Effects on radial growth rate on basic density and compressive strength in 10-year-old Swietenia macrophylla planted in South Kalimantan, Indonesia
Published 2025-07-01“…The trees were classified into three categories (fast-, medium-, and slow-growth) based on the stem diameter. Radial variations of basic density and compressive strength parallel to the grain under green conditions were also determined for 15 selected trees (five trees in each radial growth category). …”

Vertical and radial variation in wood acoustical and physical properties of Ailanthus altissima
Published 2025-08-01“…Radially, the damping coefficient was lowest near the pith, increased toward the middle, and reached the highest values near the bark. Shrinkage increased significantly from pith to bark but showed minor axial variation, with similar values at the base and middle, and a significant decrease at the top of the stem. …”

Variation patterns of physical property parameters for pipeline transportation of impurity-containing NH3
Published 2025-07-01“…This effect became more evident with increasing molecular weights, concentrations, and temperatures of the impurities. The variation trends of NH3 regarding density, viscosity, and specific heat capacity were found to be less affected by the polar impurity of H2O, despite a corresponding increase in these values with rising H2O concentrations. …”

Kernel Density Based Spatial Clustering of Applications with Noise
Published 2025-05-01“…Building on this foundation, we introduce a flexible framework incorporating various kernel functions, including uniform, conical, Epanechnikov, cosine, exponential, and Gaussian kernels, to estimate the density distribution of data points. The threshold values are selected to identify high-density regions by retaining the top 90% of points, while excluding low-density points as noise, thereby enhancing clustering precision. …”
