In this work, the feasibility of partially and totally replacing natural sand with used foundry in self-compacting concrete was studied. Natural replaced 50% 100% vol. by sand. The fresh state properties parameters analyzed study were slump flow, t500, V-funnel, Japanese ring L-box following EFNARC guidelines. Results indicated an improvement when utilized for partial total replacement. mechani...

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.

This paper proposes a test generation method using a compacted test table and a test generation method using a compacted test plan table for RTL data path circuits with DFT where hierarchical test generations are applicable. Moreover, a heuristic algorithm for a compacted test plan table generation is proposed. The proposed methods could shorten test lengths for some RTL data path circuits comp...

Roller compacted concrete (RCC) dam projects are generally initiated in dynamic environment, where space conflicts occur frequently. Construction workers often exposed to dangers posed by activities performed teams other than their own. Therefore, it’s critical for construction security conduct fairly precise exposure assessment. Several research studies have been proposed address this site saf...
