This documents describes the technical design and expected performance of Barrel DIRC detector for PANDA experiment. The will provide hadronic charged particle identification in polar angle range $22^\circ$ to $140^\circ$ momenta between 0.5 GeV/c 3.5 GeV/c. is based on successful BaBar with several key improvements. system cost were optimized detailed simulations validated full prototypes using beams at GSI CERN. final meets or exceeds PID goal clean $π/K$ separation least 3 standard...
Contemporary fluid motion modelling techniques, including the phenomenon of liquid sloshing in tanks, are increasingly associated with use artificial intelligence methods. In addition to still frequently used traditional analysis methods and such as FEM, CFD, VOF FSI, there is an increasing number publications that elements intelligence. Among others, neural networks deep learning techniques here field prediction approximation, well genetic other multi-agent algorithms for optimization. This...
Baryon-to-meson Transition Distribution Amplitudes (TDAs) encoding valuable new information on hadron structure appear as building blocks in the collinear factorized description for several types of hard exclusive reactions. In this paper, we address possibility accessing nucleon-to-pion (πN) TDAs from $$\bar pp \to e^ + - \pi ^0 $$ reaction with future P̄ANDA detector at FAIR facility. At high center-of-mass energy and invariant mass squared lepton pair q 2, amplitude signal channel admits...
Simulation results for future measurements of electromagnetic proton form factors at $\overline{\rm P}$ ANDA (FAIR) within the PandaRoot software framework are reported. The statistical precision with which can be determined is estimated. signal channel $\bar{p}p\rightarrow e^{+}e^{-}$ studied on basis two different but consistent procedures. suppression main background channel, i.e. \pi^{+}\pi^{-}$ , studied. Furthermore, versus efficiency, and systematical uncertainties extracted evaluated...
This paper summarises a comprehensive Monte Carlo simulation study for precision resonance energy scan measurements. Apart from the proof of principle natural width and line shape measurements very narrow resonances with PANDA, achievable sensitivities are quantified concrete example charmonium-like X(3872) state discussed to be exotic, larger parameter space various assumed signal cross-sections, input widths luminosity combinations. PANDA is only experiment that will able perform scans...

The main purpose of the work which was carried out and is presented in this paper to examine possibility using fuzzy logic inference for conducting a risk analysis with help sheet-based Failure Mode Effects Analysis method (FMEA). At beginning, features analysed were presented, particular emphasis put on Risk, Priority Number parameters. Then, proposal has been made suggests Matlab Fuzzy Logic Toolbox package order convert factors into form sets define rules process made. Finally, created...
This paper presents an analysis of potential failures hydraulic components on the example a gear pump with use instruments quality management. The “five why” method was implemented to evaluate as well bases for causes which have influence pumps failures. are connected operation condition and working fluid. In next step, by using systematic diagram, appropriate improvement actions identified were determined.
The article presents results of research on an adjustable check valve. In particular, the deals with improvement flow characteristics and reduction in pressure losses existing valve design. subject was body form a steel block intended for mounting typical cartridge insert. Two variants were analysed: standard one, which is currently production, proposed new solution, geometry modified based CFD simulations. main task to properly shape arrange holes channels inside body, between connecting...
Flow control valves are designed to maintain a constant flow rate regardless of pressure changes. However, standard, two-way design may cause significant energy losses due the need high in supply line. In contrast, proposed three-way valve allows required be obtained at slightly above loading pressure. This work included building mathematical and simulation models, conducting numerical simulations Ansys/Fluent Matlab/Simulink environments, verifying results by initial test bench experiments...
Reducing energy consumption and increasing operational efficiency are currently among the leading research topics in design of hydraulic systems. In recent years, system modeling techniques have rapidly expanded, especially using artificial intelligence methods. Due to variety algorithms, methods, tools intelligence, it is possible consider prospects directions their further development. The analysis most publications allowed three technologies be indicated, including neural networks,...
