Testing Strategies for Model-Based Development - Bog af Mats P Heimdahl - Paperback

Testing Strategies for Model-Based Development - Bog af Mats P Heimdahl - Paperback

This report presents an approach for testing artifacts generated in a model-based development process. This approach divides the traditional testing process into two parts: requirements-based testing (validation testing) which determines whether the model implements the high-level requirements and model-based testing (conformance testing) which determines whether the code generated from a model is behaviorally equivalent to the model. The goals of the two processes differ significantly and this report..

Environmental Testing of the Next Pm1 Ion Engine - Bog af John S Snyder - Paperback

Environmental Testing of the Next Pm1 Ion Engine - Bog af John S Snyder - Paperback

The NEXT propulsion system is an advanced ion propulsion system presently under development that is oriented towards robotic exploration of the solar system using solar electric power. The Prototype Model engine PM1 was subjected to qualification-level environmental testing to demonstrate compatibility with environments representative of anticipated mission requirements. Random vibration testing, conducted with the thruster mated to the breadboard gimbal, was executed at 10.0 Grms for 2 minutes in..

Trmm Observations of Polarization Difference in 85 Ghz - Information about Hydrometeors and Rain Rate - Bog af C Prabhakara - Paperback

Trmm Observations of Polarization Difference in 85 Ghz - Information about Hydrometeors and Rain Rate - Bog af C Prabhakara - Paperback

Observations made by the Precipitation Radar (PR) and the Microwave Imager (TMI) radiometer on board the Tropical Rainfall Measuring Mission (TRMM) satellite help us to show the significance of the 85 GHz polarization difference, PD85, measured by TMI. Rain type, convective or stratiform, deduced from the PR allows us to infer that PD85 is generally positive in stratiform rain clouds, while PD85 can be markedly negative in deep convective rain clouds. Furthermore, PD85 increases in a gross manner..

Space Telecommunications Radio System (Strs) Compliance Testing - Bog af Louis M Handler - Paperback

Space Telecommunications Radio System (Strs) Compliance Testing - Bog af Louis M Handler - Paperback

The Space Telecommunications Radio System (STRS) defines an open architecture for software defined radios. This document describes the testing methodology to aid in determining the degree of compliance to the STRS architecture. Non-compliances are reported to the software and hardware developers as well as the NASA project manager so that any non-compliances may be fixed or waivers issued. Since the software developers may be divided into those that provide the operating environment including the..

Ed465 243 - Test and Measurement Expert Opinions - A Dialogue about Testing Students with Disabilities Out of Level in Large-Scale Assessments. Out-Of

Two focus groups of test and measurement experts were held to explore the use of out-of-level testing for students with disabilities. The participants (n=17) included state and federal level assessment personnel, test company employees, and university professors. A content analysis of the narrative results indicated that there was no clear consensus in supporting or not supporting out-of-level testing. Instead, focus group participants were able to adopt numerous perspectives on many contentious..

New Method for Dual-Axis Fatigue Testing of Large Wind Turbine Blades Using Resonance Excitation and Spectral Loading - Bog - Paperback

New Method for Dual-Axis Fatigue Testing of Large Wind Turbine Blades Using Resonance Excitation and Spectral Loading - Bog - Paperback

The blades of a wind turbine are generally considered to be the most critical component of the wind turbine system. The fundamental purpose of performing fatigue tests on wind turbine blades is to demonstrate that a blade, when manufactured to a certain set of specifications, has the prescribed reliability and service life. The purpose of the research conducted for this project is the advancement of knowledge and capabilities in the area of wind turbine blade fatigue testing.

Construction, Geology, and Aquifer Testing of the Maalo Road, Aahoaka Hill, and Upper Eleele Tank Monitor Wells, Kauai, Hawaii - Usgs Open-File Report

Construction, Geology, and Aquifer Testing of the Maalo Road, Aahoaka Hill, and Upper Eleele Tank Monitor Wells, Kauai, Hawaii - Usgs Open-File Report

The Maalo Road, Aahoaka Hill, and Upper Eleele Tank monitor wells were constructed using rotary drilling methods between July 1998 and August 2002 as part of a program of exploratory drilling, aquifer testing, and hydrologic analysis on Kauai. Aquifer tests were conducted in the uncased boreholes of the wells. The Maalo Road monitor well in the Lihue Basin penetrated 915 feet, mostly through mafic lava flows. Most of the rock samples from this well had chemical compositions similar to the Koloa Volcanics,..

Crash Testing German Banks - Bog - Paperback

Crash Testing German Banks - Bog - Paperback

In this paper we stress-test credit portfolios of twenty-eight German banks based on a Merton-type multifactor credit-risk model. The stress scenario is an economic downturn in the automobile sector. Although the percentage of loans in the automobile sector is relatively low for all banks in the sample, the expected loss conditional on the stress event increases substantially by 70-80 percent for the total portfolio. This result confirms the need to account for hidden sectoral concentration risk..
