Nowadays, the interoperability between e-commerce sites requires that information must be processed syntactically and semantically. For example, find the best product in two different sites according to different criteria, including numerical and non-numerical attributes (e.g. product name, price, product evaluation, customer opinion, etc.). We present a mashup between the sites eBay and Amazon to search for products according to these criteria. The integration is driven by ontology with a syntactic-semantic process. The result is the best product of the two sites according to criteria (price, user rating, delivery times and geographical location). Additionally, a map is displayed, showing the product information, not only the data related to the product, but also other geographical locations where is possible to buy products and opinions from other clients. Tests showed that including semantic processes in the product search gives better results than when using only syntactic processes.

This paper reports on the application of a custom-designed electronic nose (e-nose) for the detection and screening of pesticide residue from vegetable samples, together with a discussion of the analysis performed using two different data-recognition algorithms. Chilli samples were provided by the Agri-Food and Veterinary Authority Singapore, with different concentrations of a known pesticide named profenofos. The e-nose system used in this experiment was made up of 7 different types of Figaro sensors. Principal Component Analysis (PCA) and Fuzzy C Means (FCM) techniques were used to analyse the sensor responses obtained in the experiment. Unlike other previous methods based on multi-residue analysis, the e-nose technique here described does not require of gas chromatography techniques nor controlled laboratory conditions, and the results can be obtained within minutes. The results of the experiment show that the e-nose was able to detect and classify the different chilli samples when either data-recognition method was used.

A pole placement method was applied in feedback control of an intelligent flexible beam. Finite element techniques were used for the discretization of the continuous beam, and from the corresponding state space representation, control gains were obtained by the pole allocation method for the appropriated modal control. The results obtained show that control of the first two vibration modes is successfully accomplished with a single input control.

In this paper, we propose a complete closed-form solution to the inverse kinematics problem for a 5-dof manipulator robot, where the existence conditions for all the possible solutions are clearly established and the "singular configurations" where infinite solutions exist are identified. We define a "desired configuration" for the final effector as the position for the center of the gripper and the direction of the gripper's main axis. This choice seems natural for robots mainly devoted to assembling tasks, even if the rotation around this main axis cannot be freely set. Under these conditions, a straight-forward method in order to obtain all the different exact solutions is also presented.

In this work we propose a Choice Function for guiding Constraint Programming in the resolution of Constraint Satisfaction Problems. We exploit some search process features to select on the fly the Enumeration Strategy (Variable + Value Selection Heuristics) in order to more efficiently solve the problem at hand. The main novelty of our approach is that we reconfigure the search based solely on performance data gathered while solving the current problem. We report encouraging results where our combination of strategies outperforms the use of individual strategies.

Renewable energy sources have focused a special attention in wind energy conversion systems, where the goal is maximal power extraction. This paper presents an evaluation of the linear controllers eigen structure assingment, linear quadratic regulator, and the robust loop shaping design procedure actuating on a small wind energy conversion system with a permanent magnet synchronous generator, the rectification is made by a diodes bridge, and the direct current is controlled by a DC-DC converter. The analysis is made calculating the mean square error of the optimal tip speed ratio and the tip speed ratio developed by each regulator, the numerical results also show the performance of the power coefficient, power extracted from a wind profile, and the operation around the optimal regime characteristic. The proposed system works under variable wind speed, and validate the methodology applied.

This work addresses the problems of (i) self-calibration of a moving camera observing a 3D scene composed by planar structures and (ii) scene segmentation and reconstruction. Although there exist some works intending to deal with these problems, most of them are based on the estimation of the epipolar geometry, non-linear optimization, or linear systems that do not incorporate geometrical consistency and may produce undesirable side-effects. In this paper, we propose a novel iterative linear algorithm that exploits the geometrical and algebraic constraints induced by rigidity and planarity in the scene. Instead of solving a complex multi-linear problem, we solve iteratively several linear problems: coplanar features segmentation, planar projective transferring, epipole computation, and all the plane intersections. Linear methods allow our approach to be suitable for real-time localization and 3D reconstruction, e.g. for autonomous mobile robots applications. Furthermore, we avoid the explicit epipolar geometry computation and all the stability problems commonly associated with it.

This article presents the experimental verification of kinematic and dynamic models of the PHANToM Premium 1.0 haptic device [2]. Dynamic properties are evaluated [7], in order to apply nonlinear control techniques and evaluation of manipulability and energy in real-time. Position kinematics and differential kinematics are validated for the trajectory planning by using joint control techniques for local haptic guidance and kinematics and dynamics operated control methods for virtual man-machine interaction (haptic interface).

The underwater vehicle control has two problems to deal with; parametric uncertainty and unknown disturbance. Sliding Mode Control (SMC) effectively addresses these issues and is therefore a viable choice for controlling underwater vehicles. On the other hand, this method is known to be susceptible to chatter, which is a high frequency signal induced by the switching control. In this paper a new control methodology called Model-free High Order Sliding Modes Control (HOSMC) is introduced. HOSMC principal characteristic is that it keeps the main advantages of the standard SMC, removing the chattering effects, this advantage is achieved without model knowledge. Real time experiments in a 1 DOF (Degree Of Freedom) underwater system are conducted to show control effectiveness. Finally, a comparative study regarding PID control and conventional SMC is given.

In this paper we present a robust image watermarking method against geometric distortions and several attacks of signal processing. Initially, the original image is normalized and the feature points are then extracted. Furthermore, the locally most stable feature points are obtained and used to generate several non-overlapped circular regions. Texture-based image block classification in Discrete Cosine Transform (DCT) domain is also used to get watermark imperceptibility. The watermark is embedded and extracted into classified regions using the DCT domain. In the detector stage, the watermark can be obtained without the original image. The experimental results show the watermark robustness against geometric distortion such as rotation, scaling and various other Affine Transformation, and common signal processing attacks, such as JPEG compression and noise contamination.
