Text attribution and classification, for both information retrieval and analysis, have become one of the main issues in the matter of security, trust and copyright preservation. This paper proposes an innovative approach for text classification using Chebyshev polynomials and holomorphic transforms of the coefficients space. The main advantage of this choice lies in the generality and robustness of the proposed semantical identifier, which can be applied to various contexts and lexical domains without any modification.

The problem related with the optimization of a DWDM-PON can be approached in many different ways. The most cost-sensitive parameter for PON design is the length of optical fiber and, in a lower grade of sensitiveness, the number of distribution nodes, like the AWG employed for channel multiplexing/demultiplexing. The first step for finding the topology which minimizes the network deployment cost is choosing the proper way the users connect to the optical distribution network. One of the facts related with the optical distribution network topology is the users' clustering and the way such clusters connect with each other and with the central office. This paper presents a model for clustering users employing a Voronoi's graph partition. That way the clusters' centers could be linked to each other employing a Delaunay triangulation, which corresponds to the dual graph of the Voronoi partition. Provided that the Euclidian Minimum Spanning Tree (EMST) of the graph linking the clusters' centers is a subset of a Delaunay triangulation, through the use of heuristics it is possible to search the optimal Delaunay triangulation and its correspondent optimal EMST.

The Clinker kiln is the core of the cement production process, which is a heavy infrastructure, where a mixture of limestone and clay undergoes physical and chemical transformations at high temperatures. The process has a very complex non-linear behavior, which hinders its control automatically. This article presents the design of a fuzzy logic-based supervisory system for control tasks upon the Clinker kiln operation [1]. The proposed supervisory system, which has been tested offline in an industrial kiln, uses process variables as the temperature in the burning area, the percentage of oxygen and the back-end temperature, to take appropriate control actions to face operating kiln conditions. The considered control variables in the design are the fuel flow to the burner, the air fan speed and the kiln rotational speed. As a result, the supervisory control system tests showed an improvement in kiln stability and clinker production.

This paper proposes a strategy base on a Population-Based Incremental Learning (PBIL) algorithm to reduce the fuel consumption in hybrid fuel cell/photovoltaic power systems. The strategy is focused on increasing the power produced by the photovoltaic (PV) generator to reduce the fuel needed to supply the load. Such an improvement is achieved by reducing the effect of shadows over the system, which is done by dynamically reconfiguring the connections between the PV modules. In such a way, the proposed PBIL algorithm accelerates the detection of the optimal configuration, in comparison with classical approaches. Finally, detailed simulations are used to demonstrate the efficiency of the proposed solution.

This paper studies the Non-Line-Of-Sight condition mitigation issue in mobile subscriber positioning systems by weighting Time-Of-Arrival measures and applying geometrical restrictions. Particularly, this work departs from a more exact characterization of the signal statistics to achieve weighting factors able to reach a more effective mitigation, and consequently a more accurate mobile subscriber positioning. In addition, restrictions based on the cell geometry are incorporated as a complementary refinement method. Therefore, three new methods with better properties than those taken from the literature and used as reference are introduced. These approaches are evaluated within a realistic simulation scenario.

The classical Robust Control Theory applied to network environments does not consider usual network effects like packet losses in the communication between sensors and actuators. In order to design optimal controllers that consider such conditions, one must rely on the class of models dubbed Markovian Jump Linear System (MJLS). In this paper, we study the H-infinity norm degradation in the presence of a limitation on the allowed number of retransmissions in a multi-hop semi-reliable network. Specifically on this study, we implemented the Hop by Hop transport model and also limited the maximum number of retransmissions per packet. For a particular case, it was possible to design a filter with a global number of transmitted packets of only 17.93% of the packets that would be necessary in full reliable communication, yet guaranteeing the estimated error stability.

Computational intelligence can be applied to solve various engineering problems, where earthquake related issue is one of important research topics, as this natural hazard occurs quite often worldwide every year. In this study, a genetic algorithm based neural network model is developed to improve the reliability of predicting peak ground acceleration, the key element to evaluate earthquake response and to setup seismic design standard. Three seismic parameters including local magnitude, epicenter distance, and epicenter depth, are taken in the input layer for developing the estimation model. Then, two geological conditions including standard penetration test value and shear wave velocity, are added for developing a new model to reflect the site response more adequately. Based on the earthquake records and soil test data from 86 checking stations within 24 seismic subdivision zones in Taiwan area, the results show that the combination of using neural network and genetic algorithm can achieve a better performance than that of using neural network model solely. This preferred model can be extended to predict peak ground acceleration at unchecked sites, and can be applied to check the design standard in building code. This study may provide a new approach to solve this type of nonlinear seismic problem.

The software architecture of smart learning environment can be perceived as an environment that is equipped with various audio-visual objects to capture human motion, utterance and gesture, allowing the teacher to deliver lectures to both local and remote audience through the Internet. The interactive objects in such architectural environment are interfaced with simple navigation, depending on operation characteristics, voice, tactile and visual interaction with the aim to improve Human-Machine Interaction. This facilitates effective data acquisition and statistical analysis, in order to assist in decision making by the participants, as well as, apply them in the process of self-assessment. This paper discusses the design and implementation of integrating hap tic technologies into the architecture of smart learning environment by designing components of service oriented software middleware that defines a common gesture framework, and thus allowing multiple hap tic and gesture peripherals to share a within common protocol, as well as, enabling individual device to work as stand-alone entity.

The combination of ontologies is a necessary activity nowadays. The fast growing of ontologies requires efficient processes to perform integrations. Before of the combination, the ontology comparisons (alignment) allow to have a reference of their similarities. The alignment established among ontologies allows defining individual correspondences between their concepts, based on measures of lexical or structural similarities. Normally the alignment is studied among whole of the concepts of two ontologies. But we could have the alignments from an objective ontology toward several ontologies, and to think in the best alignment for each concept, so a multiple combination of ontologies, in order to get the biggest benefit or enrichment in the objective ontology, can be made. This problem can be approached as an optimization one. This problem is studied in this paper, and we propose to apply the Ants colony algorithm to the process of analyzing the multiple ontology combinations, which is a contribution to the ontology integration processes.

This paper analizes a linear and a nonlinear PID control algorithms for a twin rotor MIMO system (TRMS), which is characterized by its nonlinearity, two degrees of freedom and cross coupling. This work aims to stabilize a TRMS in order to achieve a particular position and to follow a trajectory in the shortest time. Mathematical modelling of helicopter system is simulated using MATLAB/Simulink, the two degrees of freedom are controlled both horizontally and vertically through the proposed controllers. Here is also proposed a novel set of nonlinear-segmented observers for each degree of freedom in order to measure the states required by the nonlinear controller. Followed by a comparative performance analysis of both algorithms in a real TRMS.
