"En los sistemas de distribución de energía el eléctrica típicos es común encontrar cargas de tipo monofásico. Sin embargo estos sistemas son generalmente desbalanceados, debido a que la cargas son desigualmente distribuidas entre las fases, y distorsionados por la gran…

Torres-Saillant’s book contends, as its author explains, that as a region the Caribbean is a differentiated “civilizational” zone produced by the encounter of multiple cultures and by contending political and economic interests. This region, according to him, has produced an…

Introduction: The use of computer-generated 3-dimensional (3-D) anatomical models to teach anatomy has proliferated. However, there is little evidence that these models are educationally effective. The purpose of this study was to test the educational effectiveness of a computer-generated 3-D…

This essay contests the view that humanity’s centuries-long experience with clocks is marked by a steady increase in time awareness that culminated in the modern compulsion known as “time discipline”. It argues, in contrast, that modern time discipline emerged during…

Electoral authoritarian regimes represent the modal type of political regimes in the developing world. To control electoral outcomes, such regimes may deploy a broad variety of repressive and manipulative measures. Despite their empirical as well as normative relevance, we possess…

"We shortly recall the mathematical and physical aspects of Talbot’s self-imaging effect occurring in near-field diffraction. In the rational paraxial approximation, the Talbot images are formed at distances z = p/q, where p and q are coprimes, and are superpositions…

The objective of this research is to elaborate an endogenous growth
model which allows us to examine the mutual interaction between economic
growth, labour market behaviour and population growth. We show how the
introduction of disequilibrium and some nonlinearities give…

The study of natural fluctuations has been of great interest for
economists for decades. Although the earliest formal models of business
cycles, around the 1950s, were endogenous (Hicks, Kaldor, Goodwin), the
dominant strategy during the most of the last century…

Physical orientation was a central philosophical problem for German thinkers in the late eighteenth century. Moses Mendelssohn, for instance, pondered in Morgenstunden, o Vorlesungen uber das Daseyn Gotten (1785) whether one can orient oneself in the metaphysical realm with the…

Many asymptotic results for kernel-based estimators were established under some smoothness assumption on density. For cases where smoothness assumptions that are used to derive unbiasedness or asymptotic rate may not hold we propose a combined estimator that could lead to…
