Functional reactive programming facilitates programming with time-varying data that can be perceived as streams flowing through time. Thus, one can think of FRP as an inversion of flow control from the structure of the program to the structure of the data itself. In a typical (say, imperative) program, the structure of the program governs how the program will behave over time; as time moves for...

Saito et al. (Modern Plastics 1997;74:175-7) have developed a low-cost transtibial prosthesis made of fiber-reinforced plastic (FRP). The prosthesis is comprised of an aluminum pylon, a cosmetic cover, and a constant cross-section composite foot into which aluminum supports are screwed to increase load-bearing capacity. Replacing these supports with a single integrated FRP stiffener significant...

We describe a language-centric approach to solving the complex, low-level, and error-prone problem of network control. Specifically, we have designed a domain-specific language called Nettle, embedded in Haskell, that allows programming OpenFlow networks in an elegant, declarative style. Nettle is based on the principles of functional reactive programming (FRP), and as such has both continuous ...

Fine roots (FR) play a major role in the water and nutrient uptake of plants and contribute significantly to the carbon and nutrient cycles of ecosystems through their annual production and turnover. FR growth dynamics were studied to understand the endogenous and exogenous factors driving these processes in a 14-year-old plantation of rubber trees located in eastern Thailand. FR dynamics were ...

Socio-economic status is a major indicator of livelihood and the two crucial factors determining livelihood are poverty and income inequality. The present study assessed the livelihood status of fishermen operating fibre re-inforced plastic (FRP) boats (motorised) of 9-10 m LOA. Socio-economic status, including poverty and income inequality of fishermen, comprising both owners (FRPO) and labour...

Synopsis: Advantages such as light weight, high mechanical properties and resistance to aggressive and chemical agents, non invasive installation, low tooling and machinery costs, possibility to repair the structure without interrupting its use have determined great expectation on Fiber Reinforced Polymer (FRP) composites for the strengthening of civil structures. However, their diffusion is of...

In recent decades, the application of fibre-reinforced polymer (FRP) composites for strengthening structural elements has become an efficient option to meet the increased cyclic loads or repair due to corrosion or fatigue cracking. Hence, the objective of this study is to explore the existing FRP reinforcing techniques to care for fatigue damaged structural steel elements. This study covers the...

We have developed a domain speci c language for the construction of robot controllers, Frob (Functional ROBotics). The semantic basis for Frob is Functional Reactive Programming, or simply FRP, a purely functional model of continuous time, interactive systems. FRP is built around two basic abstractions: behaviors, values de ned continuously in time, and events, discrete occurances in time. On t...

طیف گامای آنی تولید شده حین تابش پروتون به بافت، برای آنالیز عنصری بافت تحت درمان کار گرفته می‌­شود. هدف اصلی این در پروتون­درمانی ردیابی غلظت اکسیژن تومور است. پایش برخط تغییر عنصر پزشک را سمت ارزیابی روند بهبود و تخمین پاسخ بدن بیمار هدایت می‌­کند. مطالعه گاما یک فانتوم چشم انسان آشکارساز HPGe با استفاده از ابزار Geant4 شبیه‌سازی ­کارگیری شبکه عصبی انجام شد. 33 نمونه حاوی تومورهای متفاوت نظر ...
