Journal of Harbin Institute of Technology(New Series) 2024年第1期31卷 78-89页

The awareness amongst the researchers to develop an environment friendly sustainable material leads to explore new class of plant-based fiber for making composites. Hybridization of such plant-based fiber with inclusion of engineered fiber is one of the promising methods to not only enhanced the mechanical performance but also suppressed the drawbacks that associate with such plant-based fiber to some extent. A usual hand lay-up method was taken-up in this work to fabricate four layered of hybrid kenaf(k)/glass(G)polyester laminates with different stacking order such as kkkk,kGkG,kGGk,GkkG and GGGG. The erosive character of the laminates was examined under three distinct particle velocities(48m/s, 70m/s,82m/s)and four different impact angles(30°, 45°, 60°, 90°). All fabricated laminates exhibited a semiductile character at lower velocities(48m/s and70m/s)as peak wear rate was observed at45° impact angle. However,they showed a semi-brittle character at high velocity(82m/s)as maximum rate of erosion was noticed at60° impact angle. Again,the influence of stacking order of piles on erosion wear was also clearly noticed. moreover,the semi-brittle/semi-ductile characterization was also evidenced in accordance to the range of erosion efficiencies. The micro-structures of worn surfaces were inspected thoroughly from the images of scanning electron microscope(SEm)to evident the mechanism of erosion.

FmHADP: Design of an Efficient Pre-Forensic Layer for mitigating Hybrid Attacks via Deep Learning Pattern Analysis

Journal of Harbin Institute of Technology(New series) 2024年

作者： meesala Sravani B kiran kumar m Rekha Sundari D Tejaswi Department of Computer Science and Engineering， GmR Institute of Technology Information Technology， Anil Neerukonda Institute of Technology & Science(Autonomous)

Network attack detection and mitigation require packet collection， pre-processing， feature analysis， classification， and post-processing. models for these tasks sometimes become complex or inefficient when applied to real-time data samples. To mitigate hybrid assaults， this study designs an efficient forensic layer employing deep learning pattern analysis and multidomain feature extraction. In this paper， we provide a novel multidomain feature extraction method using Fourier， Z， Laplace， Discrete Cosine Transform (DCT)， 1D Haar Wavelet， Gabor， and Convolutional Operations. Evolutionary method dragon fly optimisation reduces feature dimensionality and improves feature selection accuracy. The selected features are fed into VGGNet and GoogLeNet models using binary cascaded neural networks to analyse network traffic patterns， detect anomalies， and warn network administrators. The suggested model tackles the inadequacies of existing approaches to hybrid threats， which are growing more common and challenge conventional security measures. Our model integrates multidomain feature extraction， deep learning pattern analysis， and the forensic layer to improve intrusion detection and prevention systems. In diverse attack scenarios， our technique has 3.5% higher accuracy， 4.3% higher precision， 8.5% higher recall， and 2.9% lower delay than previous models.
