Alternate title: Closed-Form Back-Calculation of Rigid-Pavement Parameters Using Barycentric Horizontal Distance of Deflection Basin. I used otolith size and fish size at hatching as a common point in biological intercept method of back-calculation. This paper was sponsored by TRB committee AFD80 Standing Committee on Pavement Structural Modeling and Evaluation. Back-calculation methods designed to assess individ- ual growth such as the Fraser-Lee and biological intercept methods have taken this phenomenon into account by using individual growth trajectories (Campana, 1990).The results show that the proposed HD-BACK has the great potential in back-calculation of rigid-pavement parameters, with the lower sensitivity and the lower fitting error to the measured deflection. The sensitivity, robustness and efficiency of the compared three methods are first analyzed using a numerical example, and subsequently, the proposed method is validated with the field measured deflections by FWD as inputs, where the squared errors between the field measured and back-calculated deflections are investigated. Comprehensive comparison is conducted among the presented method and two widely used closed-form back-calculations called ILLI-BACK and NUS-BACK, respectively. Back-calculation, Classication, and Emulation-based Inference for Spatial Infectious Disease Models by Gyanendra Pokharel A Thesis presented to The University of Guelph In partial fullment of requirements for the degree of Doctor of Philosophy in Mathematics and Statistics (Applied Statistics) Guelph, Ontario, Canada c Gyanendra Pokharel. These features might include the time when persons were exposed and the source of the outbreak. The closed-form solution procedure of the HD-BACK is proposed and a corresponding numerical calculation MATLAB program is developed for this purpose. Back-calculation is a process whereby generally unobservable features of an event leading to a disease outbreak can be inferred either in real-time or shortly after the end of the outbreak. The HD-BACK adopted simplified calculations and leads to easy application, in which the deflection information of each sensor of FWD (Falling Weight Deflectometer) is used, and the principle of back-calculation is to minimize the sum of the squared errors of the measured deflection basin.
Figures 7a and b represent the effect of curing time on the back calculated tensile stress-stain response and flexural load-deflection response of type A and B macro synthetic fibers. This paper presents a solution of back-calculation analysis of rigid-pavement parameters using the barycentric horizontal distance of deflection basin, called HD-BACK. Results of back-calculation of stress-strain responses by trilinear tensile model for all mixtures are shown in Table 5.
