This is the textbook of a graduate course given in 2024 at the University of Twente on "Scientific computing with open-source software".
This subject is a seminar-style course aimed at anyone who is interested in founding a software company or working for a software company or company that uses software technology extensively as a senior manager, developer, or product/program manager. It is also appropriate for people interested in the industry or in working as an industry analyst. Many of the issues we discuss are highly relevant for companies whose businesses are heavily dependent on software, such as in e-business or financial services, or embedded software for industrial applications.
This course provides you with a framework to understand the structure and dynamics of high-tech businesses, together with an approach for their effective strategic management. It is focused on domains in which systems are important, because either or both products are parts of larger and more complex systems, or they are comprised of systems. The domains covered include computing, communications (in particular the mobile and IP domains), consumer electronics, industrial networking, automotive, aerospace and medical devices. The course will be of particular interest to those interested in managing a business in which technology will likely play a major role, and also to those interested in investing in or providing counsel to these businesses.
The emphasis throughout is on the development and application of ways of thinking or mental models that bring clarity to the complex co-evolution of technological innovation, the demand opportunity, systems architecture, business ecosystems, and decision-making and execution within the business.
This lesson focuses on ultrasound wavelengths and how sound frequencies are used by engineers to help with detection of specific distances to or in materials. Students gain an understanding about how ultrasonic waves are reflected and refracted. Students also see how ultrasound technology is used in medical devices. The activity following this lesson allows students to test their knowledge by using the Sunfounder Ultrasonic sensor and Arduino Mega Microcontroller.
