Business process re-engineering using a customised mapping model: a case study in a SME
Zong, L.; Day, R. (2007)Increasing customer expectations in terms of cost, quality and services, together with competition in global markets has placed a premium on effective internal business processes. Companies are investing to streamline ... -
Closure to "Coupled and decoupled numerical modeling of flow and morphological evolution in alluvial rivers" by Zhixian Cao, Rodney Day, and Shinji Egashira
Cao, Z.X.; Day, R.; Egashira, S.J. (2003-09) -
Coupled and Decoupled Numerical Modeling of Flow and Morphological Evolution in Alluvial Rivers
Cao, Z.; Day, R.; Egashira, S. (2002) -
Culvert design guide
Day, R.; Ramsbottom, D.; Rickard, C. (CIRIA, 1997) -
Design considerations of scheduling systems suitable for PCB manufacturing
Fernandez-Flores, O.; Speer, T.; Day, R. (2009)This paper identifies five key design characteristics of production scheduling software systems in printed circuit board (PCB) manufacturing. The authors consider that, in addition to an effective scheduling engine, a ... -
Design, Commissioning and Control System of a Hybrid Rocket Test Cell
Wilkinson, R.; Hart, K.; Day, R. (AIAA, 2010)A rocket-motor test cell, capable of carrying out instrumented firings of hybrid and composite motors of up to 5kN (1100lb) thrust and up to 8 feet in length, has been installed at the University of Hertfordshire, UK. The ... -
Effect of tailwater depth and model scale on scour at culvert outlets
Day, R.; Liriano, S.L.; White, W.R. (2001) -
The Effectiveness of the Land-Drainage Consent System
Day, R.; Fenner, R.A. (1996)This paper presents the results of a study into the effectiveness of the land-drainage consents system. The investigation studied eighteen main river reaches, each 2 km in length, in the north-east Thames region. All works ... -
Experimental observations of obstructions on floodplains
Liriano, S.L.; Marriott, M.J.; Day, R. (2001)The effect of placing obstructions of similar size but different shapes and at different locations on a floodplain adjacent to a meandering channel is considered. The results from the laboratory model tests show that placing ... -
Laboratory calibration of open channel bed resistance
Marriott, M.J.; Day, R. (2000)This paper deals with the calibration of bed resistance to flow in a straight open channel contained within a laboratory flume. The longitudinal slope of the flume was able to be varied, and so the flow could be subcritical ... -
Predicting scour downstream of culvert outlets using artificial neural networks
Liriano, S.L.; Day, R. (2000) -
Predicting the magnitude and position of maximum scour depth downstream of culvert outlets using artificial neural networks
Liriano, S.; Day, R. (2000-11) -
Predicting the magnitude and position of maximum scour depth downstream of culvert outlets using artificial neural networks.
Liriano, S.L.; Day, R. (2000) -
Prediction of scour depth at culvert outlets using neural networks
Liriano, S.L.; Day, R. (2001) -
Preliminary Observations of Turbulent Flow at Culvert Inlets
Day, R. (1997)This paper presents the results of preliminary observations of turbulence at the inlet to a pipe culvert using a bidirectional electromagnetic current meter (ECM). Instantaneous longitudinal and vertical components of ... -
Proof-of-Concept Testing of a Sustained Vortex-Flow Configuration for Hybrid Rocket Motors
Wilkinson, R.; Day, R.; Hart, K. (2010)One of the drawbacks of hybrid rocket motors is the limited regression rate of the fuel grain, which impacts on the scalablility of the type. A number of methods of increasing this have been proposed and successfully tested, ... -

Reducing environmental damage to agricultural land using improved culvert design
Day, R.; Singer, G. (1993) -
Scour at culvert outlets as influenced by the turbulent flow structure
Liriano, S.L.; Day, R.; White, W.R. (2002) -
Structure of turbulent flow in scour holes downstream of submerged jets
Liriano, S.L.; Day, R. (Rotterdam :Balkema, 2000)
