Appraisal of road pavement evaluation methods
(2019)Road pavement evaluation methods are based either on simple index of a surface characteristic, such as International Roughness Index (IRI) for roughness, Rut Depth (RD) for rutting, Sideway Force Coefficient (SFC) for ... -
Backbone formation in military multi-layer ad hoc networks using complex network concepts
(2016)Modern battlefields are characterized by increasing deployment of ad hoc communications among allied entities. These networks can be seen as a complex multi-layer ad hoc network, where each layer may be an independently ... -
Backward Degree a new index for online and offline change point detection based on complex network analysis
(2022)How to identify an upcoming transition in a time series continues to be an important open research issue. In various fields of physical sciences, engineering, finance and neuroscience abrupt changes can occur unexpectedly ... -
Black virus decontamination of synchronous ring networks by initially scattered mobile agents
(2020)We study the Black Virus Decontamination problem in ring topologies for initially scattered mobile agents. In this problem a number of mobile agents operate in a network where one of its nodes u is hostile (contaminated) ... -
Capturing system dynamics using complex networks and granger causality analysis: Application to environmental data
(2016)In the present study, we introduce a novel methodology to analyze environmental observations. Environmental phenomena are usually complex and the majority of them present nonlinear behavior. In the first part of the present ... -
The Complexity in the Study of Spatial Networks: an Epistemological Approach
(2018)Provided that the study of complex networks has reached a crucial measure to be considered by many researchers as a separate discipline, the so-called Network Science (NS), the assessment of this field under the epistemological ... -
Computing scientometrics in large-scale academic search engines with MapReduce
(2012)Apart from the well-established facility of searching for research articles, the modern academic search engines also provide information regarding the scientists themselves. Until recently, this information was limited to ... -
Daily multivariate forecasting of water demand in a touristic island with the use of artificial neural network and adaptive neuro-fuzzy inference system
(2016)Water demand forecast has emerged as an imperative component of intelligent Internet and Communication Technologies based methodologies of water management. The need of increased time resolution of forecast in order to ... -
Deep learning in water resources management: The case study of Kastoria lake in Greece
(2021)The effects of climate change on water resources management have drawn worldwide attention. Water quality predictions that are both reliable and precise are critical for an effective water resources management. Although ... -
Demo: Lora mesh network experimentation in a city-wide testbed
(2019)LoRa is a low-power long-range Internet of Things (IoT) standard that offers remarkable performance, especially in remote rural areas. However the single-hop nature of current LoRa networks, poses significant challenges ... -
Design Space Exploration of a Sparse MobileNetV2 Using High-Level Synthesis and Sparse Matrix Techniques on FPGAs
(2022)Convolution Neural Networks (CNNs) are gaining ground in deep learning and Artificial Intelligence (AI) domains, and they can benefit from rapid prototyping in order to produce efficient and low-power hardware designs. The ... -
Distributed cache management in information-centric networks
(2013)The main promise of current research efforts in the area of Information-Centric Networking (ICN) architectures is to optimize the dissemination of information within transient communication relationships of endpoints. ... -
Dynamics and causalities of atmospheric and oceanic data identified by complex networks and Granger causality analysis
(2018)Understanding the underlying processes and extracting detailed characteristics of spatiotemporal dynamics of ocean and atmosphere as well as their interaction is of significant interest and has not been well thoroughly ... -
Effects in the network topology due to node aggregation: Empirical evidence from the domestic maritime transportation in Greece
(2018)This article studies the topological consistency of spatial networks due to node aggregation, examining the changes captured between different network representations that result from nodes’ grouping and they refer to the ... -
Efficient file replication in large wireless networks with dynamic popularity
(2014)We investigate the problem of replication in large wireless networks that employ caching in the case of a single file whose popularity varies with time. As opposed to the case of static popularity, in this case for the ... -
An Efficient Localization and Avoidance Method of Jammers in Vehicular Ad Hoc Networks
(2022)Jamming is a terrifying attack that could harm 802.11p-based vehicular communications by occupying the communication channels by overwhelming the network with jamming packets, especially for self-driving cars, as it is ... -
