Redefining Human Security for Vulnerable Migrants in East Asia

This article proposes human security as an analytical framework to understand the current trends of irregular migration (both forced and unauthorised) in East Asia and revisits the seven pillars of human security defined in the 1994 Human Development Report by the United Nations Development Programme (UNDP). It explains how the concepts of human security are parallel to those prescribed in international human rights conventions but different in terms of the attitude towards states. Human security does not directly challenge state authority and adds a sense of urgency and moral authority that requires extra-legal measures by the states. The author argues that human security is the securitisation of human rights and is a better framework and policy discourse than human rights to engage with state and non-state actors, especially in East Asia where political leaders are more receptive to the former idea. The study draws examples from stateless Rohingyas, undocumented sex workers in Thailand and Singapore, trafficked brides from Vietnam and Cambodia, and smuggled North Korean refugees in China to demonstrate the nexus between human security and irregular migration

Concrete delamination depth estimation using a noncontact mems ultrasonic sensor array and an optimization approach

In this study, we present a method to estimate the depth of near-surface shallow delamination in concrete using a noncontact micro-electromechanical system (MEMS) ultrasonic sensor array and an optimization-based data processing approach. The proposed approach updates the bulk wave velocities of the tested concrete element by solving an optimization problem using reference ultrasonic scanning data collected from a full-depth concrete region. Subsequently, the depth of concrete delamination is estimated by solving a separate optimization problem. Numerical simulations and laboratory experiments were conducted to evaluate the performance of the proposed ultrasonic data processing approach. The results demonstrated that the depth of shallow delamination in concrete structures could be accurately estimated
