Aerobic, anoxic, and anaerobic selectors have become popular for controlling filamentous bulking in activated sludge systems; however, selectors are not always successful. Regression analyses of data collected from 48 full-scale wastewater treatment plants, with operating selectors, provided a method for ranking the importance of selector operating and design parameters (with respect to their i...

A chiral ionic liquid (IL), S-[3-(chloro-2-hydroxypropyl)trimethylammonium] [bis((trifluoromethyl)sulfonyl)amide] (S-[CHTA](+)[Tf(2)N](-)), which can be easily and readily synthesized in a one-step process from commercially available reagents, can be successfully used both as co-electrolyte and as a chiral selector for CE. A variety of pharmaceutical products including atenolol, propranolol, wa...

In this paper, we present an image stabilization algorithm based on Nikon’s Best Shot Selector [11]. We implement Best Shot Selector and use super resolution concept to reconstruct blurred images. Image stabilization includes optical and digital methods. Optical stabilization applies gyroscopic sensors and corrective lens to compensate camera shake optically. Digital stabilization applies image...

The Dantzig selector is a near ideal estimator for recovery of sparse signals from linear measurements in the presence of noise. It is a convex optimization problem which can be recast into a linear program (LP) for real data, and solved using some LP solver. In this paper we present an alternative approach to solve the Dantzig selector which we call “Primal Dual pursuit” or “PD pursuit”. It is...

Timing Selector In article number 2100072, Mingyi Rao, Zhongrui Wang, J. Joshua Yang, and co-workers conceptualize demonstrate a timing selector, which can utilize its nonlinear relation between switching time voltage, instead of current voltage in traditional selectors, to block sneaking memristive crossbar arrays. The operation principles are formulated together with experimental demos using ...
