Recently, biometrics is used in many security systems and these systems can be located in different environments. As many experts claim and previous works have demonstrated, environmental conditions influence biometric performance. Nevertheless, there is not a specific methodology for testing this influence at the moment. Due to it is essential to carry out this kind of evaluations, a new ISO s...

Maintainability is typically described initially as a non functional requirement at the system level. Systems engineers must subsequently apportion these system requirements very carefully as either software or hardware requirements to conform to the maintainability requirements of the system. A number of concepts are provided in the ECSS, ISO 9126, and IEEE standards to describe the various ty...

To conduct Acceptance Sampling, companies often use plans that are determined by easy-touse standards. However, these standards do not take quality costs directly into account. Motivated by the case of a Greek company, which uses the Greek equivalent to the ISO 2859 (1974) for the quality control of its incoming raw materials, this paper aims at evaluating the single-sampling plans recommended ...

We frequently talk about the “quagmire” of process models and standards: ISO 9001, Software CMM, CMMI, ISO 12207, etc. There are valid reasons for the diversity of models and standards imposed on our software development and maintenance processes, just as there is a legitimate concern that a high overhead is imposed by customers and markets that require multiple models and standards as a condit...

The quality requirements of wood biofuels are regulated by a series of harmonized international standards. These standards define the technical parameter limits that influence the quality of solid biomass as a fuel. In 2014 the European reference standard for solid biofuel was replaced by the International ISO standard. In the case of wood chips, the main difference between the European and Int...
