Two courses published: Introduction to Drinking Water Treatment and Introduction to Credit Risk Management
Since January two new former MOOCs have been published:
Introduction to Drinking Water Treatment
Learn about urban water services, focusing on conventional technologies for drinking water treatment.
This course focuses on conventional technologies for drinking water treatment. Unit processes, involved in the treatment chain, are discussed as well as the physical, chemical and biological processes involved. The emphasis is on the effect of treatment on water quality and the dimensions of the unit processes in the treatment chain. After the course one should be able to recognise the process units, describe their function, and make basic calculations for a preliminary design of a drinking water treatment plant.
Introduction to Credit Risk Management
What is credit risk? Why is it so important, in modern economies, to correctly deal with it? This course combines theory with practice to answer these questions.
You are a bank and a big part of your daily business is to lend money. Unfortunately for you, lending money is definitely a risky activity: there is no 100% guarantee that you will get all your money back. For example you may expect losses in your portfolio because of the default of your counterpart. Or, in a less extreme situation, the credit quality of your counterpart may deteriorate according to some rating system, so that your loan becomes more and more risky. These are typical situations in which credit risk manifests itself. According to the Basel Agreements, credit risk is one of the three fundamental risks, together with market risk and operational risk, a bank (or another regulated financial institution) has to face when operating on the markets. As the 2008 financial crisis has shown us, a correct understanding of credit risk and the ability to cope with it are fundamental in the world of today. The aim of this course is to provide an introduction to credit risk modeling and hedging. At the end of the course, the students will be able to understand and correctly use the basic tools of credit risk management, both from a theoretical and, most of all, a practical point of view. This will be a quite unconventional course. For every methodology, we will analyze its points of strengths, but we will also stress its points of weakness. We will try to do this in a rigorous way, but also with fun. In addition to the video lectures and exercises, recent economic developments will be discussed in the forum based on news articles, and key practitioners from the financial world will share their views through interviews.
At the end of December two courses published in OpenCourseWare:
Both are former MOOC’s
Technology for Biobased Products
As fossil-based fuels and raw materials contribute to climate change, the use of renewable materials and energy as an alternative is in full swing. This transition is not a luxury, it is has become a necessity. We can use the unique properties of microorganisms to convert organic waste streams into biomaterials, chemicals and biofuels. This course provides the insights and tools for biotechnological processes design in a sustainable way. Five experienced course leaders will teach you the basics of industrial biotechnology and how to apply these to the design of fermentation processes for the production of fuels, chemicals and foodstuffs. Throughout the course, you will be challenged to design your own biotechnological process and evaluate its performance and sustainability.
Solving Complex Problems
Solving Complex Problems addresses complex multi-actor systems; so called ‘spaghetti situations’ in which everything is connected to everything, and everything influences everything. Situations, for instance, in which innovative new energy technologies emerge into the existing energy system. Or new health technology, medicine, treatments or screening technologies are being developed and society has to decide about whether they should be allowed and what they may cost.
Want to know more about these free courses and other OpenCourseWare courses go to TU Delft OpenCourseWare
Open Education Week’s goal is to raise awareness about free and open educational opportunities. At TU Delft we want to highlight how open education can help people meet their goals in education, whether that’s to develop skills and knowledge for work, supporting formal studies, learning something new for personal interest, or looking for additional teaching resources. Therefore, starting March 9th, we kick off the Open Education Week 2015. The perfect opportunity for (teaching) staff and students to discover more about the possibilities of online and open education. During the Open Education Week we organize several activities about open and online education.

