Ion and droplet mass-to-charge measurements of electrospray from a single emitter tip were taken using an ExB type filter. The propellant used was the ionic liquid 1Ethyl-3-methylimidazolium tetrafluoroborate (EMI-BF4), which has three distinct anion species, BF4 , [EMI + ] [BF4 ]2, [EMI + ]2 [BF4 ]3 during electrospray operation. Theoretical calculations show that the ExB filter would be able ...

Abstract: As the trend of consumer electronics and mobile communications devices is obviously developing toward to miniature and high-speed processing, the problem involving with electromagnetic compatibility (EMC) or radio frequency interference (RFI) is becoming more critical for the system integration of high-speed digital and RF mixed signal platforms. This paper is mainly focusing on the c...

The prominent increase in English medium instruction (EMI) higher education has triggered the need for investigating EMI practice various contexts. Studies focusing on linguistic attitudes of practitioners and learners are beginning to emerge but there few studies exploring language-related issues practice. In response this, this study investigates how conceptualized, approached navigated. Data...

Este ensaio objetiva realizar uma breve discussão sobre as aproximações e os distanciamentos na concepção materialidade entre fundamentos orientações relacionados ao Ensino Médio Integrado (EMI) a proposta de Escola Unitária gramsciana. Discutimos acerca das reformas da educação profissional do ensino médio nas décadas 1990 2000 destacando escola unitária gramsciana como fundamento desta última...

INTRODUCTION To date, most animal studies of myocardial ischemia have used open-chest models with direct surgical coronary artery ligation. We aimed to develop a novel, percutaneous, minimally-invasive, closed-chest model of experimental myocardial infarction (EMI) in the New Zealand White rabbit and compare it with the standard open-chest surgical model in order to minimize local and systemic ...

Frequency modulation (FM) and random switching methods have been used for reducing conducted electromagnetic interference (EMI) in power converters. Limited theoretical studies and comparisons of these schemes, however, are available. In this paper, a detailed analysis and the spectral characteristics of a random carrier-frequency (RCF) technique for suppressing conducted EMI in an offline swit...

Electromagnetic interference (EMI), once the exclusive concern of equipment designers working with high-speed signals, is no longer limited to a narrow class of high-end applications. Continued innovation in semiconductor technology has resulted in the ready availability of cost-effective, high-performance system-on-chip (SoC) devices, microcontrollers (MCUs), processors, digital signal process...

In this paper, the susceptibility to Electromagnetic Interference (EMI) of an analog signal acquisition front-end (AFE) due EMI distortion in opamp-based pre-conditioning amplifiers is addressed. More specifically, possibility correct EMI-induced errors digital domain by post-processing acquired waveforms discussed and experimentally demonstrated for first time with reference AFE based on EMI-s...
