Eigenvalue analyses of two parallel lines using a single real transformation matrix
For a typical non-symmetrical system with two parallel three phase transmission lines, modal transformation is applied using some examples of single real transformation matrices. These examples are applied searching an ...
Plastic deformation mechanisms of biomedical Co–Cr–Mo alloy single crystals with hexagonal close-packed structure
This is the first report of the successful fabrication of Co–Cr–Mo biomedical alloy single crystals with a hexagonal close-packed (hcp) structure and the resultant clarification of its deformation behavior. The (0001)〈112¯0〉 ...
Robust control of a single-phase VSI with LCL filter for grid-tie and islanded operation modes applied to PV distributed generation in microgrids environment
This paper introduces a methodology to model and control a single-phase inverter with LCL filter intended for low power PV distributed generation in microgrid scenario. The system should operate in grid connected and island ...
The Effect of the Presence and Presentation Mode of Co-Initiators on the Microtensile Bond Strength of Dual-Cured Adhesive Systems Used in Indirect Restorations

Localized modes in linear and nonlinear octagonal-diamond lattices with two flat bands
(Amer Physical Soc, 2020)
We consider a two-dimensional octagonal-diamond network with a fine-tuned diagonal coupling inside the diamond-shaped unit cell. Its linear spectrum exhibits coexistence of two dispersive bands (DBs) and two flat bands ...
Distributed generation modelling for unbalanced three-phase power flow calculations in smart grids
Distributed Generators (DG) are generally modeled as PQ or PV buses in power flow studies. But in order to integrate DG units into the distribution systems and control the reactive power injection it is necessary to know ...

Control of a supercapacitor energy storage system for microgrid applications
(Institute of Electrical and Electronics Engineers, 2013-05)
The proper operation of a microgrid requires storage devices that increase the inertia and avoid instability of the system. This paper presents the control of an energy storage system (ESS) based on supercapacitors in the ...
