(Elsevier Ltd, 2018)The extremely high dielectric constant of the cubic perovskite CaCu3Ti4O12 (CCTO) has attracted increasing attention for a variety of capacitive elements in microelectronic device applications. In this research, the ...
-
(Institute of Electrical and Electronics Engineers Inc., 2018)We introduce a new technique for the efficient management of large sequences of multi-dimensional data, which takes advantage of regularities that arise in real-world datasets and supports different types of aggregation ...
-
Optimization of lime and clay-based hemp-concrete wall formulations for a successful lime rendering (Elsevier Ltd, 2018)Different pathologies may arise on a wall finish if this is applied on a hemp-based rammed wall that is not completely dry. By simulating uneven drying and early-rendering of load-bearing and non-load-bearing hemp concrete ...
-
(Elsevier B.V., 2018)Anomalous Microwave Emission (AME) is a component of diffuse Galactic radiation observed at frequencies in the range ≈ 10–60 GHz. AME was first detected in 1996 and recognised as an additional component of emission in 1997. ...
-
(Walter de Gruyter GmbH, 2018)We report new results of a combined focused ion beam and high-resolution transmission electron microscopy (FIB/HRTEM) investigation of platinum-group elements (PGE)-rich base-metal sulfides. The Ni-Fe-Cu base-metal ...

(Academic Press Inc., 2018)In this article we study the long term behavior of the competitive system {[Formula presented]=∇⋅[α(x)∇[Formula presented]]+u(m(x)−u−bv)inΩ,t>0,[Formula presented]=∇⋅[β(x)∇v]+v(m(x)−cu−v)inΩ,t>0,∇[Formula ...
-
(IEEE, 2018)This paper presents a simple and innovative Capacitor Voltage Balancing (CVB) strategy for Modular Multilevel Converters (MMC) based on full H-bridge cell topologies. The method computes specific modulation indexes for ...
-
(Elsevier Ltd, 2018)Background: The economic evaluation of colorectal cancer screening is challenging because of the need to model the underlying unobservable natural history of the disease. Objectives: To describe the available Markov ...
-
(Institute of Physics Publishing, 2018)We present molecular line observations of the high-mass molecular clump IRAS 16562−3959 taken at 3 mm using the Atacama Large Millimeter/submillimeter Array (ALMA) at 1. 007 angular resolution (0.014 pc spatial resolution). ...
-
(Elsevier GmbH, 2018)A polyphasic study was undertaken to establish the taxonomic status of three representative Geodermatophilus strains isolated from an extreme hyper-arid Atacama Desert soil. The strains, isolates B12T, B20 and B25, were ...
-
(Springer Verlag, 2018)El Romeral is one of the largest iron oxide-apatite (IOA) deposits in the Coastal Cordillera of northern Chile. The Cerro Principal magnetite ore body at El Romeral comprises massive magnetite intergrown with actinolite, ...
-
(Elsevier Ltd, 2018)An Eco-Industrial Park (EIP) is a community of businesses that seeks to reduce the global impact by sharing material. The connections among the industrial participants within this park improve the environmental performance ...
-
(Elsevier Ltd, 2018)We develop accident prediction models for a stretch of the urban expressway Autopista Central in Santiago, Chile, using disaggregate data captured by free-flow toll gates with Automatic Vehicle Identification (AVI) which, ...
-
(Springer Verlag, 2018)We present a teacher support system to enable inter-class integration with Cross-Border Public Classes. These are lessons where students from classes in two different countries participate in the same lesson synchronously, ...
-
(Springer Netherlands, 2018)In this work we are interested in the Demyanov–Ryabova conjecture for a finite family of polytopes. The conjecture asserts that after a finite number of iterations (successive dualizations), either a 1-cycle or a 2-cycle ...
-
(Inter-Research, 2018)Traditionally temperate and hyper-humid, western Patagonia experienced its most severe drought during the summer and fall of 2016. Along with precipitation deficits larger than 50% there was a similar reduction in river ...
-
(Springer Verlag, 2018)© Springer International Publishing AG 2018. One of the main goals of elementary school STEM teachers is that their students write their own explanations. However, analyzing answers to question that promotes writing is ...
-
(Springer New York LLC, 2018)This paper presents an algorithm for simulating Gaussian random fields with zero mean and non-stationary covariance functions. The simulated field is obtained as a weighted sum of cosine waves with random frequencies and ...
-
(Elsevier B.V., 2018)A spatial modeling was applied to Chilean wildfire occurrence, through the Dempster-Shafer's evidence theory and considering the 2006–2010 period for the Valparaiso Region (central Chile), a representative area for this ...
-
(Taylor and Francis Ltd., 2018)The stability graph method is widely used for open stope mine design. During the development of the method the effect of induced stresses were included by using two-dimensional or limited three-dimensional stress analysis. ...
