What is fluid-solid interactions ? It is what happens when the motions of a fluid and of a solid are somehow coupled. This happens all the time, around you when leaves flutter in the wind, inside you when your heart beats, above you when wings of a plane vibrate, under the sea... The idea behind this MOOC is to give you the basic tools to be able to predict and eventually mitigate things called flutter, galloping, sloshing, vortex-induced vibrations, added mass, to cite a few. We are going to consider any possible domains of applications such as civil engineering, aerospace engineering, nuclear engineering , ocean engineering, biomechanics and even food processing ! This is why we called the course “Fundamentals of Fluid Solid Interactions ”. There are so many phenomena and so many models that we need to work together on the basic mechanisms . If you want to see how fluid-solid interactions work, and be able to use that knowledge, join us ! A first session of the course was run in early 2016, with learners from over 100 countries. It is now available with subtitles, in English and now in Chinese. See the video at http://goo.gl/YKSMnD

Focusing on the Large Marine Ecosystems (LMEs) of the world, this course will introduce the concept and practice of ecosystem-based management. LMEs occupy areas of coastal ocean at least 200 000 km² or greater in size. These coastal waters produce 12.6 trillion USD in ecosystem goods and services annually and are vitally important for billions of people around the globe. Because LMEs are bounded by ocean features and are globally linked, management of human activities needs to occur in an integrated fashion across political boundaries and economic sectors (e.g. fishing, shipping, energy, tourism, and mining.) This represents a new type of management approached - shifting from single sector-based to multi-sector assessment and management within the spatial domain of the world's 66 Large Marine Ecosystems. There is global high-level support for this new approach and in this course, we will introduce the concepts and tools for assessing and managing LMEs. Together, leaders and experts in a global movement to recover and sustain the goods and services of LMEs will introduce you to the mechanisms used for assessment (Transboundary Diagnostic Analysis), planning and implementation (Strategic Action Programme). Based on recent activities in implementation and practice of the LME approach in 22 projects around the globe, we will showcase examples of effective management at this scale, and highlight the challenges and issues. By the end of the online course, we hope you will be able to actively use this knowledge to advance sustainable development of the world’s oceans. The course was created with the support and input of: the Global Environment Facility (GEF), the United Nations Development Program (UNDP), the National Oceanic and Atmospheric Administration (NOAA), UNESCO-IOC and IW:LEARN.

This course gives you a complete insight into the modern design of digital systems fundamentals from an eminently practical point of view. Unlike other more "classic" digital circuits courses, our interest focuses more on the system than on the electronics that support it. This approach will allow us to lay the foundation for the design of complex digital systems. You will learn a set of design methodologies and will use a set of (educational-oriented) computer-aided-design tools (CAD) that will allow you not only to design small and medium size circuits, but also to access to higher level courses covering so exciting topics as application specific integrated circuits (ASICs) design or computer architecture, to give just two examples. Course topics are complemented with the design of a simple processor, introduced as a transversal example of a complex digital system. This example will let you understand and feel comfortable with some fundamental computer architecture terms as the instruction set, microprograms and microinstructions. After completing this course you will be able to: * Design medium complexity digital systems. * Understand the description of digital systems using high-level languages such as VHDL. * Understand how computers operate at their most basic level (machine language).

What is climate change ? How are mountain regions affected by the evolution of water resources and their uses ? What kind of risks need to be considered ? Mountains are recognized as particularly sensitive physical environments where intense and rapid changes have in the past, and may increasingly in the future, place pressure on their resource base. In this context, a team of roughly 100 experts worked from 2008 to 2013 for the European ACQWA project (www.acqwa.ch) which was coordinated by the University of Geneva. The primary objectives of the project were to assess the impacts of a changing climate on the quantity and quality of water originating in mountain regions, particularly where snow- and ice melt represent a large, sometimes the largest, streamflow component. A further objective of the project was to determine the potential disruptions to water-dependent economic activities related to the climate impacts on hydrological systems, and to propose a portfolio of possible adaptation strategies. This particular MOOC is inspired by the ACQWA Project and offers a better understanding of climate change, its impacts on the quality and quantity of water in mountain regions and the risks related to changing water resources. From an interdisciplinary perspective, the participation of twenty-five instructors from five different countries (Switzerland, England, South Korea, India and Nepal) and fourteen institutions (UNIGE, RTS, UNIFR, UZH, ETHZ, Meteodat GmbH, WGMS, Imperial College London, Agroscope, République et Canton de Genève, Yonsei University, IHCAP, ICIMOD, SDC, FOEN) highlights the diversity of both theoretical and practical viewpoints related to these issues. By the end of this course, you will be able : - to define the general concept of climate change in mountain regions - to understand the concepts associated with climate change such as adaptation and water governance strategies - to consider the impacts of climate change on water resources in mountain regions - to identify the impacts of climate change on hydropower, agriculture, aquatic ecosystems and health - to enumerate risks that can occur in mountain areas and lead to disruptions in water availability and use. Your acquired knowledge will be evaluated through multiple-choice quizzes at the end of each unit of the course. This MOOC on “Climate Change and Water in Mountain Regions : A Global Concern” was initiated and financed by the University of Geneva, through its Institute for Environmental Sciences. We look forward to you joining us !

