The mortar resists microcracking through in situ crystallization of platy strätlingite, a durable calcium-alumino-silicate mineral that reinforces interfacial zones and the cementitious matrix. The dense intergrowths of the platy crystals obstruct crack propagation and preserve cohesion at the micron scale, which in turn enables the concrete to maintain its chemical resilience and structural integrity in a seismically active environment at the millennial scale. — Berkeley Lab
These sorts of structural deformations are not new — researchers have already demonstrated “memory” and “smart material” properties. One of the most popular technologies is known as shape memory alloy, where a change of temperature triggers a shape change. Other successful approaches use electroactive polymers, pressurised fluids or gasses, chemical stimulus and even in response to light. — kurzweilai.net
A Hyperloop in California could be built within a decade, for between $7 and $16 billion and there are no technical showstoppers, Ahlborn says.
In other words, while Musk’s initial estimate of $4 billion was somewhat optimistic, it wasn’t exceptionally far off, especially given that Ahlborn believes the ultimate number for the hyperloop between San Francisco and Los Angeles would come in toward the lower end of the range. — forbes.com
While independent communications infrastructure, renewable energy, and resilient heating and power systems may all be major priorities in contemporary urban development, the three aren’t typically incorporated into the same project. Beyond The Grid — an ambitious plan underway in the Two Bridges neighborhood of Lower Manhattan — does just that. And the fact that the proposal has been created in this neighborhood is no accident. — urbanomnibus.net
[...] Argonne scientists are taking on a challenge not usually associated with sophisticated computing: urban design. They say that for such large-scale developments, expert opinions, or even standard modeling, will no longer do. Instead, we need detailed simulations that will integrate immense amounts of data into one framework and project different scenarios for the designers to consider. Their initial prototype, called LakeSim, focuses on Chicago Lakeside. — nextcity.org
According to the terms of the proposed draft order, every taxi in Los Angeles would have to become accessible via a mobile application similar to the ones used by Uber and Lyft. These applications will require certification by the Taxi Commission, which can then specify things like pricing maximums and limits on hours worked in a single shift, and can perhaps even set up a rating and complaint system for passengers. — the New Yorker
On a recent visit to Mountain View, I got a peek at how the Google Maps team assembles their maps and refines them with a combination of algorithms and meticulous manual labor—an effort they call Ground Truth. The project launched in 2008, but it was mostly kept under wraps until just a couple years ago. It continues to grow, now covering 51 countries, and algorithms are playing a bigger role in extracting information from satellite, aerial, and Street View imagery. — wired.com
The suit charges that Google and senior executives stole Eli Attia's invention, which is a technology that shortens and makes significantly cheaper the design and construction process, mainly for high-rise and large buildings. Google estimates that the invention has potential revenue of $120 billion annually. — globes.co.il
Google announced today it’s making a platform available to museums that enables them to build mobile applications that take advantage of Google technology, including Street View and YouTube, to bring their exhibits to anyone with a smartphone. Through partnerships between museums worldwide and the Google Cultural Institute, there are now 11 museums and cultural institutions that have participated in this pilot project to date; their apps are live now on Google Play. — techcrunch.com
Of all the roles of government, emergency response may be the least controversial. When disaster hits, we expect our fire, police, and other public services to provide immediate relief. But as James McConnell, Assistant Commissioner for Strategic Data at the New York City Office of Emergency Management (OEM), reminds us, tactical effectiveness in a crisis requires more than boots on the ground, ready at a moment’s notice. — urbanomnibus.net
Los Angeles Mayor Eric Garcetti on Monday proposed the most ambitious seismic safety regulations in California history that would require owners to retrofit thousands of building most at risk of collapse during a major earthquake.
Garcetti’s recommendations target two of the riskiest types of buildings in Los Angeles built before 1980: concrete buildings and wooden structures built atop weak first floors, such as those on top of carports and garages and supported by slender columns. — LA Times
Beth Mosenthal penned an Op-Ed: Response to Michael Kimmelman's Critique of 1 WTC. She writes "I can only imagine the list of priorities that 1 World Trade entailed, but am still celebratory of the feat that it was realized despite perhaps the greatest obstacles any project could possibly...
Many of us who have ridden inside an elevator since its invention 160 years ago are accustomed to hearing its ominous hums and creaks, as well as stories of malfunctioning elevators that cause people to be stuck inside for hours. So, the idea of hopping into a cable-free elevator in a mid to...
Tate Worlds are exciting Minecraft ‘maps’ that present virtual environments inspired by artworks from Tate’s collection. The maps allow players of Minecraft to explore a range of paintings and sculpture, undertaking various activities and challenges that relate to the themes of the artworks, or exploring how they were made. Tate has teamed up with some of Minecraft’s best known mapmakers to create these virtual artworks, offering a unique combination of art, history and adventure. — Tate.org
The first two maps were released by the museum on November 24th and were based on two famous paintings of urban settings: Andre Derain’s 1906 painting of London, The Pool of London, and Christopher Nevinson’s 1920 painting of New York, Soul of the Soulless City.André Derain, the...
The video shows 15 different variations of one computational growth process. Based on this process we created a series of 3D printed wearables in cooperation with Prof. Neri Oxman from the MIT Media Lab.
