Leptomeningeal enhancement in computed tomography of feline brains
(Univ Federal Rural Pernambuco, 2011-12-01)
Contrast enhancement enables the verification of several pathological conditions that lead to vascular changes and/or breakdown of the blood-brain barrier. Examples of diseases that cause these disorders are: neoplastic ...
A comparative study between recent wavelet nonthresholding methods and the well-established spectral subtractive and statistical-model-based algorithms for speech enhancement under real noisy conditions
(Ieee, 2016-01-01)
In this paper, a comparative study between current wavelet nonthresholding methods for speech enhancement and the well-established spectral subtractive and statistical-modelbased algorithms is performed. The development ...
A Computational Tool for Enhancing Ischemic Stroke in Computed Tomography Examinations
(Springer, 2019-01-01)
Stroke is a cardio-vascular disease that currently ranks in the fifth position among all causes of death worldwide. Computed tomography is the first radiologic examination performed in emergency decisions to diagnose stroke. ...
Enhancement of Breast Periphery Region in Digital Mammography
(Spie-int Soc Optical Engineering, 2018-01-01)
Volumetric breast density has been shown to be one of the strongest risk factor for breast cancer diagnosis. This metric can be estimated using digital mammograms. During mammography acquisition, breast is compressed and ...
Enhanced ferromagnetism in CuO nanowires on the top of CuO nanograins.
(Sociedade Brasileira de Pesquisas em Materiais.Campos do Jordão, 2013-09-29)
In the past few years, a considerable effort has been devoted in order to grow magnetoelectric nanostructured materials. Besides fundamental science, they are very attractive in the electronic/spintronic industry as well ...
Plasma-polymerized acetylene nanofilms modified by nitrogen ion implantation
(2013-06-15)
Thin films were prepared by plasma enhanced chemical vapour deposition (PECVD) from a mixture of acetylene and argon, and post deposition-treated by plasma immersion ion implantation (PIII). The effect of PIII on the ...
