background: periodontitis is common in adults and cardiovascular diseases (cvd) are the most common cause of adult death in the world. this study aimed to investigate the relationship between cvd and periodontitis. methods: sixty patients with myocardial infarction (mi) as case and 63 subjects with periodontitis without mi as control were studied. periodontitis was assessed according to ramfjor...

optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. the distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

This paper presents a new approach for state adequacy evaluation of sampled system state in composite power system reliability analysis. Generalized regression neural network (GRNN) is used in conjunction with non-sequential Monte Carlo simulation (MCS) to evaluate the loss of probability and the power indices. GRNN approach predicts the test functions for all the sampled states after sufficien...

This paper shows that not every scan cell contributes equally to the power consumption during scan based test. The transitions at some scan cells cause more toggles at the internal signal lines of a circuit than the transitions at other scan cells. Hence the transitions at these scan cells have a larger impact on the power consumption during test application. These scan cells are called power s...

A new method for power estimation in sequential circuits is presented that is based on a statistical estimation technique. By applying randomly generated input sequences to the circuit, statistics on the latch outputs are collected, by simulation, that allow e cient power estimation for the whole design. An important advantage of this approach is that the desired accuracy can be speci ed up-fro...

─ In this paper, the design process of a novel Wilkinson power divider is presented. The proposed power divider features a simple structure with open stubs at each port. With slight changes of the dimensions of open stubs, designed power divider can suppress combinations of each two desired order harmonic simultaneously. From the measured results, 45 dB and 43 dB suppression for 3 and 5 harmoni...

Materials with a zero refractive index support electromagnetic modes that exhibit stationary phase profiles. While such materials have been realized across the visible and near-infrared spectral range, radiative dissipative optical losses hindered their development. We reduce in zero-index, on-chip photonic crystals by introducing high-Q resonances via resonance-trapped symmetry-protected state...

We propose an empirically informed measure of the voting power that relaxes the assumptions of equally probable and independent votes. The behavioral power index measures the voter’s ability to swing a decision based on the probability distributions of the others’ behavior. We apply it to the Supreme Court of the United States using roll-call data to estimate voting probability distributions, w...
