First- and last-mile trips are becoming increasingly expensive detrimental to the environment, especially within dense cities. Thus, new micro-mobility transportation modes such as e-scooter sharing systems have been introduced fill gaps in network. Furthermore, some recent studies examined e-scooters a green option from standpoint of environmental sustainability. Currently, charging is conduct...

Shared automated vehicles are expected to be part of the supply transportation systems in future. Parallel this evolution, there is rapid penetration battery electric (BEVs). The limitations capacity and charging speed BEVs can influence planning operation shared vehicle (SAEV) systems. design such needs include these so that their viability properly estimated. In paper, we develop a space–time...

Most models of Bidirectional associative memories intend to achieve that all trained pattern correspond to stable states; however, this has not been possible. Also, none of the former models has been able to recall all the trained patterns. In this work we introduce a new model of bidirectional associative memory which is not iterative and has no stability problems. It is based on the Alpha-Bet...

Piezoelectric transformers (PTs) have been successfully applied as step-up transformers for backlighting Cold Cathode Fluorescent Lamp s (CCFL) used in the liquid crystal displays of notebook computers. In the last decade, the interest in PTs has evolved to a second group of applications. Worldwide companies are now investigating the use of PTs for power applications, including battery chargers...

The battery charging system is a critical part of a plug-in hybrid electric vehicle (PHEV). The efficiency, charging speed, and cost of such chargers are crucial to the commercialisation of PHEVs. In this paper, the advantages and drawbacks of four potential PHEV charger topologies were compared based on their operations through simulation and experiments. Their electrical stress, efficiency, c...

Electric Vehicles are becoming increasingly popular due to their environment friendly operation. As the demand for electric vehicles increases, it has become quite important explore charging strategies. Since and traction do not normally occur simultaneously power electronics converters both operations have some similarities, practice of integrating systems is popular. These types chargers term...

background: we sought to assess right ventricular (rv) systolic and diastolic functions via tissue doppler imaging (tdi) in order to discriminate right-to-left (bidirectional) from left-to-right intracardiac shunts. methods: a tissue doppler velocity study via doppler echocardiography was performed in 20 patients with left-to-right shunt (without evidence of significant pulmonary hypertension) ...

Inverter is truly the nucleus of electronics industry. It is the main building block of everyday appliances i. e. microwaves, power tools, battery chargers, air conditioners and computers etc. In this paper, CMOS technology has been chosen to study the transient and dc characteristics of an inverter. Feature size is the main parameter to study the voltage transfer characteristics of inverter, f...
