Tree Growth Modelling Constrained by Growth Equations

Modelling and simulation of tree growth that is faithful to the living environment and numerically consistent to botanic knowledge are important topics for realistic modelling in computer graphics. The realism factors concerned include the effects of complex environment on tree growth and the reliability of the simulation in botanical research, such as horticulture and agriculture. This paper proposes a new approach, namely, integrated growth modelling, to model virtual trees and simulate their growth by enforcing constraints of environmental resources and tree morphological properties. Morphological properties are integrated into a growth equation with different parameters specified in the simulation, including its sensitivity to light, allocation and usage of received resources and effects on its environment. The growth equation guarantees that the simulation procedure numerically matches the natural growth phenomenon of trees. With this technique, the growth procedures of diverse and realistic trees can also be modelled in different environments, such as resource competition among multiple trees.     

Data Warehousing Stages of Growth

According to the stages of growth theory, things change over time, in sequential, predictable ways. Eight experts participated in a study that identified three data warehousing stages of growth - (1) initiation, (2) growth, and (3) maturity - and the variables that define each stage - data, architecture, stability of the production environment, warehouse staff, users, impact on users' skills and jobs, applications, costs and benefits, and organizational impacts. the data warehousing stages of growth model is useful in understanding and predicting how organizations' data warehouses change. the experts also suggested how recent developments in data warehousing are affecting the stages. Recommendations are given for managing the progression through stages.     

Fast Simulation of Laplacian Growth

Laplacian instability is the physical mechanism driving pattern formation in many disparate natural phenomena. Current algorithms for simulating this instability are slow and memory intensive. A new algorithm, based on the dielectric breakdown model from physics, is more than three orders of magnitude faster than previous methods and decreases memory use by two orders of magnitude. Our algorithm admits a spherical harmonic solution, letting it account for arbitrary boundary data, such as an environment map

发展是自由的增长——评阿马蒂亚·森的《以自由看待发展》

与传统的发展观不同，阿马蒂亚·森将发展看作是“扩展人们享有的真实自由的一个过程”，认为自由不仅是发展的首要目的，还是促进发展的必要手段。森的发展观重构了经济学的伦理基础，以人为本，重视人的“实质自由”的实现。但是，森却忽略了全球化问题，对“不自由”深层原因的探讨也有所欠缺。     

Growth properties of power-free languages

The aim of this paper is to survey the area formed by the intersection of two popular lines of research in formal language theory. The first line, originated by Thue in 1906, concerns repetition-free words and languages. The second line is the study of growth functions for words and languages; it can be traced back to the classical papers by Morse and Hedlund on symbolic dynamics (1938, 1940). Growth functions of repetition-free languages have been investigated since the 1980’s. Most of the results are obtained for power-free languages, but some ideas can be applied for languages avoiding patterns and Abelian-power-free languages as well.In this paper, we present key contributions to the area, its state of the art, and conjectures that suggest answers to some natural unsolved problems. Also, we pay much attention to the tools and techniques that made the progress in the area possible.     

Growth animation of human organs

The growth of the organs of the human embryo changes significantly over a short period of time in the mother's body. The shape of the human organs is organic and has many folds that are difficult to model or animate using conventional techniques. Convolution surface and function representation are a good choice in modelling such organs as human embryo stomach and brain. Two approaches are proposed for animating organ growth: the first uses a simple line segment skeleton demonstrated on a stomach model and the other method uses a tubular skeleton calculated automatically from a 2D object outline. Growth speed varies with the position within the organ and thus the model is divided into multiple geometric primitives that are later glued by a blending operation. Animation of both the embryo stomach and brain is shown. Copyright © 2002 John Wiley & Sons, Ltd.     

The Limits to Growth

Shifting trends in computer industry growth are a source of concern for MIS managers, who must understand the reasons behind the changes and adjust their purchasing plans accordingly. Increasing pressure from corporate management to justify acquisition decisions should force a healthy reexamination of your own assumptions.
