The problem of enhancing speech degraded by uncorrelated additive noise, when the noise speech alone available, has recently received much attention. Beamforming is one possible method of speech enhancement, because, the beamformer minimizes the output signal power but maintains signals from the desired direction. Beamforming techniques basically approach(More)
HIV and AIDS incidence in China is high among men who have sex with men (MSM) and ours was one of few studies in China to evaluate the role of HIV risk reduction counseling and testing. Respondent-driven sampling (RDS) was used to recruit 430 MSM. Participants were followed up at 6, 12 and 18 months to evaluate behavioral changes after counseling to reduce(More)
Problem Statement: In many cases it would be helpful to include already existing data with the GIS for interpretation of remote sensing data. Object Based Image Analysis (OBIA) is a technology for image analysis which addresses exactly those problems hampering a successful bridging of Remote Sensing and GIS. In order to provide potential strategies to meet(More)
INTRODUCTION The carbohydrate 'fuel' metabolism in a pregnant woman may have a long-term impact on the development of her offspring ('fuel-mediated teratogenesis' hypothesis) including in utero exposure to maternal hyperglycaemia leading to fetal hyperinsulinaemia, and the consequent increase in fetal fat cells. Therefore, a feed-forward loop can exist of(More)
BACKGROUND Screening and timely treatment of gestational hyperglycaemia (GH) is proved to be beneficial and improves maternal and foetal health outcomes. To understand screening practices, we explored the knowledge and perceptions of doctors working in public health facilities in Bangalore, India. We also studied participation factors by examining whether(More)
Remote sensing systems designed to monitor the surface environment employ a multispectral design such as parallel sensor arrays thereby detecting radiation in a small number of broad wavelength bands in order to provide increased spectral discrimination. These broad-band multispectral systems allow discrimination of different types of vegetation, rocks and(More)
BACKGROUND Migrant men who have sex with men (MSM) have a higher predisposition for HIV transmission. We aimed to determine and compare the prevalence and trends of HIV, Syphilis, and HCV between migrant and resident MSM in Shandong, China. METHODS A serial cross-sectional study was conducted in eight cities in Shandong, China from 2010 to 2014. The(More)
BACKGROUND India is experiencing an epidemic of obesity-hyperglycaemia, which coincides with child bearing age for women. The epidemic can be sustained and augmented through transgenerational transmission of adiposity and glucose intolerance in women. This presents an opportunity for exploring a clear strategy for the control of this epidemic in India. We(More)
CONTEXT Quantitative and Qualitative studies have been widely used in isolation to estimate several associations in developing countries, but little is known about combining both methods in a given study and ascertains validity. AIMS The objective of the following study was to accurately measure the constructs and to check for the internal consistency(More)
