Today, wireless sensor networks (WSNs) are finding places in a wide range of applications concerning with remote and mobile measurement, personal tracking also for medical purposes, monitoring of industrial processes, mobile agents and automated warehouses to cite a few. In most of such applications, it is also required to estimate the position of the sensor node or the distances among the nodes....
Nowadays, the matter of uncertainty in face recognition based biometric systems is a relevant issue for the scientific community. This is due to the even more increasing deployment of such systems in critical applications as safety, security and access control, to cite a few. In this context, the authors are engaged in the design of general methods for uncertainty modeling and evaluation aimed at...
In the recent years the possibility theory has been investigated by many Authors in the field of mathematics and engineering. A possibility distribution is, from the mathematical point of view, a generalization of a probability distribution, since it can represent a family of probability distributions. Given a probability distribution, different probability-possibility transformations have been defined,...
The paper deals with modeling and estimation of uncertainty in measurement of power quality (PQ) characteristics by using a virtual measurement instrument. The described virtual PQ analyzer is comprised of National Instruments (NI) analog input modules, NI data acquisition board, personal computer and software in LabVIEW™. The main sources of uncertainty are identified and evaluated. A Monte Carlo...
