Optimal design of an indoor environment using an adjoint RNG k-ε turbulence model [PDF]
The computational fluid dynamics (CFD)-based adjoint method can determine design variables of an indoor environment according to the optimal design objective, such as minimal predicted mean vote (PMV) for thermal comfort.

Quantum RNG Integration in an NG-PON2 Transceiver [PDF]
We propose a minimally invasive optical overlay for time-interleaved QRNG operation in NG-PON2 transceivers. We experimentally demonstrate that random numbers can be generated at a 0.5 Gb/s rate and validate the randomness through statistical tests.

An architecturally constrained model of random number generation and its application to modeling the effect of generation rate [PDF]
Random number generation (RNG) is a complex cognitive task for human subjects, requiring deliberative control to avoid production of habitual, stereotyped sequences. Under various manipulations (e.g., speeded responding, transcranial magnetic stimulation,
