-
(IEEE Institute of Electrical and Electronics Engineers, 2018)We present a novel approach to design a high-performance tapered slot antenna (TSA) at millimeter-wave frequencies. Commonly, TSAs are designed using profiles expressed as simple functions (linear, exponential, Fermi, or ...
-
(Wiley, 2017)BACKGROUND: The efficient, controlled and robust purification of conjugates from PEGylation has a growing demand in the biopharmaceutical's market. In general, the yield and purity reached through the conventional ...
-
(IOP Publishing Ltd, 2017)New means of interstellar travel are now being considered by various research teams, assuming lightweight spaceships to be accelerated via either laser or solar radiation to a significant fraction of the speed of light ...
-
(Elsevier, 2015)This communication revisits previously reported results on froth depth profiling along a rougher flotation bank. The optimization problem is reformulated as to maximize the overall bank Cu recovery subject to a lower bound ...
-
(Sage, 2020)A solution strategy based on integer linear programming models has been developed for leaf sweeping operations in the Argentine city of Trenque Lauquen. The aim is to achieve efficiency in the assignment of sweepers to ...
-
(2012-02)We present a methodology for long-term mine planning based on a general capacitated multicommodity network flow formulation. It considers underground and open-pit ore deposits sharing multiple downstream processing plants ...
-
(John Wiley & Sons, 2013)When a company decides to outsource a service, the most important reasons for doing so usually are to focus on core business, to be able to access high-quality services at lower costs, or to benefit from risk sharing. ...
-
(Southern African Inst Mining Metallurgy, 2016-07)A crucial problem in the open pit mining industry is to determine the optimal block scheduling, defining how the orebody will be sequenced for exploitation. An orebody is often comprised of several thousand or million ...
-
(2013)Salmon farming in Chile constitutes one of the nation's principal food exporting sectors. In the seawater stage, one of the most important in the farm production chain, salmon are cultivated in floating cages fitted with ...
-
(Elsevier B.V., 2019)© 2019 This paper describes the creation, development, implementation and impact of a system optimizing the distribution of petroleum products by pipeline at Empresa Nacional del Petroleo, the state-owned oil company in ...
-
(Elsevier, 2020)The SART (Sulfidization, Acidification, Recycling and Thickening) process has been successfully installed to recover cyanide and copper in seven worldwide gold cyanidation plants in the last 15 years. This technology has ...
-
(Elsevier, 2020)The problem studied in this paper is that of designing the optimal open pit haulage ramp that, for a given ramp width and a maximum ramp gradient, connects two points of the mine, minimising construction and operational ...
-
(Academic Press Inc., 2019)The design of effective incentive schemes that are both successful in motivating employees and keeping down costs is of critical importance. Research has demonstrated that prosocial incentives, where individuals’ effort ...

(EDP Science, 2020)Context. Detecting and characterizing substellar companions for which the luminosity, mass, and age can be determined independently is of utter importance to test and calibrate the evolutionary models due to uncertainties ...
-
(IOP Publishing Ltd., 2017)We present orbital elements and mass sums for 18 visual binary stars of spectral types B to K (five of which are new orbits) with periods ranging from 20 to more than 500 yr. For two double-line spectroscopic binaries with ...
-
(ESO, 2016-03)Aims. We present new astrometric measurements of the components in the T Tauri system and derive new orbits and masses. Methods. T Tauri was observed during the science verification time of the new extreme adaptive ...
