Analyzing the location decisions of agro-industrial investments in Greece
(2015)This article examines empirically the factors determining the agro-industrial investments in Greece and their impact on tourism development. Firstly, the determinants influencing the spatial configuration, the socioeconomic ... -
A comparison of distributed spatial data management systems for processing distance join queries
(2017)Due to the ubiquitous use of spatial data applications and the large amounts of spatial data that these applications generate, the processing of large-scale distance joins in distributed systems is becoming increasingly ... -
Dynamic Multiple Vehicle Routing under Energy Capacity Constraints
(2020)The multiple vehicle routing problem (mVRP) concerns the scheduling of multiple vehicles so as to visit some locations of interest. We study a dynamic version of mVRP where the travel costs are not a priori known and may ... -
Dynamic Vehicle Routing Under Uncertain Energy Consumption and Energy Gain Opportunities
(2021)The amount of energy that needs to be spent by a vehicle to travel between different locations, and the amount of energy that can be regained at certain locations, may not always be known in advance with certainty. In this ... -
Dynamic vehicle routing under uncertain travel costs and refueling opportunities
(2019)We study the vehicle routing problem for a system where there is some uncertainty regarding both the cost of travel and the refueling opportunities. Travel cost stands for the energy spent by the vehicle to move between ... -
Efficient distance join query processing in distributed spatial data management systems
(2020)Due to the ubiquitous use of spatial data applications and the large amounts of such data these applications use, the processing of large-scale distance joins in distributed systems is becoming increasingly popular. Distance ... -
Exploring the Random Location Problem Inside a Truncated Conic Shape: Application in UAV Communications
(2022)More often than not, transmitters (Txs) in wireless networks operate using directional radiation patterns where the main radiation lobe creates a three-dimensional conic-shaped volume. In this context, any receiver (Rx) ... -
Fast Heuristics for Mixed Fleet Capacitated Multiple TSP with Applications to Location Based Games and Drone Assisted Transportation
(2021)The Travelling Salesman Problem (TSP) is one of the most known problems in combinatorics and consists of finding a route so that a salesman visits all destination points exactly once with minimum cost. Applications of the ... -
Gathering of robots in a grid with mobile faults
(2019)The gathering of two or more agents in a graph is an important problem in the area of distributed computing and has been extensively studied especially for the fault free scenario. In this paper we consider the mobile ... -
Geography as a locational determinant of foreign direct investments in tourism and transport in Greece: a comparison with domestic investments
(2022)It is widely known that inward foreign direct investments contribute to the economic growth of a host country. Each country attracts foreign investments by shaping and improving its location advantages, such as geography-driven ... -
GeoMakeIt!: A Platform for Developing Location Based Games
(2020)Location based or pervasive games are played outdoors from users with GPS enabled smartphone devices and involve physical visits of various geographical locations by the player. The fact that the playing area combines both ... -
A hybrid numerical-experimental assessment of railway ground vibration in urban area
(2018)A common source of railway-induced ground vibrations is local defects such as rail joints, switches, and turnouts which cause large amplitude excitations at isolated locations along the track. Moreover, the distance between ... -
Hydrogen storage station location selection in sustainable freight transportation via intuitionistic hesitant decision support system
(2022)Increasingly fierce competition in energy industry for alternative fuels has raised demand for fuel storage stations to be one of the pivots towards sustainable urban freight transportation. For zero-emission hydrogen-powered ... -
Location Planning of Small Consolidation Centers in the City of Volos
(2021)As urbanization increases by the years the needs of the society, in terms of quantity of urban freight deliveries, become more demanding. Urban freight transport and goods distribution become the main challenges that a ... -
Mobile vehicle emission inspection service optimization: a flow intercepting location model and application
(2020)Emission screening and control for motorized traffic is mandatory in most countries worldwide. However, there may be cases that periodic inspections in permanent establishments may be inefficient and fail to enforce emission ... -
Newly Developed Seismic Resilient Steel Pipe Joint Safeguards: Pipeline Structural Integrity during Severe Geohazard Events
(2020)The mechanical performance of lap welded joints is essential for safeguarding the structural integrity of steel water pipelines, after a severe earthquake or other geohazard loadings. Over the past 4 years, an extensive ... -
Optimal number and location of watchtowers for immediate detection of forest fires in a small island
(2017)A crucial factor for prevention and immediate confrontation of destructive fires and their socioeconomic and environmental consequences constitutes the early detection and spatial localization of fire ignitions, so that ... -
Optimal sensor placement for parameter estimation and virtual sensing of strains on an offshore wind turbine considering sensor installation cost
(2022)This paper proposes an optimal sensor placement (OSP) framework for parameter estimation, virtual sensing, and condition monitoring using information theory. The framework uses a Bayesian OSP method combined with modal ... -
Optimal sensor placement for response predictions using local and global methods
(2020)A Bayesian framework for model-based optimal sensor placement for response predictions is presented. Our interest lies in determining the parameters of the model in order to make predictions about a particular response ... -
PET Counting Response Variability Depending on Tumor Location, Activity, and Patient Obesity: A Feasibility Study of Solitary Pulmonary Nodule Using Monte Carlo
(2019)We aim to investigate the counting response variations of positron emission tomography (PET) scanners with different detector configurations in the presence of solitary pulmonary nodule (SPN). Using experimentally validated ...
