7730569/243762 Functional matrix rank computation
# 10, October 2011 A problem of finding rank of nonsquare functional matrix, whose elements are smooth functions, is considered. Such matrices arise in course of analysis of regularity and involutivity of vector distributions. To find rank of these matrices, it is convenient to use computer algebra systems, which can perform symbolic computations. Alternative to checking all possible minors is the Gauss algorithm of transforming matrix to rowechelon form. When considering regularity and involutivity, it is often of interest to know the rank of a matrix in the neighborhood of a point. Usual Gauss algorithm cannot answer this question, since it is possible for basis minor to become zero at chosen point. A modified algorithm is presented. This algorithm allows to say if there exists a neighborhood of constant rank containing a chosen point. Examples are presented.
7730569/239866 The properties of the distribution of Gaussian packets on a spatial network.
# 10, October 2011 The description of the statistical behavior of Gaussian packets on a metric graph is considered. Semiclassical asymptotics of solutions of the Cauchy problem for the Schrodinger equation with initial data concentrated in the neighborhood of one point on the edge, generates a classical dynamical system on a graph. In a situation where all times for packets to pass over edges are linearly independent over the rational numbers, a description of the behavior of such systems is related to the numbertheoretic problem of counting the number of lattice points in an expanding polyhedron. In this paper we show that for the final compact graph packets almost always are distributed evenly. The formula for the leading coefficient of the asymptotic behavior of the number of packets with an increasing time is obtained. The situation is also discussed where the times of passage over the edges are not linearly independent over the rationals.
7730569/239840 Path following simulation of wheeled vehicle
# 10, October 2011 Stabilization algorithm of the wheeled vehicle on the planned path is studied by means of numerical modeling. Synthesis of stabilization algorithm is based on theory of normal form of the affine system. Smoothing algorithm of the first derivative of curvature in the case of setting the path by parametric cubic spline is suggested. Methods of finding distance from the wheeled vehicle to the planned path are considered. Efficiency of the method is shown, high sensitivity of control to curvature of the path is established.
7730569/239563 Feynman formula for semigroups with multiplicatively perturbed generators
# 10, October 2011 A new method of describing linear dynamics is considered. This method is based on representations of corresponding evolution semigroups (or, what is the same, representations of solutions of corresponding evolution equations) by Feynman formulae, i.e. by limits of nfold iterated integrals, when tends to infinity. Green functions of many initialboundary value problems are not known explicitly, whereas it is possible to obtain Feynman formulae containing only elementary functions as integrands for some of these problems. Such Feynman formulae, that allow to calculate solutions of evolution equations directly, to approximate transition probabilities of stochastic processes, are useful for computer modeling of quantum and stochastic dynamics. The notion “Feynman formula” (in this context) and the method to obtain such formulae were introduced in works of Smolyanov and his coauthors in the late nineties. In the last decade it has been actively applied to describe different types of dynamics in domains of Euclidean spaces and Riemannian manifolds, in infinite dimensional linear and nonlinear spaces. In the present note the multiplicative perturbations of generators of strongly continuous semigroups on a Banach space of some continuous functions are considered. A Feynman formula is obtained for the semigroups with perturbed generators. Therefore, a new formula is given for the description and the investigation of the perturbed dynamics. Also some particular examples, when the obtained Feynman formula contains only elementary functions as integrands, are considered in this note.
7730569/239583 Visual modeling of spaceships angular motion
# 10, October 2011 The paper describes KOKON software package developed at the Mathematical modeling Department (FN12) of Bauman Moscow State Technical University. The software allows to construct visual threedimensional models of spacecrafts and spacestations. Realistic 3D Stereo visualization is also included. The process of spacecraft motion and, in particular, angular rotation of the spacecraft under the influence of attitude control can be simulated and visualized. The developed software also contains tools for visual design of threedimensional models.
7730569/236936 Affine System Controllability Condition
# 10, October 2011 This note deals with a controllability condition for affine systems with scalar control on all space of states for any final interval of time. Research is based on system transformation to a quasicanonical form and the further analysis of terminal problem solution existence for the transformed system. It is shown that for system with the right part of a special form the terminal problem has the solution for any initial and final states of system and any interval of time. Thereby it is proved that such system is controlled on all space of states for any final interval of time. A possible scope of the received results is the solution of technical systems control problems.
