Estimation of cutting forces in micromilling from the signals of a spindle with Active Magnetic Bearings (AMB) is treated as an input estimation problem. For the closed-loop AMB system, a minimum mean square error input estimator with an adjustable delay is derived. This filter is based on the Wiener filter, where the unknown input is treated as white noise filtered by known dynamics and the co...

This paper proposes a closed-loop and implements some metaheuristic optimization approaches to regulate an unstable active magnetic bearing (AMB) system. First of all, hardware model AMB is fabricated in the laboratory. Mathematical analysis carried out linearized open-loop transfer function obtained for equilibrium point operation, using parameters model. Then, closed loop proposed this system...

Amphotericin B (AmB) with deoxycholate (Fungizone) and AmB incorporated into mixed micelles (AmB-mixMs) composed of egg lecithin with glycocholate, deoxycholate, or taurocholate were compared as treatments for murine infections. For mice infected with Candida albicans, treatment consisted of a single intravenous injection; for mice infected with Cryptococcus neoformans, treatment consisted of t...

Conventional active magnetic bearing (AMB) systems use several separate radial and thrust bearings to provide a five-degree of freedom (DOF) levitation control. This article presents novel combination 5-DOF AMB (C5AMB) designed for shaft-less, hub-less, high-strength steel energy storage flywheel (SHFES), which achieves doubled density compared prior technologies. As single device, the C5AMB pr...

This paper proposes a TD (temporal difference) and GA (genetic algorithm)-based reinforcement (TDGAR) learning method and applies it to the control of a real magnetic bearing system. The TDGAR learning scheme is a new hybrid GA, which integrates the TD prediction method and the GA to perform the reinforcement learning task. The TDGAR learning system is composed of two integrated feedforward net...

In this work, a novel application of Active Magnetic Bearing (AMB) is proposed to integrate AMB in the Magnetically Coupled Thruster (MCT) assembly for underwater application. study, 2-Degree-Of-Freedom (DOF) developed and investigated MCT an Unmanned Underwater Vehicle (UUV). The paper presents detailed electro-mechanical modeling in-house system. intractable problem rotor suspension rotation ...

PURPOSE To determine if magnetotactic bacteria can target tumors in mice and provide positive contrast for visualization using magnetic resonance imaging. EXPERIMENTAL DESIGN The ability of the magnetotactic bacterium, Magnetospirillum magneticum AMB-1 (referred to from here as AMB-1), to confer positive magnetic resonance imaging contrast was determined in vitro and in vivo. For the latter s...

G protein-coupled receptors (GPCRs) play a central role in a wide range of biological processes and are prime targets for drug discovery. GPCRs have large hydrophobic domains, and therefore purification of GPCRs from cells is frequently time-consuming and typically results in loss of native conformation. In this work, GPCRs have been successfully assembled into the lipid membrane of nanosized b...
