摘要:
A method and system for modeling of object-oriented database structures, translation to relational database structures, and dynamic searches thereon. The user may create, edit and manipulate a user's object database (dynamically translated into a set of relational database structures), to create, edit and manipulate objects for that object database (dynamically translated into data for those relational database structures), and to create, edit and manipulate queries to be applied to that object database (dynamically translated into queries to be applied to those relational database structures). A meta-model of the user's object database, which is itself an object database, and which has itself been translated into a set of relational database structures for manipulation by a relational database engine. The meta-model comprises a set of classes, objects, and relationships between classes which model the classes and relationships between classes of the system. Each of these classes may comprise a set of searchable properties, and each of these relationships may comprise an inheritance relationship (between a base class and a derived class) or a data-model relationship (such as a one-to-one, one-to-many, or many-to-many relationship). The data model of the user's object database is modeled by actual objects in the meta-model, and editing or manipulating the user's object database is modeled by creating, modifying, or deleting objects in the meta-model. The meta-model also models itself, in the same manner as it models the user's object database, and may be manipulated in the same manner as the user's object database.

A mirror package is provided which can reflect a laser to an external screen according to a video signal when the laser enters from outside, and a method of manufacturing the mirror package. The mirror is packaged with a glass to protect from external contamination, an inlet and an outlet are formed by, for example, an anisotropic etching on the glass and blocks a reflected light reflected from the glass. The mirror package is formed as a set, combined on a wafer using a wafer level package and diced to individual chips. Subsequently, a productivity is improved and a ghost image or phenomenon is removed.

A method and apparatus for generating discriminant functions for distinguishing obscene videos by using visual features of video data, and a method and apparatus for determining whether videos are obscene by using the generated discriminant functions, are provided. The method of generating discriminant functions includes: creating a first frame set by extracting a predetermined number of frames for each video data unit from a group of video data classified as obscene or non-obscene, and creating a second frame set by selecting the frames; generating a frame based discriminant function by extracting visual features of frames of the second frame set, and then generating a first discriminant value by determining whether each frame of the first frame set contains obscene video data; generating a group frame based discriminant function by extracting visual features of a group of frames of the first frame set, and then generating a second discriminant value by determining whether the frames of the group contain obscene video data; and generating a synthetic discriminant function by using the first and second discriminant values as a representative value of the video data. Accordingly, obscene video data stored in a computer system can be automatically and accurately distinguished.

A method for performing transposition of second-generation superconducting wires, and a superconducting coil manufactured using the same are disclosed. The method for manufacturing a second-generation superconducting wire comprises: slitting a multiple-layered thin superconducting wire film, obtained by epitaxial growth, to form a zigzag-shaped slit portion which includes a plurality of sections each having a predetermined first length and a bent portion having a predetermined second length; continuously and repeatedly processing each section of the slit portion of the superconducting wire film until a desired length is processed to obtain first and second wires using two superconducting wire films; positioning the first and second wires so their bent portions face each other; and interweaving the first and second wires together so the first wire passes over the second wire at their first overlapped portion and below the second wire at their second overlapped portion, to couple the first and second wires.

An image preprocessing function for improving a hot code recognition rate. To implement this function, when a hot code pattern is input, by making a dark portion darker and a bright portion brighter so that an edge portion between black and white is more clearly identified, a difference between the hot code pattern and its background is clarified. Accordingly, an improved hot code recognition rate can be obtained.
