Digital Twins For Warehouses
Posted by Shubham Ghosh Roy in categories: innovation, robotics/AI
The above considerations have to be carefully factored in while selecting the approach to model different subsystems and modules, hardware or physics-based twins in the digital twin.
Data recording and logging are crucial components of any digital twin project. This data not only serves as the basis for simulation and testing but also facilitates debugging, system optimization and performance analysis. Effective data recording strategies can also assist in the validation of model assumptions, further enhancing system accuracy and reliability.
Digital twins are not merely simulation tools; they represent a fundamental shift in the way we can plan, design, deploy and optimize robotic automation systems in warehouses. A well-designed digital twin, factoring in the aspects outlined in this article, empowers reliable, predictable and efficient order fulfillment, catalyzing innovation and progress in customer satisfaction.

Hear the melodic singing of a supermassive black hole in the Milky Way… that woke up 200 years ago
Posted by Paul Battista in category: cosmology
Scientists believe galactic musical sounds were emitted from the Milky Way’s supermassive black hole at the turn of the 19th century.
How much water a fish consumes really depends on how much salt is in its surrounding habitat. While fish do drink some water — salty or fresh, depending on their surroundings — through their mouths, they mostly absorb it through their skin and gills via osmosis.
“You’ve got to think of a fish as sort of a leaky boat in the water,” Tim Grabowski, a marine biologist at the University of Hawaii, told Live Science. “You constantly have a movement of either water or the salts that are in the water between the fish’s body and the external environment.”

“World’s largest wooden city” set to be built in Stockholm
Posted by Kelvin Dafiaghor in category: habitats
Scandinavian studios Henning Larsen and White Arkitekter are designing Stockholm Wood City, which will become the world’s largest mass-timber development and have the “serenity of a forest”.
Set to be built in the Stockholm neighbourhood of Sickla, the project was dubbed the “world’s largest wooden city” by developer Atrium Ljungberg as it will use more timber that any other project in development.
Stockholm Wood City, which will have 7,000 office spaces and 2,000 homes and cover 250,000 square metres, is being designed by Danish studio Henning Larsen and Swedish firm White Arkitekter.

Photonic Quantum Computer Claims Speedup “Advantage”
Posted by Quinn Sena in categories: quantum physics, space, supercomputing
O.o!!!! Year 2022
A new photonic quantum computer takes just 36 microseconds to perform a task that would take a conventional supercomputer more than 9,000 years to complete. The new device, named Borealis, is the first quantum computer from a startup to display such “quantum advantage” over regular computers. Borealis is also the first machine capable of quantum advantage to be made available to the public over the cloud.
Quantum computers can theoretically achieve a quantum advantage that enables them to find the answers to problems no classical computers could ever solve. The more components known as qubits that a quantum computer has, the greater its computational power can grow, in an exponential fashion.

Apple Releases First Ever visionOS Beta
Posted by Shailesh Prasad in category: futurism
Apple today introduced the first version of the visionOS software, debuting the visionOS 1.0 Developer Beta. The introduction of the beta comes as Apple has announced the launch of the visionOS software development kit (SDK) that will allow third-party developers to build apps for the Vision Pro headset.
The SDK can be accessed through Xcode 15 beta 2, and while developers do not have access to the Vision Pro headset itself as of yet, Apple will begin allowing testing starting next month.

Discovery of novel primitive xeno nucleic acids as alternative genetic polymers adds piece to origin of life puzzle
Posted by Shailesh Prasad in categories: chemistry, genetics
The chemical origin of life on Earth is a puzzle that scientists have been trying to piece together for decades. Many hypotheses have been proposed to explain how life came to be and what chemical and environmental factors on early Earth could have led to it. A step required in a number of these hypotheses involves the abiotic synthesis of genetic polymers—materials made up of a sequence of repeating chemical units with the ability to store and pass down information through base-pairing interactions.
One such hypothesis is the RNA (ribonucleic acid) world hypothesis, which draws from this concept and suggests that RNA could have been the original biopolymer of life both for genetic information storage and transmission, and for catalysis. However, in the absence of chemical activation of RNA monomers, studies have found that RNA polymerization would have been inefficient under primitive dry-down conditions without specialized circumstances such as lipid or salt-assisted synthesis or mineral templating.
While this does not necessarily make the RNA world hypothesis less plausible, primitive chemical systems were quite diverse and could not have possibly been as clean to just contain RNA and lipids, suggesting that other forms of primitive nucleic acid polymerization may have also taken place.
