The effect of electrified mobility on the relationship between traffic conditions and energy consumption
Full text linkDecreasing road transport's harmful effects on environment and health and reducing road accidents are major policy priorities. A variety of technologies could drastically improve air quality, reduce energy consumption and CO2 emissions of road vehicles: in this respect, a prominent trend leverages Electric Vehicles (EVs), supported by improved performance and energy efficiency through connectivity and automation. A noteworthy research question in the transition from Internal Combustion Engine Vehicles (ICEVs) to the alternative technologies, is to understand how Intelligent Transport Systems and other traffic-related measures can contribute to the reduction of fuel consumption and greenhouse gas emissions. In fact, a widely acknowledged tenet assumes that congestion removal or mitigation in presence of ICEVs implies also a reduction of transport-related externalities. This paper explores whether this effect still holds for EVs, by performing an analysis of energy consumption over different vehicle trajectories, under both congested and free-flow conditions. Calculations are carried out using two vehicle simulators: the VT-CPEM (Virginia Tech Comprehensive Power-based Energy consumption model) model for EVs and the CO2MPAS (CO2 model for Passenger and commercial vehicle Simulation) vehicle simulator for the ICEVs, for both electric and conventional cases passengers and freight/commercial powertrains have been analysed. Results are presented on real and simulated data related to four powertrain-vehicle combinations, in terms of general trends of energy/fuel consumption versus speed. Interestingly, results show that, differently from ICEVs, the relationship between congestion and energy consumption underlying EVs can change with higher energy consumption connected to an increased average traffic speed

Dei delitti e delle pene nella traduzione di Michail M. Scerbatov
Full text linkAfter more than two centuries, this work presents the Russian version of “Dei delitti e delle pene” by Cesare Beccaria, translated by Prince Michail M. Šcerbatov. The edition, conducted on the autographed manuscript, is presented with the original Italian text. In the introductory study, the author traces the fundamental stages of the diffusion of Beccaria’s work in Russia, focusing in particular on the figure of Michail M. Isaev, scholar and translator of the masterpiece by Beccaria, who was the first to re-propose the modern organisation of the “Fifth” edition. The author gives an account of the version proposed by Šcerbatov, investigating its textual genesis and evaluating some aspects of the language used by the translator - first of all the lexicon used for the rendering of philosophical-political and legal terms
Investigating the behavior of advanced automated systems in vehicle-platoons through empirical observations
No full textAdaptive physics-informed trajectory reconstruction exploiting driver behavior and car dynamics
No full textAs more and more trajectory data become available, their analysis creates unprecedented opportunities for traffic flow investigations. However, observed physical quantities like speed or acceleration are often measured having unrealistic values. Furthermore, observation devices have different hardware and software specifications leading to heterogeneity in noise levels and limiting the efficiency of trajectory reconstruction methods. Typical strategies prune, smooth, or locally modify vehicle trajectories to infer physically plausible quantities. The filtering strength is usually heuristic. Once the physical quantities reach plausible values, additional improvement is impossible without ground truth data. This paper proposes an adaptive physics-informed trajectory reconstruction framework that iteratively detects the optimal filtering magnitude, minimizing local acceleration variance under stable conditions and ensuring compatibility with feasible vehicle acceleration dynamics and common driver behavior characteristics. Assessment is performed using both synthetic and real-world data. Results show a significant reduction in the speed error and invariability of the framework to different data acquisition devices. The last contribution enables the objective comparison between drivers with different sensing equipment

