Physics AI od Siemens: gdzie kończy się autonomia maszyny

slawek•

Siemens twierdzi, że jego oprogramowanie Simcenter PhysicsAI przyspiesza symulacje inżynierskie nawet 1000 razy w porównaniu z tradycyjnymi solverami fizycznymi — i to nie jest liczba wzięta z sufitu, lecz wynik udokumentowanych wdrożeń przemysłowych. Co jednak zaskakuje bardziej niż sama prędkość, to fakt, że producent technologii otwarcie mówi, gdzie jego narzędzie nie może być używane: przy certyfikacji komponentów krytycznych dla bezpieczeństwa ludzkiego życia. W branży, która od dwóch lat ekscytuje się możliwościami AI, taka szczerość brzmi niemal rewolucyjnie. Co to jest Physics AI i jak różni się od klasycznej symulacji? Physics AI to kategoria oprogramowania inżynierskiego, które zamiast obliczać fizykę zjawiska od podstaw przy każdym uruchomieniu, uczy się przewidywać wyniki symulacji na podstawie historycznych danych treningowych. Efektem jest tak zwany model zastępczy (ang. surrogate model) — uproszczona reprezentacja zachowania fizycznego układu, zdolna do generowania prognoz w sekundy zamiast godzin. Tradycyjne narzędzia symulacyjne, takie jak solver fizyczny (ang. physics-based solver), rozwiązują równania różniczkowe opisujące rzeczywiste zjawiska — przepływ cieczy, naprężenia mechaniczne, termodynamikę — dla każdej nowej geometrii osobno. Symulacja jednego wariantu konstrukcji może trwać od minut do wielu godzin, w zależności od złożoności modelu. Simcenter PhysicsAI, rozwijany przez Siemens Digital Industries Software, należy do klasy narzędzi opartych na geometrycznym głębokim uczeniu (ang.…

Wideo tygodnia z teleskopu Hubble
This video showcases three insights of the most detailed mid-infrared view yet of the field that hosts the highly evolved star IRS 3, which is located just 0.55 light-years from Sagittarius A*, the Milky Way galaxy's central supermassive black hole. This first image shown includes data from Webb's NIRCam (Near Infrared Camera) and MIRI (Mid Infrared Instrument). The second video features only NIRcam data, while the third image uses only MIRI data. More information and download options: http://esawebb.org/videos/weic2617b/ Credit: ESA/Webb, NASA & CSA, P.

The James Webb Space Telescope’s NIRCam (Near Infrared Camera) and MIRI (Mid Infrared Instrument) instruments recently imaged planetary nebula NGC 2392, which is nicknamed the Lion Nebula due to its distinct shape. This near- and mid-infrared composite image reveals the complex structure of the nebula, which has formed and continues to be sculpted by the remains of a dying star. The stellar core, also known as a white dwarf, is located at the centre and looks like the button nose of the lion.

Transition video: Lion Nebula
The James Webb Space Telescope observed planetary nebula NGC 2392 with its MIRI (Mid Infrared Instrument) instrument, revealing the presence of dust and its varying structures within this tumultuous environment. Nicknamed the Lion Nebula due to its appearance, this collection of gas and dust is created and sculpted by the remains of a dying star, which is in the centre and resembles the button nose of the lion.

In these new images from the NASA/ESA/CSA James Webb Space Telescope to celebrate its fourth science anniversary, a familiar galaxy transforms into something far richer, and far more complex, than ever seen before. Webb’s unprecedented sensitivity across near- and mid-infrared wavelengths cuts through the thick lanes of dust that obscure Centaurus A’s centre in visible light, showing a densely packed tapestry of individual stars and an active, everchanging galaxy. These images mark four years of better-than-anticipated performance and successful science operations for the most powerful space telescope in history.

Pan video: Centaurus A
This video takes the viewer on a journey through space to the nearby galaxy Centaurus A, exposing the dusty structures and hidden activity that shape this unusual system. At the heart of the galaxy, an actively feeding supermassive black hole shines brightly, surrounded by complex structures sculpted by a past galactic collision and ongoing activity.
