Inverted ‘V–Y’ advancement medial epicanthoplasty
Journal of Plastic, Reconstructive & Aesthetic Surgery, 2012The presence of an epicanthal fold is a distinctive anatomic feature of the Asian population. Epicanthoplasty can be very helpful in resolving the above problematic anatomy and may produce a more aesthetic appearance. The goal of this report is to describe a modification in the traditional operative methods related to medial epicanthoplasty, to ...

An advanced control method of inverters in Microgrid
2011 International Conference on Advanced Power System Automation and Protection, 2011In this paper, it is discussed from the aspects of the operation requirements in Microgrid and the control methods in power system, focusing on the idea of how to make the inverter imitate the output characteristics of the synchronous generator. The fundamental difference between Microgrid and the power grid lies in the hardware interface, one is the ...

An advanced photovoltaic system based on the fifteen-Level PUC inverter
2015 IEEE 24th International Symposium on Industrial Electronics (ISIE), 2015In this paper, authors propose an advanced photovoltaic system based on the 15-Level PUC inverter. The proposed inverter has the advantage to operate with a single PV array while generating fifteen voltage levels. Even it is constituted from only eight switches and two capacitors; it can nevertheless offer a fifteen-level output voltage.
