The modern national and mercantile systems are positional systems, as described below, and use a circle for zero.
Others, following Herschel's own speculations, thought of them simply as gaseous clouds relatively small patches of diffuse matter within the Milky Way Galaxy, which might be in the process of developing into stars and planetary systems, as described in Laplace's nebular hypothesis.
Typical entities in system environment are peers systems, users, and parent systems as described in Definition 4.
Additionally, our solution can easily be extended into cooperative and distributed sensing systems, as described in Section 4.3.
However, some of the ideas developed for oscillators can be extended to excitable systems, as described in [361 363].
In our case, the aforementioned resources might be different data storage systems, as described in the beginning of this section.
Fifth, the obtained time-frequency characteristics of the eight features are used to determine the handwriting system using the FIR systems as described in Section 3.3.
Various G-CSF concentrations with conditioned medium were assayed by using Ready-Set-Go ELISA kit (R&D systems) as described by the manufacturer.
The proposed transport system is coherent with the collaborative freight logistic systems, as described in [6, 7], both for the horizontal and vertical collaboration.
Among other delivery systems, as described in this theme issue of Advanced Drug Delivery Reviews, virosomes seem ideally suited for delivery of antigens into both MHC pathways.
The formal model of abstract systems as described in Definition 3 does not only elicit the generic model of widely various real-world systems, but also represent the most common attributes and properties of arbitrary systems.
