The increasing global demand for air travel over the past three decades has led to heightened congestion, environmental concerns, and operational inefficiencies. This study explores potential of commercial aircraft formation flight, inspired by energy-saving flight patterns migratory birds, enhance fuel efficiency on busy Melbourne Sydney city-pair route. methodology is divided into macroscopic microscopic levels, addressing both strategic planning detailed optimisation. level focuses route...
Abstract We investigate the properties of voids and void galaxies in TNG300 simulation. Using a luminous galaxy catalog spherical void-finding algorithm, we identify 5078 at redshift z = 0. The cover 83% simulation volume have median radius 4.4 h −1 Mpc. two populations field based on whether reside within (“void galaxies”; 75,220 objects) or outside (“nonvoid 527,454 objects). Within voids, mass does not directly trace light. Instead, mean radial underdensity profile as defined by locations...
Abstract Recent cosmological hydrodynamical simulations have produced populations of numerical galaxies whose global star-forming properties are in good agreement with those observed galaxies. Proper modeling energetic feedback from supernovae and active galactic nuclei is critical to the ability reproduce galaxy properties, historically, such has proven be a challenge. Here, we analyze local central satellite z = 0 snapshot TNG100 simulation as test models. We generate face-on projection...
Active asteroids behave dynamically like but display comet-like comae. These objects are poorly understood, with only about 30 identified to date. We have conducted one of the deepest systematic searches for asteroid activity by making use deep images from Dark Energy Camera (DECam) ideally suited task. looked indicators among 11,703 unique extracted 35,640 images. detected three previously active ((62412), (1) Ceres and (779) Nina), though (62412) showed signs activity. Our occurrence rate...
Abstract The great comet C/1995 O1 (Hale–Bopp) presented a remarkable opportunity to study its long-term brightness over four years. We used 2240 observations published in the International Comet Quarterly from 17 observers during 1995 July 1999 September create secular lightcurve. In order account for observer differences, we present novel algorithm reduce scatter and increase precision lightcurve compiled many sources. It is implemented publicly available code, ICQSPLITTER, which uses...
Generative Adversarial Networks (GANs) are a recent advancement in unsupervised machine learning. They cat-and-mouse game between two neural networks: [1] discriminator network which learns to validate whether sample is real or fake compared training set and [2] generator generate data that appear belong the set. Both networks learn from each other until complete able produce samples indistinguishable We find GANs well-suited for fast generation of novel 3D density maps those obtained N-body...
Rapid adoption of machine learning (ML) technologies has led to a surge in power consumption across diverse systems, from tiny IoT devices massive datacenter clusters. Benchmarking the energy efficiency these systems is crucial for optimization, but presents novel challenges due variety hardware platforms, workload characteristics, and system-level interactions. This paper introduces MLPerf Power, comprehensive benchmarking methodology with capabilities evaluate ML at levels ranging...
We present radial profiles of luminosity-weighted age, $age_L$, and $\Delta \Sigma_{SFR}$ for various populations high- low- mass central satellite galaxies in the TNG100 cosmological simulation. Using these profiles, we investigate impact intrinsic environmental factors on distribution star formation. For both satellites, effects black hole mass, cumulative AGN feedback energy, morphology, halo local galaxy overdensity profiles. In addition, dependence as a function redshifts at which they...

The long-term brightness evolution of the great comet C/1995 O1 (Hale-Bopp) presented a remarkable opportunity to study behavior its coma over four years. We used approximately 2200 total visual magnitudes published in International Comet Quarterly taken from 17 observers during period 1995 July - 1999 September create secular lightcurve. In order account for observer differences, we present novel algorithm reduce scatter and increase precision lightcurve compiled many sources. It is...
