Intelligent Intrusion Detection and Prevention System using Smart Multi-instance Multi-label Learning Protocol for Tactical Mobile Adhoc Networks

( M. Roopa ),( S. Selvakumar Raja ) 한국인터넷정보학회 2018 KSII Transactions on Internet and Information Syst Vol.12 No.6

Security has become one of the major concerns in mobile adhoc networks (MANETs). Data and voice communication amongst roaming battlefield entities (such as platoon of soldiers, inter-battlefield tanks and military aircrafts) served by MANETs throw several challenges. It requires complex securing strategy to address threats such as unauthorized network access, man in the middle attacks, denial of service etc., to provide highly reliable communication amongst the nodes. Intrusion Detection and Prevention System (IDPS) undoubtedly is a crucial ingredient to address these threats. IDPS in MANET is managed by Command Control Communication and Intelligence (C3I) system. It consists of networked computers in the tactical battle area that facilitates comprehensive situation awareness by the commanders for timely and optimum decision-making. Key issue in such IDPS mechanism is lack of Smart Learning Engine. We propose a novel behavioral based “Smart Multi-Instance Multi-Label Intrusion Detection and Prevention System (MIML-IDPS)” that follows a distributed and centralized architecture to support a Robust C3I System. This protocol is deployed in a virtually clustered non-uniform network topology with dynamic election of several virtual head nodes acting as a client Intrusion Detection agent connected to a centralized server IDPS located at Command and Control Center. Distributed virtual client nodes serve as the intelligent decision processing unit and centralized IDPS server act as a Smart MIML decision making unit. Simulation and experimental analysis shows the proposed protocol exhibits computational intelligence with counter attacks, efficient memory utilization, classification accuracy and decision convergence in securing C3I System in a Tactical Battlefield environment.

In vivo pharmacokinetic applicability of a simple and validated HPLC method for orally administered trans-resveratrol loaded polymeric nanoparticles to rats

Gurinder Singh,Roopa S. Pai,Vinay Pandit 한국약제학회 2014 Journal of Pharmaceutical Investigation Vol.44 No.2

A new formulation of trans-resveratrol nanoparticles(t-RVT NPs) with potential stealth properties wasprepared by nano-precipitation method in our laboratory. To investigate the pharmacokinetic of t-RVT NPs, a simpleand rapid high performance liquid chromatographicmethod was developed for the quantification of trans-resveratrolin plasma of rats treated with t-RVT NPs. Catechin(0.2 lg/ml) was used as an internal standard (IS). Thechromatographic separation was achieved on a reversedphaseC18 column using isocratic elution with methanol:10 mM potassium dihydrogen phosphate buffer (pH 6.8):3 % acetic acid solution (70:28:2, v/v/v) at a flow rate of1 ml/min with a total run time of 6 min. The columneffluent was monitored by UV detector at 306 nm. Calibrationcurve in plasma spiked with varying concentrationof trans-resveratrol were linear over the concentrationrange of 0.010–3.2 lg/ml with correlation coefficient of(r2[0.9987). The system was found to construct sharppeaks for trans-resveratrol and IS with retention times of3.82 and 5.49 min, respectively. The method was sensitivewith a limit of quantification of 0.007 lg/ml. The methodshowing accuracy, precision (inter-day relative standarddeviation (RSD) and intra-day RSD values\15.0 %. Themethod was applied for determining trans-resveratrolconcentration in plasma after oral administration of20 mg/kg of free trans-resveratrol and t-RVT NPs to rats. The plasma concentrations of trans-resveratrol and t-RVTNPs at 30 min and 10 h after oral administration werequantified as 0.1771 ± 0.38 and 5.64 ± 0.436 lg/ml. Results established selectivity and suitability of the methodfor pharmacokinetic studies of trans-resveratrol fromt-RVT NPs.

Partition energy of complete product of circulant graphs and some new class of graphs

E. Sampathkumar,S. V. Roopa,K. A. Vidya,M. A. Sriraj 장전수학회 2018 Advanced Studies in Contemporary Mathematics Vol.28 No.2

Let G = (V,E) be a graph and Pk = {V1, V2, ..., Vk} be a partition of V . The L-matrix with respect to a partition Pk of the vertex set V of graph G of order n is the unique square symmetric matrix Pk(G) = [aij ] with zero diagonal, whose entries aij with i 6≠ j are defined as follows: (i) If vi, vj ∈ Vr, then aij = 2 or −1 according as vivj is an edge or not. (ii) If vi ∈ Vr and vj ∈ Vs for r 6≠s, then aij = 1 or 0 according as vivj is an edge or not. For all Vi and Vj in Pk, i 6≠j remove the edges between vertices of Vi and Vj and add the edges between the vertices of Vi and Vj which are not in G, the resulting graph is called k-complement of G and is denoted by (G)k. For each set Vr in Pk, remove the edges of G joining the vertices within Vr and add the edges of G (complement of G) joining the vertices of Vr, the graph obtained is called k(i)-complement and is denoted by (G)k(i). The k-partition energy of a graph G with respect to partition Pk is denoted by EPk (G) and is defined as the sum of the absolute values of k-partition eigenvalues of Pk(G). In this paper we construct some graphs such that the graph and its 2-complement are equienergetic with respect to a given partition. We also determine partition energy of complete product of m copies of a circulant graph G and its subgraph, their k-complement and k(i)-complement.

