Many reliability prediction techniques require an estimate for the number of residual faults. In this paper, a new theory is developed for using test coverage to estimate the number of residual faults. This theory is applied to a specific example with known faults and the results agree well with the theory. The theory is used to justify the use of linear extrapolation to estimate residual fault...

BACKGROUND To compare the cost-effectiveness of nutrition programs, the anticipated nutritional benefits of each intervention must be expressed using a common metric. OBJECTIVE We present the methodology for estimating the benefits of vitamin A (VA)-related interventions among women and children in Cameroon. METHODS We estimated "reach" (proportion of the population that receives a program)...

This analysis was conducted to determine how personal and community characteristics affect coverage by private insurance to supplement Medicare. Data from the 1980 National Medical Care Utilization and Expenditure Survey were used. After controlling for health status, it was found that supplemental coverage was positively associated with education, income, number of self-reported chronic condit...

Barrier coverage in a sensor network has the goal of ensuring that all paths through the surveillance domain joining points in some start region S to some target region T will intersect the coverage region associated with at least one sensor. In this paper, we revisit a notion of redundant barrier coverage known as k-barrier coverage. We describe two different notions of width, or impermeabilit...

OBJECTIVE To determine the coverage provided by the Kimberley Diabetic Retinopathy Screening Program and evaluate the impact of the Kimberley diabetic eye health coordinator (KDEHC) position using an evidence-based approach. DESIGN Retrospective audit. SETTING Primary care services in the Kimberley region of Western Australia. PARTICIPANTS Individuals with diabetes mellitus who underwent ...

This paper explores Colombia's road toward universal health care coverage. Using a policy-based approach, we show how, in Colombia, the legal expansion of health coverage is not sufficient and requires the development of appropriate and effective institutions. We distinguish between formal and material health coverage in order to underscore that, despite the rapid legal expansion of health care...

We consider the problem of coverage path planning in an initially unknown or partially known planar environment using multiple robots. Previously, Voronoi partitioning has been proposed as a suitable technique for coverage path planning where the free space in the environment is partitioned into non-overlapping regions called Voronoi cells based on the initial positions of the robots, and one r...

The number of vaccines available to low-income countries has increased dramatically over the last decade. Overall infant immunization coverage in the WHO African region has stagnated in the past few years while countries' ability to maintain high immunization coverage rates following introduction of new vaccines has been uneven. This case study examines post-introduction coverage among African ...

This study developed and validated a model for predicting the probability that communities in Amhara Region, Ethiopia, have low sanitation coverage, based on environmental and sociodemographic conditions. Community sanitation coverage was measured between 2011 and 2014 through trachoma control program evaluation surveys. Information on environmental and sociodemographic conditions was obtained ...

Sensing coverage maintenance is concerned with providing coverage to a targeted region with prolonged system lifetime by utilizing redundant deployment of sensor nodes. Most existing approaches to coverage maintenance require knowledge of accurate location information. In this paper, we propose a novel location-free coverage maintenance scheme in wireless sensor networks that exploits power con...
