    Abstract- The current development trend, ensuring the welfare of the state, is in constant connection with the activity of innovation. Under the influence of sophisticated and innovative processes, the concept of the national innovation system based on the macroeconomic level is steady in general. Numerous elements are seen in the conjugation of the national innovation system scale, among which higher education institutions and their scientific and innovative potential take their place. However, the reverse side is inequality in the levels of university integration, which introduces a discrepancy between the degree of their effectiveness as the elements of the national innovation system. So it becomes urgent to have a specific set of steps to improve the level of university integration. The process of integration level increase must be governed necessarily by the principles of suitable integration condition supply chain management, where it is possible to justify waiting by the creation of a supply chain management algorithm for university integration in the national innovation system. The result of such an algorithm application is the obtaining of a visual set of steps by a user to ensure the process of managerial decision making and implementation to improve the level of university integration in the national innovation system. The increase of university integration will directly enhance its interaction with other elements of NIS, and therefore will increase its contribution to the national economic development, and other priority areas of the state. Key Words- Innovation, National innovation system, University integration, Supply chain management, Decision-Making algorithm

    Nuclear Polarization of Molecular Hydrogen Recombined on a Non-metallic Surface

    The nuclear polarization of H2\mathrm{H}_2 molecules formed by recombination of nuclear polarized H atoms on the surface of a storage cell initially coated with a silicon-based polymer has been measured by using the longitudinal double-spin asymmetry in deep-inelastic positron-proton scattering. The molecules are found to have a substantial nuclear polarization, which is evidence that initially polarized atoms retain their nuclear polarization when absorbed on this type of surfac

    Precision bond lengths for Rydberg Matter clusters KN (N = 19, 37, 61 and 91) in excitation levels n = 4 - 8 from rotational radio-frequency emission spectra

    Clusters of the electronically excited condensed matter Rydberg Matter (RM) are planar and six-fold symmetric with magic numbers N = 7, 19, 37, 61 and 91. The bond distances in the clusters are known with a precision of +- 5% both from theory and Coulomb explosion experiments. Long series of up to 40 consecutive lines from rotational transitions in such clusters are now observed in emission in the radio-frequency range 7-90 MHz. The clusters are produced in five different vacuum chambers equipped with RM emitters. The most prominent series with B = 0.9292 +- 0.0001 MHz agrees accurately with expectation (within 2%) for the planar six-fold symmetric cluster K19 in excitation level n = 4. Other long series agree even better with K19 at n = 5 and 6. The ratio between the interatomic distance and the theoretical electron orbit radius (the dimensional ratio) for K19 in n = 4 is found to be 2.8470 +- 0.0003. For clusters K19 (n = 6) and K37 (n = 7 and 8) the dimensional ratio 2.90 is the highest value that is found, which happens to be exactly the theoretical value. Clusters K61 and K91 in n = 5 and 6 have slightly lower dimensional ratios. This is expected since the edge effects are smaller. Intensity alternations are observed of approximately 7:3. The nuclear spins interact strongly with the magnetic field from the orbiting electrons. Spin transitions are observed with energy differences corresponding accurately (within 0.6%) to transitions with apparent total (delta)F = -3 at excitation levels n = 5 and 6. The angular momentum coupling schemes in the clusters are complex but well understood.Comment: 37 pages, 14 figure

    The HERMES Polarized Hydrogen and Deuterium Gas Target in the HERA Electron Storage Ring

    Full text link
    The HERMES hydrogen and deuterium nuclear-polarized gas targets have been in use since 1996 with the polarized electron beam of HERA at DESY to study the spin structure of the nucleon. Polarized atoms from a Stern-Gerlach Atomic Beam Source are injected into a storage cell internal to the HERA electron ring. Atoms diffusing from the center of the storage cell into a side tube are analyzed to determine the atomic fraction and the atomic polarizations. The atoms have a nuclear polarization, the axis of which is defined by an external magnetic holding field. The holding field was longitudinal during 1996-2000, and was changed to transverse in 2001. The design of the target is described, the method for analyzing the target polarization is outlined, and the performance of the target in the various running periods is presented

