Abstract: A BOM (bill-of-material)-based structured software specification generating method is provided and includes the steps of: declaring a system architecture and an execution flow, declaring a plurality of elements, each of the elements being a programmable unit, generating a plurality of non-repetitive part numbers by a part number generator, each of the part numbers being correspondent to each of the elements which forming a plurality of forms, then both the system architecture and the execution flow representing the relationship between each two of the plurality of forms, defining characteristics of the plurality of elements for, and generating a BOM-based structured specification.

Abstract: A specification generating module outputs a structured specification and includes a plurality of predefined element in which each element is a programmable unit. The specification generating module defines a characteristic of each element in which the characteristics is a combination of the elements to generate forms. The specification generating module includes a specification editing interface comprising sections of a project structure, a resource list and a specification editing area. The section of project structure is used to define an execution flow and a relationship of each form. The section of the resource list is to provide all the elements for review and selected for editing. The section of the specification editing area is used to define the characteristics among the elements including a function, a value, an attribute and an input-output interaction relationship of the selected elements.

Abstract: An embodiment of the invention provides a method for recovering noble metal, which includes providing a carbon-supported catalyst containing a noble metal and a carbonaceous material and separating the noble metal and the carbonaceous material by using various oxidizing solutions to dissolve the noble metal stepwise from the carbon-supported catalyst.

Abstract: In one embodiment a gaitor interface may be used to connect a gaitor to many different types of footwear. The gaitor interface provides a removable attachment between the gaitor and the shoe. One part of the gaitor interface comprises a track that can be mounted along the exterior of the shoe. The track includes a pair of elongated arms that define an interior flex track. Another part of the gaitor interface comprises a connector for attaching to the track. The connector has a bead portion that can be slid into the flex track. The interlock between the bead portion and the flex track provides a releasably secure connection between the gaitor and the shoe. In another embodiment, a convertible shoe having a removable shoe collar is provided. The removable collar may be reversible and may have different linings or covering for the inner and outer surfaces.
