This paper solved the problem of how to connect DALI (digital addressable lighting interface) with Internet. A design of embedded DALI dimming controller which based on muC -Linux embedded operation system is presented, the hardware construction using ARM7 MCU and the software conversion between thin TCP/IP and DALI protocol are mainly expounded. The DALI receiving/transmitting circuits and the information frame are also introduced. The signals demonstrate that the DALI controller is designed according to the specification of DALI and improved in some aspects. This controller can be applied in an intelligent remote illumination control system, with the advantage of energy conserving and Internet visiting.

The robot soccer game based complex motion control has been widely studied for the moving object capture and shooting. A position prediction algorithm based on global vision is introduced in order to improve the accuracy and robustness of the vision system for tracking moving objects, including a Kalman filter, a dynamic window and an obstacle avoidance strategy. The novel method is successfully applied to the system for the dynamic capturing and shooting. The simulated experimental results show the proposed technique is effective.

ZigBee technology is a new standard in wireless personal area after bluetooth. After an introduction to this technology, a new wireless meter-reading system based on ZigBee protocol is presented. This system, which is comprised of ZigBee network and database management system, has many important advantages such as low cost, low power consumption, and low date rate.

European installation bus (EIB) is essentially similar to field bus. The communication model used in the system based on EIB protocol is based on the ISO/OSI reference model. The usage of CSMA/CA access mechanism greatly improved the credibility and utilization rate of the bus communication. EIB became dominated in home automation area in Europe because of its excellent performance. In this paper a switch module was developed based on MC68HC05 chip, which successfully communicated with EIB bus. Switch module is significant in scene control. The switch module was tested and communication telegrams were monitored. It made good preparation for further research and development.

Evaluation and optimization method on the operating cost and its saving in Internal Thermally Coupled Distillation Column (ITCDIC) processes for separating non-ideal mixtures is presented. A novel mathematical optimization model with rigorous tray by tray material and energy balances is derived. The optimization and the related process analysis are further carried out. The results reveal that the ITCDIC process of non-ideal mixture possesses an enormous potential of operating cost saving.

The delay-constrained minimum-cost multicast routing problem is known to be NP-complete. Currently many heuristic algorithms have been proposed, most of which are centralized, or centralized in nature. A completely distributed scheme based on ant colony optimization is proposed. In this scheme, no core node with the whole network topology information exists and the ants only use the local information of their current nodes to find the destinations. Combined the characteristics of multicast routing, the algorithm was improved, which accelerated the convergence speed and enhanced the quality of solution. The proposed scheme is easy to realize by three types of ants with simple structures. The scheme is loop-free and has small overhead compared with the flooding method. Simulation results show that the scheme is an effective distributed approach to multicast routing decision with delay constraint.

Ant colony optimization (ACO) algorithm has the powerful ability of searching the global optimal solution, and backpropagation (BP) algorithm has the feature of rapid convergence on the local optima. The proper hybrid of the two algorithms (ACO-BP) may accelerate the evolving speed of neural networks and improve the forecasting precision of the well-trained networks. ACO-BP scheme adopts ACO to search the optimal combination of weights in the solution space, and then uses BP algorithm to obtain the accurate optimal solution quickly. The ACO-BP and BP algorithms were applied to the problems of function approaching and modeling quantitative structure-activity relationships of Herbicides. Experiment results show that the proposed ACO-BP scheme is more efficient and effective than BP algorithm. Furthermore, ACO-BP reliably performs well when the number of hidden nodes varies.

Real-time video streaming over the Internet often suffers from a kind of congestion on the bottleneck links caused by the video stream itself, a phenomenon so called self congestion. The motion compensation based video coding algorithms make video streams of variable bit-rate nature, which cause burst traffic, extra transmission delay, and even queue overflow of the bottleneck link and video data loss at the receiver thereafter. This makes self-congestion control a necessity for streaming video. In this paper, a sender-side optimized congestion control scheme for MPEG-4 fine granularity scalable (FGS) coding video stream is proposed. The scheme not only attempts to minimize the received video distortion at the receiver side, but also tries to maintain a smooth transmission rate in the network. The simulation results show the effectiveness of the proposed scheme in terms of the received video quality, the smoothness of video transmission rate, and the variance of the size of the bottleneck queue.

Firstly the increasing domestic demand and the developing situation of dejectas collecting device were analyzed briefly. A new design of the vacuum type dejectas collecting device was contrived. Then its structural characteristics, operation mode and testing were introduced.

With the rapid development of computer, communication, network and economics, home automation (HA) is stepping into our daily life. European Installation Bus (EIB) is an important standard in HA area. The first section describes the framework and the second section illuminates how EIB works. The following section provides an overview of EIB-IDE, the EIB-integrated development environment, which is the most effective tool to develop EIB application module. Finally the development process is demonstrated by an example of a simple application for one of the possible target devices.

Inherited from the successful design of the large paperless recorder, the intelligent small paperless recorder has a modular structure. It also employs the same data acquisition module as the large paperless recorder does. It has a menu driven GUI (full Chinese language), eight multi-purpose input channels (all user configurable), 16-channel relay outputs and 2-channel analog outputs (V/mA). Though a MCS51 based MCU is used as the main controller, the limitations of 64K RAM and ROM of this kind of MCU have been conquered through page mapping and code banking technologies. The paper describes how to accomplish this breakthrough from the aspects of hardware and software design.
