Among them, Ruđer Bošković and Nikola Tesla are unique and exceptional due to their scientific originality in comprehending basic laws and concepts of nature and a great number of fundamentally original visions in science and technology. Their scientific and technological ideas and innovations used to seem persistently applied for which mankind owes them a debt of gratitude. Ruđer Bošković, a great scientist and philosopher, wrote works and opuscules in philosophy of nature, mathematics, physics and technique areas in his books, which in turn inspired and stirred an intuition of another great scientific innovator – Nikola Tesla. The two gifted, top-notch intellectuals may form a synergy despite the fact that the time distance between them spanned one and a half centuries. A synergy drew over the natural science and technique, inspired a genuine vortices towards a new visions in the ...

In this paper, the Dew Computing is described and recognized as a new structural layer in the existing distributed computing hierarchy. In the existing computing hierarchy, the Dew computing is positioned as the ground level for the Cloud and Fog computing paradigms. Vertical, complementary, hierarchical division from Cloud to Dew Computing satisfies the needs of high- and low-end computing demands in everyday life and work. These new computing paradigms lower the cost and improve the performance, particularly for concepts and applications such as the Internet of Things (IoT) and the Internet of Everything (IoE). In addition, the Dew computing paradigm will require new programming models that will efficiently reduce the complexity and improve the productivity and usability of scalable d...

Fog computing can provide a higher level of user experience due to its geographic and network topology location and distribution. IoT services also need to be managed seamlessly to ensure adequate QoS (due to the mobility of devices or the temporary periods without an internet connection). Such domains are combined under the auspices of Dew computing, as in critical cases, extending an IoT service to the end user’s device is a feasible task. Such scenarios can hardly be investigated at a large scale due to the lack of dedicated simulation environments. In this paper, we present an extension of the DISSECT-CF-Fog simulator with a Dew computing model, to enable the simulation of IoT-Dew-Fog systems in a cost-effective manner. In particular, we focus on service migration options for mobile devices and cases with tempor...

This trend of so-called "digitalisation" is penetrating every pore of human civilisation, including nature, people, and machines; our economy and production, which must be as local as possible; and our global ecology. The use of information processing technology brings benefits to a wide range of endeavours. In this sense, many computing technologies and techniques must be used to achieve the goal of an integrated global service ecosystem, a Rainbow ecosystem of all hierarchical levels of computing. One of the most important new developments in recent years is the development of blockchain technology. A blockchain can solve many problems of persistent and traceable storage, as well as enable direct coordination, compensation, etc. Therefore, in the Dew-Fog-Cloud hierarchy, blockchain technology is a promising new approach to enable novel applications in a variety of f...

Unintentionally, and with little or no self-awareness, computer science has crept into every aspect of life, or, better to say, almost every aspect of the natural and social environment has crept into the lap of computer science. Somehow much in the world today came to be the responsibility of Computer Science. Unfortunately, the development was so rapid and mostly stochastic that most of us, computer scientists and computer engineers, application, software and computing paradigm inventors and developers, did not even have a chance yet to realise the Responsibility we are taking on. The ecosystems we live in, from the ecosystem of the family to the ecosystem of social groups and groupings, from the ecosystem of the human body itself, to the ecosystem of the globaly interdependent economics, and from the ecosystem of the living beings sharing this world with us, up to the ecosystem of the whole Earth, those ecosystems are more and more being monitored, controlled and even steered by a mirriad of human-produced artifacts, all-pervasively being based on data processing equipment, or, commonly said, computers. It is very obvious that in modern days computer science leads an extremely influential role in all these ecosystems. It is also obvious that for its ideas and actions in those fields computer science has to take responsibility. In the overall “computing” ecosystem there is actually a kind of “evaporation” of information and requests upwards from Nature to Dew to Human to Fog to Cloud, and a “rain” of services and processed information from the Cloud downwards. Therefore the associative name of Rainbow – as an analogy to the sunray spectrum – an ecosystem in which we necessarily include both the “technical” and the “philosophical” aspects, or, in other words, both the Machines and the Humans. A consistent, robust and properly defined Rainbow Ecosystem will offer new possibilities of knowledge development and information usage for a very broad user base, it will enable proper maintenance of essential natural and human-generated ecosystems, and enable huge savings in many areas of effort, as well as providing novel applications and actively respond to changing economy, supply and business needs, while keeping the Global Ecosystem in natural balance. Proper and responsible cooperation between humans, machines, the environment and the nature, with the aim of freedom, security, prosperity and true betterment of life, is the only way forward.

