The dual slope integrating analog to digital converter (ADC) is an efficient one for wireless transmission of ECG signals. Normally the dual slope ADCs are used for high resolution applications and the accuracy is very high. The main advantage of the ADC design is its high speed with low power. The dual slope ADC consists of integrator, comparator and a ten bit binary counter. To design integra...

This study creates a landfill design application in a server that can be accessed by engineers via the World Wide Web. Through this system, engineers can complete a side slope design and/or landfill evaluation. Instead of using traditional engineering computation techniques to analyze a problem, this study presents a new method that uses a database to analyze landfill slope stability problems. ...

The present paper analyzes radio signal propagation in long tunnels with different cross sectional size and shape at various signal carrier frequencies, transmitter/receiver positions and material properties applying computer simulations. The influences of different parameters were investigated and results were compared to the empirical four-slope path loss model for long tunnels. It was shown ...

Significant three-dimensional ~3-D! environmental variability exists in the vicinity of the shelf break along the mid-Atlantic Bight. This study examines the influence of azimuthal coupling due to this variability on acoustic propagation in this region. Numerical studies employing a 3-D ray code, a hybrid ray-mode code, and a 3-D parabolic equation model are used to study the significance of az...

BACKGROUND Few studies have examined the impact of the built environment configuration upon mental health. The study examines the impact of objectively assessed land use and street network configuration upon psychological distress and whether this association is moderated by the natural environment and area-level deprivation. METHODS In a community sample of 687 older men from the Caerphilly ...

LS is a very important factor in erosion evaluation. Slope gradient and slope length is used to calculate LS factor. However a major limitation is the difficulty in extracting the LS factor at regional landscape scales. The geographic information systembased (GIS-based) methods which have been developed for estimating the slope length for USLE and RUSLE model also have limitations. he unit cont...

BACKGROUND Fluctuating asymmetry is a contentious indicator of stress in populations of animals and plants. Nevertheless, it is a measure of developmental noise, typically obtained by measuring asymmetry across an individual organism's left-right axis of symmetry. These individual, signed asymmetries are symmetrically distributed around a mean of zero. Fluctuating asymmetry, however, has rarely...
