This set of three videos illustrates how math is used in satellite data analysis. The videos feature NASA senior climate scientist Claire Parkinson. Parkinson explains how the Arctic and Antarctic sea ice covers are measured from satellite data and how math is used to determine trends in the data. In the first video, she leads viewers from satellite data collection through obtaining a time series of monthly average sea ice extents for November 1978 – December 2012, for the Arctic and Antarctic. In the second video, she begins with the time series from the first video, removes the seasonal cycle by calculating yearly averages, and proceeds to calculate the slopes of the lines to get trends in the data, revealing decreasing sea ice coverage in the Arctic and increasing sea ice coverage in the Antarctic. In the third video, she uses a more advanced technique to remove the seasonal cycle and shows that the trends are close to the same, whichever method is used. She emphasizes the power of math and that the techniques shown for satellite sea ice data can also be applied to a wide range of data sets.

Do you want to start or grow your own business, go international, or avoid bankruptcy?

In this business and management course, you will learn the key steps to take to design or innovate your own business model. You will learn about the trade-offs to be made, and the design issues that are critical for a viable and sustainable business model.

This course will help you answer questions like, how do I create a simple business model in a structured way, how do I engage my users and how do I create value for my customers as well as revenue for my company.

The Hubble Space Telescope has provided us with remarkable insights into our universe, but its start was anything but smooth.

This course is designed to provide both undergraduate and graduate students with a fundamental understanding of human factors that must be taken into account in the design and engineering of complex aviation and space systems. The primary focus is the derivation of human engineering design criteria from sensory, motor, and cognitive sources to include principles of displays, controls and ergonomics, manual control, the nature of human error, basic experimental design, and human-computer interaction in supervisory control settings. Undergraduate students will demonstrate proficiency through aviation accident case presentations, quizzes, homework assignments, and hands-on projects. Graduate students will complete all the undergraduate assignments; however, they are expected to complete a research-oriented project with a final written report and an oral presentation.

This course analyzes seminal work directed at the development of a computational understanding of human intelligence, such as work on learning, language, vision, event representation, commonsense reasoning, self reflection, story understanding, and analogy. It reviews visionary ideas of Turing, Minsky, and other influential thinkers and examines the implications of work on brain scanning, developmental psychology, and cognitive psychology. There is an emphasis on discussion and analysis of original papers; students taking the graduate version complete additional exercises and a substantial term project.

HydroViz is an educational "virtual" hydrologic observatory developed for a "real" watershed and is based on integration of field data, remote sensing observations and computer simulations of hydrologic variables and processes. The main purpose of HydroViz is to support hydrology education in engineering and earth science courses.

This course covers the development of the fundamental equations of fluid mechanics and their simplifications for several areas of marine hydrodynamics and the application of these principles to the solution of engineering problems. Topics include the principles of conservation of mass, momentum and energy, lift and drag forces, laminar and turbulent flows, dimensional analysis, added mass, and linear surface waves, including wave velocities, propagation phenomena, and descriptions of real sea waves. Wave forces on structures are treated in the context of design and basic seakeeping analysis of ships and offshore platforms. Geophysical fluid dynamics will also be addressed including distributions of salinity, temperature, and density; heat balance in the ocean; major ocean circulations and geostrophic flows; and the influence of wind stress. Experimental projects conducted in ocean engineering laboratories illustrating concepts taught in class, including ship resistance and model testing, lift and drag forces on submerged bodies, and vehicle propulsion.

Is Hyperloop really worth the hype? Is this passenger pod levitating in a vacuum tube a viable alternative to curb the environmental impact of current modes of transport?

This revolutionary and more sustainable mode of transportation for passengers or freight can reach speeds of over 1000 kilometers per hour (600mph), decreasing travel time significantly. For example, one could go from Amsterdam to Paris in 30 minutes instead of 4 hours, or from New York to Washington in 25 minutes instead of 3 hours.

Have you ever wondered how levitation works? How would passengers feel? What will infrastructure costs be? Is the Hyperloop concept technically and commercially viable?

Regardless of your background, this course will teach you how this technology works and will prove why it is worth investing in. Key topics include the core concepts behind Hyperloop, current developments in the technology, the future solutions Hyperloop will offer and the problems it faces.

Through discussions with fellow participants and critical thinking you will form your own vision and develop your own ideas about this exciting new technology and its future.

This course is for anyone interested in the Hyperloop concept. For those seeking more in-depth knowledge, or wanting to pursue a career or conduct research in this field, the course provides additional resources.

This course has been designed by the Delft Hyperloop Dream Team, winners of the SpaceX Hyperloop Pod Competition in 2017 and runners up in 2018. This award-winning team consists of TU Delft students, international experts and partner companies who will also share their expertise.

Beim Hörsaal-Spiel "Rot gegen Grün" beantworten die Studierenden Fragen, wobei zwei Gruppen gegeneinander spielen und versuchen, möglichst viele Fragen richtig zu beantworten und somit möglichst viele Punkte zu erreichen. Mit einer solchen Aktion kann der Stoff spielerisch wiederholt und aufgefrischt werden. Außerdem werden der Zusammenhalt und die Gemeinschaft unter den Lernenden gefördert.Der Fragenkatalog enthält etwa 70 Fragen zur den Grundlagen der Elektrotechnik (Gleichstromtechnik und Netzwerkberechnung). Bei Interesse am LaTeX-Quelltext des Dokumentes sowie an den ausführlichen Musterlösungen (nur für Hochschulen) wenden Sie sich bitte an Mathias Magdowski.

The ratio of a sinusoidal voltage to a sinusoidal current is called "impedance". This is a generalization of Ohm's Law for resistors. We derive the impedance of a resistor, inductor, and capacitor. The inductor and capacitor impedance includes a term for frequency, so the impedance of these components depends on frequency. Created by Willy McAllister.

Impedance of 2 elements in series is a complex number. Impedance terminology: reactance, susceptance, admittance. Created by Willy McAllister.

The impedance of capacitors and inductors in a circuit depend on the frequency of the electric signal. The impedance of an inductor is directly proportional to frequency, while the impedance of a capacitor is inversely proportional to frequency. Created by Willy McAllister.

We look at the inductor i-v equations in derivative and integral form. Created by Willy McAllister.

We notice how important it is to give inductor current a place to flow. Created by Willy McAllister.
