Neutral point inverter controller using H infinity techniques by M. Alsharif, Ali Omar

“…This can be achieved by using a neutral-point circuit that consists of a conventional neutral leg and a split dc link. In this project, a H infinity (H∞ ) current controller is proposed to force the current flowing through the split dc link to be nearly zero so that the neutral-point current is stable, and then, a current control loop is added to eliminate the imbalance of the current so that the neutral-point current is balanced with respect to the dc terminals. …”

European sovereignty between autonomy and dependence: a guide for EU policy by Chryssogelos, Angelos

“…But today its relevance appears uncertain in the face of Russia’s invasion of Ukraine and the growing assertiveness of China. This brief argues that European sovereignty (and related concepts such as strategic autonomy) is still an important and necessary guide for EU policy, but only if it is dissociated from some of the excessive and overambitious definitions given to the concept when it was first developed.…”

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. …”
