Opis:
Optical data storage is a rapidly developing technique, which emerges in many varieties. Magneto-optical recording, in particular, applies amorphous rare earth/transition metal films, where a binary coded information is written thermomagnetically and is read by the magneto-optical Kerr or Faraday effect. To increase the writing speed and the recording density, techniques for direct overwrite and magnetically induced superresolution were proposed, which involve these of exchange coupled double layer systems as a storage media. In this paper, the principles and the properties of exchange coupled double layers are discussed with respect to the direct overwrite and the magnetically induced superresolution processes. A formalism based on a switching field diagram is developed yielding all information necessary to achieve reliable and practical writing procedures. As an example, the direct overwrite capability is demonstrated experimentally in antiparallel coupled layer systems.

Opis:
Angular differential cross-sections for the formation of H, as a result of electron capture by proton from He$\text{}^{+}$(1s) at the centre-of-mass energies from 4 to 24 keV, are calculated using distorted wave Coulomb-Born approximation. The total interaction potentials in the prior-interaction channel and in the post-interaction channel are considered. Coulomb boundary conditions are taken care of with the proper choice of the perturbation potentials in both the prior and the post channels. A prior-post discrepancy is noted. Existing theoretical results are presented along with the present results.

Opis:
n modern vehicles the steering systems are still widely equipped with power-assisted steering pumps. In most cases vane pumps are used which limit the fluid volume flow in dependence of required pressure and running speed by a special design of the internal control valve. This control valve internally redirects the volume flow inside the pump leading still to unnecessary fluid circulation. Variable displacement pumps now offer an additional opportunity to eliminate the internal volume flow in dependence of the required load with reduced losses and hence increased efficiency. This is realized by a variable adjustment of the displacement cells, but simultaneously the variable force and load distributions inside the pump make the acoustic optimization even more difficult. In this paper the kinematics of the vane pump are modelled with a combined analytical and numerical approach. The data out of this model are used as input data for the hydraulic model of the variable displacement vane pump with a commercial tool. Both models are validated with data from test rig investigations. With this validated virtual prototype different design options are developed and finally successfully investigated on a test rig and in a passenger vehicle.
W nowoczesnych pojazdach układy kierownicze obecnie wyposażane są w pompy wspomagająjce. W wielu przypadkach pompy te ograniczają objętościowe natężenie przepływu w zależności od ciśnienia i prędkości obrotowej za pomocą specjalnego zaworu regulacyjnego. Zawór ten ustala przepływ wewnątrz pompy, powodując niepożądane cyrkulacje rzeczy. Pompy o zmiennej objętości zapewniają obecnie dodatkowe korzyści dostosowując przepływ wewnątrz w zależnożci od obciążenia przy zapewnieniu mniejszych strat i większej sprawności. Jest to realizowane przez regulacje zmian objętosci komór, jednakże jednoczesne zmiany sił i rozkładu obciążenia wewnątrz pompy sprawiają, że proces jej optymalizacji akustycznej jest bardzo trudny. W artykule przedstawiono kinetyczny model wraz z jego analitycznym i numerycznym opisem. Dane wyjściowe tego modelu wykorzystano jako dane wejściowe do modelu hydraulicznego pompy o zmiennej objętości, utworzonego za pomocą standardowych narzędzi. Oba modele zweryfikowano za pomocą danych ze stanowiska badawczego. W wyniku tej weryfikacji opracowano różne warianty konstrukcji pomp, które następnie przebadano na stanowisku badawczym i w samochodzie osobowym.

Opis:
Reliable knowledge of a ship’s position and movement in relation to other traffic participants and obstacles is a fundamental requirement for navigation and avoiding collisions and groundings. Consequently, the onboard provision of resilient position, navigation and time data (PNT) is emphasized by the International Maritime Organization’s (IMO) e-navigation strategy, solution S3 “Improved reliability, resilience and integrity of bridge equipment and navigation information” and by the assigned risk control option RCO5 “Improved reliability and resilience of onboard PNT systems”. An initial step towards resilient PNT has been realized by the maritime community with the development of the performance standards for shipborne multi-system radionavigation receiver equipment (MRR). This MRR performance standard (PS) supports the full use of data coming from current and future radionavigation systems and services. Consequently, the combined use of several global navigation satellite systems (GNSS) and the additional use of space based augmentation systems (SBAS) as well as optional terrestrial radionavigation systems (e.g. eLoran or R-Mode) will be supported to increase the performance of positioning and timing. As a second step, the development of guidelines for an onboard PNT (data processing) unit has been identified as supplementary and necessary. The starting point is the onboard use of a combination of GNSS receivers and autarkic systems (e.g. radar, gyro, echosounders with bathymetric data) for a comprehensive provision of required PNT data. Redundancy in the available data enables the application of integrity monitoring functions to evaluate the current usability of safety-critical data and components. The aim of the guidelines is the specification of data processing rules towards the resilient provision of standardized PNT data and integrity information. For this purpose, a modular architecture for an onboard PNT system is introduced and scaled to the need for data input as well as the performance of data output.

