If necessity really is the mother of invention, then surely the auto industry is on the verge of an era of blinding brilliance. Times are that bad.

In July, when the price of a barrel of oil shot up to US $147, buyers in the United States dumped their gas guzzlers and lined up for that iconic hybrid, the Toyota Prius. And, astonishingly, by year’s end they had bought 25 000 Smart ForTwo cars, two-seaters so small they make the Mini Cooper, with its lavish complement of four seats, look like a land yacht.

Shoppers are seeing more and more empty shelves, as stores around the world struggle to keep products stocked. The situation is the result of supply-chain issues caused in part by the COVID-19 pandemic. The product-unavailability rate increased from 5 percent to 15 percent during the past three years, according to the Consumer Brands Association.

To make it easier for stores to track inventory, startup Wisy developed an AI platform that uses image recognition to detect which products are out of stock or running low, as well as those that are available but haven’t yet been put on display.

When Gamers Get Nasty

Researchers grapple with subjectivity as they develop algorithms to detect toxicity in online gaming

Online gaming is a chance for players to come together, socialize, and enjoy some friendly competition. Unfortunately, this enjoyable activity can be hindered by abusive language and toxicity, negatively impacting the gaming experience and causing psychological harm. Gendered and racial toxicity, in particular, are all too common in online gaming.

To combat this issue, various groups of researchers have been developing artificial-intelligence models that can detect toxic behavior in real time as people play. One group recently developed a new such model, which is described in a study published 23 May in IEEE Transactions on Games. While the model can detect toxicity with a fair amount of accuracy, its development demonstrates just how challenging it can be to determine what is considered toxic—a subjective matter.

Fuel cell electric vehicles (FCEVs) often reach higher energy density and exhibit greater efficiency than battery EVs; however, they also have high manufacturing costs, limited service life, and relatively low power density.

Modeling and simulation can improve fuel cell design and optimize EV performance. Learn more in this white paper.
