In this article has been studied the dependence of tree planting density, variety-rootstock combinations and water- resource-saving technologies in providing population our country with fresh fruits obtaining a constant plentiful high-quality harvest. Fruit growing is one most important unique areas agriculture. The growth, development productivity young orchards from seed depend on density see...

The tree species density and basal area form structural functional variables of healthy forest ecosystems. Tree are among useful parameters for management natural resources. A study was carried out in Image Forest Reserve (IFR) 2019 to determine area. total 170 plots measuring 20 m x 40 were set along the land cover types at an interval 250 from each other. Trees with a diameter breast height (...

This note further explores the Dirichlet-tree distribution developed by Dennis (1991). An inclusion relationship is given for different tree structures and an independence relationship is given for probabilities in the tree. The posterior, evidence, and predictive density are derived for multinomial observations.

We consider a discrete-time quantum walk Wt given by the Grover transformation on the Cayley tree. We reduce Wt to a quantum walk Xt on a half line with a wall at the origin. This paper presents two types of limit theorems for Xt. The first one is Xt as t → ∞, which corresponds to a localization in the case of an initial qubit state. The second one is Xt/t as t → ∞, whose limit density is given...
