urban freight transport and policy changes improving decision makers awareness via an agent specific approach
Transport Policy, 2014Co-Authors: Valerio Gatta, Edoardo MarcucciAbstract:This paper derives policy implications from agent-specific data with respect to the implementation of policy changes in the case of urban freight transport. In particular, the research, based on the case of Rome's Limited Traffic Zone, discusses alternative policy scenarios. After describing Attribute Definition and selection, questionnaire administration, data collection and treatment, willingness to pay estimates are calculated.

urban freight transport policy changes improving decision makers awareness via an agent specific approach
2014Co-Authors: Valerio Gatta, Edoardo MarcucciAbstract:This paper derives policy implications concerning a specifically developed questionnaire administration procedure aimed at eliciting agent-s pecific preferences for alternative policy variables with respect to the implementation of pol icy changes in the case of urban freight transport. In particular the research, based on the case of Rome’s Limited Traffic Zone, discusses alternative policy implementations whose impact can be tested ex-ante given the elicitation method adopted. After describing Attribute Definition and selection, questionnaire administration, data collection and treatment, will ingness to pay estimates are calculated. The paper tests, from a policy-maker’s perspective, the implications deriving from the presence of inter-agent heterogeneity and the specific composition of an improving and equally impacting policy on all agent-types’ utility. The paper shows how an agent-specific approach might increase decision makers’ awareness and help them taking better decisions.

usage of micro ct technique reverse engineering software and cad software in the reconstruction of 3d fea model of the tooth structure after root canal therapy
Chinese Journal of Conservative Dentistry, 2010Co-Authors: Yin XiaoAbstract:AIM:To construct the post-root canal therapy(RCT) 3D FEA model of the human mandibular first molar by Micro-CT,reverse engineering software and CAD software.METHODS:Intact human mandibular first molar was scanned by micro-CT.The scanned images were imported to the Mimics 10.01 software and the 3D model was prefabricated.Then,the preliminary 3D model was imported to the Geomagic 10 software and the NURBS toroidal was made after adjustment.According to the morphological parameters of the root canal instruments,the root canal model was made by Pro/Engineer Wildfire 4.0 software.Finally,in the Workbench of pre-processing software of AN-SYS,by Boolean operation and slice,and to Attribute Definition and meshing,the whole model was created.RE-SULTS:The post-RCT 3D FEA model of the human mandibular first molar was constructed successfully.It measureds 0.35mm in tip diameter and 0.02 in root taper.CONCLUSION:The combination of Micro-CT technique,the reverse engineering software and CAD software is an effective way for the reconstruction of 3D FEA model of the tooth structure imitating root canal therapy.

assessing systematic sources of variation in public transport elasticities some comparative warnings
Transportation Research Part A-policy and Practice, 2008Co-Authors: David A HensherAbstract:There is an extensive and continually growing body of empirical evidence on the sensitivity of potential and actual users of public transport to fare and service levels. The sources of the evidence are disparate in terms of methods, data collection strategy, data paradigms, trip purpose, location, time period, and Attribute Definition. In this paper, we draw on a data set we have been compiling since 2003 that contains over 1100 elasticity items associated with prices and services of public transport, and car modes. The focus herein is on direct elasticities associated with public transport choice and demand, and the systematic sources of influence on the variations in the mean estimates for fares, in-vehicle time, and headway obtained from 319 studies. The major influences on variations in mean estimates of public transport elasticities are the time of day (peak, all day vs. off-peak), the data paradigm (especially combined SP/RP vs. revealed preference (RP)), whether an average fare or class of tickets is included, the unit of analysis (trips vs. vkm), specific trip purposes, country, and specific-mode (i.e., bus and train) in contrast to the generic class of public transport.

implementing description logic rules for snomed ct Attributes through a table driven approach
Journal of the American Medical Informatics Association, 2010Co-Authors: Prakash M Nadkarni, Luis A MarencoAbstract:Maintaining a large controlled biomedical vocabulary requires ensuring the content's internal consistency. This is done through rules, specified by the vocabulary's curators, which denote how the vocabulary's concepts should be defined. When individual organizations deploy such vocabularies, local concepts are typically added and linked to concepts in the main vocabulary: the process of maintaining and linking local content should follow the same rules. The operation of content-maintenance software can be facilitated by maintaining such rules in computable form. In this paper, we demonstrate how to implement computable rules for Attribute usage in SNOMED CT using a table-driven approach where a given rule is expressed as one or more rows in a table and is consulted by generic code. This approach, which is tailored to database implementations, is computationally efficient and allows new Attribute-Definition rules to be created as data while needing minimal or no code modification.
