This paper proposes a small, power saving embedded Web server for home appliances. The proposed device operates with a real-time operating system on a 32 bit RISC microprocessor. A TCP/IP protocol stack, HTTP, FTP, SNTP server and client applications were developed. The prototype server requires one fortieth the power of a general server using a PC. The software resources are about 1.8 MB. Demonstrations...
To ensure the safe and stable operation of wind farms, it is necessary to monitor the various operation parameters real-time. This paper introduces the Embedded Web Server technology; using DSP+ARM double CPU structure, designs and realizing the wind farm remote monitoring system based on the Embedded Web Server.

A number of different approaches exist to deliver multimedia content to the end-user through the Web. Within classic client-server architectures, three main media delivery methods exist: HTTP download, real-time streaming, and HTTP streaming. The latter combines the advantages of both the HTTP download and the traditional streaming approach. In this paper, we provide an overview and analysis of two...
The Green Ajax outperforms than the classical Ajax. It can decrease the bandwidth consumption to/from the web server. In the previous research, the Green Ajax results the best performance for the case of random and unpredictable update time on the web server. However, from practical point of view the web server will not always update at the random pattern of time. In this research, the web server...
Web access logs contain information which can be converted to represent the access history of individual users. A large number of essential attributes can be extracted from the access history. For example, the access counts of each webpage, the occurrence of different webpage access sequences and the time spent between consecutive accesses. Each of the above attributes represents a dimension in the...
The classic web applications usually need a lot of bandwidth to provide the rich user interfaces. Since Ajax [8] was introduced, it has reduced the web server load and the data transfer to/from users' computers. By using Ajax, only a specific part in the web page can be requested to the web server [6]. However, it still cannot provide the real time data updating. The common approach to provide the...
Through introducing Internet into control network, it is possible to break through the spatio-temporal restriction of traditional control network and effectively achieve remote sensing, monitoring and real-time controlling for equipments In this paper, a remote embedded Monitoring system based on Internet is presented. Firstly, the three-layer architecture and workflow of remote monitoring system...
Clients can exchange data with embedded device where Web server is transplanted. In order to observe the state of the device and display it in the form of dynamic history curve, this paper has adopted two methods to get the real-time data of the embedded device and display the curve. One uses JavaScript cooperating with VML (Vector Markup Language), the other uses Applet. The two methods both have...
In this paper, we investigate a real-time estimation system in HLA-based simulation systems. The use case and architecture of the system are analyzed. The main parts of the system, including the evaluation agent, the databases and the web-based result display systems are introduced. Towards the evaluation agent, the interface relationships are depicted. Then the structure and principle of evaluation...
A real-time monitoring system for monitoring the production of infusion solutions in a pharmaceutical plant is introduced. The main features of the system are its ability to stratify the measuring data into numerous dimensions, focus on visual presentation of the quality related information, such as the input volume of distilled water and their temperature. The realinfo configuration software based...
In order to meet the needs of monitoring and recording telephone calls and strengthen supervision over safety-production for the control center of organizations, the Web-based VoIP recording management system is developed. This system realizes several management modules, including management of device, channel, call record, recorded files, system setting, and the system auxiliary functions for user...

The node features two communication interfaces-CAN (Controller Area Network) and Ethernet, equipped with high-layer protocols MicroCANopen and HTTP Web server over TCP/IP. Monitoring of application process data objects PDO of the MicroCANopen protocol using...
We describe a platform for performing text and radiology analytics (TARA). We integrate commercially available hardware and middleware components to construct an environment which is well-suited for performing computationally intensive analyses of medical data. The system, termed a "medical analytical platform," adopts a client-server approach for the display and processing of radiology...
In this paper, we present the principles of a low-operational-cost but flexible Internet-based data-acquisition system. The main core of the system is an embedded hardware running a scaled-down version of Linux: a popular choice of operating system for embedded applications. The embedded device communicates through general packet radio service (GPRS), which makes it accessible from anywhere in the...
