If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."
However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …
Today's urban life is out of imagination without the presence of elevators and the elevator controller algorithm has been well studied by different techniques including reinforcement learning . A glance over the references gave the impression that the majority of studies has focused on elevators installed in high-rise buildings while those in train stations are barely discussed. Elevators in train stations, however, deserve their own attention because of their obvious difference from systems in buildings. A good example is the Gare de Lyon in Paris, a station with 2 underground floors on which you find 2 different train lines' platforms respectively. From my personal experience, it usually takes quite a while to get to floor -2 from floor -1 for a train change with my baby stroller by elevator.
On the evening of Oct. 31, 25-year-old Fukuoka native Kyota Hattori -- wearing makeup and a purple and green ensemble to emulate the villainous Joker of "Batman" franchise fame -- boarded a Keio Line train at Keio-Hachioji Station, heading for central Tokyo. After spending half an hour meandering around Shibuya, which was packed with costumed revelers feting Halloween, Hattori headed back toward Hachioji, but reversed direction again at Chofu, where he changed to a Shinjuku-bound limited express train. Soon after the doors closed, according to eye witness reports, he removed a survival knife and liquids from a backpack. When a 72-year-old male passenger tried to intervene, Hattori allegedly stabbed the man and proceeded to pursue fleeing passengers, splashing them with lighter fluid, which he then ignited. The stabbing victim was hospitalized in a critical condition and 16 other passengers suffered burns and smoke inhalation.
Niigata – East Japan Railway Co. on Wednesday invited the media to observe a test run of an autonomous bullet train in Niigata Prefecture as it eyes introducing trains without drivers in the future amid a labor shortage. During the test, conducted in the early hours of Wednesday, the 12-car bullet train ran without any manual intervention after a driver switched it to automatic mode. The E7-series train was piloted remotely from a control center. It was the first test in Japan of the autonomous operation of a bullet train already in commercial service. While the eventual goal is driverless trains, several drivers and other staff members were aboard the train during Wednesday's test to respond to any emergencies.
The internet of things (IoT) can help prevent crime and ensure public safety. The need for gathering and processing large volumes of data makes the application of IoT in the public sector highly impactful. Governments have the responsibility of ensuring the health, safety, and prosperity of large populations, with the help of an incredibly small supply of personnel. This makes the use of IoT in enabling government functions obvious. Using IoT in the government sector can ensure the smooth functioning of routine activities and focus on long-term, demanding projects.
Artificial intelligence (AI) is shedding light on one of the most examined yet least understood experiences of modern life: the customer journey. From shopping malls and sports arenas, to train stations and city streets, C2RO is an AI-powered video analytics platform that captures anonymized data about people's movement so organizations can improve the customer experience. "We analyze human behaviour in physical spaces, and transfer it into actionable data," said Tim Heaney, vice president of sales at C2RO. "With a fact-based understanding of the amount of people coming into a space, how they move through it with whom, where they linger, and what they touch and eventually purchase, organizations can manage physical environments more efficiently to improve the customer experience and business results." A transportation organization used data from C2RO to improve subway train and bus terminal planning. "Based on the number of people boarding and leaving trains at certain times and days, as well as which direction they're headed at terminals, transportation managers could alleviate traffic crunches," said Heaney.
Siemens and German rail operator Deutsche Bahn (DB) revealed on Monday, October 11, the world's first driverless, fully automated train in the city of Hamburg. Richard Lutz, CEO of DB said, "with automated rail operations, we can offer our passengers a significantly expanded, more reliable and therefore improved service -- without having to lay a single kilometer of new track." Though several airports around the world have driverless monorail terminal shuttles and Paris has driverless metro trains, the new train by Siemens and Deutsche Bahn is the first fully automated train that can safely run on existing rail infrastructure alongside regular human-driven trains. In its statement, Siemens describes the new train as more efficient due to the use of artificial intelligence (AI), which helps the train stick to schedule and meet increased travel demand more efficiently than a human driver. Four of the trains will go into operation in northern Hamburg's S-Bahn rapid urban rail network and they will start carrying passengers in December.
Or maybe you're wondering why we should even care about trains and how they operate--what is this, the 1800s?--so let's back up a bit. If you think America is solely dependent on trucks to move freight, you might be suffering from tunnel vision: Trains account for a third of the ton-miles--that is, a ton of weight carried a mile--that freight travels in the U.S. every year. That's almost as much as is carried by trucks. The U.S. has the most extensive rail network of any country on earth by miles of track--yes, even bigger than China's--and it's currently facing some of the same snarls and congestion as seemingly every other part of the country's supply chains, on account of unprecedented activity at ports and record demand at some rail hubs. Trains might seem like a mature technology with little room for improvement or expansion, since adding new rail lines is prohibitively expensive, as battles over the cost of the expansion of Amtrak service have shown.
The proportion of railway equipment and technologies companies hiring for artificial intelligence related positions rose in August 2021, with 29.7% of the companies included in our analysis recruiting for at least one such position. This latest figure was higher than the 24.6% of companies who were hiring for artificial intelligence related jobs in July 2021 and an increase compared to the figure of 23.5% for the equivalent month last year. When it came to the proportion of all job openings that were linked to artificial intelligence, related job postings dropped in August 2021, with 0.8% of newly posted job advertisements being linked to the topic. This latest figure was an increase compared to the 0.7% of newly advertised jobs that were linked to artificial intelligence in the equivlent month a year ago. Artificial intelligence is one of the topics that GlobalData, from whom our data for this article is taken, have identified as being a key disruptive force facing companies in the coming years.
East Japan Railway Co. has suspended the addition of released prisoners to its list of people tracked at its train stations by security cameras using facial recognition technology, after it started the practice this summer, it was learned Wednesday. JR East suspended the tracking due to concerns over invasions of privacy from outside the company, company officials said. According to JR East, the cameras were set up at its stations in July as part of strengthened security for the Tokyo Olympics and Paralympics. Those subject to JR East's tracking were suspicious people wandering around stations, wanted suspects and released prisoners and parolees who had committed serious crimes at the company's stations and inside its trains. JR East received information on the discharged prisoners and others from the Public Prosecutors Office under a system that notifies victims and managers of places where a crime occurred of a perpetrator's release from prison. After obtaining such information, the company was going to consider whether to register their face photos on its database.
With a total of 67,956 kilometers of railways in 2020 India ranked 4th just behind the United States, China and Russia. While Indian Railways, a statutory body under the Indian Ministry of Railways, manages one of the world's largest rail networks, adjusting for the size of the country reveals that a much smaller portion of the territory is covered in railroads. Using the 2019 official subdistrict boundary data generously provided by superb GIS specialist Justin Elliot Meyers on his rich GitHub page as well as Geofabrik OpenStreetMap data for India, we'll learn how to effortlessly compute the length of railways and land area size for every Indian subdistrict polygon to arrive at railway density, measured as 1 kilometer of railway per 100 square kilometers of land area. And we'll do it programatically in R using 150 lines of code. Once you go through the code, you'll be able to apply it to other spatial lines such as roads or rivers.
