The need for efficient public transportation system such as buses is rapidly increased due to the increasing in population, the passengers need to know the accurate arrival time of the particular bus to particular station and then plan their journey from their home. Fuel monitoring have been the major problem that most of bus companies looking to solve. This paper developed a bus tracking and monitoring...
The Trigger and Data Acquisition (TDAQ) and detector systems of the ATLAS experiment deploy more than 3000 computers, running more than 15000 concurrent processes, to perform the selection, recording and monitoring of the proton collisions data in ATLAS. Most of these processes produce and share operational monitoring data used for inter-process communication and analysis of the systems. Few of these...
We extend previous work on formalising design patterns to start the development of security patterns for Grid systems. We demonstrate the feasibility of our approach with a case study involving a deployed security architecture in a Grid Operating System called XtreemOS. A number of Grid security management capabilities that aid the secure setting-up and running of a Grid are presented. We outline...
Demands on security, safety, and environmental protection in worldwide shipping is steadily increasing. Shipboard broadcast transponders based on the automatic identification system (AIS) can be easily detected close to coast or waterway areas. Satellite-based AIS receivers detect globally but are limited in high density traffic areas. In this paper, a new possibility for worldwide AIS detection via...
As for the complex electromagnetic environment simulation, this paper propose a parallel computing system based on file segment, this system offers the developer a flexible interface. The paper describes the database design in detail, analysis the performance of the database, therefore offers a base for the complex environment simulation.
A Virtual Electronic Patient Record (VEPR) has been deployed at Hospital de S. João since 2005 that retrieves and integrates clinical record data. One of its modules is a MultiAgent system for Integration of Data (MAID) that provides automatic report retrieval from departmental systems. The currently deployed MAID uses a static interval for the scheduling of report references retrieval actions. As...
RFID technology is an automatic identification technology with low cost tags and high read reliability. This paper presents a new framework for building the general FRID application system base on the RFID and J2EE technology. The J2EE and EJB technology is applied to offer a framework to construct enterprise FRID system structure. The ORM technology is used to separate business and storing; the AOP...
Based on the platform of 3GS (GPS/GPRS/GIS), a method of designing the MIS of patrol police is proposed in this paper which offers a convenient and real-time monitoring platform for the administration of patrol police. The proposed method can extent the monitoring range and promote the supervising efficiency of patrol police. Oracle9i adopted in this paper to save the spatial and attributive data...
Efficient intrusion detection system (IDS) management is a prominent capability for distributed IDS solutions, which makes it possible to integrate and handle different types of sensors or collect and synthesize alerts generated from multiple hosts located in a loosely coupled environment. Extensibility is the main requirement for most of IDS management systems. The concept of virtualization has been...
Base on the requirements of RFID on identifying object, the paper researches on general software architecture on the application system. We use middleware and layer design to lower the coupling; use ORM technology to separate business and storing; use AOP technology to focus on business; use IOC technology to improve testing, use cleaning method that optimizes the overall accuracy adjusted cleaning...
With the development of high rate data transmission technology via distribution line communication, the electric power, data, voice and video can be transferred in the same electric power distribution network, and the technology will be put in operation widely in the future. However the traditional technology of power line communication is not adaptable to the complex and harsh environment of distribution...
