SODAR measurements of wing vortex strength and position
Journal Article
Bradley, S., Mursch-Radlgruber, E., & von Hünerbein, S. SODAR measurements of wing vortex strength and position. Journal of Atmospheric and Oceanic Technology, 24(2), 141-155. https://doi.org/10.1175/JTECH2037.1

A method is developed for robust real-time visualisation of aircraft vortex spatial and temporal development based on measurement data from a line array of SODARs. The method relies on using a potential-flow vortex model, with spatial averaging accor... Read More about SODAR measurements of wing vortex strength and position.

A systematic algorithm for obtaining SODAR wind profiles
Journal Article
Bradley, S., & von Hünerbein, S. A systematic algorithm for obtaining SODAR wind profiles. Meteorology and Atmospheric Physics, 85(1-3), 77-84. https://doi.org/10.1007/s00703-003-0035-x

Current methods of obtaining wind profiles from SODARs generally employ ad hoc strategies for Doppler spectrum peak selection, profile smoothing, and consistency checks. This paper addresses the problem of systematically obtaining vertical profiles o... Read More about A systematic algorithm for obtaining SODAR wind profiles.

Atmospheric acoustic interferometer tomography of temperature and winds
Presentation / Conference
Bradley, S., von Hünerbein, S., & Haddad, A. Atmospheric acoustic interferometer tomography of temperature and winds. Presented at International Workshop on Tomography and Acoustics, Leipzig, Germany

A technique is described for multiple-path propagation time measurements in the surface layer of the atmosphere. This is based on solving simple bi-directional ray tracing equations on successively higher penetrating paths using propagation times for...

The economic theory of production conceals opportunities for sustainability improvement
Presentation / Conference
Koskela, L., & Tommelein, I. The economic theory of production conceals opportunities for sustainability improvement. Presented at 17th Annual Conference of the International Group for Lean Construction, National Pingtung University of Science and Technology, LCI-Taiwan and LCI-Asia, The Grand Hotel, Taipei, Taiwan

In analyses of action options regarding sustainability, the economic theory of production is often used as a conceptual starting point. We contend that this theory is deficient, even counterproductive. Especially, we argue that effective options exis...

Analysis framework for the interaction between lean construction and building information modelling
Presentation / Conference
Sacks, R., Dave, B., Koskela, L., & Owen, R. Analysis framework for the interaction between lean construction and building information modelling. Presented at 17th Annual Conference of the International Group for Lean Construction, National Pingtung University of Science and Technology, LCI-Taiwan and LCI-Asia, The Grand Hotel, Taipei, Taiwan

Building with Building Information Modelling (BIM) changes design and production processes. But can BIM be used to support process changes designed according to lean production and lean construction principles? To begin to answer this question we pro...

Last planner system : experiences from pilot implementation in the Middle East
Presentation / Conference
Alsehaimi, A., Tzortzopoulos, P., & Koskela, L. Last planner system : experiences from pilot implementation in the Middle East. Presented at 17th Annual Conference of the International Group for Lean Construction, National Pingtung University of Science and Technology, LCI-Taiwan and LCI-Asia, The Grand Hotel, Taipei, Taiwan

The work described in this paper is devoted to evaluate the effectiveness of implementing Last Planner to improve construction planning practice in Saudi construction industry. Firstly, the primary results of implementing Last Planner System (LPS) in... Read More about Last planner system : experiences from pilot implementation in the Middle East.
