For sustainable electrification of surface transportation, a viable charging infrastructure is necessary. Firstly, this paper focuses on emphasizing the viability of a free fuel-based photovoltaics and/or wind turbines and lithium-ion battery-based power network to enable sustainable electric power. The importance of power electronics for a DC-based power network and extremely fast charger based on DC power is presented. Finally, the core design concepts of intelligent charging infrastructure using an intelligent energy management system are discussed. The paper aims to cover all aspects associated with a clean, reliable, efficient, and cost-effective solution to the novel charging infrastructure.

The expansion of electric vehicles made the expansion of charging infrastructure rudimentary to keep up with this developing technology that helps people in a myriad of ways. The main drawback in electric vehicle charging, however, is the time consumed to charge a vehicle. The fast charging of electric vehicles solves this problem thus making it a lucrative technology for consumers. However, the fast charging technology is not without its limitations. In this paper we have identified the technology gaps in EV fast charging stations mostly focused on the extremely fast charging topology. It will help pave a path for researchers to direct their effort in a consolidated manner to contribute to the fast charging infrastructure. A thorough review of all aspects and limitations of existing extremely fast charging (XFC) stations have been identified and supporting data are provided. The importance of DC power network based on free fuel energy sources and silicon carbide-based power electronics are proposed to provide ultra-low cost and ultra-high speed XFC stations.

This article considers the politics and aesthetics of the colonial Bildungsroman by reading George Moore's often-overlooked novel A Drama in Muslin (1886). It argues that the colonial Bildungsroman does not simply register difference from the metropolitan novel of development or express tension between the core and periphery, as Jed Esty suggests, but rather can imagine a heterogeneous historical time that does not find its end in the nation-state. A Drama in Muslin combines naturalist and realist modes, and moves between Ireland and England to construct a form of untimely development that emphasises political processes (dissent, negotiation) rather than political forms (the state, the nation). Ultimately, the messy, discordant history represented in the novel shows the political potential of anachronism as it celebrates the untimeliness of everyday life.

AbstractTom Kristensen’s travel book En Kavaler i Spanien (1926) was the result of a stay at the Danish explorer Knud Rasmussen’s house, where Kristensen not only met his physical and psychological superior, he also began his artistic development and personal breakdown towards the novel Hærværk (1930). The article argues that with a departure from this context, En Kavaler i Spanien can be read as an original and complex subgenre of the sentimental novel and it suggests that the work might best be categorized as ‘hard sentimentalism’. This subgenre of the travel novel can be identified in the intertwinement of the core thematic of the book — eroticism, medieval Spain and identity loss — with style and form. The paradoxical generic notion of ‘hard sentimentalism’ is used to connect medieval Spain with the erotic, but in an increasingly dangerous way, which threatens the traveler’s identity by increasing homosexual attraction and opening an abyss of degeneration and distorted emptiness behind the flirt.

AbstractMaximize Presupposition! (MP), as originally proposed in Heim (Semantik: Ein internationales Handbuch der zeitgenössischen Forschung, pp. 487–535, 1991) and developed in subsequent works, offers an account of the otherwise mysterious unassertability of a variety of sentences. At the core of MP is the idea that speakers are urged to use a sentence ψ over a sentence ϕ if ψ contributes the same new information as ϕ, yet carries a stronger presupposition. While MP has been refined in many ways throughout the years, most (if not all) of its formulations have retained this characterisation of the MP-competition. Recently, however, the empirical adequacy of this characterisation has been questioned in light of certain newly discovered cases that are infelicitous, despite meeting MP-competition conditions. This has led some researchers to broaden the scope of MP, extending it to competition between sentences which are not contextually equivalent (Spector and Sudo in Linguistics and Philosophy 40(5):473–517, 2017) and whose presuppositions are not satisfied in the context (Anvari in Proceedings of Semantics and Linguistic Theory 28, pp. 711–726, 2018; Manuscript, IJN-ENS, 2019). In this paper, we present a body of evidence showing that these formulations of MP are sometimes too liberal, sometimes too restrictive: they overgenerate infelicity for a variety of felicitous cases while leaving the infelicity of minimally different cases unaccounted for. We propose an alternative, implicature-based approach stemming from Magri (PhD dissertation, MIT, 2009), Meyer (PhD dissertation, MIT, 2013), and Marty (PhD dissertation, MIT, 2017), which reintroduces contextual equivalence and presupposition satisfaction in some form through the notion of relevance. This approach is shown to account for the classical and most of the novel cases. Yet some of the latter remain problematic for this approach as well. We end the paper with a systematic comparison of the different approaches to MP and MP-like phenomena, covering both the classical and the novel cases. All in all, the issue of how to properly restrict the competition for MP-like phenomena remains an important challenge for all accounts in the literature.

Plummeting reserves and increasing demand of freshwater resources have culminated into a global water crisis. Desalination is a potential solution to mitigate the freshwater shortage. However, the process of desalination is expensive and energy-intensive. Due to the water-energy-climate nexus, there is an urgent need to provide sustainable low-cost electrical power for desalination that has the lowest impact on climate and related ecosystem challenges. For a large-scale reverse osmosis desalination plant, we have proposed the design and analysis of a photovoltaics and battery-based stand-alone direct current power network. The design methodology focusses on appropriate sizing, optimum tilt and temperature compensation techniques based on 10 years of irradiation data for the Carlsbad Desalination Plant in California, USA. A decision-tree approach is employed for ensuring hourly load-generation balance. The power flow analysis evaluates self-sufficient generation even during cloud cover contingencies. The primary goal of the proposed system is to maximize the utilization of generated photovoltaic power and battery energy storage with minimal conversions and transmission losses. The direct current based topology includes high-voltage transmission, on-the-spot local inversion, situational awareness and cyber security features. Lastly, economic feasibility of the proposed system is carried out for a plant lifetime of 30 years. The variable effect of utility-scale battery storage costs for 16–18 h of operation is studied. Our results show that the proposed design will provide low electricity costs ranging from 3.79 to 6.43 ¢/kWh depending on the debt rate. Without employing the concept of baseload electric power, photovoltaics and battery-based direct current power networks for large-scale desalination plants can achieve tremendous energy savings and cost reduction with negligible carbon footprint, thereby providing affordable water for all.

Literary geography is one of the core aspects of the study of the novel, both in its realist and post-realist incarnations. Literary geography is not just about connecting place-names to locations on the map; literary geographers also explore how spaces interact in fictional worlds and the imaginary of physical space as seen through the lens of characters' perceptions. The tools of literary cartography and geographical analysis can be particularly useful in seeing how places relate to one another and how characters are associated with specific places. This Element explores the literary geographies of Balzac and Proust as exemplary of realist and post-realist traditions of place-making in novelistic spaces. The central concern of this Element is how literary cartography, or the mapping of place-names, can contribute to our understanding of place-making in the novel.

Typical application of bidirectional DC/DC power converter exists in hybrid cars. Recently, a similar approach has been applied in hybrid propelled ships as well. In this paper, a novel low power bidirectional DC/DC power converter of standard Buck/Boost topology has ben designed in order to explore possibilities of the high power design in maritime applications. In order to discover critical points of a design, thermal imaging has been investigated. The results clearly indicate that the proposed solution is more cost effective than a typical standard bidirectional DC/DC power converter. Likewise, the improvement in maneuvering of the propelled vessel system with two and more electric drives has been investigated and compared to a classical diesel, single engine propulsion system.
