A large number of variations for the eecient implementation of distributed simulation protocols on shared as well as distributed memory parallel machines have been proposed in the literature. They are roughly divided into two families: conservative protocols (originated by Chandy and Misra) and optimistic protocols (originated by Jeeerson). Their attained simulation performances as reported in ...

Amelia was built by Real World Interface (RWI) using Xavier-a mobile robot platform developed at CMU on a B24 base from RWI-as a prototype. Amelia has substantial engineering improvements over Xavier. Amelia is built on a B21 base. It has a top speed of 32 inches per second, while improved integral dead-reckoning insures extremely accurate drive and position controls. The battery life is six ho...

About 50 years ago, Sidon called a sequence of integers A = {a l < a 2 < • } a B, sequence if the number of representations of n as the sum of r or fewer a's is at most k and for some n is exactly k. In particular he was interested in B21) , or, for short, B 2 sequences. For a B 2 sequence the sums a,+ai are all distinct. In 1933 Sidon asked me to find a B 2 sequence for which an increases as s...

Indian population is well known for its genetic diversity. Among the numerous endogamous communities, which is restricted very much by custom, marriage and occupation, we have collected a total of 229 individuals from 1996 – 1999 comprising of Parsee, Patels and Vatalia Prajapathi (VP) caste groups. We present here the HLA antigen distribution of these endogamous caste groups and compare their ...

The intersection problem for block a..sks for values of k it is to find two B d and based on the V, with IBI n B:;d k; that is, k common blocks. We define to be the of cornDI.ete graph solve the intersection 1 1.1 Let G be a (undirected) which is some subgraph of another graph H. A G-decomposdion of H is a block (V, where V is the vertex set of Hand B decomposition of H into copies of G. In the...

Matrix We take a detour to introduce abstract matrices. We want to acquire a good understanding of such matrices, since they not only represent matroids, but 74 Chapter 3. From Graphs to Matroids also display a lot of structural information about matroids that other ways do not. An abstract matrix B is a {0, 1} matrix with row and column indices plus a function called abstract determinant and d...
