In intelligent vehicle highway system, a broadband seamless communication system should be equipped for intelligent highway in order to provide better roadside support for both traditional human operated vehicles and automatic driving vehicles. In this study, wireless 802.11b technology was applied to build up a chained communication network. Concept of roadside data bus was proposed. Experiments demonstrated that it is practical to replace high cost dedicated short range communication technology with 802.11b technology in applications of traffic information broadcasting and collecting. Further applications such as floating car data collection were also discussed.

High resolution data collection using low-cost wireless sensor networks has recently become feasible due to advances in electronics and wireless networking technologies. The geographic grid routing (GGR) protocol described in this paper aims to provide robust task dissemination and data collection from large sensor networks such that the useful lifetime of the network is prolonged. The work builds on a previously developed routing protocol called two-tier data dissemination (TTDD). Our work is differentiated by the use of multiple paths, a more efficient and useful data collection model, and more authentic environmental assumptions, including the presence of asymmetric links. Extensive and realistic experiments were used to evaluate the performance of GGR. The results show GGR to be a highly efficient, scalable, versatile and robust solution.

In this paper, we described in detail about the function definition, architecture and realization strategy of the TinyElf system developed by us. Using Java as a developing tool and RMI as low level communication protocol, we realized the weak transfer function, friendly management interface and system interface. TinyElf supported the system service under different application environment. We finally gave the performance testing result for the system.

There is an increasing demand for use of the Global Positioning System (GPS) to navigate or track objects in the forest. However, objects near a GPS receiver antenna, such as tree leaves and branches, can reflect GPS signals and result in large position errors. Canopies in the forest will also block satellite signals and cause the GPS receiver to stop updating data. This is of practical significance for evaluating the performance of GPS in the forest environment. A field test was conducted to understand how large the position errors are and how long the position updates may be deferred under different levels of canopy densities. A digital camera was used to record the canopies over the test site. Image processing techniques, especially Otsu's algorithm, were used and the canopy density was classified into three levels. The ANOVA was used to analyze the effect of canopy density on the GPS position errors. The result shows that the GPS position errors are significantly different under different canopy density levels. The GPS data-update frequency was also analyzed, and the result indicates that the scheduled position update intervals are lengthened due to the existence of forest canopies.

The design, simulation and implementation of networked predictive control systems is presented in this paper. A novel control strategy of networked control systems, which is termed the networked predictive control, is proposed. The off-line and real-time simulation of the networked predictive control systems is detailed. Also, this control strategy is applied to a servo control system through Ethernet. Various simulation and experimental results demonstrate the operation of the networked predictive control systems.

In the conventional group signature scheme, the group manager can identify the actual identity of the signer. But in some cases, this is not desired. In this paper, we propose a group-oriented anonymous signature scheme, which is unconditionally anonymous, namely, any group member can sign anonymously on behalf of the group, and no one (including the group center) can trace the actual identity of the signer. At the same time, any group member can send subliminal message to the authenticated receiver on behalf of the group. Comparing with the ring signature and 1-out-of-n signature, which can also realize unconditional signer-anonymity, our scheme has the following advantages: the size of signature and public key is independent of the group's number.

The aim of this article is to define a multisensor extended Kalman filter taking context, modelled by fuzzy subsets, into consideration. A nonlinear state model, based on the vehicle dynamics, and three measurement models (GPS, gyroscopes and accelerometers) are developed. In order to take context into consideration, fuzzy validity bounds of each sensor are defined using x/sup 2/ statistics of the normalized innovation given by each sensor. The fuzzification of the validity domain of each sensor is then introduced in the EKF. Simulations are then realized to evaluate the theoretical results. The proposed method is compared to the case when no contextual information is used and when validity bounds are modelled by classical logic. Results show that the fuzzification leads to an improvement of the vehicle positioning.

This paper presents a new assistance tool for the orthopaedic surgeons and their surgeries. In order to have good results, the surgeons have to define the best prosthesis for his patients. Our software is a tool that leads them through the good decision. Its application is done upstream the surgery, during the preoperative stage. From the radiographies of the patients, our application defines the best prosthesis thanks to different available semi-automatic tools. So, we define an original algorithm decision-making aid allowing to manage both the good of an adequate prosthesis and the postoperative study (after the surgery). Our study, has to be flexible (sensory genius) in order to motivate the surgeon with planning and so to allow him to save time during this step.

A reduced iterative decoder for power and bandwidth efficient serially concatenated continuous phase modulation (SCCPM) based on state fusing is proposed in this paper. The proposed algorithm is based on reduced state sequence detection (RSSD) used for CPM and applied to the inner CPM with finite state machine (FSM) structure. System design criterion and performance analysis are listed. Simulation results for binary 3RC signal with h = 1/2 and quaternary 3RC signal with h = 1/2 show that quaternary system provides better performance at the equivalent normalized double-sided bandwidth. The reduced iterative decoder of inner CPM with 4 states for binary 3RC CPM with h = 1/2 is degraded by at most 0.2 dB with respect to its optimal 8 state decoder; the reduced iterative decoder of inner CPM with 16 states for quaternary 3RC CPM with h = 1/2 is degraded by at most 0.5 dB with respect to its optimal 32 state decoder.

The OLAM (on-line analytical mining) model based on agent is proposed in this paper, and a generalized data warehouse built on multi-bases cooperation technique is proposed, which makes DM applicable not only on structured data, but also on complicated data such as text, knowledge and so on. Furthermore, I apply the theory of Union-IADS to construct a data space that comprises the generalized data warehouse mentioned above and data marts. In the end, to build an intelligent CRM system, I integrate the agent-based OLAM model and the data space into a unifying framework, which is a new try on building a CRM system.
