How do we deal with the challenges and threats to vernacular architecture and make sure that it is sustained in this modern urbanized world? This is the key question we will try to answer in this course.

This architecture course takes you on a journey of understanding and appreciating the value of our everyday built environment. In the first two modules, we will explore the deeper socio-cultural meaning of rural vernacular architecture and look at the urban vernacular and challenges of people migrating from villages to live in cities; in module 3, we will focus on what we call ‘informal settlements’ in Asian cities; and in the final two modules, we will explore answers to a few questions that are very relevant to the current status and future development of vernacular architecture, such as:

• How can we conserve and sustain our vernacular cultural heritage?
• How can we reconcile tradition with modernity and originality?

We will also cast our eyes into the future, and discuss how the field of vernacular architecture might evolve and develop in the years to come.

Ultimately, the goal of this 5-week course is to help you establish your own viewpoints about the more complex or even contradictory issues in vernacular architecture, so you can make informed decisions regarding the protection and conservation of your local vernacular environments.

Special note: This course can be taken independently from The Search of Vernacular Architecture of Asia, Part 1.

Terrorism has gone from a persistent yet marginal security concern to one of the most important security problems of our day. There are few countries that do not suffer from some form of terrorism. Though many attempts at terrorism fail, some groups wage lengthy and bloody campaigns and, in exceptional cases, kill hundreds or even thousands in pursuit of their ends.

This course on terrorism will explore the nuances involved in defining terrorism, the nature of Al Qaeda, the Islamic State, and other important groups, the effectiveness of different counterterrorism tools, terrorist recruiting, counterterrorism and the rule of law, the political context in the Middle East, and the terrorist use of technology.

For those interested in a more extended version of the course, the full 7-section course Terrorism and Counterterrorism is available here.

This finance course will expose learners to the workings of global financial markets, their key institutional features, and the theoretical underpinnings of their design. Topics will include different types of financial securities such as debt, equity, convertible debt, and preferred stocks traded in the market, their relative advantages and disadvantages and the roles of institutions such as banks, credit rating agencies and institutional investors (such as pension funds and activist investors) in these markets.

The course will critically evaluate the risk-return tradeoff inherent in different financial instruments, and how managers should think about using these instruments for their firms. The course will introduce the idea of information asymmetry and conflicts of interests among various stakeholders of the firm and how various financial securities overcome these conflicts. This will be followed by a critical evaluation of recent financial crises within the context of these conflicts.

This course is for learners broadly interested in financial markets, managers working in corporations or institutions and individuals planning to pursue a graduate degree in business (MBA).

Through a combination of lectures, business case studies, and hands-on learning this course provides an introduction to data analytics techniques and their application in business.

The case studies explored will illustrate how companies are leveraging different sources of data, including “big data,” with different analytical techniques, to improve performance. You will receive hands-on learning through a free web-based graphical development environment that will allow you to practice using some of these tools themselves. You will also gain an understanding of the many possibilities for applying data science in business, and will be able to consider additional learning opportunities to gain further depth.

This course is an excellent resource for managers who see the opportunity to use data analytics in business but do not have the skills and background to engage with data analytics themselves.

How do we understand architecture? One way of answering this question is by looking through the lens of history, beginning with First Societies and extending to the 16th century. This course in architectural history is not intended as a linear narrative, but rather aims to provide a more global view, by focusing on different architectural "moments."

How did the introduction of iron in the ninth century BCE impact regional politics and the development of architecture? How did new religious formations, such as Buddhism and Hinduism, produce new architectural understandings? What were the architectural consequences of the changing political landscape in northern Italy in the 14th century? How did rock-cut architecture move across space and time from West Asia to India to Africa? How did the emergence of corn impact the rise of religious and temple construction in Mexico?

Each lecture analyzes a particular architectural transformation arising from a dynamic cultural situation. Material covered in lectures will be supplemented by readings from the textbook A Global History of Architecture.

Join us on a journey around the globe and learn how architecture has developed and interacted with the world’s culture, religion, and history.

Are you an engineer, scientist or technician? Are you dealing with measurements or big data, but are you unsure about how to proceed? This is the course that teaches you how to find the best estimates of the unknown parameters from noisy observations. You will also learn how to assess the quality of your results.

TU Delft’s approach to observation theory is world leading and based on decades of experience in research and teaching in geodesy and the wider geosciences. The theory, however, can be applied to all the engineering sciences where measurements are used to estimate unknown parameters.

The course introduces a standardized approach for parameter estimation, using a functional model (relating the observations to the unknown parameters) and a stochastic model (describing the quality of the observations). Using the concepts of least squares and best linear unbiased estimation (BLUE), parameters are estimated and analyzed in terms of precision and significance.

The course ends with the concept of overall model test, to check the validity of the parameter estimation results using hypothesis testing. Emphasis is given to develop a standardized way to deal with estimation problems. Most of the course effort will be on examples and exercises from different engineering disciplines, especially in the domain of Earth Sciences.

This course is aimed towards Engineering and Earth Sciences students at Bachelor’s, Master’s and postgraduate level.

A collection of inspiring & thought-provoking videos about education for a better world, and how we learn.

Opioids are part of a drug class that includes the illegal drug heroin as well as powerful pain relievers, such as oxycodone, hydrocodone, codeine, morphine, fentanyl, and many others. In 2015 more than 33,000 people died from overdoses involving opioids. Every day in the United States more than 1,000 people are treated in emergency departments for not using prescription opioids as directed. Drug overdose is now the leading cause of accidental death in the U.S., and opioid addiction is driving this epidemic.

This course challenges preconceptions about addiction and about who can become addicted to opioids. Our main goals are to reduce the stigma that exists around addiction, help prevent overdose deaths and encourage people to learn about the multiple pathways to treatment. You will learn about these topics from a variety of medical experts and hear from people who have experienced addiction themselves, or who have lost a family member to an overdose.
