A network switch and a method thereof for network communications include a first data port interface and a second data port interface supporting a data port transmitting and receiving data at a first data rate and a second data rate, respectively. The apparatus for this invention includes a preprocessor, a detector, a segmentor, a classifier, a classifier systems integrator, a system output and a post processor. Oil-based ink compositions include organic liquids, unsaturated fatty materials having terminal polar functional groups, colorants, and metal salts. The method also includes generating, based at least in part on the determined dominant hand of the user, a graphical user interface for display at a presence-sensitive display operatively coupled to the computing device. The bottom part is pivotally attached to the top part so as to pivot relative thereto.
