Impulse Impedance and Effective Area of Grounding Grids
IEEE Transactions on Power Delivery, 2020High values and uneven distribution of the transient ground potential rise (TGPR) at grounding grid conductors in cases of lightning can disrupt the system safety and reliability.

Large mask area effects in selective area growth
Journal of Crystal Growth, 2006In this paper we analyze for the first time selective area growth (SAG) of GaAs by MOVPE on dark field patterns, where the different masking features are dense and at the same time the openings are surrounded by very large mask area (larger than the openings) in all directions.

The foveal color-match-area effect
Vision Research, 1994Rayleigh matches for foveal, temporally alternating fields showed only a small increase in the log green/red matching ratio (0.03--average of 10 observers) as the field was decreased from 116 to 19 min arc. This is consistent with only a small, 10%, change in photopigment density or lengthening of the cone outer segments in the central fovea.

Wealth Effects in the Euro Area
SSRN Electronic Journal, 2018How sizable is the wealth effect on consumption in euro area countries? To address this question, we use newly available harmonized euro area wealth data and the methodology in Carroll et al. (2011b). We find that the marginal propensity to consume out of total wealth averaged across the largest euro area economies is around 3 cents per euro, with a ...

Effective Enforcement in a Conservation Area
Science, 2006Wildlife within protected areas is under increasing threat from bushmeat and illegal trophy trades, and many argue that enforcement within protected areas is not sufficient to protect wildlife. We examined 50 years of records from Serengeti National Park in Tanzania and calculated the history of illegal harvest and enforcement by park authorities.

Effective Area Limit for Large Mode Area Laser Fibers
OFC/NFOEC 2008 - 2008 Conference on Optical Fiber Communication/National Fiber Optic Engineers Conference, 2008We analyze practical constraints of fibers designs for achieving large mode area and single mode operation for fiber lasers, and provide estimated upper limits for the core diameter and effective area.

Realizing Large Effective Area Fibers
Optical Fiber Communication Conference, 2012Performances of state-of-the-art large-A eff single-core fibers are presented. We explain how trench-assisted step-index structures allow to reach A eff up to 160μm2 with 125μm glass diameter. Extension to larger A eff is also discussed.

Effective area method for calculating global properties of cellular materials
Materials Today Communications, 2018Currently, in the literature there does not appear to be any universally adopted cross sectional area calculation used for determining the global mechanical properties of cellular and truss materials.
