11321.全球声纳系统市场报告(2015-2019年)
[计算机、通信和其他电子设备制造业] [2015-09-06]
The use of sonar by humans was first recorded by Leonardo da Vinci in 1490. Intense research on the concept of sonar technology as it is known today was prompted by the Titanic disaster of April 1912. During the World War I the need to detect submarines fueled more research for sonar development. Active sonar is used for civilian purposes like oil exploration activities, fishing, and hydrographic and nautical charting activities. Passive sonar is used in military activities. Active sonar generates a pulse of sound and listens for its reflections when the pulse hits an object. Passive sonar, on the other hand, listens without transmitting.

11322.环境管理体系(EMS)的目标和预算:2012年度业绩总结
[水利、环境和公共设施管理业] [2015-08-29]
Sandia National Laboratories/New Mexico's (SNL/NM) Environmental Management System is the integrated approach for members of the workforce to identify and manage environmental risks. Each Fiscal Year (FY) SNL/NM performs an analysis to identify environmental aspects, and the environmental programs associated with them are charged with the task of routinely monitoring and measuring the objectives and targets that are established to mitigate potential impacts of SNL/NMs operations on the environment. An annual summary of the results achieved towards meeting established objectives and targets provides a connection to, and rational for, annually revised environmental aspects. The purpose of this document is to summarize the results achieved and documented in FY2012.

The Carnegie Endowment for International Peace (CEIP), through its Leadership Initiative for Transportation Solvency, in 2011 released Road to Recovery: Transforming America's Transportation, a report that proposed a new revenue mechanism to fund a reformed transportation program fully. The report recommends that Congress couple a per barrel oil fee with a variable, countercyclical gas tax. This paper discusses the dynamic impacts of CEIP's revenue policy on household travel behavior, revenue generation for the federal trust fund, energy consumption, equity, and greenhouse gas (GHG) emissions and air pollution at the national level from 2008 to 2010. The analysis developed econometric models: a multiple vehicle miles traveled (VMT) regression model and a discrete vehicle ownership model. Model results showed that the CEIP revenue proposal could fill the revenue shortfall regardless of the world oil price. During the historic study period of 2008 to 2010, the CEIP policy would have collected up to more than double the federal revenue. At the same time, households would have increased their VMT by as much as 1.8% when oil prices peaked, and reduced their VMT by up to 8.6% when the crude oil price dropped to the lowest point. It is estimated that, without any investments or revenue recycling, lower-income households would have experienced a 0.45% to 0.5% reduction in consumer surplus changes measured as a percentage of income and higher-income households would have experienced a 0.06% to 0.1% reduction. Finally, it is estimated that the CEIP policy would have reduced air pollution and GHG emissions by an average 4% to 4.35% for different pollutant types.

MEA are advanced next-generation aircraft that use more electrical systems to reduce the nonpropulsive power systems such as mechanical, hydraulic, and pneumatic systems. This has resulted in a reduction in the weight of the aircraft, leading to a low cost of ownership, usage of less fuel, a reduction in emissions, increased reliability, and other added benefits.

[其他制造业] [2015-08-24]
Incineration is the process of combustion of organic and harmful substances present in municipal and industrial waste products. Incinerators are not only used as an effective waste management technique but can also be used for the generation of heat and electricity by the combustion of waste. The use of incinerators reduces 70% by mass and 90% by volume of the waste subjected to disposal. Moving grate, rotary kiln, static hearth, static furnace, multiple hearth, and fluidized bed are incinerators used by municipal and industrial sectors for waste disposal.
