As part of the plane strain, the problem on steady oscillations of the inhomogeneous through-thickness isotropic poroelastic layer with voids is considered. The layer bottom is connected with the perfectly rigid foundation, the oscillations are caused by the surface stress on the top face. Under the known inhomogeneit…
Tumbling drums are widely applied in various mechanical engineering branches. The basic deficiency of such technological machines is high intensity of the sound radiation. In modern drums, quiet drives are applied. In practice, the excess of the sanitary noise code is created by the sound radiation of the drum body un…
The statement of the axisymmetric consolidation problem for a porous, non-homogeneous in-depth half-space, and the construction of the fundamental solution to defining the displacement fields, strains, stresses, and pore pressure under the given boundary conditions are considered. The solution to the equations describ…
The operational and industry characteristics of the creation and development of the innovation process in the agribusiness are defined. The situation in this field is described as rather acute. To a large extent, it is caused by the transition deformations. The innovation process is considered by the author as a relat…
The theoretical investigation of the noise and vibration of the rail as a line limited distance elastically mounted source is resulted. When installing the rail on sleepers, it is presented as a system of two-point sources simultaneously radiating the sound energy, and every section of the rail between the sleepers –…
To reduce secondary processing such as sanding or chemical etching in the manufacture of composite structures, we present an in-mold surface preparation process using imprint lithography on carbon/epoxy composite adhesive joints. In the proposed in-mold process, microstructures are designed and fabricated on the surfa…
The design of the shock-vibrating finish machining with a ball-and-rod reinforcer (BRR) is considered. The essence of the method and the tool design are described. The effective application domains for the ball-and-rod reinforcer are offered. It is important to note that such processing can be used under the local har…
The construction and practical application issues of the software shell for the development and implementation of the rating assessment coefficient methods of objects (engineering, organizational, etc.) are considered. The given shell is designed for those users who wish to develop and enrich the computer coefficient…
The activating composite halide salts-based coating effect on the existence domains of the argon welding varieties through the reversed polarity current is studied. The research has been conducted under the automatic beading on the plates of steel 20 with wire Sv-08G2S 1.2 mm d — both with the activating composite coa…
The paper covers the description of role of business reputation (goodwill) in the assessment of the investment attractiveness of a business entity. The methodology of the goodwill valuation which allows making investment decisions is taken into account. Advantages and disadvantages of the methods are stated. The fact…
The integrated use of the merchandising tooling implies quality changes in the system of planning and management at the retail enterprise. The system approach to the communication and economic efficiency improvement of the sales promotion and field selling is recognized essential. With this in view, main phases of the…
The analysis of the existing methods of the combined vibratory finishing treatment allows identifying the factors restraining their effective application. To improve the productivity, a fundamentally new process flowsheet of the composite energy action of the operating environment on the working surface is offered. It…
A review of papers on martensitic transformations is presented. To clarify the martensite nucleation mechanism in iron-carbon steels on the basis of the currently established understanding is the main purpose of the review. The martensitic transformation is one of the main types of phase transformations in the solid s…
The efficiency improvement necessity of the technological process design for the multiproduct manufacture is proved. The information model of the liberal manufacturing and technological solution based on the standard technological systems application at the pre-production stages is offered and considered. The design m…
An axisymmetric contact problem of the elasticity theory on the torsion of the transversely isotropic half-space with the inhomogeneous coating by the round die is considered. The problem solution is reduced to the integral equation solution using the integral transformations technique. The explicit expression of the…
To improve the performance reliability of the overhead power lines, a redundant phase that can reserve any of the damaged phase conductor, and allow single-phase fusing glaze-ice and rime depositions with conservation of the consumer supply continuity is offered for use. The mode analysis and the subsequent rationale…
As a result of the steel cable security rating, it is essential to determine that the nature, value, and quantity of defects will not exceed the critical reject limits while in operation. The high-temperature impact results in uneven wire heating in the cable operation activity. It leads to the cable deflected mode ch…
The pressure induced superconductivity and structural evolution for Bi2Se3 single crystal have been studied. The emergence of superconductivity with onset transition temperature (Tc) about 4.4K is observed around 12GPa. Tc increases rapidly to the highest 8.5K at 16GPa, decreases to 6.5K at 21GPa, then keep almost con…
We employed a scanning tunneling microscope to image the (001) surface topography and local density of states (LDOS) in La$_{2-2x}$Sr$_{1+2x}$Mn$_2$O$_7$ (x=0.32, LSMO) single crystals below the Curie temperature (T$_C$ = 120 K). The LDOS maps revealed a stripe-like modulation propagating along the tetragonal a axis w…
We report ultrafast transient-grating experiments on heavily p-type InP at 15 K. Our measurement reveals the dynamics and diffusion of photoexcited electrons and holes as a function of their density n in the range 2E16 to 6E17 cm-3. After the first few picoseconds the grating decays primarily due to ambipolar diffusio…
