Impact of wheel shape on the vertical damage of cast crossing panels in turnouts [PDF]
, 2015 Impact forces generated in the load transfer area of railway crossing panels lead to a range of degradation modes from wear and fatigue of the contacting materials, fatigue of supporting components to ballast/subgrade deterioration.

Integrated routing of heavy electrical and diesel trucks in forest transports
International Transactions in Operational Research, EarlyView.Abstract Fossil‐free forestry transports are important to reach climate goals. In Sweden, road transports account for around 50% of the industry's CO2 emissions and almost 20% of the road freight volumes. Previous studies have shown that electrification is a cost‐effective way for carbon abatement, while at the same time the requirements for ...

Symmetric Brownian motor [PDF]
, 2005 In this paper we present a model of a symmetric Brownian motor (SBM) which changes the sign of its velocity when the temperature gradient is inverted. The velocity, external work and efficiency are studied as a function of the temperatures of the baths ...

Scheduling optimization of optical lens polishing
International Transactions in Operational Research, EarlyView.Abstract Optical systems have achieved notable progress in focusing and imaging technologies; however, manual grinding remains indispensable, resulting in elevated costs, extended timelines, and inefficiencies. These difficulties are compounded by operational constraints, uneven machine utilization, and risks of order delays and escalating expenses ...

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.

Issued as a Documentation Report on an Investigation of Field-Made Joints in Prestressed Reinforced Concrete Highway Girder Bridges, Project IHR-303, Phase 2 [PDF]
, 1977 A prototype bridge girder was designed, built, and tested. The 250 ft long two-span girder was made of 3 precast segments about 88, 74, and 88 ft in length. The segments were supported on 3 final and 2 temporary supports.

Journal of Field Robotics, Volume 43, Issue 2, Page 847-878, March 2026.ABSTRACT This paper presents the development and validation of a scalable platooning system based on the predecessor‐following (PF) topology, designed for low‐cost follower platforms. It integrates key technologies such as localization, path planning, profile generation, and low‐level control to create a practical solution.
