This paper presents a Flood Frequency Analysis (FFA), which takes into account the notion of characteristic duration. Instantaneous flood discharge data from Foum El Gherza station is used to develop flood-duration-frequency (QDF) curve, using the so-call... see more

The new methods of acceleration harmonic signal frequency tracking based on estimates ofinstantaneous frequency and phase, are proposed and investigated. Better efficiency of new systems e.g. quicker transient process and bigger frequency range is proved ... see more

The mathematical model of the frequency converter cable branch as a part of the mine section power network with a single phase-to-ground fault is clarified. The model takes into account a discrete nature of the output voltage and power switches commutatio... see more

Pitch period evaluation of speech signal is used in many important applications of speech technology. However, among the existingmethods only some can work in case of non-linear and non-stationary signals. The main reason is that the pitch detection metho... see more

This paper describes a method for measuring of the gradient magnetic field in Nuclear Magnetic Resonance (NMR) tomography, which is one of the modern medical diagnostic methods. A very important prerequisite for high quality imaging is a gradient magnetic... see more

A simplified Voltage Peak Detection (VPD)-based flickermeter based on spectral decomposition is proposed in this paper to detect flicker caused by high-frequency interharmonic components which effect the illumination of next-generation lamps, such as LEDs... see more

Common sound source localization algorithms focus on localizing all the active sources in the environment. While the source identities are generally unknown, retrieving the location of a speaker of interest requires extra effort. This paper addresses the ... see more

Direct Torque Control (DTC) has gained popularity for development of  advanced  motor  control  due  to  its  simplicity  and  offers  fast  instantaneous torque  and  flux  controls.&n... see more

Chainsaws with chipper-type chains are widely used in timber harvesting. While existing research on such saws assumes a continuous cutting process, the objectives of the present study were to determine whether or not that is true, as well as to measure in... see more
