Project pathogens: The anatomy of omission errors in construction and resource engineering project
Construction and engineering projects are typically
complex in nature and are prone to cost and schedule overruns.
A significant factor that often contributes to these overruns is rework.
Omissions errors, in particular, have been found to account
for as much as 38% of the total rework costs experienced. To date,
there has been limited research that has sought to determine the
underlying factors that contribute to omission errors in construction
and engineering projects. Using data derived from59 in-depth
interviews undertaken with various project participants, a generic
systemic causal model of the key factors that contributed to omission
errors is presented. The developed causal model can improve
understanding of the archetypal nature and underlying dynamics
of omission errors. Error management strategies that can be
considered for implementation in projects are also discussed
Video shot boundary detection: seven years of TRECVid activity
Shot boundary detection (SBD) is the process of automatically detecting the boundaries between shots in video. It is a problem which has attracted much attention since video became available in digital form as it is an essential pre-processing step to almost all video analysis, indexing, summarisation, search, and other content-based operations. Automatic SBD was one of the tracks of activity within the annual TRECVid benchmarking exercise, each year from 2001 to 2007 inclusive. Over those seven years we have seen 57 different research groups from across the world work to determine the best approaches to SBD while using a common dataset and common scoring metrics. In this paper we present an overview of the TRECVid shot boundary detection task, a high-level overview of the most significant of the approaches taken, and a comparison of performances, focussing on one year (2005) as an example
The Energy Babble in Experimental Practice: Provocations In and Out of Design
The Energy Babble device and documentary film featured in the following exhibition as part of the Melbourne International Design Festival:
'As an exhibition, round-table discussion and workshop, Experimental Practice: Provocations In and Out of Design investigated how new hybrid practices and collaborations were negotiating complex social and environmental challenges. The exhibition presented a number of projects in which art and design strived to make a difference within the specific communities in which they were situated. Curated by Katherine Moline (UNSW), Brad Haylock and Laurene Vaughan (RMIT), Experimental Practice was the second iteration of the exhibition and symposium Feral Experimental: New Design Thinking, shown at UNSW Galleries, Paddington, in 2014.’ This project was generously supported by UNSW Australia Art & Design, UNSW Galleries, the National Institute for Experimental Arts, RMIT School of Media and Communication, RMIT Design Research Institute and RMIT Design Futures Lab
Structural and gas-sensing properties of CuO–CuxFe3−xO4 nanostructured thin films
Nanocrystalline CuO–CuxFe3−xO4 thin films were developed using a radio-frequency sputtering method followed by a thermal oxidation process. Thin films were deposited applying two very different conditions by varying the argon pressure and the target-to-substrate distance. Structural, microstructural and gas-sensing characteristics were performed using grazing incidence X-ray diffraction (GXRD), Raman spectroscopy, atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and electrical measurements. Their sensing properties were examined using hydrogen gas in dry synthetic air. The shortest response and recovery times were observed between 280 and 300 °C independently of the deposition conditions
Vietnam’s trade policy: a developing nation assessment
Aim/PurposeThis paper is a review of the progress of the Vietnam socio-economic and development plan and an assessment of the extent to which Vietnam is putting in place the critical social and economic development structures that will enable it to reach the status of “developed nation” in the time set (2020) by its national strategic plan. The research will identify and review trade patterns, trade policy and the effect of foreign aid on Vietnam’s plan to transform its economy and society from a developing nation status to status of developednation. The overriding question stands as “is” Vietnam effec-tively moving towards developed nation statussoon”?BackgroundThis paper examines the history of Vietnam from the command economy in its transition to a market driven economy, the criteria, hurdles and challenges as the country moves towards a developed country status. MethodologyApplied research based on the body of research in socio-economic develop-ment theory, international trade and market theory. The review is conducted by collecting and analyzing data on foreign trade, foreign aid, business and general economic growth, development and social wellbeing. Itidentifies and appraises the trade patterns,trade effects, socio-economic policies and the effect of foreign aid] on the economic growth and the progress of the coun-try towards becoming a developed nation state
