In this paper, we develop a unifying optimization formulation to describe the Dynamic Channel and Power Assignment (DCPA) problem and an evaluation method for comparing DCPA algorithms. DCPA refers to the allocation of transmit power and frequency channels to links in a cognitive network so as to maximize the total number of feasible links while minimizing… (More)
Inspired by the coincidental suicides in 1890 of Elephant Man Joseph Merrick and the Impressionist painter Vincent Van Gogh, Still I Rise fuses two events by presenting a fantasy visualization of Merrick's last dream in an animated Impressionist style. The entire production was animated and rendered on Windows 2000 workstations. The final renders were… (More)
—Multi-channel operation in an ad hoc network can improve robustness and reliability by efficiently managing interference and reducing contention. In this paper, we model four dynamic channel assignment techniques under the same set of assumptions, comparing the efficiency of their power and channel allocations. As the number of channels increases, the… (More)
Painterly animation has till now been a part of research groups and enthusiast. This film attempts to bring it closer to the masses using commercially available software.
INTRODUCTION We report the case of an unusual association of Coffin-Siris syndrome with Mayer-Rokitansky-Küster-Hauser syndrome. This association has never previously been reported in the medical literature. CASE PRESENTATION A nine-year-old Indian girl was referred to our hospital for growth retardation, mental retardation, lax joints, generalized… (More)
