This study presents the integrated control/structure design of a large flexible structure, the Extra Long Mast Observatory (ELMO). The integrated design is performed using structuredH∞ control tools, developing the Two-Input Two-Output Port (TITOP) model of the flexible multi-body structure and imposing integrated design specifications as H∞ constraints. The integrated control/structure design ...

In this paper, we present a switch based on coupling and resonance in thegraphene plate and rings operating at 10 THz. This structure consists of several layers ofHexagonal Boron Nitride (hBN), SiO2 and P+Si, such that graphene plates and rings areinside the hBN layer. The terahertz wave is incident from the upper part of the switchand Surface Plasmons (SPs) are excited ...

Concentrations of lead, copper, cadmium, and mercury were determined in sediments and two selected marine organisms (Cynoglossus arel and Panulirus homarus) collected from Jask Port, Darak Port, Pozm Port, Gulf of Chabahar and Gowatr Port in the north coasts of the Oman Sea during pre (spring) and post (autumn) monsoon in 2017. Heavy metals concentrations were determined by atomic absorption sp...

Implantable ports are used for intravenous infusion therapy and play an important role in management of oncology patients. These ports are best suited for patients requiring long-term therapy (>4 weeks). Implanted ports provide reliable venous access protect peripheral access increase patients’ comfort through reducing repeated and difficult vein punctures allow for safe and comfortable admi...
