This paper presents an application of a time-delay neural networks to chaos synchronization. The two main methodologies, on which the approach is based, are time-delay recurrent neural networks and inverse optimal control for nonlinear systems. The problem of trajectory tracking is studied, based on the Lyapunov-Krasovskii and Lur'e theory, that achieves the global asymptotic stability of the tracking error between a delayed recurrent neural network and a reference function is obtained. The method is illustrated for the synchronization, the analytic results we present a trajectory tracking simulation of a time-delay dynamical network and the Chua's circuits.

In this communication we explain how a Support Vector Machine (SVM) can be applied to compute the Euler number or Genus of a 2-D binary image. By taking into account the results provided by a mathematical formulation that is known producing exact results we derive two specialized SVM-based architectures, one useful for the 4-connected case and one useful for the 8-connected case. We validate the applicability of both architectures with two sets of images and compare their performance in terms of processing times with several standard methods reported in literature.

It is modeled diagnosis and treatment for cerebrovascular diseases by partially observable Markov decision processes. It is desired that this model will be helpful for physicians without adequate experience for the treatment of such diseases. Patients with cerebrovascular diseases need immediate treatment to prevent disability from irreversible neuronal damage or even death. Information used in this type of modeling comes exclusively from neuroimaging. Our starting results encourage us to continuing this research.

The climatic chambers are enclosures that provide a desired climate regardless of the outside environment. They are frequently used in research and industry, durability testing of materials, devices or appliances. FIME-UANL developed a climatic chamber, it is located in the climate-controlled laboratory. This climatic chamber has the facility of electronic expansion valve (EEV), electronic hot gas valve bypass (EHGB), pressure regulating valve (EPR). The goal of this work is to develop and implement control algorithms, that to improve the performance of the cooling system of the climatic chamber without compromising its performance in terms of accuracy and stability. In addition to assessing the energy performance through the pressure ratio due to the use of control strategies in the cooling system of the climatic chamber using cooling system COP and pressure ratio as a comparator.

This paper presents the design methodology of a complete digital pre-distortion system that enables the power amplifier linearization. This system employs the memory polynomial model for its realization. The performance of the linearization is validated by using an LTE carrier signal in the band of 10 MHz. This integrated solution is capable of linearizing any real power amplifier from measurements of AM/AM and AM/PM conversion curves. Furthermore, this development test bed is able to predict the behavior and facilitates the design analysis of a pre-distorter. The experimental results are implemented employing a DSP-FPGA by using DSP Builder tool to obtain the VHDL hardware description. The proposed model shows a spurious-free dynamic range of 50 dBm and an adjacent channel power ratio reduction of 25 dBc for the NXP 10W power amplifier.

Currently, many applications require following objects through a sequence of images. Typically, the motion is estimated by calculating the optical flow on monochrome images because it involves fewer computational cost. However, sometimes the intensity of the pixels may not be sufficient to successfully achieve the objective of identifying moving objects. In this paper, it is proposed to use models of color, as RGB and HSV, for motion estimation method using the Lucas and Kanade method of calculation of optical flow, to improve motion estimation. As part of our contribution, it is also proposed a metric to measure the goodness of the results in order to evaluate the reliability and accuracy of optical flow calculation in each method. Finally three scenarios with different characteristics are presented to evaluate the results under different conditions.

This paper discusses possible communications requirements that emerge from the necessity to connect Internet of Things (IoT) devices, and explores the possible utilization of the 30 to 90 GHz spectrum band(the lower EHF band) to establish Wireless Device Area Networks (WDAN) between all the devices that are close by. While the lower EHF band has already been set as the cannel to create Wireless Personal Area Networks (WPAN), the band is not being used widely for such purpose, nor have the corresponding standards been updated to the latest technology trends. The EHF band is a very valuable portion of the spectrum that is not being exploited at its best potential, and surely could be considered as an alternative to provide emerging IoT devices with an exclusive channel to establish their own, device to device, direct communications.

This paper aims on three different behavioral models with memory for radio frequency power amplifiers. These models are based on the principle of Volterra series, which were simulated in the Matlab-Simulink environment and implemented on a DSP-FPGA Altera Stratix III board. The MPM, Hammerstein and Wiener models were compared based on the distortion curves AM-AM and AM-PM of a RF-PA 10W through different levels of nonlinearity and memory depth. The results show the metric NMSE in the range of -30 dB for the three models of a NXP 10W GaN HEMT @ 3.0 GHz PA demonstrating its high accuracy during the FPGA implementation.
