Lift (or elevator) breakdowns cause huge inconveniences to city dwellers and affect more than 80% of Singapore’s residents who live in high-rise apartments. Unfortunately, lift maintenance today is either preventive (e.g., follows a fixed cycle based on statistics) or reactive (the faults are fixed after they happen).

As symptoms typically manifest over some time before a breakdown happens, with the Internet of Things (IoT), massive amounts of data can be reliably collected from lifts fitted with myriad sensors. By applying artificial intelligence (AI) technologies to these data, along with operational data, such as fault records collected when a breakdown happens, predictive lift maintenance is now possible, empowering technicians to fix the lifts before they break down.

University Blockchain Research Initiative (UBRI): Boosting blockchain education and research.

Since its conceptualization, blockchain technology has witnessed continuous and rapid development, bringing profound changes to computer science, law, and economics. In 2008, the initial blockchain system was merely a growing list of records linked together using cryptography. Today, however, blockchains have become the foundation of most digital currencies, robust cloud computing platforms, and dependable databases for tracking supply chain information. Despite challenges and controversies, blockchain technology has the potential to help build a trustworthy and efficient digital world.

However, the emerging blockchain technology has not yet been widely incorporated into current education systems, and there are still a lot of problems and challenges to be solved in this domain. To promote the popularization, development, and transformation of blockchain, Ripple founded the University Blockchain Research Initiative (UBRI), a global network of top universities around the world pursuing public education, academic research, technical development, and innovation in blockchain, cryptocurrency, and related financial technologies (FinTech). Since UBRI’s inception in 2018, Ripple has funded more than 40 university partnerships, supporting more than 500 research projects and new or modified course curricula for more than 280 university courses.
