Abstract:
The national level carbon sequestration estimation for urban trees generally relies on diameter at breast height (DBH) increments. However, limited research on urban tree growth has led to uncertain estimates. In this study, we determined the DBH increment of six major urban tree species in South Korea using three analytical methods (mean, linear regression, and generalized additive model) and two data classifications (total and segmented). Additionally, wedeterminded the aboveground woody biomass (AGWB) increment, which was calculated using the estimated DBH increment, and the accuracy of the

Abstract:
Four theoretical growth functions, Mitscherlich, Logistic, Gompertz and Korf functions, were applied to the growth data on dbh and tree height of individual Eastern White Pine (Pinus strobus) trees to model their growth. The current increments, mean increments and relative growth rates of dbh and height as functions of age were given by derivation from the best fit growth functions. The growth processes of dbh and height were divided into three periods by the inflexion points of the corresponding current increment curves.

Abstract:
Open-grown trees in cities can improve environmental conditions by providing sustainable ecosystem services. Reliable data are necessary for assessing the functions of urban trees. The diameter at breast height (DBH), diameter increment, and annual ring measurements are the main parameters in the development of reliable models. To model periodic mean diameter increments calculated for different time periods (5, 10, 15, 20, and 25 years), a total of 43 open-grown stone pines (Pinus pinea L.) of different diameter classes were sampled in several urban parks in Istanbul, Türkiye.

Abstract Individual tree dbh increment and survival equations were developed for predicting annual dbh growth and annual probability of survival of loblolly pine trees in thinned and unthinned plantations on cutover, site-prepared lands. The dbh increment equation predicts dbh increment froma potential dbh growth function multiplied by a modifier function. The survival equations predicts the probability of survival as a function of crown ratio and the tree's competitive position in the stand. When used together, the equations should be useful to foresters interested in predictingfuture dbh and

Abstract:
The development of red pine (Pinusresinosa Ait.) stands originating under different initial spacings was examined using three measures of growth efficiency that are similar in concept to relative growth rate: diameter at breast height (DBH) increment/crown width, DBH increment/crown projection, and DBH increment/foliage biomass. These three measures of efficiency decreased with increasing DBH in the absence of severe competition and increased with increasing DBH under severe competitive stress. This indicates that small trees occupied their aerial growing space better and utilized their foliag

The sampled stands originated from fires and clear-cuttings that occurred between 1894 and 1941. Stem analysis also permitted the calculation of specific volume increment, which corresponds to the annual volume increment divided by the surface of the cambium.

This paper introduces Dynamic Bayesian Optimisation for Multi-Arm Bandits (DBO-MAB), an algorithm that dynamically adapts hyperparameters of multi-arm bandit algorithms using incremental Bayesian optimisation. DBO-MAB addresses the challenge of tuning hyperparameters in uncertain and dynamic environments, particularly for applications like web server optimisation. It uses a dynamic range adjustment approach based on the interquartile mean (IQM) of observed rewards to focus the search space on promising regions.
