An approach to compute the polarizability tensor of magnetic nanoparticles having general ellipsoidal shape is presented. We find a surprisingly excellent quantitative agreement between calculated and experimental magneto-optical spectra measured in the polar Kerr configuration from nickel nanodisks of large size (exceeding 100 nm) with circular and elliptical shape. In spite of its approximati...
Magneto-rheological damper (MR damper) has been expected to control the response of civil and building structures in recent years, because of its large force capacity and controllable force characteristics. Recent study is to the application of controllable dampers for reducing earthquake response of buildings and/or wind induced sway. The dynamic characteristics of the MR damper have to be cla...
We continue our investigation of Lithium Lens (LL) for usage in ILC positron conversion system. Magneto-Hydrodynamic and Thermo-dynamic problems discussed in association with ~100 kA feeding pulsed current. Set of Partial Differential Equations used for description of magneto-hydrodynamics phenomena in liquid Lithium flow. Calculations confirm feasibility of liquid Lithium system. Some interest...
This paper describes the dynamic performance of two area interconnected hydro-hydro power systems when subjected to 1% step load perturbation. For this present study, the system is incorporated with conventional Proportional-Integral (PI) controller and Fuzzy Logic Controller (FLC). The dc link is used as system interconnection in parallel with ac tie-lines. The dc link is considered to be oper...
Appropriate modeling of components and related controllers are very significant in studying dynamic performance of power systems. In this paper, an educational procedure for modeling, simulation, and governor tuning of hydro power plants is presented. Different existing dynamic models of hydro plant components are reviewed. The procedure for calculating the required parameters from real plant d...
Iron-peroxide intermediates are central in the reaction cycle of many iron-containing biomolecules. We trapped iron(III)-(hydro)peroxo species in crystals of superoxide reductase (SOR), a nonheme mononuclear iron enzyme that scavenges superoxide radicals. X-ray diffraction data at 1.95 angstrom resolution and Raman spectra recorded in crystallo revealed iron-(hydro)peroxo intermediates with the...
