kashafrud formation, siliciclastic strata, middle jurassic in age, commences with basal fluvio conglomerates. the strata are described in terms of 3 facies association (conglomerate, sandstone and mudstone), which were deposited in a fluvio-deltaic and turbities environments. the basal kashafrud strata at 2 areas (8 sections), in the eastern kopet-dagh basin, consist predominantly of boulder to...

in this paper, a photonic crystal waveguide with point defects and lattice constant perturbations of +5%, -5% are being investigated. firstly waveguide structures with constant and specific parameters are being studied and photonic band gap diagrams for te/tm modes are depicted; then pulse propagation in the frequencies available in the band gap are shown. after that, effects of parameters like...

In this article, the method of hard rock mining by undercutting or back incision using asymmetrical disk tools as an alternative to milling with use cutting was described. The results modelling penetration a single asymmetric tool edge into artificial and natural sample were presented compared empirical laboratory tests. effect stand tests for samples mounted on rotating plate presented. carrie...

We study the problem, initiated in [8], of finding randomized and quantum complexity of initial-value problems. We showed in [8] that a speed-up in both settings over the worst-case deterministic complexity is possible. In the present paper we prove, by defining new algorithms, that further improvement in upper bounds on the randomized and quantum complexity can be achieved. In the Hölder class...

Business Processes describe operations of an organization. However, they do not take into account such aspects as detailed logic specification or process implementation. Business Rules are generally better suited for these purposes. Although there is ongoing research on integration of Business Processes with Business Rules, there is no standardized methodology for this integration. We propose a...

The theoretical aspects of the linear chain method for numerical modelling nuclear transmutation systems, and particularly regarding trajectory analysis (TTA), are presented. background TTA method, as an advanced version with detailed description applied mathematical set-up graphical visualisation transformation chains, is shown. As was initially developed at AGH University Science Technology a...
