It is well known that the Boussinesq equation is the bidirectional equivalent of the celebrated Korteweg-de Vries equation. Here we consider Boussinesq-type versions of two classical unidirectional integrable equations. A procedure is presented for deriving multisoliton solutions of one of these equations – a bidirectional Kaup–Kupershmidt equation. These solitons have the unusual property that...

The auxiliary switch control using a neuro fuzzy technique is proposed to enhance the efficiency of bidirectional converter used in electric vehicle which performs soft switching. Continuous current data are difficult to obtain during a resonant operation due to limit of DSP ADC capacity. The auxiliary switch control has a lookup table reference of the turn on time. The ANFIS controller properl...

This paper proposes a new isolated CLLC resonant converter for automotive charging and discharging applications. The input includes full-bridge structure, the output battery side involves six switches to realize rectification function. On basis of component loss stress, this compares analyzes three battery-side structures: full-bridge, dual (eight switches), proposed six-switch bridge architect...

A 2x2 optical switch performing bidirectional cross-bar on optical communication signals at 1550 nm is presented and experimented. The switch is based on electro-optic effect in bulk CdTe crystals. Operation is totally independent by input state of polarization of the optical beams to be addressed. The proposed free-space architecture grants high compactness, reliability and fast responce time ...

Abstract— This paper proposes a new type of converter called Single Phase Z-source Matrix Converter (SPZMC). The SPZMC is an ac-to-ac converter device. Simulated using diode bridge bidirectional switch cell. The simulation is performed in different loads with fixed input and variable output frequency. Pulse Width Modulation (PWM) switching strategy is used to obtain the variable frequency. The ...

Class switch recombination (CSR) occurs between highly repetitive sequences called switch (S) regions and is initiated by activation-induced cytidine deaminase (AID). CSR is preceded by a bidirectional transcription of S regions but the relative importance of sense and antisense transcription for CSR in vivo is unknown. We generated three mouse lines in which we attempted a premature terminatio...

Abstract—In this paper, a high-conversion-ratio bidirectional dc–dc converter with coupled inductor is proposed. In the boost mode, two capacitors are parallel charged and series discharged by the coupled inductor. Thus, high step-up voltage gain can be achieved with an appropriate duty ratio. The voltage stress on the main switch is reduced by a passive clamp circuit. Therefore, the low resist...

A bidirectional converter (BDC) is required in areas where generated energy is stored. Some of the application areas are uninterruptible power system, transportation,, flywheel energy storage systems, etc. Bidirectional flow of power using buck mode and boost mode along with efficiency and high power density is important need of such systems. This report proposes a new topology of BDC with the ...

The main objective of this paper, a bidirectional dc–dc converter with duel coupled inductor is proposed. In the boost mode, two capacitors are parallel charged and series discharged by the coupled inductor. Thus, high step-up voltage gain can be achieved with an appropriate duty ratio. The voltage stress on the main switch is reduced by a passive clamp circuit. Therefore, the low resistance RD...

Enhancers are defined as DNA elements that increase transcription when placed in any orientation relative to a promoter. The major immediate-early (MIE) enhancer region of murine cytomegalovirus is flanked by transcription units ie1/3 and ie2, which are transcribed in opposite directions. We have addressed the fundamental mechanistic question of whether the enhancer synchronizes transcription o...
