Abstract:
<p>The elastic structure beneath Greenland is shown by means of S-velocity maps for depths ranging from zero to 350 km, determined by the regionalization and inversion of Rayleigh-wave dispersion. The traces of 50 earthquakes, occurring from 1990 to 2011, have been used to obtain Rayleigh-wave dispersion data. These earthquakes were registered by 21 seismic station located in Greenland and the surrounding area. The dispersion curves were obtained for periods between 5 and 200 s, by digital filtering with a combination of MFT (Multiple Filter Technique) and TVF (Time Variable Filtering).

A partir de catorce sismos de subducción, agrupados en dos trayectorias (una perpendicular y otra paralela a la línea de costa), se calculó un apilado sobre las curvas de dispersión de velocidad de grupo. Estas curvas promedio fueron invertidas usando, por separado, los métodos de algoritmos genéticos y recristalización simulada. Los resultados muestran fuertes diferencias entre ambos modelos corticales, sobre todo, en los parámetros de la capa más somera y en la localización del Moho. Estas diferencias pueden ser explicadas debido a que la primera trayectoria atraviesa el terreno tectonoestra

Las curvas de dispersión continentales se obtuvieron de las velocidades de grupo de ondas de Rayleigh para seis sismos con epicentros en el Atlántico Sur. La inversión sugiere una corteza superior sedimentaria, con velicidades de S de 1.32-2.90 km/s, seguida por un basamento cristalino de 3.06-3.38 km/s. La corteza inferior is transicional (4.02-4.22 km/s) como en otros bordes continentales pasivos. La base de la corteza se encuentra a 36±4 km pero existen valores menores en los perfiles A a C.

Se estudian las excitaciones superficiales que surgen en la superficie de división entre un cristal iónico y una super-red semiconductora en un campo magnético transversal. Se predice 1a existencia de un modo con frecuencias más bajas que la frecuencia ciclotrónica del sistema electrónico. Este modo tiene una velocidad de grupo negativa. Se demuestra que la resonancia entre los polaritones superficiales y los magnetoplasmones lleva a un pequeño desdoblamiento de la frecuencia del poloritón superficial. Se discute además el comportamiento de los puntos iniciales de las curvas de dispersión.

Abstract:
The effect of stress on Lamb wave propagation is relevant to both nondestructive evaluation and structural health monitoring because of changes in received signals due to both the associated strain and the acoustoelastic effect. A homogeneous plate that is initially isotropic becomes anisotropic under biaxial stress, and dispersion of propagating waves becomes directionally dependent. The problem is similar to Lamb wave propagation in an anisotropic plate, except the fourth order tensor in the resulting wave equation does not have the same symmetry as that for the unstressed anisotropic plate,

Abstract:
Over the previous summer I studied mixing of a passive tracer by flow in a straight cylindrical pipe, under the supervision of prof. Bernoff. The mixing process can be thought of as the successive action of advection by the fluid flow and diffusion modeled by random walks. With this method we were able to distinguish three different regimes. For short times, diffusion is more relevant than advection and we observed a Gaussian longitudinal distribution of the concentration. In an intermediate regime, advection by the shear is dominant over longitudinal diffusion and we observed a distinctively

Initially, a sparse two-dimensional dispersion matrix is constructed using sparse wavenumber analysis. Then, B-splines are fitted to non-zero elements of this matrix to establish an initial estimate of the dispersion curve parameters. Th

La modelación de la dispersión de contaminantes es una herramienta indicativa que aporta en la gestión y planificación del territorio, en la realización de estudios de impacto ambiental y en los planes de manejo ambiental. Información relevante: para simular y/o entender la dispersión de las emisiones de contaminantes atmosféricos provenientes de fuentes fijas se han establecido diferentes modelos atmosféricos: caja, modelo gaussiano, euleriano, lagrangiano, tipo “puff”, receptor y hasta estadísticos. En el caso de los modelos gaussianos se busca describir la dispersión en la horizontal y en l

Abstract:
This work uses on-line monitoring of turbidity to ascertain the temperature impact on the mixing performance of kneading blocks with different geometries. For this purpose, one of the barrel segments of the extruder was modified to incorporate four sampling devices and a slit die containing optical windows. The experiments consisted in reaching steady extrusion and then adding a small amount of tracer. Upon opening each sampling device, material was laterally detoured from the local screw channel and its turbidity were measured by the optical detector. Residence time distribution (RTD) curves

Abstract:
The study reports on circumferential guided wave inspection potential and propagation in a tar coated pipe. A computer code based on a matrix technique was developed to calculate the circumferential guided wave dispersion curves and wave structures in a viscoelastic multi-layered pipe. Experiments utilizing the SwRI Magnetostrictive ILI inspection technique were conducted under different coating conditions. There was a favorable agreement with theory. This study provides an insight into attenuation effect, ways to improve propagation distance, and a baseline for further studies on wave scatter

Abstract:
This report describes activity conducted in several lines of research associated with field-scale water and solute processes. A major effort was put forth developing a stochastic continuum analysis for an important class of problems involving flow of reactive and non reactive chemicals under steady unsaturated flow. The field-scale velocity covariance tensor has been derived from local soil properties and their variability, producing a large-scale description of the medium that embodies all of the local variability in a statistical sense. Special cases of anisotropic medium properties not alig
