A COMPUTER PROGRAM FOR GRAIN-SIZE DATA1

A computer program for calculation of sample size.

Sample size must be determined while planning a study to ensure that valid conclusions can be drawn when the study is over. different formulae for calculating the required size of the sample are used for different study designs and situations. A computer program is described here to ease the complexity of calculation of sample size for studies designed to use students 't' test.

Optimal Grain Size Computation for

In this paper, we present a method for overlapping communications on parallel computers for pipelined algorithms. We rst introduce a general theoretical model which leads to a generic computation scheme for the optimal packet size. Then, we use the OPIUM 3 library, which provides an easy-to-use and eecient way to compute, in the general case, this optimal packet size, on the column LU factoriza...

Program Partitioning for a Control/data Driven Computer Program Partitioning for a Control/data Driven Computer ?

The paper examines the problem of dataaow graph partitioning aiming to improve the eeciency of macro-dataaow computing on a hybrid control/data driven architecture. The partitioning consists of dataaow graph synchronization and scheduling of the synchronous graph. A new scheduling algorithm, called Global Arc Minimization (GAM), is introduced. The performance of the GAM algorithm is evaluated r...

A Visual Basic Program to Generate Sediment Grain-Size Statistics and to Extrapolate Particle Distributions

Measures that describe and summarize sediment grain-size distributions are important to geologists because of the large amount of information contained in textural data sets. Statistical methods are usually employed to simplify the necessary comparisons among samples and quantify the observed differences. The two statistical methods most commonly used by sedimentologists to describe particle di...
