Abstract: Scenario representation manipulation methods, scenario analysis devices, articles of manufacture, and data signals are described according to some aspects. In one aspect, a scenario representation manipulation method includes accessing a graphical representation comprising a plurality of nodes and a plurality of associations of the nodes, wherein the nodes and the associations of the nodes are indicative of a scenario, providing a plurality of defined structural arrangements, wherein the defined structural arrangements comprise a plurality of nodes and associations of the nodes, analyzing the nodes and associations of the nodes of the graphical representation using the defined structural arrangements, and generating another representation of the graphical representation responsive to the analyzing.

Abstract: Scenario analysis methods, scenario analysis devices, articles of manufacture, and data signals are described according to some aspects. In one aspect, a scenario analysis method includes accessing a representation of a first scenario, accessing a plurality of representations of a plurality of second scenarios, analyzing the representation of the first scenario with respect to the representations of the second scenarios, determining a plurality of relationships of the representation of the first scenario with respect to respective ones of the representations of the second scenarios responsive to the analyzing, and ranking the relationships.

Abstract: A wiping material in the shape of a cup and a handle for holding the material during its use. The wiping material may include several layers with the same or different compositions. For hygienic use, it may have a layer of soft, absorbent toilet paper with, perhaps, an innermost layer of a moisture-impermeable material. The handle typically fits inside of and grasps onto the cup-shaped wipe. Conveniently, a compressible sponge on the end of the handle and slightly larger than the inside of the wiping material retains the material for use. The handle may also eject the wipe after such use. A plunger connects to a shaft in the handle which in turn connects to a washer or some other surface near the sponge. Depressing the plunger moves the cone of material off the sponge where it may fall into some receptacle. A spring within the handle biases the plunger and shaft back into its former position. Utilizing the combination involves placing the handle next to the cone of material and connecting the two together.
