This video shows how simple reinforcement is used to prevent collapse of rock tunnels. Tunnels play an important role in our constructed environment as passageways for mines, conveyance for utilities, and routes for transportation. Rock bolts are a type of reinforcement for stabilizing rock excavations, usually made from steel bars or bolts. This simple construction method dramatically reduces the cost of making tunnels through rock safe from collapse.

Water hammer can work in both directions, and I only discussed one of those in the previous video (https://youtu.be/xoLmVFAFjn4). This episode revisits that demonstration to show how water hammer can form a vacuum pressure in a pipe. Momentum carrying fluid away from a valve wants to keep going even after the valve is closed. This generates a negative pressure than can cause major damage!

Expansive soils cause more property damage per year than earthquakes, floods, hurricanes, and tornadoes combined. Expansive soils are a slow-moving geologic phenomenon, which makes them not very news-worthy. However, they still cause a tremendous amount of damage to buildings and the public infrastructure we rely on every day.

This video discusses the purpose and function of elevated water storage tanks. The job of finding enough water, making it safe to use, and then reliably distributing it to the system customers with almost no downtime is a monumental task that requires a lot of infrastructure. And, probably the most visible component of a public water system is the elevated storage tank, also known as a water tower.

A few things that can go very wrong when you put steam in a pipe. We talked about the damaging effects of water hammer, but there’s another state of H2O equally if not more dangerous when put in pipes. In this episode, we’re talking about steam hammer and differential shock.

Sometimes conventional reinforcement isn't enough. The basics of prestressed concrete. Prestressing reinforcement doesn't necessarily make concrete stronger. But, it does increase the serviceability of concrete members by reducing the amount of deflection under load. This video explains the two most common types of prestressed concrete: pre-tensioned and post-tensioned. Prestressed concrete is used in all kinds of structures from bridges to buildings to silos and tanks. It’s a great way to minimize cracking and take fuller advantage of the incredible strength of reinforced concrete.

This course provides a theoretical basis to model-based control design with the focus on systematically develop mathematical models from basic physical laws and to use them in control design process with specific focus on automotive applications. You will learn the basics of mathematical modeling applied to automotive systems, and based on the modeling framework different type of controller and state estimation methods will be introduced and applied. Starting from a pure state-feedback concept down to optimal control methods, with special attention on different automotive applications. Different methods for state reconstruction is also introduced and discussed in the course. Exercises play an important rolethroughout the course. This course is aimed at learners with a bachelor's degree or engineers in the automotive industry who need to learn more about mathematical modelling of automotive systems.

Responsive cities define the future of urbanization. They evolve from smart cities, with a fundamental difference: The citizens move from the center of attention to the center of action. Responsive citizens use smart technology to contribute to planning, design and management of their cities. Responsive cities are about bringing cities back to their citizens. Responsive cities change the way the technology of a smart city is used. The first Smart Cities were technology driven and they produced large amounts of data from fixed or centrally controlled sensors. But by now, the citizens and their mobile phones have taken the leading role in direct data generation. Rather than using data that are centrally collected and stored, you will see platforms on which the citizens place the data and the information they decide to share. With this, your own responsibility becomes a foundation of a Responsive City. Cities evolve from being smart to being responsive. To demonstrate the potential of Responsive Cities, this course will define the concept of Citizen Design Science, a combination of Citizen Design, Citizen Science and Design Science. Experts, citizens and scientists participate in Citizen Design Science. This approach is still in an early stage of development, but with the Responsive Cities Massive Open Online Course, you will be ahead in exploring and defining its possibilities. ‘Responsive cities’ is the fourth edition of the ‘Future Cities’ series on urban MOOCs. The ‘Future Cities’ series is the first and complete series of urban courses dealing with the design, management and transformation of cities for their sustainable and resilient future. With every edition, the series becomes more interactive. It increasingly empowers citizens around the world to become part of the development of their own cities, especially in those places where this knowledge is needed most. Therefore, the course is inclusive for every individual interested in the planning, construction, redevelopment and management of future cities. The course is open to anyone regardless of background, skills, knowledge, or age.

The principles of rock mechanics explains the fundamental concepts of continuum mechanics and rheology as applied in studies of rock deformation. A thorough understanding of rock behavior is essential for strategic planning in the petroleum and mining industry, in construction operation, and in locating subsurface repositories. The formation of geological structures or rock deformation patterns, studied by geodynamicists and tectonicians, is, also governed by the mechanical principles outlined in this textbook. The aim of the present book is obvious: to inspire a new generation of positively forward-thinking geoscientists and engineers, skillful in and favorable to the practical application of mechanics to rock structures.
