An algorithm for discretization of real value attributes based on interval similarity
(Journal article; Peer reviewed, 2013)Discretization algorithm for real value attributes is of very important uses in many areas such as intelligence and machine learning. The algorithms related to Chi2 algorithm ( includes modified Chi2 algorithm and extended ... -
Convective instability in a horizontal porous channel with permeable and conducting side boundaries
(Journal article; Peer reviewed, 2013)The stability analysis of the motionless state of a horizontal porous channel with rectangular cross-section and saturated by a fluid is developed. The heating from below is modelled by a uniform flux, while the top wall ... -
Convective Roll Instabilities of Vertical Throughflow with Viscous Dissipation in a Horizontal Porous Layer
(Journal article; Peer reviewed, 2010)The vertical throughflow with viscous dissipation in a horizontal porous layer is studied. The horizontal plane boundaries are assumed to be isothermal with unequal temperatures and bottom heating. A basic stationary ... -
Dynamics of a single species in a fluctuating environment under periodic yield harvesting
(Journal article; Peer reviewed, 2013)We discuss the effect of a periodic yield harvesting on a single species population whose dynamics in a fluctuating environment is described by the logistic differential equation with periodic coefficients. This problem ... -
Linear instability of mixed convection of cold water in a porous layer induced by viscous dissipation
(Journal article; Peer reviewed, 2009)An analysis of linear stability of the stationary laminar Darcy flow in a horizontal porous layer is performed. The porous layer is saturated with cold water. The upper plane boundary is assumed to be subject to heat ... -
Onset of convection in a porous rectangular channel with external heat transfer to upper and lower fluid environments
(Journal article; Peer reviewed, 2012)The conditions for the onset of convection in a horizontal rectangular channel filled with a fluid saturated porous medium are studied. The vertical sidewalls are assumed to be impermeable and adiabatic. The horizontal ... -
Stability of Flow with Viscous Dissipation in a Horizontal Porous Layer with an Open Boundary Having a Prescribed Temperature Gradient
(Journal article; Peer reviewed, 2010)A buoyancy-induced stationary flow with viscous dissipation in a horizontal porous layer is investigated. The lower boundary surface is impermeable and subject to a uniform heat flux. The upper open boundary has a prescribed, ... -
Viscous dissipation and thermoconvective instabilities in a horizontal porous channel heated from below
(Journal article; Peer reviewed, 2010)A linear stability analysis of the basic uniform flow in a horizontal porous channel with a rectangular cross section is carried out. The thermal boundary conditions at the impermeable channel walls are: uniform incoming ...
