Fisheye camera modeling for human segmentation refinement in indoor videos
(2013)In this paper, we concentrate on refining the results of segmenting human presence from indoors videos acquired by a fisheye camera, using a 3D mathematical model of the camera. The model has been calibrated according to ... -
Gas flow in a grooved channel due to pressure and temperature gradients
(2006)The flow of a gas in a grooved nano or micro channel, due to the imposed pressure and temperature gradients in the longitudinal direction, is investigated via a kinetic approach. The solution is valid in the whole range ... -
Groundwater modeling and management in a complex lake-aquifer system
(2007)In this paper, the hydrogeologic analysis and the development of a numerical model for the simulation of a complex system of aquifers in Northern Greece are presented. The study area faces a severe environmental danger as ... -

Lateral loading of internally pressurized steel pipes
(2005)The paper examines the denting response of tubular members and pipes subjected to lateral (transverse) quasi-static loading, in the presence of internal pressure. Tubes are modeled with nonlinear shell finite elements, and ... -
Maximum lifetime routing in wireless sensor networks
(2004)A routing problem in static wireless ad hoc networks is considered as it arises in a rapidly deployed, sensor based, monitoring system known as the wireless sensor network. Information obtained by the monitoring nodes needs ... -
The McCormack model: Channel flow of a binary gas mixture driven by temperature, pressure and density gradients
(2004)An analytical version of the discrete-ordinates method (the ADO method) is used to establish concise and particularly accurate solutions to the problems of Poiseuille flow, thermal-creep flow and diffusion flow for a binary ... -
Mechanical behavior of buried steel pipelines crossing strike-slip seismic faults
(2011)The present paper investigates the mechanical behaviour of buried steel pipelines, crossing active strike-slip tectonic faults. The fault plane is vertical and perpendicular to the pipeline axis. The interacting soil-pipeline ... -
The migration of the UTHBAL hydrologic model into OpenMI
(2008)This paper deals with the implementation and the migration into OpenMI of a monthly conceptual hydrological model, called UTHBAL. The model has been developed by Loukas et al. [2003, 2007] and now is implemented under the ... -
Modeling of hydrocarbon trap systems
(2000)Hydrocarbon traps for gasoline engines are promising candidates for cold start emission control, provided that their design is based on a "systems approach". In this paper, an existing CAE methodology for exhaust after-treatment ... -
