Thrust ripple and density greatly impact the performance of linear machine other actuators, causing positioning control precision, dynamic performance, efficiency issues. Generalized pole-pair combinations are difficult to satisfy both thrust for double salient reluctance machines. In this paper, a DC-Biased vernier (DCB-VRLM) is proposed solve abovementioned The key design reduce enhance with ...

2015 Since the introduction of plain old balloon angioplasty, there have been several improvements in the treatment of coronary artery disease, with the advent of bare metal stents and drug-eluting stents being two notable milestones. Although these stents confer better acute gains in coronary interventions, the risk of instent restenosis (ISR) remains, especially with bare metal stents. Hence,...

The primary objective of this work was to analyse the adequacy of the Double Cantilever Beam (DCB) test in determining fracture toughness under pure mode I loading of cortical bone tissue. A new data reduction scheme based on specimen compliance and the crack equivalent concept was used to overcome the difficulties inherent in crack monitoring during its growth. It provides a complete resistanc...

The objective of the current study was to evaluate the effect of biofield energy treatment on the isotopic abundance ratios of PM+1/PM, PM+2/PM, PM+3/PM and PM+4/PM in p-DCB using gas chromatography-mass spectrometry (GC-MS). The p-DCB was divided into two parts one part was control sample, and another part was considered as the treated sample which was subjected to biofield energy treatment (T...

Here we investigated how a coating of intravascular balloon with paclitaxel (drug-coated balloon; DCB, Freeway™) impacted porcine peripheral artery vascular function and remodeling. Domestic swine (n = 54) underwent percutaneous overstretch balloon dilation of femoral and iliac arteries, controlled by angiography and optical coherence tomography (OCT). Paclitaxel tissue uptake was measured at 1...

In recent decades, the outcomes of coronary heart disease (CHD) have markedly improved, which can be partly attributed to the use of novel drugs (especially statins and antiplatelet drugs) and partly to the evolution of percutaneous coronary intervention (PCI). From percutaneous transluminal coronary angioplasty to bare-metal stent and then to drug-eluting stent, every step of PCI is attractive...

Polyvinylpyrrolidone (PVP) is a conventionally applied hydrophilic lubricious coating on catheter-based cardiovascular devices, used in order to ease movement through the vasculature. Its use as drug reservoir and transfer agent on drug-coated balloons (DCB) is therefore extremely promising with regard to the simplification of its approval as a medical device. Here, we developed a PVP-based coa...

This paper describes a small range six-axis accelerometer (the measurement range of the sensor is ±g) with high sensitivity DCB (Double Cantilever Beam) elastic element. This sensor is developed based on a parallel mechanism because of the reliability. The accuracy of sensors is affected by its sensitivity characteristics. To improve the sensitivity, a DCB structure is applied as the elastic el...

Abstract Zhangbei Flexible DC Grid project with grid characteristics is different from the previous multi-terminal flexible project. uses a breaker (DCB) to isolate line faults. Limited by current domestic research and development level of high-voltage DCB, it does not have overload operation capacity. Against this problem that DCB endangers safety equipment system after permanent fault overhea...
