(Ediciones Doyma, S.L., 2020)Introduction: Autoimmune Bullous Diseases (ABDs) are acquired dermatoses characterised by blisters on the skin and mucous membranes. The aim of this study is to describe the epidemiology, clinical features, therapeutic ...
-
(Universidad de Chile, 2008)Los autoíndices comprimidos para texto ofrecen una funcionalidad similar a la de los índices clásicos, ocupan espacio proporcional al tamaño del texto comprimido, y además lo reemplazan, pues son capaces de reproducir ...

(MDPI, 2021)We propose a monochromatic low-cost automatic sun photometer (LoCo-ASP) to perform distributed aerosol optical depth (AOD) measurements at the city scale. This kind of network could fill the gap between current automatic ...
-
(Elsevier, 2016)Sleep Disordered Breathing (SDB) is a group of diseases that affect the normal respiratory function during sleep, from primary snoring to obstructive sleep apnea (OSA) being the most severe. SDB can be detected using a ...
-
(Elsevier, 2017)Background and objective: Infertility is a problem that affects up to 15% of couples worldwide with emotional and physiological implications and semen analysis is the first step in the evaluation of an infertile couple. ...
-
(Universidad de Chile, 2018)El Survey de Transientes a Alta Cadencia (HiTS), fue creado con el propósito de descubrir y estudiar objetos transitorios con escalas de tiempo características entre horas y días, tales como, estrellas pulsantes, eclipsantes, ...
-
(MDPI, 2020)Bridges are a critical piece of infrastructure in the network of road and rail transport system. Many of the bridges in Norway (in Europe) are at the end of their lifespan, therefore regular inspection and maintenance are ...
-
(Springer, 2017)In this work, new strategies for automatic identification of P- and S-wave arrival times from digital recorded local seismograms are proposed and analyzed. The database of arrival times previously identified by a human ...
-
(Elsevier, 2016)In this paper we propose an automatic volcano event detection system based on Hidden Markov Model (HMM) with state and event duration models. Since different volcanic events have different durations, therefore the state ...
-
(MDPI, 2022)This paper describes a system for the automatic determination of rock-breaking target poses for impact hammers used in underground mines. The rock-breaking target pose is defined as the position and angle at which the ...
-
(ELSEVIER, 2010)In this paper the nature and relevance of the information provided by intonation is discussed in the framework of second language learning. As a consequence, an automatic intonation assessment system for second language ...
-
(ELSEVIER, 2010)A numerical method for 2D LEFM crack propagation simulation is presented. This uses a Lepp–Delaunay based mesh refinement algorithm for triangular meshes which allows both the generation of the initial mesh and the local ...
-
(2012-12-18)In this article we present an automatic on-line color calibration system that makes extensive use of the spatial relationships between color classes in the color space. First, we introduce the definition of class-relative color ...
-
Automatic space object detection on all-sky images from a synoptic survey synthetic telescope array (Elsevier, 2020)Detection, classification, and characterization of Space Objects (SOs) are important tasks in many areas of research. Detection of SOs is important in predicting collisions with debris that could become hazards for satellites ...
-
(Taylor & Francis, 2015)Even though block caving mining method is already the most economical underground mining method for large massive ore bodies, it requires further technical advancements to also become a practical method for deep deposits ...
-
(Universidad de Chile, 2011)La norma técnica eléctrica chilena menciona que dentro del sistema eléctrico no se debe propagar falla, en particular del sistema de subtransmisión enmallado de una distribuidora hacia el sistema de transmisión troncal. ...
-
(Universidad de Chile, 2023)Las empresas de agricultura orgánica son relativamente nuevas en Chile y ofrecen una alternativa a la agricultura convencional que es más beneficiosa para el medio ambiente ya que no usan productos nocivos, minerales o ...
-
(Universidad de Chile, 2021)La construcción industrializada está llegando a Chile y para quedarse, empresas como BauMax y MultiAceros están siendo pioneras en las nuevas tecnologías de construcción que involucran elementos prefabricados, principalmente ...
-
(Universidad de Chile, 2018)En el desarrollo de software, existen tres elementos determinantes para la obtención de sistemas de calidad, estos son: las personas, la tecnología y los procesos, teniendo los procesos una incidencia significativa en la ...
