abstract purpose: initially, reading challenges related to the web environment will be discussed in the current paper followed by describing four reading modes including exegetical, dogmatic, agnostic and dialectical which have been proposed by walter kaufman. the research aimed to examine such modes of reading in the web environment via a questionnaire distributed among the postgraduate studen...

In this paper, we propose three advanced digital predictive current-mode control (DPCC) algorithms based on a simplified estimation method of duty cycle lost time for asymmetric half-bridge (AHB) LED constant-current driver. They are the peak current mode control(DPPCC) algorithm leading-edge modulation, quasi-valley control(DPqVCC) trailing-edge and quasi-average control(DPqACC) double-edge mo...

This research paper contains a new electronically tunable current-mode biquadratic universal filter using a new active building block; current controlled differential difference current conveyor transconductance amplifier (CCDDCCTA). The proposed filter provides the following important and desirable features: (i) One can use only one CCDDCCTA and two capacitors; (ii) One can get low pass (LP), ...

In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...
