Ruggedness and robustness testing

Journal of Chromatography A, 2007
Due to the strict regulatory requirements, especially in pharmaceutical analysis, analysis results with an acceptable quality should be reported. Thus, a proper validation of the measurement method is required. In this context, ruggedness and robustness testing becomes increasingly more important.

Nested designs in ruggedness testing

Journal of Pharmaceutical and Biomedical Analysis, 1999
Nested designs were performed in order to execute a ruggedness test according to the United States Pharmacopeia definition for ruggedness, in which mainly non-procedure related factors are examined. Several nested designs have been executed on a high performance liquid chromatography assay to determine tetracycline and related substances in bulk ...

Guidance for robustness/ruggedness tests in method validation

Journal of Pharmaceutical and Biomedical Analysis, 2001
This paper is intended to give guidance in setting-up and interpreting a robustness test. The different steps in a robustness test are discussed and illustrated with examples. The recommendations given for the different steps are based on approaches found in the literature, several case studies performed by the authors and discussions of the authors ...

Ruggedness Improvement by Protection

2006 Bipolar/BiCMOS Circuits and Technology Meeting, 2006
Cellular phone power amplifier transistors have to withstand extreme voltages, temperatures and currents. Requirements on IC and packaging technology are relaxed by using over-voltage and over-temperature protection. To avoid breakdown, protection circuits are used that detect the collector peak voltage and die temperature to limit the output power ...

Neutrality and ruggedness in robot landscapes

Proceedings of the 2002 Congress on Evolutionary Computation. CEC'02 (Cat. No.02TH8600), 2003
The twin fitness landscape properties of neutrality and ruggedness are crucial to the dynamics of evolutionary optimisation. In this paper, we investigate the interplay between these two properties in a complex evolutionary robotics fitness landscape, through the introduction of four robot controller architecture models; the GasNet, uniform, dispersed ...

Improving the short circuit ruggedness of IGBTs

Microelectronics Reliability, 2016
Abstract The demands on reliable and fault tolerant power electronic devices are increasing. One opportunity to increase the IGBT short circuit ruggedness is to modify the thermal capacitance and the thermal resistance close to the chip and hence extend the possible short circuit duration. Therefore simulations with different metallization, bond wire

Ruggedized ceramic vidicon

IEEE Transactions on Electron Devices, 1967
A one-inch vidicon capable of withstanding sterilization treatments and severe environmental testing has been developed for space applications. The tube uses electrostatic focusing and magnetic deflection provided by photoetched deflection coils. The brazed ceramic-and-metal structure has an indium-sealed faceplate and is potted in a magnetic shield ...

Ballast Resistor Temperature Effect and Ruggedness

2019 IEEE BiCMOS and Compound semiconductor Integrated Circuits and Technology Symposium (BCICTS), 2019
The temperature and self-heating behavior of multiple ballast resistor devices structure was examined with the observation that a silicided polysilicon resistor sitting on top of thick oxide has greater self-heating characteristics with little heat dissipated into the substrate. Conversely the same device structure sitting on top of thin oxide has less

Ruggedization of MXM graphics modules

2012 IEEE Conference on High Performance Extreme Computing, 2012
MXM modules, used to package graphics processing devices for use in benign environments, have been tested for use in harsh environments typical of deployed defense and aerospace systems. Results show that specially mechanically designed MXM GP-GPU modules can survive these environments, and successfully provide the enormous processing capability ...
