Disclosed is a portable internet system, and more particularly, to a method of supporting fast ranging upon handover. The method comprises calculating an action time based on a time when a handover confirmation message is received from a serving Radio Access Station (RAS), in a target RAS; and transmitting a fast ranging information message to a mobile station on the basis of the action time.

An apparatus and method for controlling starting of a motor are disclosed. An exciting coil of a motor is excited by using a controller of an electronic refrigerator without having an extra excitation control circuit, to thereby simplify a component construction for controlling exciting of the motor and thus reduce complexity. The present invention includes: a main coil and an auxiliary coil (sub-coil); an exciting coil that generates an excitation current; a refrigerator control unit that outputs a control signal for controlling an application time of the excitation current when started; and a switch unit electrically connected with the exciting coil and supplying power to the exciting coil according to the control signal outputted from the refrigerator control unit.

The present invention provides a cell or stack for evaluating the performance of a fuel cell and a method of evaluating the performance of the fuel cell using the cell or stack, in which a semiconductor thermoelectric device, attached to the side surface of the unit cell or stack of the fuel cell, is provided maintain the cell or stack at a uniform temperature. The temperatures of an anode and a cathode of the fuel cell can be precisely changed or maintained such that the performance of the fuel cell can also be measured in sub-zero temperature conditions without requiring a separate environmental chamber. A rate of temperature decrease, at which the temperature decreases to a certain sub-zero temperature, or a rate of temperature increase can be precisely controlled.

Disclosed is an integrated multi-measurement system for measuring physical properties including thickness, electrical resistance and differential pressure of a gas diffusion layer for a polymer electrolyte fuel cell with respect to compression. The integrated multi-measurement system simultaneously measures changes in the physical properties of the gas diffusion layer depending on pressure upon measurement of the physical properties of the gas diffusion layer of the fuel cell and also measures through-plane permeability in which a gas is passed through a sample in a direction perpendicular to the sample and in-plane permeability in which a gas is passed through a sample in a direction parallel to the sample.

A highly proton conductive polymer electrolyte composite membrane for a fuel cell is provided. The composite membrane includes crosslinked polyvinylsulfonic acid. The composite membrane is produced by impregnating a mixed solution of vinylsulfonic acid as a monomer, a hydroxyl group-containing bisacrylamide as a crosslinking agent and a photoinitiator or thermal initiator into a microporous polymer support, polymerizing the monomer, and simultaneously thermal-crosslinking or photo-crosslinking the polymer to form a chemically crosslinked polymer electrolyte membrane which is also physically crosslinked with the porous support. Further provided is a method for producing the composite membrane in a simple manner at low cost as well as a fuel cell using the composite membrane.

Disclosed is a process for ranking semantic web resources, comprising the steps of; establishing an RDF knowledge base using diverse tools that support the establishment of ontologies; setting, by class, object and subject weights for an object type attribute and a weight for a data type attribute on the schema composed of classes that constitute a domain and of attributes that describe relationships between these classes; extracting from the RDF knowledge base an RDF triple composed of three portions, i.e., a subject, a predicate and an object; creating a weight matrix of class-oriented attributes based on a set weight and the extracted RDF triple; and operating the created weight matrix of class-oriented attributes to calculate a first eigenvector and obtain a vector for ranking scores of resources.
