consideration of the current-voltage (i-v) characteristics variations of solar modules with temperature and irradiations variations is basic for maximum power point tracking (mppt). having a simple and accurate mathematical model for the optimize utilization of the solar modules is essential. in this paper, a novel modeling of photovoltaic systems with novel coefficients is proposed for mathema...

the purpose of this paper was to see whether any significant relationship exists among efl learners’autonomy, left/right brain dominance, and reading comprehension of the academic reading and generalreading modules of ielts examination. to this end, 100 female efl learners were randomly selectedfrom those who were attending ielts preparatory courses at a language school in tehran. allparticipan...

we call a module  essentially retractable if homr for all essential submodules n of m. for a right fbn ring r, it is shown that: (i)  a non-zero module  is retractable (in the sense that homr for all non-zero ) if and only if certain factor modules of m are essentially retractable nonsingular modules over r modulo their annihilators. (ii)  a non-zero module  is essentially retractable if and on...

Programming languages are in a continuous state of flux in order to keep up with emerging needs of programmers. They are grown with new constructs so that programmers can express the problems from their domain within the language they are using. Growing languages means to grow their implementations along with them. To support this, we wish to preserve the decomposition of languages into languag...

Wildfire emissions in the boreal forests yield an important contribution to the chemical budget of the troposphere. To assess the contribution of wildfire to the emissions of atmospheric trace species in the Great Xing’an Mountains (GXM), which is also the most severe fire-prone boreal forest region in China, we estimated various wildfire activities by combining explicit spatio-temporal remote ...

Authentication is a process by which both the sender and receiver check and identify the validcommunicative partners prior to initialization of message exchange. Authentication is a security module which is defined at the time of starting of communication between the two communicating entities such as client and server due to the unlimited amount of insecure and malicious intruders it becomes s...

Q-modules are internally-clocked modules that can be used to satisfy delay-insensitive specifications. The allowed changes of inputs to, and outputs from, a delay-insensitive module are specified by partial orderings of these signals in such a way that the set of possible behaviors remains unchanged with arbitrary values of delay inserted in series with each input and output path. A two-phase s...
