(ICSMGE, 2017)Evaluation of the seismic response of the Santiago Basin requires a shear wave velocity model with vertical and lateral variations that may explain the site effects reported during the 2010 Maule Earthquake. In order to ...
-
(ISSTT, 2017)The aim of this work is to improve high-frequency calibration data on longbaseline observations for the ALMA antennas. A dual-frequency atmospheric phase error calibration method is proposedand will be ...
-
(IEEE, 2017)The Ayllu Solar project’s main goal is to foster the sustainable development of rural/urban communities in Arica & Parinacota region, northern Chile, by means of using solar energy. This 5-year project is based on three ...
-
(IEEE, 2017)Due to the stochastic nature of equipment failures, the accurate assessment of power system reliability is a complex task. Consequently, the optimal selection of new network infrastructure to improve reliability is even ...
-
(Elsevier, 2017)Theoretical, experimental and observation data provide strong evidence that boiling is the dominant depositional mechanism in many low to intermediate sulfidation epithermal precious metals deposits. Textural and petrographic ...
-
(Springer, 2017)Automatic Speech Recognition (ASR) field has improved substantially in the last years. We are in a point never saw before, where we can apply such algorithms in non-ideal conditions such as real classrooms. In these scenarios ...
-
(American Physical Society, 2017)We report on an experimental, theoretical, and numerical study of slanted snaking of spatially localized parametrically excited waves on the surface of a water-surfactant mixture in a Hele-Shaw cell. We demonstrate ...
-
(Elsevier, 2017)Three seismic sequences of several thousand earthquakes each are analyzed by means of a tunable information recognizer known as wlzip. These sequences are different both in the geographical coverage and the time span, ...
-
(Oxford University Press, 2017)© 2017 The Authors. We report on the detection of a remarkable new fast high-energy transient found in the Chandra Deep Field-South, robustly associated with a faint (mR = 27.5mag, zph ~2.2) host in the CANDELS survey. The ...
-
(Institute of Electrical and Electronics Engineers Inc., 2017)Solar-based energy generation has increased by more than ten times over the same period. In total, worldwide electrical energy consumption increased by approximately 6340 TWh from 2003 to 2013. To meet the challenges created ...
-
(Elsevier, 2017)A thermoeconomic assessment of the joint production of electricity, fresh-water, cooling and heat for a solar polygeneration plant is carried out. The aims are to assess the actual cost of each product, to conduct a ...
-
(Public Library of Science, 2017)High species diversity of the potential animal host community for a zoonotic pathogen may reduce pathogen transmission among the most competent host, a phenomenon called the “dilution effect”, but the mechanisms driving ...
-
(IEEE, 2017)In this contribution we propose a new regularization method for the Generalized Matrix Learning Vector Quantization classifier. In particular we use a nuclear norm in order to prevent oversimplifying/over-fitting and ...
-
(IEEE, 2017)Segment Growing Neural Gas (Segment-GNG) has been recently proposed as a new spatiotemporal quantization method for time series. Unlike traditional quantization algorithms that are prototype-based, Segment-GNG uses segments ...
-
(Elsevier, 2017)In this paper, nonlinear finite element model updating (FEMU) is performed to study the prediction accuracy of a state-of-the-art finite element (FE) model of a seismic isolated bridge (SIB). The seismic isolator model ...
-
(IEEE, 2017)For power conversion systems interfaced to four-wire supplies, four-leg converters have become a standard solution. A four-leg converter allows good compensation of zero-sequence harmonics and full utilisation of the dc-link ...
-
The initial condition problem with complete history dependency in learning models for travel choices (Elsevier, 2017)Learning-based models that capture travelers’ day-to-day learning processes in repeated travel choices could benefit from ubiquitous sensors such as smartphones, which provide individual-level longitudinal data to help ...
-
Experimental Parameter Extraction in the Single-Diode Photovoltaic Model via a Reduced-Space Search (IEEE, 2017)The behavior of a photovoltaic (PV) module may be captured via its current-voltage (I-V) characteristic. The single-diode model is able to adequately fit this characteristic while featuring limited parameterization difficulty, ...
-
(Elsevier, 2017)Wildfires constitute the greatest economic disruption to Mediterranean ecosystems, from a socio-economic and ecological perspective (Molina et al., 2014). This study proposes to classify fire intensity levels based on ...
-
(IEEE, 2017)Internet access has become a requirement to participate in society; however, the majority of the world's population is not yet online. Citizens can self-organize cooperatively to crowdsource community network infrastructures ...
