What Are Smart Cities (And Why Should We Care)?

#artificialintelligence

You can be forgiven if your first reaction to hearing the term "smart cities" is an eye roll. Sure, we have smart diapers, smart toothbrushes and smart faucets, but cities? How is that even possible? While the word is a bit amorphous, there's no question that smart cities are a thing and an important one at that. Cities are the locus of much of the world's population and economic activity. By 2050, a full 66 percent of the world is expected to reside in one, according to the United Nations.


Tech for Good: How machine learning and rich data can help prevent pollution

#artificialintelligence

As part of a regular series powered by IBM, BetaKit interviews Canadian tech leaders using innovation for the greater good. In the environmental tech space, common missions revolve around reducing pollution, fixing destroyed habitats, or making the environment better. Less commonly will you find a startup that wants the world to spend less money on solutions, but that's exactly what Ambience Data hopes to do. The company's internet-of-things (IoT) sensors provide hyperlocal air quality data and, through machine-learning algorithms on the cloud, aid in urban development strategy. Instead of trying to fix environmental problems, co-founder and CEO Nisha Sarveswaran hopes that Ambience Data can turn the conversation to investing in prevention.


Banking on Big Data -- Environmental Protection

#artificialintelligence

Sophisticated tools capable of collecting and analyzing massive data sets and then displaying the results in visual form are no longer an option. They are becoming a necessity. On a daily basis, thousands upon thousands of monitoring stations around the world collect vast quantities of air quality data for use in spotting pollution problems, analyzing air quality trends, and guiding effective responses. To date, these monitoring stations have served as digital eyes and ears trained on the planet's atmosphere. But all of that seems likely to change in the not-too-distant future as evolving networks of air sensors that are just now beginning to be deployed around the globe result in an avalanche of data, all of which has the very real potential to overwhelm those trying to make sense of it.


The algorithm that could end office thermostat war

Daily Mail

Researchers at Concordia University have designed a system that optimizes indoor environmental conditons including air quality, temperature and lighting based on the preferences of each office worker, while also optimizing energy consumption. Then, they created a mathematical model of the preferences of each office worker to simulate worker preferred indoor temperatures, ventilation rates, natural light and artificial lighting based on sensors places throughout the office.

Light: Science & Applications - Air quality monitoring using mobile microscopy and machine learning

#artificialintelligence

Rapid, accurate and high-throughput sizing and quantification of particulate matter (PM) in air is crucial for monitoring and improving air quality. Here we present a field-portable cost-effective platform for high-throughput quantification of particulate matter using computational lens-free microscopy and machine-learning. This mobile device rapidly screens 6.5 L of air in 30 s and generates microscopic images of the aerosols in air. We tested this mobile platform by measuring the air quality at different indoor and outdoor environments and measurement times, and compared our results to those of an Environmental Protection Agency–approved device based on beta-attenuation monitoring, which showed strong correlation to c-Air measurements.


Machine Learning Based Mobile Microscope Might Help Detect Air Quality Better

International Business Times

They have developed quite a unique mechanism to measure air quality for cheap -- a mobile microscope connected to a smartphone which will detect the air quality using a machine-learning algorithm. The aim of the invention is to provide users the ability to accurately assess dangerous airborne particulate matter and avoid health hazards, which kill 7 million people prematurely annually according to the World Health Organization. Accurate analysis of air quality is very important for improving this air quality and the researchers claim this device might be capable of such analysis. Cheaper air quality analysis might help create better air quality solutions.


A day in the life of a journalist in 2027: Reporting meets AI

#artificialintelligence

Here's what we came up with by extrapolating technology and journalism trends highlighted in AP's report: The sensors send an alert to his vehicle's smart dashboard: "There has been a 10 percent decrease in air quality in Springfield." He downloads images from a series of robotic cameras posted throughout the region and uses computer vision (an algorithm able to view and comprehend a photo or video with enhanced accuracy) to compare photos of the area around the factory over time. The representative, the journalist suspects, may be hiding something; voice analysis technology declares the tone of the person on the phone is "tentative" and "nervous." Sitting in his car on the way back to the newsroom, the journalist runs a voice recording of the interview through his sentiment analysis system, which determines the mother's tone to be "genuine" and "analytical."


Netgear Arlo Baby review: a better baby monitor

PCWorld

Beneath the kid-friendly kit are the robust features we've seen in Netgear's Arlo Q indoor security camera: 1080p full HD video, night vision, sound and motion detection, two-way audio, 24/7 recording, and free cloud storage. Lastly, a pair of sensors monitor indoor temperature, humidity, and air quality levels and alert you when they're out of range, so you can maintain an optimum nursery environment. Along the top of the streaming window are Wi-Fi, battery, and sound and motion alert indicators; access a to timeline for use with CVR plans; and a counter displaying how many unwatched video clips are in your library. Under the window are the camera controls: buttons for pausing the stream, recording video on demand, taking a snapshot of the live feed and toggling the mic and speaker on and off.


A breath of fresh data

#artificialintelligence

Inspired by the problem, Chiwewe got to work on a solution: an air quality forecasting platform, developed in collaboration with South Africa's Council for Scientific and Industrial Research, that's undergoing trials in Johannesburg. With an accurate understanding of pollution patterns, the city could identify –and prosecute – major polluters, plan the location of future roads and settlements, and tailor intervention strategies. While Beijing has a network of more than 30 air quality monitoring stations, and Johannesburg has eight, many African cities have no stations to measure air pollution at all. "We can combine satellite data, weather data and climate chemistry models using machine learning and AI," Chiwewe says.


Coway's Airmega integrates Alexa voice controls for its air filtration systems

#artificialintelligence

Coway makes Airmega air filtration systems that suck allergens out of the air in your home. And now it's making the devices easier to control, with the integration of Amazon Alexa voice commands, starting in mid-January. With Alexa, you can now ask Airmega for updates on indoor air quality, filter lifetime, fan speed changes, timer setup, and more. In its automated smart mode, Airmega quietly goes about filtering your air with a high-efficiency particulate air filter (HEPA).
