An underground practical sensing system was developed to detect covered-over manholes along the sewer lines under the urban pavement. The sensor head of the system is composed of a sonde and some transmitting and receiving circuits. Coil-type antennas has been designed and implemented base on the induction principle and numerical simulation. The transmitting circuits generate excitation current for the transmitting antennas, and the signal received by the receiving antennas is processed with the receiving circuits. A windows-based application software can calculate phase shift as well as amplitude value of the receiving signal. And there is also a distance-measurement device to provide information about the location of the covered-over or missing manholes. Satisfactory results have been achieved from the field tests of the system in actual manholes. For loop antennas with a spacing of 0.5 m, the system has a phase resolution of about 1/spl deg/ and an amplitude resolution of about 0.5%.

An electroencephalogram that was captured with electrodes placed can easily get contaminated with a variety of artifacts. Here is a comparative of various electroencephalogram (EEG) de-noising techniques. Three alternative techniques are used to eliminate five different kinds of noise, and also the outcomes are evaluated. These three methods are just the Least Mean Square (LMS) technique, the Connected Neural Network, and also the Recursive Least - square (RLS) adaptable algorithm (FCNN). Period charts of the actual EEG signal, the noise EEG signal, and thus the predicted EEG signal are used to display the results. RRMSE and signal- to-noise ratio were utilized to compare the effectiveness of the 3 de-noising strategies in this study. Investigating the model parameters in this case, we discover the FCNN forecasts a better outcome compared to the other two methods.

Cell manufacturing is widely introduced to cope with the dynamically changing market demands. This study considers a scheduling method for a cell assembly system for the products that are characterized by the type and specification. A major set up is required at a cell for the change of types and a minor one for the change of specification within the same types. The scheduling will be made in three folds. Firstly, the scheduling for the orders with due dates of the day is made before the processing of the day starts. If cells have slack times for the production of the orders of the day, express orders to be completed within the day will be accepted in a prespecified time period or until no cells become available for the production. If slack times still exist, advanced production of orders with future due dates will be considered. Auction-based algorithms are proposed for the scheduling and their effectiveness is investigated by simulation studies. © 2008, IFIP International Federation for Information Processing.

To overcome the limitation of the pulse-coupled neural network (PCNN) for its application in processing of color images, the hue data were introduced into the basic PCNN model by adopting the signal generator to control the internal activities of cells. The pixels with the same grey level and different hue data were pulsed separately in the double-input PCNN. It is indicated that the double-input PCNN can achieve the segmentation of color images and is robust to noises. The experimental results on synthetic images and natural images verify the validity of the model.

A district heating grid is a hot water pipeline grid used to transmit waste heat from CHP (Combined Heat and Power) production plants to buildings, where it is used for service water and space heating. Currently, broad use of district heating is limited to Northern Europe and some regions in Central Europe, but the European Union Energy Efficiency Directive 2012/27/EU and Energy Performance of Buildings Directive 2010/31/EU drive the widespread adoption of this technology in member states. Further, these directives push the introduction of significant renewable local energy production into these grids, creating a need for a smart district heating grid that is in many ways analogous to the smart electric grid. One major difference is that in a hot water pipeline grid, there are significant delays in energy propagation, so algorithms developed for the smart electric grid are not directly applicable. In this paper, an auction based heat trade mechanism is proposed between an auctioneer agent representing the CHP plant operator and prosumer agents representing end users with local solar thermal generation capacity. A predictive simulation is used by an auctioneer to account for the said delays in energy production and to determine the market price that best satisfies the performance indicators defined by the CHP plant operator. The proposed multi-agent system is demonstrated by co-simulating it against a model of a part of a Finnish municipality's district heating grid.

Extended TP model transformation for polytopic representation of impedance model with feedback delay

In force controlled industrial robots, haptic and telemanipulation devices stability and control performance are contradicting requirements. In distributed systems where the sensors, actuators and control logic are separated in space, due to the network delays the control process may become unstable. In our research, we consider the coupled impedance type control algorithms as common used method in telemanipulation and interaction control of robots. In this paper, an extended TP model transformation is proposed to convert the delayed system into a polytopic tensor product (TP) model considering the value of the feedback delay as a parameter. Using such model, controller design become tractable as it does not contain feedback delay. A numerical example for a single degree of freedom impedance model with feedback delay is discussed. The results are confirmed by simulation.

Thermal analysis using finite element modeling (FEM) is widely used in automotive industry nowadays. FEM can give simulation results at design stage. However, as FEM is a kind of simulations, it normally suffers from deviations with experimental results. Therefore, experimental measurement is necessary. To measure the 3D temperature distribution on a car body, we normally use a number of temperature sensors and then record the temperature values according to the positions of the sensors. It can provide the temperature values at different positions. Using this information, we can obtain the 3D temperature distribution on a car body. However, this method is time consuming and inconvenient, as we have to place a number of sensors on a car body, measure its corresponding positions as well as process the measured temperature values. In contrast, we firstly take a sequence of 2D thermal infrared images of the car body to have 2D temperature distribution and then reconstruct the 3D temperature distribution from the 2D images using computer vision method. It provides a more convenient method to acquire 3D temperature distribution compared to using a number of temperature sensors. The experimental results show the feasibility of our method.

High computation rates can be achieved using artificial neural networks. Optimization problems can be solved by neural networks with feedback connections by employing a massive number of simple processing elements with high degree of connectivity between these elements. In this paper, an application of Hopfield neural networks in robust parametric estimation with unknown-but-bounded disturbance is presented. The internal parameters of the Hopfield neural network are obtained using the valid-subspace technique. These parameters are explicitly computed to assure the network convergence. A comparative analysis with other robust estimation methods is carried out by a simulation example.

This paper presents the conceptual framework and simulation results on a general technique for time delay compensation in teleoperation, based on the prediction of the human arm position and force, i.e. effectively the master state. This is shown to be significantly less complex and more intuitive than predicting the slave and environment dynamics. Simple polynomial or spline predictors, employing no knowledge of the human arm dynamics, are shown to produce good performance for small time delays when the master force and position are smooth. However, for real life force profiles, better performance is achieved by employing a human arm model and predicting the neural input to it.