This course can also be taken for academic credit as ECEA 5361, part of CU Boulder’s Master of Science in Electrical Engineering degree. Hardware Description Languages for Logic Design enables students to design circuits using VHDL and Verilog, the most widespread design methods for FPGA Design. It uses natural learning processes to make learning the languages easy. Simple first examples are presented, then language rules and syntax, followed by more complex examples, and then finally use of test bench simulations to verify correctness of the designs. Lecture presentations are reinforced by many programming example problems so that skill in the languages is obtained. After completing this course, each student will have fundamental proficiency in both languages, and more importantly enough knowledge to continue learning and gaining expertise in Verilog and VHDL on their own.

Integrated landscape management and large-scale landscape restoration should be in every company’s business strategy because in order to reach the Sustainable Development Goal on Land Degradation Neutrality (SDG Number 15.3) scaling up and acceleration of business-driven landscape restoration is urgently needed. This requires business professionals with a vision, the right knowledge and skills. This MOOC aims to train the next generation of business professionals and developers to acknowledge business’ interdependency with healthy landscapes and understand the value of ecosystem resources. “Historically, we have found countless ways to justify our continued exploitation of the environment: discovery, tradition, Manifest Destiny, even Chinese hoax. But we’re all out of excuses now. Each passing day swells the data on greenhouse gases and extreme weather, shrinking reservoirs and rising sea levels, and diminishing biodiversity. Our resources are finite, the window for change if not firmly shut, is certainly closing, and all life must adapt or be doomed.” Téa Obreht, The New Yorker, Dec. 19&26, 2016, p. 106. It is a frightening prospect indeed – that all life on Earth must either adapt or be doomed. This course is about landscape degradation – a global and wicked problem that is contributing to the dooming prospect of depletion of Earth’s finite resources. But this course is also about the solutions to this problem – business driven landscape restoration. So rather than leaving you powerless with the prospect Obreht puts fowards above, it is our hope that you learn how you can be part of the solution to making sure that Planet Earth still provides a safe and habitable home for future generations. We must act big and we must act now. With this course we want to pass on valuable knowledge and teach you useful skills that you can apply in your professional life that will enable you to tackle the issue of landscape degradation and restoration. The issue is urgent, so let’s dive right into it. This MOOC is developed by the ENABLE partnership, which is co-funded by the ERASMUS+ programme of the European Commission and involves a diverse, international group of organizations including Rotterdam School of Management, Erasmus University, Commonland, United Nations University Land Restoration Training Programme, the Spanish National Research Council and Estoril Global Conferences.

Digital Signal Processing is the branch of engineering that, in the space of just a few decades, has enabled unprecedented levels of interpersonal communication and of on-demand entertainment. By reworking the principles of electronics, telecommunication and computer science into a unifying paradigm, DSP is a the heart of the digital revolution that brought us CDs, DVDs, MP3 players, mobile phones and countless other devices. The goal, for students of this course, will be to learn the fundamentals of Digital Signal Processing from the ground up. Starting from the basic definition of a discrete-time signal, we will work our way through Fourier analysis, filter design, sampling, interpolation and quantization to build a DSP toolset complete enough to analyze a practical communication system in detail. Hands-on examples and demonstration will be routinely used to close the gap between theory and practice. To make the best of this class, it is recommended that you are proficient in basic calculus and linear algebra; several programming examples will be provided in the form of Python notebooks but you can use your favorite programming language to test the algorithms described in the course.
