In this paper we study the impact on productivity of specific operating practices currently used by demand responsive transit (DRT) providers. We investigate the effect of using a zoning vs. a no-zoning strategy and time-window settings on performance measures such as total trip miles, deadhead miles and fleet size. It is difficult to establish closed form expressions to assess the impact on th...

1. INTRODUCTION The present study advocates a strategy aimed at implementing the principles of sustainable development through operational tools to be used in programs for environmental conservation. To be more precise, I lay out a proposal of participatory zoning that is innovative in two main respects: i) it is based on an assessment of the territorial setup and the social values of the peopl...

This paper concerns the problem of matching incompatible zonal geographies, for example in the context of comparing census outputs over time. The automated zoning procedure (AZP) proposed by Openshaw (1977) is reviewed, and a population stress statistic proposed which may be used in an AZP algorithm in order to maximise the match between two zonal geographies. An implementation of this approach...

In this paper we investigate whether unsupervised models can be used to induce conventional aspects of rhetorical language in scientific writing. We rely on the intuition that the rhetorical language used in a document is general in nature and independent of the document’s topic. We describe a Bayesian latent-variable model that implements this intuition. In two empirical evaluations based on t...

We explore the potential effects of magmatic assimilation on mineral growth and mineral zoning in an alkali olivine basaltic magma using both equilibrium thermodynamics and kinetics. The equilibrium-model calculations simulate fractional crystallization alone (closed system) and coupled assimilation fractional crystallization (AFC) (open system); the models predict the assemblages ofmagmatig mi...

Transport modelling and in particular transport assignment is a wellknown bottleneck in computation cost and time for urban system models. The use of Transport Analysis Zones (TAZ) implies a trade-off between computation time and accuracy: practical computational constraints can lead to concessions to zone size with severe repercussions for the quality of the transport representation in urban m...

In the last decade, dozens of local governments have enacted zoning ordinances designed to limit the concentration of payday lenders and other alternative financial services providers (AFSPs), such as check-cashing businesses and auto title loan shops, in their communities. The main impetus for these ordinances is to shield economically vulnerable residents from the industry's lending practices...

This paper concerns the problem of matching incompatible zonal geographies, for example in the context of comparing census outputs over time. The automated zoning procedure (AZP) proposed by Openshaw (1977) is reviewed and extended to permit its application to the intersection of two zonal systems. A population stress statistic is proposed which may be used in the extended AZP algorithm in orde...

We present an automated approach to classify sentences of scholarly work with respect to their rhetorical function. While previous work that achieves this task of argumentative zoning requires richly annotated input, our approach is robust to noise and can process raw text. Even in cases where the input has noise (as is obtained from optical character recognition or text extraction from PDF fil...

Abstract Phosphorus X‐ray maps of olivine phenocrysts in many type II (FeO‐rich) porphyritic chondrules LL3.00 Semarkona and CO3.05 Y 81020 reveal multiple sets thin dark/bright (P‐poor/P‐rich) layers that resemble oscillatory zoning. Such discrete are generally not evident BSE images or Fe, Cr, Ca, Al, Mg, Mn because rapid diffusion these cations at high temperatures smoothed out their initial...
