The introduction of electric mobility into the transport sector has significantly contributed to mitigation environmental issues [...]

Electrification of the transportation sector has originated a worldwide demand towards green-based refueling infrastructure modernization. Global researches and efforts have been pondered to promote optimal Electric Vehicle (EV) charging stations. The EV power electronic systems can be classified into three main divisions: station configuration (e.g., Level 1 (i.e., slow-speed charger), 2 fast-...

Malfunction of the unidirectional valve in a breathing circuit system may cause hypercapnia from the rebreathing of expired gas, ventilation failure, and barotrauma. Capnography is a useful method for monitoring the integrity of the unidirectional valve. We experienced two cases of malfunction of a unidirectional valve which caused leakage and reverse flow, diagnosed early as a change of the ca...

State-of-the-art ultra-fast battery chargers for electric vehicles simultaneously require high efficiency and power density, leading to a challenging converter design. In particular, the grid-side filter, which ensures sinusoidal current absorption with low pulse-width modulation (PWM) harmonic content, can be major contributor overall size losses. Therefore, this paper proposes complete analys...

5 Abstract—The application Q1 of wireless charging technology in traditional battery-powered wireless sensor networks (WSNs) grows 6 rapidly recently. Although previous studies indicate that the technology can deliver energy reliably, it still faces regulatory mandate to 7 provide high power density without incurring health risks. In particular, in clustered WSNs there exists a mismatch between...

It is shown that a unidirectional link of a network can be used for routing only if it has an inclusive cycle, which is a path that can carry routing updates from the downstream node to the upstream node joined by the unidirectional link. A new routing algorithm for networks with unidirectional links is then presented, which incrementally disseminates linkstate information and selectively utili...

A distributed algorithm is self-stabilizing if after faults and attacks hit the system and place it in some arbitrary global state, the system recovers from this catastrophic situation without external intervention in finite time. Unidirectional networks preclude many common techniques in self-stabilization from being used, such as preserving local predicates. The focus of this work is on the c...

Compactness as introduced by Botafogo, Rivlin and Shneiderman, in short: BRScompactness, is studied in general, as it can be used to describe the cohesion of parts of the lnternet or collaboration networks, and in the particular case of a unidirectional network, such as a citation graph. It is shown that the connection coefficient is an upper bound for the BRS-compactness value of a network. Du...

In recent years, car-sharing systems have been announced as a way to increase mobility and to decrease the number of single-occupant vehicles, congestion, and air pollution in many parts of the world. This study presents a linear programming model to optimize one-way car-sharing systems for electric cars considering the depreciation costs of chargers and vehicles as well as relocation cost of v...
