Digital halftoning is used both in low and high resolution high quality printing technologies. Our method is designed to be mainly used for low resolution ink jet marking machines to produce both gray tone and color images. The main problem with digital halftoning is pink noise caused by the human eye's visual transfer function. To compensate for this the random dot patterns used are optimized ...

This article describes a defect-oriented test (DOT) approach, which enables complete physical defect-based automatic pattern generation (ATPG) for the digital logic area of CMOS-based designs. Total critical (TCA)-based methods are presented needed DOT views to enable DOT-based patterns detecting all cell-internal and as well cell-external defects. The major aim these new is further reduce defe...

Whole chromosomal DNA probes were used to identify clinical isolates of Mycobacterium tuberculosis, Mycobacterium avium complex, and Mycobacterium gordonae. The probe for M. tuberculosis was prepared from Mycobacterium bovis BCG, which has been shown to be closely related to M. tuberculosis. A probe for the M. avium complex was prepared from three strains representing each of the three DNA homo...

Conventional digital halftoning approaches function by modulating either the dot size (amplitude modulation or AM) or the dot density (frequency modulation or FM). Generally, AM halftoning methods have the advantages of low computation and good print stability, while FM halftoning methods typically have higher spatial resolution and resistance to Moiré artifacts. In this paper, we present a new...
