Data protection based neural cryptography and deoxyribonucleic acid

The need to a robust and effective methods for secure data transferring makes the more credible. Two disciplines for data encryption presented in this paper: machine learning and deoxyribonucleic acid (DNA) to achieve the above goal and following common goals: prevent unauthorized access and eavesdropper. They used as powerful tool in cryptography. This paper grounded first on a two modified Hebbian neural network (MHNN) as a machine learning tool for message encryption in an unsupervised method. These two modified Hebbian neural nets classified as a: learning neural net (LNN) for generating optimal key ciphering and ciphering neural net CNN) for coding the plaintext using the LNN keys. The second granulation using DNA nucleated to increase data confusion and compression. Exploiting the DNA computing operations to upgrade data transmission security over the open nets. The results approved that the method is effective in protect the transferring data in a secure manner in less tim

Entropy in Image Analysis II

Image analysis is a fundamental task for any application where extracting information from images is required. The analysis requires highly sophisticated numerical and analytical methods, particularly for those applications in medicine, security, and other fields where the results of the processing consist of data of vital importance. This fact is evident from all the articles composing the Special Issue "Entropy in Image Analysis II", in which the authors used widely tested methods to verify their results. In the process of reading the present volume, the reader will appreciate the richness of their methods and applications, in particular for medical imaging and image security, and a remarkable cross-fertilization among the proposed research areas

Dynamical Systems

Complex systems are pervasive in many areas of science integrated in our daily lives. Examples include financial markets, highway transportation networks, telecommunication networks, world and country economies, social networks, immunological systems, living organisms, computational systems and electrical and mechanical structures. Complex systems are often composed of a large number of interconnected and interacting entities, exhibiting much richer global scale dynamics than the properties and behavior of individual entities. Complex systems are studied in many areas of natural sciences, social sciences, engineering and mathematical sciences. This special issue therefore intends to contribute towards the dissemination of the multifaceted concepts in accepted use by the scientific community. We hope readers enjoy this pertinent selection of papers which represents relevant examples of the state of the art in present day research. [...

The symposium aimed to publish high-quality papers strictly related to the various theories and practical applications concerning advanced smart applications, future ICT, and related communications and networks. It was expected that the symposium and its publications would be a trigger for further related research and technology improvements in this field

Three Risky Decades: A Time for Econophysics?

Our Special Issue we publish at a turning point, which we have not dealt with since World War II. The interconnected long-term global shocks such as the coronavirus pandemic, the war in Ukraine, and catastrophic climate change have imposed significant humanitary, socio-economic, political, and environmental restrictions on the globalization process and all aspects of economic and social life including the existence of individual people. The planet is trapped—the current situation seems to be the prelude to an apocalypse whose long-term effects we will have for decades. Therefore, it urgently requires a concept of the planet's survival to be built—only on this basis can the conditions for its development be created. The Special Issue gives evidence of the state of econophysics before the current situation. Therefore, it can provide excellent econophysics or an inter-and cross-disciplinary starting point of a rational approach to a new era

Stochastic timeseries analysis in electric power systems and paleo-climate data

In this thesis a data science study of elementary stochastic processes is laid, aided with the development of two numerical software programmes, applied to power-grid frequency studies and Dansgaard--Oeschger events in paleo-climate data. Power-grid frequency is a key measure in power grid studies. It comprises the balance of power in a power grid at any instance. In this thesis an elementary Markovian Langevin-like stochastic process is employed, extending from existent literature, to show the basic elements of power-grid frequency dynamics can be modelled in such manner. Through a data science study of power-grid frequency data, it is shown that fluctuations scale in an inverse square-root relation with their size, alike any other stochastic process, confirming previous theoretical results. A simple Ornstein--Uhlenbeck is offered as a surrogate model for power-grid frequency dynamics, with a versatile input of driving deterministic functions, showing not surprisingly that driven stochastic processes with Gaussian noise do not necessarily show a Gaussian distribution. A study of the correlations between recordings of power-grid frequency in the same power-grid system reveals they are correlated, but a theoretical understanding is yet to be developed. A super-diffusive relaxation of amplitude synchronisation is shown to exist in space in coupled power-grid systems, whereas a linear relation is evidenced for the emergence of phase synchronisation. Two Python software packages are designed, offering the possibility to extract conditional moments for Markovian stochastic processes of any dimension, with a particular application for Markovian jump-diffusion processes for one-dimensional timeseries. Lastly, a study of Dansgaard--Oeschger events in recordings of paleoclimate data under the purview of bivariate Markovian jump-diffusion processes is proposed, augmented by a semi-theoretical study of bivariate stochastic processes, offering an explanation for the discontinuous transitions in these events and showing the existence of deterministic couplings between the recordings of the dust concentration and a proxy for the atmospheric temperature

