Relays may not perform as intended occasionally due to many complex reasons, which may result in relay misoperation. This paper provides a fast detection scheme for symmetrical fault during power swing based on travelling wave theory and wavelet transform. The implementation of the proposed method is discussed in detail, which covers implementation framework, data requirements, selection of mot...

In this paper an Energy Dissipation Rate Control (EDRC) method is introduced, which could provide stable walking or running gaits for legged robots. This method is realized by developing a semi-analytical pattern generation approach for a robot during each Single Support Phase (SSP). As yet, several control methods based on passive dynamic walking have been proposed by researchers to provide an...

Power swing caused by various disturbances will affect distance relay behavior and may result in relay misoperation. This paper provides a new wavelet-based method for detection and classification of transmission line faults during power swing. The multi-resolution analysis based on wavelet transform (WT) has the ability to decompose the analyzed signals into different frequency bands. With the...

In this paper we propose a novel design of a low power static random access memory (SRAM) cell for high-speed operations. The model adopts the voltage mode method for reducing the voltage swing during the write operation switching activity. Dynamic power dissipation increases when the operating frequency of the SRAM cell increases. In the proposed design we use two voltage sources connected wit...

A game of threats on a finite set of players, N , is a function d that assigns a real number to any coalition, S ⊆ N , such that d(S) = −d(N \S). A game of threats is not necessarily a coalitional game as it may fail to satisfy the condition d(∅) = 0. We show that analogs of the classic Shapley axioms for coaltional games determine a unique value for games of threats. This value assigns to each...
