Bacterial extracellular polymeric substances: Impact on soil microbial community composition and their potential role in heavy metal-contaminated soil

Ecotoxicology and Environmental Safety, 2022
In this study, six different treatments involving extracellular polymeric substances (EPS) from Enterobacter sp. FM-1 (FM-1) (no EPS (control), original bacterial cells (FM-1), FM-1 cells with EPS artificially removed (EPS-free cells, EPS-R), different ...

Topological energy transfer in an optomechanical system with exceptional points

, 2016
Topological operations have the merit of achieving certain goals without requiring accurate control over local operational details. To date, topological operations have been used to control geometric phases, and have been proposed as a means for ...

Optimal scheduler for energy consumption reduction in multi-vector energy management systems: A case study at the Port of Borg

Heliyon
The objective of microgrid operation is to supply the energy demanded by the loads at minimum cost. To achieve this goal, new tools are being proposed in the literature, such as the use of optimal schedulers in the field of multi-vector management ...

The effects of exopolysaccharides and exopolysaccharide-producing Lactobacillus on the intestinal microbiome of zebrafish (Danio rerio)

BMC Microbiology, 2020
Background Numerous studies have reported the health-promoting effects of exopolysaccharides (EPSs) in in vitro models; however, a functional evaluation of EPSs will provide additional knowledge of EPS-microbe interactions by in vivo intestinal microbial

Design of Control Strategies For EPS System

International Journal Of Mechanical Engineering And Information Technology, 2016
Electric Power Steering (EPS) system is an advanced steering system that assists steering torque using the electric motor. In this paper studies have been done on the electric power steering system for a front wheelsteered driven four wheels vehicle. First, the principle and structure of EPS are discussed.

Understanding Anomalous Transport in Intermittent Maps: From Continuous Time Random Walks to Fractals [PDF]

, 2004
We show that the generalized diffusion coefficient of a subdiffusive intermittent map is a fractal function of control parameters. A modified continuous time random walk theory yields its coarse functional form and correctly describes a dynamical phase ...

Improving power system damping using EP based PI controller [PDF]

2011 5th International Power Engineering and Optimization Conference, 2011
This paper presents a new stochastic optimization technique for tuning conventional PI controller parameters of a static var compensator (SVC) which controls a synchronous machine. As a type of Flexible AC Transmission Systems (FACTS) device, SVC is designed and implemented to improve the damping of a synchronous generator.

Multiparticle entanglement with quantum logic networks: Application to cold trapped ions [PDF]

, 2001
We show how to construct a multi-qubit control gate on a quantum register of an arbitrary size N. This gate performs a single-qubit operation on a specific qubit conditioned by the state of other N-1 qubits.

Cascade Backstepping Control With Augmented Observer for Lateral Control of Vehicle

IEEE Access, 2021
This paper proposes a cascaded backstepping control method with an augmented observer for the lateral control of an autonomous vehicle. The proposed cascaded backstepping control structure consists of an inner-loop electric power steering (EPS) system ...
