operational variables of a mineral processing circuit are subjected to different variations. steady-statesimulation of processes provides an estimate of their ideal stable performance whereas their dynamicsimulation predicts the effects of the variations on the processes or their subsequent processes. in thispaper, a dynamic simulator containing some of the major equipment of mineral processing...

The paper studies the short run and long run effects of a production subsidy to the tourism sector of a small open economy, which can also be thought as a region within a country. We introduce a two-sector dynamic general equilibrium model where the tourism sector is considered to be labor-intensive and produces traded services. The other sector is capital-intensive and produces a nontraded goo...

cellular manufacturing system is one of the most important applications of group technology. design of this system involves many structural and operational issues, in which the cell formation and production planning are two important steps. in this paper, a new mathematical model is proposed for integration of cell formation and production planning problems with the aim of minimizing the overal...

Saccharomyces cerevisiae (baker’s yeast) can exhibit sustained oscillations during the operation in a continuous bioreactor that adversely affects its stability and productivity. Because of heterogeneous nature of cell populations, the cell population balance equation (PBE) can be used to capture the dynamic behavior of such cultures. In this work, an unstructured-segregated model is used f...

This paper shows that existing estimates of labor supply elasticities place a tight upper bound on risk aversion in an expected utility model. I derive a formula that relates the coefficient of relative risk aversion (γ) to the ratio of the income elasticity of labor supply to the wage elasticity, holding fixed the degree of complementarity between consumption and leisure. The degree of complem...

Subjective Discount Rates, Intergenerational Transfers and the Return to Schooling Using a dynamic programming model of schooling decisions, we investigate the relationship between subjective discount rates and the labor market ability (the discount rate bias) on a panel taken from the National Longitudinal Survey of Youth (NLSY). Given household human capital and Armed Forces Qualification tes...

Asian development in the 1970's is likely to take place under conditions quite different from those typical of the past two decades. These changing conditions will have an important influence on the research focus relating to growth and development. This paper examines two such changes. First, the population explosion of the 1940's and 1950's will be transformed into a labor force explosion in ...
