Syllabus for Engineering Statistics • Probability: rules, cond. probability, independence • Summarising and presenting data • Discrete and continuous random variables: probability distributions. Special cases: binomial, Poisson, hypergeometric, normal, exponential • Expected values and variances of r.v.’s, linear combinations • Sampling distributions: sample mean, proportions, variance. Standard error, Central limit theorem • Point and interval estimation: mean, proportion • Control charts: construction and use, Xbar and S
Further topics • Bivariate and multivariate relationships: prediction, modelling, regression etc. • Time series analysis • Reliability of components and systems • Design and analysis of surveys • Design and analysis of experiments • Signal processing: speech, image, video
Microphotograph of a thin section. The colours of different grains are produced due to Birefringence(Double refraction).
To fit ellipses to grains a clear idea about grain boundary is necessary.
Strain Measurement • Magnitude of deformation is a marker of strain. • Hence to measure strain we have to measure ellipse parameters, namely Major and Minor Axes and orientation. • Ellipse parameters are obtained by fitting ellipses to grains.
