Dams

Rating

Through eight lessons, students are introduced to many facets of dams, including their basic components, the common types (all designed to resist strong forces), their primary benefits (electricity generation, water supply, flood control, irrigation, recreation), and their importance (historically, currently and globally). Through an introduction to kinetic and potential energy, students come to understand how dams generate electricity. They learn about the structure, function and purpose of locks, which involves an introduction to Pascal's law, water pressure and gravity. Other lessons introduce students to common environmental impacts of dams and the engineering approaches to address them. They learn about the life cycle of salmon and the many engineered dam structures that aid in their river passage, as they think of their own methods and devices that could help fish migrate past dams. Students learn how dams and reservoirs become part of the Earth's hydrologic cycle, focusing on the role of evaporation. To conclude, students learn that dams do not last forever; they require ongoing maintenance, occasionally fail or succumb to "old age," or are no longer needed, and are sometimes removed. Through associated hands-on activities, students track their personal water usage; use clay and plastic containers to model and test four types of dam structures; use paper cups and water to learn about water pressure and Pascal's Law; explore kinetic energy by creating their own experimental waterwheel from two-liter plastic bottles; collect and count a stream's insects to gauge its health; play an animated PowerPoint game to quiz their understanding of the salmon life cycle and fish ladders; run a weeklong experiment to measure water evaporation and graph their data; and research eight dams to find out and compare their original purposes, current status, reservoir capacity and lifespan. Woven throughout the unit is a continuing hypothetical scenario in which students act as consulting engineers with a Splash Engineering firm, assisting Thirsty County in designing a dam for Birdseye River.

Decimals, Fractions & Percentages

Decimals, Fractions & Percentages

Rating

Students learn about and practice converting between fractions, decimals and percentages. Using a LEGO® MINDSTORMS® NXT robot and a touch sensor, each group inputs a fraction of its choosing. Team members convert this same fraction into a decimal, and then a percentage via hand calculations, and double check their work using the NXT robot. Then they observe the robot moving forward and record that distance. Students learn that the distance moved is a fraction of the full distance, based on the fraction that they input, so if they input ½, the robot moves half of the original distance. From this, students work backwards to compute the full distance. Groups then compete in a game in which they are challenged to move the robot as close as possible to a target distance by inputting a fraction into the NXT bot.

Decision Making Under Uncertainty: Introduction to Structured Expert Judgment

Rating

In an increasingly data-driven world, data and its use aren’t always all it’s cracked up to be. This course aims to address the critical lack of any or appropriate data in many areas where complex decisions need to be made.

For instance, how can you predict volcano activity when no eruptions have been recorded over a long period of time? Or how can you predict how many people will be resistant to antibiotics in a country where there is no available data at national level? Or how about estimating the time needed to evacuate people in flood risk areas?

In situations like these, expert opinions are needed to address complex decision-making problems. This course, aimed at researchers and professionals from any academic background, will show you how expert opinion can be used for uncertainty quantification in a rigorous manner.

Various techniques are used in practice. They vary from the informal and undocumented opinion of one expert to a fully documented and formal elicitation of a panel of experts, whose uncertainty assessments can be aggregated to provide support for complex decision making.

In this course you will be introduced to state-of-the-art expert judgment methods, particularly the Classical Model (CM) or Cooke’s method, which is arguably the most rigorous method for performing Structured Expert Judgment.

CM, developed at TU Delft by Roger Cooke, has been successfully applied for over 30 years in areas as diverse as climate change, disaster management, epidemiology, public and global health, ecology, aeronautics/aerospace, nuclear safety, environment and ecology, engineering and many others.

Delay Insentitive Circuits -- Structures, Semantics, and Strategies

Rating

The design of concurrent distributed hardware systems is a major challenge for engineers today and is bound to escalate in the future, but engineering education continues to emphasize traditional tools of logic design that are just not up to the job. For engineers tackling realistic projects, improvised attempts at synchronization across multiple clock domains have long been a fact of life. Prone to hazards and metastability, these ad hoc interfaces could well be the least trustworthy aspects of a system, and typically also the least able to benefit from any readily familiar textbook techniques of analysis or verification.

Progress in the long run depends on a change of tactics. Instead of the customary but inevitably losing battle to describe complex systems in terms of their stepwise time evolution, taking their causal relationships and handshaking protocols as a starting point cuts to the chase by putting the emphasis where it belongs. This way of thinking may call for setting aside a hard earned legacy of practice and experience, but it leads ultimately to a more robust and scalable methodology.

Delay insensitive circuits rely on local coordination and control from the ground up. The most remarkable consequence of adhering to this course is that circuits can get useful things done without any clock distribution network whatsoever. Because a handshake acknowledgment concludes each interaction among primitive components and higher level subsystems alike, a clock pulse to mark them would be superfluous. This effect can bring a welcome relief to projects whose timing infrastructure would otherwise tend to create more problems than it solves.

The theory of delay insensitive circuits is not new but has not yet attracted much attention outside of its research community. At best ignored and at worst discouraged in standard curricula, this topic until now has been accessible only by navigating a sea of conference papers and journal articles, some of them paywalled. Popular misconceptions and differing conventions about terminology and notation have posed further barriers to entry. To address this need, this book presents a unified account of delay insensitive circuits from first principles to cutting edge concepts, subject only to an undergraduate-level understanding of discrete math. In an approachable tutorial format with numerous illustrations, exercises, and over three hundred references, it guides an engineering professional or advanced student towards proficiency in this extensive field.

Delft Design Approach

Rating

In our daily lives we use hundreds or even thousands of products and services. They are all designed, some with more success than others. The ‘Delft Design Approach’ is a structured approach that helps designers to tackle complex design challenges: from formulating a strategic vision, to mapping user behaviors, their needs and their environment, to developing and selecting meaningful proposals for products and services.

DDA691x offers a college-level introduction to the Delft Design Approach through lectures and exercises on design fundamentals and 6 methods. You will understand basic models and concepts that underlie the Delft approach. You will also develop the capability to use 6 basic methods in a design context. You will do so by applying the methods to realistic design challenges and by reflecting on your own performance by comparing it to that of expert designers as well as through peer discussion.

The Delft Sand, Clay & Rock Cutting Model

Rating

In dredging, trenching, (deep sea) mining, drilling, tunnel boring and many other applications, sand, clay or rock has to be excavated. This book gives an overview of cutting theories. It starts with a generic model, which is valid for all types of soil (sand, clay and rock) after which the specifics of dry sand, water saturated sand, clay, atmospheric rock and hyperbaric rock are covered. For each soil type small blade angles and large blade angles, resulting in a wedge in front of the blade, are discussed. For each case considered, the equations/model for the cutting forces, power and specific energy are given. The models are verified with laboratory research, mainly at the Delft University of Technology, but also with data from literature.
