The article “Mechanistic-Empirical Design of Bituminous Roads: An Indian Perspective” (A. Das and B. Pandey, Journal of Transportation Engineering, 1999:463–471) presents an equation of the form y = a(1/x1)b(1/x2)c for predicting the number of repetitions for laboratory fatigue failure (y) in terms of the tensile strain at the bottom of the bituminous beam (x1) and the resilient modulus (x2). Transform this equation into a linear model, and express the linear model coefficients in terms of a, b, and c.

Let yt = φyt−1 + et with et ∼ WN(0,σ2) and |φ| < 1. Consider the over-differenced process wt = (1 − L)yt.(i) What is the model followed by wt? (ii) Is wt invertible? (iii) Obtain V [wt] and compare its magnitude with V [yt] and hence comment on the impact of over-differencing on the variance of a stationary process.

Solve An article in the ASCE Journal of Energy Engineering (1999, Vol. 125, pp.59-75) describes a study of the thermal inertia properties of autoclaved aerated concrete used as a building material. Five samples of the material were tested in a structure, and the average interior temperatures (°C) reported were as follows: 23.01, 22.22, 22.04, 22.62, and 22.59.
