Due to the rapid paradigm shift in Internet of Things networks from wired and centralized flexible wireless decentralized networks, building effective reliable distributed consensus mechanisms over is becoming essential. Especially, since performance communication endpoints a large-scale network limited by their capability, it requires careful co-design attain fast scalable mechanism with high ...

Sodium-ion batteries are a promising class of secondary power sources that can replace some the lithium-ion, lead–acid, and other types in large-scale applications. One critical parameters for their potential use is high efficiency wide temperature range, particularly below 0 °C. This article analyzes phase equilibria electrochemical properties sodium-ion battery electrolytes based on NaPF6 sol...

With the booming proliferation of user requests in Internet Things (IoT) network, Edge Computing (EC) is emerging as a promising paradigm for provision flexible and reliable services. Considering resource constraints IoT devices, some delay-aware requests, heavy-workload device may not respond on time. EC has sparked popular wave offloading to edge servers at network. The orchestration user-req...

This paper presents a networking testbed, which is developed within the EC FP7 project SANDRA to test and validate IPv6-based protocols for future Air Traffic Management (ATM) network. The development was originally initiated within the EC FP6 project NEWSKY which aimed at developing a concept for a global, heterogeneous communication network for aeronautical communications, based on IPv6 proto...

This paper is devoted to the non-symmetric channels. Here we will present t-EC-AUED codes. Böinck and van Tilborg gave a bound on the length of binary t-EC-AUED codes. A generalization of this bound to arbitrary alphabet size is given. This generalized Böinck van Tilborg bound, combined with constructions, is used to determine the length of some optimal binary and ternary t-EC-AUED codes. The s...

Evolutionary Computation (EC) is now a few decades old. The impressive development of the field since its initial conception has made it one of the most vigorous research areas, specifically from an applied viewpoint. This should not hide the existence of some major gaps in our understanding on these techniques. In this essay we propose a number of challenging tasks that –according to our opini...

Ultra-dense networks (UDNs) provide a promising paradigm to cope with exponentially increasing mobile traffic. However, little work has to date considered unsaturated traffic with quality-of-service (QoS) requirements. This paper presents a new cross-layer analytical model to capture the unsaturated traffic of a UDN in the presence of QoS requirements. The effective capacity (EC) of the UDN is ...

Auditory cortex functioning is an important factor of successful rehabilitation after cochlear implantation, particularly in partially deafened patients who have to integrate the natural acoustic hearing with the electric one. This subject has not yet been properly recognized, especially regarding the auditory cortex’ tonotopic organization in such patients. Method: Material included 20 patient...
