Software testing gets a bad rap for being difficult, time-consuming, redundant, and above all – boring. But in fact, it is a proven way to ensure that your software will work flawlessly and can meet release schedules.

In a two-course series, we will teach you automated software testing in an inspiring way. We will show you that testing is not as daunting a task as you might think, and how automated testing will make you a better developer who programs excellent software.

This second course builds upon the first course’s material. It covers more advanced tools and techniques and their applications, now utilizing more than just JUnit. Key topics include Test-Driven Development, state-based and web testing, combinatorial testing, mutation testing, static analysis tools, and property-based testing.

This is a highly practical course. Throughout the lessons, you will test various programs by means of different techniques. By the end, you will be able to choose the best testing strategies for different projects.

This book treats optics at the level of students in the later stage of their bachelor or the beginning of their master. It is assumed that the student is familiar with Maxwell’s equations. Although the book takes account of the fact that optics is part of electromagnetism, special emphasis is put on the usefulness of approximate models of optics, their hierarchy and limits of validity. Approximate models such as geometrical optics and paraxial geometrical optics are treated extensively and applied to image formation by the human eye, the microscope and the telescope.

Polarisation states and how to manipulate them are studied using Jones vectors and Jones matrices. In the context of interference, the coherence of light is explained thoroughly. To understand fundamental limits of resolution which cannot be explained by geometrical optics, diffraction theory is applied to imaging. The angular spectrum method and evanescent waves are used to understand the inherent loss of information about subwavelength features during the propagation of light. The book ends with a study of the working principle of the laser.

Have you ever wondered why ventilation helps to cool down your hot chocolate? Do you know why a surfing suit keeps you warm? Why iron feels cold, while wood feels warm at room temperature? Or how air is transferred into aqueous liquids in a water treatment plant? How can we sterilize milk with the least amount of energy? Or how do we design a new cooling tower of a power plant?

Transport Phenomena addresses questions like these and many more, exploring a wide variety of applications ranging from industrial processes to daily life problems and even to bioprocesses in our own body.

In Transport Phenomena, the transport and transfer of momentum, heat and mass are studied. To understand these processes which often take place simultaneously, the underlying concepts will be covered in this course.

If you’re a coastal engineer, ecologist or planner, then this is the course for you. You already know that engineering and ecological principles are not enough to realize nature-friendly solutions in practice. You need people on your side!

In this course you will learn how to build a relevant coalition of stakeholders to support the design and implementation of ecosystem-based hydraulic infrastructures. After learning basic stakeholder mapping and game theory techniques, you will apply Social Design Principles to a Building with Nature ecosystem-based design case. This will equip you to identify promising collaborative arrangements for your engineering or planning practice.

The course builds on the previous Building with Nature MOOC, which explored the use of natural materials and ecological processes in achieving effective and sustainable hydraulic infrastructure designs, distilling Engineering and Ecological Design Principles. In this course, the missing element of Social Design Principles are developed and taught.

You’ll learn from renowned Dutch engineers and international environmental scientists, who work at the technical- governance interface. Iconic examples such as the Maasvlakte II expansion to Rotterdam Harbor and the Delfland Sand Engine Mega-nourishment serve as study material. The challenges in designing and implementing these nature-friendly hydraulic infrastructures are explored by the eminent professors who were responsible for their genesis.

Join us in becoming one of the new generation of engineers, ecologists and planners who see the Building with Nature integrated design approach as critical to hydraulic engineering, nature and society.

While big data infiltrates all walks of life, most firms have not changed sufficiently to meet the challenges that come with it. In this course, you will learn how to develop a big data strategy, transform your business model and your organization.

This course will enable professionals to take their organization and their own career to the next level, regardless of their background and position.

Professionals will learn how to be in charge of big data instead of being subject to it. In particular, they will become familiar with tools to:

assess their current situation regarding potential big data-induced changes of a disruptive nature,
identify their options for successfully integrating big data in their strategy, business model and organization, or if not possible, how to exit quickly with as little loss as possible, and
strengthen their own position and that of their organization in our digitalized knowledge economy
The course will build on the concepts of product life cycles, the business model canvas, organizational theory and digitalized management jobs (such as Chief Digital Officer or Chief Informatics Officer) to help you find the best way to deal with and benefit from big data induced changes.

