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 ... -
An ANN approach on the optimization of the cutting parameters during CNC plasma-arc cutting
(2010)The objective of the present study is to develop an Artificial Neural Network (ANN) in order to predict the bevel angle (response variable) during CNC plasma-arc cutting of St37 mild steel plates. The four (4) input ... -
Applications of earth-to-air heat exchangers: A holistic review
(2022)The building sector is responsible for 40% of primary energy consumption, with heating/cooling covering the most significant portion. Thus, passive heating/cooling applications have gained significant ground during the ... -
Applying pressure management to reduce water losses in two greek cities' WDSs: Expectations, problems, results and revisions
(2014)An overall pressure management project applied in two (Kos and Kozani) different water distribution systems in Greece is presented. The two Water Utilities developed a pressure management strategy. In both cases, Watergems ... -
Educational robotics and down syndrome: Investigating student performance and motivation
(2018)This paper addresses the implementation of a particular didactic scenario using educational robotics in special education and examines its impacts. It reports on a single subject experiment study which involved the design, ... -
Enabling indoor exhibition automated guidance and multimedia content delivery on mobile devices
(2008)Multimedia content delivery is an important issue in assistive guidance systems for exhibition areas. This paper presents an automatic guidance and multimedia content presentation system utilizing location-based services ... -
Energy and communication aware task mapping for MPSoCs
(2018)Minimizing energy consumption and network load is a major challenge for network-on-chip (NoC) based multi-processor systems-on-chip (MPSoCs). Efficient task and core mapping can greatly reduce the overall energy consumption ... -
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 ... -
Forecasting the residential water demand, balancing full water cost pricing and non-revenue water reduction policies
(2014)The paper examines the factors that determine the residential water demand level in the city of Kozani located in the NW part of Greece. Based on an 8-year (2005-12) detailed sample of residential water demand time panel ... -
An integrated urban water management scheme: From source to tap
(2018)Urban water systems have great potential in water and energy saving. A thorough water losses component assessment can reveal this potential and drive utilities into a proper water management scheme towards a more sustainable ... -
Optimization of thermal performance of a building with ground coupled heat pump system
(2006)Component optimization studies during the last twenty years, point to the use of ground source heat pump systems to minimize building heating and cooling costs. Modern computational tools enable building energy simulation ... -
A secure VoIP conference system: Architecture analysis and design issues
(2007)In this paper we present the architectural design of a secure VoIP conference system for mobile devices, which is using the strong security mechanisms of the Z Real Time Transport Protocol (ZRTP). We also provide implementation ... -
Serious gaming to explore the water-energy-food-land-climate nexus with multi-stakeholder participation: The sim4nexus approach
(2018)Water, energy, food, land and climate form a tightly connected nexus in which actions on one sector impact other sectors creating feedbacks and unanticipated consequences. This is especially because at present much scientific ... -
Surface roughness analysis in high speed-dry turning of a tool steel
(2010)High-speed machining is widely applied for the processing of lightweight materials and also structural and tool steels. These materials are intensively used in the aerospace and the automotive industries. The advantages ... -
System design aspects of an independent European AVD-Knowledge base
(2005)It is characteristic that, while AVD communication technology is considered mature, it has not yet been widely integrated into educational settings at a large scale. An important reason for this apparent failure is the ... -
Towards ranking the water-energy-food-land use-climate nexus interlinkages for building a nexus conceptual model with a Heuristic Algorithm
(2019)The concept of the Water-Energy-Food nexus (WEF), as documented by the United Nations Food and Agriculture Organization (FAO), suggests that the three resources are thoroughly interrelated, shaping a complicated web of ... -
Urban water demand forecasting for the Island of skiathos
(2014)We present an analysis of historical water demand data from the utility of Skiathos, Greece and demonstrate suitable demand forecasting methodologies. We apply linear and nonlinear forecasting methods to a three-year time ...