today a new course has been published: Advanced Design and Optimization of Composite Structures I, a master course of Aerospace Engineering
This course introduces the basic components of an airframe structure and discusses their use and limitations. The realities of composite design such as the effect of material scatter, environmental knockdowns, and damage knockdowns are discussed and guidelines accounting for these effects and leading to robust designs are presented. The resulting design constraints and predictive tools are applied to real-life design problems in composite structures. A brief revision of lamination theory and failure criteria leads into the development of analytical solutions for typical failure modes for monolithic skins (layup strength, buckling under combined loads and for a variety of boundary conditions) and stiffeners (strength, column buckling under a variety of loads and boundary conditions, local buckling or crippling for one-edge and no-edge-free conditions). These are then combined into stiffened composite structures where additional failure modes such as skin-stiffener separation are considered. Analogous treatment of sandwich skins examines buckling, wrinkling, crimping, intra-cellular buckling failure modes. Once the basic analysis and design techniques have been presented, typical designs (e.g. flange layup, stiffness, taper requirements) are presented and a series of design guidelines (stiffness mismatch minimization, symmetric and balanced layups, 10% rule, etc.) addressing layup and geometry are discussed. On the metal side, the corresponding design practices and analysis methods are presented for the more important failure modes (buckling, crippling) and comparisons to composite designs are made. A design problem is given in the end as an application of the material in this part of the course.

A new course Next Generation Infrastructures part 1 has been published, the course is a former MOOC from the faculty Technology, Policy and Management: http://bit.ly/Z4ad2i
Infrastructures for energy, water, transport, information and communications services create the conditions for livability and economic development. They are the backbone of our society. Similar to our arteries and neural systems that sustain our human bodies, most people however take infrastructures for granted. That is, until they break down or service levels go down.
In many countries around the globe infrastructures are ageing. They require substantial investments to meet the challenges of increasing population, urbanization, resource scarcity, congestion, pollution, and so on. Infrastructures are vulnerable to extreme weather events, and therewith to climate change.
Technological innovations, such as new technologies to harvest renewable energy, are one part of the solution. The other part comes from infrastructure restructuring. Market design and regulation, for example, have a high impact on the functioning and performance of infrastructures.
This course will help you to understand the complexity of infrastructure systems. Complexity is one of key words of this course and we will describe the tremendous implications for the design and governance of infrastructure systems. Part II of the MOOC NGI (September/Otober 2014) will have a more applied nature: the focus will be on smart, secure and sustainable infrastructures ( smart grids, eco cities, ICT/big data &performance of infrastructures and asset management).
The MOOC: Next Generation Infrastructures – Part 2 will start 21 September 2014

Last week a new master course of Mechanical Engineering has been published: Mechatronic System Design.
Mechatronic system design deals with the design of controlled motion systems by the integration of functional elements from a multitude of disciplines. It starts with thinking how the required function can be realised by the combination of different subsystems according to a Systems Engineering approach (V-model).
Some supporting disciplines, like power-electronics and electromechanics, are not part of the BSc program of mechanical engineers. For this reason this course introduces these disciplines in connection with PID-motion control principles to realise an optimally designed motion system.
The target application for the lectures are motion systems that combine high speed movements with extreme precision.
The course covers the following four main subjects:
Dynamics of motion systems in the time and frequency domain, including analytical frequency transfer functions that are represented in Bode and Nyquist plots.
Motion control with PID-feedback and model-based feedforward control-principles that effectively deal with the mechanical dynamic anomalies of the plant.
Electromechanical actuators, mainly based on the electromagnetic Lorentz principle. Reluctance force and piezoelectric actuators will be shortly presented to complete the overview.
Power electronics that are used for driving electromagnetic actuators.
The fifth relevant discipline, position measurement systems is dealt with in another course: WB2303, Electronics and measurement.
The most important educational element that will be addressed is the necessary knowledge of the physical phenomena that act on motion systems, to be able to critically judge results obtained with simulation software.
The lectures challenge the capability of students to match simulation models with reality, to translate a real system into a sufficiently simplified dynamic model and use the derived dynamic properties to design a suitable, practically realiseable controller.
This course increases the understanding what a position control system does in reality in terms of virtual mechanical properties like stiffness and damping that are added to the mechanical plant by a closed loop feedback controller.
It is shown how a motion system can be analysed and modelled top-down with approximating (scalar) calculations by hand, giving a sufficient feel of the problem to make valuable concept design decisions in an early stage.
With this method students learn to work more efficiently by starting their design with a quick and dirty global analysis to prove feasibility or direct further detailed modelling in specific problem areas.
Last week a new course of the Master Aerospace Engineering has been published: Advanced Structural Analysis
