Examples of cloud in the following topics:

  • Types of outliers in linear regression

    • Outliers in regression are observations that fall far from the "cloud" of points.
    • (3) There is one point far away from the cloud, and this outlier appears to pull the least squares line up on the right; examine how the line around the primary cloud doesn't appear to fit very well.
    • (4) There is a primary cloud and then a small secondary cloud of four outliers.
    • There might be an interesting explanation for the dual clouds, which is something that could be investigated.
    • You will probably find that there is some trend in the main clouds of (3) and (4).
  • Introduction

  • Quantum-Mechanical View of Atoms

    • Atom is a basic unit of matter that consists of a nucleus surrounded by negatively charged electron cloud, commonly called atomic orbitals.
    • Atoms in solid states (or, to be precise, their electron clouds) can be observed individually using special instruments such as the scanning tunneling microscope.
    • This is an illustration of the helium atom, depicting the nucleus (pink) and the electron cloud distribution (black).
    • The nucleus (upper right) in helium-4 is in reality spherically symmetric and closely resembles the electron cloud, although for more complicated nuclei this is not always the case.
  • Spherical Distribution of Charge

    • The charge distribution around a molecule is spherical in nature, and creates a sort of electrostatic "cloud" around the molecule.
    • This distribution around a charged molecule is spherical in nature, and creates a sort of electrostatic "cloud" around the molecule.
    • This image shows the outer electron cloud of a neutral water molecule.
    • Schematic representation of the outer electron cloud of a neutral water molecule.

    • X-ray photons are produced in a cloud of radius R at the uniform rate¦ (photons per unit volume per unit times). the cloud is a distance d away.
    • Assume that the cloud is optically thin.
    • If the cloud is fully unresolved, what is the average intensity when the source is in the detector?
    • If the source is resolved, we can discern different parts of the cloud, so the observed intensity is the integral of the emission coefficient through the cloud,
    • where $b/R$ is the relative distance between our line of sight and the centre of the cloud.
  • Hydrogen Bonding

    • The electronegative atom attracts the electron cloud from around the hydrogen nucleus and, by decentralizing the cloud, leaves the hydrogen atom with a positive partial charge.
    • As in a molecule where a hydrogen is attached to nitrogen, oxygen, or fluorine, the electronegative atom attracts the electron cloud from around the hydrogen nucleus and, by decentralizing the cloud, leaves the hydrogen atom with a positive partial charge.
  • Problems

    • X-ray photons are produced in a cloud of radius $R$ at the uniform rate $\Gamma$ (photons per unit volume per unit time) as seen in the figure.
    • The cloud is a distance $d$ away.
    • Assume that the cloud is optically thin.
    • If the cloud is fully resolved by the detector what is the observed intensity of the radiation as a function of position?
    • If the cloud is fully unresolved, what is the average intensity when the source is in the detector?
  • Problems

    • An optically thin cloud surrounding a luminous object is estimate to be 1 pc in radius and to consist of ionized plasma.Assume that electron scattering is the only important extinction mechanism and that the luminous object emits unpolarized radiation.
    • If the cloud is unresolved (angular size smaller than the angular resolution of the detector), what is the net polarization observed?
    • If the cloud is resolved, what is the polarization direction of the observed radiation as a function of position on the sky?
    • If the central object is clear seen, what is an upper bound for the electron density of the cloud, assuming that the cloud is homogeneous?
  • The Eruption of Mount Vesuvius

    • When Vesuvius erupted on August 25, a cloud of ash spewed south, burying the cities of Pompeii, Nuceria, and the sumptuous villas at Stabiae.
  • Electric Charge in the Atom

    • Typically in modeling atoms, protons and neutrons are regarded as stationary, while electrons move about in the space outside the nucleus like a cloud.
    • The negatively charged electronic cloud indicates the regions of the space where electrons are likely to be found.
    • The electrons cloud patterns are extremely complex and is of no importance to the discussion of electric charge in the atom.
