An important factor of the successful operation of modern enterprises, companies and firms is an active use of modern information technologies. Growth of information flows generates and increases the number of documents that are used. Therefore the purpose of the research is to study the features of the use of one of methods of analysis of functionality of instrumental complexes of the systems of electronic documents circulation taking into account the necessities of establishment of the relatively effective providing of processes of creation, editing, and storage of documents. The used methodology is base on procedure expert evaluation to functionality of instrumental complexes of the systems of electronic documents circulation. By means of the mentioned method accordance of functional possibilities of some instrumental complexes of the systems of electronic circulation of documents, presented on IT of market of Ukraine, is analysed. Ten basic criteria are distinguished. Having conducted the research we have obtained certain results. A study and expert assessment enable determining the best set of electronic document management systems. The experts preferred a set of instrumental functionality of the elDoc system of electronic documents circulation. At the same time we can conclude, that each of studied systems can potentially lead in providing the performance of certain functions. Thus, during the selection of tool set of electronic documents circulation in our environment for small companies and organizations we should consider the specific needs of a particular company, where software will be launched, while paying attention to the implementation in its architecture priority functions.Проанализированы особенности использования одного из методов анализа функциональности инструментальных комплексов систем электронного документооборота с учетом потребностей учреждения относительно эффективного обеспечения процессов создания, редактирования и хранения документов.

Evidence of Color Coherence Effects in W+jets Events from ppbar Collisions at sqrt(s) = 1.8 TeV

We report the results of a study of color coherence effects in ppbar collisions based on data collected by the D0 detector during the 1994-1995 run of the Fermilab Tevatron Collider, at a center of mass energy sqrt(s) = 1.8 TeV. Initial-to-final state color interference effects are studied by examining particle distribution patterns in events with a W boson and at least one jet. The data are compared to Monte Carlo simulations with different color coherence implementations and to an analytic modified-leading-logarithm perturbative calculation based on the local parton-hadron duality hypothesis.Comment: 13 pages, 6 figures.

Search for electroweak production of single top quarks in ppˉp\bar{p} collisions.

We present a search for electroweak production of single top quarks in the electron+jets and muon+jets decay channels. The measurements use ~90 pb^-1 of data from Run 1 of the Fermilab Tevatron collider, collected at 1.8 TeV with the DZero detector between 1992 and 1995. We use events that include a tagging muon, implying the presence of a b jet, to set an upper limit at the 95% confidence level on the cross section for the s-channel process ppbar->tb+X of 39 pb. The upper limit for the t-channel process ppbar->tqb+X is 58 pb. (arXiv

Helicity of the W Boson in Lepton+Jets ttbar Events

We examine properties of ttbar candidates events in lepton+jets final states to establish the helicities of the W bosons in t->W+b decays. Our analysis is based on a direct calculation of a probability that each event corresponds to a ttbar final state, as a function of the helicity of the W boson. We use the 125 events/pb sample of data collected by the DO experiment during Run I of the Fermilab Tevatron collider at sqrt{s}=1.8 TeV, and obtain a longitudinal helicity fraction of F_0=0.56+/-0.31, which is consistent with the prediction of F_0=0.70 from the standard model

Hard Single Diffraction in pbarp Collisions at root-s = 630 and 1800 GeV

Using the D0 detector, we have studied events produced in proton-antiproton collisions that contain large forward regions with very little energy deposition (``rapidity gaps'') and concurrent jet production at center-of-mass energies of root-s = 630 and 1800 Gev. The fractions of forward and central jet events associated with such rapidity gaps are measured and compared to predictions from Monte Carlo models. For hard diffractive candidate events, we use the calorimeter to extract the fractional momentum loss of the scattered protons.Comment: 11 pages 4 figures. submitted to PR
