System Dynamics Simulation of Energy Saving and Emission Reduction in Coal Mining Area
This paper established a system dynamics model of energy saving and emission reduction in coal mining area, as well as conducted simulation of different development plans, based on the analysis of energy saving and emission reduction factor of coal production links, of the complex structure of energy saving and emission reduction system in coal mining area, and of the dynamic feed-back mechanis...
متن کاملSimulation of the Energy Saving and Emission Reduction in Coal Mine Areas Based on System Dynamics
Abstract: In order to find the main direction of energy saving and emission reduction in coal mine areas, this paper established a system dynamic model for energy consumption and environmental pollution produced in coal mining process, and took a typical coal mine as the case to simulate the energy saving and emission reduction in coal mining area. And through the analysis of simulation results...
متن کاملSaving money, saving lives.

As a result, some caregivers felt that the quality of care had deteriorated. Parents' complaints were on the rise. Frustrated staff members were quitting. In this article, Jon Meliones, DCH's chief medical director, candidly describes how his debt-ridden ho...
متن کاملElectronic Medical Records: Saving Trees, Saving Lives
CONSIDER THIS IRONY OF MODERN LIFE: IN A MEDICAL CRISIS, EMERGENCY physicians would have an easier time accessing a patient’s bank account using his or her automatic teller machine card than they would finding critical medical history using his or her medical insurance card. Medical records, including crucial electrocardiograms, drug allergies, or medical conditions, are typically stored on pap...
متن کاملRetirement plans, personal saving, and saving adequacy.
This Issue Brief addresses three questions raised by recent trends in personal saving: How are national savings measured and what is the meaning of the trends in measured personal saving rates, given what is included and what is not included in those measures? What is the effect of retirement saving programs--in particular, 401(k) plans and individual retirement accounts (IRAs)--on personal sav...
