Binder jet printing (BJP) is a metal additive manufacturing method that manufactures parts with complex geometry by depositing powder layer-by-layer, selectively joining particles in each layer with a polymeric binder and finally curing the binder. After the printing process, the parts still in the powder bed must be sintered to achieve full densification (A. Mostafaei, Y. Behnamian, Y.L. Krime...

We present an overview of the existing localization algorithms which have been or are being used to perform quantum chemical molecular calculations that take into account electronic correlation effects. The natural distinction between intrinsic and extrinsic localization methods is explained and developed. The advantages and drawbacks of specific methods are discussed in terms of CPU time requi...

In this study the concept of alignment is analyzed by presenting the results of a study that examines the degree of alignment between a standardized mathematics assessment and a set of academic standards. The alignment was examined using the Webb model and the results suggest that the degree of alignment between standardized assessments and academic content standards is not the most appropriate...

In February 2005, the Kyoto Protocol to the United Nations Framework Convention on Climate Change came into force, but without participation by the United States. Its impacts on emissions of greenhouse gases—including carbon dioxide (CO2), the primary anthropogenic driver of climate change—will be trivial; but scientific (Robert T. Watson, 2001) and economic (Charles D. Kolstad and Michael A. T...

In an economy with multiple consumption goods (including environmental amenities) that uniquely maximises the present value of utility with constant discounting, constant or falling augmented green net national product, or zero or negative augmented net investment, at any time implies that the economy is unsustainable then. "Augmented" means that time is treated as a productive stock, so augmen...

Se desarrolla un análisis bibliométrico sobre artículos científicos referentes a México en temas de ciberseguridad, publicados entre 2015 y 2020 e indizados los portales ScienceDirect, Redalyc Dialnet. toman consideración indicadores como la productividad por año, revista, institución autor, así el contenido temático textos. De 18 analizados se detectan tendencias investigativas que sugieren un...

This paper deals with numerical functions able to functionally express operators defined as , and verifying either Modus Ponens or Modus Tollens, or both. The concrete goal of the paper is to search for continuous t-norms and strong-negation functions for which it is either (Modus Ponens), or (Modus Tollens), or both, for all in and a given . Functions are taken among those in the most usual fa...
