An architecture of execution environment for context-aware applications running in intelligent space
(Wydawnictwa AGH, 2013) Nasiadka, Sławomir; Krawczyk, Henryk
Context-aware applications running in intelligent spaces are one of the most dynamically developed group of applications. Their model called CAA (Context-Aware Applications) on the one hand allows to express their interactivity with regard to cooperation with an intelligent space and their users. On the other hand it shows their iterative nature that allows to analyze context-aware part of the application according to iterative algorithms. Applications defined in that way can be executed directly be the intelligent space. However, to do that the space needs to be enhanced with a special engine delivering particular mechanisms. The article describes such engine called Parallel CAA, its architecture and implementation. The implementation creates a CAA execution environment.

Preferable ways of decision-making in IT teams
(AGH University of Science and Technology Press, 2019) Krawczyk-Bryłka, Beata; Krawczyk, Henryk
Software development team collaboration requires various decisions regarding essential aspects of a project's progress. General and particular decision-making models are considered, and their main aspects such as team types, problem solving categories, and decision-making ways are analyzed. The research concerns representative groups of IT specialists and their preferences in decision-making are investigated. Four possible cases were tested: hierarchical choice (by leader) team members' choice (team consensus or voting) and external expert impact. It allows one to show some differences in the behaviors of both traditional and virtual teams.
