This paper presents the application of eXtreme Programming to the software agents research and development group at TRLabs Regina. The group had difficulties maintaining its identity due to a very rapid turnover and lack of strategic polarization. The application of eXtreme Programming resulted in a complete reorientation of the development culture, which now forms a continuous substrate in eve...

in recent years, interest in climatic extreme events (droughts, floods and heat waves) has been growing not only due to their direct impact on many socio-economic sectors, but also as climate change indicators. in this study, the behavior of extreme events is investigated using extreme climate index software (ecis) package. the trend analysis of extreme indices is applied to daily series of tem...

We suggest a principle for isolation of circularly polarized waves in magnetically active extreme-parameter metamaterials. Using theoretical analysis and numerical simulations, we show that metamaterials with extreme parameters, such as epsilon-near-zero materials (ENZ), when merged with magneto-optical materials, become transparent for forward circularly polarized waves of a given handedness a...

Extreme 4-dimensional dilaton black holes embedded into 10-dimensional geometry are shown to be dual to the gravitational waves in string theory. The corresponding gravitational waves are the generalization of pp-fronted waves, called supersymmetric string waves. They are given by Brinkmann metric and the twoform field, without a dilaton. The non-diagonal part of the metric of the dual partner ...

We study the gravitational waves in the 10-dimensional target space of the superstring theory. Some of these waves have unbroken supersymmetries. They consist of Brinkmann metric and of a 2-form field. Sigma-model duality is applied to such waves. The corresponding solutions we call dual partners of gravitational waves, or dual waves. Some of these dual waves upon Kaluza-Klein dimensional reduc...
