(Elsevier, 2017)The geomorphology of the Denton Hills provides insight into the timing and magnitude of glacial retreats in a region of Antarctica isolated from the influence of the East Antarctic ice sheet. We present 26 Beryllium-10 ...

Almost partitioning 2-edge-colourings of 3-uniform hypergraphs with two monochromatic tight cycles (Elsevier B.V., 2017)We show that any 2-colouring of the 3-uniform complete hypergraph Kn (3) on n vertices contains two disjoint monochromatic tight cycles of distinct colours covering all but o(n) vertices of Kn (3). The same result holds ...
-
(Elsevier, 2017)Understanding the evolution of a volcanic edifice is important in establishing its associated geological hazards. Apacheta and Aguilucho volcanoes, northern Chile, formed a volcanic complex with known fumaroles and geo-thermal ...
-
(Elsevier, 2017)The precipitation kinetics of secondary phases in a 10.5%Cr heat resistant steel, designed by the authors, was studied experimentally and theoretically. Experimental data of nucleation, growth and coarsening stages for ...
-
(Taylor and Francis, 2017)Recoverable mineral resources assessment has become a standard geostatistical application in the mining industry, with various geostatistical techniques currently available. This investigation aimed to improve the prediction ...
-
(Heldermann Verlag, 2017)Bregman distances play a key role in generalized versions of the proximal algorithm. This paper proposes a new characterization of Bregman distances in terms of their gradient and Hessian matrix. Thanks to this characterization, ...
-
(Elsevier, 2017)The Tolhuaca Volcano near Lonquimay in south-central Chile has been the subject of several studies due to its geothermal manifestations, but little is known about the stratigraphy and reservoir potential of the Cura-Mallin ...
-
(Elsevier, 2017)Small eruptive centres commonly have more primitive lavas than those associated with stratovolcanoes, an observation that has been taken to indicate a short magma residence in the crust relative to those reservoirs below ...
-
(American Physical Society, 2017)Future cosmic microwave background polarization experiments will search for evidence of primordial tensor modes at large angular scales, in the multipole range 4≤≤50. Because in that range there is some mild evidence of ...
-
(IEEE, 2017)A model of the power coefficient of a mid-scale Magnus wind turbine using numerical solutions of the Blade Element Momentum Theory and symbolic regression is presented. A direct method is proposed for solving the nonlinear ...
-
(IEEE, 2017)Multimedia searches often return items that can becategorized into several “topics”, allowing users to disambiguateand explore answers more efficiently. In this paper we investigatemethods for clustering tags associated ...
-
(Springer, 2017)Our interdisciplinary research is dedicated to exploring the boundaries of stereoscopic filmmaking from an unusual viewpoint: we aim at creating 3D non-photorealistic cinema which allows conciliating a stereoscopic ...
-
(Springer, 2017)A fluid queuing network constitutes one of the simplest mod-els in which to study flow dynamics over a network. In this model wehave a single source-sink pair and each link has a per-time-unit capac-ity and a transit time. ...
-
(Institute of Physics, 2017)The goal of this work is to describe a framework to propagate uncertainties in piezoelectricenergy harvesters(PEHs). These uncertainties are related to the incomplete knowledge of themodel parameters. The framework presented ...
-
(Springer, 2017)The precipitation hardening of a Cu-11Ni-19Zn-1Sn alloy has been studied by means of Differential Scanning Calorimetry (DSC), High-Resolution Transmission Electron Microscopy (HRTEM), and hardness measurements. The ...
-
(Oxford University, 2017)CO observations allow estimations of the gas content of molecular clouds, which trace thereservoir of cold gas fuelling star formation, as well as to determine extinction via H2col-umn density, N(H2). Here, we studied ...
-
(Universidad Nacional Autonoma de Mexico, 2017)Based on the molecular emission in the 12CO(2-1) and 13CO(2-1) lines, and on the continuum emission in the MIR and FIR towards the S 21 IR dust bubble, we analyze the physical characteristics of the gas and dust linked to ...
-
(SAGE, 2017)This article presents a robotic dataset collected from the largest underground copper mine in the world. The sensor mea-surements from a 3D scanning lidar, a 2D radar, and stereo cameras were recorded from an approximately ...
-
(American Society of Civil Engineers (ASCE), 2017)Observations following recent earthquakes, and from structural testing, indicate numerous brittle compression failures in rein-forced concrete seismic-resisting walls. This is unexpected, as most seismic-resisting walls ...
-
(IEEE, 2017)Modular multilevel converters (M2C) are considered an attractive solution for high power drive applications. However, energy balancing within the converter is complex to achieve, particularly when the machine is operating ...
