Modelling is about understanding the nature: our world, ourselves and our work. Everything that we observe has a cause (typically several) and has the effect thereof. The heart of modelling lies in identifying, understanding and quantifying these cause-and-effect relationships.

A model can be treated as a (selective) representation of a system. We create the model by defining a mapping from the system space to the model space, thus we can map system state and behaviour to model state and behaviour. By defining the inverse mapping, we may map results from the study of the model back to the system. In this course, using an overarching modelling paradigm, students will become familiar with several instances of modelling, e.g., mechanics, thermal dynamics, fluid mechanics, etc.

This course examines some of the most important political revolutions that took place between the 17th century and today, beginning with pre-revolutionary Europe and the Enlightenment and continuing with the English Revolution of the 17th century, the American and the French Revolutions, the Mexican Revolution, the Russian and the Chinese Revolutions, the Iranian Revolution, and finally, the Eastern European revolutions of 1989, which brought about radical changes without recourse to violence. Upon successful completion of this course, the student will be able to: provide a concise historical narrative of each of the revolutions presented in the course; identify the origins and causes of each revolution, and compare revolutions with respect to their causes; analyze the goals and ideals of the revolutionaries, and compare how these functioned in various modern revolutions; discuss how revolutions in various parts of the world have affected womenĺÎĺ_ĺĚĺ_s rights; analyze how religious and secular worldviews came into conflict during times of upheaval and revolution; discuss the patterns and dynamics of revolutionary violence, and evaluate how revolutionaries have used non violent tactics against oppressive regimes; evaluate connections between revolutionary ideologies and revolutionary events; analyze how the legacies of each revolution are present in modern politics; describe and evaluate competing theoretical models of revolutionary change; interpret primary historical documents.

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.

The course describes in a simple and practical way what non-equilibrium thermodynamics is and how it can contribute to engineering fields. It explains how to derive proper equations of transport from the second law of thermodynamics or the entropy production. The obtained equations are frequently more precise than used so far, and can be used to understand the waste of energy resources in central process units in the industry. The entropy balance is used to define the energy efficiency in energy conversion and create consistent thermodynamic models. It also provides a systematic method for minimizing energy losses that are connected with transport of heat, mass, charge and momentum. The entropy balance examines operation at the state of minimum entropy production and is used to propose some rules of design for energy efficient operation. For this course some knowledge of engineering thermodynamics is a prerequisite. The first and second law of thermodynamics and terms as entropy should be known before starting this course.

This course is about solving complex problems. Our favorite problems are not just technically complex but also characterized by the presence of many different social actors that hold conflicting interests, objectives, and perceptions and act strategically to get the best out of a problem situation. This course offers guidance for policy analysts who want to assess if and how their analysis could be of help, based on the premise that problem formulation is the cornerstone in addressing complex problems. After this course, students would have obtained a theoretical insight into different models of decision-making processes, their implications in terms of supporting decision making and the potential roles that analysts; they can make a structured problem analysis in a complex situation, and can lay down their findings in an ‰"issue paper‰;" they know how to use a range of different methods and techniques to support attainment of these objectives; can formulate plans for a further analysis and closer examination, including the specification and the choice of possible mathematical models to be used.The completion of the practical part of this course will be an issue paper (written in pairs).

The purpose of this course is to provide the student with a fundamental understanding of the principles of macroeconomics. Macroeconomists study how a country's economy works and try to determine the best choices to improve the overall wellbeing of a nation. Typical topics include inflation (the overall level of prices), employment, fiscal policy (government taxing and spending), and money and banking (interest rates and lending policies). By studying macroeconomics and understanding the critical ideas and tools used to measure economic data, the student will have a better perspective on the issues and problems discussed in contemporary economics. Upon successful completion of this course, the student will be able to: Discuss key macroeconomic concerns, including national income accounting, saving and investment, and market forces; Describe the determinants of total output and the ways to measure nominal Gross Domestic Product (GDP) as well as real GDP; Compare and contrast definitions of total employment and unemployment, the three forms of unemployment, and inflation; Explain different ways of computing the general movement in prices, and define the relationship between inflation and unemployment; Explain the model of aggregate demand and aggregate supply; Analyze the government's role in the economy and examine how it uses its fiscal policy and monetary policy to influence macroeconomic variables in order to enable macro and micro economic stability; Describe the mechanics of money supply in detail. They will specifically be able to identify different types of money; explain the money creation process, the money multiplier, and the process of interest rate determination; and discuss the role of the Federal Reserve System and its tools of monetary policy; Identify and analyze major theories of economic growth; Analyze various strategies for developing of less-developed nations; Present the concepts behind international trade.

The purpose of this course is to provide the student with a basic understanding of the principles of microeconomics. At its core, the study of economics deals with the choices and decisions that have to be made in order to manage scarce resources available to us. Microeconomics is the branch of economics that pertains to decisions made at the individual level, i.e. by individual consumers or individual firms, after evaluating resources, costs, and tradeoffs. "The economy" refers to the marketplace or system in which these choices interact with one another. In this course, the student will learn how and why these decisions are made and how they affect one another in the economy. Upon successful completion of this course, students will be able to: Think intuitively about economic problems; Identify how individual economic agents make rational choices given scarce resources and will know how to optimize the use of resources at hand; Understand some simplistic economic models related to Production, Trade, and the Circular Flow of Resources; Analyze and apply the mechanics of Demand and Supply for Individuals, Firms, and the Market; Apply the concept of Marginal Analysis in order to make optimal choices and identify whether the choices are 'efficient' or 'equitable'; Apply the concept of Elasticity as a measure of responsiveness to various variables; Identify the characteristic differences amongst various market structures, namely, Perfectly Competitive Markets, Non-Competitive Markets, and Imperfectly Competitive Markets and understand the differences in their operation; Analyze how the Demand and Supply technique works for the Resource Markets.
