Furthermore, if the derivative of the state x(t) (or the output y(t)) is accessible during the control process, a proportional and derivative state feedback (PDSF) (or proportional and derivative output feedback (PDOF)) controller can be equipped to stabilize the closed-loop descriptor
Burnt/Smoky--This odor and flavor descriptor
is similar to that found in burnt food.
The vanillin and cis-methyl-octalactone could be regarded as direct contributors and/or possible enhancers of this descriptor
In this category, (Steder & Rusu 2010) introduced the NARF descriptor
(Normal Aligned Radial Feature).
Exploitation of the embedding method allows the immediate construction of visual vocabularies of a database without to compare descriptor
vectors of database with them, significantly reducing construction time.
At the initial stage of work for all molecules simplex descriptors
are calculated (about 2 thousands), they are weighted for the mixtures according to the molar concentration of the mixture components.
The platform provides an application that allows the user to specify the URI of the service descriptor
he/she intends to annotate; the platform retrieves the descriptor
by issuing an HTTP request to the supplied URI, starting then the process of semantic annotation.
The image descriptor
is a so called local descriptor
, computed not for the entire image, but only for selected keypoints in the image.
The optimized geometries along with the molecular orbital and vibrational frequency information were be used to calculate over 400 molecular descriptors
containing constitutional, topological, geometrical, charge-related, semi empirical and thermo-dynamical descriptors
using CODESSA software .
2009b) also proposed to compress the SIFT descriptor
with Karhunen-Loeve transform, yielding approximate 2 bits per SIFT dimension.
The third descriptor
(SpMax4_Bh (e)) has a low correlation and high distribution for all molecules (Fig 5).
In this region, the previous procedure is repeated changing only the geometrical descriptor