Fairness on ramp metering. Extending ALINEA for equitable access and congestion reduction
No full textRamp metering systems effectively reduce freeway congestion but often face public op- position due to inequitable delay distribution among users. This study addresses this challenge by introducing EqALINEA, a fairness-enhanced extension of the ALINEA algo- rithm designed to balance efficiency and equity in freeway access. Using microsimulations in SUMO, we evaluate ALINEA, Upstream ALINEA, and EqALINEA across both a simplified network and a real-world case study of Barcelona’s Ronda de Dalt corridor. Results indicate that traditional ALINEA prioritizes mainline throughput at the expense of spatial equity, disproportionately delaying on-ramp users near bottlenecks. EqALINEA mitigates these disparities by incorporating fairness constraints, including maximum waiting thresholds and proactive queue management. This approach leads to a more balanced distribution of delays while maintaining overall traffic efficiency within the simulation time. The algorithm adapts effectively to urban environments such as the Ronda de Dalt, where infrastructure limitations and evolving mobility policies require equitable traffic management solutions. This study demonstrates the feasibility of integrating fairness into decentralized ramp metering strategies to improve public acceptance and align with sustainable urban planning objectives.Outgoin
Hybridity, Identity and Micro-cosmopolitanism in the Ionian 19th century
No full textThe Ionian Islands, a complex of seven islands off the west coast of the Greek peninsula, historically and culturally constitute a contact zone between the Greek-speaking world and the West. In the 19th century, the islands, a former Venetian colony, experienced French and British colonial power before their incorporation in 1864 to the Greek state. This study focuses on the process of transformation of hybrid, cosmopolitan pre-national cultural identities into national schemes of appropriation and affiliation. Here, cultural agents, networking across linguistic, cultural, confessional or other borders, are exemplified by the example of the Lountzis brothers and their special link to the German-speaking world, its philosophy and its poetics. In this study, translation is scrutinised as a field of identity negotiation. It is also understood as a gesture of kinship with larger literary communities in the wider spectrum of the mobility of knowledge and ideas enabled by 19th century mystical sectarianism. The author of this book traces local micro-cosmopolitanism in the form of readership and identity performance, while cosmopolitanism, nationalism and sectarianism are viewed as interacting factors in the transformation of cultural, social and national identities in 19th century Europe.

"Laughing Word" in the Novel by Michail Bulgakov’s "The Mаster and Margarita"
Full text linkОсновна увага авторів зосереджена на розкритті специфіки комічного в романі М. О. Булгакова «Майстер і Маргарита», на використанні “чужого” слова, а також композиційних прийомів, що спричиняють виникнення комічних ефектів. Діапазон емоційних оцінок, які автор дає своїм комічним персонажам, дуже широкий: від в’їдливої іронії щодо членів літературної асоціації до гумористичних образів звичайних радянських громадян. У статті наведено приклади того, як М. О. Булгаков з нещадною іронією викриває порожнечу й штучність офіційно-канцелярського мовного стандарту, словесних штампів, що приховують справжню, природну сутність явищ. The relevance of the topic of this work is due to the attention of modern philologists to the personal aspect of language learning, to the study of linguistic means that characterize human intentionality; to the dynamic structure of the literary text associated with its existence in the communication “author – reader”. The main attention of the authors is focused on revealing the specifics of the comicality in Bulgakov’s novel «The Master and Margarita», using “someone else’s” words, as well as compositional techniques of representation, leading to comic effects. The range of emotional assessments that the author gives to his comic characters is very wide: from the scathing irony of the literary association memebers to the humorous images of ordinary Soviet citizens. The purpose of this article is to consider what stylistic devices are used by Michail Bulgakov to achieve comic and ironic effects in the novel «The Master and Margarita», creating images of characters. The purpose involves solving the following main tasks: – to consider the main types of comic - humor and irony and their functioning in the novel «The Master and Margarita»; – to identify and consider the basic techniques of organizing a comic text; – to identify and analyze the linguistic means of achieving a comic effect in the text of the novel by Michail Bulgakov. The article provides examples of how Bulgakov with ruthless irony exposes the emptiness and artificiality of the official-clerical language standard, verbal stamps that hide the true, natural essence of phenomena. He seeks to reflect genuine reality, not distorted by the “crooked mirror” of official bureaucratic phrases. The merry magical power of Bulgakov’s laughter is aimed at ridiculing the senseless reality that was idealized by official Soviet literature. There were clear signs of what Bakhtin called the “carnival worldview” and the spirit of ancient menippeiа in «The Master and Margarita»
