Sztuczna Inteligencja

AI i cyfrowe bliźniaki kontrolują jakość oliwy z oliwek

slawek•

Trzy technologie – sztuczna inteligencja, cyfrowe bliźniaki i spektroskopia – właśnie połączyły siły, by rozwiązać problem, który od lat nękał producentów oliwy z oliwek: jak sprawdzić jakość produktu bez niszczenia próbek. To podejście odwraca logikę tradycyjnej kontroli jakości, w której badanie zawsze oznaczało ingerencję w produkt. Dla branży spożywczej może to być równie przełomowe co przejście od ręcznego sortowania do automatycznych linii produkcyjnych. Trzy technologie, jeden problem: fałszowanie oliwy Oliwa z oliwek należy do najczęściej fałszowanych produktów spożywczych na świecie – rozcieńczanie jej tańszymi olejami, błędne oznaczanie klas jakości czy podrabianie oznaczeń geograficznych to zjawiska dobrze udokumentowane przez organy regulacyjne. Tradycyjne metody weryfikacji, oparte na chemicznej analizie próbek, są czasochłonne, kosztowne i – co kluczowe – wymagają pobrania i zniszczenia fragmentu badanej partii towaru. Nowe podejście opisane przez Bioengineer.org łączy spektroskopię bliskiej podczerwieni (NIR – Near-Infrared Spectroscopy) z modelami uczenia maszynowego i cyfrowymi bliźniakami, tworząc system zdolny do oceny jakości bez jakiejkolwiek ingerencji fizycznej w produkt. Spektroskopia NIR analizuje, jak próbka pochłania światło w zakresie bliskiej podczerwieni, a unikalne wzorce absorpcji ujawniają skład chemiczny oleju. Czym jest cyfrowy bliźniak w kontroli jakości żywności? Cyfrowy bliźniak to wirtualna replika fizycznego obiektu lub procesu, aktualizowana w czasie rzeczywistym na podstawie danych z…

Wideo tygodnia z teleskopu Hubble
The NASA/ESA Hubble and the NASA/ESA/CSA James Webb Space Telescopes recently stared at an eerie star-forming scene within the Carina Nebula, a massive gas and dust cloud located approximately 7,500 light-years away from Earth. The two telescopes offer complementary views of the shadowy form, nicknamed the Cat’s Head Nebula, which reflects the “magical” process of star formation. Hubble’s visible-light view shows the cat as a dark, elongated dust pillar and hints of young forming stars, while Webb’s infrared-light imagery unveils many stars and other hidden details.

Space Sparks episode 32: Stars brewing in a nebulous cauldron
In this Picture of the Month from the NASA/ESA James Webb Space Telescope, we visit a turbulent cauldron of star formation to see what is brewing inside dense clumps of gas. This is a star-forming region named LHA 120-N 159, or simply N159, located 161 000 light-years away in the Large Magellanic Cloud (LMC), one of the satellite galaxies orbiting the Milky Way galaxy. This image spans about 230 light years across. Learn more about this image here.

A technicolor dreamscape is revealed in this new image from the NASA/ESA/CSA James Webb Space Telescope. It portrays a stellar nursery known as NGC 7129, a nebula that holds numerous protostars and stars within its fields of gas and dust. Webb captured infrared light, which pierces through the dense matter that scatters or absorbs other types of light. This region, rife with stellar objects in different stages of their lives, offers an opportunity to explore how stars shape their surrounding environment.

This NASA/ESA/CSA James Webb Space Telescope Picture of the Month features galaxies in incredible detail that have been warped and multiplied like they’ve stepped into a house of mirrors. The brilliant golden galaxies splashed across this image belong to a galaxy cluster called MACS J0454.1-0300. MACS J0454.1-0300 is itself incredibly distant: the light from these galaxies has been travelling to us for so long that we’re seeing the cluster as it was when the Universe was about 8 billion years old. The orange galaxies concentrated on one side of the cluster are not actually part of the cluster; these galaxies are much farther away from us than the galaxies that make up MACS J0454.1-0300.
