This review paper assesses oil supply modeling techniques and critically evaluates their usefulness in projecting future oil production. It reviews models that project future rates of oil production, but does not address estimation of oil resources. The following types of models are reviewed:...

Purpose – The purpose of this paper is to examine how utilization of non‐financial manufacturing performance (NFMP) measures impacts the lean manufacturing/financial performance relationship. Design/methodology/approach – A structural equation model (SEM) is estimated using data provided...

A domestic solar dryer with transparent external surfaces was designed, built and tested. Thin-layer drying models that describe the drying phenomena in a unified way, regardless of the controlling mechanism; have been used to estimate the drying period for several products. Temperature of the...

The present study provides a descriptive mathematical model for energy and exergy analysis for a cocurrent gas spray cooling system. Conservation laws of mass, energy and momentum are used to predict the variation of temperature and enthalpy of gas and liquid streams along the tower length. The...

Purpose – Extensive literature on business process management suggests that organizations could enhance their overall performance by adopting a process view of business. However, there is a lack of empirical research in this field. The purpose of this paper is to investigate the understanding...

The paper presents Tozer's study of the effects of the mechanization of productive activities on employment as an effort to devise a mathematical model, as an analytical method that would be more general and robust than Ricardo's numerical examples. The contradictory nature of this achievement...

A modification to the conventional Gompertz equation (named modified Gompertz equation) is introduced to describe the solid tumor growth perturbed with direct electric current. Simulations of this equation are made. Quantitative fitting criteria as goodness-of-fit, handling missing data and...

Little is known about how human cancers grow because direct observations are impractical. Cancers are clonal populations and the billions of cancer cells present in a visible tumor are progeny of a single transformed cell. Therefore, human cancers can be represented by somatic cell ancestral...
