Automated skin lesion assessment using mobile technologies and cloud platforms
(2012)This paper presents a smart phone based system for storing digital images of skin areas depicting regions of interest (lesions) and performing self-assessment of these skin lesions within these areas. The system consists ... -
CARROT - A tool for fast and accurate soft error rate estimation
(2006)We present a soft error rate (SER) analysis methodology within a simulation and design environment that covers a broad spectrum of design problems and parameters. Our approach includes modeling of the particle hit at the ... -
A channel model for the propagation of X-band radio waves through the solar corona
(2017)Spacecraft communication systems operating at X-band are strongly affected when the propagation path passes close to the sun (characterised by the Sun-Earth-Probe, SEP, angle). In this paper, a channel model that can ... -
Corrosion-induced hydrogen embrittlement in aluminum alloy 2024
(2006)The present paper focuses on the observed corrosion-induced embrittlement of alloy 2024 and tries to answer the key question on whether the observed embrittlement is attributed to hydrogen uptake and trapping in the material. ... -
Detecting Influential Spreaders in Complex, Dynamic Networks
(2013)A hybrid of node degree and k-shell index is more effective at identifying influential spreaders and has less computational overhead than either of these traditional measures. -
Determining the driving factors of Commuting: An empirical analysis from greece
(2013)Commuting refers to the act of daily traveling, between two locations, for employment purposes and suggests a multidimensional phenomenon in Regional Science, which is determined by social, economic, geographic and political ... -
Energy Efficiency through Significance-Based Computing
(2014)An extension of approximate computing, significance-based computing exploits applications' inherent error resiliency and offers a new structural paradigm that strategically relaxes full computational precision to provide ... -
Failure analysis and fatigue life assessment of a redesigned aircraft landing gear component
(2013)The present study deals with the failure analysis, the redesign and the fatigue life assessment of a rod end component of the North American T-2 jet trainer aircraft, nose landing gear (NLG) system. The rod ends suffer ... -
Failure mechanisms of landfills under dynamic loading
(2008)Seismic stability of above-ground landfills is an issue of extreme engineering interest, and the proper implementation of the corresponding analyses requires dealing with several uncertainties related mainly to the special ... -
Hydrogen absorption into aluminum alloy 2024-T3 during exfoliation and alternate immersion testing
(1998)Exfoliation and alternate immersion corrosion were investigated in Al alloy 2024-T3 (UNS A92024) uptake during exposure and to correlate it with corrosion characterization. Characterization involved determination of weight ... -
Identification of classes of H-matrices
(2010)H-matrices play an important role in the theory and applications. Different algorithms to determine H-matrices can be found in the literature. In [1] an algorithm is given, and this algorithm can determine if an irreducible ... -
Improving opinionated blog retrieval effectiveness with quality measures and temporal features
(2014)The massive acceptance and usage of the blog communities by a significant portion of the Web users has rendered knowledge extraction from blogs a particularly important research field. One of the most interesting related ... -
IRaaS: A cloud implementation of an interface relaxation method for the solution of PDEs
(2015)The solution of composite Partial Differential Equations is an indispensable step in numerous scientific applications. However, this is a computationally and memory demanding process for large-scale differential equations. ... -
Joint Time-Domain Resource Partitioning, Rate Allocation, and Video Quality Adaptation in Heterogeneous Cellular Networks
(2015)Heterogenous cellular networks (HCN) introduce small cells within the transmission range of a macrocell. For the efficient operation of HCNs it is essential that the high-power macrocell shuts off its transmissions for an ... -
Modeling and solution approach for the environmental traveling salesman problem
(2014)We consider the environmental traveling salesman problem in a connected graph driven by a cost function describing the impact of environmental externalities over the routes. The resulting problem is the asymmetric non-Euclidean ... -
On the effect of hydrogen on plastic instabilities in metals
(2003)Experimental observations and theoretical calculations have demonstrated that hydrogen solute atoms increase the dislocation mobility in metals and alloys, thus promoting highly localized plastic processes which eventually ... -
Pareto optimal structural models and predictions consistent with data and modal residuals
(2008)A multi-objective identification method for model updating based on modal residuals is proposed. The method results in multiple Pareto optimal structural models that are consistent with the measured modal data, the class ... -
Prefetching in content distribution networks via web communities identification and outsourcing
(2008)Content distribution networks (CDNs) improve scalability and reliability, by replicating content to the "edge" of the Internet. Apart from the pure networking issues of the CDNs relevant to the establishment of the ... -
Software Features Prioritization based on Stakeholders' Satisfaction/Dissatisfaction and Hesitation
(2020)In this paper we present a practical method that can be applied to support the prioritization of large sets of candidate software features in a requirements prioritization process. We consider as prioritization criteria ...
