The purpose of this study was to compare the effect of eight weeks of aquatic and land plyometric training on leg muscle strength, 36.5 and 60 meters sprint times, and dynamic balance test in young male basketball players. Eighteen young…

For a mobile robot that interacts with humans such as a home assistant or a tour guide robot, activities such as locating objects, following specific people, and distinguishing among different people are fundamental, yet challenging robotic vision tasks. For complex…

An analytical approximate technique for conservative nonlinear oscillators is proposed. This method is a modification of the generalized harmonic balance method in which analytical approximate solutions have rational form. This approach gives us not only a truly periodic solution but…

Can you imagine a useful task you would like a social robot to perform for you? This paper presents an Internet survey where participants were asked this question to identify applications for social robots. The applications mentioned by the participants…

The Data Warehouse (DW) design is based on multidimensional (MD) modeling which structures information into facts and dimensions. Due to the confidentiality of the data that it stores, it is crucial to specify security and audit measures from the early…

El Espectador sevillano, redactado por Alberto Lista, se publicó en Sevilla del 2 de octubre de 1809 al 29 de enero de 1810. Aunque se trata de uno de los periódicos más importantes del momento, se le ha estudiado poco.…

The second-order harmonic balance method is used to construct three approximate frequency-amplitude relations for a conservative nonlinear singular oscillator in which the restoring force is inversely proportional to the dependent variable. Two procedures are used to solve the nonlinear differential…

Open societies are situated in dynamic environments and are formed by heterogeneous autonomous agents. In order to ensure social order, norms have been employed as coordination mechanisms. However, the dynamical features of open systems may cause that norms loose their…

Purpose: Citations received by papers published within a journal serve to increase its bibliometric impact. The objective of this paper was to assess the influence of publication language, article type, number of authors, and year of publication on the citations…

Seventy-five years ago, Walter Benjamin showed us that the line between "production" and "reproduction" had begun to blur. Reproduction was no longer optional, consequential and degrading (the shredding of the original’s aura), but was instead being transformed into a principle…
