Cluster analysis

Trabajo de investigaciónSe desarrolló un Componente Web de Clustering para Análisis de Datos el cual permite ingresar mediante una interfaz web y/o una API un conjunto de datos que son analizados mediante técnicas de clustering, estas técnicas permiten realizar agrupamiento de datos basados en sus características, y así arrojar un resultado que relaciona dichos datos. Lo anterior, busca proveer a la Universidad de una herramienta que permita de manera general, práctica y gratuita, realizar análisis de datos basados en clustering para cualquier estudio de investigación.INTRODUCCIÓN 1.

Phase Correlations and Topological Measures of Large-Scale Structure

The process of gravitational instability initiated by small primordial density perturbations is a vital ingredient of cosmological models that attempt to explain how galaxies and large-scale structure formed in the Universe. In the standard picture (the “concordance” model), a period of accelerated expansion (“inflation”) generated density fluctuations with simple statistical properties through quantum processes (Starobinsky [82], [83], [84]; Guth [39]; Guth & Pi [40]; Albrecht & Steinhardt [2]; Linde [55]). In this scenario the primordial density field is assumed to form a statistically homogeneous and isotropic Gaussian random field (GRF). Over years of observational scrutiny this paradigm has strengthened its hold in the minds of cosmologists and has survived many tests, culminating in those furnished by the Wilkinson Microwave Anisotropy Probe (WMAP; Bennett et al. [7]; Hinshaw et al. [45]

LOFT: the Large Observatory For X-ray Timing

The LOFT mission concept is one of four candidates selected by ESA for the M3 launch opportunity as Medium Size missions of the Cosmic Vision programme. The launch window is currently planned for between 2022 and 2024. LOFT is designed to exploit the diagnostics of rapid X-ray flux and spectral variability that directly probe the motion of matter down to distances very close to black holes and neutron stars, as well as the physical state of ultradense matter. These primary science goals will be addressed by a payload composed of a Large Area Detector (LAD) and a Wide Field Monitor (WFM). The LAD is a collimated (<1 degree field of view) experiment operating in the energy range 2-50 keV, with a 10 m[superscript 2] peak effective area and an energy resolution of 260 eV at 6 keV. The WFM will operate in the same energy range as the LAD, enabling simultaneous monitoring of a few-steradian wide field of view, with an angular resolution of <5 arcmin. The LAD and WFM experiments will allow us to investigate variability from submillisecond QPO’s to yearlong transient outbursts. In this paper we report the current status of the project
