Intelligent Cloud Storage Management for Layered Tiers
2018
Today, the cloud offers a large array of possibilities for storage, with this flexibility comes also complexity. This complexity stems from the variety of storage mediums, such as, blob storage or NoSQL tables, and also from the different cost tiers within these systems. A strategic thinking to navigate this complex cloud storage landscape is important, not only for cost saving but also for prioritizing information, this prioritization has wider implications in other domains such as the Big Data realm, especially for governance and efficiency. In this paper we propose a strategy centered around probabilistic graphical model (PGM), this heuristic oriented management and organizational strate…
Large Eddy Simulations of Rough Turbulent Channel Flows Bounded by Irregular Roughness: Advances Toward a Universal Roughness Correlation
2020
The downward shift of the mean velocity profile in the logarithmic region, known as roughness function, $$\Delta U^+$$ , is the major macroscopic effect of roughness in wall bounded flows. This speed decrease, which is strictly linked to the friction Reynolds number and the geometrical properties which define the roughness pattern such as roughness height, density, shape parameters, has been deeply investigated in the past decades. Among the geometrical parameters, the effective slope (ES) seems to be suitable to estimate the roughness function at fixed friction Reynolds number, Re $$_{\tau }$$ . In the present work, the effects of several geometrical parameters on the roughness function, i…
Electrodeposition of CeO2 and Co-Doped CeO2 Nanotubes by Cyclic Anodization in Porous Alumina Membranes
2013
An anodic electrodeposition process is proposed to prepare CeO2 and Co-doped CeO2 nanotubes. Anodic alumina membrane is used as template and linear sweep voltammetry is employed to allow the formation of nanotubes without alumina dissolution. SEM micrographs showed large arrays of well defined and aligned NTs, which resulted to be crystalline soon after deposition according to XRD diffraction patterns and Raman Spectroscopy.
FUTURE IS BACK
2017
«Trent'anni fa, un piano per il futuro di New York sarebbe apparso futile» Michael R. Bloomberg, sindaco di New York, che ha introdotto nel 2007 la relazione sul futuro della città per il 2030, PlaNYC, oppose la città degli anni 1970, «interamente concentrata sulla risoluzione di crisi immediate», alla città di quegli anni, «più forte che mai»: consapevole di aver ritrovato il desiderio del futuro. La data dell'11 settembre non è percepita come un presagio della fine della supremazia americana, è un evento superato - Future is back ! Questo ritorno nel futuro è immaginato da tutte le metropoli preoccupate di inserirsi nel mercato dell'attrattività3. Trent'anni dopo la fine del progresso, l'…
Search for neutralino pair production at root s = 189 GeV
2001
A search for pair-production of neutralinos at a LEP centre-of-mass energy of 189 GeV gave no evidence for a signal. This limits the neutralino production cross-section and excludes regions in the parameter space of the Minimal Supersymmetric Standard Model (MSSM).
Education and working life: VET adults' problem-solving skills in technology-rich environments
2015
The rapidly-advancing technological landscape in the European workplace is challenging adults' problem-solving skills. Workers with vocational education and training need flexible abilities to solve problems in technology-rich work settings. This study builds on Finnish PIAAC data to understand adults' (N?=?4503) skills for solving problems in technology-rich environments. The results indicate the critical issue that more than two thirds of adults with vocational education and training have weak skills or lack the skills in solving problems in technology-rich environments and that more than one fifth of these adults are at risk. Furthermore, this study indicates that the likelihood of havin…
Genome-wide homozygosity and risk of four non-Hodgkin lymphoma subtypes
2021
Aim: Recessive genetic variation is thought to play a role in non-Hodgkin lymphoma (NHL) etiology. Runs of homozygosity (ROH), defined based on long, continuous segments of homozygous SNPs, can be used to estimate both measured and unmeasured recessive genetic variation. We sought to examine genome-wide homozygosity and NHL risk.Methods: We used data from eight genome-wide association studies of four common NHL subtypes: 3061 chronic lymphocytic leukemia (CLL), 3814 diffuse large B-cell lymphoma (DLBCL), 2784 follicular lymphoma (FL), and 808 marginal zone lymphoma (MZL) cases, as well as 9374 controls. We examined the effect of homozygous variation on risk by: (1) estimating the fraction o…
The “Gentle Law” of Large Numbers: Stifter’s Urban Meteorology

Avaluació continua con Goodle-GMS a més de 800 alumnes en Enginyeria Química.
2014
L'objectiu d'aquesta experiència ha estat la d'establir un sistema d'avaluació contínua en assignatures amb gran quantitat d'alumnes de manera que no suposin un excessiu treball per al docent, que permeti generar una retroalimentació als alumnes ràpida, de manera que estimuli el treball dels estudiants. L'experiència ha estat realitzada simultàniament a 859 alumnes matriculats de l'assignatura "Química", corresponent a 1r dels Graus d'Enginyeria de l'Energia (85), Enginyeria Aeroespacial (137), Enginyeria de les Tecnologies Industrials (459) i Enginyeria Química (141), durant el segon quadrimestre a l'Escola Tècnica Superior d'Enginyeria de la Universitat de Sevilla. S'han plantejat 5 probl…
Potencialidades de Google Maps en la investigación social aplicada
2019
In recent years, Google has devoted resources to build a complete map of the world. They constantly scan the territory, collecting a large amount of data that provides updated and complete geographic information. This allows us to have an interoperable map that provides the end user with a search tool, not only of routes but also of shops, equipment and any type of geo-referenced information. In addition, Google Maps provides a series of Application Programming Interface (API), which provides a library of set of subroutines, functions and procedures (in object-oriented programming) that can be used by other software to automate the extraction of information of the Google platform. These fre…
