Dual-image-based reversible data hiding scheme with integrity verification using exploiting modification direction

Abstract(#br)In this paper, a novel dual-image-based reversible data hiding scheme using exploiting modification direction (EMD) is proposed. This scheme embeds two 5-base secret digits into each pixel pair of the cover image simultaneously according to the EMD matrix to generate two stego-pixel pairs. By shifting these stego-pixel pairs to the appropriate locations in some cases, two meaningful shadows are produced. The secret data can be extracted accurately, and the cover image can be reconstructed completely in the data extraction and the image reconstruction procedure, respectively. Experimental results show that our scheme outperforms the comparative methods in terms of image quality and embedding ratio. Pixel-value differencing (PVD) histogram analysis reveals that our scheme..

Multispace & Multistructure. Neutrosophic Transdisciplinarity (100 Collected Papers of Sciences), Vol. IV

The fourth volume, in my book series of “Collected Papers”, includes 100 published and unpublished articles, notes, (preliminary) drafts containing just ideas to be further investigated, scientific souvenirs, scientific blogs, project proposals, small experiments, solved and unsolved problems and conjectures, updated or alternative versions of previous papers, short or long humanistic essays, letters to the editors - all collected in the previous three decades (1980-2010) – but most of them are from the last decade (2000-2010), some of them being lost and found, yet others are extended, diversified, improved versions. This is an eclectic tome of 800 pages with papers in various fields of sciences, alphabetically listed, such as: astronomy, biology, calculus, chemistry, computer programming codification, economics and business and politics, education and administration, game theory, geometry, graph theory, information fusion, neutrosophic logic and set, non-Euclidean geometry, number theory, paradoxes, philosophy of science, psychology, quantum physics, scientific research methods, and statistics. It was my preoccupation and collaboration as author, co-author, translator, or cotranslator, and editor with many scientists from around the world for long time. Many topics from this book are incipient and need to be expanded in future explorations

Data, Debt & Daemons: Systemic Asymmetries on Spaceship Earth

Day by day, the rate at which we create new data increases exponentially. Our capacity to learn cannot keep up. We are tiny members of a vast universal network, incapable of discerning cause and effect. Instead, we develop simplified narratives, leaving ourselves misguided yet complacent. The information management trade of both physical and intellectual property has become more vital to global economies than ever, replacing physical resources and manufacturing. Through our deepening reliance on specialization, we forfeit agency over our own homes while accruing unprecedented debt. Housing costs have risen dramatically compared to wages, despite reportedly successful economies. Citizens were supposed to have the ability to participate in financial markets using their property as collateral. This seduced many into the ideologies of unregulated capitalism. However, by the 21st century, these systems had become unrecognizable mutilations of their intended designs. The momentum we have gathered in the past century has thrust us on an unsustainable trajectory we have little hope of predicting. We laid the foundation for Western economic dominance with technology, monetary policy, and globalization, but we did so using incentive structures that exacerbated wealth inequality. These systems integrate digital technology into both our physical and virtual spaces, operating on invisible planes that bypass our senses. The radical novelty of computers has entangled us in niche engineered concepts that few understand. They create a lack of accountability in Big Tech that policy-makers are ill-prepared for. We cannot ensure an equitable distribution of the leverage or stakes when we entrust brokers, politicians, traders, and captains of industry to make complex decisions for us without bearing the risks of their consequences. Our long-term welfare, including our future habitation on this planet, is not visceral enough to force effective reform. Both our physical and our digital spaces are designed, built, evaluated, and monitored on asymmetric principles, causing disasters that future generations and the least fortunate always pay for. How did we normalize this moral hazard? How can digital systems born out of frustration with modern policy combat these issues, without disrupting the benefits of a techno-utopia? How can they promote efficiency, security, and transparency in the spaces we call home

The zone of "becoming": game, text and technicity in videogame narratives

Videogames have emerged as arguably the most prominent form of entertainment in recent years. Their versatility has made them key contributory factors in social, literary, cultural and philosophical discourse; however, critics also tend to see videogames as posing a threat to established cultural parameters. This thesis argues that videogames are firmly grounded in older media and they are important for the development of the notions of textuality, technicity and identity that literary and cultural theories have been debating in recent years. As its point of departure, the thesis takes the contested role of videogames as storytelling media. Challenging the opposition between games and narratives that is posited in earlier research, the framework of the Derridean concept of supplementarity has been adopted to illustrate how the ludic and the narrative inform each other's core, and yet retain their media-specific identities. It is also vital to consider how the technicity and narrative of games inform their perception as texts. Videogames provide a direct illustration of this but they develop on similar principles in earlier media instead of doing something entirely 'new'. The multitelic structure of videogames tends to be looked upon as symptomatic of novelty; in reality, however, they illustrate more clearly the inherent nature of telos in all narrative media

Keys to Play: Music as a Ludic Medium from Apollo to Nintendo

How do keyboards make music playable? Drawing on theories of media, systems, and cultural techniques, Keys to Play spans Greek myth and contemporary Japanese digital games to chart a genealogy of musical play and its animation via improvisation, performance, and recreation. As a paradigmatic digital interface, the keyboard forms a field of play on which the book’s diverse objects of inquiry—from clavichords to PCs and eighteenth-century musical dice games to the latest rhythm-action titles—enter into analogical relations. Remapping the keyboard’s topography by way of Mozart and Super Mario, who head an expansive cast of historical and virtual actors, Keys to Play invites readers to unlock ludic dimensions of music that are at once old and new

Metaphor, metonymy, language learning and translation

This thesis investigates the role of metonymy in communication, in creating text, in learner communication and in translation. I make the claim that metonymy, defined here as the ability to recognize part-whole relations between things, words and concepts, is the essential mechanism behind a whole variety of linguistic phenomena, normally dealt with in linguistics as distinct topics. In the General Theory of Metonymy presented here, I suggest that metonymy is a unifying principle behind how we process language. I discuss a range of data to demonstrate metonymy at work. I show that metonymic principles are not just in play in metonymic language but also in metaphoric and literal language. I argue that metonymy not only offers alternative ways of referring to entities, but is powerful in giving nuance and spin, and is the key to understanding why language is so fit for purpose in giving us the flexibility and subtlety so important in our social dealings with others. I illustrate the role metonymy plays in our lives by examining data from social and recreational activities where metonymy is central and seems to be explored for its own sake. In the Metonymic Theory of Learner Communication I propose that learner communication relies in a number of different ways on metonymic processing; and in the Metonymic Theory of Translation I propose that translation also relies heavily on metonymic processing. The burgeoning interest in metonymy in recent years has generated an extensive literature. This thesis attempts to make sense of this body of knowledge, offers an original synthesis of it, proposes how it might be developed and suggests practical applications of it. I suggest that a new discipline of Metonymics might emerge and that this could make a valuable contribution in reframing issues of debate in a variety of different areas of practice
