The Macro Vulnerabilities to the Clean Energy Transition: An Empirical Assessment

open access: yesSustainable Development, EarlyView.
ABSTRACT The macro environment is one of the analytical levels of the multilevel transition perspective that has the potential to shape the clean energy transition. Following the Political, Economic, Social and Technological (PEST) framework, the present study analyzes the paths by which these four macro dimensions jointly shape wind, solar, and ...

Efficient Harvesting of Irregular and Low‐Frequency Mechanical Energy via Hybridized Electromagnetic‐Triboelectric Systems

open access: yesSmall, EarlyView.
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Do Product Market Reforms Work? Assessing Regulatory Changes Impacting Competition

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT We create a new dataset that characterizes studies of product market reforms implemented from 1932 to 2011. We examine the size and origins of differences in estimated impacts based on an OECD classification scheme for potentially competitive restrictions of regulation. The median impact from switching to a pro‐competitive environment is a 19%

Experimental tests of vehicle body accelerations at selected road and rail crossings

open access: yesMATEC Web of Conferences, 2019
Vehicles moving across the railway are exposed to the dynamic reaction of unevenness of surface on those level crossing. This significantly influences on the increase of the acceleration as well as forces values transferred to the body of the car.

Mobile warning system for railway level crossings [PDF]

open access: yes, 2009
The aim of the work was to implement and test an in-vehicle warning system for railway level crossings. A prototype was built and tested on HankoKarjaa railway line in southern Finland. The prototype was based on GPS, GPRS and laptop computers.

Increasing the Reuse Potential of High‐Strength Steels by Extending the Fatigue Life through Surface Treatments

open access: yessteel research international, EarlyView.
Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.

Investigation of the Reoxidation and Material Behavior of Directly Reduced Pellets and Fines Under Simulated Rail Transport Conditions

open access: yessteel research international, EarlyView.
The study investigates the reoxidation behavior of DRI pellets (Midrex and H2‐reduced) under realistic conditions, considering the test parameters of temperature, humidity, storage duration, particle size (including fine fraction), and container geometry. The samples are analyzed based on mass changes.

Driver behaviour and decision making at railway level crossings : An exploratory on-road case study [PDF]

open access: yes, 2010
Crashes at rail level crossings represent a significant problem, both in Australia and worldwide. Advances in driving assessment methods, such as the provision of on-road instrumented test vehicles, now provide researchers with the opportunity to further
