Developing a more useful surface quality metric for laser optics

Quentin Turchette, Trey Turner, W. Andrew Clarkson, Norman Hodgson, Ramesh Shori
2011 Solid State Lasers XX: Technology and Devices  
Also, there is no clear correlation between inspection results and the actual performance impact of the optic in a laser resonator.  ...  Light scatter due to surface defects on laser resonator optics produces losses which lower system efficiency and output power.  ...  To understand how this situation arose, it's necessary to know the history of the surface quality specification.  ...

On the Sustained Use of a Test-Driven Development Practice at IBM

J.C. Sanchez, L. Williams, E.M. Maximilien
2007 Agile 2007 (AGILE 2007)  
The IBM team realized sustained quality improvement relative to a pre-TDD project and consistently had defect density below industry standards.  ...  Additionally, our data indicates that the use of TDD may decrease the degree to which code complexity increases as software ages, as measured by cyclomatic complexity metric.  ...  We would also like to thank members of the NC State University RealSearch research group for their help on the paper.

Revisiting the problem of using problem reports for quality assessment

Parastooi Mohagheghi, Reidar Conradi, Jon Arvid Børretzen
2006 Proceedings of the 2006 international workshop on Software quality - WoSQ '06  
To distinguish between terms such as defects or errors, we propose to answer three questions on the scope of a study related to what (problem appearance or its cause), where (problems related to software  ...  Some of these concerns could be settled by answering some basic questions related to the problem reporting fields and improving data collection routines and tools.  ...  In S5, we experienced that the size of software components (used to measure defect density) was not collected systematically on the date of a release.  ...

Transparent combination of expert and measurement data for defect prediction

Michael Kläs, Frank Elberzhager, Jürgen Münch, Klaus Hartjes, Olaf von Graevemeyer
2010 Proceedings of the 32nd ACM/IEEE International Conference on Software Engineering - ICSE '10  
Defining strategies on how to perform quality assurance (QA) and how to control such activities is a challenging task for organizations developing or maintaining software and software-intensive systems  ...  Combining expert opinion with commonly available measurement data in a hybrid way promises to overcome the weaknesses of purely data-driven or purely expert-based estimation methods.  ...  ACKNOWLEDGMENTS We would like to thank especially the members of the T-Mobile I&V department, where we conducted the case study.  ...

On the need for a process for making reliable quality comparisons with industrial data

Laurie Williams
2004 Software engineering notes  
The first is a case study of an IBM team that transitioned to the use of test-driven development. The primary quality measure was functional verification test defects normalized by lines of code.  ...  The second case study was performed with an Extreme Programming team at Sabre Airline Solutions. Both test defects and field defects were compared.  ...  One means of making this comparison is through a measure of defect density (defects/lines of code) of the resulting products.  ...

A case study comparing defect profiles of a reused framework and of applications reusing it

Anita Gupta, Jingyue Li, Reidar Conradi, Harald Rønneberg, Einar Landre
2008 Empirical Software Engineering  
In addition, the defect densities of the most severe defects of the reused framework are similar to those of the applications that are reusing it.  ...  The results reveal that the framework has a much lower defect density in total than one application and a slightly higher defect density than the other.  ...  Acknowledgements This work was financed in part by the Norwegian Research Council for the SEVO (Software EVOlution in Component-Based Software Engineering) project (SEVO 2004) with contract number 159916  ...

A Longitudinal Study of Static Analysis Warning Evolution and the Effects of PMD on Software Quality in Apache Open Source Projects [article]

Alexander Trautsch, Steffen Herbold, Jens Grabowski
2020 arXiv   pre-print
Despite this being a best practice in software development, there is still a lack of empirical research regarding the usage of ASATs in the wild.  ...  Regardless, if we consider defect density as a proxy for external quality, we see a positive effect if PMD is present in the build configuration of our study subjects.  ...  We also want to thank the GWDG Gttingen 14 , as without the usage of their HPC-Cluster the data collection would have taken decades.  ...

Cone Beam CT for Diagnosis and Treatment Planning in Trauma Cases

Leena Palomo, J. Martin Palomo
2009 Dental Clinics of North America  
CBCT equipment is smaller and less expensive than traditional medical CT equipment and is tailored to address challenges specific to the dentoalveolar environment.  ...  In hospital settings, it is common to use CT in patients with trauma and pathologic conditions. However, in dental practice, practitioners depend almost entirely on twodimensional plain films.  ...  In 1998, Mozzo and colleagues 1 reported on the NewTom 9000 (Quantitative Radiology, Verona, Italy), the first CBCT unit developed specifically for dental use.  ...
