abstractacquiring vocabulary, as a significant and challenging part of language learning process, has always been consistent with reading. in this study, the researchers examined the effect of enhanced extensive reading on efl learners’ incidental acquisition of english vocabulary, with specific focus on phrasal verbs. twenty five homogenized participants were selected and divided into two grou...

In this paper, an efficient blind equalization with two-stage single/multilevel modulus and decision directed (DD) least mean square (LMS)-like algorithm is proposed for high-order QAM (64/256/1024QAM) cable modem systems. In wire-lined cable systems, it seems that the cable channel may display a nearly invariant multi-path effect over a considerable time, and then the blind equalizer can have ...

In this paper, we study the convergence behavior of the coexistence between multiple cognitive tactical radio networks. Each tactical radio network has one transmitter which broadcasts a common information to several receivers sharing the same parallel sub-channels and updates its power allocation autonomously from the other networks owing to a distributed dynamic spectrum management function b...

Abstract: This paper presents a nonlinear controller for uncertain single-input–single-output (SISO) nonlinear systems. The adopted approach is based on the feedback linearization strategy and enhanced by a fuzzy inference algorithm to cope with modeling inaccuracies and external disturbances that can arise. The boundedness and convergence properties of the tracking error vector are analyticall...

The diurnal cycle of the North American monsoon is analyzed based on the output from a mesoscale model simulation. Statistically significant diurnal cycle in precipitation is identified, with heavy precipitation—essentially convective—dominating in local afternoons. Temporal evolution of key parameters in relation to precipitation is investigated, based on which a sequence of the dynamic/thermo...

An Enhanced Two-Step Least Squared (LS) approach is proposed here for hybrid Time Difference of Arrival/Angle of Arrival (TDOA/ AOA) wireless location. Compared to the original two-step LS algorithm, the method here can provide better performance, almost the same as that of Taylor-Series estimator. Compared to the Taylor-Series solution, the method has many computational advantages, such as, li...

The evolutionary strategy search (ESS) algorithm is a novel method for implementing fast block motion estimation (ME) using evolutionary strategy (ES). ESS uses a combination of ideas based on existing search strategies and employs a novel (1þ sl) ES implementation. It is essentially a succession of random searches, but by controlling the placement and distribution of these searches in a simple...

A modified formulation of Maxwell's equations is presented that includes a complex and nonlinear coordinate transform along one or two Cartesian coordinates. The added degrees of freedom in the modified Maxwell's equations allow one to map an infinite space to a finite space and to specify graded perfectly matched absorbing boundaries that allow the outgoing wave condition to be satisfied. The ...
