Inverter voltage control is an important task in the operation of a DC/AC microgrid system. To improve the inverter voltage control dynamics, traditional approaches attempt to measure and feedforward the load current, which, however, needs remote measurement with communications in a microgrid system with distributed loads. In this paper, a load current observer (LCO) based control strategy, whi...

Abstract The politics of knowledge matter to the current wave de-democratization in Europe. Building on Walby’s social complexity theory, this article highlights dynamics between epistemic configurations and contemporary politics. Focusing academic institutions, taking gender studies as an illustration, shows that actors opposing (social) sciences academia not only aim dismantle existing instit...

The primary goals of therapy in the treatment of ulcerative colitis (UC) are to induce remission of patient symptoms as rapidly as possible and maintain remission on a long-term basis. New formulations of mesalazine and corticosteroids show promise in improving compliance and efficacy. There is consistent evidence for the role of cyclosporine in severe UC and expanding evidence for thiopurines ...

This paper describes a uniform transform domain Video Codec where the motion estimation/compensation (ME) is performed in the transform domain. The estimation technique discussed here is a subpixel transform domain ME based on the Dual Tree Complex Wavelet Transform (DT CWT) and a maximum phase correlation technique. The DT CWT is a multiresolution fine-to-coarse bandpass filtered decomposition...

The present study introduces a new approach to determining optimal electrode positions in transcranial direct current stimulation (tDCS). Electric field and 3D conduction current density were analyzed using 3D finite element method (FEM) formulated for a dc conduction problem. The electrode positions for minimal current injection were optimized by changing the Cartesian coordinate system into t...

In recent years, renewable energy sources have been considered the most encouraging resources for grid and off-grid power generation. This paper presents an improved current control strategy for a three-phase photovoltaic grid-connected inverter (GCI) under unbalanced and nonlinear load conditions. It is challenging to suppress the harmonic content in the output current below a pre-set value in...
