(Universidad de ChileCyberDocs, 2010)El yacimiento de cobre con plata subordinada Mantos Blancos se encuentra ubicado 45 Km al noreste de la ciudad de Antofagasta, en el borde este de la Cordillera de la Costa. Actualmente el depósito es explotado mediante ...
-
(American Mathematical Society, 2016)We analyze a model optimal control problem for a 2D scalar conservation law: The so-called inverse design problem, the goal being to identify the initial datum leading to a given nal time con guration. The presence of ...
-
(IEEE-Inst Electrical Electronics Engineers, 2015)This paper presents a topology for a three-phase generation system for an isolated unbalanced load fed by a doubly fed induction generator with a neutral wire to include single-phase loads. The challenges of unbalanced ...
-
(Elsevier, 2017)This paper presents the design and application of fractional single-input–single-output (SISO) controllers to a grinding mill circuit, which is a multiple-input–multiple-output (MIMO) process. Two kinds of controllers are ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2012-07)In this paper a new control system for a 4-leg Matrix Converter (MC) feeding an isolated load is discussed. The proposed system is appropriate for wind-diesel schemes or any other application where a path for the circulation ...
-
(MDPI, 2020)The modular multilevel matrix converter has been proposed as a suitable option for high power applications such as flexible AC transmission systems. Among flexible AC transmission systems, the unified power flow controller ...
-
(Elsevier, 2013)The Doubly-Fed Induction Generator (DFIG) is one of the most widely used generators for wind energy applications with more than 50% of installed Wind Energy Conversion Systems (WECS) using this variable speed technology. ...
-
(Springer, 2015)Pathological crystallization of calcium oxalate (CaOx) inside the urinary tract is called calculi or kidney stone (Urolithiasis). CaOx exhibits three crystalline types in nature: CaOx monohydrate COM, dihydrate COD and ...
-
(WILEY-LISS, DIV JOHN WILEY & SONS INC, 2006-06)The sensory organs of the zebrafish lateral-line system (neuromasts) originate from migrating primordia that move along precise pathways. The posterior primordium, which deposits the neuromasts on the body and tail of the ...

-
(Academic Press-Elsevier, 2017)By using acoustic emission (AE) it is possible to control deviations and surface quality during micro milling operations. The method of micro milling is used to manufacture a submillimetre waveguide where micro machining ...
-
Control of dopaminergic neuron survival by the unfolded protein response transcription factor XBP1 (CrossMark, 2014)Parkinson disease (PD) is characterized by the selective loss of dopaminergic neurons of the substantia nigra pars compacta (SNpc). Although growing evidence indicates that endoplasmic reticulum (ER) stress is a hallmark ...
-
(2013)A combination of mineralogical (SEM–EDS, EMPA) and geochemical (redox dynamics, selective extractions) approaches was applied to mining- and smelting-impacted sediments from Lake Uru Uru and from the Cala Cala Lagoon, a ...
-
(Amer Assoc Advancement Science, 2021)Programmed cell death is regulated by the balance between activating and inhibitory signals. Here, we have identified RECS1 (responsive to centrifugal force and shear stress 1) [also known as TMBIM1 (transmembrane BAX ...
-
(Royal Soc. Chemistry, 2020)A family of hexaazamacrocyclic lanthanide complexes, [Ln(L-n)(NCS)(3)] (Ln(III) = Dy, Er; n = 1-3) has been synthesized and characterized by single-crystal X-ray diffraction, magnetic measurements and ab initio calculations. ...
