The Eastern Igbo are best known for masquerades associated with the Iko okochi harvest festival, in which the forms of the masks are determined by tradition, though the content of the play varies from year to year.
Accordingly the dimensions of masks are determined.
Taking into account that the reflective surfaces should be over the sea and that the observations from the lower elevation angles should be avoided due to the strong multipath effect, the azimuth and elevation mask were determined to be 60° to 300° and 15° to 90°, respectively.
For a given photo-resistive mask, a form of profile and duty cycle (the ratio of width to period) of the elements in the periodic structure, obtained as a result of wet etching of the metal layer through chalcogenide mask, were determined also by rate and time of metal etching.
The oxide layer is treated with 1,4-butanediphosphonic acid to give a monolayer pattern whose composition and spatial conformity to the photolithographic mask are determined spectroscopically.
In other words, the luminance masking,, is determined by the DC term and the location in a subblock.
For that, the threshold of the image intensity to outline the mask was determined from a histogram of image intensities (100 bins).
Since all the radar range gates satisfying the mask are determined at a certain local time, we searched for the range gate, that received the maximum power, and recorded the corresponding slant range and elevation angle values.
The amount of forward masking is determined by the interaction of a number of factors including masker level, the temporal separation of the masker and the signal, frequency of the masker and the signal, and duration of the masker and the signal.
Using Slidebook™, masks of individual mitochondria were generated, and the center of area (centroid) of each mask was determined.
