Embedded system developers use design and testing tools to make their product faster. Previously developed a virtual development environment for embedded software (VDEES) using open source software, mainly the SID simulation framework for a simulator engine and the Eclipse platform for a development platform. VDEES enables developers to develop SID Component in C++. A bridge module for developing SID Component in Java has been developed and available. However, using this module, developers have to build their SID Java component from scratch. In this work, we developed SID Java Component Builder Plug-in as an additional features to VDEES. This tools enables developers to build SID Component in Java faster and easier.

In order to reduce the cost of software maintenance including software modification, we suggest the object oriented program with checking the version of application program using the Java language and the technique of executing the downloaded application program via network using the application manager. In order to change the traditional scheduler to the application manager we have adopted the Xlet concept in the nuclear fields using the network. In usual Xlet means a Java application that runs on the digital television receiver. The Java TV Application Program Interface(API) defines an application model called the Xlet application lifecycle. Java applications that use this lifecycle model are called Xlets. The Xlet application lifecycle is compatible with the existing application environment and virtual machine technology. The Xlet application lifecycle model defines the dialog(protocol) between an Xlet and its environment

현재 PC환경 뿐만 아니라 모바일 환경, 임베디드 환경에서 딥러닝 모델을 구동하기 위한 많은 연구들이 진행 중에 있다. 본 연구에서는 완성된 딥러닝 모델을 구동하는 환경을 Java로 구현하여 개발 접근성을 높이고자 한다. 이미지, 영상처리를 위해 OpenCV를 사용시 C++ API문서는 보편화되어있는 반면에 JavaCv API 문서는 그렇지 못하다. 그러나 모바일 개발 환경 특성상 Java언어로 작업한 코드를 안드로이드 스튜디오에서 작업 시 그대로 가져올 수 있어 개발이 용이하다. 모델 구동을 위한 전반적인 이미지 처리 및 작업환경을 개발하였다.

This paper describes the development of an automatic dependent surveillance system(ADS) with Java on Web environment. The ADS consists of a server module and a client one. The server module performs a database server for gathering GPS data from airplanes. It also dose an Web server function for sending Java applet to clients. The applet enables each client to obtain the current flight information from the server via the Internet without a special client software. This client-server based ADS with Java environment has several advantages over other systems. One is not to need for installing special client software on each client system. The other is its simplicity on system maintenance. The reason why it has simplicity is to require only server program modification including the applet without updating client software. After testing the ADS system with the flight information of a Mooney, we can show that the prototype system can be a candidate for developing commercial products.

Current research for software architecture views and models a software system as a set of components and connectors. Components are abstractions of system level computational entities. Connectors are abstractions of components interrelationships. In this paper, we focus on connectors for the JavaBeans-based systems that are built using object integration technologies like CORBA. We present connector model in JavaBeans-based system for object-oriented component integration. We start with a discussion of related work of software architecture research and object-oriented modeling that focuses on the description of component collaborations. We propose connectors as transferable abstractions of system level component interconnection and inter-operation.

An important technical issue in recent software development is to make needed software by the composition of components that are assemblable, and configurable, and independently extracted. The main advantage of component-based software development is reducing development time and cost. It is more cost-effective in development time to use components that are already developed than developing from scratch. There are two ways of component-based software development: one is to compose self-developed components, and the other is to by the components developed by third-parties and compose them. In the second case, existing non component programs must can be used for reuse in the component development. In this paper, we approach two methods for increase of reusability of Java program. First, we suggest the technique of extracting the elements suitable for the Beans component model from Java program, and then we show a process and a guideline of converting the extract elements into the Beans component model. Second, we suggest a technique of automatically extracting component information from the Java Beans component, expressing them in XML, its is possible to reuse the efficient component environment.

This Current research for software architecture views and models a software system as a set of components and connectors. Components are ions of system level computational entities, connectors are ions of component interrelationships. In his paper, we focus attention on connectors for the Java Beans-based systems that are built using object integration technologies like CORBA. We present connector model in lava Beans-based system for object-oriented component integration. We start with a discussion of related work of software architecture research and of Object-Oriented modeling that focuses on the description of component collaborations. We propose connectors as transferable ions of system level component interconnection and inter-operation. Connectors are architectural ions of component coordination in the architecture of a system only. Connectors describe a collaboration rationale for component adaptations, which are then modeled in the concrete architecture of a system.

Object technologies like the OMG's CORBA are enabling technologies the aim to facilitate integration implementation of diverse software components in distributed. heterogeneous environment. CORBA and similar object integration technologies define a standard component interconnection and inter-operation model , promote object-oriented principles to encapsulate incompatible component implementations. In this Paper. we present a connector model for software architectural representation of complex component collaborations. Our Connector model is base on research in software achitecture and object-oriented modeling. and part of a design framework for modeling component-based system. We believe the connector concepts to be vary benificial for a clear expression of dependencies between multiple component in Java Bean-based system.

Sensor network consists of a large number of sensor node distributed in the environment being sensed and controlled. The resource-constrained sensor nodes tend to have various and heterogeneous architecture. Thus, it is important to make its software environment platform-independent and reprogrammable. In this paper, we present BeeVM, a Java operating system designed for sensor networks. BeeVM offers a platform-independent Java programming environment with its efficiently executable file format and a set of class APIs for basic operating functions, sensing and wireless networking. BeeVM's high-level native interface and layered network subsystem allow complex program for sensor network to be short and readable. Our platform has been ported on two currently popular hardware platforms and we show its effectiveness through the evaluation of a simple application.
