EM610 - Computational Methods
Credits: 3
This course will provide a working knowledge of selected computational methods used in engineering problem solving. The course presents the perspective of computational mathematics as a tool - as an ends to a means, not the end in itself. As such, basic theory will be presented, however use as a practical tool in modern engineering analysis and design will be stressed. The course will review classic solution of ordinary and partial differential equations in mechanics and the thermal sciences, with these same solutions accomplished numerically via use of the MATLAB/Simulink mathematics package available from MathWorks. Upon reviewing relatively simple analytical solutions to some common engineering problems, it is expected that the student will have an appreciation for when the computer-generated solutions are “in the ballpark” and when these solutions are incorrect - the so-called “sanity check” that all prudent engineers apply when using computer- generated solutions. The course will be fast-paced, with the information presented at a depth consistent with the course objective and time constraints.

EM670 - Marine Industry Policy
Credits: 3
To understand where the Merchant Marine is today and where it will be in the future, it is necessary to understand its origins and history. From the earliest days of the republic, the United States government has taken an active role in creating the nation maritime policy. From laws dealing with tariffs and tonnage taxes to the modern Maritime Securities Program, the history of the commercial Merchant Marine has been intertwined with that of the government. At times, it has fostered innovation and the development of technologies, at others it has hindered and stymied growth. This course will examine the history of the United States maritime policy and the history of the US Merchant Marine, with a specific interest toward the rise of the Merchant Marine in the early 19th century, the decline of the Merchant Marine following the Civil War, and its attempted resurrection under the Merchant Marine Act of 1936. We will also study how the use of new technologies, globalization, and the growth of commerce in the late twentieth century has created the merchant fleets of today.
