in order to investigate the effect of root pruning in morphological and physiological characteristics of juniperus excelsa seedlings an experiment was carried out on transplanted one year-old seedlings. treatments included root pruning intensities (1-slight pruning (2-moderate pruning and 3- control (no root pruning)) .experiment design was completely randomized design. each treatment included ...

Improved efficiency of pruning accelerates the search process and leads to a more time efficient speech recognition system. The goal of this work was to develop a new pruning technique which optimizes the well known probability-based pruning (beam width) by utilization of confidence measurement. We use normalized hypotheses scores to guide the beam width of the pruning process dynamically frame...

This paper outlines some problems that may occur with Reduced Error Pruning in Inductive Logic Programming, most notably eeciency. Thereafter a new method, Incremental Reduced Error Pruning, is proposed that attempts to address all of these problems. Experiments show that in many noisy domains this method is much more eecient than alternative algorithms , along with a slight gain in accuracy. H...

The main goal of this paper is to describe a new pruning method for solving decision trees and game trees. The pruning method for decision trees suggests a slight variant of decision trees that we call scenario trees. In scenario trees, we do not need a conditional probability for each edge emanating from a chance node. Instead, we require a joint probability for each path from the root node to...

The objective of this study was to investigate the effect of pruning in different developmental stages on growth, development, seed yield and active substances of medicinal pumpkin (these active substances are uses for remedy the Benign Prostatic Hyperplasia (BPH)). The experiment was performed in a RCB design. Five pruning treatments in different developmental stages (no pruning, after 3-5 nod...

summer pruning and calcium spray could improve kiwifruits quality. in this study, effect of summer pruning in two times, 2 and 15 days after petal fall alone or in combination with %1 calcium chloride spray on fruit quality and mineral elements contents of ‘hayward’ kiwifruit was investigated. calcium sprayed four times 90 days after petal fall with 15 days intervals. the results showed that su...

pruning of the plant canopy and paclobutrazol application to the root zone are agronomic practices that improve harvest yield in mango (mangifera indica l.) orchards. to assess the effect of pruning and paclobutrazol treatment on the vegetative and reproductive development of ‘ataulfo’ mango, three pruning dates (20 april, 20 may, and 20 june) and three concentrations of paclobutrazol (pbz) (7....

In large vocabulary continuous speech recognition, huge search space results in vast computational cost. While most pruning search strategies can reduce the computation, but the recognition rate often decreases. This paper aims to reduce the computation time without any sacrifice of the recognition rate. By means of the adaptive control theory, a novel pruning method is presented. It can automa...
