HackerRank is a pretty cool place to get better at coding. It’s got tons of challenges that really make you think and figure things out faster. Whether you’re just starting out or you’ve been coding ...

Abstract: Sparse arrays can achieve high degree of freedom Direction of Arrival (DOA) estimation by constructing equivalent virtual difference co-array. Due to the existence of holes, however, most ...

Quantifying stratigraphic uncertainty is crucial for reliable risk assessment and informed decision-making in geotechnical and geological engineering. However, accurately modeling complex stratigraphy ...

Near-field focused antenna arrays have emerged as a critical technology for optimising electromagnetic energy delivery and imaging. By finely controlling the phases and amplitudes of individual ...

Ever wonder how some folks just seem to breeze through coding challenges and land those awesome tech jobs? A lot of it comes down to practice, and platforms like HackerRank are super helpful for that.

If folks have libraries who are using SciPy sparse matrices, and you'd like help converting them to run/work with sparse array, this sounds like a nice opportunity to work that out. I wrote a ...
