Structural, electronic, and magneto-optical properties of YVO
Optical and magneto-optical properties of YVO single crystal were studied
in FIR, visible, and UV regions. Two structural phase transitions at 75 K and
200 K were observed and established to be of the first and second order,
respectively. The lattice has an orthorhombic symmetry both above 200 K
as well as below 75 K, and is found to be dimerized monoclinic in
between. We identify YVO as a Mott-Hubbard insulator with the optical gap
of 1.6 eV. The electronic excitations in the visible spectrum are determined by
three -bands at 1.8, 2.4, and 3.3 eV, followed by the charge-transfer
transitions at about 4 eV. The observed structure is in good agreement with
LSDA+ band structure calculations. By using ligand field considerations, we
assigned these bands to the transitions to the , , and states. The strong temperature dependence of these
bands is in agreement with the formation of orbital order. Despite the small
net magnetic moment of 0.01 per vanadium, the Kerr effect of the order
of was observed for all three -bands in the magnetically
ordered phase . A surprisingly strong enhancement of
the Kerr effect was found below 75 K, reaching a maximum of . The
effect is ascribed to the non-vanishing net orbital magnetic moment.Comment: Submitted to Phys. Rev.
Theory of Coexistence of Superconductivity and Ferroelectricity : A Dynamical Symmetry Model
We propose and investigate a model for the coexistence of Superconductivity
(SC) and Ferroelectricity (FE) based on the dynamical symmetries for
the pseudo-spin SC sector, for the displaced oscillator FE sector, and
for the composite system. We assume a minimal
symmetry-allowed coupling, and simplify the hamiltonian using a double mean
field approximation (DMFA). A variational coherent state (VCS) trial
wave-function is used for the ground state: the energy, and the relevant order
parameters for SC and FE are obtained. For positive sign of the SC-FE coupling
coefficient, a non-zero value of either order parameter can suppress the other
(FE polarization suppresses SC and vice versa). This gives some support to
"Matthias' Conjecture" [1964], that SC and FE tend to be mutually exclusive.
For such a Ferroelectric Superconductor we predict: a) the SC gap
(and ) will increase with increasing applied pressure when pressure
quenches FE as in many ferroelectrics, and b) the FE polarization will increase
with increaesing magnetic field up to . The last result is equivalent to
the prediction of a new type of Magneto-Electric Effect in a coexistent SC-FE
material. Some discussion will be given of the relation of these results to the
cuprate superconductors.Comment: 46 page

The article proposes an approach to the formalization of the planning of the production process of missile and artillery armament in the conditions of vertical integration of participants in the production process. The basis of the approach is the representation of participants in the production process in the form of a complex of interconnected enterprises. Each cycle of the production process is presented in the form of a network graph. The arcs of the graph correspond to the particular material technological logistical and financial processes in the overall production process. The peaks reflect events that are the completion of certain sets of these particular processes. With this representation, the planning procedure for each cycle of the production process consists in fixing the specified particular processes for the enterprises of the complex and establishing the times of their beginning and completion, that is, in the construction of the corresponding calendar plan. The problem of its construction is formalized in the form of a nonlinear mathematical programming problem.Π ΡΡΠ°ΡΡΠ΅ ΠΏΡΠ΅Π΄Π»ΠΎΠΆΠ΅Π½ ΠΏΠΎΠ΄Ρ

The model and the planning method of volume and variety assessment of innovative products in an industrial enterprise
In the long term, the innovative development strategy efficiency is considered as the most crucial condition for assurance of economic system competitiveness in market conditions. It determines the problem relevance of such justification strategies with regard to specific systems features and conditions of their operation. The problem solution for industrial enterprises can be based on mathematical models of supporting the decision-making on the elements of the innovative manufacturing program. An optimization model and the planning method of innovative products volume and variety are suggested. The feature of the suggested model lies in the nonlinear nature of the objective function. It allows taking into consideration the law of diminishing marginal utility. The suggested method of optimization takes into account the system features and enables the effective implementation of manufacturing capabilities in modern conditions of production organization and sales in terms of market saturation.

QUANTITATIVE EVALUATION OF THE DIRECTION OF THE STATE CUSTOMS POLICY
The article discusses the method of macroeconomic assessment of the state customs policy. The methodology is based on a comparison of weighted average tariffs of import customs duties on the structure of imports and on the structure of national production of the state in question. Their comparison allows us to quantify the level of customs and tariff protection of national production.Π ΡΡΠ°ΡΡΠ΅ ΡΠ°ΡΡΠΌΠΎΡΡΠ΅Π½Π° ΠΌΠ΅ΡΠΎΠ΄ΠΈΠΊΠ° ΠΌΠ°ΠΊΡΠΎΡΠΊΠΎΠ½ΠΎΠΌΠΈΡΠ΅ΡΠΊΠΎΠΉ ΠΎΡΠ΅Π½ΠΊΠΈ ΡΠ°ΠΌΠΎΠΆΠ΅Π½Π½ΠΎΠΉ ΠΏΠΎΠ»ΠΈΡΠΈΠΊΠΈ Π³ΠΎΡΡΠ΄Π°ΡΡΡΠ²Π°.

The article proposes a model and method for optimizing computing processes in computing systems with a parallel architecture. The construction of the model consists in dividing computer programs for solving problems into relatively independent elements (blocks) and representing the information dependence of the blocks in the form of corresponding oriented graphs. The organization of the computational process in this case consists in the dynamic distribution of the resources of the computing system for implementing the operations of each of the blocks. As an indicator of the effectiveness of this process, the time taken to implement the operations of all blocks of the programs under consideration (the time to solve the corresponding tasks) was taken. The goal of optimization is to shorten the time as much as possible. To form an optimal resource allocation, a method based on the branch and bound procedure is proposed.ΠΡΠ΅Π΄Π»ΠΎΠΆΠ΅Π½Ρ ΠΌΠΎΠ΄Π΅Π»Ρ ΠΈ ΠΌΠ΅ΡΠΎΠ΄ ΠΎΠΏΡΠΈΠΌΠΈΠ·Π°ΡΠΈΠΈ Π²ΡΡΠΈΡΠ»ΠΈΡΠ΅Π»ΡΠ½ΡΡ
