Aerated lightweight concrete have many advantages when compared with conventional concrete such as advanced strength to weight ratio, lower coefficient of thermal expansion, and good sound insulation as a result of air voids within aerated concrete. This paper is attention to classified of aerated lightweight concrete into foamed concrete and autoclaved concrete. Also, it is exhibits the raw ma...

Abstract—In this study, the effects of waste marbles as aggregate material on workability and hardened concrete characteristics of self compacting lightweight concrete are investigated. For this purpose, self compacting light weight concrete are produced by waste marble aggregates are replaced with fine aggregate at 5%, 7.5%, and 10% ratios. Fresh concrete properties, slump flow, T50 time, V fu...

A smart meter is resource-constrained device, therefore lightweight cryptographic methods are required. Physical unclonable function(PUF) is promising hardware based lightweight security solution, which makes use of the inherent process variation in semiconductor fabrication process to generate unique ID. This paper presents an PUF based smart meter security with frequency synthesizer(Sx) chain...

As low-cost RFIDs with limited resources will dominate most of the RFID market, it is imperative to design lightweight RFID authentication protocols for these low-cost RFIDs. However, most of existing RFID authentication protocols either suffer from some security weaknesses or require costly operations that are not available on low-cost tags. In this paper, we analyze the security vulnerabiliti...
