A Dynamic Separator Algorithm
Our work is based on the pioneering work in sphere separators done by Miller, Teng, Vavasis et al, [8, 12], who gave efficient static (fixed input) algorithms for finding sphere separators of size s(n) = O(n d−1 d ) for a set of points in R. We present dynamic algorithms which maintain separators for a dynamically changing graph. Our algorithms answer queries and process insertions and deletion...
متن کاملA Calculus in the Tonsil
To the Editor, The Indian Medical Gazette Sir,?In the issue of the Indian Medical Gazette of September 1933, Dr. S. C. Sarkar described a case of pea-sized concretion in the tonsil under the heading ' A Calculus in the TonsilHe asserted that he could find no previous record of a stone in the tonsil. I beg to draw your readers' attention to the Indian Medical Gazette of April 1931, page 199, whe...
متن کاملA Weighted Planar Graph Separator
Given a weighted planar graph, we construct a simple separating cycle C whose interior and exterior both weigh at most 2/3 of the total weight. The cycle C uses k jumps across the faces and ordinary edges with cost O(1=k) of the total edge cost. This theorem is the main component of a PTAS for the weighted TSP problem 4].
متن کاملBuilding a Binaural Source Separator
We propose a number of cues and a strategy for combining them that could be used by a binaural machine to perform source separation. Our previous work has used the single cue of interaural phase difference (IPD) to segment the time-frequency plane using an EM algorithm. We see this as a first step towards a larger and more complete system that takes advantage of more of the cues available to a ...
متن کاملTonsil fibromatosis.
Fibromatosis is a non-metastatic, however locally invasive tumor that may infiltrate muscle, fat, and bone. It may be fatal depending on its location. Tumors in the head and neck are particularly dangerous. These fibroblast tumors have poorly defined margins and are not encapsulated. Anaplasia and invasion of nerves and vessels are not present; mitosis is rare and there may be collagen between ...