7730569/236859 Asymptotic stabilization of linear Lagrange's systems with delayed controls
# 10, October 2011 The author considers the problem of a Lagrange's system equilibrium point asymptotic stabilization with delay in the control loop. For linear Lagrangian systems of a general type the author found dynamic feedback providing the solution of a task in view. The offered approach is based on the use of change of variables excluding delay from the control loop, keeping the plant equations of motion without changes. The considered change of variables represents the modified transformation known as an Artstein reduction. The energy method is applied to solving the stabilization problem for the system in the new variables. Efficiency of the offered control method is shown trough numerical simulations. The results received in this note can be used to design control algorithms for mechanical systems under conditions of limited speed of reception, processing and transfer of an operating signal.
7730569/217245 On principal ideal rings with divisors of zero
# 10, October 2011 The problem under consideration is a generalized concept of a principal ideal ring and does not suggest that the ring does not have divisors of zero. The problem of classification of principal ideal rings in the new sense and their connection with principal ideal rings in the usual sense are investigated. It is proved that each principal ideal ring (maybe with divisors of zero) without nilpotent elements can be decomposed into a direct product of finitely many principal ideal rings without divisors of zero. For principal ideal rings with nilpotent elements the classification problem is not studied.
7730569/236884 The compatibility test of measurement data, produced by different magnetometers onboard an Earth artificial satellite
# 10, October 2011 Complicated mathematical models are usually used for processing measurements of the Earth magnetic field carried out onboard an Earth artificial satellite. It is desirable to verify the measurement data by humble tools before such processing. If a few onboard magnetometers made their measurements at the same instants, then one ought to check a simple geometrical compatibility of the measurement data. One can estimate constant shifts in the data and transition matrices between proper coordinate systems for each pair of magnetometers in case the check proved to be successful. Below, we described the method for checking the compatibility of the measurement data produced by two magnetometers. We illustrate the method by checking the compatibility of the magnetic measurements produced by the equipment Mirage onboard Foton M2.
7730569/236916 Flat control systems and transformations of Cspectral Vinogradov sequences
# 10, October 2011 Control systems that have a linearizing output are called flat. Solutions of such system are expressed through functions of this output and a finite set of their derivatives according to the system. Such output allows to synthesize control algorithm in the form of dynamic feedback. In the article the problem of flatness checking is investigated by methods of infinitedimensional differential geometry. Earlier this problem was reformulated as the problem of search of an invertible differential operator which transforms a column of given 1forms to a column of exact 1forms. In the article an equation for such an operator is derived. The solubility of this equation means flatness of system.
77  30569/233615 Output feedback control of ships planar motion
# 10, October 2011 This note deals with a ship positioning control problem. The dynamics considered are nonlinear ship dynamics on the plane. Only the center of mass coordinates and yaw angle are supposed to be physically measured. The main result states that separation principle holds for the nonlinear model in question. Specifically, the stabilizing control law is synthesized in two steps. First, the state feedback control law is found using the feedback linearization technique. Then, the global asymptotical observer is designed and the observer’s state is put into the state feedback control instead of the system’s state. The resulting system in closedloop with the observer state feedback is shown to be globally asymptotically stable. The proved theoretical results are also illustrated through simulation.

This article considers quadratic sums of a dispersive analysis equation and their independence is proved. Necessary and sufficient conditions of existence of adequate models are given. It is shown that the class of adequate models is infinite.

7730569/233419 Innovative technology of training engineers of underwater robotics and marine industry in Russia
# 10, October 2011 The author tells about scientific and methodological treatment and evaluates a large  very widespread abroad but almost unknown in our country  innovative educational project technology. The technology is based on a methodologically verified system of regional, national and international competitions, championships of student project teams – developers of hightech engineering systems. In the annual life cycle, the technique involves design of the system by students according to a particular task, making its prototype, testing its sample, demonstrating it in action, and a rating competition with similar design developments in physical modeling of extreme situations. Based on personal experience of a BMSTU professor  mentor of a student team, the author provides a wellreasoned proof that Russian students who know the basics of automated design technologies  CAD, CAM, CAE, CASE, CALS  and who have 3Dprinters are able to successfully compete with professional teams of top foreign universities.

