Computationally Efficient Ranking of Sampling Locations by Redundancy in Groundwater Monitoring Networks

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract The long‐term and frequent sampling of groundwater monitoring networks is common practice for monitoring the concentrations of constituents of potential concern (CoPC) over space and time. Sampling can be a costly and time‐intensive process that also incurs health and safety risks. A redundancy‐based ranking of candidate sampling locations can

Impacts of a global energy crisis on supply chain performance, ripple effects, and viability

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract We simulate impacts of a global energy crisis on supply chains (SCs). First, we articulate the specific features that frame a global energy crisis as a unique type of SC large‐scale systemic shocks characterized by a long‐term disruption existence, disruption propagations (i.e., the ripple effect), a combination of immediate and delayed ...

Experimental Investigation under Unsteady Flow Conditionson Turbocharger Compressors for Automotive Gasoline Engines

open access: yes, 2012
Downsizing and turbocharging is today considered an effective way to get reduced CO2 emissions of automotive gasoline engines. An important aspect to take into account is the turbocharger behaviour under the strong unsteady flow conditions occurring in ...

Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs

open access: yesJournal 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.

The Impact of Autonomous Truck Technology on US Interstate Trade

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT Recent advances in autonomous and semi‐autonomous vehicle technologies promise substantial cost savings for goods shipped by truck. In this study, we quantify the impacts of these transport cost reductions on the US interstate trade using a structural gravity model of domestic trade. Based on projected cost savings from the widespread adoption

The U.S. ethanol industry [PDF]

open access: yes
Ethanol is vital to achieving greater American energy independence. It is today's only viable and available fuel that can be substituted for gasoline. Unlike oil, ethanol is renewable-it will never run out.

Two Nationalisms, One City: Official and Diasporic Framings of the 2019 Hong Kong Protests

open access: yesNations and Nationalism, EarlyView.
ABSTRACT This study analyses the contested collective memories of the 2019 Anti‐Extradition Law Amendment Bill (Anti‐ELAB) movement, investigating how the Hong Kong government and diaspora construct divergent narratives to shape national identity and nationalism.

Study of fuel injection and mixture formation for a gasoline direct injection engine

open access: yes, 2005
Future requirements for lower automotive emissions have lead to the development of new internal combustion (IC) engine technologies. Gasoline Direct Injection (GDI), for example, is one of these promising new IC engine concepts.
