A direct digital frequency synthesizer with multi-channel converters (33; 133) addressing mode accumulator (17; 117) is characterized. 多路转换器接收一系列由数字电路(41-45;141-153)产生的延迟信号. Multiplexer receiving a series by the digital circuit (41-45; 141-153) produces a delay signal. ...
Vacuum Radio Frequency Plasma (VRFP) and Micro Wave Plasma (VMWP) Control of the Plasma obtained from the LASER ablation process SLP500DC Platform 3 in 1 system: The SLP500DC is our third LASER IC decapsulator basic platform. It can also integrate a cross section option for ICs, modules...
In testing single or 3-phase power and energy meters, a standard meter serves as the reference grade standard. It needs exceptionally high accuracy at the power frequency (50 Hz or 60 Hz) for accurate testing. Table 8 lists the typical specifications of 3-phase standard meters. For an ...
Position numbers are at the upper right in each case. Δσ is the standard deviation of the difference between the observed frequency and the expected frequency (Matthews et al., 1994). Note that the maximum scale (upper) is Δσ = 6, and (lower)Δσ = 30.[From Shorts al. (1995)....
However, it can be used to make a straightforward prediction about the effect of writing hand on the relative frequency of reversal of the digits. According to the theory, the implicit right-orienting rule originates, at least in part, from the fact that children learn to write from left ...
The χ2 test was used to evaluate differences in the frequency of nominal variables. Pearson’s correlations were used to investigate continuous relationships between the 2D:4D measures and GIDYQ and UGDS scores in each group. We present the data as means and standard deviations or relative ...

Dutch children from kindergarten (mean age 5−6 years) to the end of primary school (van der Ven, Klaiber, & van der Maas, 2016) showed that while the frequency of inversion errors declined with age, 57 % of children still made inversion errors in Year 6 (mean age 10–11 years)...
