Fast and accurate measurement of the instantaneous average active power is useful for building Energy Management System (EMS) in order to assure quality of service such as continuity, optimize energy consumption and reduce carbon dioxide emission. In this paper the problems connected to the measurement of the instantaneous average active power for energy usage improving are discussed, also as the operational processes which deal to solve such problems.

A brief description of the designed digital sampling electricity meter based on the modern Texas Instruments TMS320C6711 DSP is given. The electricity meter measures basic electric network parameters such as rms values of voltages and currents, powers, energy, power factor and net frequency. A brief discussion of measurement accuracy and error correction is also given. The designed calibration procedure of the current and parasitic phase shift between the measured voltage and current based on the active power measurement is described.

In the paper modern CAD (computer aided design) techniques will be used for the analysis and design of a 20 kV combined current-voltage instrument transformer (CCVIT). The magnetic phe-nomena in the complex non-linear electromagnetic CCVIT system will be studied by using the finite element method in the three-dimensional domain and the original program package FEM-3D. The magnetic field analysis will derive the exact CCVIT metrological characteristics. The FEM-3D results are basis for further optimal CCVIT design from metrological aspect by using the stochastic method-genetic algorithm...

The paper describes an improved low-cost add-on measurement system for the 3-D analysis of carotid arteries. The system locates in the 3-D space the contours of vessel walls extracted from a series of 2-D acquisitions, thanks to the measurement of the geometrical parameters of the ultrasonic probe positions and orientations. Features of the proposed system include the possibility to realize free-hand measurements, to work with the desired number of images and to process both normal B-mode and Power-angio images. In the paper, the realized prototype will be described and its operation will be...

In this paper we propose a methodology for intelligent analysis of genomic measurements. It is based on a sequential scheme of Support Vector Machines and it can be used for class prediction of multiclass genomic samples. The proposed methodology was evaluated using two lung cancer datasets. The results are comparable and in many cases higher to the accuracy of relevant methodologies that have been proposed in the literature.

The micro machining technology has been advanced on the basis of the semiconductor manufacturing technology. In this study, the research on the manufacturing the integrated micro optical sensor accumulated LD and PD on the semiconductor substrate is practiced. The fabrication method is the technology of photolithography and etching technology in the semiconductor manufacturing. The blood flow meter is taken up as a typical application of the micro optical sensor.

The heart rate and blood pressure power spectrum, especially the power of the low frequency (LF) and high frequency (HF) components, have been widely used in the last decades for quantification of both autonomic function and respiratory activity. Discrete Wavelet Transform (DWT) and the Fast Fourier Transform (FFT) represent important tolls in this field. The paper presents a new solution for LF and HF evaluation that combines the Daubechies DWT with neural processing techniques. Several types of neural networks (Radial Basis Function and Multilayer Perceptron) capable of evaluating LF and...

This paper is the continuation of the experiments with the mobile phone radiation effect on Lemna minor. Here, the effect of 217 Hz modulation with electric field strength of 23 V/m, 2 hours long exposure at the frequency of 900 MHz, was taken into the account. The results showed no statistical growth decrease. A peroxidase activity in exposed plants was slightly increased. Observed changes were small both for growth and peroxidase activity.

In this paper is proposed an algorithm of prediction fuzzy for chaotic time series. This approach has been select because, in presence of specific pathologies, biomedical data may be represented as a chaotic time series. In particular, we are interested in monitoring the intracranial pressure (IP) of some patients in a state of coma who were suffering from intracranial hypertension syndrome. In these particular cases, prediction is necessary (from a diagnostic point of view) if you want to operate at the right moment on IP abnormal conditions. The proposed approach is based on a prediction...

Early detection of melanoma is one of the greatest challenges of dermatologic practice today. A new diagnostic method, the “ELM 7 point checklist”, defines a set of seven features, based on colour and texture parameters, which describe the malignancy of a lesion. It has been presented as faster and with the same accuracy than the traditional ABCD criteria in the diagnosis of melanoma. In this paper a preliminary step to the automated diagnosis of melanocytic skin lesions, based on ELM 7 point checklist, is proposed. In particular, an image processing methodology focussed on finding the...