Partition energy of a graph

E. Sampathkumar,S. V. Roopa,K. A. Vidya,M. A. Sriraj 장전수학회 2015 Proceedings of the Jangjeon mathematical society Vol.18 No.4

Let G = (V,E) be a graph. Let V1, V2, . . . , Vk be non-empty disjoint subsets of V such that union equal to V . Then {V1, V2, . . . , Vk} is called partition of vertex set V . Using this partition the graph G can be uniquely represented by a matrix called L-matrix Pk(G), whose entries belong to the set {2, 1, 0,−1} and defined as follows: aij = 8>>< >>: 2 if vi and vj are adjacent within the partition Vi, −1 if vi and vj are non-adjacent within the partition Vi, 1 if vi and vj are adjacent between the partition Vi and Vj for i 6= j, 0 otherwise. The eigenvalues of this matrix are called k-partition eigenvalues of G. The k-partition energy EPk (G) is defined as the sum of the absolute values of kpartition eigenvalues of G. We determine partition energy of some known graphs and also obtain bounds for EPk (G).

Vidya C. Shrikantaiah,Manjaunatha Basappa,Sangita Hazrika,Roopa Ravindranath 대한해부학회 2018 Anatomy & Cell Biology Vol.51 No.4

Portal vein provides about three-fourths of liver’s blood supply. Portal vein is formed behind the neck of pancreas, at the level of the second lumbar vertebra and formed from the convergence of superior mesenteric and splenic veins. The purpose of this study is to review the normal distribution and variation, morphometry of portal vein and its branches for their implication in liver surgery and preoperative portal vein embolization. It is also helpful for radiologists while performing radiological procedures. A total of fresh 40 livers with intact splenic and superior mesenteric vein were collected from the mortuary of Forensic Department, JSS Medical College and Mysuru Medical College. The silicone gel was injected into the portal vein and different segments were identified and portal vein variants were noted. The morphometry of portal vein was measured by using digital sliding calipers. The different types of portal vein segmental variants were observed. The present study showed predominant type I in 90% cases, type II 7.5% cases, and type III 2.5% cases. Mean and standard deviation (SD) of length of right portal vein among males and females were 2.096±0.602 cm and 1.706±0.297 cm, respectively. Mean and SD of length of left portal vein among males and females were 3.450±0.661 cm and 3.075±0.632 cm, respectively. The difference in the Mean among the males and females with respect to length of right portal vein and left portal vein was found to be statistically significant (P=0.010). Prior knowledge of variations regarding the formation, termination and tributaries of portal vein are very helpful and important for surgeons to perform liver surgeries like liver transplantation, segmentectomy and for Interventional Radiologists.

Nachiket Shankar,Nachiket Shankar,Yogitha Ravindranath,Roopa Ravindranath,Henal Shah 대한해부학회 2019 Anatomy & Cell Biology Vol.52 No.1

The aim of this study was to assess the effectiveness of a questionnaire to guide targeted remediation among undergraduate medical students in anatomy. Seventy-five students from a medical college in South India who failed in the first internal theory examination were administered a validated 35-item questionnaire. The total and domain specific questionnaire scores were calculated. Specific weekly interventions for each student based on the questionnaire scores were conducted by appointed academic mentors for three months prior to the second internal examination. The dependent variable was performance in the second internal examination. The students were re-administered the questionnaire after the second internal examination. The independent variables were the marks obtained in the first internal examination, domain specific and total questionnaire scores, sex, and regularity of the student in attending the remedial sessions. Inferential statistical tests used were the chi-square test, independent sample t test, paired t test, multiple regression and binomial logistic regression. Of the 75 students who underwent remediation, 54 (72%) passed in the second internal examination. The scores in the second internal examination among these students was found to be significantly higher as compared to the first internal examination. The total, subject related and study skills questionnaire score were significantly lower after remediation. Students who were irregular had a significantly lower pass rate. The multivariate analysis showed that only the first internal marks added significantly to the prediction about second internal performance. This study provides evidence to show that struggling students perceive a benefit from targeted remediation.

Prediction and characterization of novel microRNAs from brown plant hopper, Nilaparvata lugens (Stål) (Hemiptera: Delphacidae)

MicroRNAs (miRNAs) are a family of small, endogenously initiated non‐coding RNAs that extensively regulate gene expression either by mRNA cleavage or by translational repression, thus playing important roles in the development and physiology of organisms. Experimental identification and characterization of spatially and temporally expressed miRNAs is a monumental task in insects such as the brown plant hopper, Nilaparvata lugens, a major pest of rice and also a vector of Tenuivirus. At this juncture bioinformatics approaches, which primarily depend on sequence homology and secondary structure verification, will be an invaluable tool. A total of nine novel miRNAs were identified in N. lugens using the computational approaches from 1 13 718 Expressed Sequence Tags. The phylogenetic analysis was carried out to compare their level of conservation with respect to other members of the animal kingdom. The functional annotation of these newly identified miRNAs revealed that the majority of them are involved in the transcription regulatory activity and signal transduction pathways. These regulatory impacts are promising towards insect pest management but need further experimental validation and functional analyses. Thus, the outcome of this study will help to carry out the gene knockdown and transgenesis studies for the functional analysis of the newly identified miRNA‐regulated phenotypes in N. lugens.
