Answer to Problem 1QAP

The brief description of two stages involved in the formation of particles of a new phase is explained below.

Explanation of Solution

The two stages involved in the formation of particles of a new phase are:

  • Nucleation
  • Growth

Nucleation:

The development of very miniature nuclei of a new phase from the parent phase, similar to embryo is known as nucleation. There are two types of nucleation, heterogeneous and homogeneous nucleation.

In heterogeneous nucleation, nuclei produce at non-homogeneous structures, like surface of container, boundaries of grain and so on.

In homogeneous nucleation, nuclei or particles produce within parent phase.

Growth:

The growing phase of the particle is called as growth. In this phase, the particles transform into a stable nucleus and the size of embryo got bigger than the decisive shape. The process of growth forms a new phase nuclei within the parent phase. The process of growing continues till the new formed nuclei got stable and replace the parent nuclei.

Laboratory Preliminary Discussion First-order Low-pass RC Filter Analysis The first-order low-pass RC filter shown in figure 1 below represents all voltages and currents in the time domain. It is of course possible to solve for all circuit voltages using time domain differential equation techniques, but it is more efficient to convert the circuit to its s-domain equivalent as shown in figure 2 and apply Laplace transform techniques. vs(t) i₁(t) + R₁ ww V₁(t) 12(t) Lic(t) Vout(t) = V2(t) R₂ Vc(t) C Vc(t) VR2(t) = V2(t) + Vs(s) Figure 1: A first-order low-pass RC filter represented in the time domain.

A.15 Consider a communication channel, transfer characteristic of which is defined by the nonlinear relation, y(t) = x(t) + x² (t), where x(t) is the input and y(t) is the output. Assuming the input is an FM signal, x(t) = cos (2лft+(t)), find y(t). Is it possible to retrieve x(t) from y(t)? If so, how?
Question 2 A nickel-titanium alloy is used to make components for jet turbine aircraft engines. Cracking is a potentially serious problem in the final part because it can lead to nonrecoverable failure. A test is run at the parts producer to determine the effect of four factors on cracks. The four factors are: pouring temperature (A), titanium content (B), heat treatment method (C), amount of grain refiner used (D). Two replicates of a 24 design are run, and the length of crack (in mm x10-2) induced in a sample coupon subjected to a standard test is measured. The data are shown in Table 2. 1 (a) Estimate the factor effects. Which factor effects appear to be large? (b) Conduct an analysis of variance. Do any of the factors affect cracking? Use a = 0.05. (c) Write down a regression model that can be used to predict crack length as a function of the significant main effects and interactions you have identified in part (b). (d) Analyze the residuals from this experiment. (e) Is there an…
