In order to compete in the global market, engineering organizations are under increasing pressure to design, develop, and deploy products in the market place as quickly as possible with first time quality. In order to achieve these objectives, it is necessary to streamline the design and development process, namely, “transfer of analytical design of Intelligence to Mechatronics intelligence” in an...
This paper mainly describes the vehicle traveling data recorder system based On ARM. It selects the huge flash rom memory as the memorizer. It collects and stores the real-time data every second by timer interrupt, and uses µC/OS-¢ò, an embedded operating system, to design the software. Computer can communicate with microchip by com interrupt and store the data in the hard disk by binary system.
Traditionally, real-time systems managed data in application dependent structures. As real-time systems evolved, applications became more complex and required access to more data which are being provided by data base management systems. Currently, there has been interest in merging database and real-time technology. The resulting integrated system, which provides database related operations with real-time...
In order to solve the current situation of the present domestic gas station with low level of management, information management system of gas station is developed. The system get the oiling data through the tanker controller by computer, the operations of query, addition, deletion, modification are realized by using the foreground program to background database, the oiling data can not be modified...
Musical instruments have evolved manifolds in the past 50 years. From simple percussion and acoustic instruments, they have evolved into their electronic counterparts. With this evolution and the fact that these counterparts are in extensive use these days, comes the need to process these input electric signals using computers to produce the desired results and outputs. The input signals can be processed...
Research in surgical robots often calls for multi-axis controllers and other I/O hardware for interfacing various devices with computers. As the need for dexterity is increased, the hardware and software interfaces required to support additional joints can become cumbersome and impractical. To facilitate prototyping of robots and experimentation with large numbers of axes, it would be beneficial to...
The authors introduced the development and conception of data warehouse and database and research the relationship between database and data warehouse, and have studied the difference between their technology. At last discuss the combination and application of the database,and date warehouse technology.
Users need to record whole motions on their computer screens in many applications, such as distance learning, distance conference, thin client, share desktop and remote control etc. In order to conveniently use these applications, a problem, called asymmetric screen resolution (ASR), needs to be solved. The ASR problem means that the resolution of a remote computer is different from that of a client...
In order to resolve crashed accidents caused by fatigue or drowsiness various fatigue detecting algorithms are investigated. Aiming at the needs of large data, high transfer rate and complex operation, in this paper, we design a fatigue detection algorithm based on PERCLOS, moreover, design AVT Guppy F-080 C camera and 1394 cards as the core hardware system. The system can meet the real-time video...
Based on the research of technology that through which virus attacks the application, we find that an important reason of the application vulnerable to be attacked is the lack of effective access control to application files. In view of this problem, this paper build a protection model of Application files, combined with system snapshot technology. This model can give the application files real-time...
Based on the virtual realistic technical, the text discussed the feasibility of the virtual realistic technique can be applied to tour system constructive. Finally, on the foundation of the Earth platen, inquired the feasibility and key technique of virtual realistic technique in the travels system tapping.
Real-time microkernel implementation details and concepts for small-memory embedded system are presented in this paper. Based on the analysis of the standard embedded system functional specification, new hybrid scheduling algorithm was introduced. Proposed scheduling algorithm is tuned for task model defined for standard embedded application and combines the advantages of static and dynamic scheduling...
Recently, new services based on a real-time information related with human activities have become available over the Internet. An infrastructure of such a service must be able to accommodate a large number of real-time content distributions and must allow the subscribers to start receiving the desired contents quickly. In this study, a new content distribution system using peer-to-peer technologies...
An attempt is made in this paper to summarize the state of the art in the interaction between the ICT (information communication technologies) that becomes ubiquitous and the electrical power production and distribution. Both are considered to have a difficult task to fulfill enormous rise of demand that is becoming above all expectations. In the same time they technologically interfere in the sense...
Due the significant need for real-time anonymization we propose Real-time Netshuffle [1]; a complete graph distortion technique designed to mitigate risk to inference attacks in traffic anonymization. Real-time Netshuffle provides an additional layer of security, in concert with other on-line traffic anonymization techniques, while imposing only minimal damage to the empirical value of the data.
Fault injection methods have long been used to assess fault tolerance and safety. However, many conventional fault injection methods face significant shortcomings, which hinder their ability to execute fault injections on target real-time safety-critical systems.
The real-time rendering of large-scale terrain has been widely used in driving simulation, virtual battlefields and 3D games. Large-scale terrain holds huge geometric and textural data. How to generate and render large-scale terrain in real time with limited computing resources is a big challenge. Different from the previous out-of-core terrain roaming methods which are based on complex scheduling...
In this paper, to solve the problems that matching an image through the SURF (Speeded Up Robust Features) algorithm spends too much time, a novel image matching algorithm to improve surf will be introduced. While surf is known to be strong but computationally still expensive, it has not attained real-time performance yet. Thus this algorithm is based on the heavily modified SURF feature descriptors...
Rapid prototyping aims to provide rapid design, validation and testing methods for physical prototypes. The paper designed rapid prototyping simulation system based on RTX real-time kernel and VPM (Virtual Prototyping and Modeling) development tools, and discussed the system's operation environment, system architecture, system components and major functions. Through combination of VPM modeling and...
The paper introduces a design scheme to quickly build data acquisition system based on SoPC and LabVIEW technology. The slave computer of the acquisition system in the design adopts the EP3C10 chip of the CycloneIII series produced by Altera as the main control chip for digital control on A/D converter chip CS5550, digital signal after A/D conversion will be sent to the host computer through RS232...
