E.M. Voronov, T.Yu. Karabahina, Syan'czyan' Chjan, N.G. Ahmetgaryaev
The problem of conflict-optimum counteraction of small groups of aircrafts in the form of two-stage procedure of ranking-allocation and conflict optimization by Nash for obtaining the stable-effective decision in the shape of matrix of conflict-optimum target setting is considered. Calculating time in the case of the exhaustive search is far from real-time, therefore the procedure of thinning of the counteraction effectiveness matrix is proposed, as a result the operating speed for the problem of counteraction of 4-by-4 aircrafts is rising twenty-fold.

# 08, August 2011
M.F. Menyaev
The paper considers the possibility of classification of organizational and technological decisions on the following levels: 1) accounting system of data processing, 2) complex systems of information processing; 3) the integrated information system; ( 4) dynamic control systems. It is shown that the accounting system, will allow to show the result of a major business and financial operations. The decision of complex level focused on the operation of the control loop "planning - accounting - control - analysis" in the complex. Integrated control systems of the enterprise allow to generalize the assessment of the state of processes of management of all resources of the company. WITH the help of dynamic technological-organizational structures are formed control systems with distributed in time and space resources.

77-30569/347058 Static algorithm of control of a suspension bracket of multi-wheeled vehicles: the automated overcoming of the escarp
# 08, August 2011
M.M. Jileikin
Increasing of requirements on average speeds of movement, under all other equal conditions, demands permanent improvement of suspension system of multi-wheeled vehicles (MWV), suspension bracket creation as a difficult mechatronic system. The traditional design of a suspension bracket of wheels can't resolve the contradiction set in the technical project on the MWV – maintenance of high average speeds of movement on road and district and mobility in the case of overcoming of large individual roughnesses. The algorithm of the automated overcoming of the escarp was developed, allowing to reduce loadings on bearing system of the MWV and corners of a longitudinal list of the case that promoted traffic safety increase. The results of simulation allowing to visualize the process of moving across the escarp by wheel car 8х8 were included in the article.

SWEDEN: Stockholm University Invests in International Students
# 08, August 2011
Stockholm University is not only one of the largest universities in Scandinavia, with around 50,000 students, but is also generally ranked among the top 100 universities worldwide. That makes it a great choice for prospective students in search of a vibrant and diverse study environment.The institution has recently made great strides in its efforts to further international cooperation, in a bid to remain at the forefront of internationalization of the higher education sector.Earlier this year, Stockholm University's board voted to set aside 38 million kronor ($6 million) for increasing international research cooperation and recruiting overseas students. The cash will be made available in 2012 and 2013 but the internationalization investment, known as Stockholm University Academic Initiative, is already well underway.The investment will also finance visits from prominent guest lecturers, research trips, as well as ambassadorship activities, aimed at increasing connections between Stockholm University and other participating institutions.

UK: Postgraduates 'Priced out of the Market' by Sharp Fee Increases
# 08, August 2011
Universities are raising their fees for home and European Union postgraduate students sharply, a survey suggests, prompting warnings about access to academia and other professions.The National Survey of UK Tuition Fees, for the coming 2011-12 academic year, indicates that rises in taught postgraduate fees for home and EU students outstrip increases for non-EU postgraduates and undergraduates.Based on data gathered from 147 UK higher education institutions, the fees survey shows that taught home/EU postgraduate fees range from £3,400 to £31,738.
