Background and Purpose
cAMP plays an important role in the transduction of signalling pathways involved in neuroprotection and immune regulation. Control of the levels of this nucleotide by inhibition of cAMP‐specific PDEs such as PDE7 may affect the pathological processes of neuroinflammatory diseases like multiple sclerosis (MS). In the present study, we evaluated the therapeutic potential of the...
Early detection of faults in power lines allows improve the service quality and therefore a reduction in high operating costs that a failure of this type implies. This paper describes a method used to determine the type of failure occurs in a three-phase over time, using tools as Hilbert transform and fuzzy classifier for successful detection is done. The algorithm developed uses each of the power...
The use of Artificial Neural Networks with different type of configuration has enabled to develop many applications with higher complex degree. This paper presents an implementation example of noise canceller using Adaline Network for evaluation of performance when change different parameters in audio acquisition, also an analysis of synaptic weights to evaluate the performance of adaptive filter...
In the world, the human robots being a important part in the relationship between human-machine. In this context, a study and design to implementation of a biped robot that is focused in a mathematical modeling and analysis of direct and kinematic, using matrix techniques proposed by Denavit and Hartenberg (DH). In the first part only legs are implemented using digital servos motors without feedback...
Previous works in analysis and design of biosignals acquisition have been done in Universidad Politécnica Salesiana, In this context, this paper presents the results of implementation process of biosignals acquisition lessons with Biopac MP45 by undergraduate students. For each biosignals a protocol acquisition are proposed to safety. Different implementation lessons about in Electromyography (EMG),...
This paper describes a basic experiment about linearization of a second order system as a mass spring damper structure, the mathematical model of system is obtained with characteristics of physical components, the linearization of system is made with acquired signal of a no lineal sensor and getting a new lineal equation, for validation of process a simulation with all components is made. In implementation...
The use of artificial neural networks has enabled applications that would be impossible to achieve with conventional electronics, through to versatility that them have, they can be configured as needed and use as required such as classifiers, adaptive filters, controllers and predictors. This paper describes a experimental implementation of virtual speed sensor for DC motor using back-propagation...
