Design of optimized tread profile for high-speed EMUs
To address two significant issues in high-speed electric multiple units (EMU), i.e. degraded vehicle dynamic performance under existing wheel-rail interactions and increased wheel tread wear at elevated operating speeds, this paper proposes an optimized tread profile design that balances wheel-rail interactions, dynamic performance, and wear resistance.

Test Study on Carbody Abnormal Vibration of High-speed EMUs
, 2014 Carbody abnormal vibration analysis of a high-speed EMUs was researched, mainly containing the wheel tread measurements,carbody vibration on-line test, turn around running and vibration compared before and after repairing profile. The results showed that the change of wheel/rail wear matching in the partial line induced equivalent conicity increasing ...

Metroeconomica, EarlyView.ABSTRACT This paper examines the complex relationship between government debt and income distribution within a post‐Keynesian framework. Extending the model of You and Dutt (1996), we model both capitalists and workers as holders of government bonds, enabling a more nuanced analysis of income distribution dynamics.

European Identity and the Euro in Kosovo
Nations and Nationalism, EarlyView.ABSTRACT How can nationalist leaders stand for political independence and monetary sovereignty while embracing the use of a supra‐national currency? At first sight, unilateral euroisation—the de facto adoption of the euro instead of a national currency—seems inconsistent with the goals of nationalism and independence.

An Overview of the NASA Advanced Composites Consortium High Energy Dynamic Impact Phase II Technical Path [PDF]
Advanced composite structures are increasingly becoming the norm for use in military and commercial aircraft. Many of these structures are in places that are prone to high energy dynamic impact (HEDI) such as a wing or fuselage structures subjected to ...

Panel Sequential Group Estimation of Interactive Effects Models
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT This paper proposes a novel procedure to identify latent groups in the slopes of panel data models with interactive effects. The method is straightforward to apply and relies only on closed‐form estimators when evaluating the objective function.

Design of LED Information Display for High Speed EMUs
, 2010 This paper introduced the project development of localization LED information display, which was part for 200 km/h, 300 km/h EMUs. Emphasis had been put on the scheme design for TPX31 passenger information display. The problems happed during production process and its solutions had also been analyzed.

Regulation &Governance, EarlyView.ABSTRACT During and following the Covid‐19 pandemic, the European Union (EU) is taking first steps toward a European Health Union (EHU). There is no set definition of what an EHU is, but in this paper, we explore the popular support for different designs of an EHU, including a pillar in which healthcare policy competences are shared between the EU and ...
