A wave model of torsional vibrations of rotating drill strings is set up. The ranges of rotational speed in which self-excited vibrations occur are found. Andronov-Hopf bifurcations occur at the limits of these ranges. The conditions for the occurrence and development of self-excited oscillatory processes are established. © 2011 Springer Science+Business Media, Inc. Source

The finite-element method is used to determine the stress state around arched mine workings in a mineral bed. Both presence and dip of the mineral bed have a strong effect on the stress state around the mine working. Recommendations for design of mine-working support are formulated © 2011 Springer Science+Business Media, Inc. Source

A model that determines the influence of the factors to urban regions for housing construction is under consideration is proposed in this report. For disclosure of the influence process the technology is used, which is based on fuzzy sets and which is extended to type-2. The basic theoretical aspects are described using sets and graphs that are elucidated in soft computing format. © 2016 National University Lviv Polytechnic. Source

We developed a numerical method for solving the plane problem of nonstationary vibrations of a piezoceramic prismatic body with rectangular cross-section under mechanical loading. How the vibrations of the body with clamped edge are excited and propagate is studied. The dynamic state of bodies of different widths is analyzed. The time dependence of the thickness and transverse displacements is plotted. The distribution of the electric potential over the width of the body is illustrated © 2010 Springer Science+Business Media, Inc. Source

In the title compound, C29H20N2, the dihedral angles subtended by the central p-phenylenediamine ring with respect to the mean plane of the terminal pyrenyl ring system (r.m.s. deviation = 0.027 Å) and the terminal N-phenyl ring are 29.34 (4) and 43.43 (7)°, respectively. The conformation about the C=N bond is E. In the crystal, molecules are linked by N - H⋯π and C - H⋯π interactions forming chains propagating along the [102] direction. These chains are linked via π-π interactions [inter-centroid distances are in the range 3.5569 (11)- 3.708 (1) Å], forming slabs lying parallel to (304). Source
