Abstract:Recently, various simulation techniques have been developed. In addition, efficiency of analysis and model-based design have been also developed. On the other hand, the use of artificial intelligence technology is also remarkable. This paper is based on high-speed simulation technology. Furthermore, we will refer to the application to neural-based analog circuit synthesis technology.

Plenary II:Dec. 4, 20199:00 -- 10:00ROOM: Junior Manhattan
Abstract: Haze is one of the major environmental issues that have continuously vexed countries worldwide, including Malaysia, for the last three decades. During haze episodes, particulate matter ( PM10 ) is found as the major pollutant. Commonly, the severity of haze is determined by analysing quantitatively the concentration. Persistent homology is a tool used in topological data analysis to extract essential topological features from the data set. It is robust under perturbations of input data, independent of coordinates and dimensions alike, and offers a solid representation of qualitative features of the input data. This technique has been applied in various fields such as neuroscience, finance, medical, material science and many more. This talk aims to provide evidence of the efficacy of persistence homology on environmental data. In particular, we present our findings on the differences between the topological features of months with and those without haze episodes observed at air quality monitoring stations in Malaysia located in the areas of Jerantut, Klang, Petaling Jaya and Shah Alam. The haze episodes were characterized by summary statistics which reveal drastic changes in the lifetimes of the topological features from every station during haze episodes. We shall also talk about the cluster analysis of haze episodes and specifically focussing on the effectiveness of adding topological features in clustering techniques.
