In this study, a carbon nanotube (CNT) buckypaper was interleaved in carbon-fiber-reinforced polymer (CFRP) composite to improve the interlaminar fracture toughness. Interleaving film of laminate-type poses risk deteriorating in-plane mechanical properties. Therefore, shear modulus and strength were measured prior estimating To evaluate effect on toughness CFRP, double cantilever beam (DCB) end...

In this paper, we propose a chaotic interleaving scheme for continuous-phase modulation based orthogonal frequency-division multiplexing (CPM-OFDM) systems. The idea of chaotic maps randomization (CMR) is exploited in this scheme. CMR generates permuted sequences from the sequences to be transmitted with lower correlation among their samples, and hence a better bit error rate (BER) performance ...

DS-CDMA with minimum mean square error frequency-domain equalization (MMSE-FDE) can provide much better performance than that with rake combining in a frequency-selective fading channel and is comparable to that of MC-CDMA with MMSEFDE. Chip interleaving is a form of channel interleaving that improves the DS-CDMA performance by converting the channel into a highly time-selective channel; the ti...

In this paper we investigate the action of ambient turbulence on thermohaline interleaving using both theory and numerical calculations in combination with observations from Meddy Sharon and the Faroe Front. We improve upon the highly simplified models of ambient turbulence used previously by allowing turbulent diffusivities of momentum, heat and salt to depend on background gradients and to ev...

In this paper, we investigate the costs and benefits of implementing memory interleaving in software. As our main contribution, we compare software memory interleaving to row-major allocation and logarithmic broadcasting. Our analysis demonstrates the clear superiority of software interleaving over row-major allocation in the presence of memory contention. Our analysis also indicates that the c...

Conventional time domain rake combining can be replaced by minimum mean square error frequency domain equalisation (MMSE–FDE) with much better performance in a frequencyselective fading channel, since the frequency selectivity of the channel is thoroughly exploited. Chip interleaving is a form of channel interleaving that improves the DS–CDMA performance by taking advantage of the time selectiv...
