The main objective of this work is the illustration of textual statistical analysis in confronting of the speeches of three great theorists of the world economy; it is aimed to review the emphasis from semantic segments that characterize the speech of each one. In this study, through a correspondence analysis, textual variables from the selected papers were identified, which are presented as characterizing the main concepts that establish patterns in each discourse. The results show the power of this methodology for applications in economics. [ABSTRACT FROM AUTHOR]

A structure of two degrees of freedom permits uniting the controller's design so much for disturbances in the load same as for changes in the reference. In the design of a proportional integral derivative controller of two degrees of freedom (PI-2DoF) it is necessary to introduce conditions of robustness. The present paper proposes a rule of tuning that permits getting the level of robustness in a continuous interval with a smaller error than "± 0.06" of the desired value, surpassing the difficulty of the discreet margins of robustness. The rules was obtained using an adjustment of curves of the controller's optimal parameters, obtained as from the application of the differential evolution optimization's algorithm on a set of representative test's plants of industrial processes. The tuning rules for PI-2DoF control are used to establish the comparison with the rules in literature. [ABSTRACT FROM AUTHOR]

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]

This paper takes as a basis the existence of an Informatics Technological Centre, implanted in a Research Complex, which is based on an architecture of agents and provides users with updated information, mechanisms of alerts and ease in finding information with a proactive behavior. Despite all these facilities provided, this Technological Observatory has lacks of functionalities for monitoring trends and indicators related to research topics. It is proposed to use Business Intelligence elements, such as dashboards, plus social modeling approach and i* to model the Observatory with new functionality to improve support decision making. As a result i* models are obtained where Technological Observatory requirements following a goal-oriented approach are captured. In these models the actors, goals, tasks and resources needed to incorporate elements of the dashboards in the Technology Centre are incorporated following an architecture of agents.

Scheduling problems in educational institutions have a computational complexity that makes it difficult to obtain optimal solutions using exact methods. Thus, heuristic techniques have been used to generate feasible solutions in acceptable computation times. In this paper, we solve the problem of assigning teaching and learning units in the least number of quarters using a population heuristic, Method of Musical Composition. The generated solutions satisfy the requirements and show higher quality than manual-built schedules, so that they are currently being evaluated by the educational authorities.

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 results of statistical analysis of network traffic (in bits per second) from and to one university web server. Statistical analysis allows to know the hourly traffic trends and to establish a baseline for normal behavior. It documents, in addition, statistical goodness-fit tests results and analysis of variance, which provide elements that enhance the definition of the baseline. Finally, the outcomes are analyzed to determine its usefulness as intrusion detection mechanism or situations or behaviors that could suggest anomalies or atypical traffic. [ABSTRACT FROM AUTHOR]

The purpose of this article is to present a reference framework in the models and configurations of agricultural supply chains, specifically in perishables.

This paper is part of an ongoing research which intends to analyze and describe the learning processes involved in the entrance to the computer science degree program at the Faculty of Mathematics, Astronomy and Physics of the Córdoba National University. The research conceives learning as a social, cultural, and historical situated process. In this article we communicate the answers to two questions that arose during the analysis of the data: What is learned during the first year at the degree program? Where is such learning oriented to? [ABSTRACT FROM AUTHOR]

The University of Computer Sciences is responsible for the training of computer professionals as well as for the direct participation in the development of national computerization projects and export commitments as part of the industry. The integration model of formation-production- research processes expresses that students must perform a role in the software development process, linked to a real project. The objective of this paper is to establish a proposal of a methodology that systematizes the process of assigning students to a role. It has as a starting point the recruitment processes in the industry and a model for the comparison and prediction of student's behavior in each role. The methods used were document analysis, systemic method, among others. The analysis of the impact of the results of the methodology is analyzed and discussed. [ABSTRACT FROM AUTHOR]

The adoption of Service Oriented Architectures (SOA) by the companies shows high failure rates, mainly because of the way this paradigm is adopted. Thus, the complexity of this process should be addressed by using the evolutionary approach that maturity models offer. However, the diversity of maturity models makes difficult the selection and implementation of most of them. Taking this into account, the objective of this paper is to carry out a comparative analysis between the most representative maturity models and to determine whether they are sufficient in order to evaluating and planning the adoption of SOA with effectiveness. The inadequacies detected after a comprehensive assessment, restrict the evaluation and planning capacities that these models offer. In order to overcome them and using the international experience gained in this field, it were defined the constructs (principles, elements and structure) that support a more integral maturity model.

This paper describes the methodological aspects of the construction of terminological subontologies within the architecture of FunGramKB. The main hypothesis is that the multilevel model of the Nuclear Ontology in FunGramKB (metaconceptual level, basic level and terminal level) can be connected to a terminological subontology in order to minimize redundancy and maximize information knowledge. One of the features of this subontology is, firstly, its implementation for the creation of a specialized module in the Ontology and, secondly, its focus on deep semantics, in contrast with the vast majority of terminological ontologies, which are based on surface semantics.

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.

Most technical terms in the field of Computer Science are English loanwords. English words are frequently preferred to Spanish terms because of different reasons, for instance, because of linguistic economy. In this paper, we reveal the results of an empirical study about the frequency of use of pure anglicisms. It has been carried out among students of Translating and Interpreting at the University of Las Palmas de Gran Canaria (Spain). The scope of use of lexical anglicisms by individuals in the analysed sample seems to be relatively high, but slightly lower than that of Computer Science students who participated in another preliminary partial study. Those students who provided more words for definitions also suggested more synonyms for the terms, and also used more English terms. [ABSTRACT FROM AUTHOR]

In this paper we discuss a data mining application to profile online users on a newswebsite. Such profiles are then used to target users with personalized content in order to increase the overall number of pageviews generated. The additional pageviews provide extra revenue for the online editor. While the proposed system satisfies the online editor to better monetize their content, in our study, we also provide a sociological interpretation of the produced knowledge base. We consider this to be a quite novel approach where scientists from two very different disciplines (i.e., computer science and social science) combine their effort in order to provide a common framework for interpreting and utilizing the information extracted. Both disciplines benefit from a combined approach. From one side the computer scientists can "tune" their data mining algorithms in order to support the different sociological view of the data. From the other side, the social scientists, can benefit from the additional information provided by the data mining tool as they provide a new insight for their data interpretation.

This paper is part of an ongoing research which intends to analyze the experiences of beginner students of the Computer Science Careers of the Faculty of Mathematics, Astronomy and Physics of the Córdoba National University. During the first year of these careers the desertion level is high and there is an important percentage of students who can't past the exams. Using the situated learning theory proposed by Lave and Wenger (Lave, 1988; Lave & Wenger, 1991; Wenger, 1998) we want to describe the learning process that takes place during the encounter between beginner students just arrived to the university and the faculty community itself. We present a preliminary data analysis describing two analytic categories emerged in this first instance: «student- teacher relations and the legitimacies construction» and «identities construction».
