The modeling and analysis of electric power disturbances affecting power quality has emerged as an important field in the changing electric power industry. These disturbances differ in characteristics, and their occurrence can be attributed to various reasons. Tools capable of classifying these disturbances have been investigated and many are under development. This paper illustrates the harmon...

In order to achieve full binaural sound, audio signals must be synthesized using specialized digital filters characterized by their so-called Head-Related Impulse Responses (HRIRs). They represent the modification to sound due to the listener’s torso, shoulders, head and pinnae, or outer ears. Conventional methods of measuring individual HRIRs require the use of expensive and cumbersome equipme...

A method for identification of a synchronous generator is suggested in this paper. The method uses the theoretical relations of machine parameters and the Prony method to find the state space model of the system. Such models are useful for controller design and stability tests. The proposed identification method is applied to a third order model of a synchronous generator. In this study, the fi...

A novel strategy to the development of digital pole-zero approximations to fractional-order integrators and differentiators is presented here. The scheme is based in the signal modeling techniques applied to deterministic signals, namely the Padé, the Prony and the Shanks methods. It is shown that the illustrated algorithms yield good results both in the time and the frequency domains. Moreover...

Laterally periodic resonators, which can be constructed by use of transversely periodic phase- or amplitude-modulating elements in a cavity, are proposed for stabilization and generation of transversely coherent output from large-area gain. Lasers with periodic resonators have the combined features of conventional cavities and laser arrays. Significant low-order transverse modes and mode discri...
