Treatment of deep channel by self-supporting technological units ("KROT"-type)
# 11, November 2012
DOI: 10.7463/1112.0483374
N.K. Litvin, A.G. Tuktanov
Problems of design and construction of technological "KROT"-type units are considered in this article. These units allow one to eliminate some drawbacks of classical equipment used to treat deep channels. Their basic principle is basing a deep channel on the surface treated by this unit and moving it across the surface as across the guide ways of the machine. The advantage is that maintenance of any product with deep channels can be made under shop-floor conditions, in areas of installation and operation. The product, in this case, can be positioned horizontally, vertically or obliquely.

# 11, November 2012
DOI: 10.7463/1112.0483229
I.S. Kartavcev, N.I. Pas'ko
A classification of inspection sheets for NC machine tools is proposed. It considers several parameters of online monitoring and machine tool adjustment, such as the adjustment type, the possibility of monitoring tool wear by the NC controller, the availability of the dimensional correction in the adjustment cycle, and so forth. Besides, some models of the in-process monitoring of tool wear were considered with different approaches to the process. They represent the dynamics of the process being monitored in the best way. Usage of proposed classification allows one to display parameters affecting the process of numerical machine control onto inspection sheets explicitly. It leads to a simplification of an algorithm of determining its main parameters, which means it allows one to reduce expenses on running control and, in the end, decrease production cost

# 11, November 2012
DOI: 10.7463/1112.0491497
M.I. Salman, D.N. Popov
A method of reducing power required for electromechanical converter by balancing hydrodynamic forces acting on the control valve was considered. To calculate these forces, the finite element method was used; it allows one to determine the shape of the valve’s surface, which provides minimal values of hydrodynamic forces. In addition, graphs were plotted in order to compare the values of hydrodynamic forces obtained with the finite element method for unshaped and shaped spools, for two types of spool-type valve (supply of liquid in the center and along the edges of the valve). Using the finite element method, the distribution of pressure over the surface of the valve having the diameter of 6 mm, in the gap and the cavity of the spool-type valve was performed. Results of computer shaping of the valve and investigation of the influence of manufacturing precision of the valve on balancing hydrodynamic forces are given in the article.

There are considered piecewise affine maps which are simplicial relative to a complete simplicial complex. Of such maps two kinds are studied: contractions (such that the complete preimage of a point is connected) and crumples (such that the image of a nonsingle-point straight-line segment is nonsingle-point broken line). Discrete criteria (with regard to properties of these maps at simplices of corresponding complexes) for such maps are proved.

DOI: 10.7463/1112.0489647
V.N. Trishin
Null solutions of the source-free Maxwell equations in the Minkowski space-time are considered. It is well known that a principal null direction of the null electromagnetic field defines a shear-free geodesic null congruence. Conversely, null Maxwell fields can be obtained from the (analytic) shear-free congruence via the Robinson theorem. We present the explicit formula for the electromagnetic field derived from the Robinson and Kerr theorems. The solution depends on two analytic functions of two and three complex variables.

I.K. Romanova, V.S. Soloviev
The study of aerodynamics of bodies that received permanent deformation in the process of movement is a very important task. The authors developed an efficient matrix method for describing the geometry of bodies with an arbitrarily curved axis; this method was used as the basis for creating a general method for calculating aerodynamic characteristics of such bodies; this general technique is based on the physical "Newtonian inhibition" hypothesis. This approach allows to calculate not only aerodynamic but inertial characteristics of curved bodies; also it can serve as a basis for formation of a combined method of deformed bodies with head and tail surfaces.

 Approaches to the problem of temperature compensation of measuring errors of the channel in pressure sensor for spacecraft operating under severe conditions were considered. It was shown that, for correction and, consequently, for temperature compensation of the pressure sensor output two different methods could be used. The first one is ancillary temperature measurements, the second one is ancillary measurements of reference signals. Technical solutions for creating  thermally isolated cells and electronic circuit for temperature compensation of sensors error were developed and tested. Methods of temperature compensation of zero drift and sensitivity of piezoresistive semiconductor pressure sensors were defined. Values of the temperature error were obtained; they allowed us to put manufactured measurement channel according to GOST 22250-93 into class 0.25 accuracy.

# 11, November 2012
DOI: 10.7463/1112.0500549
A.E. Golubev
In this paper the author considers solving the problem of stabilization of a set angular position of a single-link manipulator when the measurement can only be done by the angular coordinate of the motor shaft. It was sown that synthesis of stabilizing control laws, as well as in the case when measurements can only be done by the angular coordinate of the link manipulator, can be carried out by the principle of separation and bypass integrator in the observer. According to the results of numerical simulation one can draw a conclusion about approximately the same (with the considered initial data and use of the same observer) quality of transient processes of the system with the control found by the bypass integrator in the observer and the control based on the principle of separation and linearization technique using feedback according to the state. The possibility of applying the bypass method to the problem of stabilization can solve this problem also in the case of system disturbances and uncertainties. Possible range of application of the results obtained in the work is solving solve problems of control of technical systems with incomplete information about the state of the measured system.

S.A. Gerasimov, A.A. Novakova, V.S. Kraposhin, P.V. Bocharov
The authors established the influence of preliminary heat treatment (annealing at 950°C, 0.5 hrs, cooled with furnace + tempering at the interval of 500-700°C) on hardness of the nitrided layer of steel 38H2MYUA (nitriding at 500°C, 30 h). Similar results were obtained in a model of carbon-free alloy Fe-4% Cr. By the method of nuclear gamma resonance spectroscopy (the Mossbauer effect) on the model alloy it was established that Fe-Cr clusters are formed during the cooling process starting from 950°C and the subsequent tempering. Clustering affects the size and number of particles of chromium nitride formed during subsequent nitriding at 500°C. Depending on the heat treatment before nitriding, Fe-Cr clusters are characterized by different filling of chromium atoms of the first and second coordination spheres of iron. According to the Mössbauer spectra after annealing at 950°C and tempering at 550°C, during the following 10 hrs before nitriding in the structure of the solid solution clusters are formed, and they correspond to the crystalline structure of  the σ-phase Fe-Cr system: Frank-Kasper polyhedra with 14 vertices.

UK: Universities Drop Traditional Interviews which Could Favour Private School Pupils
# 11, November 2012
Universities are scrapping traditional interviews over concerns that they favour applicants from middle class families and independent schools.The move follows claims that the usual format, where candidates are questioned by a panel of academics, could give an advantage to confident and articulate pupils who have been coached in how to respond.Instead, interviews are being replaced by a “speed dating” style process where each candidate undergoes a series of brief one-on-one “mini-interviews”, solving problems and taking part in roleplays rather than answering general questions about themselves.The new assessments are seen as fairer because they reward innate skills, such as empathy, rather than eloquence.It comes as universities face increasing pressure from the Government to broaden their intake and admit more students from poorer families and state schools.Sixth formers applying this month to study medicine, dentistry or veterinary science at at least five institutions around the UK will undergo the new speed dating style assessments.
