Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Harmonics mitigation of industrial power system using harmonic blocking compensators

, 2014
This paper presents a passive harmonic blocking compensator (PHBC) for harmonic suppression and reactive power compensation in distribution systems. PHBC composed of a line series filter tuned to the fundamental frequency and a shunt passive filter. FORTRAN Feasible Sequential Quadratic Programming (FFSQP) is used as an optimization tool to find the ...

Foreign labor, peer‐networking and agricultural efficiency in the Italian dairy sector

Agribusiness, EarlyView.
Abstract While the presence of immigrants in the agricultural sector is widely acknowledged, the empirical evidence on its economic consequences is lacking, especially from a microeconomic perspective. Using the Farm Accountancy Data Network panel data for Italian dairy farms in the period 2008–2018, the present study investigates the relationship ...

Machine-side Harmonic Suppression Strategy for Direct Driven Five-phase PMSG of Wind Power Generation System

Advances in Electrical and Computer Engineering
Wind power generation system with five-phase PMSG contains a large amount of third harmonic in the stator phase current of the machine side due to the dead-time effect of the converter and non-sinusoidal air-gap magnetic field.

Deep Learning‐Assisted Coherent Raman Scattering Microscopy

Advanced Intelligent Discovery, EarlyView.
The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...
