Simulation Based Acquisition(SBA) gains interest from the defense acquisition community. To accomplish SBA efficiently, M&S should be collaborately used in. This paper proposes PBA(PlugIn-Based Architecture) that is a common software development infrastructure and provides reuse mechanism with plugin components. PlugIns are reuse entity possible to plug-in-play statically and dynamically. This architecture supports stand alone simulation and HLA-compliant distributed simulation also.

Simulation Based Acquisition(SBA) which pursues to use M&S in manner of integrated collaboration is being applied in defense acquisition. To accomplish SBA efficiently, reusability, reconfiguration and scalability of M&S components are important factors. To avoid constraints caused by coupling of components, PBA is designed to add and configure components easily by enabling independent interface and interaction among the components and provides common development infrastructure also. And PBA framework is implemented to support the development of a simulator which uses the PBA. It is expected that deployment of PBA framework as common development infrastructure can raise efficiency of M&S works.

This study was conducted to examine the effects of plug tray cell size and growth media on good seedling production of Gerbera hybrida Hort. Seedlings were grown for 60 days in 50, 72, 128, 162 cell trays contanning perlite, cocopeat and perlite+cocopeat(1:1, v/v). Perlite showed higher bulk density than cocopeat and perlite+cocopeat. Total porosity was greater in perlite, cocopeat and perlite+cocopeat in order. Cocopeat showed the highest water holding capacity. Number of leaves were greatest in 128 cell tray containing cocopeat. Leaf area was greatest in 50 cell tray containing cocopeat. Seedling growth was also better in plug tray of bigger cell size. Seedling growth of fresh and dry weight of shoot and root was much better in the growth media of perlite+cocopeat.

Industrial IoT applications, including smart factories, require two problem-solving to build data monitoring systems required by services from distributed IoT sensors (smart sensors). One is to overcome proprietary protocols, data formats, and hardware differences and to uniquely identify and connect IoT sensors, and the other is to overcome the problem of changing the server-side data storage structure and sensor data transmission format according to the addition or change of service or IoT sensors. The IEEE 1451.4 standard-based or IPMI specification-based smart sensor technology supports the development of plug-and-play sensors that solve the first problem. However, there is a lack of research that requires a second problem-solving, which requires support for the plug-in of IoT sensors into remote services. To propose a solution for the integration of these two problem-solving, we present a IoT sensor platform, a service system architecture, and a service plugin protocol for the MQTT-based IIoT application environment.

In this paper, we discuss an effort to develop a multi-agent architecture through which heterogeneous applications communicate and cooperate by means of plug-and play mechanism. Three componets are created in order to challenge the plug-and-play mechanism : meta-information, PnP agent module, and ICM. The meta- information is used to automatically set up a suitable configuration for a new plugged application, eliminating the need for direct addressing among heterogeneous applications. The PnPagent module is a homogeneous controller that operates on an application to ensure that its activities are coordin ated with those of the others within the community, provides a homogeneous communication envelope for all heterogeneous applications. The combination of these three components is used to meet the desire for implementing the plug-and-play mechanism. In this distributed, open architecture, one should be able to simply plug in a new application and it should work.

Component-based development leverages software reusability and reduces development costs. Enterprise JavaBeans (EJB) is a component model developed to reduce the complexity of software development and to facilitate reuse of components. However, EJB does not support component assembly by a plug-and-play technique due to the hard-wired composition at the code level. To cope with this problem, an architecture for EJB component assembly is defined at the abstract level and the inconsistency between the system architecture and its implementation must be eliminated at the implementation level. We propose a component-based application development tool named the COBALT assembler that supports the design and implementation of EJB component assembly by a plug-and-play technique based on the architecture style. The system architecture is first defined by the Architecture Description Language (ADL). The wrapper code and glue code are then generated for the assembly. After the consistency between the architecture and its implementation is checked, the assembled EJB components are deployed in an application server as a new composite component. We use the COBALT assembler for a shopping mall system and demonstrate that it can promote component reuse and leverage the system maintainability.

The ability to rapidly create and deploy new and novel services in response to market demands will be the key factor in determining the success of the future service provider. This goal may be approached from different directions. One of them is an open interface making the functionalities of a network element programmable and usable by outside entities. In this paper, we describe several aspects of this new, hot technical area and introduce related standard activities. In addition, we present a new switching system called MSMP (Multi-Service Multi-Plug-In), which is based on the open programmable interface concept, and describe its architecture and main functionalities of its components.

Recently, Software development method supported CBD is applied with many concern and is researched with part of application and composition based-on architecture effectively use it. Effectively, C2 architecture has been concern with the point of component composition method based-on message driven for supported GUI. But, In case of classified sequence in component and method call method in server component, component must be modified to apply it. Thus, In this paper, Message handling part with a part of C2 architecture change is locate in the message neither component not connector. So, Although method call method it can be composit and operate component for support Plug-and-Play without modification. Also, it's possible the more flexible message handling with parallel composition of component between message without classified sequence.

This experimental study aims to evaluate the impact performance of UHPC exterior panels through high velocity impact tests. The impact performance of UHPC was compared with that of granite in terms of panel thickness, and strain histories were recoded on the rear face of panel specimens. The UHPC turned out to be a good exterior facade material, because the appearance of UHPC is natural enough and impact performance was superior to granite. After colliding, compression pulse reached to the rear face but that pulse was reflected in tension pulse with respect to the free point outside the rear face of the panel. This tension pulse caused the scabbing from the rear side, as the strain histories on the rear face showed three different regions as compression region, steady region and tension region. The shear plug deformation by shear force also was one of the primary reasons for the scabbing based on the observation. Therefore, the scabbing seemed to be affected by both tension and shear forces.

There has been several meaning full efforts to save costs on system development and expand the life-time of a system in changeful IT circumstance. It was a module-based architecture that empower productivity at structured programming era. But it couldn't grow nor evolve, but could raise only calling frequency of module. But OOP or OO-method overcome limit of structured programing by class inheritance and/or overloading and/or over-riding. A component centric architecture, what is mixture of distributed systems, like CORBA or DCOM with OOP, can support not only high reusability or expansion of life-time but also Plug-&-Play between them. To assemble these component to build a new system in easy way, the well-formed specification of a component is highly required. At this study, the enhanced referential component architecture and its UML specification will be suggested.
