Reverse logistics is the process of planning and controlling the recovery flow of end of life products Industry is increasingly being confronted with the need to solve several reverse logistics issues because of not only stringent environmental legislatio

  Because of different hardware specifications, there are no unified protocol commands to use with various kinds of RFID readers. The current commercial RFID middlewares do not satisfy the various requirements from users to support business process logic

The development of information technology, which has brought the fusion of broadcasting and telecommunication, wire and wireless communication and voice and data, is developing new fusions like home network which is composed of IT, construction, and home appliances. This trend is considered to continue and to make other new fusions based on previous ones. In this study, we investigate the roles of RFID middleware by identifying the relationships between the new expected fusions and RFID.

This paper deals with the middleware development for real time data processing using ubiquitous RFID(Radio Frequency Identification). This middleware system supports the real time data gathering, filtering, and collaborative operations within SCM. We expect to decrease the data processing cost and to upgrade the status of RTE(Real Time Enterprise) and competitive power of company.

A URC, which is a Ubiquitous Robot Companion, provides services to users in ubiquitous computing environments and has advantage of simplifying robot's hardware and software by distributing the complicated functionality of robots to other system. In this paper, we propose SOWL, which is a software architecture for URC robots and a mixed word of SOMAR and CAWL. SOWL keeps the advantages of URC and it also has the loosely-coupled characteristics. Moreover it makes it easy to develop of URC robot software. The proposed architecture is composed of 4 layers: device software, robot software, robot application, and end user layer. Developers of the each layer is able to build software suitable for their requirements by combining software modules in the lower layer. SOWL consists of SOMAR and CAWL engine. SOMAR, which is a middleware for the execution of device software and robot software, is based on service-oriented architecture(SOA) for robot software. CAWL engine is a system to process CAWL which is a context-aware workflow language. SOWL is able to provide a layered architecture for the execution of a robot software. It also makes it possible for developers of the each layer to build module-based robot software.

The UPnP is middleware architecture that supports dynamic distributed computing environment. It has many good features for possible use as middleware in robot system integration. There is a need for bulky binary data transmission between distributed robot S/W components. Since the UPnP utilizes SOAP protocol for message transmission, however, it is not efficient to send bulky binary data. In order to overcome this weak point, this paper proposes UPnP-MTOM, MTOM (Message Transmission Optimization Mechanism) implementation over UPnP, as an efficient way for bulky binary data transmission with UPnP messages. This paper presents our implementation method and experimental results of the UPnP-MTOM implementation.

This paper describes a network framework that support network based humanoid. The framework utilizes middleware such as CORBA (ACE/TAO) that provides PnP capability for network based humanoid. The network framework transfers data gathered from a network based humanoid to a processing group that is distributed on a network. The data types are video stream, audio stream and control data. Also, the network framework transfers service data produced by the processing group to the network based humanoid. By using this network framework, the network based humanoid can provide high quality of intelligent services to user.

대부분의 디자이너는 3DS MAX와 같은 전문 3D 애니메이션 저작도구를 사용하여 수작업으로 애니메이션을 제작한다. 이 방법은 많은 시간과 노력을 필요로 하며, 애니메이션 캐릭터들이 서로 상호작용 할 수 없다. 이를 개선하기 위해, 본 논문에서는 3DS MAX플러그인 형태의 인공지능 미들웨어를 설계하고 미들웨어에 필요한 인공지능 표현 구조와 내부 처리 방안을 제안한다. 제안 방법은 캐릭터가 보유할 인공지능 요소를 도형과 선분으로 그려 표현하는 방법으로 캐릭터의 인공지능 구조를 제작한다. 실험을 위해 기존 방법과, 제안하는 방법을 사용하여 동일한 애니메이션을 제작하고 작업량을 측정하였다. 실험 결과 소규모 작업에서는 기존의 방법과 비슷하거나 작업량이 많으나, 대규모의 작업에서는 기존 방법에 비해 최대 43%의 작업량 감소를 확인하였다. 본 논문에서 제안하는 방법을 사용하면, 애니메이션에서 캐릭터간의 상호작용이 가능하며 작업량 감소 효과를 얻을 수 있다.
