Repetition Detection in a Dynamic String [PDF]
, 2019 A string UU for a non-empty string U is called a square. Squares have been well-studied both from a combinatorial and an algorithmic perspective. In this paper, we are the first to consider the problem of maintaining a representation of the squares in a ...

Growth pattern analysis of major coniferous tree species in South Korea
Forest Science and Technology, 2018 The size growth patterns of major coniferous trees species Pinus densiflora (Pd), Pinus koraiensis (Pk), and Larix kaempferi (Lk) in South Korea were found and compared using stem analysis.

Systematic and Stochastic Variations in Pulsar Dispersion Measures [PDF]
, 2016 We analyze deterministic and random temporal variations in dispersion measure (DM) from the full three-dimensional velocities of pulsars with respect to the solar system, combined with electron-density variations on a wide range of length scales ...

Machine learning: Modeling increment in diameter of individual trees on Atlantic Forest fragments
, 2020 Growth models at individual levels allow a more detailed description of the forest dynamics. However, many fittings using statistical models have shown low performance in native forests due to variation between the increments of different trees or ...

Nonlinear Volatility of River Flux Fluctuations [PDF]
, 2002 We study the spectral properties of the magnitudes of river flux increments, the volatility. The volatility series exhibits (i) strong seasonal periodicity and (ii) strongly power-law correlations for time scales less than one year. We test the nonlinear

An improved lumped parameter method for building thermal modelling [PDF]
, 2014 In this work an improved method for the simplified modelling of the thermal response of building elements has been developed based on a 5-parameter second-order lumped parameter model.
