We present a brief study of compound systems of dierent It is shown that the detailed dynamical studies of massless and massive particles can hardly be associated to standard averaging techniques.

Nuestro objetivo es presentar sistemas, tecnológicamente importantes, que operen como futuros electrocatalizadores en la detección de contaminantes o en celdas de combustible. Así, nanoelectrodos de Pd/Ti, se aplican ...

The goal of this paper is to describe the potential of a visual interface applied to a Nikon 6B/6D autocollimator in order to replace human operator within a laboratory grade measurement. The optical interface implemented ...

We present some new geometries with spheroidal symmetry, with and without mass, that involve new kind of energy momentum tensors, and which are suitable for the description of dark matter phenomena.

This paper presents a multimodal corpus of spoken human-human dialogues collected as participants played a series of Rapid DialogueGames (RDGs). The corpus consists of a collection of about 11 hours of spoken audio, video, ...

Polymer matrices with well defined structure and pore sizes are widely used in several areas of chemistry such as catalysis, enzyme immobilization, HPLC, adsorbents or controlled drug release. These polymers have pores in ...

Satellite and ground network observations of lightning flash distribution data are used to examine the diurnal cycle of lightning activity over the tropical and subtropical regions of South America. The results show in ...

Based on eight years of lightning data (from January 2005 to December 2012) from the World Wide Lightning Location Network (WWLLN) we describe the spatial distribution and temporal variability of lightning activity over ...

In recent decades, many studies reported magnetism in carbon-based materials. This phenomenon was attributed to structural defects within the sample. Many authors showed an increase of magnetization in HOPG (Highly Oriented ...

Associating a license to data is a fundamental task when publishing data on the Web. However, in many cases data producers and publishers are not legal experts, and they usually have only a basic knowledge about the possible ...
