In this paper we exploit the effectiveness of bioinformatics tools to deal with 3D shape matching. The key idea is to transform the shape into a biological sequence and take advantage of bioinformatics tools for sequence alignment to improve shape matching. In order to extract a reliable ordering of mesh vertices we employ the spectral-based sequencing method derived from the well known Fiedler...

Solid-liquid extraction is carried out from vegetable substrates in industrial continuous counter-current extractor. A batch study was conducted to obtain the extraction kinetic and the bulk phase saturation. An extraction model is proposed and compared with experimental data. This model is based on the general diffusion model including a shape factor of solid particle. A methodology for the ba...

We present a novel extension to shape grammars, in which the generated shapes are voxelized. This allows easy Boolean geometry operations on the shapes, and detailing of generated models at a sub-shape level, both of which are extremely difficult to do in conventional shape grammar implementations. We outline a four step algorithm for using these extensions, discuss a number of optional enhance...

We present model calculations for the inelastic cross sections of electron collisions with tetrahedral molecules XH4 ~X5C, Si, Ge! when only the molecular ‘‘breathing’’ mode, n1 , is being excited. The collision energy range is well above the excited thresholds and up to 12 eV, where the adiabatic approximation for the inelastic T matrix is expected to hold. The results show the efficiency of t...

Cylindrical microparticle transport and deposition from electrokinetic microflow in a 90 degree bend have been numerically simulated. Under the effect of dielectrohporetic force, gravity and stokes force, it’s found that microparticles with larger size deposit on the lower region of the bend’s outer wall. An exponential curve of deposition efficiency versus the product of stokes number and shap...

This paper presents a spline approximation method for the representation of a large set of points. The representation should be smooth with preserving important shape characteristics given by the points. Because of a large size of the set, the standard spline interpolation cannot be used. The proposed method is based on a least squares minimization of the distances of the points from the spline...

Use of dual-wavelength radar, with properly chosen wavelengths, will significantly lessen the ambiguities in the retrieval of microphysical properties of hydrometeors. In this paper, a dual-wavelength algorithm is described to estimate the characteristic parameters of the snow size distributions. An analysis of the computational results, made at X and Ka bands (T-39 airborne radar) and at S and...

The objective of this work was to dry sewage sludge using a fry-drying process. The frying experiments were carried out in commercial fryers modified by adding thermocouples to the setup. During frying, typical drying curves were obtained and it was verified that, in relation to the parameters: oil temperature, oil type and shape of the sample, the shape factor the most effect on the drying rat...

A method based on an image analysis procedure was developed to calculate the shape and surface tension of pendant droplets hanging down in air from the tip of a syringe. In contrast to most existing methods, a numerical solution of the YoungLaplace equation of capillarity for the calculation of the drop contour is not required. Apart from local gravity and densities of liquid and fluid phases, ...

Vision is the most advanced of our senses, so it is not surprising that images contribute important role in human perception. This is analogous to machine vision such as shape recognition application which is important field nowadays. This paper introduces a new approach for recognizing twodimensional shapes in an image, and also recognizes the shapes type. The algorithm recognizes all the know...
