(American Institute of Physics Inc., 2017)Time-delayed feedback plays an important role in the dynamics of spatially extended systems. In this contribution, we consider the generic Lugiato-Lefever model with delay feedback that describes Kerr optical frequency ...
-
(IEE, 2017)It is well-know that carrier frequency offset in the subcarriers of orthogonal frequency division multiplexing (OFDM) leads to intercarrier interference (ICI); therefore, system degradation occurs. Nevertheless, this issue ...
-
(American Institute of Physics, 2017)Graphite is a versatile material with many applications. Its intrinsic density has been extensively studied and quantified experimentally and theoretically. Experimental data suggest that the electron and hole densities ...
-
(ISSTT, 2017)The Low Frequency Array instrument at SOFIA is a heterodyne array designed to observe in the complete range between 1.9 and 2.5 THz. It is a 14 pixel instrument, working in a dual polarization configuration. To provide ...
-
(Elsevier, 2017)In mineral resources evaluation, the joint simulation of a quantitative variable, such as a metal grade, and a categorical variable, such as a rock type, is challenging when one wants to reproduce spatial trends of the ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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)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 ...
-
(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 ...
-
(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 ...
