This note calculates the requirements of the anti-aliasing filter for the read-out of the fluorescence detector of the AUGER experiment. The filter order and its cut-off frequency are related to the errors in area and timing reconstruction. 1 System transfert functions The Fluorescence Detector read-out channel consist of a current preamplifier followed by a low pass anti-aliasing filter and a ...

In this paper, class DE inverter with second order constant K band-pass filter is proposed. In the proposed inverter, the band-pass filter is used instead of the resonant filter in class DE inverter presented at the previous papers. By using band-pass filter, two important results can be gotten. One is the sensitivity of the output voltage to the operating frequency is suppressed by using band-...

We calculate theoretical isochrones in a consistent way for five filter pairs near the J and K band atmospheric windows (J–K, J–K , J–Ks, F110W–F205W, and F110W– F222M) using the Padova stellar evolutionary models of Girardi et al. We present magnitude transformations between various K-band filters as a function of color. Isochrones with extinction of up to 6 mag in the K band are also presente...

Proliferation and migration of vascular smooth muscle cells (VSMCs) are important events in the development of diabetic atherosclerosis. Previous studies have suggested that K(Ca)3.1 channels participate in atherosclerosis and coronary artery restenosis. In the present study, we attempted to clarify the roles of K(Ca)3.1 channels in the proliferation and migration of VSMCs using experimental ty...

We calculate theoretical isochrones, in a consistent way, for five filters in the atmospheric window between 1.9μm and 2.5μm, K, K , Ks, F205W, and F222M, using the Padova stellar evolutionary models by Girardi et al. Even when displayed in the same Vega magnitude system, the near-infrared colors of the same isochrone can differ by up to 0.18 mag at its bright end, depending on the filter. We p...

This paper describes the impact of changes in harmonic distortion on value transformer K-Factor. The has a capacity 1.5 MVA and K-Factor 1 under normal conditions. Techniques were installed to reduce distortion, shunt passive filter, detuned reactor. Several condition scenarios created compare distortion's K-factors value. Scenario 1, works K-factor becomes 3.947101, new that can serve load 1.2...
