RIMFRA: Rotation-invariant multi-spectral facial recognition approach by using orthogonal polynomials
(Springer New York LLC, 2019)
This paper proposes a novel rotation-invariant multi-spectral facial recognition approach (RIMFRA) by using orthogonal polynomials. In the first step, a rotation, illumination and noise invariant local descriptor (RinLd) ...
The implementation of the high technology methods of cutting on st 50 alloyed steel and the examination of the effects of cutting operation at the surface of material
(2014)
Since competition has risen in the manufacturing methods of present conditions, the chance of competition has lost in the situations which new or high technologies aren't exactly known. The proper selection is important ...
Cross section measurements of e(+)e(-) -> K+ K- K+ K- and phi K+ K- at center-of-mass energies from 2.10 to 3.08 GeV
(AMER PHYSICAL SOC, 2019)
We measure the Born cross sections of the process e(+)e(-) -> K+ K- K+ K- at center-of-mass (c.m.) energies, root s, between 2.100 and 3.080 GeV. The data were collected using the BESIII detector at the BEPCII collider. ...
Deep learning base modified MLP model for precise scattering parameter prediction of capacitive feed antenna
(WILEY, 2019)
The relations between the antennas' geometrical parameters and design specifications usually consist of linear and nonlinear components. Especially with the increase of the requested performance measures, the design procedure ...
Observation of the decay Lambda(+)(c) -> Sigma(-)pi(+)pi(+)pi(0)
(Elsevier Science, 2017)
We report the first observation of the decay Lambda(+)(c) -> Sigma(-)pi(+)pi(+)pi(0), based on data obtained in e(+)e(-) annihilations with an integrated luminosity of 567 pb(-1) at vs = 4.6 GeV. The data were collected ...
Observation of psi(3686) -> e(+)e(-)chi(cJ) and chi(cJ) -> e(+)e(-)J/psi
(Amer Physic Soc., 2017)
Using 4.479 x 10(8) psi(3686) events collected with the BESIII detector, we search for the decays psi(3686) -> e(+)e(-)chi(cJ) and chi(cJ) -> e(+)e(-)J/psi, where J = 0, 1, 2. The decays psi(3686) -> e(+)e(-)chi(cJ) and ...
Dark photon search in the mass range between 1.5 and 3.4 GeV/c
(Elsevier Science, 2017)
Using a data set of 2.93 fb taken at a center-of-mass energy root s = 3.773 GeV with the BESIII detector at the BEPCII collider, we perform a search for an extra U(1) gauge boson, also denoted as a dark photon. We examine ...
The relationship between elevated magnesium levels and coronary artery ectasia
(2016)
BACKGROUND: Coronary artery ectasia (CAE) without specific symptoms is the localised or diffuse swelling of the epicardial coronary arteries. Magnessium (Mg) plays an important role in cardiac excitability, vascular tonus, ...
Comparative Multiple Sclerosis Lesion Segmentation in Magnetic Resonance Images
(IEEE, 2017)
In this study, the unsupervised clustering method namely K-means algorithm is applied for identifying the multiple sclerosis (MS) lesions in magnetic resonance (MR) images automatically. MS lesion detection is essential ...
Synthesis and Characterization of Hydroxyapatite Powders From Eggshell For Functional Biomedical Application
(IEEE, 2017)
Apatitic phosphates are considered within the category of bioceramics. HA and its derives are used of in the fields of medicine, orthopedics and dentistry in order to support a grow up of new bone cells. HA structures have ...
