Research ArticleOpen accessAll words, across the recordComparison and Analysis of Vertical Coherence in the Shallow Water of Two ocean regionV. G. Sivakumar, V. Rajendran, R. SaranyaNoise characteristics at shallow water is highly variable due to wave guide nature of the shallow water environment, reflection of noise from the bottom surface; due to biological activities and also due the sound speed in shallow water vary substantially. Thus noise field characterization is complex in shallow water. The ambient noise data was collected in the shallow water of … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 5 Jun 2013 · 6,488 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPreventing Injuries Via Innovative Investigations: Reviewing Dangerous Driving Research MethodsChris S. Dula, Russell Fox, Ashley Dickson et al.Dangerous driving behavior is particularly difficult to study for many reasons. Researchers must be creative to capture meaningful data, but innovative techniques often meet with problems that might be solved through the broader use by others. The researchers generally lack a central location from which to review and choose from past methods. This article reviews the techniques used to study … …Current Research in Psychology, Vol. 3, Issue 1 · 16 Jul 2012 · 7,283 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Alternative Graph Cut Algorithm for Morphological Edge DetectionP. RadhakrishnanProblem statement: Image analysis has some basic importance of edge detection. Characterize the object boundaries are helpful for object segmentation, registration and identification in a scene. There are many methods for edge detection, but it can be identified by two major methods, search-based and zero-crossing based. Approach: Proposed method tries to follow searching the edge points by applying graph cuts … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 29 May 2012 · 6,897 accessesView PDF Cite
