Improved retrieval effectiveness by efficient combination of term proximity and zone scoring: A simulation-based evaluation
(2012)During the past few years, the commercial Web search engines have augmented their underlying index structures by significantly enriching the information which describes the appearance of a word within a document Dean (2009) ... -
A knowledge discovery methodology for behavior analysis of large-scale applications on parallel architectures
(2003)The focus of this paper is the application and extension of the knowledge discovery in databases process [5] developed in PYTHIA recommender system, to analyze the behavior of a DOE ASCI application/hardware pairs in the ... -
Lifespan and propagation of information in On-line Social Networks: A case study based on Reddit
(2015)Since 1950, information flows have been in the center of scientific research. Up until the Internet penetration in the late 1990s, these information flow studies were based on traditional offline social networks. From the ... -
LR-tree: A logarithmic decomposable spatial index method
(2003)Since its introduction in 1984, R-tree has been proven to be one of the most practical and well-behaved data structures for accommodating dynamic massive sets of geometric objects and conducting a very diverse set of queries ... -
METRADISC-XL: A program for meta-analysis of multidimensional ranked discovery oriented datasets including microarrays
(2012)A comprehensive software for performing meta-analysis of ranked discovery oriented datasets, such as those derived from microarrays or other high throughput technologies, and for testing between-study heterogeneity for ... -
A neural network approach for the solution of frictional contact problems with nonconvex superpotentials
(2002)A neural network approach is proposed for the numerical treatment of frictional contact problems. A nonmonotone friction law is assumed to describe the stick-slip process which leads to the formulation of a computational ... -
Normative conflicts in electronic contracts
(2011)We are concerned with normative conflicts that arise for agents engaging in electronic contracting within an electronic marketplace. We identify a set of primitive conflict patterns, examine other analyses of conflicts ... -
A novel tool for segmenting 3D medical images based on generalized cylinders and active surfaces
(2013)Three-dimensional (3D) medical imaging has been incorporated in routine clinical practice, since the required infrastructure has become increasingly affordable. New algorithms and applications are needed to serve the ... -
Overview of Advanced Computer Vision Systems for Skin Lesions Characterization
(2009)During the last years, computer-vision-based diagnosis systems have been used in several hospitals and dermatology clinics, aiming mostly at the early detection of skin cancer, and more specifically, the recognition of ... -
Parallel short range molecular dynamics simulations on computer clusters: Performance evaluation and modeling
(2005)This paper describes the performance of a portable molecular dynamics code running on an eight-node PC cluster. The molecular dynamics code is based on the atom decomposition method for distributing the computation load ... -
Partitioning elements of the Periodic Table via fuzzy clustering technique
(2004)In this paper we present fuzzy clustering results of the elements of the Periodic Table according to several physical properties related directly to their electronic structure (ionization potential, cohesion energy, ... -
Real time enhanced random sampling of online social networks
(2014)Social graphs can be easily extracted from Online Social Networks (OSNs). However, as the size and evolution of this kind of networks increases over time, conventional sampling methods used to evaluate large graph information ... -
Service configuration and traffic distribution in composite radio environments
(2004)This paper adopts the assumption that cellular, broadband fixed wireless access (BFWA), wireless local area networks (WLAN), and digital video broadcasting (DVB) systems can be co-operating components of a composite-radio ... -
A simulation-based performance evaluation of a randomized MIS-based clustering algorithm for ad hoc networks
(2014)Ad-hoc networks represent distributed systems that comprise wireless nodes which can dynamically self-organize into arbitrary and temporary network topologies, without relying on pre-existing infrastructure, and thus network ... -
Solution of interface problems with nonmonotone contact and friction laws using a neural network optimization environment
(2004)The paper addresses the solution of interface problems which present a degrading behaviour leading to nonmonotone contact and friction laws. The paper is based on a superpotential formulation that leads to hemivariational ... -
Strengths and Weaknesses of 1.5T and 3T MRS Data in Brain Glioma Classification
(2011)Although magnetic resonance spectroscopy (MRS) methods of 1.5Tesla (T) and 3T have been widely applied during the last decade for noninvasive diagnostic purposes, only a few studies have been reported on the value of the ... -
Support Vectors Machine-based identification of heart valve diseases using heart sounds
(2009)Taking into account that heart auscultation remains the dominant method for heart examination in the small health centers of the rural areas and generally in primary healthcare set-ups, the enhancement of this technique ... -
Virtual reality: The non-temporal cartographic animation and the urban (large) scale projects
(2005)The evolution of digital technology has placed cartography in a dialog on questions concerning the new abilities, its form and prospective. The cartographic presentation in three dimensions has as a basic feature: the ...
