How To Reinvent Continuous Improvement With Intelligent Digital Twins In Manufacturing

The Industrial Internet of Things (IIoT) connects IoT with Industry. The IIoT allows companies to reap information from their machines and environments to create intelligent, self-learning machines. This interconnected ecosystem provides numerous benefits for enterprises, such as reduced downtime, increased throughput and safety, and predictive maintenance — leading to greater efficiency. The 4th Industrial Revolution is fueled by exponential advancements in digital technology and brings us closer to a sustainable future of intelligent manufacturing environments that operate with zero emissions. With the advent of Industry 4.0, there has been a massive increase in the levels of data being produced by intelligent machines. This enormous increase in information can be hard to manage and analyze effectively without converting into usable insights. These insights are gained through the use of various technologies, including intelligent digital twins that allow for real-time monitoring of a machine’s condition, AI that can analyze large amounts of data to produce actionable insights, and connected devices that provide live status updates.

Building The Metaverse

The talk about metaverse really went ballistic after Facebook changed its corporate name to Meta and CEO Mark Zuckerberg’s keynote at the Facebook Connect event touted the metaverse as the social networking future. But most of the talk is not really about the true metaverse as envisioned in science fiction and first described in in Neal Stephenson’s 1992 cyberpunk science fiction novel Snow Crash. A true metaverse needs to be an interconnected “Internet” of virtual spaces that are open to many different companies, not a walled garden. It will take an open platform offering access to a shared virtual space to create the true metaverse. And it will also require a level of standardization and interoperability that doesn’t exist today.

In Snow Crash, the Metaverse was a phrase coined by as a successor to the Internet. It was a vision of how a virtual-reality-based Internet might evolve and was heavily influenced by early video games. This version of the metaverse resembles a persistent massive multiplayer online game (MMO). Players would have user-controlled avatars, and there were a social hierarchy, but there was pervasive access and a global scale.

The closest we came to open 3D interoperability was VRML (Virtual Reality Markup Language) back in the 1990s. The HTML approach to creating a metaverse using the VRML standard attempted to create a virtual 3D markup language that could be used to create and link 3D spaces together into one that you could access through a VRML browser. It failed.

AI And Optimism: Jim Mellon Wants Us All To Live Longer

There is nothing inevitable about aging, or about its rate. Californian bristlecone pines are believed to live for 5,000 years, and there are long-lived mammalian creatures as well. Some marine creatures do not display any signs of aging at all, including hydra, jellyfish, planarian worms, and coral. Certain human cells have immortal characteristics too. When a woman gives birth, she produces a baby which is “new”. Her “germline” (reproduction-related) cells produce a child with no signs of age.

These and many other considerations combine with the unreasonable effectiveness of modern AI to lead some people to believe that significant advances in longevity are imminent. These advances probably cannot happen without the active participation of the wider pharmaceutical industry, and the acceptance by policy makers and regulators that aging is a disease, not just an unfortunate and inevitable component of the human condition. There is still considerable reluctance among major pharmaceutical companies to contemplate specific anti-aging therapeutic developments. But there are encouraging signs of this reluctance being challenged, especially at Novartis and AstraZeneca.

Beyond the pharma giants, Mellon reckons there are 255 companies which claim to be specifically targeting aging, of which 35 are listed on stock markets. But he thinks that only a minority of them are genuinely working to tackle aging, as opposed to one of the diseases it causes, like cancer, dementia, or heart disease. He likens the state of the longevity industry today to the internet industry of 20 years ago, when it was still in its dial-up phase, and downloading information (or, heaven forbid, images) was like sucking jelly through a straw. And although longevity will have such a massive impact on all of us that you might expect progress to be expedited, Mellon points out that the internet did not have to go through lengthy and expensive FDA trials at every step.

Multi-gigabit fiber internet launched in Reno (updated)

Telecom provider AT&T this week said some local customers now have access to faster internet with the addition of 2 gigabit and 5 gigabit fiber internet to the community. Reno is one of more than 70 metro regions in the country to get the upgrade.

The top speeds for AT&T fiber internet had previously been 1 gig.

AT&T officials said the rollout of the improved fiber network for residential customers was in response to pandemic shifts in how people work, with many more people setting up home offices or making their homes a permanent workplace.

Meta Is Making a Monster AI Supercomputer for the Metaverse

Though Meta didn’t give numbers on RSC’s current top speed, in terms of raw processing power it appears comparable to the Perlmutter supercomputer, ranked fifth fastest in the world. At the moment, RSC runs on 6,800 NVIDIA A100 graphics processing units (GPUs), a specialized chip once limited to gaming but now used more widely, especially in AI. Already, the machine is processing computer vision workflows 20 times faster and large language models (like, GPT-3) 3 times faster. The more quickly a company can train models, the more it can complete and further improve in any given year.

In addition to pure speed, RSC will give Meta the ability to train algorithms on its massive hoard of user data. In a blog post, the company said that they previously trained AI on public, open-source datasets, but RSC will use real-world, user-generated data from Meta’s production servers. This detail may make more than a few people blanch, given the numerous privacy and security controversies Meta has faced in recent years. In the post, the company took pains to note the data will be carefully anonymized and encrypted end-to-end. And, they said, RSC won’t have any direct connection to the larger internet.

To accommodate Meta’s enormous training data sets and further increase training speed, the installation will grow to include 16,000 GPUs and an exabyte of storage—equivalent to 36,000 years of high-quality video—later this year. Once complete, Meta says RSC will serve training data at 16 terabytes per second and operate at a top speed of 5 exaflops.

