In this Public Service Design Seminar (PSDS), we will design and build products with developmentally disabled students at the Protestant Guild Learning Center in Waltham, MA. The class will work closely with community clients to make sure that what is developed is helpful and functional. These products will be built using the Hobby Shop equipment, the water jet machine in particular. Over the course of the seminar, this class will teach students how to use the OMAX® Jet Machining Center commonly called the water jet and associated OMAX® software. The product development process will also be detailed in depth: determining customer needs, concept development, prototyping, design, and manufacturing.

The course material emphasizes mathematical models for predicting distribution and fate of effluents discharged into lakes, reservoirs, rivers, estuaries, and oceans. It also focuses on formulation and structure of models as well as analytical and simple numerical solution techniques. Also discussed are the role of element cycles, such as oxygen, nitrogen, and phosphorus, as water quality indicators; offshore outfalls and diffusion; salinity intrusion in estuaries; and thermal stratification, eutrophication, and sedimentation processes in lakes and reservoirs. This course is a core requirement for the Environmental MEng program.

This subject is concerned with quantitative methods for analyzing large-scale water resource problems. Topics covered include the design and management of facilities for river basin development, flood control, water supply, groundwater remediation, and other activities related to water resources. Simulation models and optimization methods are often used to support analyses of water resource problems. In this subject we will be constructing simulation models with the MATLAB® programming language and solving numerical optimization problems with the GAMS optimization package.

This course will examine current conditions and trends in water and sanitation services in low and middle income countries. Within it we will take a critical look at the underlying political, economic, social, and technical reasons why almost a billion people lack access to improved water supplies and almost 2 billion still do not have improved sanitation services.

Using water as the unifying theme, explore ocean and freshwater topics and instructional strategies to integrate environmental content in your teaching practice.

This course is an introduction to basic ideas of geophysical wave motion in rotating, stratified, and rotating-stratified fluids. Subject begins with general wave concepts of phase and group velocity. It also covers the dynamics and kinematics of gravity waves with a focus on dispersion, energy flux, initial value problems, etc.

This course discusses the Linearized theory of wave phenomena in applied mechanics. Examples are chosen from elasticity, acoustics, geophysics, hydrodynamics and other subjects. The topics include: basic concepts, one dimensional examples, characteristics, dispersion and group velocity, scattering, transmission and reflection, two dimensional reflection and refraction across an interface, mode conversion in elastic waves, diffraction and parabolic approximation, radiation from a line source, surface Rayleigh waves and Love waves in elastic media, waves on the sea surface and internal waves in a stratified fluid, waves in moving media, ship wave pattern, atmospheric lee waves behind an obstacle, and waves through a laminated media.

Wavelets are localized basis functions, good for representing short-time events. The coefficients at each scale are filtered and subsampled to give coefficients at the next scale. This is Mallat's pyramid algorithm for multiresolution, connecting wavelets to filter banks. Wavelets and multiscale algorithms for compression and signal/image processing are developed. Subject is project-based for engineering and scientific applications.

PHYS201x follows introductory physics courses with a more detailed treatment of oscillators, waves on strings, and electromagnetic waves. In addition to deriving and solving the wave equation, mathematical methods will be introduced on making approximations, describing oscillations with complex numbers, and synthesizing functions with Fourier series. Optical reflection and refraction will be derived, as well as the lens equation and elements of geometrical optics. Optical interference, diffraction, and polarization will be covered in detail, including the role of diffraction in image formation. PHYS201x will have weekly video lectures that explain the material through detailed derivations and demonstrations. There will be weekly homework, a discussion forum, and two exams. Eight weeks of content will be presented, and one week devoted to each self-paced exam.

Course 12.307 is an undergraduate course intended to illustrate, by means of 'hands on' projects, the basic dynamical and physical principles that govern the general circulation of the atmosphere and ocean and the day to day sequence of weather events.  The course parallels the content of the new undergraduate textbook Atmosphere, Ocean and Climate Dynamics by John Marshall and R. Alan Plumb.

Learn how to predict the weather professionally, access weather satellites, and decode the latest meteorological reports

In this course you’ll get hands-on experience making web applications accessible. You’ll understand when and why users need accessibility. Then you’ll dive into the “how”: making a page work properly with screen readers, and managing input focus (e.g. the highlight you see when tabbing through a form.) You’ll understand what “semantics” and “semantic markup” mean for web pages and add ARIA markup to enable a range of assistive devices. Finally, you’ll learn styling techniques that help users with partial vision navigate the your pages easily and reliability.

This MOOC provides a free professional development opportunity to help higher educational professionals meet the challenges of addressing accessibility in web based content.

Learn how to build and deploy modern web application architectures – applications that run over the Internet, in the "cloud," using a browser as the user interface.
