For hands-on experience on applying the numerical methods, MATLAB or Python programming will be used for homework assignments and the final project. The knowledge you obtain throughout this course will make you more confident in applying numerical methods to deal with complex mathematical problems you may encounter in your career.

Explore the essential principles of Naval Architecture and Marine Engineering in this course, designed to bridge theory and practice. Through a combination of lectures, hands-on assignments, and a comprehensive practicum project, students will delve into key topics such as vessel geometry, structural and hydrostatic analyses, dynamic stability, and propulsion systems. Emphasizing practical application, the course integrates systems architecture principles, including trade studies and adherence to design requirements. This course is for engineers interested in maritime projects or advancing their studies in Naval Architecture. Proficiency in CAD/FEA design tools and MATLAB is recommended.

Acoustical Oceanography will cover how active and passive use of sound can be used to study physical parameters and processes, as well as biological species and behaviors, in the ocean environment. The first half of the course will focus on the underlying physics of sound propagation, generation, reception, and scattering in the ocean environment. This foundation will then be leveraged and expanded upon to explore applications of acoustical oceanography for physical, geological, and biological insight through both direct and inverse methods. Throughout the course current research topics will be presented including acoustic tomography, geologic bottom inversion, and marine mammal characterization.

An introduction to the required theoretical and practical background in the design and development of haptic applications. Haptic technology enables users to touch and/or manipulate virtual or remote objects in simulated environments or tele-operation systems. This course aims to cover the basics of haptics through lectures, assignments, and readings on current topics in haptics. Prerequisite(s): Recommended course background: graduate and senior undergraduate students who are enthusiastic to learn about haptics and basic familiarity with MATLAB.

An individually tailored, supervised project on a subject related to mechanical engineering. The content and expectations are formalized in negotiations between the student and the faculty sponsor. This course may only be taken in the second half of a student’s master degree program. All independent studies must be supervised by a current ME instructor (exceptions must be approved by the Mechanical Engineering Program Chair) and must rely on material from prior ME courses. The independent study project proposal form (see https://ep.jhu.edu/current-students/student-forms/) must be approved prior to registration.

This course provides masters students in mechanical engineering the opportunity to conduct original research for a thesis under the guidance of a faculty advisor. Students will identify a research topic, review relevant literature, develop research questions and/or hypotheses, design a study methodology, collect and analyze data, and interpret findings. The culmination of the course is a scholarly project report suitable for publication that demonstrates the student's mastery of mechanical engineering research methods and their ability to advance knowledge in the field. The research must be conducted at the level of at least a master’s degree, as determined by the student’s research advisor, which can be an academic advisor, a current full-time faculty member at the Department of Mechanical Engineering at Johns Hopkins University, a research staff member at the Johns Hopkins University Applied Physics Laboratory, or an active instructor affiliated with one of the Engineering for Professionals programs. Prior written approval of the advisor and the program chair must be received before enrolling in this course. The thesis approval form (see https://ep.jhu.edu/current-students/student-forms/) must be approved prior to registration.

This course provides guidance and support for mechanical engineering masters students writing their final thesis. Students will review relevant literature, refine their research questions/hypotheses, analyze data, draw conclusions based on their research, and work with feedback from peers and faculty advisors to improve their writing. The primary focus of the course is the production of the master’s thesis, including ensuring necessary components like an introduction, literature review, methodology, results, and discussion sections are present. Students will develop scholarly writing and editing skills so that their thesis is publication-ready by the end of the course, demonstrating their ability to conduct and clearly convey independent research in mechanical engineering. Students interested in this course must have prior approval from their advisor and the Program Chair to follow the Thesis track. The thesis approval form (see https://ep.jhu.edu/current-students/student-forms/) must be approved prior to registration.
