background: in the aftermath of the great east japan earthquake, most of the areas in yamagata prefecture experienced a serious power failure lasting for approximately 24 hours. a number of households were subsequently poisoned with carbon monoxide (co) due to various causes. in this study, we conducted a survey of co poisoning during the disaster. methods: a questionnaire regarding co poisonin...

The dwindling energy resources and the compliance of international climate protection goals lead to a rethink in the automobile sector. One result of this rethink is the increasing distribution of electric vehicles in the last years. This development includes a new challenge for the training sector. For example, the implementation of a highvoltage system into automobiles involves a new hazard p...

Electric discharge drill machine (EDDM) is a spark erosion process to produce micro-holes in conductive materials. This process is widely used in aerospace, medical, dental and automobile industries. As for the performance evaluation of the electric discharge drilling machine, it is very necessary to study the process parameters of machine tool. In this research paper, a brass rod 2 mm diameter...

In electric vehicles that use in-wheel motors, the right and left traction forces become unbalanced if a motor malfunctions by motor lock or loss of traction, generating yaw moment. Control methods were designed to reduce this effect by stopping the motor output on the opposite side of the same axle. By using a prototype “Eliica” car, the maximum yaw rate and lateral acceleration were compared ...

This paper compares the manufacturing and refueling costs of a Fuel-Cell Vehicle (FCV) and a Battery Electric Vehicle (BEV) using an automobile model reflecting the largest segment of light-duty vehicles. We use results from widely-cited government studies to compare the manufacturing and refueling costs of a BEV and a FCV capable of delivering 135 horsepower and driving approximately 300 miles...

“Carbon Neutrality” means that enterprises, groups, or individuals calculate the total amount of greenhouse gas emissions produced directly indirectly within a certain period and offset their Carbon dioxide through afforestation, energy conservation, emission reduction to achieve zero carbon emissions. Since 2020, commitment Neutrality has been paid attention by various industries. Particularly...

Compared with vehicles powered by fuel, electric are more efficient in energy saving, emission reduction, and environmental protection. As a result, it is becoming most important applications the transportation sector. Electric usage growing from day to (EVs) will become reality future. The time taking method of charging an EV becomes major problem accept electronic revolution automobile indust...
