Lung sound analysis is made difficult by the inevitable noise contamination. Conventional frequency filtering is usually ineffective, therefore the use of other methods like those based on the wavelet transform is needed. In this paper, we propose a new technique for denoising lung sound This technique is based on Donoho's method and consists in modulating the wavelet packet coefficients before the thresholding operation and demodulating them after. By using this method, we can reduce the noise without distortion of the original sound. The results obtained with normal and pathological sounds show a very high efficiency.

This paper reports on: (i) a review of published research on the neurophysiological effects of EMF; and, (ii) experiments carried out to determine whether a 50 Hz Electric and Magnetic Field (EMF) similar to those associated with electric power transmission lines or appliance use affect the human brain function. The literature review indicated that only very few research results have been reported. The authors' experiments measured the human brain reaction time and mental rotation under the EMF and sham exposure. No statistically significant differences were observed due to field status.

Electromagnetic field therapy is a non invasive method for the treatment in the physical therapy and rehabilitation. Biomagnetic Micro Massage Therapy (BMMT), is a new therapeutic method, which is achieved by using specially designed apparatus. Clinical application of BMMT shows improved and accelerated healing in several groups of illnesses. This is accomplished by interaction of Pulsing Electro Magnetic Fields (PEMF), and static fields of Magnetic Pillows (MP).

Describes an energy approach to the acupuncture phenomenon based on the bioenergetics of the cells in the body surface receptor "acupoints" following the signal transduction postulate in a biomolecular model. Using the gamma camera scintillation technique "Acupuncture Scintigraphy" with technetium pertechnetate, various minimal dose injection (25-200 micro Ci) intra-acupoints were gamma visualised with different connections instead of the well known blood, lymphatic or nerve pathways. Over 3 years in human volunteers and animal laboratory research, acupoints scintigraphy has been applied to basic scientific investigation: biophysics and biomolecular studies have been used to profile the meridians system.

A new skin impedance imaging device enabled us to monitor the Skin Electro-bioimpedance Relief (SER) processes such as initial autowaves and induced wave-like dynamics. The SER's response to a remote non-thermal mm-EMF input was investigated in the skin "bioactive" zone (MC7; 20/spl times/40 mm) of healthy subjects and subjects suffering from vegetal-vascular dysfunction. No significant changes were seen in healthy subjects. In unhealthy subjects, in response to switching on of the mm-EMF, a speed of the dominating coherent structure (CS) increased sharply from fractions of mm/min to about 5-7 mm/min; suppression of the neighbouring CS was also observed. In response to switching off of the mm-EMF input, a reverse jump (5-7 mm/min) of the dominating CS back front and reemergence of the neighbouring CS was seen.

The effect of a commercial magnetic water conditioner on the viscosity of a range of aqueous solutions was investigated. In order to measure low viscosities a simple, rolling ball viscometer was constructed. Flight time of the ball was determined by optical sensors and the viscosity computed directly. Significant differences in viscosity were observed in all the magnetically treated solutions except the ion-free milliQ water.

This paper contains a brief outline of the engineering requirements for a cochlear implant speech processor based on wavelet techniques. Signal processing in cochlear implants typically involves filtering and noise removal, spectral estimation (to the frequency response of the hearing-impaired individual) and equalisation across desired frequencies. These various signal processing functions are typically implemented using separate hardware and microprocessor stages. In contrast, wavelet analysis inherently supports feature extraction, ambient noise removal and spectral estimation through the use of selected frequency-localised functions. Appropriate basis selection can incorporate noise, spectrum and equalisation (scaling) considerations. Thus it is possible to integrate the various signal processing requirements into a single DSP-based (digital signal processor) solution.

A model is presented for the local flow of electric current, based on the known electrical properties of the tissues which comprise the human head. It is applied to the design of an instrument for the direct non-invasive measurement of the skull's impedance, addressing the need for exceedingly high impedances at frequencies in the 10 to 100 kHz range. It is shown how the design achieves impedances in excess of those of the usually achieved with operational amplifiers, even when their open loop gains are strictly limited. The performance characteristics of a hardware realisation of the design are presented.
