Quantifying resilience in hydraulic engineering: Floods, flood records, and resilience in urban areas

open access: yesWIREs Water, Volume 7, Issue 3, May/June 2020., 2020
Resiliencein flood risk management is embedded in the emergency management life cycle. The flood incident is accompanied by operational measures of flood protection (response) and followed by a recovery phase inwhich the bounce back will hopefully take place or is organized by suitable measures.

Dynamic Model for Scheduling Crew Shifts

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
In regular as well as nonscheduled air transport, extraordinary situations occasionally occur, which may fundamentally disrupt the flight schedule. Fundamental disruptions of flight schedules affect not only passengers but also the airline. One of the areas that are negatively affected by the disruption is the crew plan. Due to extraordinary events, it

Methods for multicriterial selection of optimal routes in communication networks

open access: yesEastern-European Journal of Enterprise Technologies, 2019
Традиційно задачі маршрутизації у мережах зв’язку вирішуються на основі скалярного підходу, при якому враховуються тільки один показник якості. Однак передача інформації у мережах зв’язку характеризується сукупністю показників якості. Тому для отримання оптимального рішення задачі маршрутизації у мережах зв’язку повинен бути використаний ...

Environmental Quality Index of Urban Forest Remnants From Soil Analysis and Leaf Area Index, in Campinas – Brazil

open access: yesEnvironmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Assessing soil quality in forest fragments is crucial for understanding ecosystem dynamics and guiding conservation strategies. This study evaluates soil properties (0–0.20m) and leaf area index (LAI) using principal component analysis (PCA) and the analytical hierarchy process (AHP) to identify key indicators of soil environmental quality ...