Water Stress and Early Childhood Development in Palestine: Making the Link, and Implications for Policy and Practice

Introduction: The percentage of the Palestinian children considered “below level” – or “not on track” in their early childhood development is higher than their peers in neighbouring countries. This research presents a framework to explain pathways between water stress, child health, family wealth, parental support, and early childhood development in Palestine, and presents a different perspective in water stress and policies and services addressing children. Objective: To assess evidence of the link between water stress and vulnerability in early childhood development and to examine the implications of this relationship for services and policies in Palestine. Method and Results: Demographic and health data obtained from nationally representative surveys were merged and analysed. Descriptive analysis was used to investigate the features of household water stress and show its association with risk for delayed early childhood development in Palestine. Data on social, economic, health, and environmental conditions in 52 communities in Palestine were aggregated to develop a Child-Water Stress Index to be used as a single summary measure that captures the multidimensional influence of water stress. At the household level, a Mediation Model was developed and applied to investigate the pathways through which water stress interacts with child health, family care, and wealth level and in turn, influences early childhood development. An evaluation strategy is presented, with new perspectives for enhancing the effectiveness of early childhood programmes and policies in the Palestinian context. Qualitative data using focus group discussions with parents and semi structured interviews with practitioners were conducted to provide in depth analysis of the findings. Conclusion: Children experiencing water stress are more likely to not be on track in their early childhood development. Water stress is more likely to influence childhood development through indirect pathways by interacting with determinants of optimal early childhood development including disrupted family support, wealth level, and child health. Water stress exacerbates the impact of limited wealth and inadequate family support on early childhood health and development, suggesting the need for a holistic perspective in evaluating services and policies

The Global Risks Report 2016, 11th Edition

Now in its 11th edition, The Global Risks Report 2016 draws attention to ways that global risks could evolve and interact in the next decade. The year 2016 marks a forceful departure from past findings, as the risks about which the Report has been warning over the past decade are starting to manifest themselves in new, sometimes unexpected ways and harm people, institutions and economies. Warming climate is likely to raise this year's temperature to 1° Celsius above the pre-industrial era, 60 million people, equivalent to the world's 24th largest country and largest number in recent history, are forcibly displaced, and crimes in cyberspace cost the global economy an estimated US$445 billion, higher than many economies' national incomes. In this context, the Reportcalls for action to build resilience – the "resilience imperative" – and identifies practical examples of how it could be done.The Report also steps back and explores how emerging global risks and major trends, such as climate change, the rise of cyber dependence and income and wealth disparity are impacting already-strained societies by highlighting three clusters of risks as Risks in Focus. As resilience building is helped by the ability to analyse global risks from the perspective of specific stakeholders, the Report also analyses the significance of global risks to the business community at a regional and country-level

TRANSFORMATION AND RESILIENCE AT SHURI-JO: DEFINING A GENOME OF PLACE

The 1970s is widely regarded as the decade of environmental awakening in America. But many of the critical variables that later informed this ongoing conversation were mobilized in the faraway island of Okinawa, Japan's southernmost prefecture that became a new territory of the United States by virtue of their victory in World War II (WWII). The same powerful military machine that destroyed much of Japan reorganized itself into a nation-building enterprise focused on restoring and reorienting the country into a model democracy. This dissertation will construct an interactive design framework that focuses on the creation of Okinawa's new university as a microcosm of the exchanges that redefined the island's most important cultural icon. In addition to the military government, I will illustrate how visiting professors from Michigan State University interacted with Okinawan educators to shape the University of the Ryukyus (Ryudai), a new land-grant university that produced transformative changes that reached far beyond the campus boundaries. I will demonstrate that Ryudai's post-war redevelopment period, however, takes on more profound implications of sustainability if contextualized within a "genome of place" that explores biotic, abiotic, social, and economic influences across space and time. Built on the sacred grounds of Shuri-jo, the destroyed 14th century castle, the Ryudai campus was eventually dismantled and relocated to a larger site when Okinawa reverted to Japanese sovereignty in 1972. This dissertation argues that the resilience of post-war Okinawa was symbolized by the radical transformation of the Shuri-jo site and that by disentangling the many layers of this palimpsest, its meaning may transcend its short timeframe. A critical inquiry of textual and visual materials will articulate how Shuri-jo became an iconic Cold War site where Eastern and Western cultures intersected, modernism and traditionalism converged, and natural and human systems collided. By locating the mid-century university experiment within a centuries-old context, I will also illustrate how its successes and failures may inform Okinawa's political future as it inherits several decommissioned military sites from the U.S. government
