The French Academy units of time and length — the second and the meter — are traditionally considered independent from each other. However, it is a matter of fact that a meter simple pendulum beats virtually the second in each semi oscillation, a 'surprising' coincidence that has no physical reason. We shortly review the steps that led to the choice of the meter as the ten millionth part of the...

PURPOSE To evaluate the difference in intraocular lens tilt and decentration measurements with 2 Purkinje meters. SETTING Vienna Institute for Research in Ocular Surgery, Hanusch Hospital, Vienna, Austria. DESIGN Prospective evaluation of diagnostic test. METHODS This single-center study included pseudophakic patients in 2 substudies in which 3 consecutive measurements were performed with...

The Volume- Unit (VU) meter, used in speech research prior to the advent of computers and modern signal processing methods, is described in signal processing terms. There are no known software implementations of this meter, which meet the 1954 ASA standard and provide the instantaneous needle level. Important speech applications will be explored, such as making comparisons of speech levels to e...

An evaluation of a pulsed-eurrent resistance meter ("Shigometer®", Model No. 7950) for facilitating detection of decay was performed on wood blocks of giant sequoia heartwood and of white fir sapwood. As decay progressed over a 12-week incubation period, a trend of lower meter readings was obtained, confirming reported field measurements of other workers. Variability in meter readings in situat...

With the development of the society, the demand of electric power becomes bigger and bigger. The phenomenon of unbalanced electricity in different time is worse and worse. In order to adjust electric power burthen with reason and save energy, we put forward the design of a novel multi-rate three-phase watt-hour meter. The design principle of a newfashioned multi-rate three-phase watt-hour meter...

Feeling the beat and meter is fundamental to the experience of music. However, how these periodicities are represented in the brain remains largely unknown. Here, we test whether this function emerges from the entrainment of neurons resonating to the beat and meter. We recorded the electroencephalogram while participants listened to a musical beat and imagined a binary or a ternary meter on thi...

The new semi-experimental method for simulation of the turbine flow meters rotation in the transitional flow has been developed. The method is based on the experimentally established exponential low of changing of dimensionless relative turbine gas meter rotation frequency and meter inertia time constant. For experimental evaluation of the meter time constant special facility has been developed...

We examined the influence of incidental exposure to varied metrical patterns from different musical cultures on the perception of complex metrical structures from an unfamiliar musical culture. Adults who were familiar with Western music only (i.e., simple meters) and those who also had limited familiarity with non-Western music were tested on their perception of metrical organization in unfami...

This paper presents a method for the extraction of music meter and tempo from raw polyphonic audio recordings, assuming that music meter remains constant throughout the recoding. Although this assumption can be restrictive for certain musical genres, it is acceptable for a large corpus of folklore eastern music styles, including Greek traditional dance music. Our approach is based on the selfsi...

Most chip producers perform delay testing to detect chips that are affected by defects that adversely affect timing. Several delay fault models have been introduced to guide delay test generation. But similar to static (i.e., slow speed) testing, there is always the question of which fault models are best for ensuring quality. MEasuring Test Effectiveness Regionally (METER) is an approach for e...
