Adaptivity for knowledge content in the semantic web
(2008)The focus of this report is the adaptivity issue for Learning Objects owned by Learning (Web) Services. We address this issue based on the Concept, Resource, Order, Product (CROP) Reference Architecture that we briefly ... -
Applications of Informatics in a Leonardo da Vinci project with reference to the organic farming in Greece and Europe
(2011)The market of organic products in Europe is generally expanding. The organic food production has been strictly regulated in the European Union. Particular competence requirements need to be developed not only to achieve ... -
Automating data management in heterogeneous systems using polyhedral analysis
(2015)In this paper we introduce a framework which automates the task of data management for OpenCL programs across multiple devices of a heterogeneous system. Our approach uses compile-time analysis, based on the polyhedral ... -
A comparable study employing weka clustering/classification algorithms for web page classification
(2011)Documents and web pages share many similarities. Thus classification methods used in documents can be applied to advanced web content, with or even without modifications. Algorithms for document and web classification are ... -
A comparison over focused web crawling strategies
(2011)In this paper we review and compare focused crawling strategies, studied and published during the past decade. Despite giant leaps in communication, storage and computing power in recent years, crawlers have always struggled ... -
Computer-based methods in environmental data organization and management
(2000)The protection of the environment is one of the main problems that mankind faces today. Recent advances in computer technology have assisted environmental studies towards this direction, in various scientific approaches. ... -
A cooperative protocol for spectral-efficient cognitive relay networks
(2014)In this paper we propose a cooperative protocol for cognitive wireless networks that can improve the overall system spectral efficiency when a secondary user (SU) incorrectly transmits over the same resource with the primary ... -
The deletion operation in xBR-trees
(2012)In order to design a spatial index, the most important operations are: insertion, deletion and search. We focus on the deletion operation over the xBR-tree, a spatial data secondary memory structure that belongs to the ... -
A diet-guide mobile application for diabetes mellitus management
(2015)Modern nutritional habits have caused the dramatic increase in diabetes mellitus cases, predominantly in developed countries. Diabetes, which is characterized by high blood sugar levels over a prolonged period, is mainly ... -
Factors in the university - City interaction: The case of Greek Regional Universities
(2009)The complex interdependence / interaction relations between the academic and local communities - mainly in terms of their potential contribution to the development of the university and the city - have been the object of ... -
A fair scheduling policy for wireless channels with intermittent connectivity
(2008)We consider a system of parallel queues with the constraint that only one queue can be served at a time. Each queue can be served through a wireless channel with intermittent connectivity. We propose a policy which serves ... -
Hardware synthesis of high-level C constructs
(2015)In this paper, experiments with a useable C frontend for the CCC behavioural synthesis tools are presented and analysed. This tool combination is able to rapidly deliver provably-correct hardware implementations at the RTL ... -
i-Protect: An open source emergency management framework
(2011)Emergency management is an essential capability in modern society. As disasters can happen at any time and can differ from each other considerably, it is necessary to develop a supple framework which can comply with each ... -
Information science instruction and changes in girls' and boy's expectancy and value beliefs: In search of gender-equitable pedagogical practices
(2013)In this study, which was situated in the context of information science instruction, data were collected twice using student self-reports to examine the effects of pedagogical practices on changes in boys' and girls' ... -
Managing forest fires with i-protect fire simulation module
(2012)Emergency management is an essential capability in modern society. As disasters can happen at any time and can differ from each other considerably, it is necessary to develop a supple framework which can comply with each ... -
Minimum weighted clustering algorithm for wireless sensor networks
(2015)Extending network lifetime is a primary design objective for a wireless sensor network (WSN). Efficient clustering among sensor nodes seems a promising solution to evenly balance energy consumption and thus extend node and ... -
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 ... -
Nearest Neighbor Algorithms using xBR-Trees
(2011)One of the common queries in spatial databases is the (K) Nearest Neighbor Query that discovers the (K) closest objects to a query object. Processing of spatial queries, in most cases, is accomplished by indexing spatial ... -
On formulating and tackling Integrated circuit placement as a scheduling problem
(2015)Integrated circuit (IC) placement consists of placing the cells of the IC on a chip plane so that overall performance is optimized. Various performance criteria have been considered with the most common being wire length. ... -
Optimal cooperative content placement algorithms in hierarchical cache topologies
(2012)The tremendous growth in the use of the World Wide Web and the expansion of Video On Demand and IPTV services increase the bandwidth demands, enforcing the creation of congestion in Internet's links and the experience of ...
