  • The Locator/Identifier Separation Protocol (LISP) is a new routing architecture that implements a new semantic for IP addressing. It enables the separation of IP addresses into two new numbering spaces: Endpoint Identifiers (EIDs) and Routing Locators (RLOCs). This approach will solve the issue of rapid growth of the Internet's DFZ (default-free zone). In this paper, we propose an algorithm called the Propagated-Mode Mapping System to improve the map request process of LISP-DDT.

  • 본 논문은 LISP의 기본적인 특성으로 간주되는 조건 표현과 회기에 대한 철학적 분석이다. 특히 여기서는 논리적 결합사들과 LISP의 원초적 용어들을 비교하고 있다. LISP은 현대 철학자들이 구성했던 이상언어의 사상을 계승한 것으로 여겨진다. 이러한 점에서 인공지능 연구와 철학 간의 학제적 연구가 절실히 필요하다는 논지를 몇가지 검토해 보았다.

  • This paper proposes a network-based mobility control scheme in wireless/mobile networks, which is based on the Locator-Identifier Separation Protocol (LISP). Compared to the existing LISP mobility scheme, the proposed scheme is featured by the following two points: 1) each LISP Tunnel Router (TR) is implemented at the first-hop access router that mobile nodes are attached to, and 2) for handover support, the LISP Routing Locator (RLOC) update operation is performed between Ingress TR and Egress TR. By numerical analysis, it is shown that the proposed scheme can reduce the handover latency much more than the other candidate schemes.

  • Because of the complexity of the flower design of roll forming process, in which the flat strip is progressively deformed by successive sets of profiled rolls, a computer-aided design system for the flower design has been developed. It is programmed in AutoLISP and DCL(Dialogue Control Language) of AutoCAD. It has been found that the system is helpful in saving the time and effort required to design the flower of the product to be roll-formed.

  • The effect of each tooth for optimal design of Hybrid permanent magnet step motor is presented on this paper. For this consideration, Hybrid permanent magnet step motor was designed in the first consideration tooth structure on the stator and the rotor and poles structure, as number of teeth on the stator and the rotor and slot depth and pitch of teeth, simulated by AutoLISP. During actual rotating, a chracteristic of Hybrid permanent magnet step motor which designed by AutoLISP program is considered. A chracteristic of Hybrid permanent magnet step motor is considered in change each variable, also. As a result, it was found that characteristic of Hybrid permanent magnet step motor changed in accordance with tooth structure and number of teeth and optimal design is possible by AutoLISP.

  • Of several approaches for future Internet, separating two properties of IP address into locator and identifier, is being considered as a highly likely solution. IETF's LISP (Locator ID Separation Protocol) is proposed for this architecture. In particular, the LISP model easily allows for device mobility through simple update of information at MS (Mapping Server) without a separate protocol. In recent years, some of the models supporting device mobility using such LISP attributes have emerged; however, most of them have the limitation for seamless mobility support due to the frequent MS information updates and the time required for the updates. In this paper, PMIPv6 (Proxy Mobile IPv6) model is applied for mobility support in LISP model. PMIPv6 is a method that can support mobility based on network without the help of device; thus, this we define anew the behavior of functional modules (LMA, MAG and MS) to fit this model to the LISP environment and present specifically procedures of device registration, data transfer, route optimization and handover. In addition, our approach improves the communication performance using three tunnels identified with locators between mobile node and corresponding node and using a route optimized tunnel between MN's MAG and CN's MAG. Finally, it allows for seamless mobility by designing a sophisticated handover procedure.

  • This paper describes the development of automatic shape design program for spur gear. It produces automatically third-dimensional surface and solid model used in CAD/CAM system with inputting simple measurements. This program can maximize user's convenience and get surface and solid model quickly as accepting GUI(graphic user interface). Automatic shape design program for spur gear was developed by Visual LISP, a developer program. Besides, a geometrical method and a mathematical algerian are used in this program. Use frequency of a fine spur gear is on the increase recently and manufacture process of this gear is heat treatment after press processing with molding. In this press processing, the upper punch portion of a fine spur gear shape is drafted by CAM. Therefore, estimated that surface and solid model of spur gear used to CAM are needed in this research. In this research, after 2 ㎜ gear was modeled by auto shape design program, the upper punch portion of a fine spur gear was manufactured as giving third-dimensional model to CAM software and then, displayed the result as applying to press process.

  • Design of drawing dies used in real industrial environments. It was designed by CAD software in many small & medium companies, but many products require various types, and sizes. Therefore, many companies are required to reduce process time and design mistakes. In this paper, for the automatic design of drawing dies, Design process considered that easy to team and use. which are used with Visual LISP/DCL language in a commercial CAD package, AutoCAD. It has adopted GUI in design system, and has applied DCL language. The system is based on the knowledge base system which is involved a lot of expert's know-how We have built database of design type and detail sizes. The automatic design system requires basic product type and sizes. Then the system accesses to the database and find out sizes by comparing with input parameters and generate drawing dies file.

  • After investigating repeatedly results obtained through gear stress analysis, we make a determination of an optimal gear shape. But its design process was not only complex but also difficult to get a precise profile curve from operating by hand. In this study, relating shape of gear profile curves was generated automatically with standard spur gear, equivalent helical gear, shifted gear & pinion by using developed program which is using Auto_LISP language in Auto-CAD. This program which can design rapidly gear shapes will successfully support gear designing and manufacturing fur Small & Medium companies.
