Abstract--The expected number of retransmissions is a very important parameter to evaluate the multicast performance. It is often used to estimate other performance parameters such as the bandwidth consumption and delay. A simple and efficient evaluation to these parameters is helpful for design of multicast protocols. In this work, we will derive a good analytical evaluation to the number of r...
BACKGROUND Early detection of disease outbreaks enables public health officials to implement disease control and prevention measures at the earliest possible time. A time periodic geographical disease surveillance system based on a cylindrical space-time scan statistic has been used extensively for disease surveillance along with the SaTScan software. In the purely spatial setting, many differe...
We present a data{parallel formulation of an adaptive version of Anderson's method for N {body particle interactions. Our formulation consists of a storage and computationally eecient array{based representation for the nonuniform hierarchy that models arbitrary particle distributions for the computational procedure. We also present data{parallel implementations (in HPF) of several well known pa...
This paper proposes a risk scoring model to assess the performance of 27 US companies listed online by applying Data Envelopment Analysis (DEA) and comparing with the traditional financial measure Return on Equity (ROE). The DEA evaluation process involves two processes: (1) computation of operating efficiency and effectiveness to measure a company’s operating performance, and (2) measurement o...
A method is presented for segmenting documents into conceptually related areas. Determining the equivalence of text is often based on the number of word repetitions. This approach is unsuitable for detecting short segments because terms tend not to be repeated across just a few sentences. In this paper we investigate the contribution of two other lexical features to find related words: collocat...
