It is a call to consider... More > the foundational principles behind those concepts. It is not designed to present novel insights into MBSE so much as to provide a guided tour of the touchstones of systems design. It is a guide to the new MBSE acolyte and a reminder to the experienced practitioner. It is our hope that you find this primer valuable. We welcome your comments and suggestions about improving it. Much of what we have learned about how it should be organized and presented has come from thoughtful contributions from the readers of the 1st edition.< Less
The founder of a small aviation engineering company is daunted by the challenge of raising the funds for an endeavor he knows can be technically successful. He is confronted with resistance from... More > Boeing, the FAA, NASA, the trade press, even local communities as he strives to develop an acoustic hush kit for the Boeing 707. The investors are intimidated and sales are impeded by competing designs even though the success of those programs is highly unlikely. This is a story about how important trust is in business relationships, the large role that luck plays, and even how the litigation industry and tax structure can contribute or destroy a business venture. The successful completion of this program generated hundreds of millions of dollars in revenue, and produced more hush kitted airplanes around the world than all the competitors combined. This is a true story written by the founder.< Less

These notes are based on lectures given by the first author to students in the course on elementary differential equations over many years, and have been
extensively class tested. They can be used as... More > a stand alone text or as supplement to a standard text. Our aim
is to make the subject more interesting by avoiding the usual labor intensive methods in favor of more powerful and elegant methods such as the well known operator methods, rarely described in standard texts. Another example is the use of Leibniz's theorem in power series
solutions. We include many applications and plenty of exercises.< Less
