Leca lightweight particles are used for structural and semi structural concrete in different countries. In Iran it is usually used as Mass lightweight concrete, blokes and partitions. In this research an experimental work carried out using Leca concrete to assess its physical and mechanical properties and possibility of constructing high strength lightweight concrete to use as structural elemen...

Currently, due to the growing needs in Communications of Multi-Agent Network, DFT and DCT orthogonal transform which is used in communication systems with a fixed size of 2 p (p is a prime) and 2 respectively do not meet the requirements of future service. We propose the cocyclic Jacket matrices, mathematically let ( ) kl A a = be a matrix, if ( ) 1 1 T kl A a − − = , then the matrix A is a Jac...

For rehabilitation of damaged concrete structures, the durability of repair overlay is a very important issue. Self-compacting concretes (SCC) are known as a suitable repair overlay materials. In this study, the durability of different self-compacting lightweight aggregate concretes (LWSCC) and effect of lightweight aggregate type on them is investigated. 3 mix designs of LWSCC containing three...

I argue that conventional wisdom about attitude reports lumps together theorizing about the attitudes themselves with theorizing about the meaning of attitude reports. Instead of conflating these, I propose to treat them as distinct (although obviously related) topics. A central reason for this separation is the distinction between anaphoric constructions that are internally about the same obje...

the sirri jacket offshore platform was designed and installed in persian gulf of iran in 1975 and has been in service since that time. the importance of offshore structure's stability and the failure of this kind of structure during an earthquake in different active zones revealed that earthquake loading has to be considered. in this paper, magnetorheological (mr) fluid dampers have been propos...

Fundamental to any ballistic armour standard is the reference projectile that is to be defeated. Typically, for certification, consistency of bullet geometry is assumed. Therefore, practical variations in bullet jacket dimensions can have far reaching consequences. Traditionally, internal dimensions have been analysed by physically sectioning bullets – an approach which rules out any subsequent...

A full scale SI engine has been imported in to the CFD tool to analyse the temperature distribution of coolant throughout the cooling channels. The segregated approach solver has been adopted to solve the energy equations along with the RANS two layer turbulence model to find out accordance with the available theoretical and published results. The input values are collected from complete vehicl...
