Introduction: In previous work, we introduced the concept of the multimode coil [1]. The multimode coil consists of a tracking coil connected in series with a multi-turn imaging coil and simultaneously performs the functions of active tip tracking, imaging and inductively coupled wireless marker. The tracking and imaging coils have conflicting design requirements. While the region of sensitivit...

Buildings account for a large portion of the total energy use in US; therefore, improving operation typical variable-air-volume (VAV) systems buildings can provide tremendous economic opportunity. ASHRAE Guideline 36 recommends resetting strategy supply air temperature (SAT) VAV based on outside temperature. However, this may not produce optimal performance, particularly when simultaneous cooli...

In order to improve the thermal economic performance of coal-fired units in power industry, supercritical above 600MW generally adopt method installing external steam cooler system utilization reheat. view difficulties and problems calculating three extraction flow high pressure heater by traditional method, this paper, a new calculation medium at inlet is proposed based on fluid dynamics. This...

In this study, the design, numerical modelling, and construction of various Helmholtz pair coil systems were investigated to produce a homogeneous magnetic field. The field was simulated using three different including 2-coil, 3-coil, 4-coil combinations in order optimize homogeneity strength over region interest that consists cylindrical geometry with height 700 mm diameter 90 mm. created by s...

The Levitated Dipole Experiment (LDX) is an innovative approach to explore the magnetic confinement of a fusion plasma offering the possibility of an improved fusion power source. In this concept, a magnetic dipole (a superconducting solenoid) is magnetically levitated for several hours at the center of a 5 m diameter, 3 m tall vacuum chamber. The Floating coil (F-coil) is designed for a maximu...

Using a nearly monodisperse high molar mass poly(N-isopropylacrylamide) (PNIPAM) sample, we successfully made the conformation change of individual PNIPAM chains from a coil to a fully collapsed stable single chain globule in an extremely dilute aqueous solution, which enabled us to study for the first time the globule-to-coil transition of a single homopolymer chain in solution. A comparison t...

BACKGROUND AND PURPOSE Coil migration is a potentially serious complication of endovascular aneurysm treatment. The aim of the study was to systematically investigate the effectiveness of coil retrieval with a stent retriever in an animal model. MATERIALS AND METHODS A total of 148 coils of various types and sizes were placed into arteries of varying diameters in a porcine in vivo model. Coil...
