The dynamic model of redundantly actuated mobile robots with powered caster wheels is derived based on vehicle dynamics. The contact stability problem of wheeled mobile robots is introduced and stable contact condition that characterizes the bounds of contact stability is derived. Sliding mode observer is proposed to estimate the robot velocity using wheel angular velocity and joint torque info...
We review and correct the classical critical exponents characterizing the transition from negative to positive black hole’s heat capacity at high charge– angular momentum. We discuss the stability properties of black holes as a thermodynamic system in equilibrium with a radiation bath (canonical ensamble) by using the Helmholtz free energy potential. We finally analytically extend the analysis ...
contact dermatitis is an inflammatory reaction of the skin and mucosa to either external or internal factors. it can be divided to two forms of irritant contact dermatitis and allergic contact dermatitis. nickel is one of the most common materials that causes allergic contact dermatitis and is widely used in orthodontic appliances. the inflammatory reaction to this metal in orthodontics is usua...
Many extant studies proposed various stabilizing control methods for humanoids during the stance phase while hopping and running. Although these methods contribute to stability during hopping and running, humanoid robots do not swing their legs rapidly during the flight phase to prevent rotation in the yaw direction. Humans utilize their torsos and arms when running to compensate for the angula...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
