To maximize network lifetime in Wireless Sensor Networks (WSNs) the paths for data transfer are selected in such a way that the total energy consumed along the path is minimized. To support high scalability and better data aggregation, sensor nodes are often grouped into disjoint, non overlapping subsets called clusters. Clusters create hierarchical WSNs(More)
PURPOSE To report a case of ruptured abdominal aortic aneurysm (AAA) treated with a commercially available endoluminal graft. CASE REPORT Ruptured AAA was diagnosed in a 58-year-old man with lower abdominal pain, hypotension, and syncope. A contrast-enhanced computed tomographic (CT) scan confirmed the presence of a 7-cm ruptured infrarenal AAA associated(More)
Prostate tissue characteristics play an important role in predicting the recurrence of prostate cancer. Currently, experienced pathologists manually grade these prostate tissues using the Gleason scoring system, a subjective approach which summarizes the overall progression and aggressiveness of the cancer. Using advanced image processing techniques, Aureon(More)
BACKGROUND Transnasal endoscopic repair has become the treatment of choice for most anterior cranial and all sphenoid sinus breaches. The aim of this paper is to evaluate the results of endoscopic management of cerebrospinal fluid (CSF) rhinorrhea in a tertiary care center in South India. MATERIALS AND METHODS A retrospective analysis of 40 consecutive(More)
Electroencephalogram (EEG) is a time varying brain electrical activity, highly sensitive and gives a coarse view of neural activity. It has been used to study cognitive processes and the physiology of the brain. EEG recordings are distorted by physiological and non-physiological signals causing problems to the clinicians, neuropsychologist and researchers(More)
In this paper we propose a novel detail-enhancing exposure fusion approach using nonlinear translation-variant filter (NTF). With the captured Standard Dynamic Range (SDR) images under different exposure settings, first the fine details are extracted based on guided filter. Next, the base layers (i.e., images obtained from NTF) across all input images are(More)
