Hypertension is a complex syndrome comprised of many systemic abnormalities and life-threatening complications. The importance of factors other than blood pressure is underscored by numerous studies and by the lack of physician interest in blood pressure measurement. We therefore investigated the possibility of detecting hypertension without any reference to blood pressure measurement. Preliminary results suggest that such detection is technically possible and medically necessary

The paper deals with a FFT based measurement procedure which has been implemented in a software module for wide bandwidth digital scopes. The software module can be installed with the purpose of enhancing the scope performance in the frequency domain measurements, in terms of amplitude and frequency uncertainty. The implemented measurement algorithms and uncertainty auto-evaluation procedure are described in detail. Finally, some experimental results are reported with the aim of showing both performance and output format of the signal analysis

In this paper, a novel approach is presented to the measurement of velocity and mass flow rate of pneumatically conveyed fine particles using electrostatic sensing and neural network techniques. A single ring-shaped electrostatic sensor is used to obtain a signal from which the two crucial parameters, velocity and mass flow rate of particles, may be derived for the purpose of monitoring and control. It is found that the quantified characteristics of the signal are related to the velocity and mass flow rate of particles. The relationships between the signal characteristics and the two measurands are established through the use of a back-propagation (BP) neural network. Results obtained on a laboratory test rig suggest that an electrostatic sensor in conjunction with a trained neural network may provide a simple, practical solution to the long standing industrial measurement problem

Multisensor monitoring devices that use skin surface or implanted sensors are susceptible to changes in temperature, sweat, and movement, such that the measured data cannot be used. This paper presents an automatic approach to detect such erroneous sensors. It is based on the assumption that valid measurements are related by a reconstruction model, while measurements from erroneous sensors are unrelated. The method estimates the data at each sensor based on the measurements from all other sensors, and compares it to the measurements. The sensor-data match is tested using ANOVA to detect the presence of an erroneous sensor. The method was tested on simulated and experimental data of electrical impedance tomography (EFT) and showed consistent identification of erroneous electrodes

This paper examines microphone-array-based, combined beamformer-noise canceller structures. The performance of the structures is evaluated using computer simulation as well as experimental measurements. The inter-operation of the beamformer and noise canceller is studied by measuring the SNR improvements offered by the respective components. An experimental procedure for evaluating output SNR is presented: the desired signal is captured from a set location in the recording environment. The noise signal is measured from a second (generally different) location. Results reveal an SNR improvement of up to 17 dB, and are compared to those stemming from conventional approaches

This paper investigates the effects of temporal clipping, which can result from voice activity detection (VAD), or echo canceller's nonlinear processor (NLP), on speech quality. Mean opinion score (MOS) is used as an index of speech quality. A nonintrusive algorithm, based on the clipping locations, is proposed to predict the speech quality. The algorithm shows excellent performance, the correlation coefficient between the prediction and the measurement is about 0.975, and the root mean square error for the prediction is 0.18 MOS

The Edge of Lighttrade is a patented technique of the Institute for Aerospace Research, National Research Council Canada. One application of interest is the inspection of aircraft lap joints for pillowing deformation caused by hidden corrosion. This rapid enhanced visual inspection technique provides an intuitive result, which is a representation of surface topography. In this study, the quantification of the surface deformation is investigated by using a laser displacement sensor as a calibration tool. A procedure that implements the reconstruction of 3D surface from Edge of Light scanning is proposed. Experimental results obtained from a bump simulator are presented

In order to further enhance the hyperspectral image compression, a new scheme based on JPEG2000 and nonlinear correlation measurement is proposed, in which nonlinear correlation coefficient (NCC) is used to guarantee the relationship between every source image and its compressed image is the same. Using the method, all the source images will be compressed in such a way that each compressed image just maintains enough information which can satisfy the post- processing, while achieving the maximum compression ratio

Capacitive RF MEMS switches present several drawbacks such as high actuation voltages, slow switching times and time-varying performances, due to the deterioration of both their mechanical and electrical properties. Such characteristics justify the interest of the scientific community on the development of accurate measurement techniques to monitor the dynamic behavior of capacitive MEMS switches during continuous actuations. In this paper, a novel measurement system devoted to the time-domain characterization of capacitive MEMS switches is proposed. Moreover, an electrical model for such devices is introduced and its lumped elements are characterized by means of measurement results. The proposed test-bench allows to measure the modulus and the phase of both the incident and the reflected signals of a one-port transmission line based, where the port is represented by the capacitive MEMS device. The paper introduces a software tool based on LabVIEWtrade to compute the capacitance and the resistance values of the model as functions of time. In particular the tool transforms the measured signals in the frequency domain to compute the reflection coefficient by means of components depending on the fundamental frequency of the RF signal, thus neglecting spurious frequency components, out-band noise and harmonics due to interferences
