Crystal structure, electron density and chemical bonding in inorganic compounds studied by the Electric Field Gradient
… electron density is the electric field gradient (EFG). The EFG reflects local structural symmetry properties of the charge distribution surrounding a nucleus: the EFG is nonzero if the density deviates from cubic symmetry and therefore generates an inhomogeneous electric field at the nucleus. …

Proper orthogonal decomposition with interpolation-based real-time modelling of the heart
… using the Element-free Galerkin method (EFG) and then project a selected subset of these solutions to a low dimensional space. Using the Moving Least Square method (MLS), an interpolation is carried out for the problem-at-hand, before the resulting coefficients are projected back to the …

Moessbauer Studies on Partially Oriented Samples of Carbon Monoxymyoglobin and Photodissociated Carbon Monoxymyoglobin
… interaction with the electric field gradient (EFG) at the ('57)Fe nucleus. The photo-produced partial orientation affects the intensity ratio R of the two lines; measurements of R versus the fraction MbCO remaining allows the determination of the asymmetry parameter (eta) of the EFG and the …

NOVEL NUMERICAL PROCEDURES FOR LIMIT ANALYSIS OF STRUCTURES: MESH-FREE METHODS AND MATHEMATICAL PROGRAMMING
… In this research, the Element-Free Galerkin (EFG) discretisation strategy is used to approximate the displacement and moment fields in plate and slab problems, and second-order cone programming (SOCP) is used to solve the resulting discretised formulations. A numerical procedure using the EFG …

Cohomological invariants for infinite groups
… classifying space for proper actions EFG. A large part of the thesis is motivated by an old conjecture of Kropholler and Mislin claiming that every H1F-group G admits a finite-dimensional model for EFG. The natural choice for studying algebraically H1F-groups is F-cohomology. This is a …

Gender Variation in CROTON CALIFORNICUS (EUPHORBIACEAE)
… by calculating the Estimated Floral Gender (EFG) which varied from 1.00 (female) to 0.00 (male). The distribution of the EFG was highly skewed towards maleness. Monoecious individuals were then categorized by their EFG values as phenotypic male, quasi male, equisexual, quasi female, and …

It was observed that the correlation between color and structure of the newly prepared hydrocarbons follows the principles of annelation. When the ultraviolet and visible spectra peak frequencies were compared it was found that the …
