In the given paper principles of organization of neural-like system consisting of a matrix of photoelectric cells are represented. The practical realization of this system allows to obtain a parallel processing of an optical information for environmental physical field monitoring. A computer model of the feed-forward neural network with the hidden layer is developed to reconstruct physical field investigated by the fiber-optic measuring system. The Gaussian distributions of some physical quantity are selected as learning patterns. Neural network is learned by error back-propagation using the conjugate gradient and coordinate descent minimization of deviation. Learned neural network reconstructs the two-dimensional scalar physical field with distribution having one or two Gaussian peaks.

This paper presents the development of an Internet-based system to allow monitoring of important process variables from a distributedcontrol system (DCS). The system is formulated as an add-on to an undergraduate experiment on the development of a desktop DCS. This paper describes the hardware and software design considerations which facilitate the users to access the process variables on the DCS, remotely and effectively, using only a commonly available Web browser.

distributed, real time sensor networks are essential for effective surveillance in the digitized battlefield and for environmentalmonitoring. We present the first systematic theory that leads to novel sensor deployment strategies for effective surveillance and target location. We represent the sensor field as a grid (two- or three-dimensional) of points (coordinates), and use the term target at a grid point at any instant in time. We use the framework of unidentified codes to determine sensor placement for unique target location. We provide coding-theoretic-bounds on the number of sensors and present methods for determining their placement in the sensor field. We also show that sensor placement for single targets provides asymptotically complete (unambiguous) location of multiple targets.

This paper presents the estimation of travel time on highways based on macroscopic modelling. The focus is on real-time values as compared to average or static values. The macroscopic models are used for distributed and time/space lumped settings and corresponding travel time estimation functions and algorithms are developed. The implications of these algorithms for the implementation of various incident management and traffic control strategies are also discussed.

This paper describes the architecture and the foundations of a telegeomatic system designed for monitoring road traffic pollution and the transportation of hazardous materials in the city of Mohammedia, Morocco, in real-time. The telegeomatic system consists of an integration of a spatial decision support system with new information and communication technologies in a reactive context. With regard to the decision aspect, the fuzzy modelling and, in particular, the fuzzy routing techniques are also described in this paper. Some orientations are also discussed for the integration of real-time intelligent system capabilities.

This paper describes the design and development of DEVS/GDDM, an environmental platform for data distribution management, that allows us to study the interestbased quantization scheme in order to achieve effective reduction of data communication in distributed simulation. After a brief review of interest-based quantization scheme, we discuss the implementation of this scheme as a layer above the DEVS/HLA modeling and simulation environment. This paper presents theoretical analysis for bandwidth utilization of the interest-based quantization scheme, especially with predictive and multiplexing extensions, and empirical results in ballistic missiles simulation executing on the DEVS/GDDM environment in NT networking platforms. The results indicate that the DEVS/GDDM environment is very effective and scalable due to reduced local computation demands and extremely favorable communication data reduction with a reasonably small potential for error.

While there has been a significant amount of research on technical issues regarding the development of agent-based learning environments, there is less information regarding cognitive requirements for these environments. The management of control is a prime issue with agent-based computer environments given the relative independence and autonomy of the agent from other system components. The author discusses four dimensions of control that should be considered in designing agent-based learning environments. The first dimension of control involves instantiating the instructional purpose of the environment on a constructivist (high learner control) to instructivist (high program/agent control) continuum. The second dimension entails managing feedback, and several issues need to be considered: type, timing, amount, explicitness, and learner control of agent feedback. Third, agent vs learner control is further defined through the desired relationship of the learner to agent(s) (e.g., agent as learning companion, agent as mentor, multiple pedagogical agents, agent as personal assistant, or agent as resource). Fourth, to be instructionally effective, the agent(s) must assert enough control so that the learner develops confidence in the agent(s) in terms of believability, competence, and trust. Overall, an array of possible permutations of system versus learner control must be carefully considered.

The coordinated exploitation of modem communication, micro-sensor and computer technologies makes it possible to give global reach to our senses. Web-cameras for vision, web-microphones for hearing and web-"noses" for smelling, plus the abilities to sense many factors we cannot ordinarily perceive, are either available or will be soon. Applications include (a) determination of weather and environmental conditions on dense grids or over large areas, (b) monitoring of energy usage in buildings, (c) sensing the condition of hardware in electrical power distribution and information systems, (d) improving process control and other manufacturing, (e) development of intelligent terrestrial, marine, aeronautical and space transportation systems, (f) managing the continuum of routine security monitoring, diverse crises and military actions, and (g) medicine, notably the monitoring of the physiology and living conditions of individuals. Some of the emerging capabilities, such as the ability to measure remotely the conditions inside of people in real time, raise interesting social concerns centered on privacy issues. Methods for sensor data fusion and designs for human-computer interfaces are both crucial for the full realization of the potential of pervasive sensing. computer-generated virtual reality, augmented with real-time sensor data, should be an effective means for presenting information from distributed sensors.
