Correlazioni tra le velocità ultrasoniche e le caratteristiche petrografiche in ceramiche archeologiche: un primo approccio metodologico

2010

L’analisi delle velocità degli ultrasuoni permette di investigare i caratteri tessiturali e strutturali e di individuare la presenza di eventuali difetti localizzati all’interno del campione. La loro diffusione negli studi archeometrici è legata alla non distruttività e alla possibilità di fornire risultati accurati in tempo reale. In questo lavoro sono state effettuate numerose analisi petrografiche in sezione sottile e misure di velocità di propagazione degli ultrasuoni su reperti ceramici di interesse archeologico. In particolare sono stati selezionati ed analizzati ceramiche preistoriche ed anfore da trasporto del V-IV sec. a.C., caratterizzati da differente granulometria, composizione …

Synthesis, crystal structure and molecular conformation of the tBuCO-D,L-Ala-Δz-Phe-NhiPr α,β-unsaturated dipeptide

2009

The crystal structure of the tBuCO-D,L-Ala-delta Z-Phe-NHiPr dipeptide has been solved by X-ray diffraction. The peptide crystallizes in monoclinic space group P2(1)/c with a = 13.445 (3) A, b = 35.088 (4) A, c = 14.755 (3) A, beta = 116.73 (1) degree, Z = 12 and dc = 1.151 g.cm-3. The three independent molecules per asymmetric unit accommodate a beta II-folded conformation, but only one of them contains the typical i + 3----i interaction characterizing a beta-turn. In the other two molecules, the N...O distance exceeds 3.2 A, a value generally considered the upper limit for hydrogen bonds in peptides. In solution, the beta II-turn conformation is largely predominant.

Introducción al diseño de sistemas integrados

2014

Material docente perteneciente a la asignatura Sistemas Integrados que se imparte en el Máster Oficial de Ingeniería Electrónica de la ETSE-UV. Los Sistemas Digitales Avanzados son aquellos en los que el núcleo del sistema es uno de los dispositivos de computación usual. En este bloque se realiza un estudio del estado del arte de este tipo de dispositivos y se presentan las tres metodologías empleadas para su diseño: software, hardware y codiseño. Se realiza una explicación de la arquitectura de un Sistema Empotrado "software" basado en MicroBlaze tanto desde el punto de vista teórico como práctico. Para esto último, se incluye una práctica guiada en la que se describen los pasos a seguir p…

158. Velocity estimation of high-concentrated flows: sensitivity analysis with main parameters included in the Bagnold equation

2017

As it is known, the propagation of debris flow causes huge territorial changes and damages in short times. The motion of debris flow is determined by gravity and it especially occurs in steep mountainous areas. Debris flow velocity is an important factor which influences the impact forces and runup. In this context, in the present work attention is restricted to Bagnolds Equation with the specific aim to assess the impact of the aforementioned assumptions in flow velocity estimation.

Beta-spectrum shapes of forbidden β decays

2018

The neutrinoless [Formula: see text] decay of atomic nuclei continues to attract fervent interest due to its potential to confirm the possible Majorana nature of the neutrino, and thus the nonconservation of the lepton number. At the same time, the direct dark matter experiments are looking for weakly interacting massive particles (WIMPs) through their scattering on nuclei. The neutrino-oscillation experiments on reactor antineutrinos base their analyses on speculations of [Formula: see text]-spectrum shapes of nuclear decays, thus leading to the notorious “reactor antineutrino anomaly.” In all these experimental efforts, one encounters the problem of [Formula: see text]-spectrum shapes of…

Human Activity Signatures Captured under Different Directions Using SISO and MIMO Radar Systems

2022

In this paper, we highlight and resolve the shortcomings of single-input single-output (SISO) millimeter wave (mm-Wave) radar systems for human activity recognition (HAR). A 2×2 distributed multiple-input multiple-output (MIMO) radar framework is presented to capture human activity signatures under realistic conditions in indoor environments. We propose to distribute the two pairs of collocated transmitter–receiver antennas in order to illuminate the indoor environment from different perspectives. For the proposed MIMO system, we measure the time-variant (TV) radial velocity distribution and TV mean radial velocity to observe the signatures of human activities. We deploy the Anc…

Evaluación cardiometabólica y adrenérgica en el sujeto obeso sano joven

2021

ANTECEDENTES: La obesidad se define como un exceso de peso del individuo, entendiendo como tal el exceso de contenido graso en el cuerpo. Actualmente la OMS sitúa a la obesidad como la epidemia del siglo XXI. La obesidad incrementa el riesgo de diabetes, hipertensión, enfermedad coronaria, ictus y ciertos tipos de cáncer. Independientemente del mecanismo primario responsable de la obesidad existen un serie de mecanismos que se encuentran interrelacionados y que llevan a la aparición de: I) Alteraciones metabólicas del metabolismo hidrocarbonado y lipídico, con el consiguiente incremento del riesgo de desarrollar diabetes mellitus tipo 2, II) alteraciones precoces en el sistema cardiovascula…

Reti sismiche urbane per monitoraggio sismico monitoraggio strutturale ed allerta precoce

2021

In questa tesi, viene effettuato un analisi preliminare in cui si mette in evidenza come l'italia sia un paese a rischio sismico, poichè possiede molti centri storici con strutture non progettate per eventi sismici di media entità. Si è prestato molta attenzione su quante vite umane vengono salvate dopo un terremoto catastrofico. L'analisi fa emergere come, è importante essere tempestivi nell'estrarre le persone rimaste sotto le macerie, poichè la percentuale di persone estratte vive si mantiene alta solo entro le 48 ore dall'evento. Dopo 96 ore questa percentule si attesta a 0. In eventi passati spesso i soccorsi sono arrivati con giorni di ritardo nelle zone più devastate. L'obbiettivo ch…
