This article presents a new passive islanding detection technique in MGs that uses locally measured voltage signals at the PoC of DERs. The proposed method distinguishes events from normal/non-islanding conditions by utilizing superimposed harmonic spectra extracted through full-cycle discrete Fourier transform. Our solution utilizes machine-learning-based one-class classifier to define and adj...

All previously proposed threshold proxy signature schemes have been based on discrete logarithms required for a protocol to generate and verify a shared secret among the proxy group. Therefore, it is necessary for the proxy signers to perform many expensive modular exponential computations and communications to obtain and verify a shared secret. Moreover, most of the existing threshold proxy si...

with the increase of communication and financial transaction through internet, on-line signature verification is an accepted biometric technology for access control and plays a significant role in authenticity and authorization in modernized society. therefore, fast and precise algorithms for the signature verification are very attractive. the goal of this paper is modeling of velocity signal t...

We analyze the Jordan-Brans-Dicke model (JBD) of gravity, where deviations from General Relativity (GR) are described by a scalar field non-minimally coupled to gravity. The theory is characterized by a constant coupling parameter, ωJBD; GR is recovered in the limit ωJBD → ∞. In such theories, gravity modifications manifest at early times, so that one cannot rely on the usual approach of lookin...

Signer-Base Intrusion-Resilient (SiBIR) signature schemes were defined in [IR02]. In this model, as in the case of forward security, time is divided into predefined time periods (e.g., days); each signature includes the number of the time period in which it was generated; while the public key remains the same, the secret keys evolve with time. In addition, in SiBIR model, the user has two modul...

Background: Black, Asian and minority ethnic (BAME) communities are disproportionately affected by inequalities in transplant services in the UK. There are some indications from pilot programmes that appeals for BAME organ donors may be more effectively communicated by employing grassroots, community-networking approaches, but such initiatives have not been adequately described or evaluated.
