A simple and reliable inverter is a prerequisite for realizing an efficient active power filter. This paper presents a reduced switch count (RSC) based asymmetrical switched dc sources inverterfor a threephase three-wire (3P3W)shunt active power filter (SAPF). The performance of considered RSCtopology is studied on seven-level asymmetrical configuration with simple level-shifted pulsewidth modu...

Percutaneous coronary interventions (PCIs) are relatively safe, and the complication rate is low in comparison to cardiac surgery revascularization. The incidence of broken or retained PCI equipment is about 0.1–0.8% [1]. We report a successful retrieval of a fractured guide wire by using a percutaneous catheter Amplatz GooseNeck Snare and Microsnare Kit (Covidien, Plymouth, USA), which was com...

Starting materials used were 99.8% pure nickel, 99.9% pure iron, 99.9% pure tantalum, and 99.9% pure molybdenum. The materials in a total weight of 500g were melted with a high-frequency induction furnace in vacuum. The melt was poured into an iron mold with an opening of 20mm diameter and 150mm length. After forging, the ingot was reduced to a thin plate 0.3mm in thickness by rolling and a wir...
