seed bank is a central topic for plant community restoration. we determined the potential and regeneration capacity of soil seed banks of woody plant patches in conservation of the vegetation in an alpine habitat, since vegetation has completely disappeared in some sites by intensive grazing in the habitat. the study was done in mountainous area of alborz in iran. a total of 20 individual shrub...

Geometric modelers typically define surfaces as images of closed polygonal regions under polynomial or rational maps, called patches. The images, also called patches, do not overlap but join along curves in lR . Differential topologists define surfaces as domains of invertible maps, also called patches, from lR to open sets in lR . The patches cover the surface by overlapping in open subsets. T...

The radiosity approach requires the subdivision of complex surfaces into simple components called patches. Since we assume to have constant intensity over a patch, the generation of regular patches is a desirable property of the subdivision algorithm. We show that constrained Delaunay triangulations produce patches that are as close to equilateral triangles as possible and thus are well suited ...

Stochastic patch occupancy models (SPOMs) are a class of discrete time Markov chains used to model the presence/absence of a population in a collection of habitat patches. This class of model is popular with ecologists due to its ability to incorporate important factors of the habitat patch network such as connectivity and distance between patches as well as heterogeneity in patch characteristi...

The study aimed at determining the effect of acid modified porcine mucin powder on the release and permeation of insulin in transdermal patches. Various batches of insulin patches were prepared by solvent casting method using polysorbate 80 as emulsifying agent and acid treated and untreated mucin powders as base. The patches were evaluated for their physical properties, folding endurance, moi...

We consider the problem of interpolating scattered data in R 3 by an almost geometrically smooth GC 2 surface, where almost GC 2 means GC 2 except in a finite number of points (the vertices), where the surface is GC 1. A local method is proposed, based on employing so-called degenerate triangular Bernstein-B6zier patches. We give an analysis of quintic patches for GC I and patches of degree ele...

We present a novel methodology for deriving finegrained patches of Java software. We consider an abstract-syntax tree (AST) representation of Java classes compiled to the Java Virtual Machine (JVM) format, and a difference analysis over the AST representation to derive patches. The AST representation defines an appropriate abstraction level for analyzing differences, yielding compact patches th...

In [7], A. Lee, K. Pedersen, and D. Mumford study the distributions of 3× 3 patches from digital photographs and range scans. G. Carlsson, T. Ishkanov, V. de Silva, and A. Zomorodian in [3] apply computational topological tools to the dataset of optical images studied in [7] and find geometric structures for high density subsets. One high density subset is called the primary circle, and essenti...
