In the present paper, an electronic prototype designed to acquire electrocardiographic signals from marine mammals has been developed. The system consists of a portable device that allows the on-line acquisition of EKG signals through a parallel port interface that is connected to a laptop computer. The EKG waveform, the voltage level, the bandwidth and the(More)
The aim of this paper is to illustrate the structure of X‐farm, a model to manage farming systems under energetic, economical, ecological perspective, using the dynamic simulation approach. The farm is targeted to achieve the energetic self‐sufficiency, by using a quota of the total biomass produced in farm for the production of energy as oil, biogas or(More)
This article presents a practical implementation of an ECG compression algorithm using a Max-Lloyd quantizer, to optimize the low resources of an ECG acquisition and transmission system (telemetry system) for dolphins and human divers. The algorithm scheme is based on a first-order differential pulse code modulation (DPCM) and uses a Max-Lloyd quantizer to(More)
