The potential of the SAGE (Space Alternating Generalized Expectation Maximization) algorithm for navigation systems in order to distinguish the line-of-sight signal (LOSS) is to be considered. The SAGE algorithm is a low-complexity generalization of the EM (Expectation-Maximization) algorithm, which iteratively approximates the maximum likelihood estimator (MLE) and has been successfully applie...

Various types of impinging jet flows are analytically modeled using inviscid free Gaussian jet solutions superimposed with experimentally fitted boundary layer models. Improved (more robust) and simplified solutions to existing models are defined. Velocity profiles, surface pressure distributions, and streamline plots are calculated for circular, plane, and annular impinging jets. The models sh...

Headwater species and peripheral populations that occupy habitat at the edge of a species range may hold an increased conservation value to managers due to their potential to maximize intraspecies diversity and species' adaptive capabilities in the context of rapid environmental change. The southern Appalachian Mountains are the southern extent of the geographic range of native Salvelinus fonti...

A moving metallic plate subject to heating and cooling boundary conditions is considered in this work. The plate is heated by an imposed heat  ux, and cooled down by an array of impinging jets through convection and radiation. The objective of the present work is determination of operating conditions for controlling the temperature distribution at the end of both heating and cooling sections. ...

CAUSES AND FUNCTIONAL CONSEQUENCES OF DENITRIFYING BACTERIA COMMUNITY STRUCTURE IN STREAMS AFFECTED TO VARYING DEGREES BY WATERSHED URBANIZATION by

Some new efforts based on chemical-looping system for capturing and converting CO2 into methanol are discussed in this study. In chemical-looping technology, an oxygen carrier has to be transported between circulating fluidized beds, which require additional energy and processes, like cyclone and seals. This may be one of the main drawbacks at high operating temperatures. In a new reactor conce...

BACKGROUND A promising route to renewable liquid fuels and chemicals is the fermentation of synthesis gas (syngas) streams to synthesize desired products such as ethanol and 2,3-butanediol. While commercial development of syngas fermentation technology is underway, an unmet need is the development of integrated metabolic and transport models for industrially relevant syngas bubble column reacto...

The combined SHARON-Anammox process for treating wastewater streams with high ammonia load is the focus of this paper. In particular, partial nitritation in the SHARON reactor should be performed to such an extent that a nitrite:ammonium ratio is generated which is optimal for full conversion in an Anammox process. In the simulation studies performed in this contribution, the nitrite:ammonium r...

In this paper an overview on the use of membrane reactors to immobilise micro-organisms in a stirred tank reactor during continuous heavy metal biosorption tests is presented. Experimental data were collected in different operation conditions of pH and biomass concentration both with single and binary metal solutions in membrane reactor apparatus using Sphaerotilus natans as biosorbent. A dynam...

• Triple impinging jet mixer can be used for mixing unequal streams. Acetylsalicylic acid flow reaction mixture was separated and purified effectively. Small crystal size unimodal distribution were achieved. Temperature antisolvent to solution ratio have a significant effect on yield. This study aims develop continuous crystallization technique using novel non-submerged triple multiple feeding ...
