Geometrical Aspects of Wood Aging Based on 3gmap L-system Growth Model

چکیده
In this paper, we propose a new approach to wood aging problems in computer graphics. During its life, wood suffers from various damages due, for example, to insects, fungus or drying. These damages can have an impact on the appearance of wood, for example insects can create galleries in its structure and drying can lead to topological changes or misshapenness. According to botanic literature, it seems obvious that these geometric alterations are dependent on the internal structure of wood. In order to take into account this consideration, we propose to base our approach on a growth model of wood. In this paper we have chosen to tackle the aspects of aging that seem to be the most important and whose impact on the geometry of wood is significant. So, in this paper, we have chosen to focus on: insects and mushrooms attacks, some various kinds of slits and on the phenomenon of erosion.

Comparison of Different Hydraulic Fracture Growth Models Based on a Carbonate Reservoir in Iran
There has been little interest in the application of hydraulic fracture treatment in Iranian oil fields, thanks to the primarily suitable production rates of the vast oil fields. In this paper, hydraulic fracturing treatment was simulated by different models for a carbonate reservoir in the southwest of Iran. Suitable pay zones were nominated based on the lithology, water-oil saturation, geomec...
متن کاملEffect of Pine Wood Vinegar on Germination, Growth and Physiological Characteristics, and Uptake of Elements in Basil
The use of organic materials is increasing in agriculture and industrial products due to their less side effects than chemical materials. In order to study the effect of pine wood vinegar (Pyroligneous acid) on growth and physiological traits of basil, two experiments were designed and conducted in 2014, based on a completely randomized design with 6 treatments (0, 1250, 2000, 2500, 3333 and 50...
متن کاملThe Effects of Population Aging on Economic Growth of Iran through the fertility rate and life expectancy (Overlapping Generation Model Approach)
Abstract Introduction: population aging refers to an age imbalance of the population so that the ratio of young population decreases while aged population grows. Decrease in fertility rate and growing life expectancy are the two key factors in emergence of population aging. The macro economy effects of population aging on economic growth was examined based on the effects of two factors includ...

متن کاملThe effect of simulated dust storm on wood development and leaf stomata in Quercus brantii L
Dust storms are increasingly threatening the forest ecosystem in Western Iran. Due to its coverage of vast area of Zagros forest, the Quercus brantii is at the front line of the attack. Most tree deaths in this forest are from this species. This study aims to investigate the effect of simulated dust on wood development and leaf stomata from seedlings of Persian oak. The oak seedlings were...
