Remote controlled partial discharge acquisition unit [PDF]
, 2003 Online partial discharge (PD) analysis for underground high voltage cables has major advantages over the offline techniques. Online techniques usually involve PD data acquisition, storage and post-processing of the data.

Muon-Induced Background Study for Underground Laboratories
, 2005 We provide a comprehensive study of the cosmic-ray muon flux and induced activity as a function of overburden along with a convenient parameterization of the salient fluxes and differential distributions for a suite of underground laboratories ranging in

PPO‐Based Reinforcement Learning for the Semi‐Active Vibration Control of MDOF Platform
AI &Innovation, EarlyView.ABSTRACT Aiming at the coupled vibration problem of a multi‐degree‐of‐freedom (MDOF) vibration isolation platform under eccentric excitation, this paper proposes a semi‐active vibration control strategy based on Proximal Policy Optimization (PPO) ‐based reinforcement learning (PPO RL).

The dimension of the underground economy, in Romania, in the period after 1989 [PDF]
In the period after 1989, the underground economy in Romania had a constantly ascendant evolution. In this article we think about the distinguishness of the underground economy level and of the real possibilities of Romanian economy through the dimension

American Journal of Agricultural Economics, EarlyView.Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

A mobile detector for measurements of the atmospheric muon flux in underground sites
, 2011 Muons comprise an important contribution of the natural radiation dose in air (approx. 30 nSv/h of a total dose rate of 65-130 nSv/h), as well as in underground sites even when the flux and relative contribution are significantly reduced. The flux of the

American Journal of Botany, EarlyView.Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

The size of the underground economy in Japan [PDF]
This paper empirically analyzes the size of the underground economy in Japan. The results show that (i) the size of the underground GDP peaked in the early 1990s but has been declining since; (ii) the underground economy reached its peak in around 1992 ...

A leaf phenomics approach for estimating belowground traits in North American licorice
American Journal of Botany, EarlyView.Abstract Premise Selective breeding over thousands of years has prioritized aboveground yield, with little regard for changes belowground. Roots underpin plant growth and resilience, but our knowledge of these critical structures lags behind that of aboveground structures.

American Journal of Industrial Medicine, EarlyView.ABSTRACT Background Mining workers are exposed to a range of respiratory hazards, including respirable dust. While exposure to respirable crystalline silica in the mining industry has been found to be common, less is known about trends in measured levels of exposure to respirable dust overall.
