Language of Criminalistic Research as a Basis for Studying Criminal Legal Phenomena

Dmitriy Mokhorov & Alexander Fedyukovsky
This essay for the inaugural issue of Technology and Language explores the complicated interrelation of conceptual and technological change in the context of scientific development. It shows how these relations become even more complex in the age of information technologies. Criminalistic research offers a case in point. It is defined by a set of technologies and a precise language which serves to render vague legal concepts determinate. Technology is not only used by law enforcement...

Corrosion resistance and mechanical performance of steel reinforcement, before and after shot-blasting process

Ch. Apostolopoulos, Arg. Drakakaki, А.I. Rudskoi, G.Е. Коdzhaspirov & Alk. Apostolopoulos
As it is widely known, corrosion of steel reinforcement is one of the main causes of deterioration of the reinforced concrete structures. Corrosion phenomena combined with seismic loads aggravate the situation. For this reason, in the present paper, an effort is made to upgrade the performance of steel reinforcement against corrosion, using the shot blasting method. Precisely, two groups of specimens were prepared, one of which had previously been shot blasted. Afterwards, the specimens were...

Natural isomers of fullerenes from C4 to C20

Alexander I. Melker & Aleksandra N. Matvienko
We have systematized possible ways of forming the isomers of mini-fullerenes, namely elementary fullerenes: tetrahedron C4, triangular prism C6, cube C8, pentagonal prism C10, hexagonal prism C12, as well as their derivatives, which were obtained by joining elementary fullerenes. Combined with the graph analysis, this approach allows obtain a clear knowledge of their structure. Among them there are barrel-shaped fullerenes: C12, C16, C20; tetrahedral ones C12 and C16; bi-shamrocks C14 and C18, bipyramids C14 and...

Modeling microstructure evolution during thermomechanical processing and heat treatment of steels and predicting their mechanical properties

A.A. Vasilyev, D.F. Sokolov & S.F. Sokolov
An integral computer model/program AusEvol Pro was developed to describe the evolution of steel microstructure during thermomechanical processing (hot rolling, forging), as well as subsequent heat treatment (normalization, tempering), and to evaluate the final mechanical properties (yield stress, tensile stress, elongation), hardness and impact toughness. The program implements a set of physically based models that allow quantitative description of all significant processes of steel structure formation with account of the effects of chemical composition both...

Nano- and microparticle aggregation: unique optical vectors for control

Alexandra G. Bezrukova & Olga L. Vlasova
The multiparameter analysis of simultaneous optical data for systems of nano- and/or micro-particles (3D disperse systems, dispersions, colloids, ensembles with the average diameter less than 10 micrometers) can be presented as the system characteristics characterized by N-dimensional unique vectors of optical parameters that can elucidate changes in the state of system particles. The application of ND unique optical vector approach is shown for several biomedical dispersions at the processes of aggregation. This approach can serve...

Element-free numerical modeling with discrete gradient and its application to crystal defects

A.A. Zisman
The gradient operation has been extended to discrete data in terms of nodal coordinates. On this ground, the nodal strains and related stresses are expressed directly in terms of nodal displacements and the stress divergence in terms of nodal stresses. To make use of truly discrete modeling in computational solid mechanics, the stress balance equation is formulated. For a case study, the latter is applied to an edge dislocation where atom positions of a dislocated...

The Language of Human-Machine Communication

Daria Bylieva
This essay for the inaugural issue of Technology and Language discusses the problem of finding an optimal form of human-machine communication. In the ongoing search for an alien mind, humanity seems to find it not in the infinities of space, but in its own environment. Changes in the language of human-machine interaction made it understandable not only to trained specialists but to every household. In the course of time, home appliances and devices have developed...

Language of Art as Language of Utopia

Natalia Ershova
This essay for the inaugural issue of Technology and Language looks at language and technology coming together in avant-garde art, Russian futurism and constructivism. When words become a visual elements in the composition of new worlds, the creation of words can be seen as a way of breaking with the thinking of the past, but it can also be viewed as a social technology for the construction of a new life. Artists and poets experimented...

Высокочастотное излучение с фронта ударной волны при движении ее в плазме

Александр Сергеевич Барышников, Валерий Александрович Сахаров, Илья Александрович Барышников & Марина В. Чистякова
Теоретически исследуется возможность электромагнитного излучения ударной волны в столкновительной плазме, излучения, которое стимулировано именно движением самой ударной волны. Излучение происходит поперек движению ударной волны и для экспериментов в холодной плазме — на частоте высокочастотного излучения.

Crystallographic orientation, delay time and mechanical constants influence on thermal fatigue strength of single - crystal nickel superalloys

A.V. Savikovskii, A.S. Semenov & L.B. Getsov
The influence of a delay time at the maximum temperature on the number of cycles for the macrocrack initiation for two thermal loading programs was investigated for two single-crystal nickel-based superalloys VIN3 and ZhS32. An analytic approximation of a delay time influence was proposed. Comparison of computational results and analytic formula on the base of constitutive equations with the experimental data was performed for considered single-crystal superalloys and showed a good accuracy. Influence of several...

In the present work, the pair interaction of coaxial circular prismatic dislocation loops (PDLs) arbitrary placed in elastic solids with free spherical surfaces is considered. The analytical solutions for the pair interaction energies of PDLs in an elastic sphere, an elastic medium with a spherical pore and a spherical layer are given in the form of double power series and illustrated by energy maps built in the space of the normalized PDL radii and axial...

MODELING OF STATIC RECRYSTALLIZATION IN COMPLEXLY ALLOYED AUSTENITE

A.A. Vasilyev, S.F. Sokolov Sokolov, D.F. Sokolov & N.G. Kolbasnikov
To predict the kinetics of static recrystallization and the resulting grain size in austenite of alloyed steels including additions of Nb, V, and Ti, a quantitative model is developed. Physically motivated, the model relates the activation energy of the process with that of bulk self-diffusion. The known dependence of the latter on the chemical composition of austenite solid solution, established previously, essentially simplifies the modeling. Employed empirical parameters have been fitted to relevant data covering...
