Tripping Device Effects on the Turbulent Boundary Layer Development

AIAA AVIATION 2022 Forum, 2022
Tripping devices are commonly used in wind tunnel testing to hasten the boundary layer laminar-turbulent transition and mimic aerodynamic effects present in full-scale applications. However, the tripping device role in the transition process and in the developed turbulent boundary layer is still not fully understood.

MODERN STRUCTURAL STEELS WITH TRIP-EFFECT

Science and Transport Progress, 2021
Purpose. The aim of this work is to analyze the latest literature data on current state of the issue in the development of the chemical composition and heat treatment modes of steels that implement the TRIP effect under loading. Due to the deformation martensitic transformation of retained austenite, these steels have increased mechanical and ...

Multi-Destination and Multi-Purpose Trip Effects in the Analysis of the Demand for Trips to a Remote Recreational Site [PDF]

Environmental Management, 2009
One of the basic assumptions of the travel cost method for recreational demand analysis is that the travel cost is always incurred for a single purpose recreational trip. Several studies have skirted around the issue with simplifying assumptions and dropping observations considered as nonconventional holiday-makers or as nontraditional visitors from ...

Effect of austempering temperature on the microstructure and wear resistance of ultrafine bainitic steel

工程科学学报, 2018
Ultrafine bainitic steels, which are derived from nanostructured carbide-free bainitic steels, exhibit a remarkable combination of ultra-high strength and toughness together with excellent wear resistance. Their excellent integrated mechanical properties

Comparison of travel pattern before and during COVID-19 restrictions (ease and strict restrictions) in Greater Kuala Lumpur, Malaysia

Transportation Research Interdisciplinary Perspectives, 2023
Previous studies have investigated the effect of COVID-19 on travel behaviour, particularly on changing trends of daily trips and weekly trips for various trip purposes (work, shopping, recreational and social).

Effect of trip attributes on ridehailing driver trip request acceptance

CoRR
A generalized additive mixed model was estimated to investigate the factors that impact ridehailing driver trip request acceptance choices, relying on 200 responses from a stated preference survey in Seattle, US. Several policy recommendations were proposed to promote trip request acceptance based on ridehailing drivers willingness to accept ...

Influence of Microstructure on the Mechanical Properties and Work-Hardening Behavior of High-Carbon Nanostructured Bainitic Steel [PDF]

Archives of Metallurgy and Materials
The microstructure-properties relationship of the low-alloy, high-carbon nanostructured bainitic steel obtained by heat treatment, including austenitization and cooling followed by isothermal nanobainitic transformation at 280℃ for 72 h, was investigated.

Longitudinal Effects in the Effectiveness of Educational Virtual Field Trips

Journal of Educational Computing Research, 2021
Virtual and immersive virtual reality, VR and iVR, provide flexible and engaging learning opportunities, such as virtual field trips (VFTs). Despite its growing popularity for education, understanding how iVR compared to non-immersive media influences learning is still challenged by mixed empirical results and a lack of longitudinal research.

Microstructure And Texture Evolution During Cold-Rolling In The Fe-23Mn-3Si-3Al Alloy

Archives of Metallurgy and Materials, 2015
Fe–23wt.%Mn–3wt.%Si–3wt.%Al alloy was cast, homogenized at 1150ºC, hot-rolled at temperatures between 1200ºC and 900ºC and next cold-rolled from 5% up to 40% reductions in thickness.

Managing the effect of TRIPs on availability of priority vaccines

Bulletin of the World Health Organization, 2006
The stated purpose of intellectual property protection is to stimulate innovation. The Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) requires all Members of the World Trade Organization (WTO) to enact national laws conferring minimum standards of intellectual property protection by certain deadlines.
