Spiking neural networks are designed for better modeling the natural neural tissue physiology in order to increase the biological plausibility of the artificial neural structures. In this paper we will present a simple structure of electronic spiking neurons that is able to model the classical conditioning starting from the Pavlov observations of the dog's central nervous system. For modeling the...
Ballistocardiography (BCG) is a non-invasive method based on the measurement of the human body motion occurring due to acceleration of blood as it is ejected and moved in the large vessels at each cardiac cycle. The system presented in this paper is designed to measure the reaction force of systolic contraction of the body after determining the pumping of blood into the aorta and pulmonary artery...
Spiking neural networks are designed for modeling the natural neural tissue physiology in order to increase the biological plausibility of the artificial neural structures. The best option to obtain real time response of spiking neural networks is to implement the artificial neurons in analogue hardware. Despite the fast operation, a disadvantage of analogue spiking neural networks is the difficulty...
The paper analyzes a variable common mode voltage injection technique for multi-phase sine wave pulse width modulation with improved computational efficiency compared to the Space-Vector Pulse Width Modulation (SVPWM) technique and fewer level switchings in the power inverter, which still achieves similar modulation and control performance in the case of two level voltage source inverters. Also, a...
This paper describes a method for controlling a solenoid-operated valve (SOV) so that it can detect mechanical vibrations or shocks (accelerations, in general). This feature can be an important safety measure since SOVs are often used in complex systems that contain, for example, dc motors. In case of too large perturbations it becomes possible to issue a stop command. No dedicated sensors are used,...
This paper describes a method of converting floating-point expressions into equivalent fixed-point code in DSP software. Replacing floating-point expressions with specialized integer operations can greatly improve the performance of embedded applications. This is a new method that is developed for Direct-Form I filters with constant coefficients and input variables whose low/high bounds are known...
