Plants fumigated with 40ppbv, 80 ppbv and 120ppbv concentrations of O3 exhibited significant reduction in total chlorophyll content, RuBP carboxylase activity and net photosynthesis. The reduction in total chlorophyll activity ranged from 12 to 36% in Bauhinia variegata, 11 to 35% in Ficus infectoria and 3 to 26% in Pongamia pinnata on fumigation with O3, while the RuBP carboxylase activity was...

the quality of plant stocks in the nursery has proven to be a key determinant factor in precocity of fruit bearing period and the size of tree crops. the quality of these trees is related to growth strength of the applied rootstock, the tendency of the cultivars to produce branches, the growth season's weather conditions as well as the efficiency of different treatments stimulating branchi...

six different Wavelet based Image Compression techniques are analyzed. The techniques involved in the comparison process are Embedded Zero tree Wavelet (ezw) , Set Partitioning In Hierarchical Trees (Spiht), Spatialorientation Tree Wavelet (stw), Wavelet Difference Reduction (wdr), Adaptively Scanned Wavelet Difference Reduction (aswdr) and Spiht_3d. Here, there are six types of Wavelet transfo...

Abstract—Images are prone to noise induction where noise can be introduced by the medium of transfer or during image acquisition. Different filtering procedures are used for noise reduction to improve the visual quality and understandability of images. In this paper we have undertaken four types of noises and applied on a particular image. The filtering of these noises is done using four differ...

It present the comparison of the performance of two different compression wavelet schemes namely Spatial-orientation Trees Wavelet (STW) and Adaptively Scanned Wavelet Difference Reduction (ASWDR). The paper analyses the compression schemes using gray scale image and color scale Image such that the quality of the reconstructed image. The characteristics of quality performance is calculate STW a...

We introduce the notion of a hereditary property for rooted real trees and we also consider reduction of trees by a given hereditary property. Leaf-length erasure, also called trimming, is included as a special case of hereditary reduction. We only consider the metric structure of trees, and our framework is the space T of pointed isometry classes of locally compact rooted real trees equipped w...
