This course aims to give students the tools and training to recognize convex optimization problems that arise in scientific and engineering applications, presenting the basic theory, and concentrating on modeling aspects and results that are useful in applications. Topics include convex sets, convex functions, optimization problems, least-squares, linear and quadratic programs, semidefinite programming, optimality conditions, and duality theory. Applications to signal processing, control, machine learning, finance, digital and analog circuit design, computational geometry, statistics, and mechanical engineering are presented. Students complete hands-on exercises using high-level numerical software.

An experienced professional guides you through a structured approach to database design and development.

This course covers database design and the use of database management systems for applications.

Learn about Databases, one of the most prevalent technologies underlying internet and computing applications today.

This course is designed for website developers who have an interest in incorporating accessible design features into their pages. Web accessibility benefits everyone - those with and those without disabilities, through increased usability and interoperability of web based materials. This class is structured to allow learners to explore the area of web accessibility using a hand-on, project-based approach, with an emphasis on learning by doing, and sharing information and experience with your class mates through online discussions. Students enrolled in this course will be expected to review assigned readings, apply what they have learned through coding projects and participate in class discussions. Evaluation will be based on weekly assignments consisting of 1 or 2 small projects together with review questions, and 1 final project tying it all together. The required course textbook, Web Accessibility: Web Standards and Regulatory Compliance, has been authored by leading authorities in the field and covers such topics as What is Web Accessibility?; Assistive Technology; 508 Guidelines; Emerging Technology; and Using CSS to separate content from presentation. To round out our exploration of web accessibility some online sources will also be consulted.

DNS is an integral part of working with the Internet, but what if you don't understand how it works? This course will give you all the insight you need to have a basic understanding of DNS and how it translates http://74.125.224.72/ into http://google.com/! The class is designed for web professionals and almost anyone looking for a walkthrough on general DNS concepts. We will begin with an introduction to the Domain naming system then move on to how the client computers translate DNS information. Lastly, we will look at the major components of a DNS server and clear up how to work with DNS zones and subdomains.

Dreamweaver has become one of the industry's leading Web site design editing and management tool. This course is designed for students who wish to evaluate the Dreamweaver Web design tool or who would like to learn to use it. The emphasis is on learning to use Dreamweaver as a tool to create a Web site, rather than on learning the basic concepts of Web design and we move very quickly. However, all questions about basic Web design concepts will be answered.

Drupal is a free and open source Content Management System written in PHP. With Drupal you can create a simple personal homepage, a company website, a blog, an ecommerce site, etc. Hundreds of modules are available for use with Drupal. You can create slide shows, events calendars, a contact form, product catalogs, polls or surveys, guestbook, a forum or blog, or newsletter signup. The possibilities are endless. Basically, there are no limits with Drupal, you really can make any type of website you want.

This course is an introductory subject in the field of electric power systems and electrical to mechanical energy conversion. Electric power has become increasingly important as a way of transmitting and transforming energy in industrial, military and transportation uses. Electric power systems are also at the heart of alternative energy systems, including wind and solar electric, geothermal and small scale hydroelectric generation.

This course provides an integrated introduction to electrical engineering and computer science, taught using substantial laboratory experiments with mobile robots. Our primary goal is for you to learn to appreciate and use the fundamental design principles of modularity and abstraction in a variety of contexts from electrical engineering and computer science.

Our second goal is to show you that making mathematical models of real systems can help in the design and analysis of those systems. Finally, we have the more typical goals of teaching exciting and important basic material from electrical engineering and computer science, including modern software engineering, linear systems analysis, electronic circuits, and decision-making.

Course Format

This course has been designed for independent study. It includes all of the materials you will need to understand the concepts covered in this subject. The materials in this course include:

• Lecture videos from Spring 2011, taught by Prof. Dennis Freeman
• Recitation videos, developed for OCW Scholar by teaching assistant Kendra Pugh
• Course notes
• Software and design labs
• Homework assignments and additional exercises
• Nano-quizzes and exams with solutions

Content Development

The course is designed to provide a practical - hands on - introduction to electronics with a focus on measurement and signals. The prerequisites are courses in differential equations, as well as electricity and magnetism. No prior experience with electronics is necessary. The course will integrate demonstrations and laboratory examples with lectures on the foundations. Throughout the course we will use modern "virtual instruments" as test-beds for understanding electronics. The aim of the course is to provide students with the practical knowledge necessary to work in a modern science or engineering setting.
