Changing patterns of family formation among internally displaced populations in Yemen: evidence from cross-sectional surveys.

Introduction: Yemen has one of the highest rates of child marriage in the Middle East and North Africa region and is home to one of the world's worst humanitarian crises. How the conflict and resulting displacement have impacted family formation patterns is not entirely clear. In this study, we investigate the impact of displacement on child marriage and early childbearing by comparing time-to-first-marriage and time-to-first-birth among displaced and non-displaced girls.

Novel Bayesian Inference-Based Approach for the Uncertainty Characterization of Zhang's Camera Calibration Method.

Camera calibration is necessary for many machine vision applications. The calibration methods are based on linear or non-linear optimization techniques that aim to find the best estimate of the camera parameters. One of the most commonly used methods in computer vision for the calibration of intrinsic camera parameters and lens distortion (interior orientation) is Zhang's method.

3D Trajectory Planning Method for UAVs Swarm in Building Emergencies.

The development in Multi-Robot Systems (MRS) has become one of the most exploited fields of research in robotics in recent years. This is due to the robustness and versatility they present to effectively undertake a set of tasks autonomously. One of the essential elements for several vehicles, in this case, Unmanned Aerial Vehicles (UAVs), to perform tasks autonomously and cooperatively is trajectory planning, which is necessary to guarantee the safe and collision-free movement of the different vehicles.

A Novel Online Approach for Drift Covariance Estimation of Odometries Used in Intelligent Vehicle Localization.

Localization is the fundamental problem of intelligent vehicles. For a vehicle to autonomously operate, it first needs to locate itself in the environment. A lot of different odometries (visual, inertial, wheel encoders) have been introduced through the past few years for autonomous vehicle localization.
