In situ microviscoelastic measurements by polarization interferometryWilliams, Valorie Sharron, 1960- January 1988 (has links)
A new type of computer-controlled instrument has been developed to measure microviscoelastic properties of thin materials. It can independently control and measure indentation loads and depths in situ revealing information about material creep and relaxation. Sample and indenter positions are measured with a specially designed polarization interferometer. Indenter loadings can be varied between 0.5 and 10 grams and held constant to ±41 mg. The resulting indentation depths can be measured in situ to ±1.2 nm. The load required to maintain constant indentation depths from 0.1 to 5.0 microns can be measured in situ to ±3.3 mg and the depth held constant to ±15 nm.

RAPIDLY ADAPTABLE INSTRUMENTATION TESTER (RAIT)Vargo, Timothy D. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Emerging technologies in the field of "Test & Measurement" have recently enabled the development of the Rapidly Adaptable Instrumentation Tester (RAIT). Based on software developed with LabVIEW®, the RAIT design enables quick reconfiguration to test and calibrate a wide variety of telemetry systems. The consequences of inadequate testing could be devastating if a telemetry system were to fail during an expensive flight mission. Supporting both open-bench testing as well as automated test sequences, the RAIT has significantly lowered total time required to test and calibrate a system. This has resulted in an overall lower per unit testing cost than has been achievable in the past.

Use of annular subapertures with focus control for testing rotationally symmetric optical systems.Liu, Ying-Moh Edward. January 1987 (has links)
A subaperture configuration to test aspheric optical components or systems is developed. The method developed has potential for testing rotationally symmetric aspheres without the use of null lenses. The aperture is divided into annular subaperture regions and an interferometer is refocused for each region to reduce the fringe density. Essential mathematical treatments involving annular subapertures, such as annular Zernike polynomials, are provided in detail. Numerical and experimental validations of the algorithm are described. Tolerance analyses on subaperture measurements are given. Computer programs were written to link the subaperture Zernike coefficients and to determine the full-aperture Zernike coefficients.

Analytical Scenario of Software Testing Using Simplistic Cost ModelBathla, Rajender, Kapil, Anil 15 February 2012 (has links)
Software testing is the process of executing a program with
the intention of finding errors in the code. It is the process
of exercising or evaluating a system or system component
by manual automatic means to verify that it satisfies
specified requirements or to identify differences between
expected and actual results [4]. Software Testing should not
be a distinct phase in System development but should be
applicable throughout the design development and
maintenance phases. ‘Software Testing is often used in
association with terms verification & validation ‘Software
testing is the process of executing software in a controlled
manner, in order to answer the question: Does the software
behave as specified. One way to ensure system‘s
responsibility is to extensively test the system. Since
software is a system component it requires a testing process
also. / Software can be tested either manually or automatically.
The two approaches are complementary: automated testing
can perform a huge number of tests in short time or period,
whereas manual testing uses the knowledge of the testing
engineer to target testing to the parts of the system that are
assumed to be more error-prone. Despite this contemporary,
tools for manual and automatic testing are usually different,
leading to decreased productivity and reliability of the
testing process. Auto Test is a testing tool that provides a
“best of both worlds” strategy: it integrates developers’ test
cases into an automated process of systematic contractdriven
testing.
This allows it to combine the benefits of both approaches
while keeping a simple interface, and to treat the two types
of tests in a unified fashion: evaluation of results is the
same, coverage measures are added up, and both types of
tests can be saved in the same format. The objective of this
paper is to discuss the Importance of Automation tool with
associate to software testing techniques in software
engineering. In this paper we provide introduction of
software testing and describe the CASE tools. The solution
of this problem leads to the new approach of software
development known as software testing in the IT world.
Software Test Automation is the process of automating the
steps of manual test cases using an automation tool or utility
to shorten the testing life cycle with respect to time.

On adaptive random testingKuo, Fei-Ching, n/a January 2006 (has links)
Adaptive random testing (ART) has been proposed as an enhancement to random
testing for situations where failure-causing inputs are clustered together. The basic
idea of ART is to evenly spread test cases throughout the input domain. It has
been shown by simulations and empirical analysis that ART frequently outperforms
random testing. However, there are some outstanding issues on the cost-effectiveness
and practicality of ART, which are the main foci of this thesis.
Firstly, this thesis examines the basic factors that have an impact on the faultdetection
effectiveness of adaptive random testing, and identifies favourable and
unfavourable conditions for ART. Our study concludes that favourable conditions
for ART occur more frequently than unfavourable conditions. Secondly, since all
previous studies allow duplicate test cases, there has been a concern whether adaptive
random testing performs better than random testing because ART uses fewer
duplicate test cases. This thesis confirms that it is the even spread rather than less
duplication of test cases which makes ART perform better than RT. Given that the
even spread is the main pillar of the success of ART, an investigation has been conducted
to study the relevance and appropriateness of several existing metrics of even
spreading. Thirdly, the practicality of ART has been challenged for nonnumeric or
high dimensional input domains. This thesis provides solutions that address these
concerns. Finally, a new problem solving technique, namely, mirroring, has been
developed. The integration of mirroring with adaptive random testing has been
empirically shown to significantly increase the cost-effectiveness of ART.
In summary, this thesis significantly contributes to both the foundation and the
practical applications of adaptive random testing.
