航空操控面板组件在气垫船上的应用研究

由于气垫船船型较小、空间有限,通过采用航空操控面板组件,对驾控台上各控制面板进行集成优化,使其能更合理地利用空间。在有限空间内实现驾控台各面板夜间显示、集中调光、集中试灯、集中报警等功能,并统一外形及显示方式,以达到优化各面板显示及操作方式,改善驾驶员的操纵使用界面。该面板首次在气垫船上使用,为气垫船控制面板的未来发展方向进行探索和尝试。

A tool for calculating aircraft emissions and its application to Greek airspace

This paper quantifies the impact of aircraft emissions on local air quality and climate change. Aircraft emissions during the cruise cycle and the landing/take-off cycle are considered. A tool is developed that computes emission values using real-time air traffic data derived from various databases. Emissions include carbon dioxide, hydrocarbons, carbon monoxide and nitrogen oxides. The overall output is a detailed ‘emissions map’ of a given territory that enables the identification of critical emission spots including routes, airports, season, aircraft type and flight category. The method can be used for real-time monitoring of airline emissions and for policy analysis. The proposed tool and resulting outputs are illustrated in the case of the Greek airport system using domestic, international and overflights. Demand volatility driven mainly by tourism and its impact on emissions is assessed.

机场运营效率评价及影响因素分析对科学反映中国主要民用机场运营效率现状,实现中国民航业可持续发展,提高中国机场国际竞争力具有重要意义.本研究首先利用双重导向型DEA模型测算2006-2010年中国27个主要民用机场的运营效率,然后从宏观环境、行业与区域竞争及机场特征三个方面探索机场运营效率的影响因素.研究结果表明,2006-2010年中国主要民用机场的运营效率基本维持在较高水平;各机场的运营效率自2008年始均有不同程度的下降,且机场间运营效率的差异呈现逐年增大的趋势;腹地经济、机场规模、机场级别和一市多场等因素促进了机场运营效率的提升;区域竞争和行业竞争则不利于机场运营效率的提升.     

Factors Affecting Disaster Preparedness,Response, and Recovery Using the Community Capitals Framework

Abstract

Disaster research often focuses on how and why communities are affected by a discrete extreme event. We used the community capitals framework to understand how community characteristics influence their preparedness, response to, and recovery from successive or multiple disasters using the 1964 Good Friday Earthquake and the 1989 Exxon Valdez Oil Spill as case studies. This study assesses community response to these disasters by reviewing published literature on impacts to create profiles for six communities and by identifying community capitals before and during these disasters, and throughout the long-term recovery. While the presence of rich natural capitals commonly contributed resources to pre-disaster planning and long-term recovery, restriction of resource access immediately following the disasters was detrimental to many communities. Communities with strong political, social, and financial capitals tended to fare better immediately following disasters, enabling longer-term processes of transformation or recovery. However, in some communities the oil spill undermined these capitals more than the earthquake and resulting tsunami. In understanding how use and reliance on community capitals can lead to varied recovery success from different kinds of disasters, these findings can help coastal managers and planners prepare for future disasters.
