Forecasting industrial emissions: a monetary approach

Yang DONG, Yi LIU, Jining CHEN, Yebin DONG, Benliang QU

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 5,   Pages 734-742 doi: 10.1007/s11783-012-0451-6

Abstract: Forecasts of industrial emissions provide a basis for impact assessment and development planning. To date, most studies have assumed that industrial emissions are simply coupled to production value at a given stage of technical progress. It has been argued that the monetary method tends to overestimate pollution loads because it is highly influenced by market prices and fails to address spatial development schemes. This article develops a land use-based environmental performance index (L-EPI) that treats the industrial land areas as a dependent variable for pollution emissions. The basic assumption of the method is that at a planning level, industrial land use change can represent the change in industrial structure and production yield. This physical metric provides a connection between the state-of-the-art and potential impacts of future development and thus avoids the intrinsic pitfalls of the industrial Gross Domestic Product-based approach. Both methods were applied to examine future industrial emissions at the planning area of Dalian Municipality, North-west China, under a development scheme provided by the urban master plan. The results suggested that the L-EPI method is highly reliable and applicable for the estimation and explanation of the spatial variation associated with industrial emissions.

Spatial Nonlinear Analysis of the Reasonable Cable Tension for a Thousand-meter Scale Cable-stayed Bridge

Zhang Jianmin,Xiao Rucheng

Strategic Study of CAE 2004, Volume 6, Issue 12,   Pages 37-42

Abstract:

In this paper, a model for spatial nonlinear optimization programming to obtain the prestresses of cables in the cable-stayed bridge is established, in which the bending strain energy of the beams for the bridge and the cable tower is the objective function, and structural stresses and the cable forces are the constraint conditions. In order to determine the prestresses of the cables of the bridge, the first order optimization method is used to solve the program. This method is used to obtain set of optimal cable tensions of a thousand-meter scale cable-stayed bridge under permanent loads, and the result of analysis showed that the method is easy to apply and effective.
