(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 ...
-
(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 ...
-
(IEEE, 2017)Both economics and stability analysis are critical to operate electricity networks in an efficient and secure manner, especially in the context of microgrids, where more complex stability phenomena ...
-
(Techno Press, 2017)The use of Hollow Structural Sections (HSS) provides an alternative for steel buildings in seismic zones, with the advantage over WF columns that the HSS columns have similar resistance along both axes and enhanced performance ...
-
(Elsevier, 2017)In this work, we revisit a problem of optimal control for the maximisation of biogas production in a continuous bioreactor, for which the analytical determination of the optimal synthesis is an open problem. We consider ...
-
(Elsevier, 2017)In this study, polycaprolactam (PA6) nanocomposites with thermally reduced graphene oxide (TrGO) and carbon nanotubes (CNTs) were prepared by melt blending with the aim of obtaining films with improvements in permeability ...
-
(Copernicus GmbH, 2017)Since 2010 an uninterrupted sequence of dry years, with annual rainfall deficits ranging from 25 to 45 %, has prevailed in central Chile (western South America, 30-38 degrees S). Although intense 1-or 2-year droughts are ...
-
(IEEE, 2017)Video streaming over the Internet is challenging due to the varying intrinsic and extrinsic network conditions such as loss rates, throughput and delay. In this work, a cross-layer solution using scalable video coding in ...
-
(Springer, 2017)Bubbles are pairs of internally vertex-disjoint (s, t)-paths with applications in the processing of DNA and RNA data. For example, enumerating alternative splicing events in a reference-free context can be done by enumerating ...
