The system allows to monitor a wide area in an urban environment, and to analyze measurements so that potential 'critical' locations can be singles out like those where the measured data overcome fixed warning levels, so that suitable corrective actions can be taken. The main advantage of the proposed system is the capability to monitor the spatial and temporal evolution of electromagnetic field over a larger area than using fixed probes. Moreover the architecture allows to collect data from different clients and to send them to a remote server for analysis purposes, which in turn leads to the evaluation of possible correlations that are useful to the process study. The measurement system also provides the integration of data with information like population density: the aggregated information qualifies the results, when areas with different population densities are put in comparison. Eventually, interpretation of acquired data is performed by an innovative fuzzy decision-making procedure, using suitable decision rules in order to minimize risks and costs according to metrological and statistical features of measurement system.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

The sensor system is composed of an inertial measurement unit (IMU) mounted on the foot instep and a biaxial accelerometer mounted on the waist. The IMU integrates a biaxial accelerometer and a rate gyroscope. Both the foot gyroscope and the waist accelerometer are capable to accurately estimate the cadence. Strapdown integration applied to the inertial data allows to reconstruct the trajectory in the sagittal plane of the sensed anatomical point on the foot, yielding the opportunity to determine the desired walking features. Double-integration of the waist accelerometer signals to determine the trunk vertical displacement and root mean square analysis of the waist acceleration modulus allow to construct two predictors of the walking speed, which integrate the information gathered from the inertial estimator. In this paper, preliminary results concerning the accuracy of level walking speed prediction by different methods are presented.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

The circuits use a timing discriminator based on a high-pass CR-filter at the input of the receiver to produce a bipolar pulse from a unipolar one. This pulse has a zero-crossing point that is amplitude independent and thus a wide dynamic range can be achieved by detecting it. Two different structures for the front-end have been presented. The simulated bandwidths and transimpedances are 370 MHz, 280 MHz and 3.4 M/spl Omega/, 5 M/spl Omega/.

Many image fusion methods have been developed in a number of applications. This paper mainly discusses the structures of image fusion process, which is classified as hierarchical fusion structure, overall fusion structure, and arbitrary fusion structure. And the effects of such image fusion structures on the performances of image fusion are analyzed. In the experiment, a typical hyperspectral image data set is fused using the same wavelet transform based image fusion technique, but applying different fusion structures. The differences among their fused images are analyzed. The experimental results testify the theoretical analysis that the performances of image fusion techniques are related not only to the fusion algorithm, but also to the fusion structures, and different image fusion structures that produces different fusion performance even using the same image fusion method.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

Broken liners cause unexpected downtimes affecting the availability, safety and operational costs. In addition, excessive steel and energy consumption cause loss of grinding efficiency and worsen the production expenses. This paper presents a new method based on digital signal processing of acoustical signals collected by a sensor array around a tumbling mill for detecting the level of the harmful impacts within the mill. The impact level allows the improvement of operational control of variables - like the speed- for optimizing the load movement in the mill, reducing, the harmful impacts within the mill. Experimental results at an actual industrial installation are presented.","PeriodicalId":386903,"journal":{"name":"Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat.

It is suitable for the measurement of small capacitive values and very small capacitance variations, and therefore it finds potential application in the capacitive characterization of novel material dielectric properties and in sensors exploiting such properties. In the proposed circuit, we make use of a particular configuration of current-to-voltage converter and of an impedance converter, which is adopted to compensate for the standing capacitance value of the sensor, and then to achieve high sensitivity to small capacitance variations. The presented topology is also suitable for the use in differential approaches where a dummy sensor is adopted to filter out unwanted interfering and modifying signals.
