on this project we try to calculated power of hydrogen on dycarbonil compound in different ways ; the first way is shoster way , for sain power of hydrogen notice the different power between central conforms on it and main conform that’s didn’t have hydrogen joint . or in other way different of energy between open and close form. second way, is average way? this is for way that studied conf...

abstract the present study is concerned with the syntactic deviation in hafezs poetry. poems are known to be accompanied with various linguistic deviations. these deviations may be phonological, morphological and/or syntactic. the relatively high frequency of the cases of the syntactic deviation in hafezs poems makes this rhetorical feature as a main characteristic of his poetry. this thesis, ...

background: in myocardial perfusion spect imaging, images are degraded by photon attenuation, the distance-dependent collimator, detector response and photons scatter. filters greatly affect quality of nuclear medicine images materials and methods: a phantom simulating heart left ventricle was built. about 1mci of 99mtc was injected into the phantom. images were taken from this phantom. some fi...

ABSTRAKElectrical Impedance Tomography (EIT) merupakan teknik pencitraan non-invasif yang merekonstruksi distribusi konduktivitas dari suatu objek. Hasil rekonstruksi citra dengan EIT sangat bergantung pada kemampuan sistem instrumentasinya untuk menghasilkan data akurat. Rangkaian filter salah satu bagian terpenting dalam EIT. Pada penelitian ini telah dirancang dan disimulasikan empat jenis r...

There are several methods of designing an antireflection (AR) coating for a dielectric substrate of refractive index n by depositing one or more nonabsorbing films on it. For example, one approach' is to use only two materials in a coating but to vary the thicknesses of the layers to achieve a filter in which the radiant transmittance vs wavenumber simulates a Chebyshev function. Another approa...

<p>In this paper, a designed circuit used for low-frequency filters is implemented and realized the filter based on frequency-dependent negative resistance (FDNR) as an inductor simulator to substitute traditional inductance, which heavy high cost due coil material manufacturing size area. The active operation amplifier or transconductance (OTA) that easy build in integrated with minimum ...
