This paper presents a novel computational framework based on dynamic spherical volumetric simplex splines for simulation of genuszero real-world objects. In this framework, we first develop an accurate and efficient algorithm to reconstruct the high-fidelity digital model of a real-world object with spherical volumetric simplex splines which can represent with accuracy geometric, material, and ...

left atrial (la) distension has been demonstrated to be linked with aortic stiffness in different patient populations. three-dimensional (3d) speckle-tracking echocardiography (ste) seems to be a promising tool for volumetric and functional evaluation of the la. the aim of the present study was to determine whether correlations exist between 3dste-derived la volume-based and strain parameter...

A method for the fast generation of solid molecular surfaces is described. Based on a three dimensional grid, a template driven procedure generates the so called “contact surface“, also known as Connolly surface. The main advantages of this method are its good perfarmance and that it directly generates continuously tessellated

Homogeneous stable suspensions obtained by dispersing dry TiO2 nanoparticles in pure ethylene glycol were prepared and studied. Two types of nanocrystalline structure were analyzed, namely anatase and rutile phases, which have been characterized by scanning electron microscopy. The rheological behavior was determined for both nanofluids at nanoparticle mass concentrations up to 25%, including f...

We consider “swept regions”Ω and “swept hypersurfaces”B in R n+1 (and especially R) which are a disjoint union of subspaces Ωt = Ω∩Πt or Bt = B∩Πt obtained from a varying family of affine subspaces {Πt : t ∈ Γ}. We concentrate on the case where Ω and B are obtained from a skeletal structure (M, U). This generalizes the Blum medial axis M of a region Ω, which consists of the centers of interior ...

The need for accurate modeling of fluid-mineral processes over wide ranges of temperature, pressure and composition highlighted considerable uncertainties of available property data and equations of state, even for the CO2 + H2O binary system. In particular, the solubility, activity, and ionic dissociation equilibrium data for the CO2-rich phase, which are essential for understanding dissolutio...

IN T RODUC T ION Synthesis and characterization of cyclometalated iridium (III) complexes in organic light emitting display (OLED) applications is of great interest, as these complexes display high emission quantum yields and can be readily colortuned through systematic modification of the ligands using facile syntheses. Depending on the types of ligands surrounding the central iridium atom, th...

Most models used in land surface hydrology, vadose zone hydrology, and hydro-climatology require an accurate representation of soil thermal properties (soil thermal conductivity and volumetric heat capacity). Various empirical relations have been suggested to estimate soil thermal properties. However, they require many input parameters such as soil texture, mineralogical composition, porosity a...
