Assignment about MRI Physics

The magnetic moment is considered as a vector quantity whose direction is perpendicular to the current loop in a right-hand-rule direction. The magnetic moment of nuclei are the magnetic moment of the nucleus that arises from a spin of protons and neutrons. A magnetic moment of nuclei is dipole moment – the quadrupole moment causes a shift in the hyperfine structure (Mangrum, 2012). Nuclei with non-zero spin have a non-zero magnetic moment while that have zero spins have zero magnetic moments. Different isotopes of an element have a different nuclei magnetic moment. A nucleus with an even number of protons ...

Gravitational, electromagnetic, strong and weak nuclear forces. Gravitational force is an attraction between any two pieces of matter in the universe. Electromagnetic force is present in pieces of matter, which are able to carry electrical charge. Strong force is holding the nuclei of atoms together. Weak force is responsible for radioactive decay. Molecules are built from the atoms and atoms consist of protons, neutrons and electrons. Protons and neutrons are built of smaller particles called quarks. Electromagnetic spectrum is the range of all the light in the universe. Depending on the wavelength and frequency there are radio, micro, infrared, ...

Abstract

In the recent times, scientists in the discipline of artificial intelligence are confused which approach closely imitates the structure of a human brain. The best two approaches are bottom-up, or the top-down, and they comprise of both their advantages and disadvantages. The top-down approach has the capability to perform high-level tasks since it is programmed (Russell et.al 27). On the contrary, the bottom-up approach is capable of modeling the lower-level human functions such as motor control, image recognition, and learning capabilities. Each method operates perfectly where the other method is imperfect. Therefore, to establish the advantages and disadvantages of ...
