Obtaining virtual models from real buildings, terrains or building works is a matter of increased interest in construction. The application of such models ranges from technical use in architecture and civil engineering, to multimedia presentation or remote visits through the web. This is becoming possible thanks to recent advances in laser scanning technology and related 3D processing algorithm...

Background The new global target for maternal mortality ratio (MMR) is a ratio below 70 maternal deaths per 100 000 live births by 2030. We undertook a systematic review of methods used to measure MMR in low- and middle-income countries. Sources of data Systematic review of the literature; 59 studies included. Areas of agreement Civil registration (5 studies), census (5) and surveys (16), R...

Vital statistics generated through civil registration systems are the major source of continuous monitoring of births and deaths over time. The usefulness of vital statistics depends on their quality. In the second paper in this Series we propose a comprehensive and practical framework for assessment of the quality of vital statistics. With use of routine reports to the UN and cause-of-death da...

This paper proposes range imaging as a means to improve object registration in an augmented reality environment. The addressed problem deals with virtual world construction from complex scenes using object models. During reconstruction, the scene view is augmented by superimposing virtual object representations from a model database. The main difficulty consists in the precise registration of a...

To measure and evaluate collaborative learning there is a need for tools that promote and record the interactions that occur within and between learners. Considering the requirements of Kelluwen learning community and didactical designs that are developed, shared and enforced, plus a review of collaborative learning platforms, it became necessary to implement a Virtual Worklog module for kelluw...

The civil construction industry has an operation way similar to virtual organizations, but in not structuralized form, leaving to provide competitive advantages. For in such a way, the paper will propose, through analytical research and case studies and based on EKD (Enterprise Knowledge Development) methodology, the Process Model to support the coordination of collaborative networks in the civ...
