Brief study of Gabor filters for feature extraction

Tutorials/exercises - 7 pages - Physics

Gabor filters have attracted researchers since they extract information quanta in forms of time and frequency, two physically measurable quantities, combined in the most elegant way by the Heisenberg's uncertainty relation. For decades time-frequency analysis has played a central role in...

Hydrodynamic modeling of circulating fluidized bed

Tutorials/exercises - 89 pages - Physics

Fluidization is an operation through which fine granular solids are transformed into a fluid like state through contact with a gas or liquid. Under the fluidized state the gravitational pull on granular solid particles is offset by the fluid drag on them, thus the particles remain in a semi...

Mathematical modeling for axial voidage distribution in CFB

Tutorials/exercises - 6 pages - Physics

Kwauk proposed that the characteristic fine particle distribution in fast fluidization could not be accounted for by the one-dimensional analysis on accelerative motion of particulate fluidization, and presented a physical model for a gas-solid fast fluidization system. The average solid...

Computer simulation study of ionic and non ionic hydration

Tutorials/exercises - 6 pages - Physics

Liquids, solution, and liquid crystals present local, but not long-range order. On one hand particles in liquids interacts much strongly than the particles in gas, and this prevents the use of the usual statistical mechanics methods to predict their structure and properties since the needed...
