Speech Title: The Development of a Non-Thermal Food Processing System Utilizing Underwater Shockwaves


Abstract: In aging society, non-thermal food processing has been receiving much attention to provide nutritious and fresh foods for elderly person. In past studies, several attempts have already been undertaken to develop cost-effective non-thermal food processing systems. This paper presents the design of non-thermal food processing system utilizing an underwater shockwave. Unlike existing techniques such as cold plasma, high voltage arc discharge, etc., the non-thermal food processing utilizing an underwater shockwave is known as a cost-effective technique, because it can be realized by using a high voltage multiplier, a pressure vessel, a high-voltage switch and a big capacitor. However, this method suffers from slow processing speed and high stress to the big capacitor. To overcome these problems, we develop a novel multiple electrode pairs with movable metal wires. By utilizing multiple electrode pairs with movable metal wires, the voltage level for generating underwater shockwaves can be reduced. Furthermore, the target food can be crushed by only one electric discharge. In other words, the proposed technique can improve the capacitor stress and charging time. The experiments using a laboratory prototype demonstrated that the proposed system outperforms existing systems.



Prof. Akashi Shigeo
Tokyo University of Science, Tokyo, Japan
 

Shigeo Akashi was certified as a Ph.D. holder by Tokyo Institute of Technology in 1987 and he is now a professor at Tokyo University of Science. He was the chair professor at the Department of Information Sciences at this university from 2015 through 2016. He was also an visiting researcher at Rome II University in 1994 and was an associate professor at Southern Illinois University in 2000. As for the academic and educational activities, he has been a member of Experts Committee Leading Scientific Education for Japanese Senior High Schools authorized by Ministry of Education, Culture, Sports, Science and Technology attached to Japanese Government since 2016. He is interested in the interdisciplinary research area ranging from applied mathematics through information sciences. As for the research activity on applied mathematics, in 2003, he solved the analytic function version of Hilbert's 13th problem, which was known as an open problem derived from the 13th problems belonging to the 23 problems which was introduced by Professor David Hilbert in 1900 and would play important roles in directing mathematics in the future. Since his research work on Hilbert's 13th problem proved to be related to the theory of data compression, he was nominated as an invited speaker in Asian Mathematical Conference 2013, which is the second largest international conference on mathematics and was held in Korea in 2013. Moreover, he was a member of Scientific Committee for Asian Conference on Nonlinear Analysis and Optimization which was officially approved as a satellite international conference of International Congress of Mathematicians 2014. As for the research activity on information science, he has been being certified as Distinguished Cisco Certified Active Instructor Approved by Cisco Networking Academy since 2012, which is administrated by Cisco Systems. Moreover, he was awarded 2018 APSCIT Fellowship by Asia Pacific Society for Computing and Information Technology. His joint research work with RKC Instruments Co. Ltd., namely the largest company in all Japanese companies producing temperature-measuring instruments, which is named as "An algorithm for discriminating the inside of a closed curve from the outside" was accepted as Patent ID.4760768 by Japan Patent Office attached to the Ministry of Economy, Trade and Industry attached to Japanese Government in 2011.

Speech Title: How the Leakage of Private Information Can Be Brought about through the E-mail Spoofing


Abstract: It is not well known that a large amount of personal information has been intentionally leaked and wiretapped through the e-mail spoofing, because it is difficult for us to solve the problem asking what kinds of network structures the e-mail spoofing frequently occurs on. In the former part of this talk, we present an example which can become an answer to this problem. Exactly speaking, if we assume that there exist two network segments, which are geographically separated from each other and assigned 172.16.0.0/22 and 172.16.0.0/23 for their network addresses, respectively, then we see that leakage of private information can be brought about by abusing the e-mail spoofing on this network layer protocols. In the latter half of this talk, we discuss another analogous problem which has been derived from such the problem as stated above. Exactly speaking, we discuss the problem asking troublesome relations between two network segments, which are geographically separated from each other, in spite that they share 172.16.0.0/22 with each other.

Speech Title: Experimental and Numerical Study on Longitudinal Bow in Cold Roll Forming for AA5052 Material


Abstract: Roll forming is a plastic forming process in which sheets of different thickness is passed through a series of roll stand to get its desired shapes. Many types of materials can be deformed using roll forming such as steel, iron, copper, aluminum and titanium which can be used for the manufacturing of automobiles and aircrafts structures. Roll forming is a die less process, which is cost-effective and more flexible, especially for small-scale production. Due to the flexibility of this process, the formed product has some time shape defects, the most common of which is longitudinal bow. In this paper, combination of numerical simulation and experimentation of Aluminum Alloy 5052 for longitudinal bow reduction has been studied for U-shape sections by using UBECO PROFIL and LS-DYNA software. Supporting stand is used in the experiment for the study of longitudinal bow height, which is significantly reduced with the application of supporting stand.
