Our daily life leaves an increasing amount of digital traces,footprints that are improving our lives.Data-mining tools,like recommender systems,convert these traces to information for aiding decisions in an ever-increasing number of areas in our lives.The feedback loop from what we do,to the information this produces,to decisions what to do next,will likely be an increasingly important factor in human behavior on all levels from individuals to societies.In this essay,we review some effects of this feedback and discuss how to understand and exploit them beyond mapping them on more well-understood phenomena.We take examples from models of spreading phenomena in social media to argue that analogies can be deceptive,instead we need to fresh approaches to the new types of data,something we exemplify with promising applications in medicine.

NUMERICAL ANALYSIS OF BURNING PROCESS OF FUEL BED

引用

Progress in Natural Science:Materials International 1991年第6期 559-565页

作者：汪箭范维澄 Department of Engineering Thermophysics University of Science and Technology of China Hefei 230026 PRC

Ⅰ.INTRODUCTIONBurning of a fuel bed is the radical combustion phenomenon in fires which has beenstudied experimentally and numerically as well.It is needed to develop the general modelsand numerical methods for prediction of the burning process of a fuel bed with differentcharacters.As a first step three kinds of fuel beds have been chosen for demonstration ofthe predictions by use of FAC-2 computer code.They are a vertically-placed flat,a liquidpool and a porous bed.These fuel beds can be considered as a model of a wall fire,apetroleum fire and a forest fire respectively.
