Natural convection in semi trapezoidal enclosure

, 2006
Numerical analysis approach for natural convection in semi trapezoidal shaped cavity is investigated by applying constant heat flux from the top. Buoyancy consideration of Boussinesq approximation noted valid for this incompressible problem of ideal gas ...

Evaluation of Third‐Order Motion‐Compensated Cardiac Diffusion Tensor Imaging Across Cardiac Phases Using an Ultra‐High‐Performance Clinical Scanner

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate a third‐order motion‐compensated spin echo (M3‐MCSE) sequence at multiple cardiac phases on a clinical 3 T MRI scanner with ultra‐high performance (UHP) gradients (200 mT/m), compared with stimulated echo acquisition mode (STEAM) and second‐order MCSE (M2‐MCSE) for cardiac diffusion tensor imaging (cDTI).

On the approximation of compact fuzzy sets

, 2015
This paper suggests an approximation for a compact fuzzy set by a sequence of Lipschitz fuzzy sets. This approximation method involves the construction of Lipschitz fuzzy sets using the sup-min convolution of a compact fuzzy set with a fuzzy zero ...

A Modified Balanced Steady State Free Precession Sequence for Overhauser Magnetic Resonance Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Low‐ and ultralow‐field magnetic resonance imaging (ULF MRI) have inherently low signal‐to‐noise ratio (SNR) by design. Overhauser dynamic nuclear polarization (ODNP) stands out as an effective solution for continuous signal enhancement.

Stability Analysis and Finite Difference Approximations for a Damped Wave Equation with Distributed Delay

Mathematics
This paper presents a fully implicit finite difference scheme for the numerical approximation of a wave equation featuring strong damping and a distributed delay term. The discretization employs second-order accurate approximations in both time and space.

On the nearest parametric approximation of a fuzzy number

, 2008
Many nearest parametric approximation methods of fuzzy sets are proposed in the literature. It is clear that the specific approximations may lead to the loss of information about fuzziness.
