3. Electric-field screening - Wikipedia

   en.wikipedia.org/wiki/Electric-field_screening

   In physics, screening is the damping of electric fields caused by the presence of mobile charge carriers. It is an important part of the behavior of charge-carrying fluids, such as ionized gases (classical plasmas ), electrolytes, and charge carriers in electronic conductors ( semiconductors, metals ). In a fluid, with a given permittivity ε ...

4. Thomas–Fermi screening - Wikipedia

   en.wikipedia.org/wiki/Thomas–Fermi_screening

   Thomas–Fermi screening is a theoretical approach to calculate the effects of electric field screening by electrons in a solid. [1] It is a special case of the more general Lindhard theory; in particular, Thomas–Fermi screening is the limit of the Lindhard formula when the wavevector (the reciprocal of the length-scale of interest) is much smaller than the Fermi wavevector, i.e. the long ...

5. High-frequency vibrating screens - Wikipedia

   en.wikipedia.org/wiki/High-frequency_vibrating...

   High-frequency vibrating screens usually operate at an inclined angle, traditionally varying between 0° and 25° and can go up to a maximum of 45°. They should operate with a low stroke and have a frequency ranging from 1500 to 9000 RPM. Frequency in High frequency screen can be fixed or variable. Variable High Frequency screen is more ...

6. Lookup table - Wikipedia

   en.wikipedia.org/wiki/Lookup_table

   Lookup table. In computer science, a lookup table ( LUT) is an array that replaces runtime computation with a simpler array indexing operation, in a process termed as direct addressing. The savings in processing time can be significant, because retrieving a value from memory is often faster than carrying out an "expensive" computation or input ...

9. Aluminium–silicon alloys - Wikipedia

   en.wikipedia.org/wiki/Aluminium–silicon_alloys

   Aluminium–silicon alloys or Silumin is a general name for a group of lightweight, high-strength aluminium alloys based on an aluminum – silicon system (AlSi) that consist predominantly of aluminum - with silicon as the quantitatively most important alloying element. Pure AlSi alloys cannot be hardened, the commonly used alloys AlSiCu (with ...