Opis:
The Compressed Baryonic Matter (CBM) experiment at the future Facility for Antiproton and Ion Research (FAIR) is a heavy-ion experiment designed to study nuclear matter at the highest baryonic density. For high-statistics measurements of rare probes, collision rates of up to 10 MHz are targeted. The experiment, therefore, requires fast and radiation-hard detectors, self-triggered detector front-ends, free-streaming readout architecture, and online event reconstruction. The Silicon Tracking System (STS) is the main tracking detector of CBM, designed to reconstruct the trajectories of charged particles with efficiency larger than 95%, a relative momentum uncertainty better than 2% for particle momenta larger than 1 GeV/c inside a 1 Tm magnetic field, and to identify complex decay topologies. It comprises 876 double-sided silicon strip modules arranged in 8 tracking stations. A prototype of this detector, consisting of 12 modules arranged in three tracking stations, is installed in the mini-CBM demonstrator. This experimental setup is a small-scale precursor to the full CBM detector, composed of sub-units of all major CBM systems installed on the SIS18 beamline. In various beam campaigns taken between 2021 and 2024, heavy ion collisions at 1–2 AGeV with an average collision rate of 500 kHz have been recorded. This allows for the evaluation of the operational performance of the STS detector, including signal-to-noise ratio, charge distribution, time and position resolution, hit reconstruction efficiency, and its potential for track and vertex reconstruction.

Opis:
The global polarization of Λ hyperons along the total orbital angular momentum of a relativistic heavy-ion collision is presented based on the high statistics data samples collected in Au+Au collisions at $\sqrt{^{s}NN}$ = 2.4 GeV and Ag+Ag at 2.55 GeV with the High-Acceptance Di-Electron Spectrometer (HADES) at GSI, Darmstadt. This is the first measurement below the strangeness production threshold in nucleon-nucleon collisions. Results are reported as a function of the collision centrality as well as a function of the hyperon's transverse momentum (p_{T}) and rapidity (y_{CM}) for the range of centrality 0–40%. We observe a strong centrality dependence of the polarization with an increasing signal towards peripheral collisions. For mid-central (20 – 40%) collisions the polarization magnitudes are $\left< P_{\Lambda}\right>$ (%) = 6.8 $\pm$ 1.3 (stat.) $\pm$ 2.1 (syst.) for Au+Au and $\left< P_{\Lambda}\right>$ (%) = 6.2 $\pm$ 0.4 (stat.) $\pm$ 0.6 (syst.) for Ag+Ag, which are the largest values observed so far. This observation thus provides a continuation of the increasing trend previously observed by STAR and contrasts expectations from recent theoretical calculations predicting a maximum in the region of collision energies about 3 GeV. The observed polarization is of a similar magnitude as predicted by 3D-fluid-dynamics and the UrQMD plus thermal vorticity model and significantly above results from the AMPT model.

Opis:
Hadron production ($\pi^{\pm}$, proton, $\Lambda, K^{0}_{S}, K^{\pm}$) in $\pi^{-}$ + C and $\pi^{-}$ + W collisions is investigated at an incident pion beam momentum of 1.7 GeV/c. This comprehensive set of data measured with HADES at SIS18/GSI significantly extends the existing world data on hadron production in pion induced reactions and provides a new reference for models that are commonly used for the interpretation of heavy-ion collisions. The measured inclusive differential production cross-sections are compared with state-of-the-art transport model (GiBUU, SMASH) calculations. The (semi-) exclusive channel $\pi^{-}$ + A $\to \Lambda$ + $K^{0}_{S}$ + X, in which the kinematics of the strange hadrons are correlated, is also investigated and compared to a model calculation. Agreement and remaining tensions between data and the current version of the considered transport models are discussed.
