Stability of three-and four-charge systems
نویسنده
چکیده
A brief review is presented of the stability domain of threeand fourcharge ground-states when the constituent masses vary. Rigorous results are presented, based on the scaling behavior and the convexity properties deduced from the variational principle. They are supplemented by accurate numerical computations. Talk given at the Workshop Critical Stability, Les Houches, Oct. 8–12, 2001, to appear in the Proceedings, a special issue of Few-Body Systems E-mail: [email protected] Permanent address

Stability of Three-Wheeled Vehicles with and without Control System
In this study, stability control of a three-wheeled vehicle with two wheels on the front axle, a three-wheeled vehicle with two wheels on the rear axle, and a standard four-wheeled vehicle are compared. For vehicle dynamics control systems, the direct yaw moment control is considered as a suitable way of controlling the lateral motion of a vehicle during a severe driving maneuver. In accorda...

The formation of charge-transfer complexation between dibenzo-15-crown-5 (DB15C5) and benzo-12-crown-4 (B12C4) (Donor) and iodine is investigated spectrophotometrically in three chlorinated solvents,chloroform, dichloromethane (DCM) and 1,2-dichloroethane (DCE) solution at 25°C. The change in polarityof the solvent also doesn’t affect the stoichiometry of the complexes. Values of formation cons...
