We present a comprehensive set of convergence tests which explore the role of various numerical parameters on the equilibrium structure of a simulated dark matter halo. We report results obtained with two independent, state-of-the-art, multi-stepping, parallel N–body codes: PKDGRAV and GADGET. We find that convergent mass profiles can be obtained for suitable choices of the gravitational soften...

This paper presents a new experimental approach to simulate projected autonomous driving styles based on the accelerations at three road profiles. This study was focused on the determination of ranges of accelerations in triaxial direction to simulate the autonomous driving experience. A special device, known as the Automatic Acceleration and Data controller (AUTOAccD), has been developed to gu...

Abstract High sensitive triaxial accelerometers are used in several space missions to measure the non-gravitational accelerations acting on spacecraft. Among these, capacitive developed for ESA JUICE and BepiColombo were designed of order 3∙10 -6 m/s 2 with an accuracy level 300 ppm frequency range (3·10 -5 - 0.1) Hz. Despite signal be measured is same magnitude seismic noise earth, accurate on...

GRACE and GRACE-FO require the reduction of non-gravitational accelerations, through an onboard accelerometer, to accurately estimate variations in Earth’s gravitational field. Accuracy accelerometer measurements is vital this mass change recovery significant errors will reduce quality recovered science data. This paper describes our current characterization error sources accelerometers mitigat...

introduction air pollution has harmful effect on human health and the environment. accordingly, considerable effort has been put to analyze the air pollutants. one important issue is the spatial distribution of these pollutants. dispersion of the pollutants released from sources on the ground is mostly driven by the planetary boundary layer where turbulent flow causes mixing of the content of t...

Many effective field theories describing gravity cannot arise from an underlying theory based on Riemann geometry or its extensions to include torsion and nonmetricity but may instead emerge another have a nongeometric basis. The Lagrange density for broad class of such is investigated. action fermions coupled linearized about Minkowski background found terms small deviations Lorentz invariance...

Fast and TReX tools are designed to analyse systems with infinite state spaces. They both implement algorithms computing the set of reachable states of such systems. Since the state space may be infinite, acceleration techniques are used . In this paper, we study the differences between Fast and TReX acceleration techniques and show that although Fast remains in Presburger logics while accelera...
