The ‘Add to profile grid’ feature comes in handy when you remove a reel from your Instagram profile or forget to share the reel to feed while posting. This was a long-requested feature, previously available in older versions of Instagram but was removed later. Watch Anitescu’s presentation here.UPDATE (November 17, 2022) – The latest 2022 version of Instagram for iPhone and Android finally brings the option to add reels back to profile grid. “The task before us is to use digital twins to convince the public, not just with words but with proof from simulations, that proposed plans for renewable energy will be as reliable as – or more reliable than – what we currently have,” Anitescu said. In the past decade the reliability of the power grid has actually decreased by a factor of 2. “Reliability is the biggest elephant in the room,” Anitescu said. But how can we be sure that the results will be reliable? In the latter part of his presentation Anitescu focused on this point, citing from several different articles expressing lack of confidence in current carbon-neutral plans. With Julia, then, researchers are likely to be able to build digital twins far more rapidly. Programmer productivity increased enormously,” Anitescu said. Moreover, the Julia code was only 6,000 lines instead of the original 100,000. ”The code, which had been 5 times slower on the GPU, now ran 8 times faster. “The results were extraordinary,” said Anitescu. Instead, Anitescu and his team had to completely rewrite the algorithm, using the language Julia rather than C++. The assumption was that the highly optimized ACOPF code would be significantly faster on GPUs. UsIng the example of the alternating-current optimal power flow ( ACOPF) problem – one of the most important optimization problems in electric power systems – he noted the desirability of exploiting graphic processing units (GPUs) for accelerated computing. In accordance with his background, Anitescu focused his talk on the computational aspects of digital twin technology. Participating in the workshop panel was Mihai Anitescu, a senior computational mathematician in the Mathematics and Computer Science division at Argonne and a professor of statistics at the University of Chicago. To answer this question, on July 26, 2023, the National Academies of Science, Engineering, and Medicine sponsored a workshop on Digital Twins for the Electricity System. And thus another question arises: “What problems must be solved in order to make an electricity grid-centered digital twin a reality?” goals of achieving near-zero decarbonization by 2050. Numerous industries are already exploring digital twin technology as a path forward toward meeting U.S. Thus, it can save developers time in testing and validating a product before it is released in the marketplace. Moreover, the digital twin has access to constantly updated data, which it can analyze and apply the results back to the original physical object. Unlike a traditional simulation, however, the digital twin can run multiple simulations. Sensors digitally capture the actual physical structure and create a model that then can be used to run simulations. Simply put, it is a virtual representation of a real-world physical object or system or environment.
