Quantum-dot cellular automata (QCA) are one of the most promising alternative platforms of the future. Recent years have witnessed the development of basic logic structures as well as more complex processing structures, however most in the realm of binary logic. On the grounds that future platforms should not disregard the advantages of multi-valued logic, Lebar Bajec et al. were the first to show that quantum-dot cellular automata can be used for the implementation of ternary logic as well. In their study the ternary AND and OR logic functions proved to be the most troublesome primitive to implement. This research presents a revised solution that is based on adiabatic switching.

The rapid evolution of information and communications technologies has brought the potential held by urban analytics up to a higher level and thus promises more well-informed decisions, including advances in the assessment methodologies and monitoring based on existing data and its reuse. The paper provides an insight into an ongoing national research project examining the assessment methodologies and data integration for the purpose of monitoring the progress as regards sustainability and quality in urban environments. Specifically, we focus on the level of the neighbourhoods; by measuring the extent to which the built environment comprehends the required characteristics and configuration for efficiency, or contribute to quality living and sustainability. Current study covers the aspect of efficient mobility and connectivity, revealing the potential of the location-based data provided by mobile devices and associated infrastructures. While such data are widely recognised as a beneficial source of information in various fields and solid advances have been made in both analytics and modelling, little progresses has been seen in exploiting that potential as regards sustainability assessment tools. This study examines the viability of indicators addressing travel time reliability throughout the empirical testbed, exemplified by six strategic routes associated with three neighbourhoods in Ljubljana, Slovenia. The paper summarizes current progress of the study.   Received: 21 January 2021 / Accepted: 22 March 2021 / Published: 10 May 2021
