Abstract

In this work I develop numerical algorithms that can be applied directly to differential equations of the general form f (t, x, x') = 0, without the need to cleared x'. My methods are hybrid algorithms between standard methods of solving differential equations and methods [...]

Abstract

The era of mobile media has placed communications convergence at a new stage. The importance of studies about mobile communications has been growing increasingly over the last years. This growth is connected to the increase in the access to contents through new devices. The last ten [...]

Abstract

A mixed hierarchical approximation based on finite elements and meshless methods is presented. Two cases are considered. The first one couples regions where finite elements or meshless methods are used to interpolate: continuity and consistency is preserved. The second one enriches [...]

Abstract

This paper contributes for the research agenda located at the intersection of processed normative changes and the advancement of new convergent technologies for the Audiovisual Communication Services (ACS) sector. It is based on a systematization of two cases (Colombia and Uruguay) [...]

Abstract

This paper analyzes the educommunicational consequences of the transformations of mediated communication in the process of digitization. We present qualitative empirical evidence on the use of mass media and digital technologies from the digital convergence of media, the industry [...]

Abstract

This article aims to offer the state of the art of international research in online journalism. This work focuses its attention on four of the main features of the field. Three of these comprise the characteristics of digital discourse: hypertextuality, interactivity and multimediality; [...]

Abstract

The introduction of digital technology in the press and communication offices workplace has favoured new skills of labour organization, the distribution of contents though diverse platforms and the labour polyvalency of its members. The new materials are spread rapidly and massively, [...]
