3-D simulations of flows in the reconstituted lake Karla, Thessaly, Greece
(2010)We report on three-dimensional flow simulations carried out in order to describe the dominant water current patterns in the reconstituted lake Karla. The flow is considered to be generated mainly by wind shear while the ... -
Comparison of ARIMA and Transfer Function (TF) models in Water Temperature simulation in dam - Lake Thesaurus, eastern Macedonia, Greece
(2010)In the present work, two modelling and forecasting techniques were evaluated on the basis of: a) their efficiency to forecast and b) their ability to utilize auxiliary environmental information: ARIMA and Transfer Function ... -
Effect of high pressure on temperature dependences of the resistivity in the ab-plane of Y0.77Pr0.23Ba2Cu3O7-δ single crystals
(2022)In the present work, we investigated the influence of high hydrostatic pressure up to 11 kbar on the conductivity in the basal ab-plane of medium-doped with praseodymium (x≈0.23) single-crystal Y1-xPrxBa2Cu3O7-δ samples. ... -
Evaluating the performance level of a water distribution network under unbalanced operating conditions - The case of Kos Town (GR)
(2010)The need for a common international terminology is growing the last few years regarding the performance evaluation of urban water distribution systems, due to the wide diversity of definitions used across the word (even ... -
Finite element modeling of porous solid propellants
(2005)The effect of porosity on the constitutive response of a linearly viscoelastic solid that obeys a constitutive law of the standard differential form is investigated under small strain deformation conditions. It is demonstrated ... -
Impact of temperature and pressure on phase separation in the basal plane of Y0.77Pr0.23Ba2Cu3O7-δsingle crystals
(2022)Here, we study the impact of high hydrostatic pressure (up to 11 kbar) on the conductivity in the basal ab plane of Y0.77Pr0.23Ba2Cu3O7-δ single crystals. Conversely to YBa2Cu3O7-δ single crystals, it was found that high ... -
Inactivation of Listeria monocytogenes in raw and hot smoked trout fillets by high hydrostatic pressure processing combined with liquid smoke and freezing
(2020)High hydrostatic pressure (HHP; 200 MPa for 15 min), liquid smoke (0.50%, v/v) and freezing (−80 °C, overnight) was used to eliminate Listeria monocytogenes in BHI broth, raw and smoked trout. The bactericidal effect of ... -
Molecular dynamics simulations of ion separation in nano-channel water flows using an electric field
(2019)Removal of undesired substances from water is a field of investigation recently focused at the nanoscale. Towards this direction, molecular dynamics simulations are conducted in this paper to investigate unwanted ion removal ... -
Proteus: An architectural synthesis tool based on the stream programming paradigm
(2009)The problem of automatically generating hardware modules from a high level representation of an application has been at the forefront of EDA research in the last few years. Such an EDA methodology would potentially enable ... -
Spreading of buoyant jets and fountains in a calm, linearly density-stratified fluid
(2010)Round turbulent buoyant jets and fountains issuing vertically into linearly densitystratified calm ambient were investigated experimentally. The terminal (steady state) height of rise and the elevation of horizontal spreading ... -
Transition from permeable to impermeable beds and vice versa in open channels: Effects on the velocity distribution of turbulent flow
(2014)This study investigates the impact of permeable to impermeable (and vice versa) bed transition on the velocity distribution of turbulent flow in an open channel. This experimental investigation is based on the 2D Particle ... -
Water Purification in Micromagnetofluidic Devices: Mixing in MHD Micromixers
(2016)This contribution addresses a possible solution for water purification from heavy metals by magnetic nanoparticles in microfluidic water flow systems. In this technique, the most important component is the micromixer while ...
