The process of engineering software-intensive systems that comply with their Certification and Accreditation (C&A) requirements involves many critical decision-making activities for the related stakeholders. Considering the exhaustive nature of C&A activities together with the complexity of software-intensive systems, effective decision making relies heavily on the ways to understand and struct...

Existing taxonomies are valuable input for creating ontologies, because they reflect some degree of community consensus and contain, readily available, a wealth of concept definitions plus a hierarchy. However, the transformation of such taxonomies into useful ontologies is not as straightforward as it appears, because simply taking the hierarchy of concepts, which was originally developed for ...

The paper presents the analysis of software tools for generating parsers, based on Python language. Two main categories are distinguished: general-purpose languages not tied to a particular programming language and tools, developed exclusively Detailed number most common parser generation was performed. Based ISO/IEC 2510 standard, characteristics generators were identified. selected include pe...

An approach for the analysis and management of multiple criteria critical infrastructure problems is put forth. Nuclear waste management involves complex tradeoffs under uncertainty. Among all waste either generated by nature or human activities, radioactive nuclear waste is the most toxic to human health and difficult to manage: it is known that some nuclear waste material will be radioactive ...

So far, it was unclear if social hierarchy could influence sensory or perceptual cognitive processes. We evaluated the effects of social hierarchy on these processes using a basic visual perceptual decision task. We constructed a social hierarchy where participants performed the perceptual task separately with two covertly simulated players (superior, inferior). Participants were faster (better...