    Response of the ATLAS tile calorimeter prototype to muons

    Get PDF
    A study of high energy muons traversing the ATLAS hadron Tile calorimeter in the barrel region in the energy range between 10 and 300~GeV is presented. Both test beam experimental data and Monte Carlo simulations are given and show good agreement. The Tile calorimeter capability of detecting isolated muons over the above energy range is demonstrated. A signal to background ratio of about 10 is expected for the nominal LHC luminosity (1034cm2sec110^{34} cm^{-2} sec^{-1}). The photoelectron statistics effect in the muon shape response is shown. The e/mip ratio is found to be 0.81±0.03 0.81 \pm 0.03; the e/μ\mu ratio is in the range 0.91 - 0.97. The energy loss of a muon in the calorimeter, dominated by the energy lost in the absorber, can be correlated to the energy loss in the active material. This correlation allows one to correct on an event by event basis the muon energy loss in the calorimeter and therefore reduce the low energy tails in the muon momentum distribution

    Results from a combined test of an electromagnetic liquid argon calorimeter with a hadronic scintillating-tile calorimeter

    Get PDF
    The first combined test of an electromagnetic liquid argon accordion calorimeter and a hadronic scintillating-tile calorimeter was carried out at the CERN SPS. These devices are prototypes of the barrel calorimeter of the future ATLAS experiment at the LHC. The energy resolution of pions in the energy range from 20 to 300~GeV at an incident angle θ\theta of about 11^\circ is well-described by the expression \sigma/E = ((46.5 \pm 6.0)\%/\sqrt{E} +(1.2 \pm 0.3)\%) \oplus (3.2 \pm 0.4)~\mbox{GeV}/E. Shower profiles, shower leakage, and the angular resolution of hadronic showers were also studied

    Evaluation of Fermi Read-out of the ATLAS Tilecal Prototype

    Get PDF
    Prototypes of the \fermi{} system have been used to read out a prototype of the \atlas{} hadron calorimeter in a beam test at the CERN SPS. The \fermi{} read-out system, using a compressor and a 40 MHz sampling ADC, is compared to a standard charge integrating read-out by measuring the energy resolution of the calorimeter separately with the two systems on the same events. Signal processing techniques have been designed to optimize the treatment of \fermi{} data. The resulting energy resolution is better than the one obtained with the standard read-out

    The energy loss spectrum of 150 GeV muons has been measured with a prototype of the ATLAS hadron calorimeter in the H8 beam of the CERN SPS.\\ The differential probability dP/dvdP/dv per radiation length of a fractional energy loss v=ΔEμ/Eμv = \Delta E_{\mu} / E_{\mu} has been measured in the range v=0.01÷0.95v = 0.01 \div 0.95 ; it is then compared with the theoretical predictions for energy losses due to bremsstrahlung and production of electron-positron pairs or of energetic knock-on electrons.\\ The integrated probability 0.010.95(dP/dv)dv\int_{0.01}^{0.95} (dP/dv) dv is (1.610±0.015stat.±0.105syst.)103(1.610\pm0.015_{stat.}\pm0.105_{syst.})\cdot10^{-3} in agreement with the theoretical predictions of 1.5561031.556\cdot10^{-3} and 1.6191031.619\cdot10^{-3}. %7.8.96 - start Agreement with theory is also found in two intervals of vv where production of electron-positron pairs and knock-on electrons dominates. In the region of bremsstrahlung dominance (v=0.12÷0.95v = 0.12\div0.95) the measured integrated probability (1.160±0.040stat±0.075syst)104(1.160\pm0.040_{stat}\pm0.075_{syst})\cdot 10^{-4} is in agreement with the theoretical value of 1.1851041.185 \cdot 10^{-4} , obtained using Petrukhin and Shestakov's \cite{PS} description of the bremsstrahlung process. The same result is about 3.6 standard deviations (defined as the quadratic sum of statistical and systematic errors) lower than the theoretical prediction of 1.472104 1.472\cdot 10^{-4}, obtained using Tsai's \cite{TS} description of bremsstrahlung
