This paper aims to introduce thermal energy storage technology into a solar-powered dual-packed bed desalination system. By prehesdating and reserving seawater during the daytime utilizing it at night, integrated system with innovative configuration can achieve freshwater electricity combined generation particularly realize continuous operations for water production. The detailed mathematical m...

In the present paper we review and extend two stochastic models for loss resenting and study their impact on extensions of the additive method and of the chain-ladder method. The first of these models is a particular linear model while the second one is a sequential model which is composed of a finite number of conditional linear models. These models lead to multivariate extensions of the addit...

Verrall (1996) and England & Verrall (2001) first considered the use of smoothing methods in the context of claims reserving. They applied two smoothing procedures in a likelihood-based way, namely the locally weighted regression smoother (‘loess’) and the cubic smoothing spline smoother. Using the statistical methodology of semiparametric regression and its connection with mixed models (see e....

To formulate a single-leg seat inventory control problem in an airline ticket sales system, the concept and techniques of revenue management are applied in this research. In this model, it is assumed the cabin capacity is stochastic and hence its exact size cannot be forecasted in advance, at the time of planning. There are two groups of early-reserving and late-purchasing customers demanding t...

Since in large parts of the world it is getting difficult to meet growing water demands by mobilising more water, the discourse has turned its focus to demand management, governance and the necessary concern for aquatic ecosystems by reserving an “environmental flow” in the river. The latter calls for attention to river depletion which may be expected in response to changes in consumptive water...
