield strength (σ) of sample 1 is 17.597MPa, and the value of ductility (ε) is 0.119. The value of the yield strength (σ) of sample 2 is 18.547 MPa, and the value of ductility (ε) is 0.073. The test results and analysis showed that by shrinking the size of metal powder, by milling for 2 hours, the hardness and yield strength of the product can increase. Although, the product becomes more brittle which is indicated by the decreased ductility value.
