PROBLEMS OF INTELLECTUAL CAPITAL MANAGEMENT OF ENTERPRISES
The article highlights the key issues of intellectual capital management of enterprises. The existence of these problems has a systemic nature and their solution goes beyond the micro level of business. Intellectual capital, as an object of management, is not homogeneous. There are many related and adjacent concepts. The improvement of the terminology apparatus is based on the study of the essential characteristics of certain categories and the identification of the links between them. A separate problem is the structuring of intellectual capital. Within the three traditional constituents (human, organizational and consumer capital), the author presents his own specification of elements of intellectual capital. The problem of the economic evaluation of intellectual capital and its elements lies in the subjectivity of existing methods. Comparative analysis of evaluation methods, identifying their advantages and disadvantages for individual cases allows us to find the best way to evaluate. The author proposes solving the problem of methodology of intellectual capital management at the intersection of functional and process approaches to management. The obtained results have a theoretical character and are the basis for development of applied methods of management of intellectual capital of enterprises.The article highlights the key issues of intellectual capital management of enterprises.

Competing charge density waves and temperature-dependent nesting in 2H-TaSe2
Multiple charge density wave (CDW) phases in 2H-TaSe2 are investigated by
high-resolution synchrotron x-ray diffraction. In a narrow temperature range
immediately above the commensurate CDW transition, we observe a multi-q
superstructure with coexisting commensurate and incommensurate order
parameters, clearly distinct from the fully incommensurate state at higher
temperatures. This multi-q ordered phase, characterized by a temperature
hysteresis, is found both during warming and cooling, in contrast to previous
reports. In the normal state, the incommensurate superstructure reflection
gives way to a broad diffuse peak that persists nearly up to room temperature.
Its position provides a direct and accurate estimate of the Fermi surface
nesting vector, which evolves non-monotonically and approaches the commensurate
position as the temperature is increased. This behavior agrees with our recent
observations of the temperature-dependent Fermi surface in the same compound

Structural disorder versus chiral magnetism in CrNbS
The crystal structure of a disordered form of CrNbS has been
characterized using diffraction and inelastic scattering of synchrotron
radiation. In contrast to the previously reported symmetry (P622), the
crystal can be described by a regular twinning of an average P6 structure
with three disordered positions of the Cr ions. Short-range correlations of the
occupational disorder result in a quite intense and structured diffuse
scattering; a static nature of the disorder was unambiguously attributed by the
inelastic x-ray scattering. The diffuse scattering has been modeled using a
reverse Monte-Carlo algorithm assuming a disorder of the Cr sub-lattice only.
The observed correlated disorder of the Cr sub-lattice reduces the temperature
of the magnetic ordering from 130 K to 88 K and drastically modifies the field
dependence of the magnetization as it is evidenced by the SQUID magnetometery.
We conclude, that in contrast to the helicoidal spin structure assumed for
P622 form, the compound under study is ferromagnetically ordered with a
pronounced in-plane anisotropy

Real time plasma equilibrium reconstruction in a Tokamak
The problem of equilibrium of a plasma in a Tokamak is a free boundary
problemdescribed by the Grad-Shafranov equation in axisymmetric configurations.
The right hand side of this equation is a non linear source, which represents
the toroidal component of the plasma current density. This paper deals with the
real time identification of this non linear source from experimental
measurements. The proposed method is based on a fixed point algorithm, a finite
element resolution, a reduced basis method and a least-square optimization
formulation
