فومهای میکروسلولی (Microcellular Foams) به آن دسته از فومها اطلاق میشود که دارای تعداد بسیاری سلولهای ریز در اندازه های حدود 10 میکرون میباشند. در این فومها از گاز خنثی (نیتروژن یا دی اکسید کربن) بعنوان ماده پف دهنده استفاده میشود. بدلیل کوچکی سلولهای این فومها خواص مکانیکی و فیزیکی برتری (مانند: استحکام خستگی، استحکام به ضربه ، خواص حرارتی و دی الکتریکی) حتی نسبت به پلاستیک فوم نشده دارند. ...
فرضیه: بهدلیل ماهیت مدلسازی لایهنشانی همجوش (FDM) که در آن قطعهها بهشکل لایهلایه ساخته میشوند، محصولات حین فرایند چاپ مستعد نقصهای بسیاری هستند. بنابراین، برای بهحداقلرساندن نقصها و سایر کاستیها به راهحلهای کارآمدی نیاز است. افزایش خواص فیزیکی و مکانیکی قطعههای ساختهشده با استفاده از نانوذرات یکی از این روشهاست.روشها: بهمنظور بهبود خواص مکانیکی آکریلونیتریل-بوتادیان-اس...
Practical high-quality speech and voice synthesis using fixed frame rate ABS/OLA sinusoidal modeling
This paper describes algorithms developed to apply the Analysis-by-Synthesis/Overlap-Add (ABS/OLA) sinusoidal modeling system to real-time speech and singing voice synthesis. As originally proposed, the ABS/OLA system is limited to unidirectional timescaling, and relies on variable frame length to accomplish time-scale modification. For speech and voice synthesis applications, unidirectional ti...
Autoantibodies are characteristic features of autoimmune diseases (Table 1). In organ or tissue-specific autoimmune diseases, autoantibodies against cell-surface molecules are usually observed. These antibodies (Abs) stimulate or damage the target cells and cause organor tissue-specific diseases. In systemic autoimmune diseases, in addition to anti-cellsurface molecule Abs, Abs against intracel...
Broadly neutralizing Abs to HIV-1 are well described; however, identification of Ags that elicit these Abs has proven difficult. Persistent infection with GB virus type C (GBV-C) is associated with prolonged survival in HIV-1-infected individuals, and among those without HIV-1 viremia, the presence of Ab to GBV-C glycoprotein E2 is also associated with survival. GBV-C E2 protein inhibits HIV-1 ...
Anti-lock braking system (ABS) is the most common safety system in the vehicles, which works to increase the generated braking force between the tire and the road surface for enhancing passenger safety specifically related to accident avoidance. However, designing an ABS is a challenging task considering the fact that it is highly nonlinear and a time varying system. The interaction between the...
ethylene bis-stearamide is one of the important acrylonitrile-butadiene-styrene ()abs)( polymer additives, which is used as lubricant, slip agent and mold release agent. in this research, ethylene bis-stearamide for abs application was synthesized using stearic acid and ethylene diamine under reflux condition. refluxing prevented ethylenediamine from evaporation and thus the initial molar ratio...
Antiphospholipid syndrome (APS) is a systemic autoimmune disease characterized by recurrent thrombosis and fetal loss in the presence of persistently positive antiphospholipid (aPL) antibodies (Abs) including lupus anticoagulant (LAC), IgG/IgM anticardiolipin (aCL) Abs and anti-b2glycoprotein I (b 2 GPI) Abs [1–3]. aPL Abs are a heterogenous group of autoantibodies that react to phospholipids (...

IoT (Internet of things) devices often collect data and store the in cloud for sharing further processing; This collection, sharing, processing will inevitably encounter secure access authentication issues. Attribute based signature (ABS), which utilizes signer’s attributes to generate private keys, plays a competent role identity privacy preservation. In ABS, there are multiple authorities tha...
