To explore the method of creating a theoretical model of urban low-carbon economy evaluation, and analyze the development status and level of low carbon economy in cities in the middle and lower reaches of Yangtze River; Method To introduce the basic theory of low-carbon economy, the principle and the technical route for creating the evaluation system of urban low-carbon economy, develop 3 laye...

* Corresponding author. ABSTRACT Designing vehicles specifically for city use is a topic of increasing interest in the transportation community. Hybrid vehicle design typically seeks to maximize fuel economy subject to acceleration performance and other constraints, based upon the expected driving needs of the average user. Fuel economy predictions are inaccurate when the vehicle’s expected and...

For the shortage of the traditional evaluation methods of the urban economy, A new evaluation model proposed, establishing an index system of evaluation and decision table on city economy, and extracting important properties of input data from Rough Set and neural network, and evaluation indexes reduced as input of neural network to realize the city's economic strength evaluation , then, using ...

The economy of street food vendors provides not only affordable food for the urban poor people, but also generates opportunities of self-employment. However, success of these tiny units is dependent on various networks that create this economy. Therefore, economic outcomes from these entrepreneurial activities could be embedded with the social relations through networks. Through an ethnographic...

This paper presents the traction motor sizing for optimal urban fuel economy in two mild and three strong hybridization propulsion on front-wheel-drive vehicles. The traction motor sizes, by means of motor rated torque and speed, are optimized for maximum urban fuel economy. The two mild hybrids are Belt-Integrated-Starter-Generator (BISG) and Crankshaft-Integrated-Starter-Generator (C-ISG) sys...

Faced to the economic and energetic context of our society, it is widely recognised that an alternative to fossil fuels and oil-based products will be needed in the nearest future. In this way, development of urban biorefinery could bring many solutions to this problem. Study of the implementation of urban biorefinery highlights two sustainable configurations that provide solutions to the Wallo...

This emergy-based urban economic account provided a historical portrait of the urban economy and its structures to understand the overload of the biosphere`s assimilative capacity. The basic situation of the urban economy, involving the indigenous resources base, emergy consumption patterns, emergy exports and imports, were investigated, accounted and discussed. Using a series of ratios and ind...
