We analyze polarization mode dispersion (PMD) emulators comprised of a small number of sections of polarizationmaintaining fibers with polarization scattering at the beginning of each section. Unlike previously studied devices, these emulators allow the emulation of a whole ensemble of fibers. We derive analytical expressions and determine two main criteria that characterize the quality of PMD ...

This document defines the specific requirements for edge-to-edge emulation of circuits carrying Time Division Multiplexed (TDM) digital signals of the Plesiochronous Digital Hierarchy as well as the Synchronous Optical NETwork/Synchronous Digital Hierarchy over packet-switched networks. It is aligned to the common architecture for Pseudo Wire Emulation Edge-to-Edge (PWE3). It makes references t...

In this paper, we take a MIPS-based open-source uniprocessor soft core, Plasma, and extend it to obtain the Beefarm infrastructure for FPGA-based multiprocessor emulation, a popular research topic of the last few years both in the FPGA and the computer architecture communities. We discuss various design tradeoffs and we demonstrate superior scalability through experimental results compared to t...

To increase the throughput of electronic manufacturing companies, design, prototyping, production, installation and maintenance processes of electronic devices are generally complemented by a number of performance and parametric tests, known as Failure Analysis (FA). In this paper, major FA proposals are considered. In particular, two noninvasive solutions are presented in detail: an advanced b...

This paper presents and evaluates a methodology for the emulation of software faults in COTS components using software implemented fault injection (SWIFI) technology. ESFFI (Emulation of Software Faults by Fault Injection) leverages matured fault injection techniques, which have been used so far for the emulation of hardware faults, and adds new features that make possible the insertion of erro...

The NFC wallet is more popular in the world than before. Many people want to have a convenient payment in shopping, so the NFC wallet becomes an excellent choice for them. The NFC wallet uses the Card Emulation mode to achieve the transaction process. However, the Card Emulation mode does not have the specified secure transaction protocol. Our research provides a secure transaction protocol for...

An attempt is made to defend a general approach to the spatial content of perception, an approach according to which perception is imbued with spatial content in virtue of certain kinds of connections between perceiving organism’s sensory input and its behavioral output. The most important aspect of the defense involves clearly distinguishing two kinds of perceptuo-behavioral skills—the formati...

This paper presents a DVB-RCS satellite emulation system built using the NPBox programmable network emulation system. NPBox allows system components to be modeled both at a higher abstraction level using a finite-state-machine like abstraction, and also at a lower level using customized event guards and actions. Comparison experiments show that the emulated performance is similar to that of a c...

This paper addresses the use of Analog Behavioral Models (ABMs) in an efficient strategy for designing analog emulation engines for large scale power system computation. Through discussion of historical development of analog computation in power system analysis and its present resurgence, we present the need for, and application of ABMs for model verification and validation prior to full struct...
