We propose a method for accurately tracking the spatial motion of standard laparoscopic instruments from video. By exploiting the geometric and photometric invariants common to standard FLS training boxes, the method provides robust and accurate tracking of instruments from video. The proposed method requires no modifications to the standard FLS training box, camera or instruments.

Collective male sexual violence is part of a continuum of sexual coercion in South Africa. This paper is based on long-term ethnographic work in an urban township in the former Transkei region. Drawing on intensive participant observation and interviews with young men in particular, it attempts to make sense of emergent narratives relating to streamlining, a local term for a not uncommon form o...

A Bayesian geostatistical model was used to identify factors related to topographical variation in the analysis of mortality risk for children less than 5 years of age in the 2008 Wenchuan earthquake in the People's Republic of China. Epidemiological data from a standardized survey were available from 115 locations across the study area. Physical and demographic factors measured directly at the...

Twp experiments were performed to investigate the effects of input stimuli's perceptual characteristics on visual hemifield asymmetries. The task used involved the temporal integration uf form: a stimulus was flashed in two incomplete but complementary flashes, which then had to be integrated over time into the complete stimulus. In this task, successful performance depends on the visible persi...

Despite the growing popularity of participatory peer education as an HIV-prevention strategy worldwide, our understandings of the processes underlying its impact on sexual norms are still in their infancy. Starting from the assumption that gender inequalities play a key role in driving the epidemic amongst young people, we outline a framework for conceptualizing the processes underlying success...

OBJECTIVES To describe the patterns and causes of childhood injury presenting to a South African township health centre in 1991. DESIGN Retrospective review of clinic held case notes. SETTING Typical South-African urban township within Greater Johannesburg. SUBJECTS 695 subjects aged 0-19 years presenting as a direct result of injury.

Reproduction and motherhood are among the most important components of women's identity throughout Mexico and, for many women, are the only vehicles for gaining recognition and status in the family and community. At the same time, however, abortion is a central experience in the lives of many women and carries with it the complexities and contradictions of women's reproductive and sexual health...

The past decades have witnessed a number of informal land developments on the urban fringe in China although many strict state regulations have been made to control this. The dual urban rural land system is widely believed to be one major determinant of informal developments in the existing literature. However, the important role of local villages and townships are often neglected. This paper a...

The paper focuses on improving the spectrum sharing using NSU, FLS and Traffic Pattern Prediction and also made comparison that traffic pattern prediction provides a better way of improving the spectrum utilization and avoids the spectrum scarcity. This helps to increase the number of active users, ease of identification of optimal users to use the spectrum with maximized coverage of the spectr...
