Gearboxes are mechanical devices used to transfer energy. These devices are located at the junction of a power shaft and motor. Gearboxes are used in applications that involve power transfers. These devices are classified based on the construction and arrangement of gears. Their operability also differ based on these configurations. Precision and standard are the main types of gearboxes. The global industrial gearbox market will grow steadily during 2014-2019 at a CAGR of 5.41% in terms of revenue. APAC dominated the market in 2014, followed by EMEA and the Americas.

UPS systems provide emergency power when the main power fails. It is used to protect equipment and machinery from unexpected power disruptions that could otherwise result in loss of productivity. UPS systems are of two types: online and offline. Online/double conversion UPS The online UPS is a double conversion system in which batteries are connected to an inverter to avoid power-transfer switches. The primary advantage of the online UPS is its ability to provide constant power and avoid momentary power lapses.

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.
