Testing the Effectiveness of Mobile Home Weatherization Measures in a Controlled Environment - The Seri Cmfert Project - Bog - Paperback

Testing the Effectiveness of Mobile Home Weatherization Measures in a Controlled Environment - The Seri Cmfert Project - Bog - Paperback

For several years the Solar Energy Research Institute has been testing the effectiveness of mobile home weatherization measures. During the winter of 1988-89, several weatherization measures were thermally tested on three mobile homes under controlled conditions inside a large environmental enclosure. The effects of each weatherization measure on conduction losses, infiltration losses, and combined furnace and duct-delivered heat efficiency were monitored. The study demonstrated that cost-effective..

Baseline Testing of Ultracapacitors for the Next Generation Launch Technology (Nglt) Project - Bog af Dennis J Eichenberg - Paperback

Baseline Testing of Ultracapacitors for the Next Generation Launch Technology (Nglt) Project - Bog af Dennis J Eichenberg - Paperback

The NASA John H. Glenn Research Center initiated baseline testing of ultracapacitors for the Next Generation Launch Transportation (NGLT) project to obtain empirical data for determining the feasibility of using ultracapacitors for the project. There are large transient loads associated with NGLT that require either a very large primary energy source or an energy storage system. The primary power source used for these tests is a proton exchange membrane (PEM) fuel cell. The energy storage system..

Finance and Economics Discussion Series - Testing for Market Discipline in the European Banking Industry: Evidence from Subordinated Debt Issues - Bog

Finance and Economics Discussion Series - Testing for Market Discipline in the European Banking Industry: Evidence from Subordinated Debt Issues - Bog

The question of whether private investors can rationally discriminate between the risk taken by banks is empirically investigated by testing the risk sensitivity of European banks' subordinated notes and debentures (SND) spreads. A unique dataset of issuance spreads, issues and issuers rating, accounting and market measures of bank risk is used for a sample of European banks' SND issued during the 1991-2000: Q1 period. Moody's Bank Financial Strength (MBFS) and FitchIBCA Individual (FII) ratings..

Power Performance Test Report for the Southwest Windpower Air-X Wind Turbine - Bog - Paperback

Power Performance Test Report for the Southwest Windpower Air-X Wind Turbine - Bog - Paperback

In the period from 14 October 2002 to 16 January 2003, an early production version of Southwest Windpower's AIR-X turbine was installed at the NWTC test site for acoustic noise testing. In addition to the signals required for the noise testing, additional instrumentation that allowed power performance testing in accordance with IEC 61400-12 [1] was added. The results of that test are described in this report. Please note that this test and the test report are not an accredited power performance test/test..

Gearbox Reliability Collaborative Gearbox 1 Failure Analysis Report - December 2010 - January 2011 - Bog - Paperback

Gearbox Reliability Collaborative Gearbox 1 Failure Analysis Report - December 2010 - January 2011 - Bog - Paperback

Unintended gearbox failures have a significant impact on the cost of wind farm operations. In 2007, NREL initiated the Gearbox Reliability Collaborative (GRC). The project combines analysis, field testing, dynamometer testing, condition monitoring, and the development and population of a gearbox failure database in a multi-pronged approach to determine why wind turbine gearboxes do not achieve their expected design life. The collaborative of manufacturers, owners, researchers, and consultants focuses..

Ballistic Missile Defense - Improvements Needed in Thaad Acquisition Planning: Nsiad-97-188 - Bog - Paperback

GAO reviewed the Theater High Altitude Area Defense (THAAD) program to determine whether: (1) planned testing would demonstrate operational effectiveness before a significant number of units are produced for deployment; and (2) missile target resources are adequate to support testing plans. GAO noted that: (1) the current THAAD program review and evaluation provides the Department of Defense (DOD) with the opportunity to: (a) reduce risk and minimize the number of initial quantities of unproven system..

Gearbox Reliability Collaborative Bearing Calibration - Bog - Paperback

Gearbox Reliability Collaborative Bearing Calibration - Bog - Paperback

NREL has initiated the Gearbox Reliability Collaborative (GRC) to investigate the root cause of the low wind turbine gearbox reliability. The GRC follows a multi-pronged approach based on a collaborative of manufacturers, owners, researchers and consultants. The project combines analysis, field testing, dynamometer testing, condition monitoring, and the development and population of a gearbox failure database. At the core of the project are two 750kW gearboxes that have been redesigned and rebuilt..

Testing and Optimization of Electrically Conductive Spacecraft Coatings - Bog af R J Mell - Paperback

Testing and Optimization of Electrically Conductive Spacecraft Coatings - Bog af R J Mell - Paperback

This is the final report discussing the work done for the Space Environments and Effects (SEE) Program. It discusses test chamber design, coating research, and test results on electrically thermal control coatings. These thermal control coatings are being developed to have several orders of magnitude higher electrical conductivity than most available thermal control coatings. Most current coatings tend to have a range in surface resistivity from 1,011 to 1,013 ohms/sq. Historically, spacecraft have..
