The article presents an experimental sonar high resolution imaging system capable of producing three-dimensional images of observed objects. The system works in an inverse synthetic aperture configuration with rotating object. In order to achieve a 3-D image the vertical position of the sensor changes during the observation. The architecture of the ultrasonic sensor, simulation as well as experimental...
The highly limited number of observation results in the increase of the prediction errors. In such case the linear Kalman filter (KF) will work within the unsteady state, which can lead to unpredictable results. The paper presents an alternative, simplified methods for the tracked object position prediction with the linearization of the trajectory. The obtained results are compared with the KF predictions...
In 2011, a geophysical survey was carried out in the surroundings of the Jagiellonian University in Cracow, using a Very Low Frequency method. The measurements were designed to determine the reason of frequent flooding of the lowest level of the building. The main objective of the study was to find out from where and in which way the rainwater seeps into the building and how this problem can be solved...
The paper presents a conception of classification method of Visual Evoked Potentials (VEP) to physiological or pathological case based on power spectral parameters. The authors have verified their concept through a series of numerical experiments performed using a dedicated application. As a result of experiments, the final method provided only 4 cases of wrong classification among training data (6%)...
