Nowadays the digital problems, such as copyright violation and content alteration, have been grown. To solve these problems, many watermarking based schemes have been proposed, however most of them address to solve one of these two problems. This work shows a way to embed the watermark for both purposes: copyright protection and content authentication. The main scheme is based on a self-embedding algorithm which generates the watermark sequence from the original image using halftoning method. The halftone watermark image furthermore is watermarked modifying their pixels to embed logotype related to the owner’s copyright; and the watermarked halftone image is embedded for content authentication using Quantization Index Modulation (QIM) in the Integer Wavelet Transform (IWT) domain.

The number of users of mobile devices has increased enormously over the past five years. Along with this, the public concern about how to make sure personal information remains private and safe has also grown, and it has become a high priority standard for mobile device producers to fulfill. Programming languages, by themselves, offer a limited safely, unfortunately. A common example is the use of credit cards, where the credit limit can never be exceed since the programming language cannot guarantee. The authors identify the need to structure the knowledge involved during the process of mobile devices safety development as a crucial step to guarantee trust between users and producers. The proposal project consists on creating a representative model between users and mobile device producers called Onto Device Trust. This model is based on ontologies where knowledge and information are structured on classes and concepts. The ontologies involved in this representative model are: Languages, Tools, Safeties, Industries, Smart Cards, Mobile Devices, Applications, Certificates, Evaluations, Clients, Analyzers and Testers. The evaluation of the ontology content in the Onto Device Trust model is carried out through a technical judgment of the ontology and its associated conceptualization.

Computer vision imply several morphological and mathematical process. Image compression requires methods which involves algorithms and image processing techniques. AHBE system (Algorithm of Huffman combined with Bit Extraction method) provides a novel method to image compression when high quantity of light is present. Preprocessing images is useful in robotics applications to avoid noised data providing relevant information and normalized vector of data. Hoffman algorithm is a greedy technique that is combined with Bit Extraction technique that improves bright and contrast for images obtaining an image equalization in a novel way compressing binary pixels code.

Micro alloyed steels mechanical properties can be modified by nano-modification based on aging heat treatments inducing different levels of nano precipitates on their surface microstructure. Under sour corrosion, electrochemical impedance spectroscopy (EIS) technique could serve to identify the modified micro alloyed steel corrosion properties. This paper present a predictive model for EIS-Ny quist curves using artificial neural networks (ANN) of micro alloyed steels under sour corrosion. For the ANN, an approach based on Levenberg–Marquardt learning algorithm, hyperbolic tangent sigmoid transfer function, and a linear transfer function was used. The model takes into account of the variations of the real impedance, time and steel exposure temperature. The developed model can be used for prediction at short simulation times illustrating the utility of the ANN. On the validation data set, the simulations and the theoretical data tests were in good agreement with R2 > 0.98 for all experimental databases. These results suggest that ANN may play a key role in making lifetime predictions for components based on laboratory measurements.

The system-on-chip of study is a proposed CMOS Image Sensor (CIS) architecture which includes: passive pixel array, digital switches for rows/columns and a first-order single-bit Sigma-Delta Modulator for every four columns. This paper presents the behavioral model of the Sigma-Delta Modulator, to estimate their performance in terms of Signal to Noise Ratio and Dynamic Range. The model starts with an ideal modulator, and then are added noise sources and nonlinear distortions, arose by the light source and the modulator non-idealities. All modeling was developed at system level. The performance obtained with the compartmental model showed good agreement with the temporal measurements obtained directly from CIS. This model allows determining the main noise sources that degrade the performance.

Fluctuations in the level of a physical model of a continuous casting mold were studied to determine the structure of the oscillations in the molten steel level. A water model of one third of scale of an actual continuous casting machine with a perfect control configuration was used in experiments. The liquid level in the mold is measured by recording at high-speed the level fluctuations and then detecting the edges on each of the recorded images. In this work, the Sobel operator was employed. The results show that level fluctuations inside the mold have a complex structure that is repeated in large time periods.

Today, it is common the use of a static power converters to adapt the available energy from a clean source to feed an electrical load. Wind energy conversion systems have become one of the principal areas of research on renewable energies. This research has permitted the development of different topologies and control strategies of power converters to be used on wind energy extraction. This paper presents the design and simulation of a predictive current control algorithm of an AC/DC/AC power converter in order to obtain constant voltage and frequency at variable wind speed, with the advantages of easy and time equidistant implementation on a DSP-based system. Moreover, the proposed system works by using a wind turbine directly connected to a permanent magnet synchronous generator In order to reduce mechanical loss and cost due to a gearbox. Several simulated results at different operating conditions show the effectiveness of the proposed control scheme.

The development of microelectronic industry has been related with the development of methodologies for detection of faults, either in production lines or in the field of action of devices. This has not happened in the industry of micro electromechanical systems (MEMS), which have made great progress in developing device but the fault detection techniques have been inherited the microelectronic. This presents a major problem since the nature of failures in MEMS is radically different from microelectronic failure. Given the complexity of fault modeling MEMS multi physics propose the use of neural networks as classifier system failures that could be implemented in systems self-test or verification in production line for these devices. Defective Comb Drive is detected by neural networks using as an input the resonance frequency and the gain.
