  • The power of dispersion management for 10-Gb/s and 40-Gb/s systems 

    Grosz, Diego; Agarwal, A.; Küng, A. P.; Maywar, D. N.; Lakoba, T. I. (2006)
    "We review applications and requirements of dispersion compensation that enable highcapacity, long-haul, and ultra-long-haul 10-Gb/s and 40-Gb/s DWDM transmission. We briefly describe their impact on system performance ...
  • RE-SPaM: Using regular expressions for sequential pattern mining in trajectory databases 

    Gómez, Leticia Irene; Vaisman, Alejandro Ariel (2008)
    "In sequential pattern mining, languages based on regular expressions (RE) were proposed to restrict frequent sequences to the ones that satisfy user-specified constraints. In these languages, REs are applied over items. ...
  • Aggregation languages for moving object and places of interest 

    Gómez, Leticia Irene; Kuijpers, Bart; Vaisman, Alejandro Ariel (2008)
    "We address aggregate queries over GIS data and moving object data, where non-spatial information is stored in a data warehouse. We propose a formal data model and query language to express complex aggregate queries. Next, ...
  • Prediction in health domain using Bayesian networks optimization based on induction learning techniques 

    Felgaer, Pablo; Britos, Paola Verónica; García Martínez, Ramón (2006)
    "A Bayesian network is a directed acyclic graph in which each node represents a variable and each arc a probabilistic dependency; they are used to provide: a compact form to represent the knowledge and exible methods of ...
  • Optimizing relationships information in repertory grids 

    Calot, Enrique; Britos, Paola Verónica; García Martínez, Ramón (2008)
    "The Repertory Grid method is widely used in knowledge engineering to infer functional relationships between constructs given by an expert. The method is ignoring information that could be used to infer more precise ...
  • Requirements elicitation in data mining for business intelligence projects 

    Britos, Paola Verónica; Dieste, Oscar; García Martínez, Ramón (2008)
    "There are data mining methodologies for business intelligence (DM-BI) projects that highlight the importance of planning an ordered, documented, consistent and traceable requirement’s elicitation throughout the entire ...
  • Work in progress: programming misunderstandings discovering process based on intelligent data mining tools 

    Britos, Paola Verónica; Jiménez Rey, Elizabeth; Rodríguez, Darío; García Martínez, Ramón (2008)
    "We present research work in progress that focuses on data mining tools used for helping teachers to apply a three step knowledge discovering process to diagnose students’ misunderstandings (and their causes) related to ...
  • Pedagogical Protocols Selection Automatic Assistance 

    Britos, Paola Verónica; Cataldi, Zulma; Sierra, Enrique; García Martínez, Ramón (2008)
    "The preliminary results presented in this paper corresponds to a research project oriented to the search of the relationship between the predilection of students concerning learning style and the pedagogical protocols ...
  • Synthesis of LEB (Linear-ellipsoidal-bounded) regulators and filters for discrete-time systems 

    Antonini, Claudio Daniel (1987)
    "This work is applicable to LTI systems, described by state-variables, whose measurement errors, controls and outputs are to be bounded by upper and lower measurement noises and bounded disturbances. The methodology has ...
  • Real time stable identification: A Nehari/SOS approach 

    García Galiñanes, Rafael; Sánchez Peña, Ricardo S.; Mancilla Aguilar, José Luis (2007)
    Here we present an adaptive identification algorithm based on Second Order section (SOS) model structures. The procedure guarantees stable transfer functions whenever the actual physical plant is stable, due to an optimal ...
  • Development of an optimized LEB filter and its application to INS/GPS test data 

    Antonini, Claudio Daniel (1993)
    "An optimized linear-ellipsoidal-bounded (LEB) filter has been developed and applied to data obtained from a ground test using a combined INS/GPS configuration. In this cascaded configuration, the filter receives eight ...
  • Influence of temperature and interfacial tension on spontaneous imbibition process 

    Chimienti, M.E.; Illiano, S.N.; Najurieta, H.L. (1999)
    “Spontaneous imbibition is a mechanism that can significantly contribute to the production rate and final oil recovery in fractured and stratified reservoirs. This mechanism is affected by rock and fluid properties and it ...
  • Conceptualization maturity metrics for expert systems 

    Britos, Paola Verónica; García-Martínez, Ramón; Hauge, Ødwin (2006)
    “Metrics used on development of expert systems is not a well investigated problem area. This article suggests some metrics to be used to measure the maturity of the conceptualization process and the complexity of the ...
  • An extension of chaotic probability models to real-valued variables 

    Fierens, Pablo Ignacio (2008)
    "Previous works have presented a frequentist interpretation of sets of measures as probabilistic models which have denominated chaotic models. Those models, however, dealt only with sets of probability measures on finite ...
  • Discounting rate: a matter of common sense rather than a theoretical problem 

    Rosbaco, Juan (1999)
    “Different rates proposed by several authors to discount cashflows of given projects are discussed. The paper starts by reviewing what the objectives of an evaluation are and later presents the different discount rates ...
  • Multiple internal rates of return: when to anticipate multiple IRRs and how to take advantage of them to perform a better evaluation 

    Rosbaco, Juan (1999)
    “There are different rules to delimit or exactly determine the number of Internal Rates of Return a project may have or has. These rules show that, when the sequence of signs of the cumulative cash flow vs time function ...
