This paper describes an analysis of the reduction of the heat flux coming into a room through a roof with an open water pond. A periodic analysis of the system, based on the linearisation of Dunkle's6 expressions for convective, radiative and evaporative losses, is presented. Numerical...

Hilly terrains with steep slopes and poor vegetative cover are prone to soil erosion. Crop productivity from such lands can be increased by adding correct amounts of soil conditioners such as polyacrylamide (PAM) and gypsum (G) to reduce soil erosion and to improve settling of suspended...

A fractional normal inverse Gaussian (FNIG) process is a fractional Brownian motion subordinated to an inverse Gaussian process. This paper shows how the FNIG process emerges naturally as the limit of a random walk with correlated jumps separated by i.i.d. waiting times. Similarly, we show that...

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....

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...

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...

An existence of good governance situation ensures the progress of economic sectors. The recent literature has mentioned the role of country governance in multiple business operations. However, the effect of country governance on trade credit is not yet explored in the literature. Thus, the...
