Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs
Journal of Regional Science, Volume 65, Issue 2, Page 471-496, March 2025.ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.

Automated extraction of leaf mass per area from digitized herbarium specimens
New Phytologist, EarlyView.Summary The digitization of vast herbarium collections has made millions of plant specimen images freely available online, which can now be used to generate phenotypic datasets of unprecedented scope. Here, we assess the potential of computer vision tools to automate the extraction of predicted leaf mass per area (LMApred) from digitized herbarium ...

Subnational Border Reforms and Economic Activity in Africa
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT Using GIS methods, we identify territories in Africa affected by subnational border reforms between 1992 and 2013. Descriptive statistics reveal that these territories differed from other African regions across several key dimensions. For example, these territories were more populous and exhibited greater ethnic diversity.

, 2013 The management of massive amounts of geodata collected by sensor networks creates several challenges, including the real-time application of summarization techniques, which should allow the storage of this unbounded volume of georeferenced and timestamped data in a server with a limited memory for any future query. SUMATRA is a summarization technique,

Transactions in GIS, Volume 30, Issue 2, April 2026.ABSTRACT The proliferation of AI‐generated building footprints in OpenStreetMap (OSM) has transformed crowdsourced mapping, yet the geometric characteristics associated with different digitization methods remain poorly understood. This study presents a comprehensive morphometric analysis of more than 9 million building footprints across 15 ...

International Journal of Engineering Research and Technology, 2020 © International Research Publication House An analysis of the developed system was carried out. As a result of the analysis, the main precedents of the system were determined, a BPMN diagram was built, an alternative solution was analyzed, and the basic requirements for the system were derived.
