We show that shot noise in a resonant-tunneling diode biased the negative differential resistance regions of $I\ensuremath{-}V$ characteristic is enhanced with respect to ``full'' noise. provide experimental results showing Fano factor up 6.6, and it dramatic effect caused by electron-electron interaction through Coulomb force, particular shape density states well. also present numerical from proposed theory, which are agreement experiment, demonstrating model accounts for physics relevant...
The grouting of rock used to be a quite empirical constructional technique aimed improve somewhat the physical properties masses which are actually part civil engineering project. Different "grouting schools" or "ways thinking" did develop and considerable number recipes were dictated by "great old men" enforced later on regulations any kind. Only in last decades process started studied more scientific way well-founded results now hand. Nevertheless, improvements still possible even required...
The Large Area Detector (LAD) is the high-throughput, spectral-timing instrument onboard eXTP mission, a flagship mission of Chinese Academy Sciences and China National Space Administration, with large European participation coordinated by Italy Spain. currently performing its phase B study, target launch at end-2027. scientific payload includes four instruments (SFA, PFA, LAD WFM) offering unprecedented simultaneous wide-band X-ray timing polarimetry sensitivity. based on design originally...
The CubeSat solar polarimeter (CUSP) project aims to develop a constellation of two CubeSats orbiting the Earth measure linear polarisation flares in hard x-ray band by means Compton scattering on board each satellite. CUSP will allow study magnetic reconnection and particle acceleration flaring structures. is approved for Phase A Italian Space Agency framework Alcor program aimed technologies missions.
Abstract The Gibraltar strait connection project is a very complex one, from its history to the various aspects of present design stage. preliminary Tunnel was ready in 1996 but revision became unavoidable because new findings about geological conditions. update turned out be rather more than simple review. geotechnical characteristics had reconsidered for purpose geomechanical computations, which focused on possibility realise tunnel worst possible conditions: 200 meters ground overburden...
Abstract The security of data communications is one the crucial challenges that our society facing today. Quantum Key Distribution (QKD) most prominent methods for guaranteeing ultimate based on laws quantum physics. In this work, results obtained during Italian Industry 4.0 Testbed (II4QuTe) project are reported where authors realised a QKD testbed securely connecting Competence Manufacturing (CIM4.0) located in Torino and TIM edge node 10 km away from testbed. accommodates server providing...
Abstract In this modern space exploration era, the lunar site offers new opportunities such as deployment of an X—ray observatory capable observing half sky simultaneously, but also may allowing access to entire solid angle by exploiting rotation moon around its own axis. The Lunar Electromagnetic Monitor in X—rays (LEM—X) is All Sky for band (2–50 keV) based on concept coded aperture camera. basic element camera Wide Field and realize a ”dome” composed N identical modules that observe...
The CUbesat Solar Polarimeter (CUSP) project is a future CubeSat mission orbiting the Earth aimed to measure linear polarization of solar flares in hard X-ray band, by means Compton scattering polarimeter. CUSP will allow us study magnetic reconnection and particle acceleration flaring structures our star. framework Italian Space Agency Alcor Program, which aims develop new missions. approved for Phase B that last 12 months, starting mid-2024. We report on current status as outcome A.
A flow-control method is applied to enhance the efficiency and flow homogeneity of three-dimensional diffusers used in open-jet wind tunnels. Suitably shaped grooves are introduced diffuser diverging walls. The promote relaxation non-slip condition along streamlines bounding small recirculation regions forming passively inside grooves. That reduces momentum losses results a downstream boundary layer with higher momentum, which more separation-resistant. proposed device has been successfully...
The effects of the walls a test section on model in transonic flow were investigated by using AGARD Calibration Model B. Tests carried out closed-circuit pressurized tunnel, with confined square 1.5 m width, tapered slots giving 5% porosity. Two models different dimensions used, 0.85 and 0.056% blockage ratios. Longitudinal aerodynamic characteristics analyzed means measurements performed at varying angles attack (up to 24 deg) Mach numbers from 0.3 1.2. In some conditions wall interference...
Introduction F LOW close to the wing tip is of importance for both low– and high–aspect ratio wings. Indeed, induced drag could be significantly affected by spanwise lift distribution, because there an introduction energy that concentrated at tip. Furthermore, even small errors in prediction flow can affect evaluation structural loads acting on wing. Knowledge physical behavior fully developed vortex well established. However, experimental evidence shows, initial roll-up wing-tip vortex,...
The capabilities of different numerical methods in evaluating the aerodynamic characteristics a forward-swept wing subsonic and transonic e ow are analyzed. results, obtained by means potential, Euler, Navier ‐Stokes solvers, compared with experimental data. In particular, attention is focused on quantities related to pressure distributions. Moreover, an attempt made investigate capability solver predict separation lines; both laminar Navier‐Stokes equations Reynolds-averaged k-« model...
