A reliable electronic voting machine (EVM) is proposed and implemented in this study, which integrated with a biometric fingerprint scanner to ensure secure election process. This EVM includes features such as an interactive user interface, hack-free design master lock. The system has the capability of registering data storing it database through proper authentication. Moreover, lowers requirem...

We propose a fast and accurate signal quality monitoring scheme that uses convolutional neural networks for error vector magnitude (EVM) estimation in coherent optical communications. build regression model to extract EVM information from complex constellation diagrams using small number of received symbols. For the additive-white-Gaussian-noise-impaired channel, proposed shows normalized mean ...

This research proposed analyzing projects from a risk uncertainty perspective by using EVM to predict the systemic (Epistemic Risk) and provisioning (Aleatory risk) uncertainties achieve project success. The results of study synthesized empirical findings with theories concepts. To bridge gap, this focuses on minimizing or alleviating epistemic aleatory uncertainties. method included qualitativ...

A fully integrated pulsewidth modulator for Class-S power amplifiers is presented. It consists of a triangular signal generator, a comparator and output buffer. The HBT BiCMOS design of PWM circuit is applied to the LTE frequency range, which converts digitally modulated 955MHz RF carrier with 2.87GHz sampling clock. This PWM shows an EVM 6.6%, a differential output voltage swing 1.35Vp-p with ...

By exploiting multiple non-degenerate four-wave mixing in a silicon-organic hybrid slot waveguide and 16-ary phase-shift keying signals, we propose and simulate three-input (A, B, C) multicasted 40-Gbaud (160-Gbit/s) optical hexadecimal addition/subtraction (A + B - C, A + C - B, B + C - A, A + B + C, A - B - C, B - A - C). The error vector magnitude (EVM) and dynamic range of signal power are ...

Orthogonal Frequency Division Multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. OFDM has developed into a popular scheme for wide-band digital communication. Despite its advantages, it has a major drawback of its high Peak-to-Average Power Ratio (PAPR) value which degrades its efficiency and increases its cost. In this paper, two proposed systems are disc...

For more than five decades, Earned Value Management Systems (EVMS) have been applied by organizations to manage their projects in different industries. However, many still struggle apply (EVM) techniques assess and reliably control project outcomes. This work investigated the state of practice EVMS. paper identifies challenges facing practitioners, critical EVMS subprocesses, key environment fa...
