The paper is dedicated to an approximation of a set of attainability for type “trunk” multisectional robot-manipulator. SPSO method was developed and used for the task resolution. SPSO is based on well-known MOPSO method that is used for multi-objective optimization task. SPSO method as well as MOPSO method implements one of the version of particle swarm optimization method (PSO) that is often used for global optimization tasks. Sigma-algorithm is used for finding non-dominated solutions. SPSO effectiveness is demonstrated for several tasks of a set of attainability search for both with and without obstacles.
Temperature calibration of a strapdown inertial navigation system based on MEMS sensors
# 01, January 2011
D.B. Pazychev
The inertial sensor signals caused by the temperature changing are very difficult to determinate. To observe the errors, this paper presents an error model of MEMS sensors. The error model consists of the arrays of the coefficients defined for each navigation system sensor. Processing sensor signals, I show how to calculate the parameters of the error model during the temperature changing. The method uses the least square method adapted by an increment of the temperature. This adaptation provides the calculation of the coefficients without influencing of the sensor temperature not changing during the calibration. Navigation system CompaNav2 based on ADXRS300 and ADXL210 Analog Devices sensors was calibrated using the method. The calibration results demonstrate that the method provides a practical and accurate technique for calibrating a strapdown inertial navigation systems based on MEMS sensors

# 01, January 2011
More and more US universities are apparently giving up on Japan as a target for recruiting students, as a survey showed that the number of US universities taking part in publicity events in Japan has sharply dropped in recent years, reports Yuji Yoshikata for The Daily Yomiuri.Japanese students used to be the largest group among foreign students at US universities. But their number is now far below that of Chinese students.

CHINA: Hong Kong's Universities Decide Bigger Is Better
# 01, January 2011
Universities in Hong Kong are counting down towards one of the most significant transformations ever attempted in the territory's higher education sector, and the logistics are daunting: thousands of extra students, hundreds of new lecturers, realms of new curricula to write and hours of additional courses to fill, writes Liz Gooch for The New York Times.At a time when universities in many Western countries are pinching budgets, Hong Kong's are gearing up for a massive expansion of the undergraduate population: starting in the 2012 academic year, all Hong Kong undergraduate degrees will be extended from three years to four.
UK: Top companies 'recruiting staff directly from school'
# 01, January 2011
More companies are recruiting staff directly from school amid fears bright teenagers are turning their backs on university, according to research.A report published today found that growing numbers of top employers are targeting school leavers instead of limiting vacancies to applicants with a degree. The disclosure, in a study by the Association of Graduate Recruiters, follows claims that thousands of talented teenagers are shunning higher education because of rising student debt and mounting competition for university places. According to figures, more than a quarter of leading businesses now employ staff directly from schools and colleges and a fifth of remaining firms are considering opening up recruitment schemes to this age group.
Visa restrictions will damage growth of UK business schools
# 01, January 2011
UK government plans to restrict the number of students entering the UK, and restricting employment visas for graduates, could be damaging to the growing popularity of UK graduate business degrees, according to GMAC, the the US-based Graduate Management Admissions Council, which administers the GMAT test.Though the past five years has seen business schools in Europe become an increasingly popular destination for international students choosing to study an MBA, this growth could be curtailed if potential UK students cannot get visas, says Julia Tyler, executive vice-president of GMAC.
SCOTLAND: University fears over tough new visa rules
# 01, January 2011
Universities warn that Scotland will have one of the most restrictive visa regimes in the world for overseas students under UK government plans to crack down on immigration, writes Andrew Denholm for Herald Scotland. Universities Scotland, which represents university principals, argues the proposals will make visa conditions here tougher than those of countries such as America, Canada, Australia and Germany, which are in direct competition for students. The organisation has written to all MPs calling for support for a separate immigration policy for Scotland.
INDIA: Women engineering student numbers soar
# 01, January 2011
Women have more than doubled their number across the country's engineering colleges over the past decade, pushing against one of the most resilient glass ceilings in Indian academia. Latest University Grants Commission (UGC) statistics show that a total of 276,806 women were enrolled in engineering and technology courses at the start of the 2009-10 academic session as compared with 124,606 in 2000-01.
