Beta-testing

Design validation may take the form of qualification tests which stress the product up to and beyond design limits - beta tests where products are supplied to several typical users on trial in order to gather operational performance data, performance trials, and reliability and maintainability trials where products are put on test for prolonged periods to simulate usage conditions. 

Other examples are beta tests or public testing conducted on software products where tens or hundreds of products are distributed to designated customer sites for trials under actual operating conditions before product launch. Sometimes, commercial pressures force termination of these trials and products are launched prematurely in order to beat the competition. 

Conversely, the risks taken by the soldiers that now have Gulf War Syndrome were unnecessary. Beta testing of new technologies should have been done and should still be done before those new technologies enter the field. Because of classification and other problems, there is no peer review, leaving no one to stop...

Other applications include industrial safety monitoring, primarily in semiconductor plants, metals processing and hydrogen generation plants. A series of agreements for beta testing are in negotiation for these markets. 

CRADA) between the U.S. FDA and MultiCASE. It was designed to improve the prediction of the carcinogenic potential of pharmaceuticals. Matthews and Contrera (1998) performed a beta-test evaluation utilizing 126 compounds not included in the test database with 934 compounds. The results demonstrated an improvement in all statistical parameters for the prediction of carcinogenicity compared to the MultiCASE prediction with an overall concordance of 75 % (Patlewicz et al. 2003). 

Initial and snbseqnent commercial software product releases should only be used once they have been proven over a period of time by a nser community to be ht for pnrpose. It is recommended that software not be nsed nntil it has been commercially available for at least 6 months. Software prodncts released by a snpplier that are pending final evalnation (so-called beta testing of software) must NOT be used to support the manufacture of drug and healthcare products ... 

Beta Testing FDA (1995) Acceptance testing performed by the customer in a live application of the software at one or more end user sites in an environment not controlled by the developer. 

InChl (pronounced In-chee called IChl until 2004) stands for lUPAC International Chemical Identifier, and was developed to enable the easy linking of diverse data compilations, whether print or electronic. The name InChF is protected, but use and development of InChl identifiers is free access, and the source code and associated documentation can be downloaded for free from www. iupac.org/inchi. Source codes can be modified under the terms of a public licence, and lUPAC welcomes proposals for enhancements. Following beta-testing, the current version (1.02) is full release (January 2009). 

After the current beta-testing phase, the first official OASIS4 version will become available to the public in 2008. 

Based on the proven track record and widespread applicability of the CPE/CCP approach, EPA s Office of Research and Development/Center for Environmental Research Information decided in 1988 to fund development of an expert system to incorporate the expertise embodied in the CPE/CCP methodology. This report describes the concept, design, and implementation of this expert system. The system, POTW EXPERT, was beta-tested in September, 1989, and is currently in limited-distribution testing by EPA. 

The study was conducted at multiple Air Force installations. Dyess AFB, TX, served as the beta test site for participant selection, specimen collection, and exposure assessment. The lessons learned from the Dyess AFB beta test allowed the JP8 Research Team to improve data collection processes and study logistics, thus reducing the operational study impact at other Air Force bases involved in the study. Data was collected at the following sites Davis Monthan AFB, AZ, Seymour Johnson AFB, NC, Langley AFB, VA, Pope AFB, NC, Little Rock AFB, AR, and Hurlbert Field, FL. Specimens and data...

Markush DARC, with a test database of 1321 compounds drawn from INPI and Derwent indexing, went into beta-test on 26 May 1987. We estimate that these 1321 compounds represent, conservatively, four million individual chemical compounds. Considering that the test database represents only five weeks of input data, the possibilities for the future are astounding, if not a bit unnerving.
