partial rootzone drying (prd) is a new irrigation technique which improves water use efficiency without significant yield reduction in grape. to study the effects of partial rootzone drying and green pruning on yield and yield quality of thompson seedless grape a split plot experiment with randomized complete block design and three replications was conducted. the experiment was performed in tak...

In order to investigate the effect of pruning and potassium nutrition on pumpkin grain yield and quality, a factorial experiment based on complete block design with four replications was carried out in nooshar village of ardabil province, Ardabil, Iran, in 2007. Experimental factors include potassium nutrition in three level (0, 75 and 150 kg/ha from potassium sulfate) and stem pruning (without...

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...

One of the key challenges for operations researchers solving real-world problems is designing and implementing high-quality heuristics to guide their search procedures. In the past, machine learning techniques have failed to play a major role in operations research approaches, especially in terms of guiding branching and pruning decisions. We integrate deep neural networks into a heuristic tree...

Various factors a ecting decision tree learning time are explored. The factors which consistently a ect accuracy are those which directly or indirectly (as in the handling of continuous attributes) allow a greater variety of potential trees to be explored. Other factors, e.g., pruning and choice of heuristics, generally have little e ect on accuracy, but signi cantly a ect learning time. We pro...

An on{line learning algorithm for pruning state space search is described in this paper. The algorithm is based on a nite state machine which is both created and used in the search. The pruning technique is necessary when memory resources in searching huge problem spaces are restricted. A duplicate sequence is a generating path in the search tree that has a counterpart with smaller weight. The ...

We describe an exact dynamic programming update for constrained partially observable Markov decision processes (CPOMDPs). State-of-the-art exact solution of unconstrained POMDPs relies on implicit enumeration of the vectors in the piecewise linear value function, and pruning operations to obtain a minimal representation of the updated value function. In dynamic programming for CPOMDPs, each vec...

Fast Fourier transforms (FFT) and Inverse Fast Fourier Transform (IFFT) processing is one of the key procedures in popular orthogonal frequency division multiplexing (OFDM) communication systems. This paper presents the study of an efficiency of the fast Fourier transform may be increased by removing operations of input values which are zero, and of output values which are not required; this pr...
