Computer based diagnosis of approach enables to detect abnormalities of red blood cells.
Automated computer-based diagnosis is believed to be fast and accurate if the system is
properly developed and verified. The ...
Postoperative complication may be defined as negative outcome as perceived either by the surgeon or by the patients. It confers an increased risk of reoperation, prolonged length of stay, decline in disposition and increased ...
The main purpose of this study is to discuss the properties of the solutions of the Dirac equation and calculate the Dirac propagator in the presence of a uniform background magnetic field. In particular the focus of the ...
In this thesis, the covariant form of Dirac equation has been modified for a relativistic muon by incorporating the uniform background electric field through the principle of minimal coupling. The Electromagnetic (EM) field ...
this thesis, the electroweak description of neutrino-induced neutral weak transition between Sigma and Lambda hyperons is present. The norm-squared invariant element has been manipulated into a contraction between leptonic ...
Wheat is one of the most important food sources in the world. Classification of wheat grains is essential for controlling the quality of wheat for flour industry, wheat traders and wheat researchers. The main focus of this ...
In ideal Fermions system, at high temperature limit, quantum effects are small but when the temperature is lowered, quantum effects start becoming important. The main purpose of this study was to formulate thermodynamic ...