Nigeria: "More Than Half of Nigerian Lecturers Don't Have a PHD"
# 10, October 2011 At least 61% of an estimated 35,000 lecturers in Nigeria are still on the lowest rung of academics, 'lecturer 1', according to the National Universities' Commission, which regulates university education in the country, writes JuddLeonard Okafor for the Daily Trust.Executive secretary of the NUC, Professor Julius Okojie, said "more than half [the number of lecturers in Nigerian universities] do not have a PhD". The figure is about 21,350.
SCOTLAND: Agricultural Colleges Plan Merger as "Rural University"
# 10, October 2011 A “RURAL university college for Scotland” is set to be created by the merger of four of the country’s further and higher education institutions.The Scottish Agricultural College (SAC) looks set to merge with three “landbased” colleges in a process which would affect thousands of students.Discussions about a possible merger were already under way between the SAC and both Elmwood College in Fife and Oatridge in West Lothian, but they have now been joined by Barony College in Dumfries.While all the colleges are likely to retain their regional bases, the move would lead to a reduction in the number of courses being duplicated across the four institutions.
UK: Number of European Students Soars by a Third in a Decade
# 10, October 2011 The number of students admitted to British universities from mainland Europe has soared by more than a third in the last 10 years, figures show. A record 125,000 students from European Union member states claimed places at higher education institutions last year – a rise of some 35,000 compared with a decade ago. The increase was around twice as fast as the rise in admissions among British students. Undergraduates from the EU are subsidised by the taxpayer and are eligible for the same lowinterest Government loans as those taken out by British counterparts.
FRANCE: Sarkozy's Reforms Herald French 'Ivy League'
# 10, October 2011 Radical plans to create a French "Ivy League" are gathering pace as the first winners of a new elite universities scheme worth €7.7 billion (£6.6 billion) start to receive cash. The Initiative d'Excellence (Idex) scheme is part of the biggest shakeup in French higher education for almost 40 years. It is designed to establish five to seven "worldclass" universities capable of competing internationally for the best students and academics.Driven by President Nicolas Sarkozy, the proposed "Sorbonne League" will require nonselective universities, the highly selective grandes écoles and France's independent research organisations, such as the National Centre for Scientific Research, to work together for the first time in exchange for investment.
Last of the free: will Norway's Universal Nofee Policy Endure?
# 10, October 2011 As Sweden introduces tuition fees of up to €15,000 (£13,145) for nonEuropean Union students this year, Norway is now one of the few European states to stick to the oncesacrosanct belief in "free education for all".While its Nordic neighbours Sweden and Denmark continue to provide free tuition for domestic and EU students only, Norway stands alone in offering free higher education to students regardless of citizenship.
UK: University College London will Scrap First Class Degrees to Combat Award Inflation
# 10, October 2011 University College London will stop telling students whether they have received a first, second or third, and instead given them an Americanstyle "grade point average". It gives students a score based on all the courses they have taken as undergraduates. The move comes after "award inflation" which has undermined the traditional undergraduate degree classification. Official figures showed almost twothirds of students gained a first or uppersecond class degree in 2010. Some 46,825 students – one in seven – were awarded first class degrees by UK universities, double the number a decade ago.

WALES: University of Wales, Newport to Set Out Plans for New Superinstitution for Southeast Wales
# 10, October 2011 A university mapped out its blueprint for a new superinstitution bringing together partners in southeast Wales. The University of Wales, Newport, talked of a new era for higher education in the region which would leave behind "any competition and rivalry that may have hampered collaboration in the past", writes Gareth Evans for the Western Mail.The new institution would be led by one vicechancellor and a single management team, but would maintain "locally focused brands and missions" for each of its constituent parts. It would be called the University of SouthEast Wales or South Wales Metropolitan University, with an addon specific to its location.
US: Princeton Adopts Open Access Policy
# 10, October 2011 The movement to make research freely available got a highprofile boost this week with the news that Princeton University’s faculty has unanimously adopted an openaccess policy. “The principle of open access is consistent with the fundamental purposes of scholarship,” said the faculty advisory committee that proposed the resolution.The decision puts the university in line with Harvard University, the Massachusetts Institute of Technology, and a growing number of other institutions with policies that encourage or require researchers to post open copies of their articles, usually in an institutional repository.
