OBJECTIVES We develop and test a conceptual model of factors influencing women's ideal family size (IFS) in a natural fertility population, the Tsimane of Bolivia. The model posits affects of socioecology, reproductive history, maternal condition, and men's IFS. We test three hypotheses for why women may exceed their IFS despite experiencing socioeconomic development: (H(1) ) limited autonomy; ...

Batch reverse osmosis (RO) is a promising approach to high-recovery desalination. It has low energy consumption, but system size increases sharply with recovery because of the need for large work exchange vessel. In this study, we propose compact hybrid batch/semi-batch (HBSRO) incorporating aspects each approach. HBSRO works in three phases, i.e. semi-batch pressurisation phase, batch and fina...

This study tests the hypothesis that, in Nepal, measures of ideal family size mask an underlying preference for sons, making some people willing to have families larger than their ideal. Existing evidence suggests that men are likely to have stronger preferences for sons than are women. This research uses empirical evidence to examine the hypothesis that husbands are more willing than their wiv...

Flexible manufacturing system (FMS) readily addresses the dynamic needs of the customers in terms of variety and quality. At present, there is a need to produce a wide range of quality products in limited time span. On-time delivery of customers’ orders is critical in make-to-order (MTO) manufacturing systems. The completion time of the orders depends on several factors including arrival rate, ...

In this research the growth of an initial population is studied for seeded batch crystallization of ammonium sulphate in water. The system is analysed in a comparison with so-called ideal growth behaviour. Ideal growth is a situation where the number of crystals remains constant during the batch. Deviation from ideal growth can be caused by partial dissolution of the seeds or by nucleation. The...

Batch distillation is an important separation process for small-scale production especially in pharmaceutical, specialty chemical and biochemical industries. Although batch distillation units require lower capital cost than continuous units, the unsteady state nature of the process, results in higher operating costs. Optimal control in batch distillation is a mode of operation which allows us t...

Determining the appropriate batch size for mini-batch gradient descent is always time consuming as it often relies on grid search. This paper considers a resizable mini-batch gradient descent (RMGD) algorithm based on a multi-armed bandit for achieving best performance in grid search by selecting an appropriate batch size at each epoch with a probability defined as a function of its previous su...

Current methods used to calculate the required size of hospitals are underestimating the true capacity needed for operational efficiency. Trends in occupied bed-days (rather than admissions and length of stay) give better estimates of future bed requirements. Hospital occupancy rates depend on volatility in demand, not efficiency. Larger bed pools and hospitals can operate at higher average occ...
