Recent internet development is helping malware researchers to generate malicious code variants through automated tools. Due to this reason, the number of malicious variants is increasing day by day. Consequently, the performance improvement in malware analysis is the critical requirement to stop the rapid expansion of malware. The existing research proved that the similarities among malware variants could be used for detection and family classification. In this paper, a Cross-Platform Malware Variant Classification System (CP-MVCS) proposed that converted malware binary into a grayscale image. Further, malicious features extracted from the grayscale image through Combined SIFT-GIST Malware (CSGM) description. Later, these features used to identify the relevant family of malware variant. CP-MVCS reduced computational time and improved classification accuracy by using CSGM feature description along machine learning classification. The experiment performed on four publically available datasets of Windows OS and Android OS. The experimental results showed that the computation time and malware classification accuracy of CP-MVCS was higher than traditional methods. The evaluation also showed that CP-MVCS was not only differentiated families of malware variants but also identified both malware and benign samples in mix fashion efficiently.

Prediction of the Current-Voltage Characteristics and the Bipolar Resistive Switching Mechanism in Polymer-Based Sandwiched Structures

Muhammad Naeem Awais,Muhammad Naeem Shehzad 한국물리학회 2019 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.75 No.5

The prediction of the current-voltage (IV) characteristics of resistive switching devices has remained a challenge before their physical realization. This research work addresses the prediction of the IV characteristics and the bipolar switching mechanism of polymer-based resistive switches by examining their structures before their fabrication. The research was carried out through an analytical study of the device structure, thereby correlating the predicted IV curve to the \textit{in-situ} IV characteristics of the device. Different types of the device structures were considered, depending upon the work function of the top and the bottom electrodes and the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) levels of the sandwiched layer. We concluded that the defects/traps within the sandwiched layer lead to the interface effect being the dominant switching mechanism driving the polymer-based resistive switches. Furthermore, we also found that the devices following the interface effect are driven from trap-limited space-charge-limited current (SCLC) conduction to trap-free SCLC conduction as their current conduction mechanisms.

Whole-exome sequencing identifies a novel LRAT mutation underlying retinitis punctata albescens in a consanguineous Pakistani family

Retinitis punctata albescens (RPA) is an ocular disease characterized by decreased visual acuity, night blindness, atropic maculopathy, and pigmentary retinopathy. Multiple genes have been linked to the etiology of RPA. In this study, we investigated the genetic causes of RPA in a consanguineous Pakistani family with multiple affected individuals. We performed whole-exome sequencing of seven family members, and screened variants co-segregating with RPA in recessive fashion. Bioinformatic and in silico analyses revealed that all affected individuals were homozygous for a novel mutation that substitutes glycine with arginine at position 66 (c.196 G[C) in exon 2 of the lecithin retinol acyltransferase (LRAT) that converts all-trans retinol to 11-cis retinal in the retinal pigment epithelium. This mutation was not present in 217 unrelated Pakistani control subjects nor in the Exome Aggregation Consortium database containing exome data from 60,638 individuals worldwide. Mutations in the LRAT gene were previously found from the patients with Leber congenital amaurosis and retinal dystrophy, however, we report first time that disruptions in this gene are also associated with RPA.

In this work, activated carbon (AC) web was prepared using physical activation under the layer of charcoal in high temperature furnace. The carbonization of acrylic fibrous waste was performed at different temperatures (800 ℃, 1000 ℃, and 1200 ℃) with heating rate of 300 oC/h and at different holding time. At 1200 ℃, the heating rate of 300 ℃/h and no holding time provided better results of surface area as compared to carbonization at 800 ℃ and 1000 ℃. The activated carbonweb (AC) prepared at 1200 oC was used for removal of Acid Red 27 dye from aqueous media by varying different parameters like initial concentration of dye, stirring speed, adsorbent dosage, and pH. The results were evaluated using non-linear forms of Langmuir and Freundlich isotherms. The Freundlich isotherm was found to describe the results more effectively because of non-homogenous surface of activated carbon web. Further, the kinetics of adsorption was examined using linear and nonlinearforms of pseudo 1st order and pseudo 2nd order.

Flexural stress and crack sensing capabilities of MWNT/cement composites

Naeem, Faizan,Lee, H.K.,Kim, H.K.,Nam, I.W. ELSEVIER (APPLIED SCIENCE) 2017 COMPOSITE STRUCTURES -BARKING THEN OXFORD- Vol.175 No.-

<P><B>Abstract</B></P> <P>The flexural stress/crack sensing capabilities of multi-wall carbon nanotube (MWNT)/cement composite sensors were investigated in this study. The electrical/mechanical characteristics of the composites were explored with respect to the MWNT contents, prior to evaluating the sensing capabilities of the composites. A dramatic increase (over three orders) in the electrical conductivity, compressive and flexural strength (36% and 18%) were observed in the composite specimens. The sensing capabilities of the composites were evaluated by monitoring the electrical resistance change of the composites under loading. The composites subjected to flexural stress showed higher sensing capability as the MWNT content was increased. Both stress and crack sensing capability were enhanced with the increase of MWNT content. In addition, the examination demonstrated that an embedment of MWNT content of 0.6wt% resulted in the best sensing capabilities. Lastly, the composites were embedded in two different locations of reinforced mortar beams for in-situ monitoring of electrical resistance. A dramatic change in the resistance of the composites were accompanied at failure of the mortar, regardless of the sensor location. The obtained result may have implications for the use of the composites as a stress/crack sensor in cement-based composite structures.</P>

Analysis of weld-induced residual stresses and distortions in thin-walled cylinders

Naeem Ullah Dar,Ejaz M. Qureshi,M.M.I Hammouda 대한기계학회 2009 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.23 No.4

Circumferential weld specifically in thin-walled structures is a common joint type in the fabrication of structural members in aerospace, aeronautical and pressure vessel industries. This type of weld joint suffers various types of weld-induced residual stress fields (hoop and axial) and deformation patterns (axial shrinkage, radial shrinkage). These imperfections have negative effects on fabrication accuracies and result in low strength welded structures that can lead to premature failures. To precisely capture the distortions and residual stresses, computational methodology based on three-dimensional finite element model for the simulation of gas tungsten arc welding in thin-walled cylinders is presented. Butt-weld geometry with single "V" for a 300 mm outer diameter cylinder of 3 mm thick is used. The complex phenomenon of arc welding is numerically solved by sequentially coupled transient, non-linear thermo-mechanical analysis. The accuracy of both the thermal and structural models is validated through experiments for temperature distribution, residual stresses and distortion. The simulated result shows close correlation with the experimental measurements.

<P><B>Abstract</B></P> <P>This research proposes a self-centering passive damping system consisting of a spring viscous damper linked with a preloaded tendon. The seismic performance of the spring viscous damper is evaluated by cyclic loading tests, and the results are used for the formulation of an analytical model of the retrofit system in the structural analysis program. The shaking table tests of a two-story steel frame installed with the proposed damping system are carried out using five different earthquake records. The results from the shaking table tests are verified by numerical simulation of the retrofitted structure.
