Topology testing of phylogenies using least squares methods
2006
[Background] The least squares (LS) method for constructing confidence sets of trees is closely related to LS tree building methods, in which the goodness of fit of the distances measured on the tree (patristic distances) to the observed distances between taxa is the criterion used for selecting the best topology. The generalized LS (GLS) method for topology testing is often frustrated by the computational difficulties in calculating the covariance matrix and its inverse, which in practice requires approximations. The weighted LS (WLS) allows for a more efficient albeit approximate calculation of the test statistic by ignoring the covariances between the distances.
On thermoeconomics of energy systems at variable load conditions: integrated optimization of plant design and operation
2007
Abstract Thermoeconomics has been assuming a growing role among the disciplines oriented to the analysis of energy systems, its different methodologies allowing solution of problems in the fields of cost accounting, plant design optimisation and diagnostic of malfunctions. However, the thermoeconomic methodologies as such are particularly appropriate to analyse large industrial systems at steady or quasi-steady operation, but they can be hardly applied to small to medium scale units operating in unsteady conditions to cover a variable energy demand. In this paper, the fundamentals of thermoeconomics for systems operated at variable load are discussed, examining the cost formation process an…

Search for new phenomena in final states with large jet multiplicities and missing transverse momentum at s√=8 TeV proton-proton collisions using the…
2013
A search is presented for new particles decaying to large numbers (7 or more) of jets, with missing transverse momentum and no isolated electrons or muons. This analysis uses 20.3 fb[superscript −1] of pp collision data at s√ = 8 TeV collected by the ATLAS experiment at the Large Hadron Collider. The sensitivity of the search is enhanced by considering the number of b-tagged jets and the scalar sum of masses of large-radius jets in an event. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of various simplified supersymmetry-inspired models where gluinos are pair produced, as well as an mSUGRA/CMSSM model.
Postmortem Computed Tomography: From Acquisition to Reporting
2019
PMCT in a noninvasive, fast, and quite available method which coroners and forensic experts tend to use more and more often, especially when a crime is suspected. PMCT proved to be an excellent tool for detection and assessment of bone fracture injuries due to sharp trauma and bullet trajectories.
Infrared image processing and its application to forest fire surveillance
2007
This paper describes an scheme for automatic forest surveillance. A complete system for forest fire detection is firstly presented although we focus on infrared image processing. The proposed scheme based on infrared image processing performs early detection of any fire threat. With the aim of determining the presence or absence of fire, the proposed algorithms performs the fusion of different detectors which exploit different expected characteristics of a real fire, like persistence and increase. Theoretical results and practical simulations are presented to corroborate the control of the system related with probability of false alarm (PFA). Probability of detection (PD) dependence on sign…
Automatic image representation for content-based access to personal photo album
2007
The proposed work exploits methods and techniques for automatic characterization of images for content-based access to personal photo libraries. Several techniques, even if not reliable enough to address the general problem of content-based image retrieval, have been proven quite robust in a limited domain such as the one of personal photo album. In particular, starting from the observation that most personal photos depict a usually small number of people in a relatively small number of different contexts (e.g. Beach, Public Garden, Indoor, Nature, Snow, City, etc...) we propose the use of automatic techniques borrowed from the fields of computer vision and pattern recognition to index imag…

PRÁCTICAS DEL ANÁLISIS FACTORIAL EXPLORATORIO (AFE) EN LA INVESTIGACIÓN SOBRE CONDUCTA DEL CONSUMIDORY MARKETING
2012
El Análisis Factorial Exploratorio (AFE) es una de las técnicas estadísticas más utilizadas en la investigación social. El principal objetivo de este trabajo es describir las prácticas más utilizadas por los investigadores en el área de la conducta del consumidor y el marketing. Mediante una metodología de revisión documental se analizan las prácticas de AFE en cinco revistas españolas dedicadas a dicha temática (2000-2010). Se analizan las elecciones de los investigadores relacionadas con el modelo factorial, el criterio de retención, la rotación, la interpretación de los factores y otras cuestiones relevantes para el análisis factorial. Los resultados sugieren que los investigadores ejecu…
Scientific studies on writing in second language learning (2005-2017)
2019
Este artículo revisa críticamente las líneas temáticas que desde 2005 hasta 2017 se han publicado sobre Second Language Writing (SLW) con el objetivo de presentar un análisis de las tendencias predominantes en las publicaciones indexadas en SCOPUS. Como metodología de estudio se ha procedido a la selección de aquellas contribuciones que han recibido 60 citas o más. De la revisión de literatura científica realizada se concluye que son tres las líneas de investigación mayoritarias: el proceso de composición o redacción del texto escrito; la retroalimentación que el docente ofrece al aprendiz; y la escritura en línea de una L2. Las conclusiones señalan la necesidad de profundizar en la investi…
