Flux-Based Estimation of Field Capacity
Journal of Geotechnical and Geoenvironmental Engineering, 1999Field capacity has been defined as the water content at which the drainage flux from a soil ceases, or becomes negligible. Field capacity is most commonly estimated as the water content at a pressure head of 1/3 bar, which ignores its flux-based nature.

Measurement of Field Capacity with a Neutron Meter
Soil Science Society of America Journal, 1958Abstract An experiment to determine the moisture vs time curve, and hence the field capacity, was carried out at 6‐inch increments to a depth of 5 feet on 4 soils. Plots of soil were soaked with water and a soil moisture meter employing neutron scattering used to determine the moisture content of the soil profile at different times ...

Information Capacity of a Radiation Field
2010Coherence conditions define the volume of a mode and the number of modes in a radiation field. The number of spatial modes or independent channels is equal to the maximum number of pixels in a plane. The field amplitudes of thermal sources fluctuate randomly, and the superposition of different modes produces a fluctuating interference pattern (speckle)

The Krafla Geothermal Field, Iceland: 3. The generating capacity of the field
Water Resources Research, 1984This paper presents analytical and numerical studies of the generating capacity of the Krafla field. A general lumped parameter model is developed which can be used to obtain rough estimates of the generating capacity of a geothermal field based on the size of the wellfield, the average formation porosity, and the amount of recharge to the system.

Field Validation of Collaborative Capacity Audit
2008Abstract : This phase of our study further develops and refines a collaboration capacity survey that was designed by the authors in 2003. Using verbal protocols with subject-matter experts in the DoD acquisition arena, field-testing, and a literature review, the researchers piloted alternative forms of the diagnostic survey.

Development of an anaerobic capacity test for field sport athletes
Journal of Science and Medicine in Sport, 2003Maximally accumulated oxygen deficit (MAOD) has been argued to be currently the best non-invasive method for estimating anaerobic capacity (Medbø et al., 1988, Ramsbottom et al., 1997). An easy to administer field test that could accurately predict MAOD, would be of great use to many field sport athletes and coaches.

Refining the Definition of Field Capacity in the Literature
Journal of Irrigation and Drainage Engineering, 1998The normalized water content calculated with the simple algebraic equation θ\df\dc = (\Iq\N\df\dc/K\ds)¹/\un, where \iq\df\dc = 0.5 mm/day and \iK\i\ds = hydraulic conductivity, can be used to estimate field capacity. The water content calculated with this relationship is close to the water content at 1/3 bar matric potential for all soils.

Correlation of Field Capacity between Open Field and Laboratory Determinations
1973Since the appearance of the first research works dealing with agricultural soil-hydrology, the empirical concept of field capacity imposed itself as a practical nessicity (Richards and Wedleigh, 1952). The results of later studies have clearly proved the uncertainty of this concept and, consequently, the difficulties in its practical application.

Capacities and Function Spaces on the Local Field
AIP Conference Proceedings, 2006In this article, we will compare non‐linear capacities with Hausdorff measure and present a trace theorem on Besov space over local field. These studies play important roles in existing fractal analysis on the Euclidean space.
