In this paper we continue study on the Stepwise Adaptation of Weights (saw) technique. Previous studies on constraint satisfaction and data classification have indicated that saw is a promising technique to boost the performance of evolutionary algorithms. Here we use saw to boost performance of a genetic programming algorithm on simple symbolic regression problems. We measure the performance o...

Surface acoustic wave (SAW) pulscs cvcrc cxcitctl in C60 films on a variety of substratcs using pulscs from Excimcr lasers for cxcitation. An optical beam deflection technique and polymer elcctrct transduccrs tvcrc utilizcd to detect the propagation of the SAW pulsc with high spatial and tcmporal resolution, allowing an accuracy of bcttcr than O.lfl/o for SAW velocity mcasuremcnts. With this te...

Background: An oscillating bone saw is rarely used to perform laminectomy. The purpose of this study was to describea relatively quick and harmless technique for multilevel laminectomy in patients with lumbar spinal stenosis (LSS) usingan oscillating bone saw to find out how this instrument affects the time of surgery and rate of complications.Methods: This prospective study w...

The impact of ambient humidity on a surface acoustic wave (SAW) propagation in the structure consisting of hematoporphyrin (Hp) film deposited on a piezoelectric lithium niobate substrate has been studied. The SAW transmission dependencies on frequency were measured using an RF network analyzer, and the variation in the SAW velocity was measured using SAW delay-line oscillator technique. The in...

The detection of NO2 in ambient air requires sensors that are capable of measuring concentrations in the low ppb range at high resolution. Using a cyclic measuring technique, a resolution below 1 ppb has been attained at concentrations below 10 ppb with a Surface Acoustic Wave (SAW) sensor. This technique requires that the SAW sensor is first put into a defined initial state by a combination of...

Using a seed layer-free hydrothermal method, ZnO nanorods (NRs) were deposited on ST-cut quartz surface acoustic wave (SAW) devices for ammonia sensing at room temperature. For a comparison, a ZnO film layer with a thickness of 30 nm was also coated onto an ST-cut quartz SAW device using a sol-gel and spin-coating technique. The ammonia sensing results showed that the sensitivity, repeatability...
