Abstract: Based on the concept of constitutive relation error along with residual of both origin and dual problems, a goal-oriented error estimation method with extended degrees of freedom was developed. It leads to the high quality local error bounds in the problem of direct-solution steady-state dynamic ana...
Abstract: The moment Liapunov exponent of a co-dimension two bifurcation system was evaluated, which was on a three-dimensional central manifold and was subjected to a parametric excitation by a bounded noise. Based on the theory of the stochastic dynamics, the eigenvalue problem governing the moment Liapunov...
Abstract: Along with the deepening of research on physics and technology,dynamics of fractional order nonlinear systems and synchronization of fractional order chaotic systems focus strong attention on itself. The dynamic behavior including chaotic properties of fractional order Duffing systems was extensivel...
Abstract: Spacecrafts with the pure gravity environment were of great significance in precision navigation, gravity field measurement for celestial bodies and basic physics experiments. Radiometer effect was one of the important interfering factors on proof mass in the purely gravitational orbit. For gravity ...
Abstract: The MHD convective flow and heat transfer of an incompressible viscous nanofluid past a semi infinite vertical stretching sheet in the presence of thermal stratification were examined. The partial differential equations governing the problem under consideration were transformed by a special form of ...
Abstract: A numerical study was performed to examine the heat transfer characteristics of natural convection past a vertical cone under the combined effects of magnetic field and thermal radiation. The surface of the cone was subjected to a variable surface heat flux. The fluid considered was a gray, absorbin...
Abstract: A two-level stabilized finite element method for the Stokes eigenvalue problem based on local Gauss integration was considered. The method involved solving a Stokes eigenvalue problem on a coarse mesh with mesh size H and a Stokes problem on a fine mesh with mesh size h=O(H2), which can still mainta...
Abstract: The magnetohydrodynamic (MHD) stagnation point flow of micropolar fluid towards a heated shrinking surface was analyzed. The effects of viscous dissipation and internal heat generation/absorption were taken into account. Two explicit cases of prescribed surface temperature (PST) and prescribed heat ...
Abstract: A problem was motivated towards studying heat and mass transfer in the unsteady MHD flow of blood through a porous vessel, when the lumen of the vessel had turned into a porous structure. Consideration of time-dependent permeability and oscillatory suction velocity had been made. The problem was sol...
Abstract: The influence of thermal radiation on the problem of mixed convection thin film flow and heat transfer of a micropolar fluid past a moving infinite vertical porous flat plate with slip velocity was dealt with. The fluid viscosity and the thermal conductivity were assumed to vary as a function of tem...
