With the increasing demand on knowledge sharing and problem solving, there is a growing participation on online Question & Answer (Q&A) forums in the recent past. We classify the online community participation on Stack Exchange into two different genres, one is technical and another is non-technical. Though several studies have measured community(More)
Network intrusion detection has remained a field of rigorous research over the past few years. Advances in computing performance, in terms of processing power and storage, have allowed the use of resource-intensive intelligent algorithms, to detect intrusive activities, in a timely manner. Genetic Algorithms have emerged as a powerful domain-independent(More)
Using Social Network Sites (SNS) as an information source has drawn the attention of the researchers for a while now. There has been many works that analyzed the types and topics of questions people ask in these networks and why. Topics like what motivate people to answer such queries, how to integrate the traditional search engines and SNS together are(More)

Background Spirometry is an objective and reproducible test of lung function. It measures how quickly full lungs can be emptied and the total volume of air expired. The most important measurements obtained from the spirometry test are FEV1. The FEV1 is the volume expired in the first second of maximal expiration initiated at full inspiration, and is one(More)
Objective: To observe the outcome of Close Lateral Internal Anal Sphincterotomy with minimally invasive Von Greaves (cataract) knife in terms of symptomatic relief, continence and complications. Methodology: Patients with chronic anal fissure were included in the study after taking informed consent. Patients with concomitant other ano-rectal pathologies(More)
In order to achieve a satisfactory optimization performance by evolutionary programming (EP), it is necessary to ensure proper balance between exploration and exploitation. It is obvious that one single mutation operator is not the answer. Moreover, early loss of genetic diversity causes premature trapping around locally optimal points of the fitness(More)
