Degree of an edge and Platt Number in signed networks

Positive labelled edges play a vital role in network analysis.The degree of edges in signed graphs is introduced by giving importance topositive edges incident on the end vertices of that edge. The conceptof Platt number of a graph, which is the sum of degrees of its edges, isextended to signed graphs based on the degree defined. Bounds of degree of an edge and Platt number in certain classes of signed graphsare determined. Some characterizations on Platt number of signedgraphs are also established. A model to analyse social networks using degree of edges and Platt number is also proposed.Keywords: Signed graph, positive edges, negative edges, networks,information diffusion, degree of an edge, Platt numbe

Cyber Crime Detection and Prevention Techniques on Cyber Cased Objects Using SVM and Smote

Conventional cybersecurity employs crime prevention mechanisms over distributed networks. This demands crime event management at the network level where Detection and Prevention of cybercrimes is a must. A new Framework IDSEM has been introduced in this paper to handle the contemporary heterogeneous objects in cloud environment. This may aid for deployment of analytical tools over the network. A supervised machine learning algorithm like SVM has been implemented to support IDSEM. A machine learning technique Like SMOTE has been implemented to handle imbalanced classification of the sample data. This approach addresses imbalanced datasets by oversampling the minority classes. This will help to solve Social Engineering Attacks (SEA) like Phishing and Vishing. Classification mechanisms like decision trees and probability functions are used in this context. The IDSEM framework could minimize traffic across the cloud network and detect cybercrimes maximally. When results were compared with existing approaches, the results were found to be good, leading to the development of a unique SMOTE algorithm

Synthesis of 2-N-heptyl-5,9-dimethyl-6,7-benzomorphan from 3,4-lutidine was effected in three step process and only a-form could be obtained through phosphoric acid cyclisation. This a-form of benzomorphan was converted in three steps to a-2N-hepthyl-2-hydroxy-5,9-dimethyl-6,7-benzomorphan, which was also synthesised from alternative route. Infrared spectrum of the base confirmed the presence of a-from
