• Preparing for the America's Cup: A technological and a human challenge

      Fischer, Martin (2017-01-17)
      The America's Cup is the pinnacle event in sailing and it is the oldest sports trophy in the world. The trophy was originally awarded in 1851 for a race around the Isle of Wight, which was won by the schooner ムAmericaメ. It was subsequently renamed after the yacht and was donated to the New York Yacht Club under the terms of the Deed of Gift, which made the Cup available for perpetual international competition. The 35th America's Cup will be held in May / June 2017 in Bermuda. The races will be sailed in 50-ft foiling catamarans. Instead of a main sail the boats feature a rigid wing. These boats are capable of sailing 3 times the wind speed, with top speeds reaching 45 knots. The lecture describes the technological and human endeavor to develop and prepare the boat and the crew. Developing an America's Cup boat is a multidisciplinary effort. Excellence is required in such different fields as aerodynamics, hydrodynamics, structural analysis, advanced composite engineering and building, design of mechanical control systems, hydraulics, electronics and flight control, to name the most important ones. Since automatic control systems (autopilots) are forbidden in the America's Cup rules there is a strong two-way feedback between sailing practicalities and the technological choices being made. Combine this with the management of a very tight build schedule for hulls, beams, foils, rudders and the wing and you get an idea what it means to prepare for the America's Cup.
    • From Exploration to Exploitation? Opportunities and Imperatives in the Deep Sea

      Van Dover, Cindy Lee (2017-01-16)
      We may think of the depths of the ocean as unseen, unfathomable, but there have been breakthroughs in technology that allow scientists access to the deep sea and that bring the deep sea directly to the public through live video feeds and data links. We can now map the seafloor to resolve features the size of a football and smaller using sound waves, while at the same time, sensors report to us the chemical nature of the surrounding environment. We will look at examples of robots and other assets that we use to explore the seafloor and at some of the discoveries that arise from our expanding capabilities. We will look at some of the blank places on the map and wonder what might be located there. And finally, we will explore the growing interest in mining the seabed and the potential for a Blue Economy in the deep ocean.

    • Choosing to Fly: Examining Fear, Risk and Resilience

      Davis, Steph (2017-01-15)
      Steph Davis was raised as a classical piano student in a traditional, academic family. She ultimately quit music and then law school, making the frightening decision to step off the safe road and follow her passion to become a full-time rock climber. In 25 years of climbing, Steph has applied the principles of discipline and practice she learned as a musician to reach the tops of some of the world's most difficult rock walls and mountains, often climbing solo without a rope or safety equipment. Intrigued by the power of fear and how it affects our ability to succeed and to stay safe, she learned to skydive as a literal way to face her own fears of falling. From skydiving, Steph immersed herself in the pursuit of wingsuit BASE jumping, known as the most advanced and dangerous form of human flight, in order to fly off mountains after climbing up them. Living and surviving in the mountains and the air, Steph has developed a deep understanding of the need to adapt to one's environment, to embrace failure and to come to terms with fear--skills which are also crucial for survival and success in any walk of life. After the loss of her husband on a wingsuit flight in the Dolomites, Steph saw that resilience is a choice. The decision to keep going forward and to embrace life fully in the face of loss is a simple and yet profound decision that we can all make, no matter what challenges we face. Simply by deciding that we want to go somewhere, whether physically or mentally, we've taken the first step to getting there.

    • Pushing the Limits of Kinetic Arts: Strandbeests

      Jansen, Theo (2017-01-12)
      In 1990, Dutch artist Theo Jansen introduced the world to his newest creation, the strandbeests. Kenetic sculptures created from plastic tubing, water bottles, and pipes, these beests survive on their own. These herds live on beaches all around the world, surviving on their waterfeelers and sandfeelers to remain safely on the sand. Powered by wind, these new life forms do not require food! Join us for a keynote lecture with Theo as he discusses the story behind the strandbeests as he pushes the limits with these beautiful and unique animals.
    • Hyperloop: The Future of Transportation

      Ahlborn, Dirk (2017-01-11)
      What is Hyperloop? Hyperloop is a new way to move people or things anywhere in the world quickly, safely, efficiently, on-demand and with minimal impact to the environment. The system, using updated technologies, by Elon Musk, relies on electric propulsion to accelerate a passenger or cargo vehicle through a tube in a low-pressure environment. The autonomous vehicle levitates slightly above the track and glides at faster-than-airline speeds over long distances. We eliminate direct emissions, noise, delay, weather concerns and pilot error. Itメs the next mode of transportation.

    • Intrinsic defect process and O migration in PrBa(Co/Fe)2O5.5

      Salawu, Omotayo Akande (2017-01-08)
      New mixed ion-electron conductors ar desired to lower the operating temperature of solid oxide fuel cells. The O Frenkel energy and migration of O ions in rBa(Co/Fe)2O5.5 are studied for this purpose by density functional theory. We demonstrate that Fe substitution strongly affects the formation of defects and consequently the O migration.
    • Minimum Delay Moving Object Detection

      Lao, Dong; Sundaramoorthi, Ganesh (2017-01-08)
      We present a general framework and method for detection of an object in a video based on apparent motion. The object moves relative to background motion at some unknown time in the video, and the goal is to detect and segment the object as soon it moves in an online manner. Due to unreliability of motion between frames, more than two frames are needed to reliably detect the object. Our method is designed to detect the object(s) with minimum delay, i.e., frames after the object moves, constraining the false alarms. Experiments on a new extensive dataset for moving object detection show that our method achieves less delay for all false alarm constraints than existing state-of-the-art.
