Analytical – theoretical study on SWTs in terms of pre-selection of the aero layouts best suited for further optimization
The development trend of the aero-engine control system is the distributed control system (DCS), and the communication among devices is the key point and difficult point of DCS. In this article, the communication interface of CAN (Controller Area Network) bus is designed, the CAN communication technology among nodes is studied, the semi-physical platform of DCS is established, and the semi-phys...
Tracheal stenosis caused by malignancy is a life-threatening complication. We performed stent therapy in two patients using the AERO™ stent, launched in late 2016 in Japan. One patient presented with stenosis of the trachea due to adenoid cystic carcinoma and the other with stenosis of the trachea due to esophageal cancer. Both patients showed improved symptoms, and no complications were identi...
A software tool for the prediction of the aero-thermodynamic environments of conceptual aerospace configurations is presented. The vehicle geometry is defined using unstructured, triangulated surface meshes. For subsonic Mach numbers a fast, unstructured, multi-pole panel code is coupled with a streamline tracing formulation to define the viscous surface solution. For supersonic and hypersonic ...
Most of the materials used in the industry of aero-engine components generally consist of titanium alloys. Advanced materials, because of their excellent combination of high specific strength, light weight and general corrosion resistance. In fact, chemical wear resistance of aero-engine alloy provides a serious challenge for cutting tool material during the machining process. The reduction in ...
background: aeromonas spp. can cause diarrhea and various infections in humans. access to rapid techniques with a high sensitivity and specificity is strongly needed for the identification of aeromonas species. the aim of this study was to evaluate two different methods including api 20e bacterial identification tests and the molecular detection using pcr primers specific for 16s-rrna and 23s-...

در این پژوهش، امکان بازیابی انتخابی روی از باطله های پرعیار دپو شده در معدن سرب و روی کوشک به روش شناورسازی، بررسی شد. دو مشخصه ی بارز این نمونه افزون بر درصد بالای اسفالریت، درصد بسیار زیاد پیریت (حدود 50%) و حضور مواد کربندار بود؛ از این رو رقابت بین کانی های اسفالریت و پیریت و جدایش انتخابی در فرایند شناورسازی دارای اهمیت بود. نتیجههای به دست آمده از شناورسازی آزمایشگاهی با...
