Smart cities: analytics, bigdata, cheap IoT sensors
Analytics, big data, cheap IoT sensors and other new #tech will help create smart cities and reduce air pollution. Shown here is Shanghai as seen from the bund (We originally used this photo in our much longer article about pollution in China, but the photo itself drew a lot of reader interest here and on social media). The haze over the city is due to PM2.5 particulate air pollution, which NASA estimates kills over 2 million annually. PM2.5 pollution levels in Shanghai are frequently in what the US EPA would consider the “unhealthy” range, at which 24 hour exposure can impact cancer statistics according to WHO information. Today, citizen scientists can purchase inexpensive arduino-based iot devices to help them monitor indoor and outdoor pollution levels (Wikipedia link). Analytics on the data can help inform policies to help mitigate the pollution, as well as help residents take steps to stay healthy.

Digital data preservation: The photo pictures the larger Buddha of Bamiyan as it was (1968) and as it is today (2008 photo) after it was destroyed in 2001 by the Taliban, supposedly on the orders of Bin Laden himself (according to one documentary). Built 1,500 years ago in the 6th century AD, the Buddhas were a UNESCO World Heritage Site, and the larger statue was 53m tall (174 feet), the largest #statue in the world. But thanks to big data (well, small data in 1968) it turns out the larger Buddha cannot be destroyed, for it has been digitally preserved forever. Long before the Taliban came to power, high-resolution photographs were taken from multiple camera positions. Half a century ago, way back in 1968, scientists already used the technique of photogrammetry to reconstruct a 3D contour plot by analyzing the data from the multiple photographs. With the computers of that day, a 3D model accurate to within 20 centimeters preserved the giant Buddha.… Read the restEbola: Can big data or semantic text help?
“Many problems” in this case Yes it can. We’ll get to to how big data or semantic meaning can help in a moment. First a few observations. As the Prof. Redlener, the NYT’s expert on disaster preparedness put it, “There are many, many problems that have been revealed by this single case.” This is a polite way for saying what at the Dallas hospital was a major screw-up that needlessly put lives in danger and unnecessarily forced additional people into a 21-day quarantine. We can talk about using semantic text technologies to prevent these kinds of hospital errors, or big data to improve traveler screening processes. At the end of the day, however, this is a type of error that the billing department at the Dallas hospital should have been able to catch. EbolaCare(TM) insurance “Where do we send this bill?” “Hmmm, address in Liberia. Looks like he has EbolaCare(TM), the national health plan of Liberia.”… Read the restAsk Acculation: fight illegal mining with citizen science IoT crowdsourcing in Amazon rainforest?
Indiegogo campaign to stop illegal mining threatening the Amazon Rainforest We were spammed yesterday with a Twitter question from @DavidRabanus asking if we could add the ability to detect mercury vapor to our app. If so, we could submit it, as an entry in this Indiegogo contest to reduce mercury pollution from illegal gold mining in the Amazon Rainforest (activist hashtag: #ImproveArtisanalMining). (Update: David Rabanus wrote to strongly imply the tweet wasn’t spam.) We’re suckers for a good cause, however, so we’ll answer the question. The question of using Internet of Things technology to allow citizen-science, crowdsourced monitoring of pollution from activities like fracking and mining have repeatedly come up, so it’s worth a blog entry (especially after we previously suggested using fracking to prevent earthquakes.) It’s not clear whether they are looking for a technical, economic, or political solution. The project itself seems open ended — it could be a process, or it could be some sort of technology.… Read the restRecent Comments
