  2. Valence and conduction bands - Wikipedia

    en.wikipedia.org/wiki/Valence_and_conduction_bands

    In solid-state physics, the valence band and conduction band are the bands closest to the Fermi level, and thus determine the electrical conductivity of the solid. In nonmetals, the valence band is the highest range of electron energies in which electrons are normally present at absolute zero temperature, while the conduction band is the lowest range of vacant electronic states.

  3. Thermal conduction - Wikipedia

    en.wikipedia.org/wiki/Thermal_conduction

    Thermal conduction is the diffusion of thermal energy (heat) within one material or between materials in contact. The higher temperature object has molecules with more kinetic energy; collisions between molecules distributes this kinetic energy until an object has the same kinetic energy throughout.

  4. Conductivity - Wikipedia

    en.wikipedia.org/wiki/Conductivity

    Conductivity may refer to: . Electrical conductivity, a measure of a material's ability to conduct an electric current . Conductivity (electrolytic), the electrical conductivity of an electrolyte in solution

  5. Copper - Wikipedia

    en.wikipedia.org/wiki/Copper

    Copper is a chemical element with symbol Cu and atomic number 29, known for its high thermal and electrical conductivity.

  6. Activation function - Wikipedia

    en.wikipedia.org/wiki/Activation_function

    Logistic activation function. The activation function of a node in an artificial neural network is a function that calculates the output of the node based on its individual inputs and their weights.

  7. Exponential distribution - Wikipedia

    en.wikipedia.org/wiki/Exponential_distribution

    In probability theory and statistics, the exponential distribution or negative exponential distribution is the probability distribution of the distance between events in a Poisson point process, i.e., a process in which events occur continuously and independently at a constant average rate; the distance parameter could be any meaningful mono-dimensional measure of the process, such as time ...

  8. Cardiac conduction system - Wikipedia

    en.wikipedia.org/wiki/Cardiac_conduction_system

    The cardiac conduction system (CCS, also called the electrical conduction system of the heart) [1] transmits the signals generated by the sinoatrial node – the heart's pacemaker, to cause the heart muscle to contract, and pump blood through the body's circulatory system.

  9. Bird of prey - Wikipedia

    en.wikipedia.org/wiki/Bird_of_prey

    Birds of prey or predatory birds, also known as (although not the same as) raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and smaller birds).
