Item Open Access 1d compression creep behaviour of kaolinite and bentonite clay(2011) Varatharajan, Sivarajan; Wong, Ronald C. K.Creep mechanisms and factors influencing the creep in clay soils are not yet well understood due to the complex structure of clay matrix. An experimental program was conducted to investigate the parameters affecting the creep behaviour. One-dimensional single stage, stepwise and overloaded-unloaded compression creep tests were conducted using standard oedometer apparatus on kaolinite and bentonite clay samples. Single and radial drainage conditions with different pore fluids were considered. Required creep stress levels were achieved using instantaneous loading increments. Effects of stress level, stress history, pore fluid chemistry, fabric structure, drainage condition and mineral compositions of clay on creep behaviour were studied based on the experimental results. Drainage condition exhibited insignificant influence on creep. Creep mechanisms were explained as a combined effect of sliding of clay particles at their contacts and deformation of particle itself. Compression of micro pores during the creep is negligible. Developed model successfully describes the creep behaviour interims of viscosity.Item Open Access A Comparison of irrigation upstream automatic controllers(1991) Schaalje, Michael A.; Manz, David H.Item Open Access A comparison of the sample survey and open house methods of public consultation for transportation issues in the City of Edmonton(2004) Mackay, Malcolm; Hunt, John DouglasItem Open Access A computer tool for managing logistics in construction industry(2011) Almohsen, Abdulmohsen; Ruwanpura, JanakaItem Open Access A computer-aided mixture proportioning system for durable concrete(2002) Nazir, Mohamed Nizar Mohamed; Day, Robert L.Item Open Access A Coupling connection for precast column bases(1986) Tsoi, Helena M., 1948-; Loov, Robert E.Item Open Access A Decision Support System for Risk Management of Contaminated Sites(2011) Kluck, Cheryl Lee; Achari, GopalItem Open Access A Discrete/continuous model for the joint choice of node and shipment size in freight transportation(1991) Abdelwahab, Walid M.; Sargious, Michel A.Item Open Access A framework for joint implementation: the Rusagas carbon offset project(2002) Venugopal, Srikanth; Hettiaratchi, J.

The model was validated using results and data published in literature and has been used to study how the efficiency of a gas collection system may be impacted by a number of factors including vacuum pressure, well screen length, intermediate and final covers' thickness and permeability, number of gas collection wells and direction of well placement. The results suggest that a higher gas collection rate can be achieved by using a vertically placed well with a stronger vacuum pressure, a longer well screen, and a thicker and less permeable final cover, while undesirable air intrusion may be minimized by installing a larger number of wells.Item Open Access A Guide for implementation and utilization of pavement management systems(1988) Enslen, Peter M.; Sargious, Michel A.Item Open Access A model for real-time monitoring of pavements for public-private partnership(2008) Lakkavalli, VenkataKrishna; Cowe Falls, LynneItem Open Access A model to predict the undrained response of loose gassy sand(2004) Mathiroban, Shanmugalingam; Grozic, Jocelyn L.H.Item Open Access A molecular tool for the detection of waterborne pathogens(1998) Mrklas, Ole; Chu, AngusItem Open Access A multiple-isotope approach to tracing natural gas processing emissions(2005) Bradley, Carole Erin; Chu, AngusItem Open Access A nested logit model of the household choice of home location, workplace locations and commuting modes in Calgary(1994) Abraham, John E.; Hunt, John DouglasItem Open Access A new model, algorithm and computer tool to optimize overlapping of design activities in construction projects(2011) Dehghan, Reza; Ruwanpura, JanakaAn effective and well known technique for earlier completion of construction projects is to overlap the project activities or phases that normally would be performed in sequence. Overlapping is inherently risky because it increases project uncertainties, rework, complexity, and eventually cost. For a typical construction project, a huge number of overlapping strategies exist which all can result in the same timesaving. However, the cost of these strategies varies significantly depending on the total rework and complexity they generate. A favourable overlapping strategy is one that generates the required timesaving at the minimum cost. To find the favourable overlapping strategy, the question "Which activities have to be overlapped and to which extent to reduce the project duration at the minimum cost?" should be answered. This research aimed at answering the question through generating an overlapping optimization algorithm. The scope of the research covers any type of activities in the design phase. A combinatory research methodology, a combination of qualitative and analytical approaches, was customized to conduct the research. Interviews and focus groups were the research instruments in the qualitative part. The analytical part included developing the overlapping optimization algorithm and its associated computer tool. The research generated three deliverables: An overlapping model, an overlapping optimization algorithm, and an overlapping optimization computer tool. The overlapping model explains the overlapping mechanism. The computer tool works based on the overlapping optimization algorithm and assesses various overlapping strategies and identifies the least expensive strategies. The tool is actually a cost evaluation module linked to a commercial project scheduling software (MS Project). This computer tool is so user-friendly that any scheduler or cost controller can easily run it and modify the schedule accordingly. The computer tool is unique and new as so far no similar tools exist in industry or academia. It can optimize overlaps in large and complex project schedules in fairly short processing times. It is able to handle multi-path networks and all types of activity dependencies. The tool takes all activities, critical and non-critical, into account and follows the critical path if the critical path changes or new critical paths emerge. The tool can also take resource limitations and schedule constraints into account.Item Open Access A new non-metallic anchorage system for post-tensioning applications using CFRP tendons(1999) Taha, Mahmoud Reda; Shrive, Nigel G.Item Open Access A parametric study of shear provisions for stiffened plate girders(2000) Parthasarathi, N.; Loov, Robert E.
