A compounded unsaturated polyester resin composition having 10-90 wt % of at least one high viscosity, high molecular weight unsaturated polyester, 10-80 wt % of at least one low viscosity, low molecular weight unsaturated polyester, and 9-30 wt % of at least one monomer. In one embodiment, when a user provides an order for a desired quantity of an assembly type from an external organization, the digital processing system automatically raises a sales order, as originating from the external organization, corresponding to each of a set of components required for manufacturing the assembly type. First, the triple-mode mono-block resonator has three resonators in one block. The amount of angular disagreement of the planes of polarization can be accurately estimated from the positions and heights of the peaks. In an exemplary embodiment, when a point-to-point telephone PSTN connection is established, a screen of information automatically appears at one or both ends of the connection via the Internet. The method classifies a packet by receiving a packet; searching for a rule matching the packet in at least one created decision tree ; and classifying the packet according to a found rule.
