RESUMEN:

Se presentan los resultados obtenidos de aproximadamente 460 experimentos de fallas inducidas de corto circuito entre diferentes vueltas de diferentes transformadores de prueba. Estos se realizaron con la intención de caracterizar los cambios en la corriente del primario del transformador cuando la falla ocurre en el secundario. El objetivo fue encontrar las bases que permitan el desarrollo de un prototipo de reconocimiento de fallas internas en transformadores, para tomar decisiones de mantenimiento que eviten la agudización a nivel crítico de dichas fallas y con esto se coadyuve para evitar que ocurra en el  transformador una falla catastrófica que además del daño en el transformador provoque problemas que se extiendan desde su sitio de instalación y operación atreves de la red, por ejemplo la interrupción del servicio eléctrico en la zona cubierta por ese transformador, más todos los transitorios electromagnéticos producidos durante la falla más drástica. Pues normalmente las protecciones de los transformadores no se ajustan para reconocer fallas insípidas, por lo tanto la falla inevitablemente evolucionara a una de mayor agudeza, hasta que llegue al nivel en que la protección la considere peligrosa, sin embargo el nivel de daño puede ser ya importante para ese momento.

RESUMEN:

ViTiC was designed with the specific purpose to control the attack of a particular nosive fungus that affects the production of wine. In the region of Rias Baixas in Northern Spain, the production is reduced when certain conditions appear: temperature, humidity, wind and the melting pot for the Mildew fungus is prepared. Several academic models have analyzed those conditions and using those tools an automatic system including different sensors was implemented in order to know when to take preventive countermeasures and reduce the fungus effects. Additional benefits of this implementation include: controls for chemicals and fertilizers used in a digital production book, instant alerts and notifications and knowledge sharing among the producers in the region. As direct results of this implementation, production losses have gone down to maximum 5% and costs reduced in 15%.

RESUMEN:

In this paper it is proposed a new symmetric cryptosystem. It will be used to carry out image encryption without compression, in this case, BMP format images. A significant contribution is the use of one elliptic curve with a zero constant to generate a schedule of 15 encryption keys using a solution point of this one. On the other hand, by means of Chaos, it will be generated a permutation and its inverse permutation, both of which will be the same size of the image. The encryption process will be carried out by 14 rounds and it will also use the AES S-Box and logical operations XOR, in order to reach a high randomness level. Finally, it will be applied the Elliptic Curve Integrated Encryption Scheme (ECIES) to accomplish the encryption keys distribution in a secure way. Due to the above, this is a hybrid scheme. The results over RGB and black-and-white images are presented to verify the performance of the proposed algorithm.

RESUMEN:

The focus of the present project was to improve the switching capacity in the control stage of the phototherapy lamp, also achieving to increase the efficiency of the behavior of the power converters of its power supply. Previously said control stage was developed with elements of low response. The improvement was achieved with the implementation of an integrated circuit array: a function generator and a high-speed a high-speed pulse width modulation controller, PWM, circuits capable of generating high frequencies and comparing signals for switching in the order of nanoseconds. With such it was possible to obtain signals that can be adjusted both in frequency and in amplitude. The previous design only allowed a working range of 10 kilo Hertz, and with the implemented arrangement a condition of up to 100 kilo Hertz was achieved, and most importantly, enabled the possibility of making the wavelength modulated in which the lamp operates. The design of the inductors was modified, for its optimization, by means of the equivalent constant model, reducing the losses in the core and in the copper and increasing the performance of the converters. Ensure that the electrical parameters are the required, thus making the improvement in efficiency and characterization. The function generator provided an improvement in the harmonic distortion. Due to the high-speed signal comparator, higher commutation in the converter is achieved, this is reflected in its load, since a more natural sine wave is produced.

RESUMEN:

This work proposes an intelligent automated system for pieces’ recognition and location regardless of their position and orientation in a robotics application. The objective is to implement a system that allows to identify the pieces deposited in a conveyor belt in a manufacture cell. The system consists of 5 stages: image obtaining, preprocessing, segmentation, features extraction and classification. A system tolerant to changes in lighting is proposed in the first three stages, while a comparison between two methods that allow objects to be represented is proposed in the fourth stage: a) Boundary Object Function (BOF) and b) Invariant Moments (IM). The classification stage can be solved in several ways, but in this case a back propagation artificial neural network was used; this technique has noticeable advantages over traditional methods, such as improved accuracy, less overtraining and relatively low computational cost. The results of the tests reported a minimum effectiveness of 90.69% in the networks trained with the IM, while the networks trained with the BOF algorithm as descriptor vector achieved a lower performance that fell to 72.09%.

