total fertility rate relates to the number of children that a woman bears in the fertility period of her life. fertility function is one of the most important health and population indicators. this indicator affects social, health, economic and cultural factors. this study is an ecological or correlative one. factors affecting total fertility rate in iran in the year 2000 are studied in this pa...

in order to evaluate the relationship between morphological characters in rice lines two populations at f3 generation were grown in research field of agricultural sciences and natural resource university, sari, iran, during 2012. statistical analysis on important agronomic traits showed that maximum standard deviation belonged to total grain number followed by filled grains per panicle and grai...

background & aim: german chamomile is one of the most important medicinal plants. so, assessment of genetic diversity and relationship among the traits are very essential in chamomile breeding programs. determination of the best indirect selection criteria for genetic improvement of essence percent and dry flower yield of german chamomile (matricaria chamomilla l.) populations was investiga...

In this paper, we present a study on the parallelization of the shortest path graph kernel from machine learning theory. We first present a fast sequential implementation of the graph kernel which we refer as Fast Computation of Shortest Path Kernel (FCSP). Then we explore two different parallelization schemes on the CPU and four different implementations on the GPU. After analyzing the advanta...

A SImple yet very efficient PATH mining algorithm (ASIPATH) is introduced in this paper to analyze the click stream data. As in the case of the preceding sequence mining algorithm (webSPADE), ASIPATH requires only one full scan of the data and several partial scans. In parallel algorithm design, it is very common to parallelize a serial algorithm, but ASIPATH is designed for multi-CPU and share...

The single source shortest path problem (SSSP) is a fundamental problem with many theoretical and practical applications and with several effective and well-grounded sequential algorithms. The same can be said about the closely related negative cycle problem (NCP) which is to find a negative length cycle in a graph or to prove that there are none. In fact, all known algorithms for NCP combine a...

This paper presents an architectural model that implements the Multipath execution model of Prolog programs. Multipath performs a partial breadth-rst traversal of SLD-trees, allowing a more eecient execution than the standard depth-rst traversal. Its advantages can be exploited either in a sequential or parallel implementation. In a sequential execution, Multipath reduces the number of operatio...

This research aims to find a non-recurring directed path that will enable all investment regions to achieve the target revenues within the shortest period of time. We call this optimization problem the centralized sequential investment problem (CSIP). “Regional characteristics effect (RC effect)” is assumed to be the major factor that affects the expected time to achieve the target revenue for ...
