Probability and statistics provide an excellent tool for understanding, modeling and communicating uncertainty in engineering systems. In many applications there is the added challenge of considering random quantities that vary over time and/or space. Examples can be found in seismic applications, financial markets, heterogeneous materials, and image processing, among many others. This course provides an introduction into some of the ways in which random processes and random fields are measured, quantified and communicated. Through video lectures, activities, and interactive content, students will learn about correlation functions, spectral density functions, local average processes and Monte Carlo simulation. There will be an emphasis on understanding each concept, estimating these quantities from data, and using this data as the basis for generating realistic sample random processes.

By the end of this course, you will be able to: - Explain the meaning of the correlation function, the spectral density function, homogeneity, ergodicity. - Identify parameters of a random process based on available data. - Relate random process descriptors to reliability via maximum value distributions. - Simulate a random process with desired correlation and/or spectral density function.

In this module, you will be introduced to some basic definitions of random processes and examples of engineering applications in which they are important. There will also be a review of probability density functions to introduce the marginal distribution that describes a random process.

In this module, you will be introduced to the correlation function and correlation length as a means to describe random processes. You will learn to recognize how changes in the correlation function affect the random process, and vice versa. Finally, there will be a case study in which the correlation function & length are calculated based on a given set of data.

In this module, you will be introduced to the spectral density function as an alternative means to describe random processes. You will learn to recognize how changes in the spectral density function affect the random process, and vice versa. Finally, there will be a case study in which the spectral density function & moments are calculated based on a given set of data.

Frequently asked questions

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
