A novel tri-band T-junction impedance-transforming power divider with independent power division ratios. [PDF]

open access: yesPLoS ONE, 2017
In this paper, a novel L network (LN) is presented, which is composed of a frequency-selected section (FSS) and a middle stub (MS). Based on the proposed LN, a tri-band T-junction power divider (TTPD) with impedance transformation and independent power ...

Steady-state voltage-control method considering large-scale wind-power transmission using half-wavelength transmission lines

open access: yesGlobal Energy Interconnection, 2021
Half-wavelength transmission can transmit large-scale renewable energy over very long distances. This paper proposes an improved steady-state voltage-control method for half-wavelength transmission systems considering large- scale wind-power transmission.

Excitation power-independent photoluminescence of inverted quantum hut structures embedded in SiGe superlattice [PDF]

open access: yesApplied Physics A, 2015
Optical properties of semiconductor nanostructures can be quite different from the bulk semiconductors. We present here results of a photoluminescence study of MBE-grown SiGe superlattice structures having inverted quantum huts of Ge formed below Ge-on-Si interfaces.

Co-Movement Analysis of Italian and Greek Electricity Market Wholesale Prices by Using a Wavelet Approach

open access: yesEnergies, 2015
We study the co-evolution of the dynamics or co-movement of two electricity markets, the Italian and Greek, by studying the dynamics of their wholesale day-ahead prices, simultaneously in the time-frequency domain.

Generating power and controversy: Understanding Tanzania’s independent power projects

open access: yesJournal of Energy in Southern Africa, 2017
Initially conceived of within the broader context of power sector reform in the late 1980s and early 1990s, Independent Power Projects (IPPs) were intended to relieve state utilities of the burden of financing new plants, bring quick, quality power and ...

Power-independent wavelength determination by hot carrier collection in metal-insulator-metal devices [PDF]

open access: yesNature Communications, 2013
Wavelength separation and detection is generally performed by spatial dispersal of incident light onto separate detectors, or by appropriate wavelength-selective filters. Here we demonstrate direct wavelength determination of monochromatic light in a power-independent fashion with a single metal-insulator-metal device.