For computing and data processing there are individual Computers, their Clusters, Grids, and, finally, the Clouds. For pure data communication there is the Internet, and for the Human-understandable Information Communication for example the World Wide Web. The rapid development of hand-held mobile devices with high computational capabilities and Internet connectivity enabled certain parts of Clouds to be “lowered” into the so called “thin clients”. This led to development of the Fog-Computing Paradigm as well as development of the Internet of Things (IoT) and Internet of Everything (IoE) concepts. However, the most significant amount of information processing all around us is done on the lowest possible computing level, outright connected to the physical environment and mostly directly controlling our human immediate surroundings. These “invisible” information processing devices we find in our car's motor, in the refrigerator, the gas boiler, air-conditioners, wending machines, musical instruments, radio-receivers, home entertainment systems, traffic-controls, theatres, lights, wood-burning stoves, and ubiquitously all over the industry and in industrial products. These devices, which are neither at the cloud/fog edge, nor even at the mobile edge, but rather at the physical edge of computing are the basis of the Dew Computing Paradigm. The merits of seamlessly integrating those “dew” devices into the Cloud - Fog - Dew Computing hierarchy are enormous, for individuals, the public and industrial sectors, the scientific community and the commercial sector, by bettering the physical and communicational, as well as the intellectual, immediate human environment. In the possibility of developing integrated home management/entertainment/maintenance systems, self-organising traffic-control systems, intelligent driver suggestion systems, coordinated building/car/traffic pollution control systems, real-time hospital systems with all patient and equipment status and control collaborating with the medical staff, fully consistent synaesthetic artistic performances including artists and independent individuals (“active public”) from wide apart, power distribution peek filtering, self-reorganisation and mutual cooperation systems based on informed behaviour of individual power consumption elements, emergency systems which cooperate with the town traffic, etc., etc., the Dew-Computing paradigm shows the way towards the Distributed Information Services Environment (DISE), and finally towards the present civilisation's aim of establishment of a Global Information Processing Environment (GIPE). It is therefore essential, through Research, Innovation and Development, to explore the realm of possibilities of Dew Computing, solve the basic problems of integration of the “dew” level with the higher level Dew-Fog-Cloud hierarchy, with special attention to the necessity of information (not only data) processing and communication, and demonstrate the viability and high effectiveness of the developed architecture in several areas of human endeavour through real life implementations. The present scientific and technological main objective is to provide the concepts, methods and proof-of-concept implementations that are moving Dew Computing from a theoretical/experimental concept to a validated technology. Finally, it will be necessary to define and standardise the basics of the Dew Computing Architecture, Language and Ontology, which is a necessity for the seamless integration of the emerging new Global Information Processing Architecture into the Fog and Cloud Paradigms, as a way towards the above mentioned civilisation goals.

Common computers are capable of calculating more than 50,000 million instructions per second. Currently the biggest obstacle in computer usage is slow communication between the human and the computer. With innovation and development of novel (natural based) sensors capable of capturing positions and natural motion of human body a new, natural, way of interacting with computer is enabled. This paper gives an overview of eye tracking technology, and presents its application in nature based human-computer interaction (HCI) systems by extending standard controllers, such as the keyboard and the mouse. Novel approaches enable HCI closer to the communication patterns of human beings. In addition, the usage of those concepts in applications for eye diseases and disorders diagnostics and rehabilitation is discussed.

The system consists of a high-resolution offline 3D scanner and a real-time low-resolution 3D scanner, both of them paired together with a thermal imaging camera. The emphasis of this paper is the presentation of the novel concept of the standardisation of human body 3D thermal models, captured by the multi-resolution real-time 3D thermal imaging system. The standardisation procedure utilises skeleton detection, skeleton transformation, mesh optimisation and texture mapping. The presented concept enables novel and practical methods for human body 3D thermal models comparison and analysis.
