This course will focus on basic technologies for the treatment of urban sewage. Unit processes involved in the treatment chain will be described as well as the physical, chemical and biological processes involved. There will be an emphasis on water quality and the functionality of each unit process within the treatment chain. After the course one should be able to recognize the process units, describe their function and make simple design calculations on urban sewage treatment plants.
This course discusses the evolution and role of urban public transportation modes, systems, and services, focusing on bus and rail. It covers various topics, including current practice and new methods for data collection and analysis, performance monitoring, route design, frequency determination, vehicle and crew scheduling, effect of pricing policy and service quality on ridership.
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.
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.
Hydraulic transients (also known as water hammer) can seem innocuous in a residential setting, but these spikes in pressure can cause major damage to large pipelines and industrial pipe networks. In this video, we briefly discuss how water hammer occurs and how engineers mitigate the effect.
The Visiting Professorship of Opera is funded by New College, and invites leading figures in the operatic world to Oxford each year to give instruction and practice in their areas of expertise. Professors take up residence for short periods while they are involved in a variety of sessions which will include lectures, symposia, masterclasses and performance. Events are open to student and public audiences alike.
China and the West: Music, Representation, and Reception' is the first book to explore how Chinese and Western musical materials and traditions—those involving instruments, melodies, rhythms, staged diversions (including operas and musical comedies), concert works, film scores, and digital recordings of several kinds—have gradually moved closer together and become increasingly accepted, as well as exploited, in Asia as well as Europe and North America. Although aimed in large part at a scholarly audience, China and the West should appeal to general readers of many kinds: those interested in politics, cultural history and theory, gender studies, sociology, theater, and media studies as well as musical composition and performance of ‘classical’ as well as traditional and popular kinds.
This is a demo of a bell siphon I built in collaboration with a couple of engineering professors. There are certain cases where it would be nice to be able to create a siphon without any intervention, a self-priming or automatic siphon: the next level of siphonry. It's built out of an acrylic sheet and a piece of clear pipe.
In general, and compared to other common building materials, metals have excellent mechanical properties. They are hard, tough, strong, and durable. As someone who occasionally works the wood, even I can admit that metals are a superior material in many regards. So you can see why it would be advantageous to have a way to connect them together, especially if you can do it in such a way that joint isn’t the weakest part of your assembly. That’s the goal of welding, and luckily, this is not something reserved for industrial factories and machine shops. From my own experiences so far, welding is something you might be able to do yourself as a hobby. And stay tuned till the end for some tips for getting started.
In civil engineering, quicksand is more than just a puddle of mud! The "quick condition" occurs when seepage reduces the effective stress of a soil. This can lead to some dangerous conditions, especially if the seepage causes piping erosion to occur at a dam.
