Abstact A new design approach is proposed for a fault coverage circuit. In this design a linear feedback shift register which is called as LT_LFSR (Low Transition Linear Feedback Shift Register) is used. Using LT_LFSR reduces the power consumption by reducing the number of transitions during test mode. Power reduction is done by implementing two new test pattern generation methods in LFSR. In b...

A standard model of nonlinear combiner generator for stream cipher system combines the outputs of several independent Linear Feedback Shift Register (LFSR) sequences using a nonlinear Boolean function to produce the key stream. Given such a model, cryptanalytic attacks have been proposed by finding out the sparse multiples of the connection polynomials corresponding to the LFSRs. In this direct...

Introduction: To investigate the effects of predictable and unpredictable external perturbations on cortical activity in healthy young and older adults. Methods: Twenty healthy older and 19 healthy young adults were exposed to predictable and unpredictable external perturbations, and their cortical activity upon postural recovery was measured using a 32-channel quantitative encephalography. Th...

The filter generator consists of a linear feedback shift register (LFSR) and a Boolean filtering function that combines bits from the shift register to create a key stream. The nonlinear combiner generator employs several (LFSRs) and a Boolean function that combines bit from all the registers to generate the key stream. A new attack on the filter generator has recently been described by Rønjom ...

Using players’ Shapley–Shubik power indices, Peleg [4] proved that voting by count and account is more egalitarian than voting by account. In this paper, we show that a stronger shift in power takes place when the voting power of players is measured by their Shapley– Shubik indices. Moreover, we prove that analogous power shifts also occur with respect to the absolute Banzhaf and the absolute J...

Wireless power transfer is the technology that enables a power source to transmit electromagnetic energy to an electrical load across an air gap without interconnecting cords.However, its widespread application is hampered due to the relatively low efficiency of current Wireless power transfer (WPT) systems this study presents a concept to maximize the efficiency as well as to increase the amou...

A switched-capacitor-based battery equalizer using level-shift circuits is proposed in this paper. In conventional equalizers using diode switches, the threshold voltage of diode switches causes a decrease in power efficiency. Unlike conventional equalizers, the proposed equalizer alleviates the threshold-voltage-drop of switches by using level-shift circuits. Therefore, the proposed equalizer ...

MC-CDMA has attracted significant attention as one of the down link communication method for fourth generation mobile communication systems. However, MC-CDMA has a peak power problem as well as the other non-spread multi-carrier systems. In this paper, we propose novel peak power reduction technique for MC-CDMA using code selection at the transmitter. In the proposed system, the transmitter sel...
