In this study, we investigate and present a new index structure, Triangular Decomposition Tree (TDtree), which can efficiently store and query temporal data in modern database applications. TD-tree is based on spatial representation of interval data and a recursive triangular decomposition of this space. A bounded number of intervals are stored in each leaf of the tree, which hence may be unbal...
Reconstruction of pre-instrumental, late Holocene climate is important for understanding how climate has changed in the past and how climate might change in the future. Statistical prediction of paleoclimate from tree ring widths is challenging because tree ring widths are a one-dimensional summary of annual growth that represents a multi-dimensional set of climatic and biotic influences. We de...
spatio-temporal variability of throughfall (tf) has an important role on the biogeochemical processes,soil, watershed hydrology as well as the nutrient cycle in forests. spatial distribution and temporalstability of tf patterns by five individual persian oak trees (quercus brantii var. persica) in thezagros forests of western iran, ilam, was quantified. sixteen tf manual gauges were placed bene...
