Recently, social networking over MANETs has attracted the attention of research community, due to its flexibility, cost saving and infrastructure-less architecture. However, various problems namely, to efficiently find nodes of similar interest and network partition, exist in such environment. For enabling ad hoc social networking in an intermittent network scenario, Delay Tolerant Network (DTN...

It is hypothesized that social networks facilitate transmission of the hepatitis C virus (HCV). We tested for association between HCV phylogeny and reported injecting relationships using longitudinal data from a social network design study. People who inject drugs were recruited from street drug markets in Melbourne, Australia. Interviews and blood tests took place three monthly (during 2005-20...

background and objectives: the escherichia coli strains are greatly important in nosocomial and community acquired infections. the aim of this study was to determine the transmission of bacterial infections using genetic analysis. materials and methods: two hundred and thirty escherichia coli strains, isolated from different clinical samples, were characterized by enterobacterial repetitive int...

In this paper, we apply an efficient top-k shortest distance routing algorithm to the link prediction problem and test its efficacy. We compare the results with other base line and state-of-the-art methods as well as with the shortest path. Our results show that using top-k distances as a similarity measure outperforms classical similarity measures such as Jaccard and Adamic/Adar.

A graph in van Eck and Waltman [JASIST 60(8), 2009, p. 1644], representing the relation between the Association Strength and the Cosine, is partially explained as a sheaf of parabolas, each parabola being the functional relation between these similarity measures on the trajectories . X Y a  , a constant. Based on earlier obtained relations between Cosine and other similarity measures (such as ...

This study provides taxonomic and ecological data on Hemiptera (Insecta) order prevalence in Berati region habitats Southern Albania. Diverse natural environments, fields, hilly mountainous characterize this region. The expeditions for the biological material collection were organized during 2018-2020 six stations from May to September. Our refers 38 species, representing 28 genera 10 families ...

Metamorphic malware modifies its code structure using a morphing engine to evade traditional signature-based detection. Previous research has shown the use of opcode instructions as feature representation with Hidden Markov Model in context metamorphic However, it would be more feasible extract file at fine-grained level. In this paper, we propose novel detection approach by generating structur...

Clustering of web documents enables (semi-)automated categorization, and facilitates certain types of search. Any clustering method has to embed the documents in a suitable similarity space. While several clustering methods and the associated similarity measures have been proposed in the past, there is no systematic comparative study of the impact of similarity metrics on cluster quality, possi...

This paper is devoted to propose cosine, Dice and Jaccard similarity measures of interval rough neutrosophic set and interval neutrosophic mean operator. Some of the properties of the proposed similarity measures have been established. We have proposed multi attribute decision making approaches based on proposed simlarity measures. To demonstrate the applicability and efficiency of the proposed...
