The present article considers Bayesian unit root test for autoregressive model involving structural break in variance. The posterior odds ratio for testing of unit root hypothesis against the alternative of break in variance has been derived under appropriate prior assumptions for the...

The present paper considers the testing of unit root hypothesis for an autoregressive model with polynomial trend under Bayesian framework. Under the unit root hypothesis the trend component does not vanish completely and its degree reduces by one. The posterior odds ratio for the unit root...

Western Canada is endowed with considerable reserves of deep un-mineable coal, which can be converted to syngas by means of a gasification process called underground coal gasification (UCG). The syngas can be transformed into hydrogen (H2) through commercially available technologies employed in...

A model-FUNNEL-GHG-OS (FUNdamental ENgineering PrinciplEs- based ModeL for Estimation of GreenHouse Gases in the Oil Sands) based on fundamental engineering principles was developed to estimate the specific energy consumption and GHGs (greenhouse gas emissions) for upgrading bitumen to produce...

The formulation of the static user equilibrium traffic assignment problem (UETAP) under some simplifying assumptions has a unique solution in terms of link flows but not in terms of path flows. Large variations are possible in the path flows obtained using different UETAP solution algorithms....

A model – FUNNEL-GHG-OS (FUNdamental ENgineering PrinciplEs-based ModeL for Estimation of GreenHouse Gases in the Oil Sands) was developed to estimate project-specific energy consumption and greenhouse gas emissions (GHGs) in major recovery and extraction processes in the oil sands, namely...

The present study investigates the status of the urban environment in Ranchi, a rapidly growing city in the eastern part of India. The various environmental indicators viz., ambient air quality, aerosol concentration, ambient noise level and urban green space were analysed in a spatio-temporal...

Biomass can be used for the production of fuels, and chemicals with reduced life cycle (greenhouse gas) emissions. Currently, these fuels and chemicals are produced mainly from natural gas and other fossil fuels. In Western Canada, forest residue biomass is gasified for the production of syngas...

The environmental performance of production and distribution of densified form of lignocellulosic biomass (i.e., agri-residue based pellets) in Western Canada in terms of energy and greenhouse gas (GHG) emission was assessed. The results show that energy usage and resulted emissions are highest...
