Exposure to high altitude (HA), especially extreme altitude, is associated with impairment of cognitive functions including memory and increased oxidative stress. However, the underlying mechanisms involved are not well understood. It is hypothesized that HA induced oxidative stress may be one of the factors underlying hypoxia induced memory impairment. The(More)
BACKGROUND While many studies have compared the efficacy of Pap cytology, visual inspection with acetic acid (VIA) and human papillomavirus (HPV) DNA assays for the detection cervical intraepithelial neoplasia and cancer, few have evaluated the program effectiveness. METHODS AND FINDINGS A population-based sample of 5603 women from Medchal Mandal in(More)
Wireless sensor networks and communication technologies have dramatically revolutionized our lives and have hitherto spurred a host of applications in fields like surveillance and target tracking. Collaborative sensor networks largely depend on statistical estimation theory to estimate the target trajectory. Recent research has reported the use of a variety(More)
BACKGROUND Altered renal function is an essential component of the pathophysiological process in pre-eclampsia. Kidneys play an important role in the turnover of low molecular weight substances such as creatinine, uric acid and cystatin C. The present study was undertaken if these serum markers were characteristically altered in Indian pregnant women. (More)
In the web usage mining process, the techniques of data mining are applied so as to discover the trends and the patterns in the browsing nature of the visitors of the website. There is extraction of the navigation patterns as the browsing patterns could be traced and the structure of the website can be designed accordingly. This information can be extracted(More)
Support Vector Machine (SVM) is a powerful classification technique based on the idea of Structural Risk Minimization. The main idea behind the Support Vector Machine is to separate the classes with a surface that maximizes the margin between them. Key Property of SVM is Kernels. However, a proper Kernel Function for a certain problem is dependent on the(More)
Classification has its roots deep inside the area of prediction and analytics. Performing effective classification can provide huge advantages and improvements in several area. The huge downsides are the unavailability of enhanced techniques and the huge time consumption associated with several machine learning techniques. This paper presents a(More)
Classification is a learning function that maps a given data item into one of several predefined classes. It is a data analysis technique that extracts models describing important data classes and predicts future values. Basically, classification techniques have better capability to handle a wider variety of datasets than regression. It can also be(More)
