The widely-studied radio network model [Chlamtac and Kutten, 1985] is a graph-based description that captures the inherent impact of collisions in wireless communication. In this model, the strong assumption is made that node v receives a message from a neighbor if and only if exactly one of its neighbors broadcasts. We relax this assumption by introducing a new noisy radio network model in whi...

purpose : to investigate the application of mitomycin-c 0.02% (mmc) in the photorefractive keratectomy (prk) procedure in correcting regressed myopia methods : eighteen eyes of 11 patients with a spherical equivalent (se) of less than -5 diopters (d) who had undergone laser in situ keratomileusis (lasik) more than 2 years before were operated on. at the end of the prk procedure, mmc was applied...

Researchers have proposed many algorithms for localizing faults in networked systems, but it is unclear which algorithm is best suited for a given network; the performance of these algorithms differs markedly for different networks. We develop a framework that can explain these differences by anatomizing the algorithms into their basic choices and analyzing these choices with respect to six def...

In this paper, we introduce a novel algorithm for object tracking in video sequence. In order to represent the object to be tracked, we propose a spatial color histogram model which encodes both the color distribution and spatial information. The object tracking from frame to frame is accomplished via center voting and back projection method. The center voting method has every pixel in the new ...

To assess whether recent seismicity is induced by human activity or is of natural origin, we analyze fault displacements on high-resolution seismic reflection profiles for two regions in the central United States (CUS): the Fort Worth Basin (FWB) of Texas and the northern Mississippi embayment (NME). Since 2009, earthquake activity in the CUS has increased markedly, and numerous publications su...

We investigate the problem of reliable computation in the presence of faults that may arbitrarily corrupt memory locations. In this framework, we consider the problems of sorting and searching in optimal time while tolerating the largest possible number of memory faults. In particular, we design an O(n log n) time sorting algorithm that can optimally tolerate up to O( √ n log n ) memory faults....

the discovery of rna interference (rnai) in recent years has revolutionized biological and medical research. rnai is the sequence-specific gene silencing triggered by double-stranded rna (dsrna). until a couple of years ago only biologists working with caenorhabditis elegans and plants could use rnai technology to gain insight into gene function……

This paper discusses the problem of fault diagnosis under multiple sequential faults occurrence. In industrial applications this type of fault is the most common since the continuous operation of systems/processes is required. The fault diagnosis algorithms should cope with such type of multiple faults, but degradation in their fault isolation capabilities is introduced until the point that the...
