Design of microstrip ultra wide band antenna with two notch filters for wireless communication by Abdulhasan, Raed Abdulkareem

“…In order to add reconfigurable characteristics to the patch antenna, two copper strips are putted on the slots to represent the ON and OFF switching status of an ideal Pin diode. By using this simple switching technique, the current distribution of the patch changes and enables the antenna to have four modes of operation. …”

Futurism: performance and performativity of a movement by Scarso, Jacek Ludwig

“…Performance interventions span across the history of this movement (Goldberg, 2011): from the notorious 'serate' instigated by Marinetti, in which the audience would be purposefully scandalised, provoked and offended, to the futurist music concerts that provided an ancestral root for the aesthetics of synthesised sound in contemporary music (Rodney, 1976), not to mention the Russian counterpart of this movement, which embraced, on stage, such wide a field as to encompass theatre, opera, dance, music and scenic design. …”