The course Bio-Inspired Design gives an overview of non-conventional mechanical approaches in nature and shows how this knowledge can lead to more creativity in mechanical design and to better (simpler, smaller, more robust) solutions than with conventional technology. The course discusses a large number of biological organisms with smart constructions, unusual mechanisms or clever sensing and processing methods and presents a number of technical examples and designs of bio-inspired instruments and machines.

Biomechatronics is a contraction of biomechanics and mechatronics. In this course the function and coordination of the human motion apparatus is the central focus, and the design of assistive devices for the support of the function of the motion apparatus.

Have you ever asked what “biobased” means or wondered about the key aspects in developing and commercializing biobased products? This course will answer those questions and more; highlighting the opportunities, hurdles, and driving forces of the bioeconomy.

Today’s industries face enormous global challenges when it comes to the fossil-based economy. Fossil resources are no longer a desirable feedstock for many products and governments’ climate goals put various limitations to its usage. Moreover, consumer perception has become an increasingly important factor. With biobased products as an alternative to the fossil-based economy, the bioeconomy can provide viable solutions to these challenges.

The course describes the different types of biomass, the methods of refinery and typical conversion technologies used for biobased products. You’ll also engage in a study of the practical and real-life examples emerging in the market: biopolymers, bioenergy, bioflavours, and biosurfactants.

The course has been developed by a team of experts from seven different institutions and universities in three different countries, all sharing their personal perspectives on the opportunities and challenges faced by the biobased industry. The three top-ranked institutions Delft University of Technology, RWTH Aachen University, and Wageningen University & Research offer additional, more advanced courses to continue your learning journey:

There is no doubt that the quantum computer and the quantum internet have many profound applications, they may change the way we think about information, and they could completely change our daily life.

But how do a quantum computer and a quantum internet work? What scientific principles are behind it? What kind of software and protocols do we need for that? How can we operate a quantum computer and a quantum internet? And which disciplines of science and engineering are needed to develop a fully working system?

In a series of two MOOCs, we will take you through all layers of a quantum computer and a quantum internet. The first course will provide you with the scientific basis by explaining the first layer: the qubits. We will discuss the four types of qubits that QuTech research center at Delft University of Technology focuses on: topological qubits, Spin qubits, Trans qubits and NV Centre qubits. We will teach you the working principles of qubits and, at the same time, the working principles of a computer made of these qubits.

In the upcoming second course, we will introduce the other layers needed to build a quantum computer and a quantum internet, such as the micro-architecture, compilers, quantum error correction, repeaters and quantum algorithms.

These two courses offer you an opportunity to deepen your knowledge by continuing the journey started in our first MOOC, which focused on the applications of a quantum computer and a quantum internet.

Note that these courses offer a full overview of the layers of a quantum computer and a quantum internet, and therefore they will not go into too much detail per layer. For learners seeking to fully understand one specific topic we can recommend other courses authored by QuTech:

Urban design, inequality and segregation are strongly connected.

Cities around the world, from the Global South to the Global North, are facing a rise in inequality and socio-economic segregation. The wealthy are increasingly concentrating in the most attractive urban areas and poverty is spreading to the suburbs. Rising levels of segregation have major consequences for the social sustainability of cities and leads to unequal life opportunities depending on where in the city you live.

In this course, aimed at a broad range of professionals, from urban planners and architects to geographers, you will learn what the main drivers and indicators of urban inequality and segregation are, using examples from cities from all over the world. You will learn how segregation is measured, how to interpret the results of the analyses of segregation and how to relate these insights to urban design. With this knowledge, you will be able to analyze how these issues may be affecting your local environment.

Additionally, we will present some historical examples of how urban design has played a role shaping spatial inequality and segregation in a selection of case study cities. This will help you to get a better understanding of how urban design can reduce spatial inequality and segregation.

The course is taught by the editors of the new SpringerOpen book “Urban socio-economic segregation and income inequality. A global perspective” and senior experts from the Urban Design section of TU Delft, which is ranked number 2 in the QS World University Rankings in the field of Architecture.
