“…The aim of transport infrastructure development should be a sustainable transport system that meets the needs of the economy. Some proposals for a sustainable European transport system are published in [39]. The assessment of the effects of transport infrastructure on road freight transport performance also needs to include the provision of transport infrastructure with car parks and appropriate equipment for drivers' rest in accordance with social rules, which are still being tightened up [40].…”

Transport is key for our economy and society, as good transport infrastructure helps to improve the mobility of citizens and the flow of goods. The European Union intends to maintain support for the development of transport infrastructure in the individual Member States. The aim of this study was to use correlation analysis to compare selected parameters of the road and railway infrastructure of Japan and selected EU countries. The significance of the correlations between various parameters characterizing the transport infrastructure of Japan and selected EU countries was tested. Correlation analysis is not typical in transport-oriented research. Several studies have employed such analysis; however, the majority of them have focused on passenger transport and correlations concerning the behavior of the customers of this mode of transport. The aim of this study was to answer the following research question: is there any correlation between transport performance and infrastructure or investment in infrastructure in relation to the mentioned countries, and, if so, is there a connection between the selected countries where this correlation occurs? Greater investment can also be expected in the construction of high-speed railways, given the decisions of some EU Member States not to resume national air transport where there is good railway infrastructure, even after the end of the COVID-19 pandemic.

Evolution and Forecasting of the Renewable Energy Consumption in the Frame of Sustainable Development: EU vs. Romania

et al. 2021

This article is part of the concerns generated by the need to increase the consumption of renewable energy, so that in the European Union (EU) countries, its share in the final energy consumption, to reach 32% by 2030, increases. In the context in which, in the specialized literature, the analysis of renewable energy consumption by activity sectors is approached very little, such an analysis has high utility. The variables of interest are the share of renewable energy in the final energy consumption, and the share of renewable energy sources in the final energy consumption in transport, electricity, and heating and cooling. The study performs a comparative analysis of the evolution of these indicators for the period 2004–2019 for Romania and the EU, an empirical estimate of the evolution of indicators using time regression and autoregressive models, a forecast of the share of renewable energy consumption in the final energy consumption and by the main sectors (transport, electricity, and heating and cooling) for the 2030 horizon, providing appropriate scenarios for achieving the EU established goals, as well as an analysis of the interdependence between the indicators. Through the results obtained, the paper can contribute to improving the framework for the sustainable development of energy consumption.

“…Polymer electrolyte membrane fuel cells (PEMFCs) are among the most efficient electrical generators due to several properties like high energy density, performance and high robustness [3], which leads to multiple applications such as portable power generation, cars, aircrafts and space shuttles [4][5][6][7][8][9][10]. In such application, DC-DC high step-up power converters are usually desired not only for boosting the PEMFC low voltage, but also to provide regulated output voltage for end use.…”

An Efficient and Robust Current Control for Polymer Electrolyte Membrane Fuel Cell Power System

et al. 2021

Taking into account the restricted ability of polymer electrolyte membrane fuel cell (PEMFC) to generate energy, it is compulsory to present techniques, in which an efficient operating power can be achieved. In many applications, the PEMFC is usually coupled with a high step-up DC-DC power converter which not only provides efficient power conversion, but also offers highly regulated output voltage. Due to the no-linearity of the PEMFC power systems, the application of conventional linear controllers such as proportional-integral (PI) did not succeed to drive the system to operate precisely in an adequate power point. Therefore, this paper proposes a robust non-linear integral fast terminal sliding mode control (IFTSMC) aiming to improve the power quality generated by the PEMFC; besides, a digital filter is designed and implemented to smooth the signals from the chattering effect of the IFTSMC. The stability proof of the IFTSMC is demonstrated via Lyapunov analysis. The proposed control scheme is designed for an experimental closed-loop system which consisted of a Heliocentric hy-Expert™ FC-50W, MicroLabBox dSPACE DS1202, step-up DC-DC power converter and programmable DC power supplies. Comparative results with the PI controller indicate that a reduction of 96% in the response time could be achieved using the suggested algorithm; where, up to more than 91% of the chattering phenomenon could be eliminated via the application of the digital filter.
