Spectral analysis of Heart Rate Variability (HRV) is used for the assessment of cardiovascular autonomic control. In this study Continuous Wavelet Transform (CWT) has been used to evaluate the effect of local anesthesia on HRV parameters in a group of fourteen patients undergoing axillary brachial plexus block. A new method which takes signal characteristics into account has been presented for the...
The design of a triple-band planar monopole antenna is proposed. This antenna covers IEEE 802.11a, 802.11b, and 802.11g WLAN bands. Since the antenna is printed on a substrate, it can be easily integrated with the associated microstrip circuits lying on the same plane of the substrate. The antenna has been designed by using IE3D, a full wave MoM simulator from Zeland, USA. The characteristics of the...
