The geometrical frustration in the magnetic pyrochlore oxides causes interesting properties at low temperatures in these materials. Therefore, we studied two challenging materials, Er2Ti2O7 and Tb2Ti2O7, using an ab intio method, based on Density Functional Theory (DFT). To take into account the f electrons coulomb interactions correctly, we employed DFT+U, a Hubbard method correction. As spin-...

Microbubble generators are of considerable importance to a range scientific fields from use in aquaculture and engineering medical applications. This is due the fact amount sea life water proportional oxygen it. In this paper, experimental measurements computational Fluid Dynamics (CFD) simulation performed for three flow rates with different air rates. The data presented paper used validate CF...

In this paper, a geophysical strategy based on the recently proposed Manta-Ray Foraging (MRF) Optimization algorithm is adapted and presented for blind computation of depth/shape defining parameters from magnetic anomalies due to buried geo-bodies. The model deciphered are coefficient amplitude (K), structure’s origin (x 0 ), depth (z), magnetization angle (?), shape factor (q). After detailed ...

RECENT advances in microwave computer-aided design (CAD) technology, the availability of powerful PC’s, workstations, and massively parallel systems, suggest the feasibility of interfacing electromagnetic (EM) simulations into optimization systems or CAD frameworks for direct application of powerful optimizers. With fast, robust, commercial EM simulators increasingly available, microwave engine...

In medical image analysis, geometrical deformations are used to model intersubject variability. In orthopaedic applications, the geometrical variability is usually observable across anatomical scales. For instance, anatomical differences between mandible bones of different patients can be found on a coarse scale, between the entire left or right side, or on a fine scale, between teeth. Each lev...
