This article presents a unified computing, caching, and communication (3C) solution for the upcoming 5G environment that will allow service, content, function providers to deploy their services/ content/functions near end users (EUs); network virtually connectivity services over commodity hardware; enable renounce role as passive stakeholders become active ones by offering 3C resources ecosystem. In this direction, we foresee exploitation of peer-topeer- like middleware/app upon installation...
Currently there is an active debate about how the existing cloud paradigm can cope with volume, variety, and velocity of data generated by end devices (e.g., Internet Things sensors). It expected that will be over 50 billion these 2020, which create more than two Exabytes worth each day. Additionally, vast number edge a huge ocean digital resources close to source, which, however, remain so far unexploited their full extent. EXEGESIS proposes harness unutilized via three-layer architecture...
Entity Resolution constitutes a core task for data integration that, due to its quadratic complexity, typically scales large datasets through blocking methods. These can be configured in two ways. The schema-based configuration relies on schema information order select signatures of high distinctiveness and low noise, while the schema-agnostic one treats every token from all attribute values as signature. latter approach has significant potential, it requires no fine-tuning by human experts...
The authors present a method for the design of 2-D zero-phase finite-impulse-response (FIR) fan filters with quadrantal symmetry using McClellan transform. They give conditions that coefficients transform must satisfy in order to avoid scaling proposed satisfies these conditions. resulting cut-off isopotential is shown have very small relative absolute deviation from ideal one. extended FIR general shape.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML"...
The architecture of an indoor target localization system employing a small number infrared-emitting diodes and sensors is presented in this paper. properties infrared light magnetic fields have already been exploited for position distances several centimeters. Ultrasonic waves laser can be used longer distance estimation if the capable accurately measuring time flight reflected signals. proposed approach intends to cover meters without requiring high accuracy measurements increased...

In this paper we present NAND gates designed using single electron logic. First the single-electron behaviour is studied and then energy performance of circuit examined. The whole design simulation made a Monte-Carlo based tool. results proved that circuits were behaving as gates, while free study system stability diagram verified correct functioning circuit.
Peer to (P2P) systems, have been identified as one of the main contributors exponential growth internet traffic. File sharing applications such BitTorrent clients, are most popular among P2P systems and tend consume great amounts network resources, stretching infrastructure capabilities their limits. This causes interdomain links be overloaded with traffic, created from content traversing network, which is times redundant. Cloud computing has an empowering force towards alleviating this...
Alongside the rapid expansion of Internet Things (IoT), and network evolution (5G, 6G technologies), comes need for security higher level less hardware demanding modules. New cryptographic systems are developed, in order to satisfy special needs security, that have emerged modern applications.
