Calibration of the modified Bartlett-Lewis model using global optimization techniques and alternative objective functions

The calibration of stochastic point process rainfall models, such as of the Bartlett-Lewis type, suffers from the presence of multiple local minima which local search algorithms usually fail to avoid. To meet this shortcoming, four relatively new global optimization methods are presented and tested for their ability to calibrate the Modified Bartlett-Lewis Model. The list of tested methods consists of: the Downhill Simplex Method, Simplex-Simulated Annealing, Particle Swarm Optimization and Shuffled Complex Evolution. The parameters of these algorithms are first optimized to ensure optimal performance, after which they are used for calibration of the Modified Bartlett-Lewis model. Furthermore, this paper addresses the choice of weights in the objective function. Three alternative weighing methods are compared to determine whether or not simulation results (obtained after calibration with the best optimization method) are influenced by the choice of weights

Leven, wonen en werken in onzekere tijden. Patronen van bevolking en arbeid in België in de 'lange negentiende eeuw'

Lifestyles, living conditions and employment in uncertain times. Population and employment patterns in Belgium during the 'long, drawn-out nineteenth century', Eric VanhauteIn recent decades, historic-demographic research has asked new questions, used new sources and experimented with new methods. Yet these innovative trends which have produced a wealth of findings, have failed to revive the debate about broad, overarching patterns and models, which is still dominated by all-encompassing modernization concepts such as the 'demographic transition'. This article argues for a renewed, unbiased dialogue between micro and macro approaches and formulates some ideas about bridging the gap between the rich but splintered domain of demographic micro research and historicising models of social transitions. A survey is presented on the accumulated knowledge about important transitions in demographic trends witnessedin 19th century Belgium: Population growth, birth rates, death rates, nuptuals and fertility, conditions in which people lived together and family formations, as well as housing and employment. These processes are subsequently interpreted within the context of the structural transition to an 'extensive' 19th century and an 'intensive' 20th century social model, respectively
