Abstract: The present invention discloses a method for constructing and optimizing a molecular structure model of lignite, comprising: collecting and processing a lignite sample, analyzing a lignite experimental sample, calculating the number of carbon atoms in lignite and the number of carbon atoms in other parameters, obtaining the sizes of aromatic clusters, and determining the composition features and number of aromatic structural units in lignite; calculating the total number of carbon atoms and the number of aliphatic carbon atoms in lignite; obtaining the categories and number of oxygen-containing functional groups in lignite based on the contents of aromatic hydrocarbon, aliphatic hydrocarbon and various oxygen-containing functional groups, and designing the structural forms of nitrogen and sulfur; constructing a molecular structure model of lignite.

Abstract: A modular jack (3) has an insulative housing (6), a printed circuit board (92), a number of cores (931-934) and a magnetic core (935), a number of conductive wires (936-939) respectively wind around the cores and then around the magnetic core together, and a number of grounding wires. The grounding wires has a first grounding wire having one end connected to the conductive wire and another end winding around the magnetic core for grounding, and other grounding wires respectively having one end load connected to the corresponding conductive wire and opposite end load directly connected to the first grounding wire.

Abstract: A system and method for capturing a plurality of business requirements using a Business Process Outsourcing Language (BPOL), an XML representation for expressing business process flow rules, preferences, business rules and event-action mappings as well as service links, to automate the process of generating business processes for use with Web services. BPOL is used to dynamically construct a search script for an advanced Web services discovery engine to find Web services from both UDDI registries and Web services Inspection Language (WSIL) documents and then create a qualified service list. Then a service selection problem is mapped into a solution space {0,1} for use by an optimization algorithm that performs second level service selection of the best set of services based on the requirements.
