A modeling technique is provided. The processor can be formed as a USB device controller operatively connected to the first communications port and USB On-The-Go device controller operatively connected to a second communications port for creating a point-to-point connection to the USB slave device. In accordance with one embodiment, a longitudinally adjustable rod is disposed within the inner tube for adjustment of fluid flow therethrough, and a cylindrical insert having at least one flame stabilizer for stabilizing a flame produced by the burner is attached to the outlet end of the outer tube. The paddles space the disks in an axial direction to form gaps therebetween to form an air path between the disks. The reservoir may be in good direct thermal contact with the laser gain assembly or via a closed loop recirculating fluid heat exchanger. The method include determining which of a plurality of personas defined in the mobile technology platform is an active persona, wherein each persona of the plurality of personas is defined as a set of user preferences associated with an operating system of the mobile technology platform; and customizing a service to the user based on the active persona.
