Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
The growing demand for rapid response to tasks that robotic systems carried out, makes us increasingly think about robust and fast approaches. This paper presents a novel approach based on modeling the task known as Time-to-contact, in order to forecast the time it would take for a robot to collide with a detected object. For this we use an statistical approach based on time series. In addition, the...
This article presents a comparison of two meta-heuristics techniques a) Artificial Bees Colony (ABC), and b) Genetic Algorithm (AG), for path planning problems. To validate the algorithms ten 2D maps were used each with different obstacles number and geometry. Results were compared according to the following measurements: 1) performance time and 2) length of the way. Results of the simulation show...
Artificial Intelligence area has penetrated the medical field with the purpose of supporting the automatic recognition of brain imaging. One of the diseases that has been increasing in the last decade are Brain Stroke, whose set of diseases, affect the cerebral blood vessels. Given that effects that can cause this type of disease, it is important to characterize the sources that generate medical images...
The goal of this research was to determine the brainwave patterns that characterize the movements of a hand. Measurements of the brainwaves of five students were taken using an electroencephalography sensor placed in the frontal lobe; data were collected while participants made a series of repetitive hand movements. The results proved the existence of a characteristic pattern of alpha, beta and gamma...
The start up of a differential wheeled mobile robot is presented here via the use of embedded hardware with free software. The main function of such an embedded hardware is the data acquisition and processing. To this end, predetermined programs of the embedded hardware along with new ones also designed with free software are employed. With the above, in the future, a robot that allows the implementation...
Two-dimensional mapping by unmanned aerial vehicles (UAV) is becoming a wide used technique. This technique is being applied to precision agriculture, 2D inspection, photogrammetry, etc. For all these areas is quite important to acquire the finer spatial resolution as possible. In this paper, we address the problem of computing the configuration of UAV and camera that optimizes the spatial resolution...
In this paper we are interested in knowing, if a filter and a feature selection are used, the action recognition is improved. In the filter phase, Kalman filter and Savitzky-Golay filter are proposed to analyse skeleton acquired by the Kinect, in order to minimize the noise. In the phase of feature selection, the algorithm Reduction of Feature Dimensions based on Standard Deviation (RFD-SD) and Principal...
This paper aims for the transmission of an RGB image mixed with a chaotic signal generated by the Sprott chaotic system which is simulated in Matlab-Simulink. Open-Plus-Closed-Loop is used in order to synchronize the systems from the Sprott's collection, only five cases of Sprott are shown which are known as cases A, B, C, H, and R. These cases were simulated to carry out the transmission of information,...
Magnetic Resonance Imaging (MRI) is an important area in medical enviroment. Many studies base their diagnosis upon what it seems in the images. However, there are critical issues while dealing with MRI; noise sensibility, long acquisition sessions, appearance of artifacts, blurring, etc. One way to counter measure blurring and long sessions is by using Super-Resolution (SR) algorithms. In this work,...
The objective of the study presented in this paper is to discuss the advantages and shortcomings of Hilbert Huang Transform (HHT) over traditional Fourier based methods (Fast Fourier Transform, FFT, and Discrete Wavelet Transform, DWT) in the analysis of Spontaneous Pupillary Fluctuation signals. An experimental example in a selected pupillary record from a healthy university student is given.
This paper presents connection between filtering and control optimal risk-sensitive equations for third degree polynomial stochastic systems with a scaling intensity parameter, multiplying the diffusion term in the state, and output equations, with exponential quadratic cost function to be minimized. The connection is reach through application of separation principle for polynomial systems. In some...
This work presents a regulation control for the “DC/DC Boost converterinverterDC motor” system. Such a control is designed via the Exact Regulation Error Dynamics Passive Output Feedback (EREDPOF). The control validation is carried out through numerical simulations using Matlab-simulink, achieving a satisfactory performance.
