The design for a routing table circuit for Ethernet-, IP- and ATM-applications is presented. Starting point for the design was an object-oriented general behavior of the routing table. The selected data structure for the routing table is based on a modification of the structure denominated trie, saving one search level and memory space. The architecture for searching and sorting of data, implemented in hardware, is explained. This modified trie stores 64 K addresses and the associated data, achieving a high performance too. The circuit, which can support a flow of 500000 frames/s, is connected to the PCI Bus. For the implementation a FLEX10K100 from Altera Company was used.

In the long evolution of the earth formation often form a complex geological structure, modeling for these complex geological entities (such as thinning-out, bifurcation, reverse, etc.) still require in-depth 3D modeling study. Because of discontinuity, complexity and uncertainty of distribution of 3D geo-objects, some models only are suitable for regular, continuous and relatively simple spatial objects, and some are suitable for discontinue, complex and uncertain geo-objects, but some improvements on these models, such as, updating of model, maintenance of topological and seamless integration between models, are still to be made. OO-Solid model, put forward by writer in 2002, is an object- oriented topological model based on sections. The OO-Solid Model is an object-oriented 3D topologic data model based on component for geology modeling with fully considering the topological relations between geological objects and its geometric primitives, Comparatively, it accords with the actual requirements of three-dimensional geological modeling . The key issue of 3D geology modeling is the 3D data model. Some data models are suitable for discontinue, complex and uncertain geo-objects, but the OO-Solid model is an object-oriented 3D topologic data model based on component for geology modeling with fully considering the topological relations between geological objects and its geometric primitives. OO-Solid model and data structure are designed. At last, 3D complex geological entities modeling based on OO-Solid are studied in this paper. These study is important and one of the core techniques for the 3DGM.

According to the characteristics of teaching materials diversity and intuitive man-machine communication, the object-oriented teaching aid system based on UML language is designed. Firstly, the principle of UML language is introduced, then the functions of this aid system are described, that is, student information management, operational subjects management, courseware management and system management, etc. On this basis, the system design is analyzed and described from the aspects of design process, application course, data structure and data sheet maintenance, focusing on the refining design of the system, pointing out that this system data can realize the management on the information about students, assessment, courseware and users. Finally the application process of the system is described, which can facilitate the teaching task.

CAD is presented in optical design, the use of object-oriented methods, optical lens structure described. Using object-oriented techniques to describe the object lens, and with VC++ language features to build such systems, construct a data structure of the optical system components. This method has a simple structure, portability, reusability of characteristics.

Object Oriented Methods

We recall that an object-oriented model consists of two major aspects: the static and dynamic. The former covers the implementation of the data structure, which includes the object’s attributes and relationships, whereas the latter is concerned with the object’s operations, which is the implementation of object-oriented methods using SQL and PL/SQL. The static and dynamic parts of an object model actually form a nonseparated unit since accesses to the attributes of an object must be done through the available methods. This raises the concept of encapsulation.

Tree Data Structure

In this paper, a method of automatic NC code programming is studied. The data structure used to store graph information is the base of automatic programming system. By utilizing the object-oriented tree data structure proposed in the paper, the disadvantages of the method caused by using simple data structures can be overcome. In processing information, the judgment of topological relationship between two outlines is very important. The Loop Extremum Method is easy, convenient and with no limitations. The system adds plenty of technological parameters, provides multiple machining patterns. In the end, an example is given to test and verify the system`s functions.
