Provided are a system and method for interworking Service Capability Features (SCFs) and protocols in an open service gateway. The system includes service capability features that generate and process various protocol messages, and a protocol stack that enables an interwork with a communications network. The protocol stack includes: one or more units that maintain various protocols, a unit that performs data connection and transmits and processes messages, and a unit that manages the various protocols. In the protocol stack, protocol identifiers that differentiate the protocols from one another, and message identifiers that differentiate service capability features from one another are stored in the unit that manages the various protocols.

Disclosed is a copolymer for liquid crystal alignment having a photoreactive group, a mesogen group, a thermosetting group, and a crosslinking group, a liquid crystal aligning layer including the copolymer for liquid crystal alignment, and a liquid crystal display including the liquid crystal aligning layer. Since the liquid crystal aligning layer has excellent thermal stability and no residual image, the liquid crystal aligning layer is usefully applied to the liquid crystal display.

The object of this invention is to provide a steel cord, which has ultrafine steel filaments with a diameter of 0.04-0.14 mm stranded with each other so as to reinforce a tire carcass, and a radial tire for a passenger car using the same. The steel cord includes one core filament with a diameter of 0.04-0.14 mm and 4-7 sheath filaments, each having a diameter of 0.04-0.14 mm, spirally stranded around the core filament. At this time, the steel cord has a diameter of 0.2-0.5 mm and shear strength of 25-35 kgf. Additionally, each of the sheath filaments has a smaller diameter than the core filament, and the core filament and the sheath filaments are made of the steel filaments. The radial tire includes the tire carcass provided with the steel cord and a topping sheet, and the steel cord is embedded in the topping sheet such that a rubber gauge ratio is 200-500 % and a rubber clearance ratio is 60-250 %. The steel cord has improved physical properties, such as shear strength and durability, to reduce a thickness of a carcass including the steel cord, leading to the reduction of a weight of the radial tire. Furthermore, controlling stability and durability of the radial tire are improved, thereby reducing costs of maintenance of the passenger car.

Provided is a flow generation method for Internet traffic measurement. In the flow generation method, dependency between packet collecting time and flow generating time is removed using a virtual timer and a flow generation completion processing interval is controlled to skip by a unit time in response to a user's request. Also, a fragmented packet processing method is selectively used at need and a FIN timeout is applied selectively to a timeout mechanism used in flow generation completion. Thereby, this invention can improve accuracy and efficiency of Internet traffic measurement.
摘要:
Polyamic acids and corresponding polyimides are prepared by reacting polyfunctional amines, aromatic polyfunctional anhydrides or esters thereof, and allyl-nadic anhydride end capping agents, the resulting products exhibiting excellent properties and being suitable for the preparation of prepregs, composites, adhesives, coatings, and the like.
摘要:
Disclosed is a multi-functional monomer including a heat-curable functional group as well as a typical photoreactive group. In the multi-functional monomer, the photoreactive group is not chained to a main chain of a polymer. Thus, since it is possible to perform desirable alignment treatment even though polarized UV is radiated for a short time, the production time and the production cost are reduced and alignment regulating force of liquid crystals is increased, thereby increasing a dichroic ratio.
