In this paper, we present a real-time algorithm for local simultaneous localization and mapping (SLAM) with detection and tracking of moving objects (DATMO) in dynamic outdoor environments from a moving vehicle equipped with a laser scanner and two radars. To correct vehicle location from odometry we introduce a new fast implementation of incremental scan matching method that can work reliably ...

Staggered grid Lagrangian schemes for compressible hydrodynamics involve a choice of how internal energy is advanced in time. The options depend on two ways of defining cell volumes: an indirect one, that guarantees total energy conservation, and a direct one that computes the volume from its definition as a function of the cell vertices. It is shown that the motion of the vertices can be defin...

abstract: in this paper a control scheme for grid-connected operation mode and the island state of distributed generation is presented. in normal conditions, every inverter dg system in micro-grids to supply a preset power, normally operate in a constant current control mode. when micro-grids removed from the network, dg inverter of each system must recognize the island and change position to v...

Occupancy-based monitoring has become an important tool in wildlife conservation and management. Nonetheless, meeting occupancy modeling assumptions providing biologically accurate information are difficult tasks over long time periods, large areas, or when multiple species. In frameworks, derived grids commonly used to divide landscapes into discrete units. Grid sizes that match the home range...

A quality improvement project was initiated on Ivory ward, a functional older adult psychiatric inpatient ward at Newham Centre for Mental Health, part of the East London NHS Foundation Trust. The project was started by staff on the ward after it had come to their attention that their ward had the highest bed occupancy and length of stay across similar wards in the trust. The mean bed occupancy...

The traditional model of acute medical care involves the admission of patients to hospital to be assessed by a consultant and facilitate access to investigation and treatment. This model has, however, led to a number of problems. Firstly, there is high bed occupancy which restricts access and increases the risk of healthcare-acquired infection. Secondly, only limited training opportunities are ...

This article presents a case study of how one health system-Health First, in Brevard County, Florida-addressed resource challenges by using Lean thinking enabled by information technology. Examining Health First provides an opportunity to learn about how one hospital system addressed these challenges by making fundamental changes in their operations, in advance of the shift toward accountable c...

We construct a stochastic patch occupancy metapopulation model that incorporates variation in habitat quality and an Allee-like effect. Using some basic results from stochastic ordering, we investigate the effect of habitat degradation on the persistence of the metapopulation. In particular, we show that for a metapopulation with Allee-effect habitat degradation can cause a dramatic decrease in...

Planning for mass gatherings involves health system preparedness based on an understanding of natural and technological hazards identified through prior risk assessment. We present the expected hazards reported by health administrators of the host cities for the 2014 FIFA World Cup in Brazil and discuss the hazards considering minimal available public hospital beds in the 12 cities at the time ...

Uncertainty about urban environments stems not only from imprecise pose estimation and noisy information in images but also the lack of semantic information. This article presents an approach to improve perception capability intelligent vehicles complex environments. The new method uses meta-knowledge extracted context associated with depth model occupancy grids stereo vision. It evidential for...
