In the design of solar air heaters (SAHs), channel depth is a principal variable to be fixed.
The principal variable to be fixed in the design of a PV cooling duct is its depth, and hence the hydraulic diameter of its cross-section D. Analysis of the flow and heat transfer in the duct under still-air (buoyant flow) conditions, when the temperature rise is greatest, is validated by measurements on a full-scale test rig.
The study focuses on the response of three principal variables to random, frequency-bounded excitation: the displacement of the mounting location of the discrete spring mass, the relative displacement of the discrete mass to this mounting location, and the absolute displacement of the discrete mass.
The WA Data Linkage Branch adheres to data linkage best practice protocols [ 19] and uses probabilistic matching based on medical record number, surname, first name and initial, date of birth, sex and address as the principal variables to link the data.
The questionnaires were selected from among those most commonly used to evaluate symptoms of fibromyalgia, and the principal variables related to this syndrome.
For the teeth, the principal variables contributing to the second axis are mainly measurement related to the placement of the incisors (LI1MDL, LI2MDL, LI1BLL, UI1MDL and UI1BLL), canines (LCMDL, LCBLL, UCMDL and UCBLL) and the breadths of the lower molars (LM1BL, LM2BLL and LM3BLL) (Table 1).
Using a principal component (PC) variable to represent the average expression of the top 5 ranked genes, a "cluster" of positively and negatively correlated genes predictive of outcome is easily visualized when plotting the p-value of each gene's hazard ratio (HR) against its correlation to this PC.
For each segment, Table 5 provides the mean scores of the three factors in the various groups, the sociodemographic characteristics and the principal variables for access to and use of the outpatient services.
The objective of this study is to determine the baseline risk of the principal variable, consumption of resources in the population of patients who die from malignant neoplasm.
The principal variable is the equivalence ratio, φ, while the swirl number and mean axial entry velocity remain constant.
In this paper, the boundary value problem for the differential-operator equation with principal variable coefficients is studied.