RESUMEN:

We present an electronic circuit to detect the bifur- cations of the diffusion-less version of the BVAM biological model proposed by Barrio et. al in 1999. These bifurcations are detected as a function of two intrinsic parameters of the model, which are dynamically changed in the electronic circuit by an external voltage signal. This is an important characteristic of the proposed circuit, due to that we can vary in a simple way the parameter values without physically replacing any electrical component. For its part, we emphasize that the analyzed system can exhibit bifurcations cannot be found from a linear analysis. In this sense, the proposed electronic circuit allows finding all bifurcations exhibited by the system because conserves the nonlinearities of the model. To show the  functionality  of  the  proposed circuit, we calculated the Hopf bifurcations by linearizing of the BVAM model and, for another hand, we experimentally detect the same bifurcations using our electronic circuit. The results show that the circuit is able to detect the Hopf bifurcations with good precision.

RESUMEN:

In this paper we analyze the similarity in images of natural scenes with changes in scale and illumination. The similarity is evaluated from the application of structural metrics CW-SSIM (Complex-Wavelet Structural Similarity) and STSIM (Structural Texture Similarity Metric). These metrics incorporate structural information in the comparisons of images based on local statistics. Similarity metrics require a series of steps for their application. First, a sub-band decomposition process is performed, then descriptors are extracted, comparison formulas are applied and a joining strategy is applied to obtain a total similarity value. Finally, in the analysis of the results, a general average of the values was made for each level of scale and illumination, the standard deviation and the processing time for each similarity metric were calculated. The results indicate that the STSIM metric is more advisable to evaluate the similarity of images of natural scenes with changes of scale and illumination.

RESUMEN:

Today, power utilities are integrating intelligent sensors and advanced communications into their distribution systems that go beyond substations to include downstream feeder intelligent electronic devices (IEDs). This integration of advanced technologies provides several benefits. It increases system efficiency and cost-effectiveness, and it improves reliability, power quality, and resiliency. It also enables easy integration of new technologies such as renewables, energy storage, and plug-in electric vehicles.

Reliable two-way communications and sensors enable advanced distribution automation (DA) applications that require minimal human interaction. This paper describes applications of DA, with a focus on emerging communications technologies and advanced line sensors that provide distribution utilities faster fault detection, isolation, and restoration. It also describes communications sensor network architectures and how these sensor networks integrate into the existing utility infrastructure to provide insights into the distribution system. The essential requirements of these communicating sensor networks, including energy harvesting, accuracy, and cybersecurity, are covered in detail. The paper also shows how sensor networks, when combined with communications technologies, can improve reliability indices like the System Average Interruption Frequency Index (SAIFI), the Customer Average Interruption Duration Index (CAIDI), the System Average Interruption Duration Index (SAIDI), and the Momentary Average Interruption Frequency Index (MAIFI) for distribution utilities.

RESUMEN:

Many power utilities cannot afford to provide private fiber or wireless-based communications to every substation or remote facility. To support communications-assisted protection schemes at sites without private networks, these utilities historically leased analog communications circuits from carrier phone companies. Thousands of substation sites across North America rely on the predictable and guaranteed performance of analog leased phone lines to run critical power protection circuits. However, national carriers plan to discontinue support for analog-based circuits over the next few years to encourage the migration of power protection services to digital Ethernet-based circuits. At this time, DS1 pseudowire technology is the standard telecommunications solution for converting analog circuits to packet-based services. This presents a challenge for many utilities. Without a change in approach, power utilities face significant end equipment upgrade costs, and protection performance will be compromised for circuits that currently rely on analog leased lines. This paper presents a new solution to the migration challenge that enables a utility to preserve existing analog end equipment, create a low-latency circuit through a leased Ethernet service, and maintain end-to-end communications-channel performance for critical applications such as teleprotection. This solution is based on a technology called virtual synchronous network (VSN). VSN technology was originally developed to preserve the performance of time-division multiplexing (TDM) when transporting teleprotection circuits across private core networks based on either Multiprotocol Label Switching (MPLS) or Carrier Ethernet. This paper also summarizes an extended field trial created by the utility Consumers Energy and analyzes the end-to-end latency performance of a direct transfer trip (DTT) scheme over a leased Ethernet service. The results show that a VSN can be used to improve the latency performance of a leased Ethernet circuit and provide an economical migration path from analog to Ethernet, avoiding the need to upgrade a utility’s end equipment.
