Today, the use of anycast address is quite limited. One of the reasons is that there is no routing protocol providing a global anycasting service. In this paper we design and implement a new anycast routing protocol called PIA-SM (Protocol Independent Anycast – Sparse Mode). We focus on PIM-SM (Protocol Independent Multicast – Sparse Mode), which is one of multicast routing protocols available ...

Error vector magnitude (EVM) as a performance metric for M-ary quadrature amplitude modulation (QAM) formats in optical coherent systems is presented. It shown that the calibrated BER, which would otherwise be under-estimated without correction factor, can reliably monitor of near target BER 10?3 phase shift keying (QPSK), 16-QAM, and 64-QAM employing carrier recovery with differential decoding...

Earned Value Management (EVM) is a methodology combining scope, schedule, and resource measurements to assess project performance progress. It involves integrating the three critical elements of covering work cost. Various benefits are associated with use EVM in management. This research aims analyze four units building construction projects using method consisting an analysis performance, esti...

Abstract Superoptimization is a compilation technique that searches for the optimal sequence of instructions semantically equivalent to given (loop-free) initial sequence. With advent SMT solvers, it has been successfully applied LLVM code (to reduce number instructions) and Ethereum EVM bytecode its gas consumption). Both applications, when proven practical, have left out memory operations thu...
