Regional impacts of periodical cicadas on oak radial increment
Canadian Journal of Forest Research, 2003We investigated the effects of periodical cicadas (Magicicada spp.) on growth of their hosts using records of radial tree-ring growth on oaks (Quercus spp., a common host genus) and pines (Pinus spp., a common nonhost genus) growing within the ranges of 13- and 17-year broods.

Radial increment WSN routing algorithm in deep mine
2017 7th IEEE International Conference on Electronics Information and Emergency Communication (ICEIEC), 2017A radial increment WSN routing algorithm(RIRA) is proposed to reduce energy consumption and improve transmission efficiency caused by complex environment and narrow tunnel of deep mine, in which the wired network layout is limited. Multi-hop routing methods between clusters can reduce energy consumption.

Incremental approach for radial basis functions mesh deformation with greedy algorithm
Journal of Computational Physics, 2017Mesh Deformation is an important element of any fluidstructure interaction simulation. In this article, a new methodology is presented for the deformation of volume meshes using incremental radial basis function (RBF) based interpolation. A greedy algorithm is used to select a small subset of the surface nodes iteratively.

Radial Basis Function Neural Network With Incremental Learning for Face Recognition
IEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics), 2011Conventional face recognition suffers from problems such as extending the classifier for newly added people and learning updated information about the existing people. The way to address these problems is to retrain the system which will require expensive computational complexity.

Radial Increment Response of Appalachian Hardwood Species to a Spring Freeze
Journal of Forestry, 1968Abstract A spring freeze occurred after budbreak and the new foliage of several hardwood species, including American beech, yellow-poplar, cucumbertree, white ash, and northern red oak, was killed or severely injured. Radial increment was affected in some of these species but not in others.

DESIGN OF THE DIE PROFILE FOR THE INCREMENTAL RADIAL FORGING PROCESS
2015In this paper, based on the slab method of analysis, a novel and general approach isdeveloped for studying the radial forging process with curved profile dies. The presented approachis not only more general with respect to previous studies, but it is also easier to understand and useand can be efficiently used for optimization of the die profile ...

Global Optimization Method Based on Incremental Radial Basis Functions
Applied Mechanics and Materials, 2011Global optimization techniques have been used extensively due to their capability in handling complex engineering problems. Metamodel becomes effective method to enhance global optimization. In this paper, we propose a new global optimization method base on incremental metamodel.

Investigation of Radial Basis Collocation Method for Incremental-Iterative Analysis
International Journal of Applied Mechanics, 2016We propose an incremental-iterative algorithm by using the strong form collocation method for solving geometric nonlinear problems. As nonlinear analyses concerning large deformation have been relied on the weak form-based methods such as the finite element methods and the reproducing kernel particle methods, the recently developed strong form ...

Effect of incremental increase in radial neck height on coronoid and capitellar contact pressures
Shoulder & Elbow, 2019Background Over-lengthening of the radial neck has been shown to affect ulnohumeral kinematics and has been proposed to affect radiocapitellar pressures. We hypothesized that an incremental increase in radial neck height increases the capitellar contact pressure and reduces the coronoid contact pressure ...
