Abstract With the rapid development of power system, requirement network clock synchronization accuracy is becoming higher and higher, in many cases, it needs to reach microsecond level. In order meet increasing demand, based on analysis basic principle PTP protocol, a physical layer system STM32 MCU DP83640 chip proposed. The time error less than 1 by using timeacc-007 precision measuring inst...

The wireless transmission node designed in this report receives the data generated by ECG detection module, temperature measurement and exercise statistics module using STM32 single-chip microcomputer system. sends results after digital signal processing algorithm calculations to mobile terminal, realizing dynamic display of electrocardiogram, body temperature, volume monitoring arrhythmia. We ...

The importance of pure electric vehicles is increasing in the automotive industry, and vehicle controller a critical component that plays vital role monitoring, controlling, ensuring safety, distributing energy throughout entire vehicle, thereby affecting its economy, reliability. This paper presents design development various module functions, circuit hardware design, working principles for ve...

Given the difficulties In obtaining up-to-date infonnation, I frequently resort to the Ideas, research results , and unpublished works of a number of colleagues, though it is not always possible to cite these sources adequately. I would like to acknowledge collecllvely my colleagues at the Centro Brasilel ro de Anc1;lIse e Planejamento (CEBRAP) and Nucleo de Esludos de Polfticas PlJblicasCampln...

We study a new s-process path through an isomer of Re to improve a Re-Os nucleo-cosmochronometer. The nucleus Re is produced by this new path of Re(n,γ)Re(n,γ)Re. We measure a ratio of neutron capture cross-sections for the Re(n,γ)Re and Re(n,γ)Re reactions at thermal neutron energy because the ratio with the experimental uncertainty has not been reported. Using an activation method with reacto...

In European Portuguese (EP), intonation has a grammatical function. In the available research in EP intonation, production imperatives are said to have an F0 risingfalling contour of large amplitude and are described as having an intonation contour similar to wh-questions, although they present rhythmic differences (Viana, 1987). A possible increase in pitch span was also reported. Two percepti...

We present here a cytosolic tether-and-release system to study the import and dynamics of newly synthesised nuclear proteins. Release is gated by rapamycin-induced recruitment and activation of a viral protease, with cleavage of a peptide linker releasing the tethered cargo. We use this system to investigate nucleo-cytoplasmic divisions in the histone H3.1 & H4 deposition pathway, revealing tha...
