(IEEE, 2008)Mobile computing devices facilitate mobility and face-to-face interaction when compared with desktop computing, but lacks of the computing power of the latter. Therefore, a key aspect to ensure success of a learning ...
-
(Springer-Verlag, 2008)Ubiquitous computing is increasingly becoming part of our lives. Various computing devices, having different sizes and capabilities, and using different software platforms are part of our working, leisure and living ...
-
(2008-05)Organizations orchestrate work along a continuum of structured and unstructured activities. Particularly in emergency situations and crisis management scenarios, the organization’s procedures and information systems ...
-
(SPRINGER, 2006-11)In this paper, we prove a new version of the Second Welfare Theorem for economies with a finite number of agents and an infinite number of commodities, when the preference correspondences are not convex-valued and/or when ...
-
(American Chemical Society, 2015)Understanding biological interaction with graphene and hexagonal-boron nitride (h-BN) membranes has become essential for the incorporation of these unique materials in contact with living organisms. Previous reports show ...
-
(Elsevier, 2016)Sensitivity to frequency offset in orthogonal frequency division multiplexing (OFDM)-based systems allow unwanted interference among the subcarriers, which results in intercarrier interference (ICI). A novel family of ...
-
(Elsevier, 2019)Association constants and thermodynamicsparameters on inclusion of four 3-amido coumarins that present trypanocidal activity, into 6-amino-beta-cyclodextrin (1: 1 stoichimetry) were determined. In addition, pure ...
-
(Springer, 2013)Let A2(t) be the Airy2 process. We show that the random variable sup t≤α A2(t) −t 2 +min{0,α}2 has the same distribution as the one-point marginal of the Airy2→1 process at time α. These marginals form a family of ...
-
(ELSEVIER, 2010)A surface acoustic wave can interact with dislocations that are close to the surface. We characterize this interaction and its manifestations as scattered surface acoustic waves for different orientations with respect ...
-
(MDPI, 2022)Thin films of BiFeO3, VO2, and BiFeO3/VO2 were grown on SrTiO3(100) and Al2O3(0001) monocrystalline substrates using radio frequency and direct current sputtering techniques. To observe the effect of the coupling between ...
-
(Springer, 2013)This paper analyzes the influence of circulation anomalies on the magnitude of minimum air temperature (Tmin) at a daily scale in two important agricultural valleys of Chile (Maipo and Casablanca) during the period ...
-
(EDP Sciences, 2013)Most of the objects in the trans-Neptunian belt (TNb) and related populations move in prograde orbits with low eccentricity and inclination. However, the list of icy minor bodies moving in orbits with an inclination above ...
-
(ELSEVIER, 2006-06-06)This paper presents the results of a study concerned with the surface hardening of nonferrous and ferrous alloys, by integrating the electrospark deposition and plasma nitriding processes. Specimens of an aluminium bronze ...
-
(Taiwan Association for Aerosol Research, 2017)The local meteorological factors of the cold season nocturnal particulate matter (PM) air quality problem in the western urban area of Santiago City are documented and analyzed by means of three years of multi-level ...
-
(Elsevier, 2014)The effect of the high frequency (synoptic) variability of wind and heat fluxes upon the surface ocean off south-central Chile (west coast of South America) is investigated using a regional ocean model. We focus our ...
-
(Copernicus Gesellschaft, 2017-05-31)The knowledge of surface ozone mole fractions and their global distribution is of utmost importance due to the impact of ozone on human health and ecosystems and the central role of ozone in controlling the oxidation ...
-
(Elsevier, 2018)Diamond-like carbon (DLC) films and nanocrystalline silver particles containing diamond-like carbon (DLC:Ag) films were electrodeposited on n-type silicon substrate (n-Si) to prepare n-Si/DLC and n-Si/DLC:Ag heterostructures ...
-
(Wiley-VCH Verlag, 2019)Surface texturing has gained great attention in the tribological community since precisely defined surface features can help to reduce friction and/or wear irrespective of the acting lubrication regime. The ability to ...
-
(Elsevier, 2017-07-01)We describe extended occurrences of unusual silicate glass surface layers from the Atacama Desert (Chile). These glasses, found near the town of Pica at four localities separated by up to 70 km, are neither fulgurites, nor ...
-
(AMER INST PHYSICS, 2016)We study the propagation of monochromatic surface waves on a turbulent flow of liquid metal, when the waves are much less energetic than the background flow. Electromagnetic forcing drives quasitwo- dimensional turbulence ...
