Travel for medical care is increasing globally.

متن کاملMedical Aspects of Travel: Editorial Overview
Interest in tropical medicine began several hundred years ago, when Europeans, primarily, traveled to Africa, Asia, and Latin America in search of land, adventure, and riches.

Eventually, interest expanded from treat...
متن کاملtravel time ∗
In this paper we use a model-based traffic control approach to determine dynamic speed limits with the aim of reducing fuel consumption and emissions, while still guaranteeing small travel times. The approach we propose is based on model predictive control (MPC). MPC is a modelbased control design method that combines prediction and on-line optimization of a performance criterion over a given t...
متن کاملTime Travel and Time Machines
This paper is an enquiry into the logical, metaphysical, and physical possibility of time travel understood in the sense of the existence of closed worldlines that can be traced out by physical objects. We argue that none of the purported paradoxes rule out time travel either on grounds of logic or metaphysics. More relevantly, modern spacetime theories such as general relativity seem to permit...
متن کاملTravel cost and time measurement in travel cost models TRAVEL COST AND TIME MEASUREMENT IN TRAVEL COST MODELS
In this paper we use the results of a recent on-site recreation survey to know whether it matters to use perceived rather than calculated travel costs. The calculated travel costs (time and money) are derived from detailed GIS computations. The perceived travel times and costs are taken directly from the survey responses. We first find that there is a high non-response rate for the perceived co...
