Path dependency and the future of advanced vehicles and biofuels 总被引:1,自引:0,他引:1
The accumulated experience and path-dependent development of petroleum-based transport fuels and internal combustion engine vehicles has created an apparent technological lock-in. Our analysis of a RApid Future vehicles and Fuels scenario (RAFF) for the EU shows that ambitious carbon emission reductions can be achieved even with projected increases in road transport. Furthermore, escaping the lock-in does not seem insurmountable. For this purpose, three strategic technology platforms should be supported: the electric drivetrain, the biochemical, and the thermo-chemical platforms. Each platform has its own characteristics and exhibits its own path dependencies that are relevant to consider with the aim of accelerating their development and application. Contrary to conventional wisdom indicating that governments should not pick winners, we argue that these three platforms should be subject to focused and concerted development efforts. They all offer advantages to transport as well as other applications, and they match low-carbon futures in which electricity and/or hydrogen are important energy carriers. 相似文献

This paper investigates the problem of robust H
∞ filtering for a class of uncertain nonlinear stochastic time-delay systems with Markovian jump parameters. The system under
consideration contains parameter uncertainties, It?-type stochastic disturbances, unknown nonlinearities as well as time-varying delays, which vary in a range and dependent
on the mode of the operation. We aim to design a full-order Markovian jump filter such that, for all admissible uncertainties,
the filtering error system is robustly asymptotically stable in the mean square, and a prescribed H
∞ disturbance attenuation level is guaranteed. By using the Lyapunov stability theory and It? differential rule, some sufficient conditions in terms of linear matrix inequality (LMI) are proposed to guarantee the existence
of the desired H
∞ filter. Then, the explicit expressions of the desired filter parameters are given. Illustrative examples are provided to
demonstrate the effectiveness and applicability of the proposed method. 相似文献

A survey of local planning officials in Southern California found that decision-making processes affect local residential development policy, despite prevailing views that local political forces are largely irrelevant. While most studies of local development policy rely on easily available, published measures of socioeconomic and institutional variables, this study used a comparative analysis of local governments. The results indicate that survey-based measures of local officials' attitudes and perceptions can account for variations in restrictions on local residential development, even after adjusting for the effects of socioeconomic characteristics. 相似文献
