(Elsevier, 2017)The q-Weibull model is based on the Tsallis non-extensive entropy [22] and is able to model various behaviors of the hazard rate function, including bathtub curves, by using a single set of parameters. Despite its flexibility, ...
-
(Elsevier, 2017)Typically, development of robot behavior entails writing the code, deploying it on a simulator or robot and running it in a test setting. If this feedback reveals errors, the programmer mentally needs to map the error in ...
-
(Elsevier, 2017)This study assesses the environmental impact and the potential valorization of metal-sludge waste generated by the active neutralization of extremely metal-polluted acid mine drainage (AMD). To this end, two regulated ...
-
(Elsevier, 2017)This paper examines the determinants of perceived and actual knowledge of commission paid by contributors in the Chilean pension funds industry. Results show that price consciousness and brand credibility are positively ...
-
(Taylor and Francis, 2017)A methodology is presented for deciding the location of a third ore crusher to be installed at Chile’s Chuquicamata copper mine. The proposed approach determines which location alternative exhibits the minimum capital and ...
-
(Elsevier, 2017)The method for the deconvolution of overlapping DSC peaks here proposed has been used by the first time for the quantitative determination of the enthalpies associated to the phase transitions undergone during the aging ...
-
(Elsevier, 2017)This paper presents a novel prognostic method that allows a proper characterization of the uncertainty associated with the evolution in time of nonlinear dynamical systems. The method assumes a state-space representation ...
-
An entropy-based technique for classifying bacterial chromosomes according to synonymous codon usage (Springer, 2017)We present a framework based on information theoretic concepts and the Dirichlet distribution for classifying chromosomes based on the degree to which they use synonymous codons uniformly or preferentially, that is, whether ...
-
(Elsevier, 2017)tThis study presents a novel load estimation method for isolated communities that do not receive energyor only receive it for a limited time each day. These profiles have been used to determine the installedcapacity of ...
-
(Elsevier, 2017)Raman spectroscopy has proven to be an effective tool to confirm the presence and abundance of CO2 in fluid and melt inclusions. The Ramanmethod for quantifying CO2 abundance is based on the observation that the ...
-
(Springer, 2017)This paper presents a new family of solutions to the singularly perturbed Allen-Cahn equation α2Δu + u(1 − u2) = 0 in a smooth bounded domain Ω ⊂ R3, with Neumann boundary condition and α > 0 a small parameter. These ...
-
(Springer, 2017)Pulse shaping is used in orthogonal frequency division multiplexing (OFDM) based systems to reduce inter-carrier interference (ICI) power and peak-to-average power ratio (PAPR), which are considered the major weaknesses ...
-
(BioMed Central, 2017)Background: Several query federation engines have been proposed for accessing public Linked Open Data sources. However, in many domains, resources are sensitive and access to these resources is tightly controlled by ...
-
(Wiley, 2017)The prediction of reactivity is one of the long-standing objectives of chemistry, contributing to enforce the link between theory and experiment. In particular, the regioselectivity of aromatic molecules has motivated the ...
-
(Wiley, 2017)Novel multifunctional scaffolds for bone regeneration can be developed by incorporation of bioactive glasses (BG) doped with therapeutic and antibacterial metal ions, such as copper (Cu) and zinc (Zn), into a biodegradable ...
-
(IOP Publishing, 2017)We observed 13 Planck cold clumps with the James Clerk Maxwell Telescope/SCUBA-2 and with the Nobeyama 45 m radio telescope. The N2H+ distribution obtained with the Nobeyama telescope is quite similar to SCUBA-2 dust ...
-
(IEEE, 2017)Innovative solutions for smart transportation involve the integration of communication technologies, mobile applications, control mechanisms, and human-to-machine interfaces. In this demo we present the prototype of a ...
-
(Southwest Missouri State University, 2017)This paper is devoted to construction of new solutions to the Cahn-Hilliard equation in ℝd. Staring from the Delaunay unduloid Dô with parameter τ ∈ (0, τ∗) we find for each sufficiently small ε a solution u of this equation ...

(Elsevier, 2017)The Andean IOCG clan in the Coastal Cordillera of northern Chile, comprises the iron oxide-Cu-Au sensu stricto, the iron oxide-apatite (IOA), and the stratabound Cu(-Ag) deposits, also known as Manto-type Cu(-Ag) ...
