Wake Forest Magazine [Fall 2025]
No full textThe Wake Forest Magazine Fall 2025 issue explores how the university community connects with the natural world through stories of alumni, faculty, staff, and students. The feature theme, “How We Are Nurtured by Nature,” highlights the physical, emotional, and spiritual benefits of spending time outdoors. Articles include student reflections on favorite campus spots, alumni engaging in adventurous activities such as kayaking, cycling, hiking, skydiving, and spearfishing, and faculty discussions on the psychological and environmental importance of nature. The issue also features updates from President Susan R. Wente and coverage of Wake Forest’s Flow House in Vienna, celebrating 25 years of study abroad. Through essays, interviews, and photography, the magazine illustrates how time in nature fosters mindfulness, community, and well-being within the Wake Forest family

R-WAKE - System release 2 document
No full textThis report represents deliverable D4.2 “System Release 2” of the R-WAKE project, which describes the final system resulting from WP4 (System Development) intended to support the research
objectives and scope to be addressed as central task of WP5 (Simulation and Analysis). WP5 stands as the user of the system, with the central objective of providing an evidence-based proposal for
either maintaining current separation-standards, or adopting new potential separation
improvements, that is, the R-WAKE Concept(s) to be further investigated. The report includes an
update of the research objectives and scope, in terms of research questions and targeted study
scenarios, which incorporates the recommendations discussed during the mid-term review of the
project.

R-WAKE - System Release 1 Document
No full textThis report is the Deliverable 4.1 R-WAKE Release 1 Document, resulting from half of WP4 activities. It provides details on the early results regarding the simulation framework and validation activities, as described in previous deliverables D2.1, D2.2, D2.3, and D3.1. In this document, together with other documents attached as annexes, three main topics are addressed: 1) the implementation status of the software tool for the micro-analysis of en-route wake vortex encounters and the level of confidence of its outputs; 2) the execution of the safety assessment to define a preliminary version of the Severity Matrix (the first tangible outcome of the project); and 3) the implementation status of the simulation framework for the macro-analysis of the project.

R-WAKE - Scenario definition document
No full textThis report is Deliverable 2.3 Scenario Definition Document of the R-Wake project, resulting from
WP2 activities. It provides the detailed methodology and definition of scenarios to be simulated and
analysed in WP5 to generate the new knowledge and evidences of the level of risk and safety due to
en-route wake vortex encounters (WVEs) hazards, and to support the proposal of enhancements of
separation standards and methods to mitigate that hazards.
The scenarios definition elaborates further the research approach identified in deliverable D2.1
System Specification, based in two steps: Step-1 focusses on micro scale modelling, in order to assess
the WVE severity level and to obtain a Tolerability Risk Matrix (Safety case baseline); Step-2 focusses
on macro-scale modelling of a number of ECAC-wide scenarios, in order to assess the risk and safety
level in terms of probability (frequency) of events and mitigation, combining different patterns of
traffic demand and ATM constraints, and different types of separation standards and mitigation
methods.

Acoustic properties of aircraft wake vortices
No full textThe noise generation by aircraft wake vortices has been studied numerically and experimentally. The numerical study revealed a relation between the circulation Γ, the vortex core size rc and the frequency fa of the peak level in the vortex noise spectra, fa ≈ Γ/(2π rc)2. The experimental data were obtained in measurements at airports applying phased microphone arrays. It has been revealed that sound sources are closely located to the vortex cores. The focused noise spectra of the wake vortices of all measured aircraft types are dominated by two maxima. The second maximum at f = 100 Hz is clearly caused by wake vortices. The origin of the first at 12 Hz has not been identified. Wake vortices were acoustically detected in 80 percent of the flyovers. Lowest detection rates were observed for the newer aircraft types Airbus 319, 320 and Boeing 737-800. A comparison of the wake trajectories obtained by phased microphone arrays and LIDAR revealed that the detection capability of the latter is superior
