A Parameterization of Bowen Ratio with Respect to Soil Moisture Availability
The Bowen ratio (B) is impacted by 5 environmental elements: soil moisture availabillity, m, the ratio of resistr ances between atmosphere and soil pores,~, atmospheric relative humidity, h, atmospheric stability, 6.T, and envirD ronment temperature. These impacts have been investigated over diverse surfaces, including bare soil, free water surface, and vegetation covered land, using an analyti...
متن کاملMoisture sorption characteristics of heat treated flour, culinary flour and high ratio cake
The quality of preserved food is largely dependent on its moisture content, moisture migration and/or moisture uptake of the food during storage. Therefore, the water activity level, which corresponds to a range of equilibrium moisture contents, must be determined by, for example, the use of moisture isotherms. The shape of the isotherm curve is dependent on the interactions between the vapour ...
متن کاملAdvanced Thermal-Moisture Analogy Scheme for Anisothermal Moisture Diffusion Problem
We propose an advanced thermal-moisture analogy scheme to cope with the inherent limitations of the existing analogy schemes. The new scheme is based on the experimentally observed unique hygroscopic behavior of polymeric materials used in microelectronics; i.e., the saturated concentration is only a function of relative humidity regardless of temperature. A new analogy formulation based on the...
متن کاملSpatial soil moisture scaling structure during Soil Moisture Experiment 2005
Soil moisture state and variability control many hydrological and ecological processes as well as exchanges of energy and water between the land surface and the atmosphere. However, its state and variability are poorly understood at spatial scales larger than the fields (i.e. 1 km2) as well as the ability to extrapolate field scale to larger spatial scales. This study investigates soil moisture...
متن کاملRatio Ratio
In this paper we describe block algorithms for the reduction of a real symmetric matrix to tridiagonal form and for the reduction of a general real matrix to either bidiagonal or Hessenberg form using Householder transformations. The approach is to aggregate the transformations and to apply them in a blocked fashion, thus achieving algorithms that are rich in matrix-matrix operations. These red...
