In-memory k nearest neighbor GPU-based query processing
(2020)The k Nearest Neighbor (k-NN) algorithm is widely used for classification in several application domains (medicine, economy, entertainment, etc.). Let a group of query points, for each of which we need to compute the k-NNs ... -
An information system for judicial and public administration using artificial intelligence and geospatial data
(2017)The adoption of information technology in judicial and public administration has become a major need nowadays with the rapid growth of information regarding managerial issues. This paper presents an advanced methodology ... -
The K group nearest-neighbor query on non-indexed RAM-resident data
(2016)Data sets that are used for answering a single query only once (or just a few times) before they are replaced by new data sets appear frequently in practical applications. The cost of buiding indexes to accelerate query ... -
Limiting the impact of statistics as a proverbial source of falsehood
(2019)This paper presents an early version of a decision-making “eco” system. We refer to it as an “eco” system because it is primarily based on mathematical logic and combines concepts and principles from the fields of statistics, ... -
Live Vessels' Monitoring using Geographic Information and Internet of Things
(2022)The purpose of this paper is to present the GIS Vessels Monitoring Platform, an integration platform, which collects information from various, heterogeneous internal and external sources and represents the collected ... -
Machine learning for all: A more robust federated learning framework
(2019)Machine learning and especially deep learning are appropriate for solving multiple problems in various domains. Training such models though, demands significant processing power and requires large data-sets. Federated ... -
Moving Towards a Blockchain-Based Healthcare Information System
(2019)One of the major problems that a national health system face is the lack of a unified clinical data management. In Greece, the critical and sensitive medical data generated during a patient lifetime are fragmented in one ... -
Multi-dimension diversification in legal information retrieval
(2016)The number of freely available legal data sets is increasing at high speed. Citizens can easily access a lot of information about regulations,court orders,statutes,opinions and analytical documents. Such openness brings ... -
A multilateral design process of decision support systems: Some issues
(2005)A discussion is presented of why some Decision Support Systems (DDS) that some firms have developed cannot satisfy the users' needs. Trying to develop a specific Decision Support System (DSS) for Vehicle Routing and ... -
Network analysis in the legal domain: A complex model for European Union legal sources
(2018)Legislators, designers of legal information systems, as well as citizens face often problems due to the interdependence of the laws and the growing number of references needed to interpret them. In this article, we introduce ... -
Normative conflicts:Patterns,detection and resolution
(2009)The analysis, representation and management of normative conflicts have been the focus of much research in recent years in commercial and business applications. In this paper we are concerned with normative conflicts that ... -
On green scheduling for desktop grids
(2018)Task scheduling is of paramount importance in a desktop grid environment. Earlier works in the area focused on issues such as: meeting task deadlines, minimizing make-span, monitoring and checkpointing for progress, malicious ... -
On the information diffusion between web-based social networks
(2015)The topic of Information diffusion has been in the centre of sociology interest for many years. Even before the rise of Online Social Networks (OSNs), social ties and the way the information flows have been studied in ... -
On the optimal processor assignment for computing the steady state kalman filter in parallel and distributed systems
(2017)Kalman filters have many practical applications in various fields such as sensor networks, image and video processing. Therefore, their fast computation is of paramount importance. In this paper distributed implementations ... -
Plane-sweep algorithms for the K Group Nearest-Neighbor Query
(2015)One of the most representative and studied queries in Spatial Databases is the (K) Nearest-Neighbor (NNQ), that discovers the (K) nearest neighbor(s) to a query point. An extension that is important for practical applications ... -
Predicting woody plant diversity as key component of ecosystems: A case study in central Greece
(2019)The Mediterranean basin is a global hotspot of biodiversity. Woody plants are key components of ecosystems. This article explores the environmental impacts on woody plant species richness and diversity in maquis and abandoned ... -
Predictive join processing between regions and moving objects
(2008)The family of R-trees is suitable for indexing various kinds of multidimensional objects. TPR*-trees are R-tree based structures that have been proposed for indexing a moving object database, e.g. a data-base of moving ... -
Representation of lattices with modal operators in two-sorted frames
(2019)We study general lattices with normal unary operators for which we prove relational representation and duality results. Similar results have appeared in print, using Urquhart's lattice representation, by the second author ... -
SliceNBound: Solving closest pairs and distance join queries in apache spark
(2017)The (K) Closest-Pair(s) Query, KCPQ, consists in finding the (K) closest pair(s) of objects between two spatial datasets. Recently, several systems that enhance Apache Spark with spatial-awareness have been presented, ... -
