Development of electronic warfare(EW) software has become increasingly challenging due to stricter regulations, shorter development cycles, and increased reliability testing. Consequently, software development often proceeds without proper architecture design, which can lead to missing critical quality requirements and potential system redesigns. In this study, we propose using Attribute-Driven Design(ADD) 3.0 to design software architecture specifically tailored for EW systems, enabling a more systematic approach to address quality requirements. The paper presents an overview of EW software and ADD 3.0 methodology, followed by an analysis of the architecture design results using static and dynamic views. The paper concludes by discussing the effectiveness of the proposed architecture design.

According to development of wireless communication technologies, we need not only high data rate but low data rate system of low power consumption. This low data rate system is utilized in the field of home automation, health care, sensoring and monitoring, etc. IEEE 802.15.4 LR-WPAN system is the best choice for realizing ubiquitous networking system. In this paper SoC Architecture for IEEE 802.15.4 Low Rate WPAN is designed. IEEE 802.15.4 Low Rate WPAN system serves the functions and realization of home area network. We propose the SoC architecture for 868/915MHz frequency band of IEEE 802.15.4 Low Rate WPAN system. The key issue is to design SoC architecture which provides the function of Low Rate WPAN system to meet the requirement of IEEE 802.15.4 standards.

This study aims to optimize an arrangement of ship compartments with knowledge-based systems. Though great attention has been shown to the optimization of hull forms in recent years, the study on arrangement design optimization has received relatively little attention. A ship is both an engineering system and a kind of assembly of many spaces. This means that, to design an arrangement of ship compartments, it is necessary to treat not only geometric data but also knowledge on topological relations between spaces and components of a ship. In this regard, we select a suitable knowledge representation scheme for describing ship compartments and their relations, and then develop a knowledge-based system using expert system shell. This new approach is applied to create design variations for optimization on an arrangement of a pressure hull of a submerged vehicle. Finally, we explicate how our approach improves the design process.

With the advance of Smart TV technologies, TV watchers can enjoy the Internet and games while watching TV programs. Besides retrieving with some keywords in the Internet, people may want to access local information such as notifications from town, messages from children's schools, shopping information from local marts, and even reminder messages for visiting from hospitals while watching TV without using web-browser. In this paper, we introduce the daily life notification service scenarios and its functional and non-functional requirements. Furthermore, we also propose a system that provides the notification services, consists of smart TV apps and server systems. We also introduce the system architecture and the component design of the system. Our work will help smart TV service developers because this paper will give them some service scenarios, requirements, and system architecture and its component design.

함정은 일반성능, 특수성능, 탑재장비 성능과 관련된 수많은 요구사항이 있으며, 장기간에 걸친 설계 및 건조기간 동안 요구사항은 각 시스템에 반영되고 구현되어야 한다. 요구사항은 설계기간 동안 작성되는 도면, 보고서, 제안요청서, 사양서 등 다양한 문서들을 통해 구체화 된다. 그러나 함정과 같은 복합시스템의 경우 이런 산출물을 통해 요구사항 추적성을 유지하며 요구사항을 관리하는 것에 많은 어려움이 따른다. 함정의 설계 및 건조기술은 오랜 역사 속에 발전되어 왔기 때문에 기존의 문서기반 설계 방식에 익숙하지만, 각종 설계 산출물과 요구사항, 그리고 시스템의 기능, 물리 아키텍처 간 추적성 관리는 어려움이 있다. 함정의 기본설계는 함정 제원 및 성능, 탑재장비 선정 및 배치, 연동 등을 확정하는 중요한 단계이며 시스템 아키텍처 설계 구현을 위한 구체적인 적용 방법 연구를 통해 변화가 요구된다. 따라서 함정 기본설계 단계에 적합한 요구사항 설계 적용을 위한 시스템 아키텍처 설계 방법 연구가 필요하다. 본 논문에서는 요구사항으로 부터 시스템 아키텍처 설계를 수행하고 SE 기반 기술검토 프로세스를 통해 확인하는 방법을 연구하였다. 잠수함 시스템 아키텍처 설계를 위해 요구사항 분석, 아키텍처 설계, 설계 실행 및 통합의 각 단계별 세부 수행사항과 내용을 제시하였다. 이를 통해 효과적인 시스템 요구사항 개발 및 아키텍처 설계가 가능하였으며, 단계별 추적성 관리, 요구사항의 확인 측면에서 효과적임을 확인하였다. 향후 잠수함을 비롯한 다양한 함정에 제시한 프로세스 적용이 가능할 것으로 판단된다.

In the case of designing autonomous robot architecture using deliberative and reactive control methods, we can use mixed hybrid form as well as purely reactive scheme or purely deliberative scheme respectively according to its own goal and environment within the robot operates, It needs time and endeavors to design robot control architecture in either case above. In our research, we implemented a 3-dimensional robot simulator in order to help designing reactive/deliberative autonomous robot control architecture by offering methods which is capable of selecting design parameters and confirming its performances. It can be used, of course, to design purely reactive or purely deliberative architecture. The architecture and performance of simulator is shown and a sample hybrid robot architecture designed with the simulator is introduced in this article.

A next generation small satellite HAUSAT-1, the first picosatellite developed in Korea, is being developed as one of the international CubeSat program by Space System Research Lab. of Hankuk Aviation University. A fault-tolerant incremental design methodology has been addressed in this paper. In this study, the effect of system redundancy on reliability was in details analyzed in accordance with the implementation of fault-tolerant system. Four different system recovery levels are proposed for HAUSAT-1 fault-tolerant system optimization. As a result, the HAUSAT-1 fault-tolerant system architecture design and reliability analysis has acquired about 11% reliability improvement.

Personal Robot System being developed is designed to module-based system architecture for supporting internal devices have variable system platforms, environments, networks. For supporting development environment, integrating remote services, managing the interoperation among internal modules on this system design, a well-designed object oriented middleware is needed significantly. There are already some middlwares like DCOM, CORBA, UPnP, JINI, OSGi, etc. But they have some limitations to applying to Personal Robot in variable side view. We are researching for a suitable design scheme to require low system resources, to guarantee realtime services as possible, and to implement easily. In this paper, we suggest a middleware architecture have goals that are simple, light, and object oriented, so that can be used at diversity devices in Personal Robot System.

All current shipyards are using the customized CAD/CAM programs in order to improve the design quality and increase the design efficiency. Even though the data structures for ship design and construction are almost completed, the implementation related to the ship design processes are still in progress so that it has been the main causes of the bottleneck and delay during the middle of design process. In this study, we thought that the hole-plan system would be a good example which is remained to be improved. The people of outfitting division who don't have direct authority to edit the structural panels, should request the hull design division to install the holes for the outfitting equipment. For acceptance, they should calculate the hole position, determine the hole type, and find the intersected contour of panel. After consideration of the hull people, the requested holes are manually installed on the hull structure. As the above, many processes are needed such as communication and discussion between the divisions, drawings for hole-plan, and the consideration for the structural or production compatibility. However this iterative process takes a lot of working time and requires mental pressure to the related people and cross-division conflict. This paper will handle the hole-plan system in detail to automate the series of process and minimize the human efforts and time-consumption.
