Students learn how the innovative engineering of photovoltaics enables us to transform the sun’s energy into usable power—electricity—through the use of photovoltaic cells. Watching a short video clip from “The Martian” movie shows the importance of photovoltaics in powering space exploration at extreme distances from the Earth. Then students learn that the photovoltaic technologies designed to excel in the harsh environment of space have the potential to be just as beneficial on Earth—providing electricity-generating systems based on renewable energy sources is important for our electricity-gobbling society. Two student journaling sheets assist with vocabulary and concepts.

Students explore energy efficiency, focusing on renewable energy, by designing and building flat-plate solar water heaters. They apply their understanding of the three forms of heat transfer (conduction, convection and radiation), as well as how they relate to energy efficiency. They calculate the efficiency of the solar water heaters during initial and final tests and compare the efficiencies to those of models currently sold on the market (requiring some additional investigation by students). After comparing efficiencies, students explain how they would further improve their devices. Students learn about the trade-offs between efficiency and cost by calculating the total cost of their devices and evaluating cost per percent efficiency and per degree change of the water.
The 2014 Russia–Ukraine conflict has transformed relations between Russia and the West …
The 2014 Russia–Ukraine conflict has transformed relations between Russia and the West into what many are calling a new cold war. The West has slowly come to understand that Russia’s annexations and interventions, interference in elections, cyber warfare, disinformation, assassinations in Europe and support for anti-EU populists emerge from Vladimir Putin’s belief that Russia is at war with the West. This book shows that the crisis has deep roots in Russia’s inability to come to terms with an independent Ukrainian state, Moscow’s view of the Orange and Euromaidan revolutions as Western conspiracies and, finally, its inability to understand that most Russian-speaking Ukrainians do not want to rejoin Russia. In Moscow’s eyes, Ukraine is central to rebuilding a sphere of influence within the former Soviet space and to re-establishing Russia as a great power. The book shows that the wide range of ‘hybrid’ tactics that Russia has deployed show continuity with the actions of the Soviet-era security services.

Students explore how the efficiency of a solar photovoltaic (PV) panel is affected by the ambient temperature. They learn how engineers predict the power output of a PV panel at different temperatures and examine some real-world engineering applications used to control the temperature of PV panels.

This graduate seminar introduces an emerging research program within International Relations on territorial conflict. While scholars have recognized that territory has been one of the most frequent issues over which states go to war, territorial conflicts have only recently become the subject of systematic study. This course will examine why territorial conflicts arise in the first place, why some of these conflicts escalate to high levels of violence and why other territorial disputes reach settlement, thereby reducing the likelihood of war. Readings in the course draw upon political geography and history as well as qualitative and quantitative approaches to political science.

Students learn about wind as a source of renewable energy and explore the advantages and disadvantages wind turbines and wind farms. They also learn about the effectiveness of wind turbines in varying weather conditions and how engineers work to create wind power that is cheaper, more reliable and safer for wildlife.

This course is taught in four main parts. The first is a review of fundamental thermodynamic concepts (e.g. energy exchange in propulsion and power processes), and is followed by the second law (e.g. reversibility and irreversibility, lost work). Next are applications of thermodynamics to engineering systems (e.g. propulsion and power cycles, thermo chemistry), and the course concludes with fundamentals of heat transfer (e.g. heat exchange in aerospace devices)
Aspects of the tragic as a mode of literature and a quality …
Aspects of the tragic as a mode of literature and a quality of lived experience pursued in readings that extend from the warfare of the ancient world to the experiences of modern life. Authors include Aeschylus, Sophocles, Euripides, Shakespeare, Balzac, Tolstoy, Ibsen, Conrad, Dinesen, Faulkner, and Camus. Includes viewing of at least two films. "Tragedy" is a name originally applied to a particular kind of dramatic art and subsequently to other literary forms; it has also been applied to particular events, often implying thereby a particular view of life. Throughout the history of Western literature it has sustained this double reference. Uniquely and insistently, the realm of the tragic encompasses both literature and life. Through careful, critical reading of literary texts, this subject will examine three aspects of the tragic experience: The scapegoat; The tragic hero; The ethical crisis. These aspects of the tragic will be pursued in readings that range in the reference of their materials from the warfare of the ancient world to the experience of the modern extermination camps.

Students are introduced to the concepts of torque, power, friction and gear ratios. Teams modify two robotic LEGO® MINDSTORMS® vehicles by changing their gear ratios, wheel sizes, weight and engine power, while staying within a limit of points to spend on modifications. The robots face each other on a track with a string attaching one to the other. The winning robot, the one with the best adjustments, pulls the other across the line.

This is a seminar about the ways that urban design contributes to the distribution of political power and resources in cities. "Design," in this view, is not some value-neutral aesthetic applied to efforts at urban development but is, instead, an integral part of the motives driving that development. The class investigates the nature of the relations between built form and political purposes through close examination of a wide variety of situations where public and private sector design commissions and planning processes have been clearly motivated by political pressures, as well as situations where the political assumptions have remained more tacit. We will explore cases from both developed and developing countries.

Students learn the history of the waterwheel and common uses for water turbines today. They explore kinetic energy by creating their own experimental waterwheel from a two-liter plastic bottle. They investigate the transformations of energy involved in turning the blades of a hydro-turbine into work, and experiment with how weight affects the rotational rate of the waterwheel. Students also discuss and explore the characteristics of hydroelectric plants.

During this activity, students learn how oil is formed and where in the Earth we find it. Students take a core sample to look for oil in a model of the Earth. They analyze their sample and make an informed decision as to whether or not they should "drill for oil" in a specific location.

Students research the feasibility of installing a wind-turbine distributed energy (DE) system for their school. They write a proposal (actually, the executive summary of a proposal) to the school principal based on their findings and recommendations. While this activity is geared towards fifth-grade and older students, and Internet research capabilities are required, some portions of this activity may be appropriate for younger students.

A large part of engineering involves presenting products, concepts, and proposals to others in order to gain approval, funding, contracts, etc. The purpose of this activity is to fine-tune students' presentation skills while allowing them to independently investigate one type of power production to meet the needs of their region of choice. Students also learn problem solving skills in examining the advantages and disadvantages of particular methods of power generation.

Investigating a waterwheel illustrates to students the physical properties of energy. They learn that the concept of work, force acting over a distance, differs from power, which is defined as force acting over a distance over some period of time. Students create a model waterwheel and use it to calculate the amount of power produced and work done.
