The H2 norm has been widely employed in controller design as an e ective measure on the performance of a system particularly when spectral information is available on exogenous disturbances. The `1 norm provides a measure on the performance of the system to persistent magnitude bounded disturbances. The `1 norm also provides stability margins with respect to uncertainty in the system. Optimal c...

Studying Jone’s polynomials in node theories, their generalization and their connections with ”vertex models” in two-dimensional statistical mechanics, Witten presents Hoph algebra deformations of the universal enveloping algebra su(2). There is a family of associative algebras depending on a real parameter p. These algebras are given by the generators E0, E+, E− and relations [2]: pE0E+ − 1 p ...

The Chekanov-Eliashberg DGA is a powerful tool for helping us to decide if two Legendrian knots are Legendrian isotopic. However, computing it can be an extremely tedious task. FrontLeg is a program created to automate these calculations. In this paper, we examine the algorithm for constructing the DGA and its Poincaré polynomials. We also describe the design, structure and functionalities of F...

I highlight results from Chandra observations of nearby galaxies , including the Milky Way. These observations have offered insights into old mysteries and indications of new high energy astrophysical phenomena and processes that are yet to be understood.

MOTIVATION spacodiR is a cross-platform package, written for the R environment, for studying partitioning of diversity among natural communities in space and time. Complementing and extending existing software, spacodiR allows for hypothesis testing and parameter estimation in studying spatial structuring of species-, phylogenetic- and trait diversities. AVAILABILITY Integrated with other sof...

Between February 14 th and 16 th of 2013, some sixty scholars from a wide variety of disciplines includ-finance, and accounting came to Austin, Texas to exchange ideas about the language of institutions. Most of them had never met before and many had nothing in common except one thing – they had used the same computer program to do their work. The software they used, DICTION (www.dictionsoftwar...

background mycobacterium tuberculosis is a vicious microbe co-existing with the infected host. this pathogen exploited opportunities to spread during periods of urbanization and social upheaval, and got retreated with improved hygiene. objectives this investigation was designed to clone and characterize m. tuberculosis mutt gene, a homologue of a dna repair protein in escherichia coli. the aim ...

tarikh-e jahangosha is the most important work about kharazmshahian and the mongols. utilising imagery, rhetoric, abundant persian and arabic poems, quranic verses and traditions, and proverbs have caused the prose to resemble poetry, fading its historical goals. here, quoting verses from the mythological parts of shahnameh, rostam and sohrab stories (37verses), and rostam and esfandiar (26 ver...
