(INFORMS, 2017)For the past 12 years, the Chilean Professional Soccer Association (ANFP) hasapplied operations research (OR) techniques to schedule soccer leagues in Chile. Usinginteger programming-based methods, the ANFP decides which ...
-
(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 ...
-
(Oxford University, 2017)We present Gemini/GNIRS (Gemini Near-Infrared Spectrograph) spectroscopy of the Seyfert2 galaxy NGC 4388, with simultaneous coverage from 0.85 to 2.5μm. Several spatiallyextended emission lines are detected for the first ...
-
(Institute of Electrical and Electronics Engineers Inc., 2017)In the range α-majority query problem, we preprocess a given sequence S[1.n] for a fixed threshold α ϵ (0, 1], such that given a query range [i.j], the symbols that occur more than α (j-i+1) times in S[i.j] can be reported ...
-
(Springer, 2017)The dynamic of consolidation of urban areas inLatin America has allowed that almost 80% of the popula-tion concentrates in cities; this has produced changes in landcovers and modified regional climate, propitiating ...
-
(IEEE, 2017)In this paper we present a new system that uses new technology that has the ability to transmit data using light emitting diodes (LED) and a photodetector (PD) capable of sensing very soft changes of light. The system ...
-
(IEEE, 2017)We propose a hybrid filter to reduce the peak-to-average power ratio (PAPR) on the transmitter side in a long-term evolution uplink scheme. The design of the proposed filter is based on two key components: a finite impulse ...
-
(Institute of Mathematical Statistics, 2017)We investigate the problem of the rate of convergence to equilibrium for ergodic stochastic differential equations driven by fractional Brownian motion with Hurst parameterH >1/2 and multiplicative noise component σ. ...
-
(BioMed Central, 2017)Background: Amylases are used in various industrial processes and a key requirement for the efficiency of these processes is the use of enzymes with high catalytic activity at ambient temperature. Unfortunately, most ...
-
(John Wiley, 2017)Semi-conducting polyethylene (PE) nanocomposites with outstanding magnetic properties at room temperature were synthesized. These exceptional properties, for a diamagnetic and insulating matrix as PE, were obtained by ...
-
(ACM, 2017)We prove the existence of an algorithmAfor computing 2D or 3D convex hulls that is optimal forevery pointsetin the following sense: for every sequenceσofnpoints and for every algorithmA′in a certain classA,the running time ...
-
(Elsevier, 2017)tEnzymes active at low temperature are of great interest for industrial bioprocesses due to their highefficiency at a low energy cost. One of the particularities of naturally evolved cold-active enzymes istheir increased ...
-
(Springer, 2017)Discord Discovery is a recent approach for anomaly detection in time series that has attracted much research because of the wide variety of real-world applications in monitoring systems. However, finding anomalies by ...
-
(Institute of Physics Publishing, 2017)Numerical simulations were used to study the dynamics of a passive conservedscalar quantity entrained by a self-propelling viscous vortex ring. The trans-port and mixing process of the passive scalar variable were studied ...
-
(Institute of Physics Publishing, 2017)In multi-field inflation one or more non-adiabatic modes may become light, potentially inducing large levels of isocurvature perturbations in the cosmic microwave background. If in addition these light modes are coupled ...
-
(Elsevier, 2017)The synthesis of unsymmetrical ferrocenyl and cyrhetrenyl azines [(h5-C5H4)-CR¼N-N¼CH-2-C4H2X-5-NO2]M (M¼Re(CO)3, Fe(h5-C5H5); R¼H, CH3,X¼O, S) has led to the development of new derivativesof 5-nitroheterocycles as potential ...
-
(American Meteorological Society, 2017)The existence of strong easterly winds down the western slope of the south-central Andes in Chile, locallyknown as Puelche winds, has been known by the meteorological community since at least the mid-twentiethcentury. ...
-
(INFORMS Inst.for Operations Res.and the Management Sciences, 2017)Public transit systems in major urban areas usually operate under deficits and therefore require significant subsidies. An important cause of this deficit, particularly in the developing world, is the high fare evasion ...
-
(Springer Verlag, 2017)JavaScript systems are becoming increasingly complex and large. To tackle the challenges involved in implementing these systems, the language is evolving to include several constructions for programmingin- the-large. ...
-
(Cambridge University, 2017)Waves patterns in the Faraday instability have been studied for decades. Besides therich dynamics that can be observed on the waves at the interface, Faraday waves hidebeneath them an elusive range of flow patterns —or ...
