In this paper, a frequency switchable antenna design using genetic algorithms (GAs) for dual band WiMAX (3.5GHz) and WLAN (5.2GHz) applications is proposed.The area of the radiating patch element is divided into 2 mm square cells, with each cell assigned a conducting or non-conducting Ads characteristic.To realize frequency reconfiguration, switche

Cystic pancreatic neuroendocrine tumor accounts for 13-17% of pancreatic neuroendocrine tumors and 9-10% of resected cystic tumors.This unusual variant can make clinical diagnosis particularly challenging.A 28-year-old female patient presented with abdominal pain and dyspepsia.General and physical examination was unremarkable.On computed tomography

Due to the mismatch between transmit waveforms and receive filters, Cross-Ambiguity Function (CAF) shaping plays an important role in the design of cognitive radar waveforms and allows more freedom for waveform optimization problem than conventional ambiguity function shaping.A CAF shaping method is proposed for designing phase-shift keying transmi

The authors reflect on recent experiences at UN-Habitat and other international organizations to rethink stripper-pole the roles of planning towards larger development goals and to reform planning systems in places most in need of them.They consider the difficulties but ultimate necessity to learn from a variety of contexts and experiences to artic
