On Detection of Network-Based Co-residence Verification Attacks in SDN-Driven Clouds

2017

Modern cloud environments allow users to consume computational and storage resources in the form of virtual machines. Even though machines running on the same cloud server are logically isolated from each other, a malicious customer can create various side channels to obtain sensitive information from co-located machines. In this study, we concentrate on timely detection of intentional co-residence attempts in cloud environments that utilize software-defined networking. SDN enables global visibility of the network state which allows the cloud provider to monitor and extract necessary information from each flow in every virtual network in online mode. We analyze the extracted statistics on d…

Decreases in aerobic fitness during military operations have been observed in several studies. Thus, differences in training adaptations during a 6-month crisis-management operation were compared by using the change in endurance performance as the outcome measure. Sixty-six male soldiers volunteered for the study, consisting of pre–post assessments of blood biomarkers, body composition, physical performance, and the military simulation test (MST) performance. Physical training volume was self-reported. After the follow-up, the data were divided based on individual changes in endurance performance. Endurance performance was improved in the high-responder group (HiR, n = 25) and maintained or…

Local expert experiences and perceptions of environmentally induced migration from Bangladesh to India

2017

This study investigates local expert perceptions of the role of environmental factors, especially in terms of contemporary climate change, in population movements from Bangladesh to India. The aim is to delve into locally held understandings of the phenomenon and to gain a better understanding of these migration processes, which are actively intertwined with local experiences. Both Indian and Bangladeshi experts were interviewed using semi-structured, in-depth interviews in order to explore insights from locally held perceptions and understandings of contextual factors. In total, 10 Bangladeshi and 15 Indian experts were interviewed, covering different disciplines, sectors, regions and job …

BDI Modelling and Simulation of Human Behaviours in Bushfires

2016

Each summer in Australia, bushfires burn many hectares of forest, causing deaths, injuries, and destruction of property. Emergency management strategies rely on expected citizens’ behaviour which differs from reality. In order to raise their awareness about the real population behaviour, we want to provide them with a realistic agent-based simulation. The philosophically-grounded BDI architecture provides a very suitable approach but is little used due to the lack of adapted tools. This paper uses this case study to illustrate two new tools to fill this gap: the Tactics Development Framework (TDF) and GAMA BDI architecture.

Kick Detection and Influx Size Estimation during Offshore Drilling Operations using Deep Learning

2019

An uncontrolled or unobserved influx or kick during drilling has the potential to induce a well blowout, one of the most harmful incidences during drilling both in regards to economic and environmental cost. Since kicks during drilling are serious risks, it is important to improve kick and loss detection performance and capabilities and to develop automatic flux detection methodology. There are clear patterns during a influx incident. However, due to complex processes and sparse instrumentation it is difficult to predict the behaviour of kicks or losses based on sensor data combined with physical models alone. Emerging technologies within Deep Learning are however quite adapt at picking up …

Towards a Bangsamoro in Mindanao?

2017

Mindanao was already settled by Muslims when the Spanish colonization began. Today, the western part of the island and the Sulu archipelago are territories with a majority Muslim population, whereas the rest of the Philippines is predominantly Christian. Since the sixteenth century, the “Moros” of Mindanao have fought outsiders, Spaniards first, then the Americans, and throughout history the other Filipinos. The settlement migration policy of the Philippine government in the middle of the twentieth century has transformed the human landscape of the central and eastern parts of Mindanao, now predominantly Christian, and created a major area of commercial plantations. Political opposition to …

Comprehensive defence in Latvia – rebranding state defence and call for society's involvement

2020

Abstract This article explores how comprehensive defence has been introduced in Latvia, and focuses on society's involvement and tasks in the state defence. This approach envisages a significant change in society's relationship with the armed forces and state defence. Differently from many other countries, Latvia maintains its system without introducing conscription and instead puts efforts towards youth education in defence. Additionally, the Ministry of Defence involves different society groups and NGOs in defining their role in state defence. This article also discusses the concepts of resistance and non-collaboration as part of comprehensive defence.

Introduction: Research Interest and Research Questions

2017

This chapter explores the theoretical and empirical puzzles of regionalism in the Global South on the example of the Southern African Development Community (SADC). The SADC is one of the most realistic and promising examples of the new regionalism and shows constant dynamics in a number of policy areas. The main research interest of this much-needed analysis is to explain the emergence, institutional design and performance of regionalism in the SADC from a political science perspective. In order to provide innovative research, the analytical focus is on the role and influence of regional key countries and, particularly, external actors. Moreover, this chapter offers a comprehensive overview…

Backlash against the procedural consensus

2020

While the politics of backlash is typically described as a reaction to policy decisions in favour of minority rights, immigration or globalisation, this essay focuses on the fact that backlash typically also involves a reaction against the procedural consensus liberal democracy is based upon. This challenge to democratic procedures and institutions may be even more dangerous in its effects than the substantial objectives of backlash. I use the composite definition of backlash suggested by Alter and Zürn to assess in how far the attacks on the institutions of liberal democracy have retrograde objectives in themselves or in how far they are merely instrumental to the pursuit of other retrogr…

The “Refugee Crisis,” Immigration Attitudes, and Euroscepticism

2019

Between 2015 and 2017, the European Union (EU) was confronted with a major crisis in its history, the so-called “European refugee crisis.” Since the multifaceted crisis has provoked many different responses, it is also likely to have influenced individuals’ assessments of immigrants and European integration. Using data from three waves of the European Social Survey (ESS) — the wave before the crisis in 2012, the wave at the beginning of the crisis in 2014, and the wave right after the (perceived) height of the crisis in 2016 — we test the degree to which the European refugee crisis increased Europeans’ anti-immigrant sentiment and Euroscepticism, as well as the influence of Europeans’ anti-…
