    Why Concrete Needs Reinforcement

    Why Concrete Needs Reinforcement

    This video shows more destructive testing to answer your questions about concrete. Concrete's greatest weakness is its tensile strength, which can be less than 10% of its compressive strength. So, we often reinforce it to create a composite material strong against all types of stress. This video briefly touches on conventional rebar and prestressed/post-tensioned reinforcement.

    Why Bridges Move...

    Why Bridges Move...

    This video explains why ridges move, and other musings on thermal movement of large civil works. Most people have a certain intuition about thermal expansion, but you may not have considered how engineers design to accommodate it on large civil structures. The video gives a quick overview on this important consideration that engineers must account for when designing infrastructure like pipelines, bridges, and even sidewalks.

    What's in Your (Customer's) Wallet?

    What's in Your (Customer's) Wallet?

    This video was recorded at 16th ACM SIGKDD International Conference on Knowledge Discovery and Data Mining (KDD), Washington 2010. In 2009 IBM was recognized as a finalist of the INFORMS Edelman competition for its predictive modeling initiative to improve the productivity of its global salesforce and with an estimated business impact of ~ 100 Million dollars. The first component implements some traditional propensity modeling to identify new sales opportunities and is currently used by over 13,000 sales reps. The second 'wallet estimation' component is used strategically to allocate sales resources based on validated analytical estimates of revenue opportunity. In this case study we cover the key elements leading to the success including the data integration, data mining and predictive modeling, solution delivery, human guided model validation, integration of the business process and we conclude with an assessment of the bottom-line business impact.

    What is plagiarism

    What is plagiarism

    In this video, Mr Peter Sidorko, the University Librarian of the University of Hong Kong explain the importance of academic integrity. Students are expected to conduct themselves honesty and with integrity. One of the key responsibilities is to assure to credit the materials used to develop the ideas and academic work properly and avoid plagiarism.

    What is a scholarly journal article?

    What is a scholarly journal article?

    Chances are you'll need to find a scholarly journal article for a research paper or project in the near future. But, wait, what is a "scholarly journal article?" How is it different from a popular source like a newspaper or magazine article? Let's reduce the confusion on scholarly journal articles. Scholarly journals enable scholars -- experts in a particular academic field -- to communicate their research with other experts in that field through publishing articles and to stay current by reading about other scholars' work. Consequently, scholarly journals create a community of scholars who are all participating in a kind of "conversation" in that academic field. Rather than a face-to-face conversation, this is a formal conversation, which takes place over months and years through written documents. The most important part of this long term written conversation - what makes it a “scholarly” conversation, as opposed to popular - is what's called the “peer review process.” The peer review process works like this: in order for a scholar to get published in a scholarly journal, his or her expert peers must read their work and critique it. These “peer reviewers” make sure that the scholar has cited the appropriate experts in the discipline, made valid and well-supported arguments, and has written the article on a topic that is appropriate for that particular journal. This rigorous evaluation process ensures that scholarly work meets a higher standard than popular publications. So, why is this important for you? First, the information in a scholarly text has been rigorously evaluated, so it is more reliable and credible than information in popular sources. Second, reading scholarly journal articles for your papers or projects can give you insight into the ways of thinking of experts in that field. Finally, every scholarly text has extensive bibliographies that introduce you to important texts in the field, which can help you extend your research in that area. When you read the articles and books the scholar cited in her article, you are taking part in the scholarly conversation.

    What is a Weir?

    What is a Weir?

    A weir is a small dam built across a river to control the upstream water level. Weirs have been used for ages to control the flow of water in streams, rivers, and other water bodies. Unlike large dams which create reservoirs, the goal of building a weir across a river isn’t to create storage, but only to gain some control over the water level. Over time, the term weir has taken on a more general definition in engineering to apply to any hydraulic control structure that allows water to flow over its top, often called its crest. In fact, the spillways of many large dams use weirs as control structures. So how do they work?

    What is a Tuned Mass Damper?

    What is a Tuned Mass Damper?

    In many of the world’s tallest skyscrapers, there’s a secret device protecting the building and the people inside from strong motion due to wind and earthquakes. Did you know you can tune a skyscraper just like a guitar? In this video, we’re comparing theory to the real world for tuned mass dampers. Luckily this tech is simple enough that we can model it right in the garage. As silly as this little experiment looks, it’s actually not that far off from what engineers do in the real world (maybe without the googly eyes). The design phase for just about every major building includes some physical scale model tests. This video shows that the tuned mass damper is a great example of elegance in engineering.

    What is a Hydraulic Jump?

    What is a Hydraulic Jump?

    Engineers need to be able to predict how water will behave in order to design structures that manage or control it. And fluids don’t always behave the way you’d expect. On this episode, we’re talking about one of the most interesting phenomena in open-channel flow: the hydraulic jump.
