Abstract Combining the anomalies and environmental monitoring data of early stage Beidou satellites, space radiation environment spatial/temporal distribution effect risk characteristics are analyzed, dynamic factors, such as hot plasma, high-energy electron solar proton summarized. The systematic joint for surface charging, internal single event total dose with corresponding factors is propose...

Mobile communication networks need an overall holistic concept for their charging and billing processes, independently of the kinds of services in use. All usage data of a single service should finally be summarized in a single service-oriented complete bill, which shows the individual components of a service separately. In the case of handover among different access networks at the application...

This paper deals with the Electric Vehicle Scheduling and Optimal Charging Problem. More precisely, given a fleet of Electric Vehicles EVs and Combustion Engine Vehicles CVs, a set of tours to be processed by vehicles and a charging infrastructure, the problem aims to optimize the assignment of vehicles to tours and minimize the charging cost of EVs, while considering several operational constr...

The economic and environmental benefits brought by electric vehicles (EVs) cannot be fully delivered unless these vehicles are fully or partially charged by renewable energy sources (RES) such as photovoltaic system (PVS). Nevertheless, the EV charging management problem of a parking station integrated with RES is challenging due to the uncertain nature of local RES generation. This paper aims ...

In practice, mobile network operators, service and content providers, equipment vendors, handset manufacturers and software developers need to co-operate to bring efficient location-based services in the daily life of mobile consumers. The provision of advanced location-based services is a big opportunity for all business players involved to increase their revenues. Therefore, charging and bill...

As the number of Plug-in Electric Vehicles (PEVs) increases, it is essential to control their charging schedules and spread the PEV load over time to reduce the energy generation and distribution costs due to this additional demand. Furthermore, due to the limited power capacity of the transmission feeders and the sensitivity of the mid-way distribution transformers to excessive load, it is cru...

Supercapacitors (or electric double-layer capacitors) are high-power energy storage devices that store charge at the interface between porous carbon electrodes and an electrolyte solution. These devices are already employed in heavy electric vehicles and electronic devices, and can complement batteries in a more sustainable future. Their widespread application could be facilitated by the develo...

The optimal scheduling of crude-oil operation in refineries has been researched by various groups during the past decade. Different mixed integer linear programming or mixed nonlinear programming formulations are derived. This paper proposes a novel MINLP formulation with multiple charging tanks charging a distiller overlapingly and oil residency time constraint that is based on multi-operation...

This paper addresses the modelling and simulation of a battery charging infrastructure for electric vehicles, with the objective of pro-actively scheduling the charging of up to fifty vehicles so as not to overcharge the electrical network. Benefits of having the charging stations differ (as much as possible while satisfying end-user requirements) battery charging for those hours when electrici...

Temperature acceleration of dielectriccharging effects in state-of-the-art RF MEMS capacitive switches was characterized and modeled. From the measured charging and discharging transient currents across the switching dielectric, densities and time constants of traps in the dielectric were extracted under different temperatures. It was found that, while charging and discharging time constants ar...
