Analysis of generic single-pole, two-pole, and three-pole operational transconductance amplifiers (OTAs) is carried out based on settling time. The most important design metrics the open-loop frequency response, such as stability margins gain-bandwidth product (GBW) are related to time single-, two- three-stage OTAs in closed-loop configuration, enabling present a procedure for each OTA specifi...

To evaluate the influence of episodic events on particle and hydrophobic organic contaminant (HOC) cycling in the Great Lakes, we deployed sequencing sediment traps at two locations in the western arm of Grand Traverse Bay, Lake Michigan. The traps collected integrated samples of settling particles every 2 weeks from May 1997 to September 1999. The total polycyclic aromatic hydrocarbon (t-PAH) ...

The aerobic granular sludge process is a promising technology for the removal of nutrients and organic contaminants from wastewater. However, a large amount of the sludge is often washed out during the start-up of granular reactors, which results in reduced process performance and a protracted start-up phase. In this study, the possibility of a rapid start-up of the nitrification process throug...

the results of batch settling tests (bst) are used to investigate settling behavior of solids suspension, which contribute to sizing thickeners. conventional methods in analyzing bst on the basis of visual and graphical procedures lead to sub-optimally sized and selected thickeners. a computational approach based on quantitative analysis of bst can be beneficial. about 300 settling experiments ...

In this paper, a simple design method of proportional-integral (PI) controllers is proposed for higher order (HO)-plus delay time (HOPDT) processes. This controller is designed to handle higher order processes with long dead times, long time constants, and monotonic or oscillatory responses. The method is based on the real and imaginary values of the higher order processes for the desired settl...
