Adaptive Linearly Constrained Minimum Variance Volumetric Active Noise Control
Traditional volumetric noise control typically relies on multipoint error minimization to suppress sound energy across a region, but offers limited flexibility in shaping spatial responses. This paper introduces a time-domain formulation for linearly constrained minimum variance active noise control (LCMV ANC) for spatial control filter design. We demonstrate how the LCMV ANC optimization framework allows system designers to prioritize noise reduction at specific spatial locations through strat…

Just ordered the respun STM32H750 test board for the Trion T20 devkit.
Hopefully I didn't have any *more* monumental screwups here.
In the meantime, I still have the RGMII test board that I haven't had a chance to assemble and test. Maybe I'll get to that during the week, I have some other stuff to clear out first...

Improved Lower Bounds on Multiflow-Multicut Gaps
Given a set of source-sink pairs, the maximum multiflow problem asks for the maximum total amount of flow that can be feasibly routed between them. The minimum multicut, a dual problem to multiflow, seeks the minimum-cost set of edges whose removal disconnects all the source-sink pairs. It is easy to see that the value of the minimum multicut is at least that of the maximum multiflow, and their ratio is called the multiflow-multicut gap. The classical max-flow min-cut theorem states that when t…

Deadly heat in CHINA. Suffocating heat 24 hours with record hot nights. In particular brutal Minimum of 32.2C at Shanghai which is the hottest night in history for one of the oldest observatories in Asia Nearly all countries in the world have broken heat records in the past weeks. Unprecedented

There is a critical difference between acknowledging the nation’s history and celebrating its worst moments.
In Germany, they don’t erase their shameful Nazi past, but that doesn’t mean they’re erecting hagiographic statues commemorating Nazi war criminals.
While on the subject of war criminals, the National Park Service announced on Monday that the statue of Albert Pike, a northerner who fought for the Confederacy as a brigadier general, would return to its position of honor j…

"When we say monumental, you had better believe it; the 500 pages of this volume, laid out with astonishing detail (and a very small font size) summarize the history and evolution of computers from 1945 to 1990. Throughout these pages, Waldrop reveals that the backbone, the axis, the arrow, the orientation, the mastermind of all that history was none other than Lick himself: he was the incarnation of the phrase “being at the right place at the right time”."

Iterative Sparse Asymptotic Minimum Variance Based Channel Estimation in Fluid Antenna System
With fluid antenna system (FAS) gradually establishing itself as a possible enabling technology for next generation wireless communications, channel estimation for FAS has become a pressing issue. Existing methodologies however face limitations in noise suppression. To overcome this, in this paper, we propose a maximum likelihood (ML)-based channel estimation approach tailored for FAS systems, designed to mitigate noise interference and enhance estimation accuracy. By capitalizing on the inhere…
