Abstract This paper presents an alternative to estimate armature circuit parameters of large utility generators using real time operating data. The alternatives consider the use of orthogonal series expansions in general and Hartley series in particular. The main idea considers the use of orthogonal series expansions for fitting operating data (voltage and currents measurements) and/or syntheti...

This paper presents a real-valued discrete multicamer modulation approach that is based on the use of the discrete Hartley transform (DHT) and its inverse (IDHT) to perform the modulation and demodulation operations. Since the DHT and IDHT definitions are identical, we can use the same hardware or program to implement the modulator and demodulator of the proposed multicarrier method. As compare...

The classic Shannon-Hartley law suggests that the achievable channel capacity increases logarithmically with the transmit power. By contrast, the MIMO capacity increases linearly with the number of transmit antennas, provided that the number of receive antennas is equal to the number of transmit antennas. With the further proviso that the total transmit power is increased proportionately to the...

This paper first introduces a canonical representation for cylinders. The canonical representation introduced here is closely related to the Plücker line respresentation. It then drives the general equation of a cylinder using this representation. In this paper, we also show that this representation is an appropriate one for computer vision applications. In particular, it allows us to easily de...

The study of Hartley designed an easy-to-use score to predict mortality in noninvasively ventilated COPD patients. More information about NIV is gained, but the exact measures on how improve clinical practice remains uncertain.https://bit.ly/3tFfg8F
