The Advanced GAmma Tracking Array (AGATA) is a European project to develop and operate the next generation gamma-ray spectrometer. AGATA based on technique of energy tracking in electrically segmented high-purity germanium crystals. This requires accurate determination energy, time position every interaction as gamma ray deposits its within detector volume. Reconstruction full path results with very high efficiency excellent spectral response. realization result many technical advances....
Spaceborne radar is central to Earth environmental monitoring and forecasting, for such events as natural hazards, severe weather, snow/ice cover, soil moisture, vegetation canopy, surface defo1mation, ocean circulation winds, much more. Space radars RF sensors today, which include SAR imagers, altimeters scatterometers, are typically designed with mission-unique elements at high cost. No current operational systems combine SAR/Alt/Scat no compact signal generator/processors offer multiple...
Shape parameters of a weakly deformed ground-state band and highly slightly triaxial sideband in $^{42}\mathrm{Ca}$ were determined from $E2$ matrix elements measured the first low-energy Coulomb excitation experiment performed with AGATA. The picture two coexisting structures is well reproduced by new state-of-the-art large-scale shell model beyond-mean-field calculations. Experimental evidence for superdeformation built on ${0}_{2}^{+}$ has been obtained role triaxiality...
In this work we consider agglomeration-based physical frame discontinuous Galerkin (dG) discretization as an effective way to increase the flexibility of high-order finite element methods. The mesh free concept is pursued in following (broad) sense: computational domain still discretized using a but grid should not be constraint for discretization. particular discrete space choice, its convergence properties, and even complexity solving global system equations resulting from dG influenced by...
This paper presents an approach to mesh adaptation suitable for scale-resolving simulations. The methodology is based on the entropy-adjoint approach, which corresponds a standard output-based adjoint method with output functional targeting areas of spurious generation entropy. shows several advantages over error estimation: 1) it computationally inexpensive; 2) does not require solution fine-space problem; and 3) nonlinearly stable respect primal chaotic dynamic systems. In addition, work...
State-of-the-art techniques for vision-based relative navigation rely on images acquired in the visible spectral band. Consequently, accuracy and robustness of is strongly influenced by illumination conditions. The exploitation thermal-infrared purposes studied present paper, as a possible solution to improve close proximity with target spacecraft. Thermal-infrared depend thermal radiation emitted target, hence, they are independent from light conditions; however, suffer poorer texture lower...
In this work the capabilities of a high-order Discontinuous Galerkin (DG) method applied to computation turbomachinery flows are investigated. The Reynolds averaged Navier–Stokes equations coupled with two k-ω turbulence model solved predict flow features, either in fixed or rotating reference frame, simulate fluid around bodies that operate under an imposed steady rotation. To ensure, by design, positivity all thermodynamic variables at discrete level, set primitive based on pressure and...
A Coulomb-excitation experiment to study electromagnetic properties of $^{42}\mathrm{Ca}$ was performed using a 170-MeV calcium beam from the TANDEM XPU facility at INFN Laboratori Nazionali di Legnaro. $\ensuremath{\gamma}$ rays excited states in were measured with AGATA spectrometer.

SUMMARY Discontinuous Galerkin methods are very well suited for the construction of high‐order approximations Euler and Navier–Stokes equations on unstructured possibly nonconforming grids but rather demanding in terms computational resources. In order to improve their efficiency, a p ‐multigrid solution strategy is here considered equations. particular, line smoother will be used alleviate effect stretched convergence rate. The effectiveness efficiency proposed approach compressible...
Inertial Measurement Units (IMUs) are a valid alternative to optical tracking systems for human motion capture, but they subject several disturbances that limit their accuracy. We aim improve the accuracy of elbow joint angle estimation from IMU measurements by introducing novel postprocessing algorithm uses anatomical constraints and does not require any prior calibration or knowledge anthropometric parameters. propose new error model addresses sensor misalignment fusion errors. use an...
