Basalt continuous fibers are regarded as an inert and naturally occurring material that is produced from basalt rock by using single component raw material and drawing and winding fibers from the melt. Basalt based materials are environmentally friendly and nonhazardous. Basalt FRP (BFRP) composites as a reinforcement not only display a higher strength and modulus, but also a similar cost, and ...

A purely functional model of computation, called Priority-based Functional Reactive Programming (P-FRP), has been introduced as a new paradigm for building real-time software. Unlike the classical preemptive model of real-time systems, preempted events in P-FRP are aborted and have to restart when higher priority events have completed, making the response time of events dependent on the executi...

در دهه 80 میلادی، پژوهشگرانی برای اولین بار در اروپا و آمریکا چسباندن کامپوزیت ها به بتن و سقف را آزمایش کردند. نتایج مثبت آزمایش ها جامعه علمی را تشویق کرد تا ستون ها و سایر قسمت های سازه را نیز با کامپوزیت ها پوشش داده و مورد مطالعه قرار دهند.پس از آن در ژاپن هم به زودی متوجه شدند که روش های مقاوم سازی می تواند در برابر زلزله های شدیدی که آن کشور را تهدید می کند، روش مناسبی باشد.امروزه مقاوم ...

Study the tensile damage and fracture behavior of FRP composite materials by the acoustic emission technology, broadband sensors record the acoustic emission signals when composite materials in the process of tensile damage at different fiber angle. The acoustic emission characteristics of FRP composite materials’ tensile damage was analyzed by 3D parameter methods. Analysis the amplitude of co...

برای تقویت ستونهای بتن آرمه، میتوان از پوششهای کامپوزیتی frp به دور ستون استفاده کرد. بیشترین کاربرد این پوششها به صورتی است که الیاف کامپوزیت کاملاً یا به صورت عمده در جهت عمود بر محور طولی ستون یا جهت حلقوی قرار گیرند. اما میتوان با استفاده از کامپوزیت frp با الیاف طولی نیز مقاومت ستون را افزایش داد. در صورتی که در تقویت ستون، از کامپوزیت با الیاف در راستای طولی استفاده شود، این کامپوزیت با تح...

To investigate the action of motilin on the sphincter of Oddi, the flow rate of the perfusate (FRP) discharged into the duodenal lumen through the orifice of the common bile duct was measured by means of an electric drop counter in decerebrated dogs. Motilin in doses above 0.5 micrograms/kg i.v. reduced or stopped the FRP. The fifty percent recovery time of FRP was 20 min and full recovery time...

In previous work we presented Functional Reactive Programming (FRP), a general framework for designing hybrid systems and developing domain-specific languages for related domains. FRP’s synchronous dataflow features, like event driven switching, supported by higherorder lazy functional abstractions of Haskell allows rapid development of modular and reusable specifications. In this paper, we wil...

The strengthening of concrete structures externally bonded with fiber reinforced polymer (FRP) sheet is increasingly being used for repair and rehabilitation of existing structures. This paper provides information in the area of long-term durability of FRP-concrete interface externally bonded with FRP composite sheet. It mainly discusses and summarizes the influence of harsh environmental expos...

In this paper a new parallel version of finding the Fuzzy Reasoning Path (FRP) using the knowledge representation model, introduced by Chandwani & Chaudhari [1] known as Fuzzy Deduction Graph (FDG) is presented. In an FDG, a systematic method of finding the Fuzzy Reasoning Path (FRP) already exists, which is based on Dijkstra's shortest path framework [2]. Our FRP algorithm is conglomerati...
