recently, due to the very good market in ethane as a feedstock for petrochemical complexes, thereare some plans to make a deep ethane recovery from the gases produced in iran southern fields. inthis work, the feasibility of different technologies for deep ethane recovery from a specified feed gasproduced in one of the iran southern fields is reviewed. three different processes are selected ands...

A geometric random graph, G(n, r), is formed as follows: place n nodes uniformly at random onto the surface of the d-dimensional unit torus and connect nodes which are within a distance r of each other. The G(n, r) has been of great interest due to its success as a model for ad-hoc wireless networks. It is well known that the connectivity of G(n, r) exhibits a threshold property: there exists a...

A 350μW MSK direct modulation transmitter and a 400μW OOK super-regenerative receiver (SRR) are implemented in 90nm CMOS technology. The transceiver tunes 24MHz in frequency steps smaller than 2kHz and is designed to meet the specifications of the Medical Implant Communications Service (MICS) standard in the 402–405MHz band. The transmitter meets MICS mask specifications with data rates up to 1...

Abstract During the last two decades Process Mining has seen a rapid global adoption: first in academics and then corporate business. It evolved into foundational technology, allowing users to discover actual process flows with unprecedented transparency, speed, detail. In business environment no purpose of its own, but companies leverage it identify inefficiencies, improve execution ultimately...
