“…There are other isotopes 17 O and 18 O which occupy only 2.4 100 % of all isotopes of oxygen. When the temperature is lower, the ratio of the lighter oxygen isotope 16 O increases since it vapors into the air and gets frozen in snow form. The ratio of the lighter oxygen isotope in ice-core and the snow crystal is the same.…”

In this paper we set up foundations for vehicle dynamics and apply them to possible future EVs-wireless in-wheel motor elctric vehicles (wirelsee IWMEVs)-in the coming green grid (GG) era. GG is the most advanced form of the coming smart gird in which electricity is to be generated only through harmless resources, mainly solar energy. All the cars are to be EVs which are wirelessly connected to the GG through a regional aggregator which survey the area and in case of need, the emergency signal is to be sent to the vehicle to make a necessary action for collision avoiding. We also discuss the climate change in general and global warming in particular and state why global warming is a grave issue for the human being through archeo-climatology. We state a plausible waether-cycle conjecture of 1470 years as a combination of conjectures of H. Noshioka and the latest ones based on the Dansgaard-Oeschger (DO) cycles.

SUMMARYAn indoor four-wheel individual steering and driving vehicle with full electronics was built for evaluation of the system's ability and the performance in practical use. Mechanical parts such as the connecting rod and the differential gear are not provided for this vehicle.From trial operation, the characteristics fully performed as in design, but some problems originating from the design concept were disclosed.Rotating radius (R) of the vehicle was taken for the steering command parameter, but it was found to not be an appropriate parameter for driving operation. The reasons are as follows:1) R has a much different sense of driving conformability for the driver, because it does not refer to the running direction, but to the rotating radius of crosswise direction.2) Sensitivity of each wheel steering angle versus R differs over double figures in the full range of R.3) R changed from plus to minus and also vice versa in most practical situations around straight-go operation.For these reasons, the steering command parameter was changed from R to α, where α is the angle between the vehicle lengthwise direction and the moving direction. The steering control algorithm using α has been proven to solve the three above-mentioned problems.
