: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولComparative Performance Analysis of MPSK and MQAM-Modulation Parameters on Orthogonal Frequency Division Multiplexing (OFDM) System over Flat and Frequency Selective Rayleigh Fading Channels with Doppler Frequency
OFDM is a multicarrier modulation technology which has efficient spectrum utilization to support the transmission of high data rates. The typical subcarrier modulation schemes used in orthogonal frequency division multiplexing (OFDM) system includes: b inary phase shift keying (BPSK), phase shift keying (PSK) and quadrature amplitude modulation (QAM). This paper analyses the comparative perform...
متن کاملResearch on Measurement System of High-Frequency Parameters for Line Traps
The composing of high frequency line trap of power system is briefly introduced, A new method based on improved voltage meter method is presented, which can measure the frequency-impedance characteristic of the line trap of power system. A new testing arithmetic is presented based on the correlation principle, Cross-correlation functions of the two measured signals are directly computed and som...
