The world’s ugliest music | Scott Rickard | TEDxMIA
(0) | 16/02/2018 | Translate: Scott Rickard has degrees in Mathematics, Computer Science, and Electrical Engineering from M.I.T. and MA and PhD degrees in Applied and Computational Mathematics from Princeton University. At University College Dublin, he founded the Complex & Adaptive Systems Laboratory, where biologists, geologists, mathematicians, computer scientists, social scientists and economists work on problems which matter to people. He is passionate about mathematics, music and educating the next generation of scientists and mathematicians.
Read an ancient text written on a papyrus scroll without unrolling it Brent Seales, professor of computer science at the University of Kentucky, discusses his work, spanning two decades, rescuing ancient texts such as the charred scrolls of 'Herculaneum. - Phase-Functioned Neural Networks for Character Control We present a real-time character control mechanism using a novel neural network architecture called a Phase-Functioned Neural Network. In this network structure, the weights are computed via a cyclic function which uses the phase as an input. Along with the phase, our system takes as input user controls, the previous state of the character, the geometry of the scene, and automatically produces high quality motions that achieve the desired user control. The entire network is trained in an end-to-end fashion on a large dataset composed of locomotion such as walking, running, jumping, and climbing movements fitted into virtual environments. Our system can therefore automatically produce motions where the character adapts to different geometric environments such as walking and running over rough terrain, climbing over large rocks, jumping over obstacles, and crouching under low ceilings. Our network architecture produces higher quality results than time-series autoregressive models such as LSTMs as it deals explicitly with the latent variable of motion relating to the phase. Once trained, our system is also extremely fast and compact, requiring only milliseconds of execution time and a few megabytes of memory, even when trained on gigabytes of motion data. Our work is most appropriate for controlling characters in interactive scenes such as computer games and virtual reality systems.
- NASA & TRAPPIST-1: A Treasure Trove of Planets Found Seven Earth-sized planets have been observed by NASA's Spitzer Space Telescope around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of these planets are firmly in the habitable zone. Over 21 days, NASA's Spitzer Space Telescope measured the drop in light as each planet passed in front of the star. Spitzer was able to identify a total of seven rocky worlds, including three in the habitable zone, where liquid water might be found. The video features interviews with Sean Carey, manager of the Spitzer Science Center, Caltech/IPAC; Nikole Lewis, James Webb Space Telescope project scientist, Space Telescope Science Institute; and Michaël Gillon, principal investigator, TRAPPIST, University of Liege, Belgium. The system has been revealed through observations from NASA's Spitzer Space Telescope and the ground-based TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, as well as other ground-based observatories. The system was named for the TRAPPIST telescope.
- Sketchpad – CAD program in 1963 with a graphical user interface This video is a TV show made about the software Ivan Sutherland developed in his 1963 thesis at MIT's Lincoln Labs, "Sketchpad, A Man-Machine Graphical Communication System", described as one of the most influential computer programs ever written. This work was seminal in Human-Computer Interaction, Graphics and Graphical User Interfaces (GUIs), Computer Aided Design (CAD), and contraint/object-oriented programming. While watching this video, remember that the TX-2 computer (built circa 1958) on which the software ran was built from discrete transistors (not integrated circuits -it was room-sized) and contained just 64K of 36-bit words (~272k bytes).
- One day, a computer will fit on a desk (1974) Science fiction writer Arthur C. Clarke makes the bold claim that one day computers will allow people to work from home and access their banking records.
- An explanation of Moore’s law, modern computing, and why it’s difficult to make faster chips SciShow explains how SciShow exists -- and everything else that's ever been made or used on a computer -- by exploring how transistors work together in circuits to make all computing possible. Like all kinds of science, it has its limitations, but also awesome possibilities.
- One of the biggest computational fluid dynamics simulation made on a super computer This is one of the largest CFD simulations ever, on the world's largest GPU server, the GigaIO SuperNODE, equipped with 32x AMD Instinct MI210 64GB GPUs, for a total of 2TB of VRAM. The simulation shows the Concorde (62m long) before landing at a speed of 300km/h and an angle of attack of 10°, for 1 second in flight. The span-based Reynolds number is 146 million.

- Elan: The most violent school in history The Elan school for troubled kids was created in 1970 at Maine, United States, and was closed in 2011 mostly due to bad reputation after disclosures on Internet sites. The school was accused for psychological and physical torture, humiliation, sleep deprivation, poor nutrition, inability to escape or communicate with the outside world, sectarian structure with a system of hierarchy and ranks between the students.

- Οι δίδυμοι πύργοι σβήνονται από τις φωτογραφίες σε ντοκιμαντέρ του 1986 Στο απόσπασμα από το ντοκιμαντέρ "Dream Machine: The Visual Computer" του 1986 για τα ψηφιακά γραφικά υπολογιστών και το animation, γίνεται μια επίδειξη επεξεργασίας φωτογραφιών. Σε μία εξ αυτών, σβήνονται οι δίδυμοι πύργοι του World Trade Center από τις φωτογραφίες.
