Plantations with fast-growing species play a crucial role in reducing global warming and have great carbon capture potential. Therefore, determining optimal management strategies is challenge the of forest plantations to achieve maximum rate. The objective this work determine rotation that maximize plantations. By evaluating an ecological control problem, presents method manages by planning act...

The article describes the causes of occurrence and forms geomechanical processes manifestation in surrounding coal-rock massif mine workings supported by anchor support. Based on long-term field observations, six typical deformations have been established. Design solutions to strengthen support or complete reinforcement damaged sections during local felling developed. They include: installation...

We show how to efficiently project a vector onto the top principal components of a matrix, without explicitly computing these components. Specifically, we introduce an iterative algorithm that provably computes the projection using few calls to any black-box routine for ridge regression. By avoiding explicit principal component analysis (PCA), our algorithm is the first with no runtime dependen...
