An improved switching converter model
… mode has been done by averaging and discrete-sampling techniques. The averaging technique is simple to use and averages the output voltage. The discrete technique is very complex and cumbersome, but accurately predicts the envelope of the output voltage. A new model is developed by …

Orientation dependence of the acoustic backscatter for elongated zooplankton
… to experimental limitations of animal motion, discrete sampling and observed side lobe levels. The backscatter directivity patterns of live decapod shrimp, determined experimentally at frequencies between 72 and 525kHz, are presented. A non-monotonic relationship between beamwidth and frequency …

Water quality modelling of a grossly polluted stream using continuous monitoring.
… monitoring was performed in conjunction with a discrete sampling and analysis programme, which covered eight sites upstream of the WQMS. Continuous flow gauging was also performed, with a stream flowmodel based on unit hydrograph theory being developed for the period prior to flow gauge …

Medium Resolution
… of materials. By the nature of their discrete sampling, however, these representations vary in their precision. What the architect encounters in the 3D modeling software is not the material itself in its infinite specificities, with its weight, moisture content and smell, but rather a …

The kinetics and mechanisms of destabilisation and aggregation of microcolloidal iron and associated phosphate during simulated estuarine mixing
… Acta, 1988, vol 52 pi 123) - all using 'discrete sampling during mixing and Duffy (PhD Thesis, University of Southampton) - using continuous sampling with more rapid mixing. Variations among the 'discrete' methods are small relative to those between them and the method of Duffy (1985) …

Sampling error of the supremum of a Lévy process
… difference of the continuous supremum and discrete maximum of a Lévy process that is often used in finance. We will show that the expected difference is a quantity that highly depends on the variational property of the underlying Lévy process. Two techniques are used with respect to the …

Toward improved assessment of freshwater salinization as a benthic macroinvertebrate stressor
… evapotranspiration dynamics. Alternative discrete sampling intervals can approximate the pattern revealed by continuous SC data if sampling intervals are ≤ 30 days. Continuous SC variables did not significantly improve precision for prediction of benthic macroinvertebrate metrics (p > 0.1) …

An analytic model to predict detection threshold and performance data for misconvergence on a shadow-mask CRT
… the unique features of a color CRT, that is, the discrete sampling imposed by the shadow mask/ phosphor-dot arrangement as well as the electron beam phase relationships. The model also includes a flexible beam profile which allows the user to specify the desired shape of the beam profile, that is, …

Exploring the Spatial Distribution of Marine Nitrogen Fixation Through Statistical Modeling, High-Resolution Observations and Molecular Level Characterization
… with current techniques, which are based on discrete sampling and long incubation time. To overcome some of the drawbacks of traditional methods, our laboratory developed a method for high-frequency underway N2 fixation measurements. This method provides better coverage of the spatial and …

Design of a power profiler for domestic load research analysis
… Energy measurement ICs were used instead of discrete sampling of voltage and current to improve accuracy and allow the use of a low- cost and easy to program digital signal controller for measurement processing and storage. Several communication options were incorporated into the Power …
