A Novel Method for Detecting APT Attacks by Using OODA Loop and Black Swan Theory
2018
Advanced Persistent Threat(APT) attacks are a major concern for the modern societal digital infrastructures due to their highly sophisticated nature. The purpose of these attacks varies from long period espionage in high level environment to causing maximal destruction for targeted cyber environment. Attackers are skilful and well funded by governments in many cases. Due to sophisticated methods it is highly important to study proper countermeasures to detect these attacks as early as possible. Current detection methods under-performs causing situations where an attack can continue months or even years in a targeted environment. We propose a novel method for analysing APT attacks through OO…
Comparative efficiency of green and conventional bonds pre- and during COVID-19: An asymmetric multifractal detrended fluctuation analysis
2021
Abstract Motivated by the lack of research on price efficiency dynamics of green bonds and the impact of the COVID-19 on the pricing of fixed-income securities, this study investigates the comparative efficiency of green and conventional bond markets pre- and during the COVID-19 pandemic applying asymmetric multifractal analysis. Specifically, the multifractal scaling behaviour is examined separately during upward and downward trends in bond markets using the asymmetric multifractal detrended fluctuation analysis (A-MF-DFA) approach. The empirical findings confirm the presence of asymmetric multifractality in the green and traditional bond markets. Not surprisingly, inefficiency in both bon…
India Re-loaded: Vikas Swarup’s Slumdog Millionaire as a Postcolonial Novel
2012
Once “the jewel in the crown” of the British Empire, India for some time ceased to be the focus of interest for the British writers. Largely due to the success of its film version, Vikas Swarup’s Slumdog Millionaire (Black Swan, London, 2005, originally called Q and A) again drew the attention of the Western world to the problems postcolonial India has to face: poverty, crime, sex abuse, exploitation of children, police brutality and many more. In this paper, however, we are not going to compare the two versions of the story, i.e. the novel and the film, but primarily concentrate on the textual commentaries in the context of postcolonial theory and literature. Of particular interest for us …
Fukushima, or the Black Swan of Nuclear Energy
2012
By its own merits, the great earthquake that hit Japan on 11 March 2011 would have qualified as one of the worse disasters of recent times. With a magnitude of 9.0 MW, it was the most powerful known earthquake ever to have hit Japan, and one of the most powerful in history. It released a surface energy 2 × 1017 Joule. Enough, if harnessed, to power a city the size of Los Angeles for an entire year.
