This paper is devoted to blind deconvolution and blind separation problems. Blind deconvolution is the identiication of a point spread function and an input signal from an observation of their convolution. Blind source separation is the recovery of a vector of input signals from a vector of observed signals, which are mixed by a linear (unknown) operator. We show that both problems are paradigm...

In a proxy signature scheme, a potential signer delegates his signing power to a proxy, who signs a message on behalf of the original signer. In a blind signature scheme, the signee cannot link the relationship between the blind message and the signature of the chosen message. That is, the signee cannot make a linkage between the blind signature and the identity of the requester. Therefore, it ...

Scientists observe, discover, justify and eventually share their findings with the scientific community. Dissemination is an integral aspect of discovery, since discoveries which go unnoticed have no or little impact on science. Today, peer review part this process dissemination as it contributes proactively to quality a article. As numbers journals articles published therein are increasing ste...

Purpose: This paper reviews the studies on balance in blind. Methods: The comprehensively reviewed blind from following databases: PubMed, MEDLINE, Web of Science, ScienceDirect, Cochrane Central Register Controlled Clinical Trials, Google Scholar, and Scopus, 2001 to 2019. Also, other available papers were examined. Results: Out 35 evaluated studies, 32 articles fully represented rest only sum...

1 Summary The goal of blind deconvolution and source separation is to unravel the effects of an unknown linear transformation on a unknown signal source. For blind deconvolution, the transformation is a linear finite-impulse response (FIR) filter, and for blind source separation it is a matrix of mixing coefficients. A general architecture for these blind adaptive algorithms consists of an adju...

Proxy blind signature is a combination 0f both the properties of proxy signature and blind signature scheme. This scheme is useful in many applications like e-voting, e-payment and mobile agent environments. This paper presents a new proxy blind signature scheme based on discrete logarithm problem(DLP), which satisfies the secure properties of both the blind signature scheme and the proxy signa...

In this paper we propose a passenger bus navigation system using Wireless Sensor Network (WSNs). This System comprises of three Units: Bus Station Unit, Bus Unit and Blind Unit. The Blind people on the Bus Station are provided with a Blind Unit. The blind speaks his destination on the microphone provided on the Bus Station Unit. When the desired bus stops at the station for the Blind, then via ...

A review of the blind analysis technique, as used in particle physics measurements, is presented. The history of blind analyses in physics is briefly discussed. Next the dangers of experimenter’s bias and the advantages of a blind analysis are described. Three distinct kinds of blind analysis in particle physics are presented in detail. Finally, the BABAR collaboration’s experience with the bli...

Solar-Blind Ultraviolet Photodetectors In article number 2111673, Xiaosheng Fang, Zhongming Wei, Hua Xu, and co-workers fabricate a polarization sensitive solar-blind ultraviolet photodetector based on ultrathin KNb3O8 nanobelts synthesized via chemical vapor deposition growth. The device exhibits superior photodetection performance in the region (230–280 nm) with high responsivity (30 A W−1) l...

Abstract This History of Education Society Presidential Address comes at the society's sixtieth anniversary and provides a new conceptual framework that foregrounds recognizing “racist-blind,” not color-blind, ideology in intentional unequal design our educational past present. It highlights systemic racism brought on by dual pandemic moments COVID-19 global racial unrest, with call to action f...
