Advances in wireless communication place an increasing number of demands on antenna performance, necessitating the presence various capabilities a single device. Reconfigurable antennas are frequently utilized to meet these application within restricted area. The purpose this book chapter is summarize general introduction about hard ferrites, different synthesis methods ferrite for and altering...

To date, we know only a few handcrafted quantified Boolean formulas (QBFs) that are hard for central QBF resolution systems such as Q-Res and QU-Res, one specific family to separate QU-Res. Here provide general method construct The construction uses simple propositional (e.g. minimally unsatisfiable formulas) in combination with easy gadgets (Σb2 without constant winning strategies). This leads...

the third order term in the density functional is required for study of an inhomogeneous fluid. this term can be chosen such that, the thermodynamic potential gives the correct bulk pressure. the density porofile of a hard sphere fluid near hard wall which is an inhomogeneous fluid is obtained and it is shown that, if the third order term is ignored, although an exact bulk direct correlation fu...
