Reforming project management: the role of lean construction
Presentation / Conference
Howell, G., & Koskela, L. Reforming project management: the role of lean construction. Presented at 8th Annual Conference of the International Group for Lean Construction, Brighton, UK

Project management as taught by professional societies and applied in current practice must be reformed because it is inadequate today and its performance will continue to decline as projects become more uncertain, complex and pressed for speed. Proj... Read More about Reforming project management: the role of lean construction.

The prevalent theory of construction is a hindrance for innovation
Presentation / Conference
Koskela, L., & Vrijhoef, R. The prevalent theory of construction is a hindrance for innovation. Presented at 8th Annual Conference of the International Group for Lean Construction, Brighton, UK

It is argued that construction innovation is significantly hindered by the prevalent theory of construction, which is implicit and deficient. There are three main mechanisms through which this hindrance is being caused.
Firstly, because production t... Read More about The prevalent theory of construction is a hindrance for innovation.

Motor current signal analysis using a modified bispectrum for machine fault diagnosis
Presentation / Conference
Gu, F., Shao, Y., Hu, N., Fazenda, B., & Ball, A. Motor current signal analysis using a modified bispectrum for machine fault diagnosis. Presented at ICROS-SICE International Joint Conference 2009, Fukuoka, Japan

This paper presents the use of the induction motor current to identify and quantify common faults within a two-stage reciprocating compressor. The theoretical basis is studied to understand current signal characteristics when the motor undertakes a v...

Gearbox fault diagnosis under different operating conditions based on time synchronous average and ensemble empirical mode decomposition
Presentation / Conference
Guan, L., Gu, F., Shao, Y., Fazenda, B., & Ball, A. Gearbox fault diagnosis under different operating conditions based on time synchronous average and ensemble empirical mode decomposition. Presented at ICROS-SICE International Joint Conference 2009, Fukuoka, Japan

In this paper, a new method is proposed by combining ensemble empirical mode decomposition (EEMD) with order tracking techniques to analyse the vibration signals from a two stage helical gearbox. The method improves EEMD results in that... Read More about Gearbox fault diagnosis under different operating conditions based on time synchronous average and ensemble empirical mode decomposition.
