The deflection of interstellar dust grains in the magnetic field near the heliopause depends on their surface electric charge. We study the electric charging of the grains with emphasis on the secondary electron emission because of its importance in the hot plasma environment near the heliopause. We correct previous models of the secondary electron emission that overestimate the electric charge...

Thermal energy for domestic hot water and heating use is stored in water tanks. Depending on the time of charging and the consumption the size of the storage tank has to be adjusted. In solar thermal systems, tanks sizes are typically around 0.3 – 0.5 cubic meter for single family houses and in case of seasonal storage systems up to several hundreds of cubic meters in district heating systems. ...

Topological state of matter and lithium batteries are currently two hot topics in science and technology. Here we combine these two by exploring the possibility of using all-carbon-based porous topological semimetal for lithium battery anode material. Based on density-functional theory and the cluster-expansion method, we find that the recently identified topological semimetal bco-C16 is a prom...

Road User Charging (RUC) solutions based on the concept of thin clients rely upon timely delivery of Heavy Goods Vehicles (HGV) positions towards a RUC provider, which then performs the map matching and the calculation of the road user charges. In order to avoid data loss and late delivery, a proper dimensioning of the system is required. For the Swedish case, we investigate the feasibility of ...

As the interdiscipline of wireless communication and control engineering, the periodical charging issue in Wireless Rechargeable Sensor Networks (WRSNs) is a popular research problem. However, existing techniques for periodical charging neglect to focus on the location relationship and topological feature, leading to large charging times and long traveling time. In this paper, we develop a hybr...

This paper studies the problem of multi-stage placement of electric vehicle (EV) charging stations with incremental EV penetration rates. A nested logit model is employed to analyze the charging preference of the individual consumer (EV owner), and predict the aggregated charging demand at the charging stations. The EV charging industry is modeled as an oligopoly where the entire market is domi...

The enormous growth in the penetration of electric vehicles (EVs), has laid the path to advancements in the charging infrastructure. Connectivity between charging stations is an essential prerequisite for future EV adoption to alleviate users’ “range anxiety”. The existing charging stations fail to adopt power provision allocation and scheduling management. To improve the existing charging infr...

The widespread diffusion of electric vehicles (EVs) suffers from the lack of a well-developed public charging infrastructure, which currently is uneconomical to develop for investors. Many owners of EVs have private charging stations at their premises, which yield unlockable potential due to high idling times. In line with sharing platforms for other goods like accommodations and cars, we prese...

I N RECENT TIMES, wireless power charging of electric vehicles (EV) has gained huge attentions. Static wireless charging for EVs has seamlessly been achieved using the inductive power transfer (IPT) technology. More recently, dynamic (also termed in-motion) wireless charging with IPT technology has been successfully demonstrated for electric mass transportation means like electric trains, trams...

The ACTS project on Contract Negotiation and Charging in ATM Networks (CANCAN) is now entering its second year. This paper will describe some of the activities of Work Package 2 in laying the foundation for the development of effective ATM charging schemes. Of great importance are the charging parameters which may be divided into access parameters considered at the registration of a service, an...
