Abstract Pulsed Wave Doppler (PW) is a traditional ultrasound technique used for the diagnosis of vascular diseases. The conventional diagnostic method mainly based on hemodynamic parameters obtained from PW spectrum. However, it relies clinical observation and medical experience through lots patient data investigation analysis. collected are varied by different equipment, detection regions ope...

Updating a video screen involves row replacement, i.e. the task of updating an existing screen row to produce the desired row. In many environments, screen operations require transmitting characters to the terminal by a process that is painfully slow compared to computing speeds. Thus, it is worth while to compute a minimal set of row updating commands, as long as the time to do so does not out...

In this paper, a new letter-oriented perfect hashing scheme based on Ziegler’s row displacement method is presented. A unique n -tuple from a given set of static letter-oriented key words can be extracted by a heuristic algorithm. Then the extracted distinct n -tuples are associated with a 0/1 sparse matrix. Using a sparse matrix compression technique, a perfect hashing function on the key word...

Our goal is to find a mixed strategy (probability distribution on possible plays) for Row which maximizes their expected winnings no matter what strategy Col chooses to execute. Let z denote the winnings of Row player using strategy (x1, x2). Then the solution to the following linear program describes the optimal strategy for Row, since based on any strategy Row chooses, Col may choose a pure s...

1. Introduction. The problem of enumerating n by k Latin rectangles was solved formally by MacMahon [4] using his operational methods. For k = 3, more explicit solutions have been given in [1], [2], [3], and [5]. Wile further exact enumeration seems difficult, it is an easy heuristic conjecture that the number of n by k Latin rectangles is asymptotic to (-n!)'cexp (-),CY,). Because of an error,...

This paper deals with the design problem for recovering a response surface by using a nonparametric Bayesian approach. The criterion for selecting the designs is based on the asymptotic average estimation variance, and three priors for the response are specified. We found the optimal design that minimizes the criterion over the lattice designs with s q-level factors and N runs. The approach we ...
