In The Lancet in 1971, Julian Tudor Hart gave medicine one of its most important insights: the availability of medical care ...

Abstract: In this paper, a recursive closed-loop subspace identification method for Hammerstein nonlinear systems is proposed. To reduce the number of unknown parameters to be identified, the original ...

Artificial intelligence is reshaping how humans see themselves, raising urgent ethical questions about autonomy, agency, and the construction of digital identities. A new study by Bogdan-Andrei Lungu ...

Abstract: We revisit the concept of constraint embedding as a means for dealing with kinematic loop constraints during dynamics computations for rigid-body systems. Specifically, we consider the local ...

Group by account id and product, and then aggregate the number of minutes of each group. The results contain the columns account id, product and number of minutes. We want to pivot the results to the ...

An recursion operation is defined as the process of directly or indirectly calling a procedure repeatedly. The Tower of Hanoi puzzle is one typical example of this. This essay introduces the methods ...