SpaceX’s Starship Will Be Capable Of Capturing Satellites To Be Repaired In Orbit Or Returned To Earth

SpaceX’s Starship will be a multipurpose launch vehicle, capable of returning astronauts to the Moon to build a permanent base and enabling humanity to build a sustainable colony on Mars. It is expected to become the world’s most powerful rocket-ship. “Starship was designed from the onset to be able to carry more than 100 tons of cargo to Mars and the Moon. The cargo version can also be used for rapid point-to-point Earth transport. Various payload bay configurations are available and allow for fully autonomous deployment of cargo to Earth, Lunar, or Martian surfaces,” the company said.

SpaceX’s Starship launch vehicle has many potential uses and capabilities that will enable access to space like never before. The cargo version of Starship will be able to launch entire satellite constellations in a single launch inside its payload bay. For perspective, SpaceX’s Falcon 9 can carry up to 60 Starlink in a tight configuration inside its 5.2-meter diameter fairing, Starship will be able to carry 400 Starlink to deploy in a single launch inside its fairing. Starship will be capable of deploying giant spacecraft to space inside its clamshell-like fairing, which has an outer diameter of 9-meters –“the largest usable payload volume of any current or in development launcher,” the company says. SpaceX also plans to design an extended Starship volume capability for payloads requiring up to 22-meters of height.

Starship will also be able to capture already in orbit to be repaired or brought back to be disposed of on Earth, according to SpaceX’s Starship User Guide. “Fully-reusable Starship and Super Heavy systems are expected to allow for space-based activities that have not been possible since the retirement of the Space Shuttle and Space Transportation System, or have never been possible before. With a fully reusable Starship, can be captured and repaired in Orbit, returned to Earth, or transferred to a new operational orbit,” SpaceX’s vehicle guide says. This will be possible with Starship’s large clamshell-like cargo door mechanism that opens and closes, as shown in the image below. The clamshell door can be modified to “chomp up” old and space junk orbiting Earth. “We can fly Starship around space and chomp up debris with the moving fairing door,” SpaceX founder Elon Musk said in July 2021.

Twin-field quantum key distribution (QKD) across an 830-km fibre

By using quantum key distribution (QKD), quantum cryptographers can share information via theoretic secure keys between remote peers through physics-based protocols. The laws of quantum physics dictate that photons carrying signals cannot be amplified or relayed through classical optical methods to maintain quantum security. The resulting transmission loss of the channel can limit its achievable distance to form a huge barrier to build large-scale quantum secure networks. In a new report now published in Nature Photonics, Shuang Wang and a research team in quantum information, cryptology and quantum physics in China developed an experimental QKD system to tolerate a channel loss beyond 140 dB across a secure distance of 833.8 km to set a new record for fiber-based quantum key distribution. Using the optimized four-phase twin-field protocol and high quality setup, they achieved secure key rates that were more than two orders of magnitude greater than previous records across similar distances. The results form a breakthrough to build reliable and terrestrial quantum networks across a scale of 1,000 km.

Quantum cryptography and twin-field quantum key distribution (QKD)

Quantum key distribution is based on fundamental laws of physics to distribute secret bits for information-theoretic secure communication, regardless of the unlimited computational power of a potential eavesdropper. The process has attracted widespread attention in the past three decades relative to the development of a global quantum internet, and matured to real-world deployment through optical-fiber networks. Despite this, wider applications of QKD are limited due to channel loss, limiting increase in the key rate and range of QKD. For example, photons are carriers of quantum keys in a QKD setup, and they can be prepared at the single-photon level to be scattered and absorbed by the transmission channel. The photons, however, cannot be amplified, and therefore the receiver can only detect them with very low probability. When transmitted via a direct fiber-based link from the transmitter to the receiver, the key rate can therefore decrease with transmission distance.

Google warns that defamation case ruling will force it to ‘censor’ the internet

The Guardian reports that the case revolves around George Defteros, a Victoria defense lawyer who previously represented Melbourne gangland figures. He sued Google over claims that its publication of search results showing a 2004 article defamed him.

The article from The Age implied that Defteros had become more than just a lawyer for criminal elements but was also a friend and confidant, crossing professional boundaries. The piece also reported on the murder charges Defteros faced in relation to the killing of three men. Prosecutors withdrew the charges in 2005.

Defteros’ lawyers contacted Google in February 2016 and asked it to remove the article, but Google refused as it said The Age was a reputable source. The piece was eventually removed in December 2016 after it had been accessed a further 150 times.

Facebook robot winds fiber-optic cable around power lines

A Facebook robot that wraps fiber-optic cable around existing power lines could help bridge the digital divide by bringing internet access to some of the billions of people who currently lack it.

Why it matters: The 60% of the world population with internet access has social, economic, financial, and educational advantages over the other 40%, most of whom live in developing nations or rural areas.

The cost of expanding internet networks is a major barrier to bringing internet access to those people — if the Facebook robot can cut that cost, it could help close this “digital divide” and make the world a more equitable place.

Why User Education Is Necessary To Avoid AI Failure

The more a technology or concept permeates and gets normalized in our day-to-day lives, the more we grow to expect from it. About two decades ago, a sub-56kpbs dial-up internet connection seemed miraculous. Today, with internet speeds as high as 2000Mbps becoming normal, the 56Kbps connection would be considered a failure of sorts—in the developed world, at least. This shift in expectation also applies to AI. Having seen numerous practical AI applications aid human convenience and progress, both the general population and the AI research community now expects every new breakthrough in the field to be more earth-shattering than the previous one. Similarly, what qualifies as AI failure has also seen a massive shift in recent years, especially from a problem owner’s perspective. failure, in most cases, is attributed to technology-centric factors like the quality of data or the capabilities of algorithms and hardware used, ignoring the most crucial aspect of AI success—the end user.
