in this paper, a bandpass filter with cutoff frequencies 1.7-11.5ghz have been implemented. for construction of this filter, the first two lowpass and highpass filters with cutoff frequencies 1.7 ghz and 11.5ghz respectively have been designed and then they use in series. we design cutoff frequencies independently, consequently, designing cutoff frequencies doesn’t interfere with each other. th...

BACKGROUND AND PURPOSE The incidence of wall enhancement of cerebral aneurysms on vessel wall MR imaging has been described as higher in ruptured intracranial aneurysms than in unruptured intracranial aneurysms, but the difference in the degree of enhancement between ruptured and unruptured aneurysms is unknown. We compared the degree of enhancement between ruptured and unruptured intracranial ...

Gas phase adsorption of binary mixtures on planar walls in dispersive systems was studied by molecular dynamics simulations, extending a previous study the pure components. The interactions between all particles, fluid as well solid, were described Lennard-Jones truncated and shifted potential with cutoff radius 2.5 σ. Two classes studied: (a) symmetric mixtures, which components also their wal...

We present preliminary results for the mass spectrum of the nucleon and its low-lying excited states from quenched lattice QCD using the domain wall fermion method which preserves the chiral symmetry at finite lattice cutoff. Definite mass splitting is observed between the nucleon and its parity partner. This splitting grows with decreasing valence quark mass. We also present preliminary data r...

We compute the entropy of systems of quantum particles satisfying the fractional exclusion statistics in the space-time of 2+1 dimensional black hole by using the brick-wall method. We show that the entropy of each effective quantum field theory with a Planck scale ultraviolet cutoff obeys the area law, irrespective of the angular momentum of the black hole and the statistics interpolating betw...

Renormalization conditions imposed on quark bilinear vertex functions in the conventional RI/MOM scheme use exceptional momentum configurations. With practical values for the lattice cutoff, these vertex functions are contaminated with unwanted low energy physics (pion pole, zero modes, etc), which is a large source of systematic error. These effects can be reduced by using non-exceptional mome...

There are applications of barrier technology where the variability in hydraulic conductivity from point to point in the barrier, in addition to the average hydraulic conductivity of the barrier, is important. Throughout this chapter, the following application will be referred to in order to demonstrate this point: use of a circumferential soil-bentonite cutoff wall to completely enclose a conta...

This paper presents the design of a digitally-controlled speed electrical drive in the presence of arbitrary external immeasurable load disturbances. The extraction of a known class of external disturbances is achieved by using the novel DOB (Disturbance Observer), in which the discrete-time model of external disturbance is included implicitly. It is shown, analytically, by simulation, and expe...
