Several factors, including economical, environmental, and social factors, are involved in selection of the best fuel-based vehicles for road transportation. This leads to a multi-criteria selection problem for multi-alternatives. In this study, a multi-criteria assessment model was developed to...

The increased requirement of hydrogen in the refinery is fulfilled by proper distribution of available hydrogen in the refinery, using additional hydrogen production system and by importing. Amongst these options first one is cost effective as no addition source is required. Thus, the present...

Optimal use of scarce water resources is the prime objective for water resources development projects in the developing country like India. Optimal releases have been generally expressed as a function of reservoir state variables and hydrologic inputs by a relationship which ultimately allows...

An intriguing phenomenon of reversible flocculation of charge-stabilised colloids in liquid mixtures is described. Some recent results concerning the shape of the flocculation surface, especially near special critical points (e.g. a double critical point, DCP), are also discussed. The findings...

Laguna Lake is the largest inland water resource in the Philippines and an important source of fisheries in the area. The Pagsanjan-Lumban catchment is the main freshwater input of the lake but contaminants resulting from agricultural activities within the catchment may impact fisheries....

The light scattering measurements that yield the osmotic susceptibility (χT) in a ternary liquid mixture of 3-methylpyridine+water+sodiumbromide are presented. The measurements have been performed in the one-phase region near the lower consolute points TL's of samples with different...

Measurements are reported of the intensity and the angular dissymmetry of light scattered from ‘quasi-binary’ and binary mixtures of ethane and heavier hydrocarbons, that have varying widths of the three-phase region (ΔT). The critical exponents γ and v are estimated by approaching the...

We consider time-changed Poisson processes, and derive the governing difference–differential equations (DDEs) for these processes. In particular, we consider the time-changed Poisson processes where the time-change is inverse Gaussian, or its hitting time process, and discuss the governing...

In this paper we define semi-stable probability measures (laws) on a real separable Hilbert space and are identified as limit laws. We characterize them in terms of their Lévy-Khinchine measure and the exponent 0 p = 2. Finally we prove that every semi-stable probability measure of exponent p...
