We present a linguistically-motivated algorithm for reconstructing nonlocal dependency in broad-coverage context-free parse trees derived from treebanks. We use an algorithm based on loglinear classiﬁers to augment and reshape context-free trees so as to reintroduce underlying nonlocal dependencies lost in the context-free approximation. We ﬁnd that our algorithm compares favorably with prior work on English using an existing evaluation metric, and also introduce and argue for a new dependency-based evaluation metric. ...
This is due to the fact that in green leaves,
the chlorophylls and carotenoids have a broad absorption band in the 400-500 nm spectral
region and blue light does not penetrate very deeply into the leaf tissue, and as a result the
fluorescence associated to blue light excitation is mainly generated in the green mesophyll
cells close to the leaf`s surface, therefore little absorption occurs.
Physical units can be specific to the kind of resource
recorded (tonnes, cubic meters, hectares, number
of units) or common to a range of resources. In
this case, a unit-equivalent needs to be found. For
example, material flow accounts which are currently
the main basis for resource-efficiency analysis record
'everything' in tonnes. Another solution is to use
carbon or energy unit-equivalents, as in UNFCCC
reporting. The Ecological Footprint Accounts
propose surface area as a general unit-equivalent.
These solutions are obviously incomplete
A secondary basin corresponds with a second order depositioual cycle, is limited by two erosional surfaces which are also the boundaries of a seismic sequence. In other words, a secondary basin is a component of an overall sedimentary basin.
A secondary basin is formed at the same time with a tectonic phase where the tlu·ee most important factors are faulting, subsidence and uplifting. Basin-forming faults are usually normal faults and are called "syn-depositional fault".
With a reduction of their size, nanoparticles reveal unique properties. A size reduction results in a
substantial increase in the specific surface and the surface Gibbs free energy. This physical
parameter of free energy reflects the fact that chemical reactivity increases rapidly as particle size
diminishes. For example, water has a specific surface of 12.57x10-3
/g at a diameter of one
millimetre but the surface expands to 12.57x10+3
/g at a diameter of one nanometre.
We propose the moving parabolic approximation (MPA) model to reconstruct an improved point-based surface implied by an unorganized point cloud, while also estimating the differential properties of the underlying surface. We present examples which show that our reconstructions of the surface, and estimates of normal and curvature information, are accurate for precise point clouds and robust in the presence of noise.
