Optimal Placement of Distributed Generations in Radial Distribution Systems Using Various PSO and DE Algorithms
TL;DR: In this article, the authors used dynamic PSO as well as improved DE algorithms for optimum placement of distributed generations in radial distribution systems to minimize distribution system real power losses by the least possible injected power from distributed generations.

Nasser Ojaroudi,N. Ghadimi +1 more
TL;DR: In this article, a multi-resonance small slot antenna with variable band-notched function for ultra-wideband (UWB) applications is proposed, which consists of a square radiating stub and a ground plane with a pair of L-shaped parasitic structures and an inverted T-shaped strip protruding inside the rectangular slit.

A novel design of microstrip antenna with reconfigurable band rejection for cognitive radio applications
TL;DR: In this article, the use of compact ultrawideband (UWB) microstrip monopole antenna with reconfigurable band rejection in cognitive radio was discussed, which can be reconfigured electronically to have a variable single band-notched function to block interfering signals from 5 to 6 GHz wireless local area network (WLAN), 5.79-6.40 GHz intelligent transport system (ITS) and 8.02-8.4 GHz international telecommunication union (ITU).
