The real-time system is now used on many fields, such as telecommunication, military, information system, evenmedical to get information quickly, on time and accurate. Needless to say, a real-time system will always considerthe performance time. In our application, we define the time target/deadline, so that the system should execute thewhole tasks under predefined deadline. However, if the system failed to finish the tasks, it will lead to fatal failure.In other words, if the system cannot be executed on time, it will affect the subsequent tasks. In this paper, wepropose a real-time system for sending data to find effectiveness and efficiency. Sending data process will beconstructed in MATLAB and sending data process has a time target as when data will send.

Structured Analysis

This paper combines the characteristics of real-time embedded systems and the real-time operating system to propose a software engineering method and process which bases on the function structured analysis and task structured design. First in the process of structured analysis based on the Hatley-Pirbhai method, extracting and sorting out the data flow and control flow according to the functional requirements of the system, analyzing and processing the functions of the system, the dependency among the functions and the timing sequence, and then realizing the design of the specific functions of the system, next achieving the structural design through the improving method, it also simplifies the system design processes. At this time, just need to analyze and divide the processing which is obtained from the structural analysis to get the specific task, design the interfaces among the tasks and also every task to get the new design method of the embedded real-time operating system, which also solves hard issue of the traditional method which is the weak extracting and developing iteration in the embedded real-time system.

Behavior Based

Implementing a robot controller that can effectively manage limited resources in a deterministic, real-time manner is challenging. Behavior-based architectures that decompose autonomy into levels of intelligence are popular due to their robustness but do not provide real-time features that enforce timing constraints or support determinism. We propose an architecture and approach for using the real-time features of the Real-Time Specification for Java (RTSJ) in a behavior-based mobile robot controller to show that timing constraints affect performance. This is accomplished by extending a real-time aware architecture that explicitly enumerates timing requirements for each behavior. It is not enough to reduce latency. The usefulness of this approach is demonstrated via an implementation on Solaris 10 and the Sun Java Real-Time System (Java RTS). Experimental results are obtained using a K-team Koala robot performing path following with four composite behaviors. Experiments were conducted using several task period sets in three cases: real-time threads with the real-time garbage collector, real-time threads with the non- real-time garbage collector, and non-real-time threads with the non-real-time garbage collector. Results show that even if latency and determinism are improved, the timing of each individual behavior significantly affects task performance.

AbstrakPendampingan pelayanan oleh case manager diawali dengan skrining pasien, namun metode skrining dan pelaporan hasil skrining secara manual cendrung kurang efektif dan kurang efisien. Inovasi ini bertujauan untuk mengembangkan sistem skrining yang lebih efektif dan efisien melalui yaitu skrining berbasis sistem informasi manajemen. Metode yang digunakan adalah prototyping model. Hasil inovasi ini adalah sebuah prototipe sistem informasi manajemen skrining case manager berbasis web dan android. Aplikasi ini digunakan oleh perawat yang melakukan skrining dan case manager yang melakukan verifikasi hasil skrining. Dengan sistem update yang real time, aplikasi ini sangat bermanfaat untuk meningkatkan efektifitas dan efisiensi skrining dan pelaporan hasil skrining case manager di rumah sakit. Rumah sakit diharapkan dapat menerapkan sistem ini untuk menigkatkan efektifitas dan efisiensi layanan khususnya case manager.Kata kunci: case manager, prototyping model, sistem informasi manajemen Development of Case Manager Screening Management Information System at RSUP Persahabatan Jakarta AbstractService assistance by the case manager begins with screening patients, but the method of screening and reporting the results of manual screening tends to be less effective and less efficient. This innovation aims to develop a more effective and efficient screening system through management information system-based screening. The method used is the prototyping model. This result is a prototype of a web-based and android case manager screening management information system. This application is used by nurses who conduct screening and case managers who verify the results of screening. With real time system updates, this application is very useful for improving the effectiveness and efficiency of screening and reporting the results of case manager screening at the hospital. Hospitals are expected to implement this system to improve the effectiveness and efficiency of special case manager services.Keywords  : case manager, prototyping model, management information system

To resolve the color-register problem on web-press machine, a kind of networking register system was presented. Firstly, a special diamond mark was designed, which is easier to be embedded. Secondly, the high-speed cameras with external trigger signal were adopted to capture mark images under the control of synchronous encoder unit, at the same time the real-time deviation of color was obtained by analyzing the mark image. Lastly, the data of color deviation were transmitted to the press system over Ethernet. Thus, a close-loop and real-time system was built. Especially, an Ethernet solution for the press machine with many towers was proposed. According to the actual customer’s reports, waste of newspaper decreases greatly, in addition, print quality and print efficiency are both promoted.

OSEK OS is a very static system. all of the functionality of the system is already defined in the design phase. During Operation, the change of the system functionalities does not occur. Thus, we propose a optimized implementation of the scheduler for OSEK OS based on predictable system features to improve the functionality of the Real-time system.
