Demo abstract: wind measurements for water quality studies in urban reservoirs

Water quality monitoring and prediction are critical for ensuring the sustainability of water resources which are essential for social security, especially for countries with limited land like Singapore. For example, the Singapore government identified water as a new growth sector and committed in 2006 to invest S$ 330 million over the following five years for water research and development [1]. To investigate the water quality evolution numerically, some key water quality parameters at several discrete locations in the reservoir (e.g., dissolved oxygen, chlorophyll, and temperature) and some environmental parameters (e.g., the wind distribution above water surface, air temperature and precipitation) are used as inputs to a three-dimensional hydrodynamics-ecological model, Estuary Lake and Coastal Ocean Model - Computational Aquatic Ecosystem Dynamics Model (ELCOM-CAEDYM) [2]. Based on the calculation in the model, we can obtain the distribution of water quality in the whole reservoir. We can also study the effect of different environmental parameters on the water quality evolution, and finally predict the water quality of the reservoir with a time step of 30 seconds. In this demo, we introduce our data collection system which enables water quality studies with real-time sensor data.

Australia-Malaysia security cooperation as a pivotal component for more stable bilateral relations

In the 1980s and 1990s, Australian-Malaysian relations reached a critical juncture due to a series of crises, such as the 1986 capital punishment of convicted drug smugglers Barlow and Chambers, and the 1993 "recalcitrant" jibe by Australian Prime Minister Paul Keating. Following the election of the Howard government in 1996, relations continued to be on a roller coaster with the Malaysian Prime Minister Mahathir Mohamad leading anti-Australia protests over the "Howard Doctrine," the Australian leadership of the 1999 intervention in East Timor, and the "Deputy Sheriff" controversy. Despite this, defense relations between the two remained strong. The success of this cooperation rests on shared political commitment to the security of the region. This article examines the impact that positive cooperation in "high politics" has had in mitigating the negative aspects of crises in "low politics." It argues that close bilateral defense relations have worked to prevent the emergence of further critical junctures in 2012 following the collapse of the Australian-Malaysian refugee swap deal and statements by Australian politicians about Malaysia's poor treatment of asylum seekers, and in 2013 over the overt support by many Australian politicians of the opposition, especially Anwar Ibrahim, during the Malaysian general elections.

The sixth oceanic conference on international studies: Transitions in the Asia pacific

The Sixth Oceanic Conference on International Studies (OCIS) was held in Melbourne, Australia between 9 and 11 July 2014. The conference was hosted by the School of Social and Political Sciences at University of Melbourne and supported by the Australian Institute of International Affairs, Deakin University, La Trobe University, Monash University, RMIT University and Swinburne University. The Sixth OCIS had a broad organizing theme of ‘transition’ focused on the changing balances of power shaping the Oceanic and Asia Pacific regions and related questions of social and political change in this context. Over 200 papers were presented at the conference, reflecting a wide variety of issues in international studies and related fields of scholarship. Amongst this diversity, the conference did have some recurring themes relating to great power rivalry, the influence of China, and the implications of multilateral frameworks and key bilateral relationships on the security and economic dynamics of the region. Significant attention was also devoted to analysing the foreign policies and political institutions for managing problems of peacebuilding, terrorism, gender inequality and sexual discrimination, people movements, climate change and financial instability at the regional and global levels. This special issue of Global Change, Peace and Security reflects these themes of transition in the Asia Pacific and comprises a diverse array of contributions from scholars attending this conference.

National security, surveillance and terror: Canada and Australia in comparative perspective

This edited collection brings together leading scholars to comparatively investigate national security, surveillance and terror in the early 21st century in two major western jurisdictions, Canada and Australia. Observing that much debate about these topics is dominated by US and UK perspectives, the volume provides penetrating analysis of national security and surveillance practices in two under-studied countries that reveals critical insights into current trends. Written by a wide range of experts in their respective fields, this book addresses a fascinating array of timely questions about the relationship among national security, privacy and terror in the two countries and beyond. Chapters include critical assessments of topics such as: National Security Intelligence Collection since 9/11, The Border as Checkpoint in an Age of Hemispheric Security and Surveillance, Unmanned Aerial Vehicles and Law Enforcement, as well as Federal Government Departments and Security Regimes. An engaging and empirically driven study, this collection will be of great interest to scholars of security and surveillance studies, policing, and comparative criminology.

Multi-agent approach for enhancing security of protection schemes in cyber-physical energy systems

This paper presents a distributed multi-agent scheme to detect and identify cyber threats on the protection systems of power grids. The integration of information and communication technologies (ICTs) into existing power grids builds critical cyberphysical energy systems CPESs) in which digital relays are networked cyber-physical components subject to various cyber threats. Cyber attacks on protection systems may mimic real faults, cause component failure, and disable the communication links. Agents utilize both cyber and physical properties to reinforce the detection technique and further distinguish cyber attacks from physical faults. This paper also introduces the problem of secure communicationprotocols and highlights the comparative studies for enhancing thesecurity of the protection systems. The proposed scheme is validatedusing a benchmark power system under various fault and cyber attack scenarios.
