Blind signatures are at the core of e-cash systems and have numerous other applications. In this work we construct efficient blind and partially blind signature schemes over bilinear groups in the standard model. Our schemes yield short signatures consisting of only a couple of elements from the shorter source group and have very short communication overhead consisting of 1 group element on the...

A growing number of devices of daily use are equipped with computing capabilities. Today, already more than 98% of all manufactured microprocessors are employed in embedded applications, leaving less than 2% to traditional computers. Many of these embedded devices are enabled to communicate amongst each other and form networks. A side effect of the rising interconnectedness is a possible vulner...

This paper provides the derivation of speckle reducing anisotropic diffusion (SRAD), a diffusion method tailored to ultrasonic and radar imaging applications. SRAD is the edge-sensitive diffusion for speckled images, in the same way that conventional anisotropic diffusion is the edge-sensitive diffusion for images corrupted with additive noise. We first show that the Lee and Frost filters can b...

To meet the increasing global water demand, local solutions, such as reuse of greywater, are becoming greater importance. While greywater reclamation has been implemented, full-scale adaptation limited by occurrence micropollutants in treated effluent. reduce risks posed micropollutants, advanced post-treatment is required. One promising technology implementation hollow fiber nanofiltration, wh...

Background and Aims: Pregnancy is a sensitive period for all synthetic herbal treatment options. This study aims to classify the medicines used during pregnancy determine their usage rates, side effects, risks, according safety conditions. Methods: was conducted using survey questions directed pregnant women receiving in Obstetrics Gynecology Department. Results: 194 people participated study. ...

Synthetic multichromophore systems are of great importance in artificial light harvesting devices, organic optoelectronics, tumor imaging and therapy. Here, we introduce a promising strategy for the construction self-assembled peptide templated dye stacks based on coupling de novo designed pH sensitive with cyanine Cy5 at its N-terminus. Microscopic techniques, particular cryogenic TEM (cryo-TE...

Traditionally, redaction has been the method chosen to mitigate the privacy issues related to the declassification of textual documents containing sensitive data. This process is based on removing sensitive words in the documents prior to their release and has the undesired side effect of severely reducing the utility of the content. Document sanitization is a recent alternative to redaction, w...

nonstandard finite difference schemes for the black-scholes partial differential equation preserving the positivity property are proposed. computationally simple schemes are derived by using a nonlocal approximation in the reaction term of the black-scholes equation. unlike the standard methods, the solutions of new proposed schemes are positive and free of the spurious oscillations.

Based on the analysis of the classical free viewpoint video (FVV) system, an improved framework of FVV system for high interaction is proposed, which focuses on the requirements and capabilities of receiver side, and aims to achieve low cost of bandwidth, decoder and view generation. Under the framework, disparity search should be completed in server side so as to make view generation to be sim...
