Waste generated due to various industrial activities are dumped as landfill posing serious environmental complications. Pollution control waste has become one of concern across the globe. This study discusses foundry sand and coconut shell, two byproducts manufacturing agriculture sectors. The most efficient use these components is include them into concrete itself, either a partial substitute ...

This paper presents detailed numerical simulations predicting the effective thermal conductivity of spherical monodisperse and polydisperse core–shell particles ordered or randomly distributed in a continuous matrix. First, the effective thermal conductivity of this three-component composite material was found to be independent of the capsule spatial distribution and size distribution. In fact,...

Waters’ variant of the Boneh-Boyen IBE scheme is attractive because of its efficency, applications, and security attributes, but suffers from a relatively complex proof with poor concrete security. This is due in part to the proof’s “artificial abort” step, which has then been inherited by numerous derivative works. It has often been asked whether this step is necessary. We show that it is not,...

In this note, we describe an error in the proof for CLRW2 given by Landecker et al. in their paper at CRYPTO 2012 on the beyond-birthday-bound security for tweakable block ciphers. We are able to resolve the issue, give a new bound for the security of CLRW2, and identify a potential limitation of this proof technique when looking to extend the scheme to provide asymptotic security.

To develop a sustainable concrete solution, the aggregates and cement in mixture were partially replaced with Cocos nucifera endocarp (coconut shell) aggregate biomass ash (sugarcane bagasse ash) respectively. The fresh hardened properties studied for three types of mixes (i) mix 10-30% replacement (BA), (ii) Bagasse scrap steel fiber 10 - 50% coconut shell aggregate. property is positively inf...
