Introduction: This work analyzes the introduction in Spain of the first systems of production and television broadcasting based on computer files technology, also known as MAM (Media Asset Management). The establishment of the different MAM systems as a digitization, has meant the replacement of the technology based on video tapes, due to the obsolescence of this system. Methodology: This work also establishes a parallelism in the MAM digitization between CNN (Atlanta, USA), Telecinco-Spain and Telemadrid-Spain. Results: this study seeks to gather information on the consequences of the change in the workflow on television that MAM digitization carries with it. Discussion: Implementation of MAM technology has meant a profound transformation of the basic processes of the production system in television. Conclusions: this paper deepens on the labor transformations of the different jobs that involved the adoption of the first MAM systems in the three television stations analyzed CNN (Atlanta-USA), Telecinco-Spain and Telemadrid-Spain.

The flexibility of spectrum usage required by emerging paradigms, radio spectrum demand driven by new wireless technologies, new applications and government policies oriented to massive use of Internet require spectrum management authorities to have smarter tools to do their work in an efficient way. This paper presents the design and implementation of a web application to support spectrum management activities using constraints programming. The design includes a mathematical model for allocation constraints, a mathematical model for interference constraints, a relational database of the National Allocation Table considering bands, channels and services associated with geopolitical division of Colombia, and an operator allocation database. These tools allow creating and to parameterize different levels of restrictions establishing different costs and weights. The interference analysis module takes into account the geographical location and technical characteristics of transmitting stations. The tool developed in this work can be used, among others, in allocation optimization studies, assessing policies of spectrum reallocation, allocation analysis to maximize specific criteria, reducing technology costs of implementing specific technologies and help identifying objective variables for spectrum price estimation. To facilitate the understanding and exploitation of the application several didactic examples are included. [ABSTRACT FROM AUTHOR]

Formal specification is an active research field in software engineering of this century, where different configurations and techniques are employed and although their industrial use is still limited, the scientific community currently has a different understanding about its usefulness and necessity. Until present time, researchers' work focuses on the specification written during the design of the preliminary functional model, for this reason it mainly focuses on evaluating the related tools. In this paper, a literature review is performed, covering the essence, function, use and disadvantages of formal specification techniques and some assessment and evaluation criteria are analyzed regarding their weaknesses. The results become the basis for future work formulation, aimed to the strengthening of formal specification as a core research activity. [ABSTRACT FROM AUTHOR]

This paper presents the use of clustering techniques to segment license plates through a method applicable to systems ANPR (Automatic Number Plates Recognition). To achieve this goal were different tests with clusters, comparing its performance and effectiveness. This method uses clustering techniques to remove automatically, spurious points that can be generated by the correlation techniques. To perform segmentation of license plates, the method receives as input a cloud of points corresponding, resulting in a matching between the input image descriptors SIFT (Scale Invariant Features Transforms) and the reference image descriptors SIFT that contains the possible characters of a license plates. Through clustering techniques, gets the cluster consisting of the points located in the zone of the plate and also his associate centroid. Regions growing technique is then used to segment the minimum area that encapsulates the centroid which constitutes the patent plate of the considered image. In conclusion, we present a clustering process that is part of a hybrid approach that combines techniques from computational vision and intelligence, to segment license plates in external environments.

Although natural language processing can be deemed as a discipline between applied linguistics and artificial intelligence, theoretical linguistics has played a remarkably minor role in this field of research. One of the goals of this paper is to portray the reasons of the failed symbiosis between linguists' research and that of computer scientists, where probabilistic approaches haven been steadily overshadowing linguistic models. In spite of this discouraging scenario, FunGramKB, a knowledge base particularly designed for natural language understanding systems, serves to illustrate how a language-aware and cognitively-plausible approach to human-like processing can contribute to the development of enhanced knowledge-engineering projects.

The didactic study of the students of Computer Engineering is at the present time an imperative starting from the necessities of the country. To form students for concrete tasks of teach is object of elaboration of different strategies in the country. The strategy of didactic studies of the Ability of Computer science of Matanzas understands the integration of the labour, an academic and investigative component that prepares the students from the first year of the career until the fifth year to face the Computer Sciences teach. In this strategy they play a fundamental paper the year communities in the coordination of the methodological work and of tutorship to the students and the student's fifth year-old assistants mainly in the formation of the students of years first and second [ABSTRACT FROM AUTHOR]
